    Full Text Available Leishmaniasis is a reemerging disease of worldwide distribution and has a public health importance. It is an infectious disease, parasitical and clinical severity ranging from a healthy appearance to a severe stage. Features two major forms, such as cutaneous leishmaniasis (cutaneous and mucocutaneous and visceral leishmaniasis. This form can be deadly for reaching the organs. The four main protozoa that cause such clinical manifestations are Leishmania chagasi, Leishmania braziliensis, Leishmania amazonensis and Leishmania guyanensis. Environment, social and demographic factors are key for the transmission of leishmaniasis, due to its vector being a sand fly - insect with hematophagous habits - and its main reservoir are dogs. In Brazil, leishmaniasis is endemic and widely distributed. 80% of reported cases are in children under 10 years. The Legal Amazon region is an area of study of public health, having suffered anthropogenic actions that undermine the ecological balance of the site. In this area, visceral leishmaniasis is increasing in western Pará state due to its economic development, which involves the public health. This study aims to relate environmental and health factors with the incidence of leishmaniasis in the Legal Amazon and this relationship will be used secondary data from publications in the National Health Information System (NHIS.

  2. Social-Ecological Changes in a Quilombola Community in the Atlantic Forest of Southeastern Brazil.

    Thorkildsen, Kjersti

    2014-01-01

    Through a combined adaptive cycle and political ecology approach, this article explores how the Afro-Brazilian Quilombolas of Bombas, living inside the protected area of PETAR, respond to and shape social-ecological changes in the Atlantic Forest. Field data reveal that both environmental restrictions and social policies of state transfer payments and food packages have contributed to decreased engagement in agricultural practices, loss of traditional knowledge, and reduced agro-biodiversity. The claim to land rights based on a Quilombola identity and recent negotiations with forest authorities insinuate a shift of this trend. Contrary to dominant conservation narratives, the findings indicate that small-scale shifting cultivation practices by the Quilombolas have the potential to increase structural ecological complexity of the Atlantic Forest. The article therefore argues that legalization of settlement and subsistence activities is important not only for livelihood security and social cohesion of Bombas inhabitants, but also possibly for biodiversity conservation.

  3. Unpacking Changes in Mangrove Social-Ecological Systems: Lessons from Brazil, Zanzibar, and Vietnam

    Full Text Available Mangroves provide multiple benefits, from carbon storage and shoreline protection to food and energy for natural resource-dependent coastal communities. However, they are coming under increasing pressure from climate change, coastal development, and aquaculture. There is increasing need to better understand the changes mangroves face and whether these changes differ or are similar in different parts of the world. Using a multiple case study approach, focused on Vietnam, Zanzibar, and Brazil, this research analyzed the drivers, pressures, states, impacts, and responses (DPSIR of mangrove systems. A qualitative content analysis was used on a purposively sampled document set for each country to identify and collate evidence under each of the DPSIR categories. Population growth and changing political and economic processes were key drivers across the three countries, leading to land use change and declining states of mangroves. This had an impact on the delivery of regulatory and provisioning ecosystem services from mangroves and on the welfare of coastal communities. Responses have been predominantly regulatory and aim to improve mangrove states, but without always considering ecosystem services or the consequences for welfare. The issue of scale emerged as a critical factor with drivers, pressures, impacts, and responses operating at different levels (from international to local, with consequences for response effectiveness.

    This paper describes the practice of sociodrama, a method created by J. L. Moreno in the 1930s, and the Brazilian contemporary socio-psychodrama. In 1970, after the Fifth International Congress of Psychodrama was held in Brazil, group psychotherapy began to flourish both in private practice and hospital clinical settings. Twenty years later, the Brazilian health care system added group work as a reimbursable mental health procedure to improve social health policies. In this context, socio-psychodrama became a key resource for social health promotion within groups. Some specific conceptual contributions by Brazilians on sociodrama are also noteworthy.

Such practices, although often viewed as initiatives to improve a degraded environment, also foster social attributes of resilient social-ecological systems,…

  6. Mapping Social Ecological Systems Archetypes

    2016-12-01

    Achieving sustainable development goals requires targeting and monitoring sustainable solutions tailored to different social and ecological contexts. Elinor Ostrom stressed that there is no panaceas or universal solutions to environmental problems, and developed a social-ecological systems' (SES) framework -a nested multi tier set of variables- to help diagnose problems, identify complex interactions, and solutions tailored to each SES arena. However, to our knowledge, the SES framework has only been applied to over a hundred cases, and typically reflect the analysis of local case studies with relatively small coverage in space and time. While case studies are context rich and necessary, their conclusions might not reach policy making instances. Here we develop a data driven method for upscaling Ostrom's SES framework and applied to a context where we expect data is scarce, incomplete, but also where sustainable solutions are badly needed. The purpose of upscaling the framework is to create a tool that facilitates decision making on data scarce environments such as developing countries. We mapped SES by applying the SES framework to poverty alleviation and food security issues in the Volta River basin in Ghana and Burkina Faso. We found archetypical configurations of SES in space given data availability, we study their change over time, and discuss where agricultural innovations such as water reservoirs might have a stronger impact at increasing food security and therefore alleviating poverty and hunger. We conclude outlining how the method can be used in other SES comparative studies.

    Full Text Available This article discusses the role of social and environmental enterprises revealed in the concept of Corporate Social Responsibility (CSR and analyzed in the light of Ecological Modernization Theory (TME.The overall objective of this study is to understand CSR from the perspectiveof TME through more detailed research of a CSR program called  Clube dos Produtores [Producers Club].This program aims to influence the supply chain to adopt responsible and sustainable practices, and seeks to strengthen the small and medium producers through structured actions, such as training, qualification, and inspection, stimulating quality, innovation and productivity growth. It is conducted in parallel, in Portugal, by the Rede Sonae de Distribuição and, in Brazil, by Walmart Company. The data collection included both Countries. In Portugal, the Clube dos Produtores has emerged to combine the synergy between distribution and production and promote the development of domestic production. It takes the environment as the genesis for its creation, maintains a nationalist approach by encouraging the consumption of domestic products, and recognizes consumer pressure as the force for continuous innovation of products and services. In addition, it reconciles tradition and modernity through products supported by different generations. In Brazil, the Club is founded on the sustainability discourse; the customer awareness about environmental issues was not captured in the research; the producers innovations result from their own initiatives to participate in fairs or from direct contact with consumers; the dialogue between tradition and modernity occurs primarily through the entrepreneurial capacity of the producers and less direct intervention by Walmart.

  9. Brazil's Amazonian dams: Ecological and socioeconomic impacts

    Science.gov (United States)

    Fearnside, P. M.

    2016-12-01

    Brazil's 2015-2024 Energy Expansion Plan calls for 11 hydroelectric dams with installed capacity ≥ 30 MW in the country's Amazon region. Dozens of other large dams are planned beyond this time horizon, and dams with consumers. Population displacement is a major impact; for example, the Marabá Dam would displace 40,000 people, mostly traditional riverside dwellers (ribeirinhos). Various dams impact indigenous peoples, such as the Xingu River dams (beginning with Belo Monte) and the São Luiz do Tapajós and Chacorão Dams on the Tapajós River. Brazil has many energy options other than dams. Much energy use has little benefit for the country, such as exporting aluminum. Electric showerheads use 5% of the country's power. Losses in transmission lines (20%) are far above global averages and can be expected to increase as Amazonian hydroelectric dams far from consumer centers come on line. Brazil has tremendous wind and solar potential, but these do not have the same priority as dams. At the root of many questionable policies is a decision-making process in need of reform.

  10. An ecological study on suicide and homicide in Brazil.

    2014-04-01

    The objective was to evaluate correlations between suicide, homicide and socio-demographic variables by an ecological study. Mortality and socio-demographic data were collected from official records of the Ministry of Health and IBGE (2010), aggregated by state (27). The data were analyzed using correlation techniques, factor analysis, principal component analysis with a varimax rotation and multiple linear regression. Suicide age-adjusted rates for the total population, men and women were 5.0, 8.0, and 2.2 per 100,000 inhabitants respectively. The suicide rates ranged from 2.7 in Pará to 9.1 in Rio Grande do Sul. Homicide for the total population, men and women were 27.2, 50.8, and 4.5 per 100,000, respectively. The homicide rates ranged from 13.0 in Santa Catarina to 68.9 in Alagoas. Suicide and homicide were negatively associated, the significance persisted among men. Unemployment was negatively correlated with suicide and positively with homicide. Different socio-demographic variables were found to correlate with suicide and homicide in the regressions. Suicide showed a pattern suggesting that, in Brazil, it is related to high socioeconomic status. Homicide seemed to follow the pattern found in other countries, associated with lower social and economic status.

  11. Social ecological complexity and resilience processes.

    Science.gov (United States)

    Ungar, Michael

    2015-01-01

    A social ecological model of resilience avoids the reductionism of simple explanations of the complex and multisystemic processes associated with well-being in contexts of adversity. There is evidence that when stressors are abnormally high, environmental factors account for more of an individual's resilience than do individual traits or cognitions. In this commentary, a social ecological model of resilience is discussed.

    Carlos Antonio Costa Ribeiro

    2007-01-01

    Full Text Available This article analyzes the differences in inter-generational social mobility and schooling between white, brown, and black men in Brazil. The main objective is to analyze inequality of opportunities for mobility and educational transitions. The results indicate that for individuals from lower social origins, inequality of opportunities is significantly marked by racial differences, and that for persons originating in the upper classes, racial inequality influences the odds of social mobility. The results suggest that theories of stratification by race and class in Brazil should be rethought, taking into account the observed interactions between race and class.

  14. Social Enterprises in Brazil: Socially Produced Knowledge Versus Social Innovation.

    Directory of Open Access Journals (Sweden)

    Edileusa Godói-de-Sousa

    2013-04-01

    Full Text Available This study investigated whether socially produced knowledge in social ventures in Brazil has promoted social innovation and local development. The research is exploratory and descriptive, and was developed in two stages. At first, the sample group was composed of 378 projects selected from the mapping of Solidarity Economic Enterprises, conducted by the National Secretary of Solidarity Economy (Secretaria Nacional de Economia Solidária. The sample was surveyed to verify the main characteristics of these enterprises. After that, interviews were conducted with key managers in a sample of 32 projects. The results indicate challenges in the long path of favoring dynamic learning, with a generation of knowledge from the collective experiences of socialization: there is a lack of joint discussion and a predominance of individualized learning actions.

  15. Social-Ecological Guilds: Putting People into Marine Historical Ecology

    Directory of Open Access Journals (Sweden)

    Janna M. Shackeroff

    2011-03-01

    Full Text Available Marine historical ecology provides historic insights into past ocean ecosystems that are crucial to effectively confronting the declining health and resilience in marine ecosystems. A more 'peopled' approach to marine historical ecology is necessary, given the heightened emphasis on human dimensions in marine management. This study examined the historical ecology of Hawaiian coral reef ecosystems through oral histories of diverse ocean experts, representing six traditional, local, and scientific knowledge systems. Based on 61 in-depth interviews with these ocean experts, historical trends, abundance, and distribution over 80 years and a 50-mile region for 271 species emerged. Analyzing trends by ecological guild, e.g., herbivores, proved inappropriate to these data; rather, based on qualitative analyses, five distinct trends encompassing nearly all species emerged in what we term "social-ecological guilds." Ocean expert's observations of change were surprisingly consistent, regardless of their knowledge system, whereas perceptions of change varied widely. The historical picture was far broader and richer when the contributions of six knowledge systems were incorporated, compared to that of any one alone. Social-ecological guilds also matter critically from a management perspective, because understanding how experts from a multiplicity of perspectives observe, interpret, and respond to ecological change can help managers anticipate responses to management activities and perhaps to design better management strategies.

    Full Text Available Law plays an essential role in shaping natural resource and environmental policy, but unfortunately, many environmental laws were developed around the prevailing scientific understanding that there was a "balance of nature" that could be managed and sustained. This view assumes that natural resource managers have the capacity to predict the behavior of ecological systems, know what its important functional components are, and successfully predict the outcome of management interventions. This paper takes on this problem by summarizing and synthesizing the contributions to this Special Feature (Law and Social-Ecological Resilience, Part I: Contributions from Resilience 2011, focusing on the interaction of law and social-ecological resilience, and then offering recommendations for the integration of law and social-ecological resilience.

  19. Social-ecological resilience and geomorphic systems

    Chaffin, Brian C.; Scown, Murray

    2018-03-01

    Governance of coupled social-ecological systems (SESs) and the underlying geomorphic processes that structure and alter Earth's surface is a key challenge for global sustainability amid the increasing uncertainty and change that defines the Anthropocene. Social-ecological resilience as a concept of scientific inquiry has contributed to new understandings of the dynamics of change in SESs, increasing our ability to contextualize and implement governance in these systems. Often, however, the importance of geomorphic change and geomorphological knowledge is somewhat missing from processes employed to inform SES governance. In this contribution, we argue that geomorphology and social-ecological resilience research should be integrated to improve governance toward sustainability. We first provide definitions of engineering, ecological, community, and social-ecological resilience and then explore the use of these concepts within and alongside geomorphology in the literature. While ecological studies often consider geomorphology as an important factor influencing the resilience of ecosystems and geomorphological studies often consider the engineering resilience of geomorphic systems of interest, very few studies define and employ a social-ecological resilience framing and explicitly link the concept to geomorphic systems. We present five key concepts-scale, feedbacks, state or regime, thresholds and regime shifts, and humans as part of the system-which we believe can help explicitly link important aspects of social-ecological resilience inquiry and geomorphological inquiry in order to strengthen the impact of both lines of research. Finally, we discuss how these five concepts might be used to integrate social-ecological resilience and geomorphology to better understand change in, and inform governance of, SESs. To compound these dynamics of resilience, complex systems are nested and cross-scale interactions from smaller and larger scales relative to the system of interest

    Authors working on "industrial metabolism" or "social metabolism" look at the economy in terms of flows of energy and materials. Together with the ecological economists, they see the economy as a subsystem of a larger physical system. Marx and Engels followed with a few years' delay many of the remarkable scientific and technical novelties of their time.

    Full Text Available The rural population lives in socioeconomic inequality conditions motivated by several problems, including an insufficient sewage systems and water supply, these, sometimes, most responsibles by the appearance of waterborne diseases that contribute to the rise of child mortality and other problems. Rural areas in Brazil are defined by opposition and exclusion in urban areas. This definition is arbitrary and physical-geographic, not considering the social and economic processes involving the territories. This study purposed to verify, by means of sociodemographic aspects, environmental sanitation and main grievances/diseases importance for public health of the population from forest field and water, if the most rural municipalities (MMR are more precarious than the more urban (MMU. To this end, was carried out a descriptive study based on secondary sources (Atlas of Human Development in Brazil, IBGE census, PNAD and Sinan. Among the results, it follows that the rural population identified by IBGE boils down to 15.6% of Brazil’s population. In 29% of the municipalities, the population living in rural areas exceeds the city. The higher frequencies from IDMH very low are for MMR, while the higher frequency from IDMH very high and high are for MMU. In health, the MMR also exhibit deficiency. It was observed high incidence rates of diseases related to poor conditions of sanitation. From these results, it was identified a more precarious health profile in MMR when compared to MMU.

  7. Ecological psychology and social psychology: continuing discussion.

    Science.gov (United States)

    Charles, Eric P

    2012-06-01

    What form would an ideal merger of ecological and social psychology take? Is that ideal attainable? Many researchers and theorists are working to answer these questions. Charles (2009, 2011a) offered insights from E. B. Holt, one of James J. Gibson's mentors, who argued that minds-mental kinds, processes, states, etc.-are observable aspects of the environment. Phrasing that in Ecological terms, the minds of other organisms are specified in the structure of ambient energy extended over time and space; they are directly perceivable by a properly attuned organism. Ecological Psychology enhances Holt's story, by brining to the table a sophisticated theory of direct perception; Holt enhances the Ecological story by brining to the table a sophisticated theory about the nature of minds. The two combine to form the long-sought ideal merger. Thus, I claimed, Ecological Psychology will either rediscover its roots, or go through the trouble of re-creating them. This paper further develops those ideas, by presenting a simpler version of the argument, suggesting easy ways of dismissing that argument, and addressing the concerns expressed by Castro and Lafuente (2011).

    2011-09-01

    Full Text Available This article examines the social representations of water in urban cultures of Argentina, placing the subject as a matter of academic and practical interest. Some questions have guided this investigation—What is water for the urban dweller? What are the actions that a citizen is willing to exercise?—A qualitative research was conducted (according to Yin’s case analysis methodology in Gualeguaychú and Buenos Aires. Following the collected data, the authors reconstructed the dominant paradigm in both cities, which was the ecocentric model. However, the acceptance of ecological values and beliefs is not an indicator of the exercise of proecological behavior concerning water. Empirical findings have guided the authors to inquire the degree of relationship between social representations and attributes of Andrew Dobson’s model of ecological citizenship.

  9. Social-ecological systems, social diversity, and power: insights from anthropology and political ecology

    Directory of Open Access Journals (Sweden)

    Michael Fabinyi

    2014-12-01

    Full Text Available A social-ecological system (SES framework increasingly underpins the "resilience paradigm." As with all models, the SES comes with particular biases. We explore these key biases. We critically examine how the SES resilience literature has attempted to define and analyze the social arena. We argue that much SES literature defines people's interests and livelihoods as concerned primarily with the environment, and thereby underplays the role of other motivations and social institutions. We also highlight the SES resilience literature's focus on institutions and organized social units, which misses key aspects of social diversity and power. Our key premise is the importance of inter- and multi-disciplinary perspectives. To illustrate this, we draw attention to the critique of earlier ecological anthropology that remains relevant for current conceptualizations of SESs, focusing on the concepts of social diversity and power. And we discuss insights from social anthropology and political ecology that have responded to this critique to develop different ways of incorporating social diversity and power into human-environment relations. Finally, we discuss how these social science perspectives can help improve the understanding of the "social" in SES resilience research.

    Cumming, Graeme S; Allen, Craig R

    2017-09-01

    Conservation biology and applied ecology increasingly recognize that natural resource management is both an outcome and a driver of social, economic, and ecological dynamics. Protected areas offer a fundamental approach to conserving ecosystems, but they are also social-ecological systems whose ecological management and sustainability are heavily influenced by people. This editorial, and the papers in the invited feature that it introduces, discuss three emerging themes in social-ecological systems approaches to understanding protected areas: (1) the resilience and sustainability of protected areas, including analyses of their internal dynamics, their effectiveness, and the resilience of the landscapes within which they occur; (2) the relevance of spatial context and scale for protected areas, including such factors as geographic connectivity, context, exchanges between protected areas and their surrounding landscapes, and scale dependency in the provision of ecosystem services; and (3) efforts to reframe what protected areas are and how they both define and are defined by the relationships of people and nature. These emerging themes have the potential to transform management and policy approaches for protected areas and have important implications for conservation, in both theory and practice. © 2017 by the Ecological Society of America.

  12. Ecological niche of family farmers in southern Minas Gerais state (Brazil

    Directory of Open Access Journals (Sweden)

    M. M. Cavallini

    Full Text Available The concept of ecological niche, considered by the food dimension point of view, was used to characterize a small farmers community from the south of Minas Gerais State (Brazil. Ten small farmer families and 76 different meals eaten by them were evaluated in this study, during three different periods: September 1995 (end of the dry season, December 1995 (rainy season and April 1996 (end of the rainy season. The analysed community appeared to depend markedly on certain food items showing little seasonal variation in their diet and appeared also to be self-sufficient in food supply, with satisfactory nutritional status. The food niche breadth for the studied small farmer families was always below 50%, with high seasonal overlap of the food niche, around 72% to 80%. The results are discussed based on social-cultural, economical and agrarian context.

    Pušić Ljubinko

    2006-01-01

    Full Text Available This paper discusses the general problem of territorialization and the special problems of cultural-genetical conditions in the sociological construction of social capital. The starting base is presented by the fact that a connection between the social-ecological conditions of an environment and social capital is historical, permanent and crucial. High and continuous growing level of urbanization in Vojvodina shows the prevailing of urban society inside of which the social capital is being formed. However, in the conditions of social transition also appear controversial relations which exert influence on the creation and functioning of social capital. Social-economical structure of the urban population in Vojvodina and the governing systems of values do not necessary product also the urban way of life, which therefore exerts influence on the quality of social capital. In this paper is particularly examined a connection of the spatial mobility of the urban population, institutional channels and local conditions in the social construction of social capital.

  3. Putting the "E" in SES: unpacking the ecology in the Ostrom social-ecological system framework

    Directory of Open Access Journals (Sweden)

    Jessica M. Vogt

    2015-03-01

    Full Text Available The Ostrom social-ecological system (SES framework offers an interdisciplinary tool for studies of linked human-natural systems. However, its origin in the social sciences belies the effectiveness of its interdisciplinary ambitions and undermines its ability to cope with ecological complexity. To narrow the gap between inherently dynamic ecological systems and the SES framework, we need to explicitly recognize that SES outcomes are coproduced by social systems in which choices are made, as well as an ecological system with a diverse assortment of dynamic natural processes that mediate the effect of those choices. We illustrate the need for more explicit incorporation of ecological attributes into the SES framework by presenting a case study of a community-managed forest in Indiana, USA. A preliminary set of ecological attributes are also proposed for inclusion in the SES framework with the aim of spurring interest in further development of a truly interdisciplinary framework for the study of SESs.

  5. Challenges for Social-Ecological Transformations: Contributions from Social and Political Ecology

    Directory of Open Access Journals (Sweden)

    Christoph Görg

    2017-06-01

    Full Text Available Transformation has become a major topic of sustainability research. This opens up new perspectives, but at the same time, runs the danger to convert into a new critical orthodoxy which narrows down analytical perspectives. Most research is committed towards a political-strategic approach towards transformation. This focus, however, clashes with ongoing transformation processes towards un-sustainability. The paper presents cornerstones of an integrative approach to social-ecological transformations (SET, which builds upon empirical work and conceptual considerations from Social Ecology and Political Ecology. We argue that a critical understanding of the challenges for societal transformations can be advanced by focusing on the interdependencies between societies and the natural environment. This starting point provides a more realistic understanding of the societal and biophysical constraints of sustainability transformations by emphasising the crisis-driven and contested character of the appropriation of nature and the power relations involved. Moreover, it pursues a transdisciplinary mode of research, decisive for adequately understanding any strategy for transformations towards sustainability. Such a conceptual approach of SET is supposed to better integrate the analytical, normative and political-strategic dimension of transformation research. We use the examples of global land use patterns, neo-extractivism in Latin America and the global water crisis to clarify our approach.

  6. Public health and social ideas in modern Brazil.

    Lima, Nísia Trindade

    2007-07-01

    Public health in Brazil achieved remarkable development at the turn of the 20th century thanks in part to physicians and social thinkers who made it central to their proposals for "modernizing" the country. Public health was more than a set of medical and technical measures; it was fundamental to the project of nation building. I trace the interplay between public health and social ideas in the late 19th and early 20th centuries. Physicians and social thinkers challenged the traditional belief that Brazil's sociocultural and ethnic diversity was an obstacle to modernization, and they promoted public health as the best prescription for national unity. Public health ideas in developing countries such as Brazil may have a greater impact when they are intertwined with social thought and with the processes of nation building and construction of a modern society.

    2015-12-01

    Full Text Available The development of targets is foundational in conservation. Although progress has been made in setting targets, the diverse linkages among ecological and social components make target setting for coupled social-ecological systems extremely challenging. Developing integrated social-ecological targets is difficult because it forces policy makers to consider how management actions propagate throughout social-ecological systems, and because ultimately it is society, not scientists, that defines targets. We developed an interdisciplinary approach for identifying management targets and illustrate this approach using an example motivated by Puget Sound, USA. Our approach blends ecological modeling with empirical social science to articulate trade-offs and reveal societal preferences for different social-ecological states. The framework aims to place information in the hands of decision makers and promote discussion in the appropriate forums. Our ultimate objective is to encourage the informed participation of citizens in the development of social-ecological targets that reflect their values while also protecting key ecosystem attributes.

  8. Our Social Roots: How Local Ecology Shapes Our Social Structures

    Science.gov (United States)

    Mace, Ruth

    There is overwhelming evidence that wide-ranging aspects of human biology and human behavior can be considered as adaptations to different subsistence systems. Wider environmental and ecological correlates of behavioral and cultural traits are generally best understood as being mediated by differences in subsistence strategies. Modes of subsistence profoundly influence both human biology, as documented in genetic changes, and human social behavior and cultural norms, such as kinship, marriage, descent, wealth inheritance, and political systems. Thus both cultural and biological factors usually need to be considered together in studies of human evolutionary ecology, combined in specifically defined evolutionary models. Models of cultural adaptation to environmental conditions can be subjected to the same or similar tests that behavioral ecologists have used to seek evidence for adaptive behavior in other species. Phylogenetic comparative methods are proving useful, both for studying co-evolutionary hypotheses (cultural and/or gene-culture co-evolution), and for estimating ancestral states of prehistoric societies. This form of formal cross-cultural comparison is helping to put history back into anthropology, and helping us to understand cultural evolutionary processes at a number of levels.

    2010-09-01

    Full Text Available This article represents the first ethnospongiological study in Brazil, and it aimed at recording artisanal fishermen’s knowledge about sea sponges and their ecological interactions. The study was carried out in the Ilha do Contrato community at Camamu Bay, Bahia State, Brazil. The data were obtained by means of open-ended interviews and projective tests, and followed the usual techniques of ethnographic surveys. The interviewees had knowledge regarding ecological interactions among fish, sea sponges and sponge endofaunal composition. According to the results, there is some congruence between folk wisdom and scientific knowledge. The importance of integrating local knowledge into management and conservation plans designed for the Camamu Bay region, as well as the set of data on ecology of reef communities, should be considered.

    To identify social ecological correlates of objectively measured workplace sedentary behavior. Participants from 24 worksites - across academic, industrial, and government sectors - wore an activPAL-micro accelerometer for 7-days (Jan-Nov 2016). Work time was segmented using daily logs. Sedentary behavior outcomes included time spent sitting, standing, in light intensity physical activity (LPA, stepping cadence 30 min). Outcomes were standardized to an 8 h work day. Two electronic surveys were completed to derive individual (job type and work engagement), cultural (lunch away from the desk, walking at lunch and face-to-face interaction), physical (personal printer and office type) and organizational (sector) factors. Mixed-model analyses with worksite-level clustering were performed to examine multi-level associations. Secondary analyses examined job type and sector as moderators of these associations. All models were adjusted for age, race/ethnicity and gender. Participants (N = 478; 72% female; age: 45.0 ± 11.3 years; 77.8% non-Hispanic white) wore the activPAL-micro for 90.2 ± 15.5% of the reported workday. Walking at lunch was positively associated with LPA (5.0 ± 0.5 min/8 h, P workplace sedentary behavior. Associations vary by job type and sector and should be considered in the design of workplace interventions to reduce sedentary behavior. Clinical trial No. NCT02566317 ; Registered Sept 22nd 2015.

    2017-07-17

    An overarching challenge of natural resource management and biodiversity conservation is that relationships between people and nature are difficult to integrate into tools that can effectively guide decision making. Social-ecological vulnerability offers a valuable framework for identifying and understanding important social-ecological linkages, and the implications of dependencies and other feedback loops in the system. Unfortunately, its implementation at local scales has hitherto been limited due at least in part to the lack of operational tools for spatial representation of social-ecological vulnerability. We developed a method to map social-ecological vulnerability based on information on human-nature dependencies and ecosystem services at local scales. We applied our method to the small-scale fishery of Moorea, French Polynesia, by combining spatially explicit indicators of exposure, sensitivity, and adaptive capacity of both the resource (i.e., vulnerability of reef fish assemblages to fishing) and resource users (i.e., vulnerability of fishing households to the loss of fishing opportunity). Our results revealed that both social and ecological vulnerabilities varied considerably through space and highlighted areas where sources of vulnerability were high for both social and ecological subsystems (i.e., social-ecological vulnerability hotspots) and thus of high priority for management intervention. Our approach can be used to inform decisions about where biodiversity conservation strategies are likely to be more effective and how social impacts from policy decisions can be minimized. It provides a new perspective on human-nature linkages that can help guide sustainability management at local scales; delivers insights distinct from those provided by emphasis on a single vulnerability component (e.g., exposure); and demonstrates the feasibility and value of operationalizing the social-ecological vulnerability framework for policy, planning, and participatory

  13. Graduate students navigating social-ecological research: insights from the Long-Term Ecological Research Network

    Directory of Open Access Journals (Sweden)

    Sydne Record

    2016-03-01

    Full Text Available Interdisciplinary, collaborative research capable of capturing the feedbacks between biophysical and social systems can improve the capacity for sustainable environmental decision making. Networks of researchers provide unique opportunities to foster social-ecological inquiry. Although insights into interdisciplinary research have been discussed elsewhere, they rarely address the role of networks and often come from the perspectives of more senior scientists. We have provided graduate student perspectives on interdisciplinary degree paths from within the Long-Term Ecological Research (LTER Network. Focusing on data from a survey of graduate students in the LTER Network and four self-identified successful graduate student research experiences, we examined the importance of funding, pedagogy, research design and development, communication, networking, and culture and attitude to students pursuing social-ecological research. Through sharing insights from successful graduate student approaches to social-ecological research within the LTER Network, we hope to facilitate dialogue between students, faculty, and networks to improve training for interdisciplinary scientists.

    2014-10-01

    To analyse the ecological association between the demographic and socio-economic characteristics of the Brazilian municipalities and average leprosy incidence rate in the period 2009-2011. An ecological study taking the Brazilian municipalities as its units of analysis. The local empirical Bayes estimation method was used to obtain smoothed incidence rates (SIR) for leprosy. The mean, median, first quartile (Q1) and third quartile (Q3) of the SIR were calculated per 100 000 inhabitants. Hierarchical log-linear negative binomial regression models were used to estimate the incidence rate ratios (IRR). In the period 2009-2011, the average SIR of leprosy in Brazil was 20.2 per 100 000 inhabitants, and the median incidence rate among municipalities was 9.1 per 100 000 inhabitants. Significantly higher adjusted IRR were identified for large municipalities (IRR = 1.67) compared to small municipalities, as well as in municipalities with higher illiteracy rates (IRR = 2.15), more urbanised municipalities (IRR = 1.53), those with greater social inequality as per the Gini index (IRR = 1.26), high percentage of households with inadequate sanitation (IRR = 1.63), higher average number of people per room (IRR = 1.41), high proportions of Family Health Programme coverage (IRR = 1.29), high percentage of household contacts investigated (IRR = 2.30) and those with percentage of cases with grade 2 disability considered to be the medium (IRR = 1.26). In this study, SIR was significantly associated with municipalities with low socio-economic status. Disease control activities need to be focused on these municipalities, and investments need to be made in improving the population's living conditions. © 2014 John Wiley & Sons Ltd.

    Schütz, Gabriel Eduardo; Mello, Marcia Gomide da Silva; de Carvalho, Marcia Aparecida Ribeiro; Câmara, Volney de Magalhães

    2014-10-01

    The scope of this article is to apply a trans-disciplinary socio-ecological approach to discuss the super-determination of health in rural areas of the southern Amazon region from a case study developed in Humaitá in the State of Amazonas in Brazil. Field data were collected using ethnographic techniques applied during three expeditions in Humaitá's rural area between 2012 and 2014. Based on the 'socio-ecological metabolism' analytical category, a descriptive and theoretical analysis of four crucial components in the process of super-determination of local health are presented: (1) the composition of the local rural population; (2) fixed and changing territorial aspects; (3) construction of socio-ecological identities; (4) ethnic conflict between Indians and non-Indians. The conclusion reached is that the incorporation of a socio-ecological approach in territorial-based health research provides input for analyses of the local health situation through the systematization of information related to the process of super-determination of health. It also helps in the construction of trans-disciplinarity, which is a necessary epistemological condition for addressing the complex reality at the interfaces of social production, the environment and health.

  1. Ecology and conservation of dusky grouper (Epinephelidae in southern Brazil

    Directory of Open Access Journals (Sweden)

    Mario Vinicius Condini

    2015-11-01

    Full Text Available The dusky grouper Epinephelus marginatus has a broad global distribution and is currently listed as an endangered species at the IUCN Red List. This species has large commercial and ecological importance, but only at the last decade the first studies were carried out on its bioecology at its southernmost distribution limit in Southwestern Atlantic. This region is largely formed by sand bottoms, where the occurrence of reefs and rocks are scarce. Rocky bottoms occur in the neritic region (along 20 to 30 m isobaths and in the jetties in the littoral region, and in both areas the dusky grouper occur frequently. Our studies showed that immature individuals (mean: 4 yrs of dusky groupers inhabiting rocky jetties in the littoral region represents an important economical incoming for artisanal fishermen, whereas adults (mean: 8 yrs are mostly caught at offshore banks 15-25 m deep by coastal fisheries. Microscopic analyses of gonads of littoral and neritic individuals suggest that the littoral region is a growing nursery area and the neritic is a reproductive site. Feeding ecology studies based on stomach content and stable isotopes showed that the species has an important role as top predators in both regions. Future studies on the residence time of immature individuals in the littoral using telemetry are fundamental to further understand the ecology of this endangered species in the Southwestern Atlantic and to help its fishing management and conservation.

    2015-12-01

    Full Text Available In this article the marketing role in a sustainable development of territories and the solution of problems of environmental protection is proved, lack of difficult integration of concept ecological and place marketing on micro- and mesolevels is established. The comparative analysis of approaches to the formation of a conceptual basis of the theory of social and ecological systems as the methodological basis of ecological place marketing is carried out. The braking factors of the formulation of the definitions of monoaspect describing interaction of supersystems of the nature, society and the economy connected with difficulty of their universal use in research of other disciplinary or interdisciplinary profile are assigned. It is expedient to use institutional evolutionary E. Ostrom’s approach to interpretation of social and ecological systems. It is proved that such systems are characterized by the increased level of system integration and interdependence of their elements which are difficult for decomposition into separate objects of management; domination of informal institutes and heterogeneity of institutional structure which determines the high level of uncertainty and operational expenses, congenital from them. The author assigned the methodological principles of the marketing analysis of the social and ecological systems founded on the principles of a continuity of social and natural processes, heterogeneity of a subject and structure of object, an economic causal relationship, stakeholdering, evolutionary character and transformation of the market of the social and ecological relations.

    Cumming, Graeme S; Peterson, Garry D

    2017-09-01

    Ecosystems influence human societies, leading people to manage ecosystems for human benefit. Poor environmental management can lead to reduced ecological resilience and social-ecological collapse. We review research on resilience and collapse across different systems and propose a unifying social-ecological framework based on (i) a clear definition of system identity; (ii) the use of quantitative thresholds to define collapse; (iii) relating collapse processes to system structure; and (iv) explicit comparison of alternative hypotheses and models of collapse. Analysis of 17 representative cases identified 14 mechanisms, in five classes, that explain social-ecological collapse. System structure influences the kind of collapse a system may experience. Mechanistic theories of collapse that unite structure and process can make fundamental contributions to solving global environmental problems. Copyright © 2017. Published by Elsevier Ltd.

  4. Ecological psychology and social psychology: it is Holt, or nothing!

    Science.gov (United States)

    Charles, Eric P

    2011-03-01

    What is the greatest contribution that ecological psychologists can offer social psychology? Ideally, ecological psychologists could explain how people directly perceive the unique properties of their social partners. But social partners are distinguished from mundane objects because they possess mental traits, and tradition tells us that minds cannot be seen. When considering the ideal possibility, we reject that doctrine and posit minds as perceivable. For ecological psychology, this entails asserting that minds are the types of things able to structure ambient energy. Contemporary research and theory suggests distinctly ecological ways of attacking this problem, but the problem is not new. Almost 100 years ago, Holt argued for the visibility of minds. Thus when considering these ideas, ecological psychologists face a choice that is at once about their future and their past. Extending ecological psychology's first principles into the social realm, we come to the point where we must either accept or reject Holt's arguments, and the wider context they bring. In doing so, we accept or reject our ability to study the uniquely social.

    Manfredo, Michael J.; Teel, Tara L.; Gavin, Michael C.; Fulton, David C.

    2017-01-01

    In this chapter we focus on how to integrate the human individual into social-ecological systems analysis, and how to improve research on individual thought and action regarding the environment by locating it within the broader social-ecological context. We discuss three key questions as considerations for future research: (1) is human thought conceptualized as a dynamic and adaptive process, (2) is the individual placed in a multi-level context (including within-person levels, person-group interactions, and institutional and structural factors), and (3) is human thought seen as mutually constructed with the social and natural environment. Increased emphasis on the individual will be essential if we are to understand agency, innovation, and adaptation in social-ecological systems.

    In this study we analyze population dynamics of hantavirus rodent hosts and prevalence of infection over a 2-year period in Southern Brazil, a region with a high incidence of hantavirus pulmonary syndrome. The 14 small mammal species captured were composed of 10 rodents and four marsupials, the six most abundant species being Akodon serrensis, Oxymycterus judex, Akodon montensis, Akodon paranaensis, Oligoryzomys nigripes, and Thaptomys nigrita. These species displayed a similar pattern with increasing population sizes in fall/winter caused by recruitment and both, increase in reproductive activity and higher hantavirus prevalence in spring/summer. Specific associations between A. montensis/Jaborá Virus (JABV) and O. nigripes/Juquitiba-like Virus (JUQV-like) and spillover infections between A. paranaensis/JABV, A. serrensis/JABV, and A. paranaensis/JUQV-like were observed. Spillover infection in secondary hosts seems to play an important role in maintaining JABV and JUQV-like in the hantavirus sylvatic cycle mainly during periods of low prevalence in primary hosts.

    Full Text Available ABSTRACT The feeding ecology of five elasmobranch species was studied on the southern coast of Rio de Janeiro, southwestern Atlantic Ocean. The specimens were caught with a trawl or bottom longline between January 2006 and August 2007. The diets of Psammobatis rutrum and Psammobatis extenta appeared to be basically carcino-benthophagous, with a very small niche width. Rioraja agassizii was basically carcino/ichthyo-benthophagous, also with a narrow niche, including teleost fish and shrimp, but in different proportions according to age and sex. Rhizoprionodon lalandii was ichthyophagous, not influenced by age or sex. The analyses of these species and Atlantoraja cyclophora indicated two trophic groups: one composed of the smaller rays, P. extenta and P. rutrum, which basically fed on small crustaceans, polychaetes and nematodes; and the other of R. lalandii and the larger rays R. agassizii and A. cyclophora, which preyed on teleost fish and brachyurans.

    Conservation and environmental management are principal countermeasures to the degradation of marine ecosystems and their services. However, in many cases, current practices are insufficient to reverse ecosystem declines. We suggest that restoration ecology, the science underlying the concepts and tools needed to restore ecosystems, must be recognized as an integral element for marine conservation and environmental management. Marine restoration ecology is a young scientific discipline, often with gaps between its application and the supporting science. Bridging these gaps is essential to using restoration as an effective management tool and reversing the decline of marine ecosystems and their services. Ecological restoration should address objectives that include improved ecosystem services, and it therefore should encompass social-ecological elements rather than focusing solely on ecological parameters. We recommend using existing management frameworks to identify clear restoration targets, to apply quantitative tools for assessment, and to make the re-establishment of ecosystem services a criterion for success.

    2014-01-01

    Environmental law envisions ecological systems as existing in an equilibrium state, reinforcing a rigid legal framework unable to absorb rapid environmental changes and innovations in sustainability. For the past four decades, “resilience theory,” which embraces uncertainty and nonlinear dynamics in complex adaptive systems, has provided a robust, invaluable foundation for sound environmental management. Reforming American law to incorporate this knowledge is the key to sustainability. This volume features top legal and resilience scholars speaking on resilience theory and its legal applications to climate change, biodiversity, national parks, and water law.

  15. Social affordances and the possibility of ecological linguistics.

    Kono, Tetsuya

    2009-12-01

    This paper includes an effort to extend the notion of affordance from a philosophical point of view the importance of ecological approach for social psychology, ethics, and linguistics. Affordances are not always merely physical but also interpersonal and social. I will conceptualize affordance in general and social affordance in particular, and will elucidate the relation between intentional action and affordances, and that between affordances and free will. I will also focus on the relation between social institution and affordance. An extended theory of affordances can provide a way to analyze in concrete ways how social institution works as an implicit background of interpersonal interactions. Ecological approach considers social institution as the producer and maintainer of affordances. Social institutions construct the niches for human beings. Finally, I will argue the possibility of the ecological linguistics. Language is a social institution. The system of signs is the way to articulate and differentiate interpersonal affordances. Language acquires its meaning, i.e. communicative power in the interpersonal interactions, and interpersonal interactions, in turn, develop and are elaborated through the usage of signs. Communication is seen as never aimed to transmit inner ideas to others, but to guide and adjust the behaviors of others thorough articulating the affordance of responsible-ness.

  16. Developmental change in social responsibility during adolescence: An ecological perspective.

    2016-01-01

    Social responsibility can be defined as a set of prosocial values representing personal commitments to contribute to community and society. Little is known about developmental change-and predictors of that change-in social responsibility during adolescence. The present study used an accelerated longitudinal research design to investigate the developmental trajectory of social responsibility values and ecological assets across family, school, community, and peer settings that predict these values. Data come from a 3-year study of 3,683 U.S. adolescents enrolled in upper-level elementary, middle, and high schools in rural, semiurban, and urban communities. Social responsibility values significantly decreased from age 9 to 16 before leveling off in later adolescence. Family compassion messages and democratic climate, school solidarity, community connectedness, and trusted friendship, positively predicted within-person change in adolescents' social responsibility values. These findings held after accounting for other individual-level and demographic factors and provide support for the role of ecological assets in adolescents' social responsibility development. In addition, fair society beliefs and volunteer experience had positive between- and within-person associations with social responsibility values. The manuscript discusses theoretical and practical implications of the conclusion that declines in ecological assets may partly explain age-related declines in social responsibility values.

    Most assessments of resilience have been focused on local conditions. Studies focused on the relationship between humanity and environmental degradation are rare, and are rarely comprehensive. We investigated multiple social-ecological factors for 100 countries around the globe in relation to the percentage of invasions and extinctions within each country. These 100 countries contain approximately 87% of the world’s population, produce 43% of the world’s per capita gross domestic product (GDP), and take up 74% of the earth’s total land area. We used an information theoretic approach to determine which models were most supported by our data, utilizing an a priori set of plausible models that included a combination of 15 social-ecological variables, each social-ecological factor by itself, and selected social-ecological factors grouped into three broad classes. These variables were per capita GDP, export-import ratio, tourism, undernourishment, energy efficiency, agricultural intensity, rainfall, water stress, wilderness protection, total biodiversity, life expectancy, adult literacy, pesticide regulation, political stability, and female participation in government. Our results indicate that as total biodiversity and total land area increase, the percentage of endangered birds also increases. As the independent variables (agricultural intensity, rainfall, water stress, and total biodiversity) in the ecological class model increase, the percentage of endangered mammals in a country increases. The percentage of invasive birds and mammals in a country increases as per capita GDP increases. As life expectancy increases, the percentage of invasive and endangered birds and mammals increases. Although our analysis does not determine mechanisms, the patterns observed in this study provide insight into the dynamics of a complex, global, social-ecological system.

  1. Local ecological knowledge on the goliath grouper epinephelus itajara (teleostei: serranidae in southern Brazil

    Leopoldo Cavaleri Gerhardinger

    Full Text Available The goliath grouper Epinephelus itajara is a large sized (> 400 kg and critically endangered marine fish, which is protected in many countries, including Brazil. Through the application of semi-structured interviews, we investigated the local ecological knowledge of seven fishermen specialist on catching E. itajara from the Babitonga bay, Santa Catarina, Brazil. Local long-line fisheries for E. itajara seemed to be a disappearing tradition in the studied site, with a detailed inherent local ecological knowledge system, which is also being lost. Our study also showed that fishermen engaged in recent fisheries, such as spear-fishing, can also possess a detailed local ecological knowledge system. Through the analysis of fishermen local ecological knowledge, several aspects of E. itajara life history were registered. This species is found in the inner and outer Babitonga bay, from saline waters to areas with a large input of freshwater, and inhabits submerged wooden substrates and artificial reefs such as shipwrecks, mooring pillars and cargo containers. It is known to spawn in December and subsequent summer months in the studied area. Spawning aggregations are usually seen in December (during full moon, being also eventually observed in January and February by our informants. While lobsters, spadefishes and octopuses seem to constitute the most important food items of inner bay E. itajara, outer bay individuals may feed on catfishes, crustaceans and other fish species. The goliath grouper is regarded as pacific and curious fish, but frequently display agonistic behavior in the presence of divers. Based on the perception of well experienced spear fishermen, we hypothesize that E. itajara undertakes seasonal migrations from the inner to the outer bay during summer, and that the studied population is suffering from growth over-fishing. Our data provides a practical evidence of how joining scientific and local ecological knowledge will likely benefit E

    2014-06-01

    Relational and social network perspectives provide opportunities for more holistic conceptualizations of phenomena of interest in community psychology, including power and empowerment. In this article, we apply these tools to build on multilevel frameworks of empowerment by proposing that networks of relationships between individuals constitute the connective spaces between ecological systems. Drawing on an example of a model for grassroots community organizing practiced by WISDOM—a statewide federation supporting local community organizing initiatives in Wisconsin—we identify social regularities (i.e., relational and temporal patterns) that promote empowerment and the development and exercise of social power through building and altering relational ties. Through an emphasis on listening-focused one-to-one meetings, reflection, and social analysis, WISDOM organizing initiatives construct and reinforce social regularities that develop social power in the organizing initiatives and advance psychological empowerment among participant leaders in organizing. These patterns are established by organizationally driven brokerage and mobilization of interpersonal ties, some of which span ecological systems.Hence, elements of these power-focused social regularities can be conceptualized as cross-system channels through which micro-level empowerment processes feed into macro-level exercise of social power, and vice versa. We describe examples of these channels in action, and offer recommendations for theory and design of future action research [corrected] .

  5. Social Movements in Brazil and their Educational Work

    Ghanem, Elie

    1998-03-01

    Using a distinction first proposed by Alain Touraine between historic and social movements, Ghanem's review of grassroots initiatives in Brazil argues that, despite differences in composition and aims, movements such as the landless rural workers, indigenous groups, and the women's movement in Brazil have attempted to shift the current socioeconomic order toward a new equilibrium - a process that is, however, not yet complete. In Ghanem's view, these movements are best described as historic movements. Addressing their educational aims, the author finds that they tend to fall into two types: (1) the self-provision of knowledge related to the set of problems that gave rise to their movement in the first place; (2) the striving for access to knowledge that is due to them as citizens and yet not given to them by the state. Often, social movements in Brazil are obliged to offer educational services through their own resources, services which are characterized by precarious conditions and which make the right to quality education still a distant dream.

  6. Cumulative Effects Assessment: Linking Social, Ecological, and Governance Dimensions

    Full Text Available Setting social, economic, and ecological objectives is ultimately a process of social choice informed by science. In this special feature we provide a multidisciplinary framework for the use of cumulative effects assessment in land use planning. Forest ecosystems are facing considerable challenges driven by population growth and increasing demands for resources. In a suite of case studies that span the boreal forest of Western Canada to the interior Atlantic forest of Paraguay we show how transparent and defensible methods for scenario analysis can be applied in data-limited regions and how social dimensions of land use change can be incorporated in these methods, particularly in aboriginal communities that have lived in these ecosystems for generations. The case studies explore how scenario analysis can be used to evaluate various land use options and highlight specific challenges with identifying social and ecological responses, determining thresholds and targets for land use, and integrating local and traditional knowledge in land use planning. Given that land use planning is ultimately a value-laden and often politically charged process we also provide some perspective on various collective and expert-based processes for identifying cumulative impacts and thresholds. The need for good science to inform and be informed by culturally appropriate democratic processes calls for well-planned and multifaceted approaches both to achieve an informed understanding of both residents and governments of the interactive and additive changes caused by development, and to design action agendas to influence such change at the ecological and social level.

    Anticipation is increasingly central to urgent contemporary debates, from climate change to the global economic crisis. Anticipatory practices are coming to the forefront of political, organizational, and citizens' society. Research into anticipation, however, has not kept pace with public demand for insights into anticipatory practices, their risks and uses. Where research exists, it is deeply fragmented. This paper seeks to identify how anticipation is defined and understood in the literature and to explore the role of anticipatory practice to address individual, social, and global challenges. We use a resilience lens to examine these questions. We illustrate how varying forms of anticipatory governance are enhanced by multi-scale regional networks and technologies and by the agency of individuals, drawing from an empirical case study on regional water governance of Mälaren, Sweden. Finally, we discuss how an anticipatory approach can inform adaptive institutions, decision making, strategy formation, and societal resilience.

    A number of social-ecological systems exhibit complex behaviour associated with nonlinearities, bifurcations, and interaction with stochastic drivers. These systems are often prone to abrupt and unexpected instabilities and state shifts that emerge as a discontinuous response to gradual changes in environmental drivers. Predicting such behaviours is crucial to the prevention of or preparation for unwanted regime shifts. Recent research in ecology has investigated early warning signs that anticipate the divergence of univariate ecosystem dynamics from a stable attractor. To date, leading indicators of instability in systems with multiple interacting components have remained poorly investigated. This is a major limitation in the understanding of the dynamics of complex social-ecological networks. Here, we develop a theoretical framework to demonstrate that rising variance--measured, for example, by the maximum element of the covariance matrix of the network--is an effective leading indicator of network instability. We show that its reliability and robustness depend more on the sign of the interactions within the network than the network structure or noise intensity. Mutualistic, scale free and small world networks are less stable than their antagonistic or random counterparts but their instability is more reliably predicted by this leading indicator. These results provide new advances in multidimensional early warning analysis and offer a framework to evaluate the resilience of social-ecological networks.

    Full Text Available In research on CSR in Brazil and Argentina, we saw a huge disparity in the grass-roots of the theme in each country. The hypothesis, stemming from this article, is that the great success of the CSR movement in Brazil and its relatively weak development in Argentina is due to the presence of a hegemonic dispute - in observed dynamic communication - among some segments of business elites regarding the purpose of CSR, present in the Brazilian case and absent in Argentina. This article intends to discuss the concept of hegemonic dispute - highlighting conflict as a fundamental social relationship in the configuration of network topographies of movements to promote CSR in both countries. Such an understanding is essential for professionals and researchers working in the area of ​​organizational communication.

    Scientists from the biophysical and social sciences often define resilience substantially different. Biophysical scientists primarily use resilience to understand how a system can return to an equilibrium following a perturbation, and social scientists use resilience to understand what enables, or disable, human development. In the Anthropocene, where social changes are causing both linear and nonlinear biophysical changes, with local or distant feedbacks on society, it is important to develop integrated definitions and analytical methods to analyze combined social-ecological interactions. There has been a growing amount of research in this field over the last decade, but with a primary focus on relatively small-scale regions or specific ecosystems. In this paper we review literature dealing with interdisciplinary aspects of resilience to global change and develop a conceptual framework for analyzing social-ecological resilience in relation to moisture recycling (i.e. where evaporation from land returns as precipitation on land). We first identify current social drivers of changes in evaporation (including e.g. large scale land and water acquisitions, and REDD+ programs). We then identify geographic regions where the effects of altered evaporation on moisture recycling can risk a) causing thresholds in specific biomes (such as between forests and savannas), or b) shifts in social systems (such as collapse of rainfed farming systems). We also identify institutional structures that enhance the capacity to enhance resilience through either dealing directly with drivers, or building adaptive capacity to changes in moisture recycling. We particularly stress the difference between regional feedbacks (where the consequences are felt in the same regions where decisions are made), and teleconnections, i.e. where local decision in one place is altering important drivers for distant social-ecological systems. Through this review we identify the characteristics of interlinked

    In Southeastern Brazil tilapia culture is conducted in extensive and semi-intensive flow-through earthen ponds, being water availability and flow management different in the rainy and dry seasons. In this region lettuce wastes are a potential cheap input for tilapia culture. This study examined the ecological processes developing during the rainy and dry seasons in three extensive flow-through earthen tilapia ponds fertilized with lettuce wastes. Water quality, plankton and sediment parameters were sampled monthly during a year. Factor analysis was used to identify the ecological processes occurring within the ponds and to construct a conceptual graphic model of the pond ecosystem functioning during the rainy and dry seasons. Processes related to nitrogen cycling presented differences between both seasons while processes related to phosphorus cycling did not. Ecological differences among ponds were due to effects of wind protection by surrounding vegetation, organic loading entering, tilapia density and its grazing pressure on zooplankton. Differences in tilapia growth among ponds were related to stocking density and ecological process affecting tilapia food availability and intraspecific competition. Lettuce wastes addition into the ponds did not produce negative effects, thus this practice may be considered a disposal option and a low-cost input source for tilapia, at least at the amounts applied in this study.

  14. Reconnecting Social and Ecological Resilience in Salmon Ecosystems

    Daniel L. Bottom

    2009-06-01

    Full Text Available Fishery management programs designed to control Pacific salmon (Oncorhynchus spp. for optimum production have failed to prevent widespread fish population decline and have caused greater uncertainty for salmon, their ecosystems, and the people who depend upon them. In this special feature introduction, we explore several key attributes of ecosystem resilience that have been overlooked by traditional salmon management approaches. The dynamics of salmon ecosystems involve social-ecological interactions across multiple scales that create difficult mismatches with the many jurisdictions that manage fisheries and other natural resources. Of particular importance to ecosystem resilience are large-scale shifts in oceanic and climatic regimes or in global economic conditions that unpredictably alter social and ecological systems. Past management actions that did not account for such changes have undermined salmon population resilience and increased the risk of irreversible regime shifts in salmon ecosystems. Because salmon convey important provisioning, cultural, and supporting services to their local watersheds, widespread population decline has undermined both human well-being and ecosystem resilience. Strengthening resilience will require expanding habitat opportunities for salmon populations to express their maximum life-history variation. Such actions also may benefit the "response diversity" of local communities by expanding the opportunities for people to express diverse social and economic values. Reestablishing social-ecological connections in salmon ecosystems will provide important ecosystem services, including those that depend on clean water, ample stream flows, functional wetlands and floodplains, intact riparian systems, and abundant fish populations.

    2012-12-01

    Full Text Available Coral reefs are among the most diverse ecosystems on the planet but are declining because of human activities. Despite general recognition of the human role in the plight of coral reefs, the vast majority of research focuses on the ecological rather than the human dimensions of reef ecosystems, limiting our understanding of social relationships with these environments as well as potential solutions for reef recovery. General frameworks for social-ecological systems (SESs have been advanced, but system-specific approaches are needed to develop a more nuanced view of human-environmental interactions for specific contexts and resource systems, and at specific scales. We synthesize existing concepts related to SESs and present a human dimensions framework that explores the linkages between social system structural traits, human activities, ecosystem services, and human well-being in coral reef SESs. Key features of the framework include social-ecological reciprocity, proximate and underlying dimensions, and the directionality of key relationships and feedback loops. Such frameworks are needed if human dimensions research is to be more fully integrated into studies of ecosystem change and the sustainability of linked SESs.

    Full Text Available Humanity has emerged as a major force in the operation of the biosphere. The focus is shifting from the environment as externality to the biosphere as precondition for social justice, economic development, and sustainability. In this article, we exemplify the intertwined nature of social-ecological systems and emphasize that they operate within, and as embedded parts of the biosphere and as such coevolve with and depend on it. We regard social-ecological systems as complex adaptive systems and use a social-ecological resilience approach as a lens to address and understand their dynamics. We raise the challenge of stewardship of development in concert with the biosphere for people in diverse contexts and places as critical for long-term sustainability and dignity in human relations. Biosphere stewardship is essential, in the globalized world of interactions with the Earth system, to sustain and enhance our life-supporting environment for human well-being and future human development on Earth, hence, the need to reconnect development to the biosphere foundation and the need for a biosphere-based sustainability science.

    Knowledge of the fauna composition of anopheline mosquitoes, their ecological aspects and behavior, and influence of climatic variables on their population dynamics can help in understanding the transmission of Plasmodium parasites and thus develop more efficient strategies for the control of malaria. In the Central Atlantic Forest Biodiversity Corridor, southeastern Brazil, foci of introduced malaria have been reported among people returning from the Amazon region, north Brazil. Our objective was to evaluate and compare the anopheline fauna from a preserved environment and an adjacent peridomiciliary modified environment at the Central Atlantic Forest Biodiversity Corridor. We collected anopheline mosquitoes on a monthly basis from June 2004 to May 2006 from both these environments to understand the ecological aspects and their association with the occurrence of malaria. We captured 5,491 anopheline mosquitoes belonging to two subgenera and 11 species and studied the correlations between anopheline mosquito species and climatic variables. We considered Anopheles darlingi (Root) as the principal malaria vector and Anopheles albitarsis s. l. (Arribalzaga) as the secondary vector.

    Social capital is an important resource that can be mobilized for purposive action or competitive gain. The distribution of social capital in social-ecological systems can determine who is more productive at extracting ecological resources and who emerges as influential in guiding their management, thereby empowering some while disempowering others. Despite its importance, the factors that contribute to variation in social capital among individuals have not been widely studied. We adopt a network perspective to examine what determines social capital among individuals in social-ecological systems. We begin by identifying network measures of social capital relevant for individuals in this context, and review existing evidence concerning their determinants. Using a complete social network dataset from Hawaii's longline fishery, we employ social network analysis and other statistical methods to empirically estimate these measures and determine the extent to which individual stakeholder attributes explain variation within them. We find that ethnicity is the strongest predictor of social capital. Measures of human capital (i.e., education, experience), years living in the community, and information-sharing attitudes are also important. Surprisingly, we find that when controlling for other factors, industry leaders and formal fishery representatives are generally not well connected. Our results offer new quantitative insights on the relationship between stakeholder diversity, social networks, and social capital in a coupled social-ecological system, which can aid in identifying barriers and opportunities for action to overcome resource management problems. Our results also have implications for achieving resource governance that is not only ecologically and economically sustainable, but also equitable.

    Dusky grouper (garoupa, Epinephelus marginatus) is an important catch for several artisanal small-scale fisheries along the Brazilian coast. It is a sedentary, monandric, and late maturing protogynous species, which makes it vulnerable to overharvesting even though it is mainly caught through hook and line or spear fishing through free diving. Lack of information on the ecology and biology of this species in Brazil is astonishing. Much of the information found in the literature concerns Mediterranean dusky groupers. Studies compiling local knowledge (ethnoecology) about fish species complement biological data, and have been fundamental for effective fisheries management. In this study, our objectives are to obtain data about dusky grouper through fish catches and analysis of stomach contents and gonad maturation (macroscopic analyses), along with interviews from fishermen from six small-scales communities from the southern (Pântano do Sul, Florianópolis, Santa Catarina State) to the northern Brazilian coast (Porto Sauípe, Bahia State). We conclude that precautionary approaches and 'data-less' management approaches are needed in the coast of Brazil. Research on this species and on the potential of aquaculture for its cultivation, are urgent, due to the apparent vulnerability and decrease of dusky grouper along the coast of Brazil.

    Full Text Available Abstract Dusky grouper (garoupa, Epinephelus marginatus is an important catch for several artisanal small-scale fisheries along the Brazilian coast. It is a sedentary, monandric, and late maturing protogynous species, which makes it vulnerable to overharvesting even though it is mainly caught through hook and line or spear fishing through free diving. Lack of information on the ecology and biology of this species in Brazil is astonishing. Much of the information found in the literature concerns Mediterranean dusky groupers. Studies compiling local knowledge (ethnoecology about fish species complement biological data, and have been fundamental for effective fisheries management. In this study, our objectives are to obtain data about dusky grouper through fish catches and analysis of stomach contents and gonad maturation (macroscopic analyses, along with interviews from fishermen from six small-scales communities from the southern (Pântano do Sul, Florianópolis, Santa Catarina State to the northern Brazilian coast (Porto Sauípe, Bahia State. We conclude that precautionary approaches and 'data-less' management approaches are needed in the coast of Brazil. Research on this species and on the potential of aquaculture for its cultivation, are urgent, due to the apparent vulnerability and decrease of dusky grouper along the coast of Brazil.

    The Tucurui Dam, which blocked the Tocantins River in 1984 in Brazil's eastern Amazonian state of Para, is a continuing source of controversy. Most benefits of the power go to aluminum smelting companies, where only a tiny amount of employment is generated. Often presented by authorities as a model for hydroelectric development because of the substantial power that it produces, the project's social and environmental impacts are also substantial. Examination of Tucurui reveals a systematic overestimation of benefits and underestimation of impacts as presented by authorities. Tucurui offers many as-yet unlearned lessons for hydroelectric development in Amazonia.

    The concept of resilience has evolved considerably since Holling's (1973) seminal paper. Different interpretations of what is meant by resilience, however, cause confusion. Resilience of a system needs to be considered in terms of the attributes that govern the system's dynamics. Three related attributes of social-ecological systems (SESs) determine their future trajectories: resilience, adaptability, and transformability. Resilience (the capacity of a system to absorb disturbance and reorgan...

    Full Text Available Spotted-fever caused Rickettsia rickettsii infection is in Brazil the major tick-borne zoonotic disease. Recently a second and milder human rickettsiosis caused by an agent genetically related to R. parkeri was discovered in the country (Atlantic rainforest strain. Both diseases clearly have an ecological background linked to a few tick species and their environment. Capybaras (Hydrochoerys hydrochaeris and Amblyomma cajennense ticks in urban and rural areas close to water sources are the main and long known epidemiological feature behind R. rickettsii caused spotted fever. Unfortunately this ecological background seems to be increasing in the country and disease spreading may be foreseen. Metropolitan area of São Paulo, the most populous of the country, is embedded in Atlantic rainforest that harbors another important R. rickettsii vector, the tick Amblyomma aureolatum. Thus at the city-forest interface dogs carry infected ticks to human dwellings and human infection occurs. A role for R. rickettsii vectoring to humans of a third tick species, Rhipicephalus sanguineus in Brazil, has not been proven; however, there is circumstantial evidence for that. A Rickettsia parkeri-like strain was found in Amblyomma ovale ticks from Atlantic rainforest, and was shown to be responsible for a milder febrile human disease. Rickettsia-infected A. ovale ticks are known to be spread over large areas along the Atlantic coast of the country and diagnosis of human infection is increasing with awareness and proper diagnostic tools. In this review ecological features of the tick species mentioned, and that are important for Rickettsia transmission to humans, are updated and discussed. Specific knowledge gaps in the epidemiology of such diseases are highlighted to guide forthcoming research.

    Full Text Available Studies on the sociality of heterospecific assemblages of birds have promoted a greater understanding of the types of interactions and survivorship between coexisting species. This study verified the group compositions in bird assemblages and analyzed the sociality of migratory and resident species on sandy beaches of southeastern Brazil. A transect was established on the median portion of beaches and all the groups of bird species (monospecific, heterospecific and solitary individuals were registered four days per month from November 2006 to April 2007. The sociality of each species was calculated by its frequency in heterospecific groups, its proportional number of contacts with other species in heterospecific groups, and the number of species that it associated with. Semipalmated Sandpiper Calidris pusilla (Linnaeus, 1766 and Semipalmated Plover Charadrius semipalmatus Bonaparte, 1825 (both migratory had the highest degree of sociality and did not show a preference to associate with either residents or migratory species. Sanderling Calidris alba (Pallas, 1764 (migratory occupied the third position in the sociality rank and associated with migratory species frequently. Southern Caracara Carara plancus (Miller, 1777 and Black Vulture Coragyps atratus (Beschstein, 1793 (both resident were uniquely found among heterospecific groups with necrophagous and resident species. Kelp Gull Larus dominicanus Lichtenstein, 1823 (resident associated more frequently with resident species. The sociality in assemblages of birds may promote advantages such as an increased collective awareness in dangerous situations and indication of sites with abundant food sources.

  6. Benefits of using a Social-Ecological Systems Approach to ...

    Science.gov (United States)

    Using a social-ecological systems (SES) perspective to examine wetland restoration helps decision-makers recognize interdependencies and relations between ecological and social components of coupled systems. Conceptual models are an invaluable tool to capture, visualize, and organize the key factors in complex social-ecological systems, but can be overwhelming to generate and lead to key concepts being overlooked if development is unstructured. Using a DPSIR approach (Drivers, Pressures, State, Impact, Responses), conceptual models can be developed to link decision scenarios and stressors to impacts on ecosystem services. These impacts on priority ecosystem services can then be linked to changes in human health and well-being through benefit functions. Expert input and contributions across disciplines provides appropriate temporal and spatial scales for determination of targets, project implementation, and monitoring strategies. This approach is being applied to create descriptive SES models of two wetland restoration projects. The first, the dredging of a degraded estuarine channel and restoration of mangrove forests in Caño Martìn Peña in San Juan, Puerto Rico is in the planning stage. The second, the restoration of a former cranberry farm in Plymouth, Massachusetts has completed a large restoration of freshwater wetland, and is gearing up for a second phase. Through the development of conceptual models, we are connecting driving forces wi

    This study makes a first attempt to operationalize the safe operating space concept at a regional scale by considering the complex dynamics (e.g. non-linearity, feedbacks, and interactions) within a systems dynamic model (SD). We employ the model to explore eight 'what if' scenarios based on well-known challenges (e.g. climate change) and current policy debates (e.g. subsidy withdrawal). The findings show that the social-ecological system in the Bangladesh delta may move beyond a safe operating space when a withdrawal of a 50% subsidy for agriculture is combined with the effects of a 2°C temperature increase and sea level rise. Further reductions in upstream river discharge in the Ganges would push the system towards a dangerous zone once a 3.5°C temperature increase was reached. The social-ecological system in Bangladesh delta may be operated within a safe space by: 1) managing feedback (e.g. by reducing production costs) and the slow biophysical variables (e.g. temperature, rainfall) to increase the long-term resilience, 2) negotiating for transboundary water resources, and 3) revising global policies (e.g. withdrawal of subsidy) that negatively impact at regional scales. This study demonstrates how the concepts of tipping points, limits to adaptations, and boundaries for sustainable development may be defined in real world social-ecological systems.

    Full Text Available Fishing has a great importance to the socioeconomic development of the Amazonian riparian communities, which have a local knowledge on the environment, its fauna and flora. This knowledge is of paramount importance for the management and conservation of fish stocks and species that interact with the fishing activity, such as the populations of gray porpoises (Sotalia sp. and pink porpoises (Inia geoffrensis. Therefore, to register local ecological knowledge and the interaction of porpoises with fishing on the coast of the state of Para, Brazil, 82 semi-structured interviews were carried out in 3 different colonies of fishermen: colony Z-1 (Soure, colony Z-7 (Maracana, and colony Z-23 (Colares. The species Sotalia sp. had a strong social structure, it can be observed in the region both during the dry and rainy seasons, while the species I. geoffrensis didn’t present a social structure, it’s observed in the region especially during the rainy season. The pink porpoise showed a larger interaction with fishing than the gray porpoise, however, this interaction was particularly detrimental to the activity, while the gray porpoise showed both a beneficial and a harmful interaction with fishing. The incidental capture of porpoises primarily occurred through nets and trawls, harming their populations. Captured animals were mostly released, however, there were records of consumption for food, use as bait, and selling of the animal’s eyes. This information will constitute the basis for further studies on the biology, ecology, and estimate of the mortality of porpoises on the Amazon coast. Management measures should be adopted, along with the communities studied, for the conservation of these animals in the region.

    Full Text Available Rural areas are facing a spectrum of landscape changes and vulnerability as a consequence of financial and environmental crises. Innovative approaches are required to maintain the provision of social services and manage ecosystem services in these areas. We explore the capacity of social farming to create viable and sustainable rural and periurban areas according to a social-ecological perspective. We use the key elements of social-ecological systems under social farming practices to analyse (1 the role of local communities and non-formal institutions; (2 the involvement of target stakeholders; and (3 the explicit connection between agroecosystems and human wellbeing. To do so, we selected and described four cases of local social farming initiatives in terms of the key elements of social-ecological systems and conducted a literature review to provide an overview of the explicit impact of social farming on the quality of life. We found that social farming illustrates hybrid governance solutions beyond market instruments that could be applied for the governance of agroecosystems. It can also provide a range of other wellbeing and cultural ecosystem services to rural and urban inhabitants. Greater cooperation between social farming and ecosystem service science could rebound in rural landscape sustainability.

  11. Social question and social work: contemporary challenges facing the profession in Brazil

    Directory of Open Access Journals (Sweden)

    Rodrigo José Teixeira

    2017-12-01

    Full Text Available This article offers an analysis of the intrinsic relationship between the social question and Social Work. The analysis of the social question starts from the meticulous and rigorous reading of the labor theory of value and the Critique of Political Economy written by Karl Marx. It is from this analysis that we try to justify the genesis of the profession linked to the role of the state and the bourgeoisie in the consolidation of monopoly capitalism. It starts from the analysis of Social Work as a profession inserted in the social and technical division of labor that by its own action, in the contradictory movement of the capitalist reality, defends the interests of capital and labor. In addition, the article presents, in a succinct way, the trajectory of Social Work in Brazil and its ethical and political project in relation to the working class challenges to guarantee this direction in times of dismantling social policies and financial capitalism.

    The article analyzes the social protection policy for people with disabilities in Brazil. It describes the patterns of demand and eligibility for Continued Benefit of Social Assistance (Benefício de Prestação Continuada - BPC) in the 1996-2014 period. The article argues that BPC is a direct result of the social pact achieved by the Brazilian Federal Constitution of 1988. BPC is a social assistance benefit consisting in an unconditional and monthly transference of the equivalent of a minimum wage, to poor people with deficiency and elders with more than 65 years. Disabled person eligibility depends on means-test, and social and medical evaluation by public bureaucracy. The research strategy was based on time series, and cross-sectional data collection and analysis. Dummy qualitative variables were also used to describe the pattern of demand and eligibility. The article demonstrates that BPC has provided income to disabled and elder people. However, systematic barriers were identified to disabled people's access to BPC. The work suggests that the pattern of refusal could be associated to a means testing application by street-level-bureaucracy. In this sense, the work draws attention to the necessary revision of street-level-bureaucracy tools and procedures to increase BPC positive discrimination.

    Objectives To investigate the association between suicide and area based measures of deprivation and social fragmentation. Design Ecological study. Setting 633 parliamentary constituencies of Great Britain as defined in 1991. Main outcome measures Age and sex specific mortality rates for suicide and all other causes for 1981-92. Results Mortality from suicide and all other causes increased with increasing Townsend deprivation score, social fragmentation score, and abstention from voting in all age and sex groups. Suicide mortality was most strongly related to social fragmentation, whereas deaths from other causes were more closely associated with Townsend score. Constituencies with absolute increases in social fragmentation and Townsend scores between 1981 and 1991 tended to have greater increases in suicide rates over the same period. The relation between change in social fragmentation and suicide was largely independent of Townsend score, whereas the association with Townsend score was generally reduced after adjustment for social fragmentation. Conclusions Suicide rates are more strongly associated with measures of social fragmentation than with poverty at a constituency level. Key messagesPlace of residence may affect health, and mortality from most common diseases tends to be higher in areas characterised by low socioeconomic positionResearch dating back over 100 years suggests that social fragmentation may influencesuicideIn the 1980s and 1990s, parliamentary constituencies with high levels of social fragmentation had high rates of suicide, independent of deprivationConstituencies with the greatest increases in social fragmentation between 1981 and 1991 also had the greatest increases in suicide rates over the same periodAny targeting of suicide prevention may be more effective if aimed at socially fragmented rather than deprived areas PMID:10521194

    2012-12-01

    Globalization's reach is rapidly extending to touch some of the most remote communities of the world, but we have yet to understand its scale and impact. On Nicaragua's previously remote Miskitu Coast, the introduction of new markets and global demand for seafood has resulted in changes in fishermen's harvest behavior manifested within the local fishery. Small-scale fisheries are a significant component in sustaining global fish trade, ensuring food security, and alleviating poverty, but because the fishermen are disperse, numerous and located in remote areas, the social and ecological dynamics of the system are poorly understood. Previous work has indicated a decline in fish abundance as a result of connection to markets, yet fishermen's response to this decline and the resulting shift in harvest strategy requires further examination. I identify the ecological and social factors that explain changes in fishermen behavior and use an innovative application of social network analysis to understand these changes. I also use interviews with fishermen and fishery-dependent surveys to measure catch and release behavior and seasonal gear use. Results demonstrate multiple cliques within a community that mitigate the response of fishermen to changes in the fishery. This research applies techniques in social science to address challenges in sustainable management of fisheries. As fisheries managers consider implementing new regulations, such as seasonal restrictions on gear, it is essential to understand not just how this might impact fish abundance, but how and why human systems respond as they do.

    2004-12-01

    Full Text Available Increasing interest in regime shifts in ecological and linked social-ecological systems (SESs has placed a strong focus on the thresholds of change. However, research into this topic has been hampered by a lack of empirical data. This paper describes a developing database established to address this need. The database is freely available and comprises a set of summarized published examples and a searchable bibliographic database of publications on the topic. Thresholds in the database are characterized in terms of a standardized set of 24 descriptors, including the variables along which they occur, the variables that change, and the factors that have driven the change. Readers are encouraged to contribute new examples. Examples range from conceptual models to empirical evidence. The former predominate in the literature and, although they make valuable contributions and will continue to be included, the intention is build up the number of examples based on data. Examples are presented in terms of whether the threshold occurs in the ecological system, the social system, or both, and the direction of interactions between systems. The paper concludes with some initial observations on thresholds based on the examples included so far, and poses some questions for future research. Research on a typology of thresholds is a priority topic in the emerging area of "sustainability science" and it requires a rich database of empirical data.

  16. Social and cultural dimensions of hypertension in Brazil: a review

    Directory of Open Access Journals (Sweden)

    Dressler William W.

    2000-01-01

    Full Text Available Elevated arterial blood pressure varies substantially in relation to social and cultural variables. Early work on acculturation, socioeconomic status, and blood pressure documented this variation, which could not be explained entirely by conventional factors such as diet, physical activity, or access to medical care. These findings stimulated the development of a model of stress and disease. The stress model emphasizes social and psychological factors that are perceived by individuals to be stressful, as well as factors that help individuals to respond to those stressors. Conventional stress models are, however, problematic because the primary emphasis is on individual perception, with little consideration of the social and cultural context in which stress occurs. This paper describes a complementary model of social and cultural influences on disease risk, placing greater emphasis on how individuals are able to approximate, in their own behaviors, shared cultural models of life, referred to as "cultural consonance". Findings from research in Brazil indicate that the higher an individual's cultural consonance, the lower his or her blood pressure. These results indicate the importance of linking different levels of analysis - the cultural, the individual, and the biological - to understand disease risk.

    To compare postoperative social costs of two cataract surgical techniques, phacoemulsification (PHACO) and extracapsular extraction (ECCE). Prospective randomized intervention study including 205 patients, of which 101 underwent PHACO and 104 ECCE in the public service, in the city of São Paulo, Southeastern Brazil, in 2002. The socioeconomic impact of these surgical procedures was assessed based on postoperative costs for patients, employers and social security. Comparisons between the two groups studied were performed using the chi-square test or Mann-Whitney test, when appropriate. A 5% significance level was set. Hospital and eyeglasses costs for PHACO were lower than for ECCE patients, with a mean difference of US$ 16.74. Costs to employers related to medical leave for the first 15 days of absence and costs of caregivers in the form of absence from work to attend postoperative follow-up visits were on average US$ 0.18 lower in PHACO compared to ECCE group. The estimated Social Security expenditure per patient undergoing surgery was US$ 6.57 and US$ 51.15 in PHACO and ECCE groups, respectively. The average saving with PHACO compared to ECCE technique was US$ 61.50 for employers, patients, caregivers and Social Security.

    Full Text Available A prospective ecological evaluation of mortality from common malignancies with dietary risk factors and alcohol consumption was carried out among 10 state capitals of Brazil. Regression analysis was used to examine the association of dietary intake with mortality rates of the most common cancers among adults age 30 years and older. Age-adjusted cancer mortality rates varied 2.4 to 3.3 fold across the state capitals. A positive relationship was observed between energy intake and colon, lung, and esophageal cancer (p<=0.02 for each. Colon cancer mortality was positively associated with consumption of total fat, eggs, alcohol, mate tea, cereals, and vegetables (p<=0.01. Lung cancer was positively associated with mate and cereal intake (p<0.05. Stomach cancer was associated with consumption of eggs (p=0.04; and negatively associated with consumption of high fiber foods, fruits, and vitamin A and C (p<=0.05. Esophageal cancer was positively associated with fat intake, mate and cereals (p<=0.05 and negatively associated with vitamin A (p=0.02; prostate cancer was negatively associated with vitamin C (p=0.007. Breast cancer was not associated with any of the factors studied. The marked variation in cancer mortality rates in Brazil may be partially related to the high variation in dietary components or other diet associated factors.

    2016-09-01

    Full Text Available Despite the serious threats that affect shark species living along the central coast of Brazil, knowledge about the life history of these animals is still scarce. The present study describes the knowledge and perceptions of fishermen from southern Bahia, Brazil, on the trophic interactions of sharks. The objective of this work was to generate information that contributes to a better understanding of the life history of sharks from this poorly known region. In 2012, semi-structured interviews were conducted with 65 fishermen, with over 15 years of experience, about fisheries and aspects of shark feeding behavior. The study found that the participants have comprehensive ethno-ecological knowledge about shark feeding habits, describing 39 types of items as components of the diets of these animals. They are also able to recognize the favored items in the diet of each ethnospecies of shark. Similar studies about shark feeding habits along the Brazilian coast should be developed. This will generate more detailed knowledge and/or new scientific hypotheses about the interspecific relationships of these predators and their prey.

    Full Text Available The semiarid Mahafaly region in southwestern Madagascar is not only a unique biodiversity hotspot, but also one of the poorest regions in the world. Crop failures occur frequently, and despite a great number of rural development programs, no effective progress in terms of improved yields, agricultural income, or well-being among farming households has been observed. In addition to the severe development challenges in the region, environmental degradation and the loss of biodiversity are prevailing issues. This paper takes a social-ecological systems perspective to analyze why the region appears locked in poverty. Specifically, we address the social-ecological interaction between environmental factors such as low and variable precipitation, the lack of sustainable intensification in agriculture resulting in recalcitrant hunger, and several environmental degradation trends. The study is based on (i longitudinal data from 150 farming households interviewed at high temporal resolution during the course of 2014, and (ii extensive recall surveys from the southwestern Madagascar project region. The analysis reveals a complex interplay of pronounced seasonality in income generation due to recurrent droughts and crop failures making local farmers highly risk averse. This interplay results in a gradual depletion of environmental assets and hinders the accumulation of capital in the hands of smallholder farmers, and improvements in agricultural production even where environmental conditions would allow for it. As a result, households are insufficiently buffered and insured against repetitive income and food security shocks. This can be understood as a set of interacting, partly nested social-ecological traps, which entrench the Mahafalian smallholder population in deep poverty while the productivity of the environment declines. We provide new insights on the interplay between hunger, poverty, and loss of environmental assets in a global biodiversity

    The correlation of the sociology of health, social ecology and media democracy is demonstrated in the study. In societies of today, the role of the media is unquestionable in disseminating information relating to health and the environment. According to Paragraph (1) of Article XXI of the Hungarian Constitution of 2011, everyone has the right to a healthy environment. An environmentalist media democracy may forward environmental justice, environmental education, and environmentalist economy, etc. All these are required in order to establish a society where the healthy environment is an objective value.

    Full Text Available Although Brazil was declared free from Chagas disease transmission by the domestic vector Triatoma infestans, human acute cases are still being registered based on transmission by native triatomine species. For a better understanding of transmission risk, the geographic distribution of Brazilian triatomines was analyzed. Sixteen out of 62 Brazilian species that both occur in >20 municipalities and present synanthropic tendencies were modeled based on their ecological niches. Panstrongylus geniculatus and P. megistus showed broad ecological ranges, but most of the species sort out by the biome in which they are distributed: Rhodnius pictipes and R. robustus in the Amazon; R. neglectus, Triatoma sordida, and T. costalimai in the Cerrado; R. nasutus, P. lutzi, T. brasiliensis, T. pseudomaculata, T. melanocephala, and T. petrocchiae in the Caatinga; T. rubrovaria in the southern pampas; T. tibiamaculata and T. vitticeps in the Atlantic Forest. Although most occurrences were recorded in open areas (Cerrado and Caatinga, our results show that all environmental conditions in the country are favorable to one or more of the species analyzed, such that almost nowhere is Chagas transmission risk negligible.

    2016-01-01

    The study of local ecological knowledge (LEK) fosters a better understanding of the relationship between humans and the environment. We assessed respondents' ecological knowledge of primates in a rural community located near the Atlantic Forest remnants in the state of Paraíba, Brazil. Populations of Alouatta belzebul (red-handed howler monkeys), Sapajus flavius (blonde capuchins), and Callithrix jacchus (the common marmoset) inhabit the region. We conducted 200 semi-structured interviews and applied thematic content analysis, with weighting, to the responses to quantify the LEK. Respondents showed a low LEK, despite the community's proximity to forest remnants. However, the LEK was significantly higher among men, as well as among those who had a greater degree of contact with the primates. Age did not influence LEK. The studied community apparently does not intensively exploit the forest resources nor does it economically depend on primates, which may explain these individuals' low levels of knowledge about these animals. Such data may support future studies, as well as environmental education and action plans, especially for A. belzebul and S. flavius, both of which are endangered species and targets of the National Action Plan for the Conservation of the Primates of the Northeast. © 2016 S.

  5. Feeding ecology of the beach silverside Atherinella blackburni (Atherinopsidae in a tropical sandy beach, Southeastern Brazil

    Júlio Guazzelli Gonzalez

    Full Text Available Abstract The feeding ecology of the beach silverside (Atherinella blackburni in the surf zone of a tropical sand beach, located in the southeastern Brazil, was accessed through the gut content analysis of 198 fish. Factors such as fish's size, season and day period were analysed to understand how these variables affect the diet composition of the species. Results show that A. blackburni is a coastal neritic fish with a broad feeding niche. Most recurrent prey were zooplanktonic crustaceans, insects and benthic molluscs, in which Copepoda crustaceans were the dominant dietary item in occurrence and abundance. A. blackburni appears to have a slight ontogenetic shift in its diet, changing from benthic molluscs to crustaceans and insects along its life cycle. The diel activity also reveals to be an important factor to the A. blackburni feeding ecology. The predominant occurrence of small fish during the morning, along with the main preys for this size class, suggests that small individuals use shallower waters as feeding grounds during the morning and, during the night, they move to deeper waters for protection against predators.

  6. The Oak Ridges Moraine as a Social Innovation: Strategic Vision as a Social-Ecological Interaction

    Full Text Available The Oak Ridges Moraine (ORM case is unique in that it represents a social innovation in Canadian, if not North American, ecosystem-based land-use planning. A social innovation is an initiative, product, process, or program that profoundly changes the basic routines, resources, and authority flows or beliefs of any social system. Successful social innovations have durability and broad impact. We interpret the narrative of the ORM conservation process to explore the utility of an emerging social innovation conceptual model, the 'vision as social interaction' framework using resilience thinking and the role of vision in social change within complex social-ecological systems. Qualitative data from two interrelated studies of the moraine were reinterpreted and include 38 in-depth, semistructured interviews conducted between 2004-2006, as well as extensive participant observation at over 50 moraine conservation meetings, workshops, and events. The results of our study indicate that emerging model of social innovation can be linked with other models of 'radical change' such as those that employ concepts like 'policy windows' to describe opportunities for continued innovation once an initiative has reached the routinized phase. Just as with the panarchy cycle, when a social-ecological system reaches the conservation phase, the system has a propensity to collapse and reorganize. Rather than seeing this as the end of an initiative or program, such as is the case with the ORM, stakeholders can see it as an opportunity for reorganization with newly released resources and new opportunities.

    To analyze the social participation taking place through Municipal Health Councils (MHC) in two small towns in northeastern Brazil. A qualitative, exploratory, multicase study focused on the MHCs of Lafayete Coutinho (state of Bahia) and Groaíras (state of Ceará) was conducted. Data were gathered from February-April 2005 through analysis of documents, direct observation of MHC meetings, and semistructured interviews. Documents analyzed included decrees, laws, and municipal regulations; city health department annual management reports; municipal health plans; and reports of municipal health conferences. MHC meeting minutes for the period between inception of these councils and 2004 were also reviewed. Interviews of 17 council members took place, eight of whom were from Lafayete Coutinho and nine from Groaíras. Both councils had irregular practices regarding membership structure and nomination of members, such as frequent changes in appointed members and continuous "reshuffling" of council structure. In addition, new council members were appointed each time a new mayor took charge. Sporadic frequency of meetings was also observed. In Lafayete Coutinho, of 96 meetings planned, just 37 took place; in Groaíras, of 186 meetings planned, 93 took place. Analysis of MHC efforts to formulate and control municipal health policies revealed three themes: health status of the population and public policies; organization and functioning of health services; and financial management and accounting. The interviews showed that council members were dissatisfied with the practices of the MHCs and revealed a lack of confidence in how truly representative the councils are and how much power they have. Social participation strategies in Brazil must be reconsidered with an angle toward promoting political responsibility and raising awareness among citizens.

  8. Agrarian Social Movements and the Making of Agrodiesel Moral Territories in Northeast Brazil

    Manzi, Maya

    In response to widespread concerns about the socio-ecological impacts of agrofuel production and development, particularly for food security, efforts have been made internationally to implement more sustainable forms of producing agrofuels. Brazil's National Program for the Production and Use of Agrodiesel (PNPB), launched in 2004, is one such attempt. Promoted as a socially and environmentally responsible program, the PNPB was made possible through unprecedented alliances between the 'postneoliberal' Brazilian state, the agribusiness sector, and social movements such as the Rural Trade Union's Movement (MSTTR) and the Landless Rural Workers' Movement (MST). In this research, I critically analyze the unexpected engagement of social movements in the making of agrodiesel territories in semi-arid Bahia, Northeastern Brazil by examining the territorial and moral processes and practices that underlie the production of castor bean (mamona) for agrodiesel. The methodology adopted comprised participant observation, informal and semi-structured interviews (n=74) with leaders and members of the MST and the MSTTR in the territories of the Chapada Diamantina and Irece, in central Bahia. Interviews were also conducted with representatives of family farming cooperatives, government institutions, and agrodiesel companies (Petrobras) in the two study areas and in Salvador, capital of Bahia. Research methods also included the collection and critical discourse analysis of archival and other secondary data sources from public and private institutions. Drawing mainly from cultural geography and political ecology literatures, I argue that social movement leaders enable the making of agrodiesel territories mainly through their role as 'agrodiesel gatekeepers'---as legal interveners, managers, and caregivers. Family farmers tend to enable agrodiesel territorial expansion and to disrupt agrodiesel territorial management by not complying with moral prescriptions of loyalty. I see farmers

    Full Text Available Scientists are increasingly called upon to integrate across ecological and social disciplines to tackle complex coupled human and natural system (CHANS problems. Integration of these disciplines is challenging and many scientists do not have experience with large integrated research projects. However, much can be learned about the complicated process of integration from such efforts. We document some of these lessons from a National Science Foundation-funded CHANS project (Forests, People, Fire and present considerations for developing and engaging in coupled human and natural system projects. Certainly we are not the first to undertake this endeavor, and many of our findings complement those of other research teams. We focus here on the process of coming together, learning to work as an integrated science team, and describe the challenges and opportunities of engaging stakeholders (agency personnel and citizen communities of interests in our efforts. Throughout this project our intention was to foster dialogue among diverse interests and, thus, incorporate this knowledge into uncovering primary social and ecological drivers of change. A primary tool was an agent-based model, Envision, that used this information in landscape simulation, visualization models, and scenario development. Although integration can be an end in itself, the proof of value in the approach can be the degree to which it provides new insights or tools to CHANS, including closer interaction among multiple stakeholders, that could not have been reached without it.

  11. Resilience, Adaptability and Transformability in Social-ecological Systems

    2004-12-01

    Full Text Available The concept of resilience has evolved considerably since Holling's (1973 seminal paper. Different interpretations of what is meant by resilience, however, cause confusion. Resilience of a system needs to be considered in terms of the attributes that govern the system's dynamics. Three related attributes of social-ecological systems (SESs determine their future trajectories: resilience, adaptability, and transformability. Resilience (the capacity of a system to absorb disturbance and reorganize while undergoing change so as to still retain essentially the same function, structure, identity, and feedbacks has four components - latitude, resistance, precariousness, and panarchy - most readily portrayed using the metaphor of a stability landscape. Adaptability is the capacity of actors in the system to influence resilience (in a SES, essentially to manage it. There are four general ways in which this can be done, corresponding to the four aspects of resilience. Transformability is the capacity to create a fundamentally new system when ecological, economic, or social structures make the existing system untenable. The implications of this interpretation of SES dynamics for sustainability science include changing the focus from seeking optimal states and the determinants of maximum sustainable yield (the MSY paradigm, to resilience analysis, adaptive resource management, and adaptive governance.

  12. Resilience in Pre-contact Pacific Northwest Social Ecological Systems

    2003-12-01

    Full Text Available If, like other ecosystems, the variable and dynamic ecosystems of the Pacific Northwest exhibited cycles and unpredictable behavior, particularly when humans were present, the indigenous societies of that region had to have been resilient in order to persist for such a long time. They persisted for two millennia prior to contact with people from the "old world." The Resilience Alliance (2002 proposes that social and ecological resilience requires three abilities: the ability to buffer, the ability to self-organize, and the ability to learn. This paper suggests that the characteristics of the potlatch system among Indians on the Northwest Coast, namely property rights, environmental ethics, rules of earning and holding titles, public accountability, and the reciprocal exchange system, provided all three required abilities. The resulting resilience of these societies confirms the validity of many of the ideas now being discussed as important components in providing successful and sustainable relationships between humans and their ecosystems. That so many separate ideas seem to have been linked together into resilient systems in the Pacific Northwest suggests that social ecological resilience is complicated.

  13. Robustness Trade-offs in Social-Ecological Systems

    Directory of Open Access Journals (Sweden)

    Marco A. Janssen

    2007-10-01

    Full Text Available The governance of common-pool resources can be meaningfully examined from the somewhat broader perspective of the governance of social-ecological systems (SESs. Governance of SESs invariably involves trade-offs; trade-offs between different stakeholder objectives, trade-offs between risk and productivity, and trade-offs between short-term and long-term goals. This is especially true in the case of robustness in social-ecological systems - i.e. the capacity to continue to meet a performance objective in the face of uncertainty and shocks. In this paper we suggest that effective governance under uncertainty must include the ongoing analysis of trade-offs between robustness and performance, and between investments in robustness to different types of perturbations. The nature of such trade-offs will depend on society's perception of risk, the dynamics of the underlying resource, and the governance regime. Specifically, we argue that it is impossible to define robustness in absolute terms. The choice for society is not only whether to invest in becoming robust to a particular disturbance, but rather, what suit of disturbances to address and what set of associated vulnerabilities is it willing to accept as a necessary consequence.

    Premature loss of offspring decreases direct fitness of parents. In gregarious mammals, both ecological and social variables impact offspring survival and may interact with each other in this regard. Although a number of studies have investigated factors influencing offspring loss in mammals, we still know very little on how different factors interact with one another. We therefore investigated fetal and infant mortality in 3 large groups of wild crested macaques (Macaca nigra) over a period of up to 5 years by including potential social causes such as maternal dominance rank, male immigration, between group encounters, and ecological conditions such as rainfall in a multivariate survival analysis using Cox proportional hazards model. Infant but not fetal survival was most impaired after a recent takeover of the alpha-male position by an immigrant male. Furthermore, infant survival probability increased when there was an increase in number of group adult females and rainfall. Fetal survival probability also increased with an increase of these 2 factors, but more in high-ranking than low-ranking females. Fetal survival, unlike that of infants, was also improved by an increase of intergroup encounter rates. Our study thus stresses the importance of survival analyses using a multivariate approach and encompassing more than a single offspring stage to investigate the determinants of female direct fitness. We further provide evidence for fitness costs and benefits of group living, possibly deriving from high pressures of both within- and between-group competition, in a wild primate population.

  15. Social ecology of resilience and Sumud of Palestinians.

    2018-01-01

    The aim of this article is to provide an overview of theoretical perspectives and practical research knowledge in relation to 'resilience', the resilience of Palestinians in particular and the related concept of 'Sumud'. 'Sumud' is a Palestinian idea that is interwoven with ideas of personal and collective resilience and steadfastness. It is also a socio-political concept and refers to ways of surviving in the context of occupation, chronic adversity, lack of resources and limited infrastructure. The concept of 'resilience' has deep roots, going back at least to the 10th century when Arabic scholars suggested strategies to cope with life adversity. In Europe, research into resilience extends back to the 1800s. The understanding of resilience has developed over four overlapping waves. These focus on individual traits, protective factors, ecological assets and (in the current wave) social ecological factors. The current wave of resilience research focuses on the contribution of cultural contextualisation and is an approach that is discussed in this article, which draws on Arabic and English language literature located through a search of multiple databases (CINAHL, British Nursing Index, ASSIA, MEDLINE, PsycINFO and EMBASE). Findings suggest that 'Sumud' is linked to the surrounding cultural context and can be thought of as an innovative, social ecological, approach to promoting resilience. We show that resilience is a prerequisite to 'Sumud', meaning that the individual has to be resilient in order to stay and not to leave their place, position or community. We close by pressing the case for studies which investigate resilience especially in underdeveloped countries such as Palestine (occupied Palestinian territories), and which reveal how resilience is embedded in pre-existing cultural contexts.

Developing a fuller understanding of the concept of social-ecological resilience promises advances in how science can contribute to achieving better environmental outcomes, locally and globally. Such a development requires articulation of different perspectives on resilience and critical engagement across those perspectives. We present, in some detail, a particular perspective on resilience developed by the pioneering social psychologist Kurt Lewin. We suggest that Lewin's explicit use of social-ecological systems in his framework presaged much of the current social-ecological understanding of resilience. We set out some key details of his framework, notably the characteristics of his field theory, his use of group dynamics as a vehicle for social change, his introduction and development of the principles of action research, and his three-step change model. We conclude by mentioning some areas of the framework that are under-theorized or not theorized at all.

  18. Social network models predict movement and connectivity in ecological landscapes

    Network analysis is on the rise across scientific disciplines because of its ability to reveal complex, and often emergent, patterns and dynamics. Nonetheless, a growing concern in network analysis is the use of limited data for constructing networks. This concern is strikingly relevant to ecology and conservation biology, where network analysis is used to infer connectivity across landscapes. In this context, movement among patches is the crucial parameter for interpreting connectivity but because of the difficulty of collecting reliable movement data, most network analysis proceeds with only indirect information on movement across landscapes rather than using observed movement to construct networks. Statistical models developed for social networks provide promising alternatives for landscape network construction because they can leverage limited movement information to predict linkages. Using two mark-recapture datasets on individual movement and connectivity across landscapes, we test whether commonly used network constructions for interpreting connectivity can predict actual linkages and network structure, and we contrast these approaches to social network models. We find that currently applied network constructions for assessing connectivity consistently, and substantially, overpredict actual connectivity, resulting in considerable overestimation of metapopulation lifetime. Furthermore, social network models provide accurate predictions of network structure, and can do so with remarkably limited data on movement. Social network models offer a flexible and powerful way for not only understanding the factors influencing connectivity but also for providing more reliable estimates of connectivity and metapopulation persistence in the face of limited data.

  20. Resilience, political ecology, and well-being: an interdisciplinary approach to understanding social-ecological change in coastal Bangladesh

    Directory of Open Access Journals (Sweden)

    Sonia F. Hoque

    2017-06-01

    Full Text Available The commodification of peasant livelihoods through export-oriented aquaculture has brought about significant social-ecological changes in low-lying coastal areas in many parts of Asia. A better understanding of the underlying drivers and distributional effects of these changes requires integration of social and ecological approaches that often have different epistemological origins. Resilience thinking has gained increased traction in social-ecological systems research because it provides a dynamic analysis of the cross-scalar interactions between multiple conditions and processes. However, the system-oriented perspective inherent in resilience thinking fails to acknowledge the heterogeneous values, interests, and power of social actors and their roles in navigating social-ecological change. Incorporation of political ecology and well-being perspectives can provide an actor-oriented analysis of the trade-offs associated with change and help to determine which state is desirable for whom. However, empirical demonstrations of such interdisciplinary approaches remain scarce. Here, we explore the combined application of resilience, political ecology, and well-being in investigating the root causes of social-ecological change and identifying the winners and losers of system transformation through empirical analysis of the differential changes in farming systems in two villages in coastal Bangladesh. Using the adaptive cycle as a structuring model, we examine the evolution of the shrimp aquaculture system over the past few decades, particularly looking at the power dynamics between households of different wealth classes. We found that although asymmetric land ownership and political ties enabled the wealthier households to reach their desired farming system in one village, social resilience achieved through memory, leadership, and crisis empowered poorer households to exercise their agency in another village. Material dimensions such as improved

  1. Double coupling: modeling subjectivity and asymmetric organization in social-ecological systems

    Full Text Available Social-ecological organization is a multidimensional phenomenon that combines material and symbolic processes. However, the coupling between social and ecological subsystem is often conceptualized as purely material, thus reducing the symbolic dimension to its behavioral and actionable expressions. In this paper I conceptualize social-ecological systems as doubly coupled. On the one hand, material expressions of socio-cultural processes affect and are affected by ecological dynamics. On the other hand, coupled social-ecological material dynamics are concurrently coupled with subjective dynamics via coding, decoding, personal experience, and human agency. This second coupling operates across two organizationally heterogeneous dimensions: material and symbolic. Although resilience thinking builds on the recognition of organizational asymmetry between living and nonliving systems, it has overlooked the equivalent asymmetry between ecological and socio-cultural subsystems. Three guiding concepts are proposed to formalize double coupling. The first one, social-ecological asymmetry, expands on past seminal work on ecological self-organization to incorporate reflexivity and subjectivity in social-ecological modeling. Organizational asymmetry is based in the distinction between social rules, which are symbolically produced and changed through human agents' reflexivity and purpose, and biophysical rules, which are determined by functional relations between ecological components. The second guiding concept, conscious power, brings to the fore human agents' distinctive capacity to produce our own subjective identity and the consequences of this capacity for social-ecological organization. The third concept, congruence between subjective and objective dynamics, redefines sustainability as contingent on congruent relations between material and symbolic processes. Social-ecological theories and analyses based on these three guiding concepts would support the

    2014-01-01

    Core themes of geomorphology include: open systems and connectivity; feedbacks and complexity; spatial differentiation of dominant physical processes within a landscape; and legacy effects of historical human use of resources. Core themes of ecology include: open systems and connectivity; hierarchical, heterogeneous, dynamic, and context-dependent characteristics of ecological patterns and processes; nonlinearity, thresholds, hysteresis, and resilience within ecosystems; and human effects. Core themes of environmental governance include: architecture of institutions and decision-making; agency, or ability of actors to prescribe behavior of people in relation to the environment; adaptiveness of social groups to environmental change; accountability and legitimacy of systems of governance; allocation of and access to resources; and thresholds and feedback loops within environmental policy. Core themes common to these disciplines include connectivity, feedbacks, tipping points or thresholds, and resiliency. Emphasizing these points of disciplinary overlap can facilitate interdisciplinary understanding of complex systems, as well as more effective management of landscapes and ecosystems by highlighting drivers of change within systems. We use a previously published conceptual framework to examine how these core themes can be integrated into interdisciplinary research for human-landscape systems via the example of a river.

  3. Ecosystem Services as a Boundary Concept: Arguments from Social Ecology

    Directory of Open Access Journals (Sweden)

    Christian Schleyer

    2017-06-01

    Full Text Available Ecosystem services (ES are defined as the interdependencies between society and nature. Despite several years of conceptual discussions, some challenges of the ES concept are far from being resolved. In particular, the usefulness of the concept for nature protection is questioned, and a strong critique is expressed concerning its contribution towards the neoliberal commodification of nature. This paper argues that these challenges can be addressed by dealing more carefully with ES as a boundary concept between different disciplines and between science and society. ES are neither about nature nor about human wellbeing, but about the mutual dependencies between nature and human wellbeing. These mutual interdependencies, however, create tensions and contradictions that manifest themselves in the boundary negotiations between different scientific disciplines and between science and society. This paper shows that approaches from Social Ecology can address these boundary negotiations and the power relations involved more explicitly. Finally, this implies the urgent need for more inter- and transdisciplinary collaboration in ES research. We conclude (1 that the social–ecological nature of ES must be elaborated more carefully while explicitly focussing on the interdependencies between nature and society; (2 to better implement inter- and transdisciplinary methods into ES research; and (3 that such ES research can—and to some extent already does—substantially enhance international research programmes such as Future Earth.

    Full Text Available This article introduces the Social-ecological systems meta-analysis database (SESMAD project, which is the project behind the case studies and synthetic articles contained in this special issue of the International Journal of the Commons. SESMAD is an internationally collaborative meta-analysis project that builds on previous seminally synthetic work on small-scale common-pool resource systems conducted at the Workshop in Political Theory and Policy Analysis at Indiana University. This project is guided by the following research question: can the variables found to be important in explaining outcomes on small-scale systems be scaled up to explain outcomes in large-scale environmental governance? In this special issue we report on our findings thus far through a set of case studies of large-scale environmental governance, a paper that describes our conceptual advances, and a paper that compares these five case studies to further examine our central research question.

    Abrahamson, M; Johnson, P

    1974-08-01

    This paper examines the characteristics of residential zones in Madrid, Spain. The primary difference between zones is found to lie in a new bourgeoisie life-style dimension. Working women are found to be the best indicator of this dimension, which also involves servants, natives of Madrid and high degrees of literacy. Fertility-related considerations, however, are unrelated to working women, and this is explained as due to the availability of domestic help and "women-oriented" working arrangements. Fertility and socioeconomic status are found to be interrelated and constitute a second dimension of residential segregation. In conclusion, Madrid is examined in relation to both more and less industrialized cities, leading to a further modification of social area theory contentions concerning the ecology of stratification in developing cities.

    Full Text Available Abstract Background Previous research points to differences between predictors of intention to screen for colorectal cancer (CRC and screening behavior, and suggests social ecological factors may influence screening behavior. The aim of this study was to compare the social cognitive and social ecological predictors of intention to screen with predictors of participation. Methods People aged 50 to 74 years recruited from the electoral roll completed a baseline survey (n = 376 and were subsequently invited to complete an immunochemical faecal occult blood test (iFOBT. Results Multivariate analyses revealed five predictors of intention to screen and two predictors of participation. Perceived barriers to CRC screening and perceived benefits of CRC screening were the only predictor of both outcomes. There was little support for social ecological factors, but measurement problems may have impacted this finding. Conclusions This study has confirmed that the predictors of intention to screen for CRC and screening behaviour, although overlapping, are not the same. Research should focus predominantly on those factors shown to predict participation. Perceptions about the barriers to screening and benefits of screening are key predictors of participation, and provide a focus for intervention programs.

  7. Risk Mapping for Avian Influenza: a Social-Ecological Problem

    2010-09-01

    Full Text Available Pathogen dynamics are inseparable from the broader environmental context in which pathogens occur. Although some pathogens of people are primarily limited to the human population, occurrences of zoonoses and vector-borne diseases are intimately linked to ecosystems. The emergence of these diseases is currently being driven by a variety of influences that include, among other things, changes in the human population, long-distance travel, high-intensity animal-production systems, and anthropogenic modification of ecosystems. Anthropogenic impacts on ecosystems have both direct and indirect (food-web mediated effects. Therefore, understanding disease risk for zoonoses is a social-ecological problem. The articles in this special feature focus on risk assessment for avian influenza. They include analyses of the history and epidemiological context of avian influenza; planning and policy issues relating to risk; the roles of biogeography and spatial and temporal variation in driving the movements of potential avian influenza carriers; approaches to quantifying risk; and an assessment of risk-related interactions among people and birds in Vietnamese markets. They differ from the majority of published studies of avian influenza in that they emphasize unknowns and uncertainties in risk mapping and societal responses to avian influenza, rather than concentrating on known or proven facts. From a systems perspective, the different aspects of social-ecological systems that are relevant to the problem of risk mapping can be summarized under the general categories of structural, spatial, and temporal components. I present some examples of relevant system properties, as suggested by this framework, and argue that, ultimately, risk mapping for infectious disease will need to develop a more holistic perspective that includes explicit consideration of the roles of policy, disease management, and feedbacks between ecosystems and societies.

    Full Text Available The laboratory and field observations summarized in this paper on visceral leishmaniasis ecology in the State of Bahia, Brazil are based on the author's observations over the past 35 years in a number of state's foci, public health records and literature citations. The disease is endemic with epidemic outbreaks occurring every ten years and its geographical distribution is expanding rapidly in the last years. Leishmania chagasi is the main ethiologic agent of the visceral leishmaniasis but Le. amazonensis s. lato was the only leishmania isolated by other authors from some visceral leishmaniasis human cases in the state. Lutzomyia longipalpis (with one or two spots on tergites III and IV and two sized different populations was epidemiologically incriminated as the main vector. It was found naturally infected with promastigotes, and it was infected with four species of leishmanias in the laboratory. Although the experimental transmission of Le. amazonensis by the bite of Lu. longipalpis to hamsters was performed, the author was not successful in transmitting Le. chagasi in the same way. The dog is the most important domestic source for infection of the vector, however it is not a primary reservoir. The opossum Didelphis albiventris was found naturally infected with Le. chagasi but its role as reservoir is unknown. Foxes and rodents were not found infected with leishmanias in Bahia.

    In the present study we aimed to compare the feeding ecology of Hypostomus punctatus from a coastal stream from Southeast Brazil with data previously published for the same study site before environmental changes. Feeding preferences were assessed through a sample of 138 specimens (67 from the dry and 71 from the rainy season) using the Index of Alimentary Importance (IAi). We registered five different food items (detritus, plant fragments, Diatoms, Chloroficeae and Cianobacteries) composing the species diet. Detritus was the most abundant one both during the rainy and dry seasons (IAirainny = 90.34 and IAidry = 96.30). No significant differences were registered for the volume of food items consumed during the rainy and dry seasons. The Frequency of Occurrence analysis showed that four (detritus, plant fragments, Diatoms and Chloroficeae) among the five all other consumed ones, were always frequent. Comparing our own results with those available for the study site, we suggest that the feeding habit of H. punctatus has changed according to environmental changes and that the species diet is strongly dependent upon environmental conditions.

    Many theories highlight the role social contexts play in shaping affective experience. However, little is known about how individuals' social environments influence core affect on short time-scales (e.g., hours). Using experience sampling data from the iSAHIB, wherein 150 adults aged 18 to 89 years reported on 64,213 social interactions (average 6.92 per day, SD = 2.85) across 9 weeks of daily life, we examined how 4 features of individuals' social ecology (between-person differences) and immediate social situations (within-person changes) were associated with core affect-valence and arousal-and how those associations differ with age. Results from multilevel models revealed that familiarity, importance, type of social partner, and gender composition of the social context were associated with affect valence and/or affect arousal. Higher familiarity, higher importance, and same-gender composition were associated with more positive affect valence and higher arousal. Interactions with family and friends were linked to more positive valence whereas nonfamily social partners were linked to higher arousal. Age moderated the associations between importance and affect arousal, and between type of social partner and both dimensions of core affect. Findings align with theoretical propositions, contributing to but also suggesting need for further precision regarding how development shapes the interplay between social context and moment-to-moment affective experience.

    Full Text Available Innovative combinations of social and ecological theory are required to deal with complexity and change in human-ecological systems. We examined the interplay and complementarities that emerge by linking resilience and social well-being approaches. First, we reflected on the limitations of applying ecological resilience concepts to social systems from the perspective of social theory, and particularly, the concept of well-being. Second, we examined the interplay of resilience and well-being concepts in fostering a social-ecological perspective that promises more appropriate management and policy actions. We examined five key points of interplay: (1 the limits of optimization thinking (e.g., maximum sustainable yield, (2 the role of human agency and values, (3 understandings of scale, (4 insights on "controlling variables," and (5 perspectives on thresholds and boundaries. Based on this synthesis, we offer insights to move incrementally towards interdisciplinary research and governance for complex social-ecological systems.

    Full Text Available This research was based on a study of social enterprises in Brazil, to find out if and how these organizations plan and manage the succession process for their senior positions. The study investigated the subset of the associations dedicated to collectively producing goods and services, because they are formally set up and aimed at speeding up the dynamism of local development. The empirical research consisted of two stages. The first was a survey covering a sample of 378 organizations, to find out which of those had already undergone or were undergoing a succession process. The second interviewed the main manager of 32 organizations, to obtain a description of their succession experience. In this stage, the research aimed to analyze how the Individual, Organization and Environment dimensions interact to configure the succession process, identifying which factors of each of these dimensions can facilitate or limit this process. The following guiding elements were taken as the analytical basis: Individual dimension - leadership roles, skill and styles; Organization dimension - structure, planning, advisory boards, communication (transparency, control and evaluation; and Environment dimension - influence of the stakeholders (community, suppliers, clients, and business partners on the succession process. The results indicated that succession in the researched associations is in the construction stage: it adapts to the requirements of current circumstances but is evidently in need of improvement in order for more effective planning and shared management of the process to be achieved.

    The (re)construction of the ecological continuity is stated as one of the main objectives of the European Water Framework Directive for watershed management in Europe. Analysing the social, political, technical and scientific processes characterising the implementation of different projects of ecological continuity in two adjacent peri-urban territories in Ile-de-France, we observed science-driven approaches disregarding the social contexts. We show that, in urbanized areas, ecological continuity requires not only important technical and ecological expertise, but also social and political participation to the definition of a common vision and action plan. Being a challenge for both, technical water management institutions and "classical" ecological policies, we propose some social science contributions to deal with ecological unpredictability and reconsider stakeholder resistance to this kind of project.

    Full Text Available Previous research suggests that reputational concerns can incentivize cooperation and deter socially deviant behavior. The current research showed that social monitoring of information that has the potential to damage one's reputation has differential effects on deviant behavior in social-ecological environments that vary in level of mobility. Study 1 showed that residentially stable cities that employed more journalists-who can be regarded as social monitoring agents in a community-tended to have lower rates of violent crime than residentially stable cities that employed fewer journalists; by contrast, in residentially mobile cities, violent crime rates did not vary as a function of the number of journalists employed. In Study 2, we found that individual differences in perceptions of relational mobility moderated the effects of social monitoring on cheating in a die-under-cup game. Specifically, social monitoring cues reduced the likelihood of cheating but only among participants who perceived their immediate social environment to be low in relational mobility. The same results were replicated in Study 3, an experiment in which participants' perception of relational mobility was manipulated before completing an online maze game that allowed them to earn extra cash. In the low mobility condition, the percentage of participants who continued working on the mazes after reaching the time limit decreased as a function of social monitoring; however, this pattern was not observed in the high mobility condition. Together, our findings suggest that socioecological context matters for understanding effective mechanisms of social control.

    2002-08-01

    In this paper we address the pervasive tendency in community psychology to treat values like social justice only as general objectives rather than contested theoretical concepts possessing identifiable empirical content. First we discuss how distinctive concepts of social justice have figured in three major intellectual traditions within community psychology: (1) the prevention and health promotion tradition, (2) the empowerment tradition, and most recently, (3) the critical tradition. We point out the epistemological gains and limitations of these respective concepts and argue for greater sensitivity to the context dependency of normative concepts like social justice. More specifically, we point to a pressing need in community psychology for an epistemology that: (1) subsumes both descriptive and evaluative concepts, and (2) acknowledges its own embeddedness in history and culture without thereby reducing all knowledge claims to the status of ideology. Finally, we describe and demonstrate the promise of what we are calling a social ecological epistemology for fulfilling this need.

    Unequal distribution of emergency care services is a critical barrier to be overcome to assure access to emergency and surgical care. Considering this context it was objective of the present work analyze geographic access barriers to emergency care services in Brazil. A secondary aim of the study is to define possible roles to be assumed by small hospitals in the Brazilian healthcare network to overcome geographic access challenges. The present work can be classified as a cross-sectional ecological study. To carry out the present study, data of all 5843 Brazilian hospitals were categorized among high complexity centers and small hospitals. The geographical access barriers were identified through the use of two-step floating catchment area method. Once concluded the previous step an evaluation using the Getis-Ord-Gi method was performed to identify spatial clusters of municipalities with limited access to high complexity centers but well covered by well-equipped small hospitals. The analysis of accessibility index of high complexity centers highlighted large portions of the country with nearly zero hospital beds by inhabitant. In contrast, it was possible observe a group of 1595 municipalities with high accessibility to small hospitals, simultaneously with a low coverage of high complexity centers. Among the 1595 municipalities with good accessibility to small hospitals, 74% (1183) were covered by small hospitals with at least 60% of minimum emergency service requirements. The spatial clusters analysis aggregated 589 municipalities with high values related to minimum emergency service requirements. Small hospitals in these 589 cities could promote the equity in access to emergency services benefiting more than eight million people. There is a spatial disequilibrium within the country with prominent gaps in the health care network for emergency services. Taking this challenge into consideration, small hospitals could be a possible solution and foster equity in access

  4. Evaluating social and ecological vulnerability of coral reef fisheries to climate change.

    Full Text Available There is an increasing need to evaluate the links between the social and ecological dimensions of human vulnerability to climate change. We use an empirical case study of 12 coastal communities and associated coral reefs in Kenya to assess and compare five key ecological and social components of the vulnerability of coastal social-ecological systems to temperature induced coral mortality [specifically: 1 environmental exposure; 2 ecological sensitivity; 3 ecological recovery potential; 4 social sensitivity; and 5 social adaptive capacity]. We examined whether ecological components of vulnerability varied between government operated no-take marine reserves, community-based reserves, and openly fished areas. Overall, fished sites were marginally more vulnerable than community-based and government marine reserves. Social sensitivity was indicated by the occupational composition of each community, including the importance of fishing relative to other occupations, as well as the susceptibility of different fishing gears to the effects of coral bleaching on target fish species. Key components of social adaptive capacity varied considerably between the communities. Together, these results show that different communities have relative strengths and weaknesses in terms of social-ecological vulnerability to climate change.

  5. Scale Mismatches in Social-Ecological Systems: Causes, Consequences, and Solutions

    2006-06-01

    Full Text Available Scale is a concept that transcends disciplinary boundaries. In ecology and geography, scale is usually defined in terms of spatial and temporal dimensions. Sociological scale also incorporates space and time, but adds ideas about representation and organization. Although spatial and temporal location determine the context for social and ecological dynamics, social-ecological interactions can create dynamic feedback loops in which humans both influence and are influenced by ecosystem processes. We hypothesize that many of the problems encountered by societies in managing natural resources arise because of a mismatch between the scale of management and the scale(s of the ecological processes being managed. We use examples from southern Africa and the southern United States to address four main questions: (1 What is a "scale mismatch?" (2 How are scale mismatches generated? (3 What are the consequences of scale mismatches? (4 How can scale mismatches be resolved? Scale mismatches occur when the scale of environmental variation and the scale of social organization in which the responsibility for management resides are aligned in such a way that one or more functions of the social-ecological system are disrupted, inefficiencies occur, and/or important components of the system are lost. They are generated by a wide range of social, ecological, and linked social-ecological processes. Mismatches between the scales of ecological processes and the institutions that are responsible for managing them can contribute to a decrease in social-ecological resilience, including the mismanagement of natural resources and a decrease in human well-being. Solutions to scale mismatches usually require institutional changes at more than one hierarchical level. Long-term solutions to scale mismatch problems will depend on social learning and the development of flexible institutions that can adjust and reorganize in response to changes in ecosystems.

    Climate variability is an inherent characteristic of the Earth's climate, including but not limited to climate change. It affects and impacts human society in different ways, depending on the underlying socioeconomic vulnerability of specific places, social groups, households and individuals. This differential vulnerability presents spatial and temporal variations, and is rooted in historical patterns of development and relations between human and ecological systems. This study aims to assess the impact of climate variability on livelihoods and well-being, as well as their changes over time and across space, and for rural and urban populations. The geographic focus is Southern Brazil-the states of Parana, Santa Catarina and Rio Grande do Sul-- and the objectives include (a) to identify and map critical areas or hotspots of exposure to climate variability (temperature and precipitation), and (b) to identify internal variation or differential vulnerability within these areas and its evolution over time (1980-2010), using newly available integrated data from the Terra Populus project. These data include geo-referenced climate and agricultural data, and data describing demographic and socioeconomic characteristics of individuals, households and places.

    An ecological study was carried out using information zones as units of analysis in order to assess the evolution of socio-spatial inequalities in mortality due to external causes and homicides in Salvador, Bahia State, Brazil, in 2000 and 2006. The Brazilian Institute of Geography and Statistics (Instituto Brasileiro de Geografia e Estatística--IBGE) and the City Health Department (Secretaria Municipal de Saúde) provided the data sources, and causes of death were reviewed and reclassified based on reports from the Institute of Legal Medicine (Instituto Médico Legal). The information zones were classified into four social strata according to income and schooling. The ratio between mortality rates (inequality ratio) was calculated and confirmed a rise of 98.5% in the homicide rate. In 2000, the risk of death due to external causes and murders in the stratum with the worst living conditions was respectively 1.40 and 1.94 times greater than in the reference stratum. In 2006 these figures were 2.02 and 2.24. The authors discuss the implications for inter-sectoral public policies, based on evidence from the study's findings.

    Over the past decades, the field of bullying research has seen dramatic growth, notably with the integration of the social-ecological approach to understanding bullying. Recently, researchers (Hymel et al., 2015; Hawley & Williford, 2015) have called for further extension of the field by incorporating constructs of group processes into our investigation of the social ecologies of bullying. This brief note details the critical connections between power, social identity, group norms, social and moral reasoning about discrimination and victimization, and experiences of, evaluations of, and responses to bullying. The authors highlight a parallel development in the bridging of developmental social-ecological and social psychological perspectives utilized in the field of social exclusion that provides a roadmap for extending the larger field of bullying research.

    The stark observation of the co-existence of undernourishment, nutrient deficiencies and overweight and obesity, the triple burden of malnutrition, is inviting us to reconsider health and nutrition as the primary goal and final endpoint of food systems. Agriculture and the food industry have made remarkable advances in the past decades. However, their development has not entirely fulfilled health and nutritional needs, and moreover, they have generated substantial collateral losses in agricultural biodiversity. Simultaneously, several regions are experiencing unprecedented weather events caused by climate change and habitat depletion, in turn putting at risk global food and nutrition security. This coincidence of food crises with increasing environmental degradation suggests an urgent need for novel analyses and new paradigms. The sustainable diets concept proposes a research and policy agenda that strives towards a sustainable use of human and natural resources for food and nutrition security, highlighting the preeminent role of consumers in defining sustainable options and the importance of biodiversity in nutrition. Food systems act as complex social-ecological systems, involving multiple interactions between human and natural components. Nutritional patterns and environment structure are interconnected in a mutual dynamic of changes. The systemic nature of these interactions calls for multidimensional approaches and integrated assessment and simulation tools to guide change. This paper proposes a review and conceptual modelling framework that articulate the synergies and tradeoffs between dietary diversity, widely recognised as key for healthy diets, and agricultural biodiversity and associated ecosystem functions, crucial resilience factors to climate and global changes.

  10. Ecological History vs. Social Expectations: Managing Aquatic Ecosystems

    Directory of Open Access Journals (Sweden)

    Gordon H. Reeves

    2009-12-01

    Full Text Available The emerging perspective of ecosystems as both non-equilibrium and dynamic fits aquatic ecosystems as well as terrestrial systems. It is increasingly recognized that watersheds historically passed through different conditions over time. Habitat conditions varied in quantity and quality, primarily as a function of the time since the last major disturbance and the legacy of that disturbance. Thus, to match the effects of historical processes, we would expect a variety of conditions to exist across the watersheds in a region at any time. Additionally, watersheds have different potentials to provide habitat for given fish species because of variation in physical features. This developing ecological understanding is often preempted by social desires to bring all watersheds to a "healthy" condition, which in turn is reflected in a common regulatory approach mandating a single condition as the long-term goal for all watersheds. Matching perceptions and regulations to the way aquatic systems actually change and evolve through time will be a major challenge in the future.

    Full Text Available Interest in social entrepreneurship is growing widely not only in Brazil but in the world. Several developed countries have stepped forward to develop policies to support this area not only as a tool to fulfill the government failures such as poverty, health, education, unemployment among others, but also because of all the benefits that social enterprises have in relation to society. However, it is possible to identify a lack of political support for social entrepreneurship in Brazil. Given the needs in the Brazilian context of improvements in several areas where the state can not cover actions in their entirety as social exclusion, income distribution and especially professionalization of youth and creating jobs, we need a deep analysis of how social entrepreneurship can act as a modifying element of this scenario. Thus, with Brazil a country developing rapidly, it is important to verify public policies that support social entrepreneurship in already developed countries and carry out studies on the suitability and applicability of these policies in the Brazilian reality. Thus, this paper aims to study the trends of social entrepreneurship in some developed countries as well as analyzing public policies implemented by these countries, and considering the Brazilian context, present some policy proposals to support social entrepreneurship in Brazil.

    Physical inactivity is a significant public health problem in Brazil that may be addressed by partnerships and networks. In conjunction with Project GUIA (Guide for Useful Interventions for Physical Activity in Brazil and Latin America), the aim of this study was to conduct a social network analysis of physical activity in Brazil. An online survey was completed by 28 of 35 organizations contacted from December 2008 through March 2009. Network analytic methods examined measures of collaboration, importance, leadership, and attributes of the respondent and organization. Leadership nominations for organizations studied ranged from 0 to 23. Positive predictors of collaboration included: south region, GUIA membership, years working in physical activity, and research, education, and promotion/practice areas of physical activity. The most frequently reported barrier to collaboration was bureaucracy. Social network analysis identified factors that are likely to improve collaboration among organizations in Brazil.

    Many ecosystems continue to experience rapid transformations due to processes like land use change and resource extraction. A systems approach to maintaining natural resources focuses on how interactions and feedbacks among components of complex social-ecological systems generate social and ecological outcomes. In recreational fisheries, residential shoreline development and fish stocking are two widespread human behaviors that influence fisheries, yet emergent social-ecological outcomes from these potentially interacting behaviors remain under explored. We applied a social-ecological systems framework using a simulation model and empirical data to determine whether lakeshore development is likely to promote stocking through its adverse effects on coarse woody habitat and thereby also on survival of juvenile and adult fish. We demonstrate that high lakeshore development is likely to generate dependency of the ecosystem on the social system, in the form of stocking. Further, lakeshore development can interact with social-ecological processes to create deficits for state-level governments, which threatens the ability to fund further ecosystem subsidies. Our results highlight the value of a social-ecological framework for maintaining ecosystem services like recreational fisheries. © 2016 by the Ecological Society of America.

    2015-06-01

    Full Text Available Social scientists, and scholars in related interdisciplinary fields, have critiqued resilience thinking's oversimplification of social dimensions of coupled social-ecological systems. Resilience scholars have countered with "where is the ecology" in social analyses? My aim is to contribute to current efforts to strengthen inter- and transdisciplinary debate and inquiry between the social-ecological resilience community and the social sciences. I synthesize three social science perspectives, which stress the complex, dynamic, and multiscalar interconnections between the biophysical and social realms in explaining social-environmental change, and which place both the social and ecology centre stage in their analyses: materio-spatial world systems analysis, critical realist political ecology, and actor-network theory. By integrating, in a nondeterministic and nonessentialist manner, the biophysical environment into social inquiries (integrative approaches or by altogether abolishing the ecology/nature and human/culture divide (hybrid perspectives, these three social-science perspectives are well placed to foster stronger inter- and transdisciplinary ties with social-ecological resilience. Materio-spatial world systems analysis is highly compatible with resilience thinking. The emphasis on world systems structures and processes offers the potential to enrich resilience analyses of global environmental change, global governance and stewardship, planetary boundaries, and multiscale resilience. Critical realist political ecology offers avenues for more in-depth interdisciplinary inquiries around local/traditional/indigenous knowledge systems and power. It also challenges resilience scholars to incorporate critical analyses of resilience's core concepts and practices. Actor-network theory proposes a very different starting point for understanding and assessing social-ecological resilience. Its focus on "resilience-in-the-making" offers unique insights

    Protected areas (PAs) remain central to the conservation of biodiversity. Classical PAs were conceived as areas that would be set aside to maintain a natural state with minimal human influence. However, global environmental change and growing cross-scale anthropogenic influences mean that PAs can no longer be thought of as ecological islands that function independently of the broader social-ecological system in which they are located. For PAs to be resilient (and to contribute to broader social-ecological resilience), they must be able to adapt to changing social and ecological conditions over time in a way that supports the long-term persistence of populations, communities, and ecosystems of conservation concern. We extend Ostrom's social-ecological systems framework to consider the long-term persistence of PAs, as a form of land use embedded in social-ecological systems, with important cross-scale feedbacks. Most notably, we highlight the cross-scale influences and feedbacks on PAs that exist from the local to the global scale, contextualizing PAs within multi-scale social-ecological functional landscapes. Such functional landscapes are integral to understand and manage individual PAs for long-term sustainability. We illustrate our conceptual contribution with three case studies that highlight cross-scale feedbacks and social-ecological interactions in the functioning of PAs and in relation to regional resilience. Our analysis suggests that while ecological, economic, and social processes are often directly relevant to PAs at finer scales, at broader scales, the dominant processes that shape and alter PA resilience are primarily social and economic.

    Social inclusion is an important goal for people with intellectual and developmental disabilities, families, service providers, and policymakers; however, the concept of social inclusion remains unclear, largely due to multiple and conflicting definitions in research and policy. We define social inclusion as the interaction between two major life domains: interpersonal relationships and community participation. We then propose an ecological model of social inclusion that includes individual, interpersonal, organizational, community, and socio-political factors. We identify four areas of research that our ecological model of social inclusion can move forward: (1) organizational implementation of social inclusion; (2) social inclusion of people with intellectual and developmental disabilities living with their families, (3) social inclusion of people along a broader spectrum of disability, and (4) the potential role of self-advocacy organizations in promoting social inclusion.

    This ecological study investigated the association between social and environmental inequities and dental caries among indigenous people in Brazil. Dental caries data were gathered from articles identified from electronic databases for the period between 2000 and 2007. Independent variables were obtained from the census of Health Information System for Sanitation Indigenous Populations. Multiple linear regression analysis was conducted to test the association between social and environmental characteristics and dental caries (DMFT index) according to the age group. Results were analyzed for 48 indigenous peoples from 19 selected studies. The occurrence of dental caries in particular age groups was inversely associated with the location of villages outside the Amazon region (12, 15 - 19, and 20 - 34 years), availability of electricity (15 - 19 and 20 - 34 years) and proportion of households covered with straw/thatch (20 - 34 years). The presence of schools was statistically associated with higher DMFT averages (15 - 19 and 20 - 34 years). It can be concluded that aspects of location and existing infrastructure in indigenous communities, which are linked to the availability of oral health services, are associated with the occurrence of dental caries in indigenous populations in Brazil.

  18. Transitions of social-ecological subsistence systems in the Arctic

    Full Text Available Transitions of social-ecological systems (SES expose governance systems to new challenges. This is particularly so in the Arctic where resource systems are increasingly subjected to global warming, industrial development and globalization which subsequently alter the local SES dynamics. Based on common-pool resource theory, we developed a dynamic conceptual model explaining how exogenous drivers might alter a traditional subsistence system from a provisioning to an appropriation actions situation. In a provisioning action situation the resource users do not control the resource level but adapt to the fluctuating availability of resources, and the collective challenge revolve around securing the subsistence in the community. An increased harvest pressure enabled by exogenous drivers could transform the SES to an appropriation action situation where the collective challenge has changed to avoid overuse of a common-pool resource. The model was used as a focal lens to investigate the premises for broad-scale transitions of subsistence-oriented SESs in Arctic Alaska, Canada and Greenland. We synthesized data from documents, official statistics and grey and scientific literature to explore the different components of our model. Our synthesis suggests that the traditional Arctic subsistence SESs mostly comply with a provisioning action situation. Despite population growth and available technology; urbanization, increased wage labor and importation of food have reduced the resource demand, and we find no evidence for a broad-scale transition to an appropriation action situation throughout the Western Arctic. However, appropriation ­challenges have emerged in some cases either as a consequence of commercialization of the resource or by severely reduced resource stocks due to various exogenous drivers. Future transitions of SESs could be triggered by the emergence of commercial local food markets and Arctic warming. In particular, Arctic warming is an

    2016-01-01

    Social interaction is an essential part of the human experience, and much work has been done to study it. However, several common approaches to examining social interactions in psychological research may inadvertently either unnaturally constrain the observed behaviour by causing it to deviate from naturalistic performance, or introduce unwanted sources of variance. In particular, these sources are the differences between naturalistic and experimental behaviour that occur from changes in visual fidelity (quality of the observed stimuli), gaze (whether it is controlled for in the stimuli), and social potential (potential for the stimuli to provide actual interaction). We expand on these possible sources of extraneous variance and why they may be important. We review the ways in which experimenters have developed novel designs to remove these sources of extraneous variance. New experimental designs using a 'two-person' approach are argued to be one of the most effective ways to develop more ecologically valid measures of social interaction, and we suggest that future work on social interaction should use these designs wherever possible.

    Full Text Available Diet and feeding ecology of the mutton snapper Lutjanus analis were investigated in the Abrolhos Bank, Eastern Brazil, the largest and richest coral reefs in the South Atlantic, where about 270 species of reef and shore fishes occur. To evaluate seasonal and ontogenetic shifts in the diet, specimens of L. analis were obtained through a fish monitoring program in four cities in southern Bahia State, from June 2005 to March 2007. Stomachs from 85 mutton snappers that ranged in size from 18.1 to 74.0 cm TL were examined. Prey were identified to the lowest possible taxon and assessed by the frequency of occurrence and volumetric methods. Variations in volume prey consumption were evaluated using non-metric multi-dimensional scaling ordination, analysis of similarity, and similarity percentage methods. Significant differences in diet composition among size classes were registered, whereas non significant differences between seasons were observed. Considering size-classes, food items consumption showed important variations: juveniles (50.1 cm TL consumed basically fish, mostly Anguiliformes. Lutjanus analis is an important generalist reef predator, with a broad array of food resources and ontogenetic changes in the diet. This snapper species plays an important role on the trophic ecology of the Abrolhos Bank coral reefs.Foram avaliadas a dieta e a ecologia alimentar da cioba Lutjanus analis no Banco dos Abrolhos, Leste do Brasil.

    Many ecosystems continue to experience rapid transformations due to processes like land use change and resource extraction. A systems approach to maintaining natural resources focuses on how interactions and feedbacks among components of complex social-ecological systems generate social and ecological outcomes. In recreational fisheries, residential shoreline development and fish stocking are two widespread human behaviors that influence fisheries, yet emergent social-ecological outcomes from these potentially interacting behaviors remain under explored. We applied a social-ecological systems framework using a simulation model and empirical data to determine whether lakeshore development is likely to promote stocking through its adverse effects on coarse woody habitat and thereby also on survival of juvenile and adult fish. We demonstrate that high lakeshore development is likely to generate dependency of the ecosystem on the social system, in the form of stocking. Further, lakeshore development can interact with social-ecological processes to create deficits for state-level governments, which threatens the ability to fund further ecosystem subsidies. Our results highlight the value of a social-ecological framework for maintaining ecosystem services like recreational fisheries.

    How to create and adjust governing institutions so that they align (fit) with complex ecosystem processes and structures across scales is an issue of increasing concern in conservation. It is argued that lack of such social-ecological fit makes governance and conservation difficult, yet progress in explicitly defining and rigorously testing what constitutes a good fit has been limited. We used a novel modeling approach and data from case studies of fishery and forest conservation to empirically test presumed relationships between conservation outcomes and certain patterns of alignment of social-ecological interdependences. Our approach made it possible to analyze conservation outcome on a systems level while also providing information on how individual actors are positioned in the complex web of social-ecological interdependencies. We found that when actors who shared resources were also socially linked, conservation at the level of the whole social-ecological system was positively affected. When the scales at which individual actors used resources and the scale at which ecological resources were interconnected to other ecological resources were aligned through tightened feedback loops, conservation outcome was better than when they were not aligned. The analysis of individual actors' positions in the web of social-ecological interdependencies was helpful in understanding why a system has a certain level of social-ecological fit. Results of analysis of positions showed that different actors contributed in very different ways to achieve a certain fit and revealed some underlying difference between the actors, for example in terms of actors' varying rights to access and use different ecological resources. © 2014 Society for Conservation Biology.

  9. Understanding social-ecological change and transformation through community perceptions of system identity

    Mark Andrachuk

    2015-12-01

    Full Text Available We developed an empirical approach to consider social-ecological system change and transformation by drawing on resource users' knowledge and perceptions. We applied this approach in the Cau Hai lagoon, a coastal area dominated by small-scale fisheries in central Vietnam. Nine focus groups with more than 70 fishers were used to gather information about key social-ecological system elements and interactions, historical social-ecological dynamics, and possible thresholds between distinct social-ecological system identities. The patterns of change in livelihoods and resource exploitation in the Cau Hai lagoon are similar to those seen in other coastal lagoon and small-scale fishery contexts. Our findings show some promise for the use of local knowledge and the perceptions of resource user communities to understand and characterize social-ecological transformations. Importantly, however, we also demonstrate how social-ecological transformations are complicated processes driven by many factors beyond the control of any singular individual or group. We argue that (1 the occurrence of social-ecological transformations can result in either positive or negative outcomes and (2 that we need to direct our thinking away from drawing tidy conclusions about if and when social-ecological transformations take place. Our research also encourages scholars to carefully consider how we frame the benefits of participatory, community-based governance initiatives. Importantly, we need to examine the ways that governance initiatives will be beneficial for some people and detrimental for others, and we need to be fully aware of locally contested interests and acknowledge competing priorities for fisheries management and human well-being. Community-oriented assessments informed by resilience thinking can help to open up questions about economic, political, cultural, and environmental aspects of undesirable path dependencies and traps.

  12. Social roles and performance of social-ecological systems: evidence from behavioral lab experiments

    Full Text Available Social roles are thought to play an important role in determining the capacity for collective action in a community regarding the use of shared resources. Here we report on the results of a study using a behavioral experimental approach regarding the relationship between social roles and the performance of social-ecological systems. The computer-based irrigation experiment that was the basis of this study mimics the decisions faced by farmers in small-scale irrigation systems. In each of 20 rounds, which are analogous to growing seasons, participants face a two-stage commons dilemma. First they must decide how much to invest in the public infrastructure, e.g., canals and water diversion structures. Second, they must decide how much to extract from the water made available by that public infrastructure. Each round begins with a 60-second communication period before the players make their investment and extraction decisions. By analyzing the chat messages exchanged among participants during the communication stage of the experiment, we coded up to three roles per participant using the scheme of seven roles known to be important in the literature: leader, knowledge generator, connector, follower, moralist, enforcer, and observer. Our study supports the importance of certain social roles (e.g., connector previously highlighted by several case study analyses. However, using qualitative comparative analysis we found that none of the individual roles was sufficient for groups to succeed, i.e., to reach a certain level of group production. Instead, we found that a combination of at least five roles was necessary for success. In addition, in the context of upstream-downstream asymmetry, we observed a pattern in which social roles assumed by participants tended to differ by their positions. Although our work generated some interesting insights, further research is needed to determine how robust our findings are to different action situations, such as

    2012-12-01

    Full Text Available Analysis of fit has focused on the macrolevel fit between social institutions and ecosystems, and bypassed the microlevel fit between individual cognition and its socio-material environment. I argue that the conceptualizations we develop about social-ecological systems and our position in them should be understood as ways for a fundamentally cognitive organism to adapt to particular social and ecological situations. Since at issue is our survival as a species, we need to better understand the structure and dynamics of fit between human cognition and its social-ecological environment. I suggest that the embodied cognition perspective opens up possibilities for "nudging" evolution through the conceptual integration of the cognitively attractive but ecologically unrealistic neoclassical economics, and the cognitively less attractive but ecologically more realistic adaptive cycle theory (panarchy. The result is a conceptually integrated model, the Roller Coaster Blend, which expresses in metaphorical terms why competitive individuals are better off cooperating than competing with each other in the face of absolute resource limits. The blend enables the reframing of messages about the limits of the social-ecological system in terms of growth rather than degrowth. This is cognitively appealing, as upward growth fires in our minds the neural connections of "more," "control", and "happy." The blend's potential for nudging behavior arises from its autopoietic characteristic: it can be both an account of the social-ecological system as an emergent structure that is capable of renewing itself, and a cognitive attractor of individuals whose recruitment reinforces the integrity of the social-ecological system.

    2011-06-01

    Full Text Available The "chestnut civilization" is often used to qualify agrarian inland Corsica. Based on a critical review of historical sources and research on present dynamics, we show how this "civilization" has built up on a long series of resistance and adaptation to external political forces, from Genovese and French domination up to the present period of independence claims. The construction of the castagnetu, the Corsican chestnut (Castanea sativa mill. forest, as a social-ecological system is based on a constantly evolving compromise between wild and domestic attributes, but also on socio-political resistance, incorporation, and innovation. We argue that the castagnetu's resilience, beyond its social-ecological qualities and its economic profitability, is closely linked to a constant incorporation of identity and cultural values into chestnut trees and gardens, but also to the role assigned to the castagnetu by its supporters in the political positioning of their relations to both central power and outside actors.

    2017-10-01

    Ecology is a science that studies the mutual interactions between organisms and their environment. The fundamental subject of interest in ecology is the individual. Topics of interest to ecologists include the diversity, distribution and number of particular organisms, as well as cooperation and competition between organisms, both within and among ecosystems. Today, ecology is a multidisciplinary science. This is particularly true when the subject of interest is the ecosystem or biosphere, which requires the knowledge and input of biologists, chemists, physicists, geologists, geographists, climatologists, hydrologists and many other experts. Ecology is applied in a science of restoration, repairing disturbed sites through human intervention, in natural resource management, and in environmental impact assessments.

    In addition to understanding Brazilian policies and currently utilized methodologies, the measurement of the impacts of deforestation is essential for enhancing techniques to reduce deforestation in the future. Adverse impacts of deforestation include biodiversity loss, increased carbon dioxide emissions, and a reduced rate of evapotranspiration, all of which contribute directly or indirectly to global warming. With the continual growth in population in developing countries such as Brazil, increased demands are placed on infrastructural development and food production. As a result, forested areas are cleared for agricultural production. Recently, exploration for hydrocarbons in Western Brazil has also intensified as a means to stimulate the economy, as abundant oil and gas is believed to be found in these regions. Unfortunately, hydrocarbon-rich regions of Western Brazil are also home to thousands of species. Many of these regions are as of yet untapped but are at risk of ecological disruption as a result of impending human activity. This project utilized Landsat 5 TM to monitor deforestation in a subsection of the Brazilian states of Rondônia and Amazonas. A risk map identifying areas susceptible to future deforestation, based on factors such as proximity to roads, bodies of water, cities, and proposed hydrocarbon activities such as pipeline construction, was created. Areas at higher risk of clearance were recommended to be a target for enhanced monitoring and law enforcement. In addition, an importance map was created based on biodiversity and location of endangered species. This map was used to identify potential areas for future protection. A Chinese-Brazilian satellite, CBERS 2B CCD was also utilized for comparison. The NDVI model was additionally replicated in Quantum GIS, an open source software, so that local communities and policymakers could benefit without having to pay for expensive ArcGIS software. The capabilities of VIIRS were also investigated to

    Full Text Available The main objective of this study was to examine the natural history and the ecology of the species that constitute a snake assemblage in the Atlantic Rainforest, at Núcleo Picinguaba, Parque Estadual da Serra do Mar, located on the northern coast of the state of São Paulo, southeastern Brazil. The main aspects studied were: richness, relative abundance, daily and seasonal activity, and substrate use. We also provide additional information on natural history of the snakes. A total of 282 snakes, distributed over 24 species, belonging to 16 genera and four families, has been found within the area of the Núcleo Picinguaba. Species sampled more frequently were Bothrops jararaca and B. jararacussu. The methods that yielded the best results were time constrained search and opportunistic encounters. Among the abiotic factors analyzed, minimum temperature, followed by the mean temperature and the rainfall are apparently the most important in determining snake abundance. Most species presented a diet concentrated on one prey category or restricted to a few kinds of food items. The large number of species that feed on frogs points out the importance of this kind of prey as an important food resource for snakes in the Atlantic Rainforest. Our results indicate that the structure of the Picinguaba snake assemblage reflects mainly the phylogenetic constraints of each of its lineages.O principal objetivo deste estudo foi obter informações sobre a história natural e a ecologia das espécies que compõem uma taxocenoses de serpentes da Mata Atlântica, no Núcleo Picinguaba do Parque Estadual da Serra do Mar, localizado no litoral norte do estado no Estado de São Paulo, sudeste do Brasil.

    Resource management boundaries seldom align with environmental systems, which can lead to social and ecological problems. Mapping and analyzing how resource management organizations in different areas collaborate can provide vital information to help overcome such misalignment. Few quantitative approaches exist, however, to analyze social collaborations alongside environmental patterns, especially among local and regional organizations (i.e., in multilevel governance settings). This paper develops and applies such an approach using social-ecological network analysis (SENA), which considers relationships among and between social and ecological units. The framework and methods are shown using an estuary restoration case from Puget Sound, United States. Collaboration patterns and quality are analyzed among local and regional organizations working in hydrologically connected areas. These patterns are correlated with restoration practitioners' assessments of the productivity of their collaborations to inform network theories for natural resource governance. The SENA is also combined with existing ecological data to jointly consider social and ecological restoration concerns. Results show potentially problematic areas in nearshore environments, where collaboration networks measured by density (percentage of possible network connections) and productivity are weakest. Many areas also have high centralization (a few nodes hold the network together), making network cohesion dependent on key organizations. Although centralization and productivity are inversely related, no clear relationship between density and productivity is observed. This research can help practitioners to identify where governance capacity needs strengthening and jointly consider social and ecological concerns. It advances SENA by developing a multilevel approach to assess social-ecological (or social-environmental) misalignments, also known as scale mismatches.

  19. Toward a Network Perspective of the Study of Resilience in Social-Ecological Systems

    2006-06-01

    Full Text Available Formal models used to study the resilience of social-ecological systems have not explicitly included important structural characteristics of this type of system. In this paper, we propose a network perspective for social-ecological systems that enables us to better focus on the structure of interactions between identifiable components of the system. This network perspective might be useful for developing formal models and comparing case studies of social-ecological systems. Based on an analysis of the case studies in this special issue, we identify three types of social-ecological networks: (1 ecosystems that are connected by people through flows of information or materials, (2 ecosystem networks that are disconnected and fragmented by the actions of people, and (3 artificial ecological networks created by people, such as irrigation systems. Each of these three archytypal social-ecological networks faces different problems that influence its resilience as it responds to the addition or removal of connections that affect its coordination or the diffusion of system attributes such as information or disease.

    The first generation of research on animal social networks was primarily aimed at introducing the concept of social networks to the fields of animal behaviour and behavioural ecology. More recently, a diverse body of evidence has shown that social fine structure matters on a broader scale than initially expected, affecting many key ecological and evolutionary processes. Here, we review this development. We discuss the effects of social network structure on evolutionary dynamics (genetic drift, fixation probabilities, and frequency-dependent selection) and social evolution (cooperation and between-individual behavioural differences). We discuss how social network structure can affect important coevolutionary processes (host-pathogen interactions and mutualisms) and population stability.

    While many studies focus on how animals use public information, the dynamics of information spread and maintenance within groups, i.e. the 'ecology of information', have received little attention. Here we use fruitflies trained to lay eggs on specific substrates to implement information into groups containing both trained and untrained individuals. We quantify inter-individual interactions and then measure the spread of oviposition preference with behavioural tests. Untrained individuals increase their interactive approaches in the presence of trained individuals, and the oviposition preference transmission is directly proportional to how much trained and untrained individuals interact. Unexpectedly, the preference of trained individuals to their trained oviposition substrate decreases after interactions with untrained individuals, leading to an overall informational loss. This shows that social learning alone is not enough to support informational stability. © 2015 The Author(s) Published by the Royal Society. All rights reserved.

  7. Identifying Social-ecological Linkages to Develop a Community Fire Plan in Mexico

    Full Text Available Community forestry in rural Mexico presents a unique opportunity to study the linkages and feedback within coupled social-ecological systems due to the fact that agrarian or indigenous communities control approximately half of the national territory of Mexico. We used social and ecological diagnostic tools to develop a fire management strategy for a communal forest containing an endemic piñón pine species, Pinus cembroides subs. orizabensis, in the state of Tlaxcala, Mexico. The ecological diagnostic was done through fuel inventory, forest structure sampling, and fire behaviour modelling. The social assessment was conducted through household interviews, community workshops, and direct participant observation. The ecological fire hazard was quantified and coupled with the social assessment to develop a fire management plan. Vertical fuel continuity and flashy surface fuels created a high fire hazard. Modelled fire behaviour showed a rapid rate of spread and high flame lengths under multiple scenarios. Relative impunity for starting forest fires, poor community and inter-agency organisation, and lack of project continuity across organisational sectors appear to be the most significant social limiting factors for wildfire management. Combining both social and ecological diagnostic tools provides a comprehensive understanding of the actual risks to forests, and identifies realistic community-supported options for conservation on cooperatively managed lands.

    One of the key determinants of success in biodiversity conservation is how well conservation planning decisions account for the social system in which actions are to be implemented. Understanding elements of how the social and ecological systems interact can help identify opportunities for implementation. Utilizing data from a large-scale conservation initiative in southwestern of Australia, we explored how a social-ecological system framework can be applied to identify how social and ecological factors interact to influence the opportunities for conservation. Using data from semistructured interviews, an online survey, and publicly available data, we developed a conceptual model of the social-ecological system associated with the conservation of the Fitz-Stirling region. We used this model to identify the relevant variables (remnants of vegetation, stakeholder presence, collaboration between stakeholders, and their scale of management) that affect the implementation of conservation actions in the region. We combined measures for these variables to ascertain how areas associated with different levels of ecological importance coincided with areas associated with different levels of stakeholder presence, stakeholder collaboration, and scales of management. We identified areas that could benefit from different implementation strategies, from those suitable for immediate conservation action to areas requiring implementation over the long term to increase on-the-ground capacity and identify mechanisms to incentivize implementation. The application of a social-ecological framework can help conservation planners and practitioners facilitate the integration of ecological and social data to inform the translation of priorities for action into implementation strategies that account for the complexities of conservation problems in a focused way. © 2016 Society for Conservation Biology.

    2015-01-01

    Over recent years, modelling approaches from nutritional ecology (known as Nutritional Geometry) have been increasingly used to describe how animals and some other organisms select foods and eat them in appropriate amounts in order to maintain a balanced nutritional state maximising fitness. These nutritional strategies profoundly affect the physiology, behaviour and performance of individuals, which in turn impact their social interactions within groups and societies. Here, we present a conceptual framework to study the role of nutrition as a major ecological factor influencing the development and maintenance of social life. We first illustrate some of the mechanisms by which nutritional differences among individuals mediate social interactions in a broad range of species and ecological contexts. We then explain how studying individual- and collective-level nutrition in a common conceptual framework derived from Nutritional Geometry can bring new fundamental insights into the mechanisms and evolution of social interactions, using a combination of simulation models and manipulative experiments.

    Wilson, Rhonda L; Wilson, G Glenn; Usher, Kim

    2015-09-01

    The mental health of people in rural communities is influenced by the robustness of the mental health ecosystem within each community. Theoretical approaches such as social ecology and social capital are useful when applied to the practical context of promoting environmental conditions which maximise mental health helping capital to enhance resilience and reduce vulnerably as a buffer for mental illness. This paper explores the ecological conditions that affect the mental health and illness of people in rural communities. It proposes a new mental health social ecology framework that makes full use of the locally available unique social capital that is sufficiently flexible to facilitate mental health helping capital best suited to mental health service delivery for rural people in an Australian context.

    Guans are large frugivorous birds that inhabit Neotropical forests and play a fundamental role in seed dispersal and forest regeneration. Despite their ecological importance, the natural populations of these birds are increasingly threatened by deforestation and hunting pressure. The present study was conducted in the Araripe National Forest, Ceará (Brazil), with the objective of estimating population parameters (density and total population size) in the Rusty-margined Guan (Penelope superciliaris) and the White-browed Guan (Penelope jacucaca), as well as providing data on their feeding ecology, including seasonal variation and fruit morphology. The study was based on the monthly collection of data between November, 2011, and October, 2012. Population parameters were estimated using line transect surveys, while feeding ecology was studied by direct observation, and the collection of plant and fecal samples. The estimated population density of P. superciliaris was 19.17 individuals/km2 (CV=13.98%), with a mean of 0.13 sightings per 10 km walked. Penelope jacucaca was not encountered during the surveys. A total of 14 plant species were recorded in the diet of P. superciliaris, 12 by direct observation, and two from fecal samples. Fruit diameter varied from 6.3 ± 1.35 mm (Miconia albicans) to 29.9 ± 1.7 mm (Psidium sp.). Yellow was the most frequent fruit color (41.6%, n=5), with two species each (16.6%) providing black, green, and red fruits. Fleshy fruits of the baccate (50.0%, n=6) and drupe (33.3%, n=4) types were the most consumed. The data on population parameters and feeding ecology collected in the present study provide an important database for the development of effective management strategies by environmental agencies for the conservation of the populations of the two guan species.

    Full Text Available Faced with numerous seemingly intractable social and environmental challenges, many scholars and practitioners are increasingly interested in understanding how to actively engage and transform the existing systems holding such problems in place. Although a variety of analytical models have emerged in recent years, most emphasize either the social or ecological elements of such transformations rather than their coupled nature. To address this, first we have presented a definition of the core elements of a social-ecological system (SES that could potentially be altered in a transformation. Second, we drew on insights about transformation from three branches of literature focused on radical change, i.e., social movements, socio-technical transitions, and social innovation, and gave consideration to the similarities and differences with the current studies by resilience scholars. Drawing on these findings, we have proposed a framework that outlines the process and phases of transformative change in an SES. Future research will be able to utilize the framework as a tool for analyzing the alteration of social-ecological feedbacks, identifying critical barriers and leverage points and assessing the outcome of social-ecological transformations.

    Maria de Fatima P Militão de Albuquerque

    Full Text Available The microcephaly epidemic in Brazil generated intense debate regarding its causality, and one hypothesised cause of this epidemic, now recognised as congenital Zika virus syndrome, was the treatment of drinking water tanks with pyriproxyfen to control Aedes aegypti larvae. We present the results of a geographical analysis of the association between the prevalence of microcephaly confirmed by Fenton growth charts and the type of larvicide used in the municipalities that were home to the mothers of the affected newborns in the metropolitan region of Recife in Pernambuco, the state in Brazil where the epidemic was first detected. The overall prevalence of microcephaly was 82 per 10,000 live births in the three municipalities that used the larvicide Bti (Bacillus thuringiensis israelensis instead of pyriproxyfen, and 69 per 10,000 live births in the eleven municipalities that used pyriproxyfen. The difference was not statistically significant. Our results show that the prevalence of microcephaly was not higher in the areas in which pyriproxyfen was used. In this ecological approach, there was no evidence of a correlation between the use of pyriproxyfen in the municipalities and the microcephaly epidemic.

    2017-11-01

    Based on the provisions of corporate social responsibility and taking into account the specifics of Russian mining enterprises, the authors attempt to understand theoretically the corporate social and environmental responsibility in this paper. The study shows that the essence of the principles of socially responsible behavior has ancient roots, while the consumer's attitude towards nature begins only in the era of modern times. The genesis, evolution and transformation of social responsibility in Western countries in the twentieth century are traced. The necessity of taking into account the national social and cultural specifics of the domestic economy is substantiated instead of blind copying of foreign management practices. The difference in the formation of corporate social responsibility (CSR) abroad and in Russia is shown. The list of facts and factors contributing to the formation of CSR in Russian realities is given. With regard to the coal industry enterprises inconsistencies have been identified. Their overcoming will allow the enterprises formulating strategies for corporate social and environmental responsibility. The advantages of social and environmental responsibility in comparison with the legal one are presented. In conclusion, the authors summed up the theoretical interpretation of the object claimed in the introduction.

    2014-02-01

    Full Text Available The trend towards decline and stabilization of the AIDS epidemic in Brazil should be analyzed carefully, since aggregate data can mask regional or local inequalities in such a large and diverse country. The current study reevaluates the epidemic’s spatial dissemination and the AIDS-related mortality pattern in Brazil. The study considered all AIDS cases diagnosed in individuals over 18 years of age and living in Brazil, as well as AIDS deaths recorded in 1998-2008. Three-year moving average rates were estimated, and a spatial analysis was conducted using a local empirical Bayesian method. The epidemic was only found to be expanding in the North and Northeast regions, while declining in the rest of the country, especially in the Southeast. According to the findings, the apparent stabilization of AIDS mortality tends to mask regional disparities. Social determinants of health and regional disparities should be taken into account in program development and policymaking.

  9. Termite Communities in Sugarcane Plantations in Southeastern Brazil: an Ecological Approach

    Directory of Open Access Journals (Sweden)

    2015-08-01

    Full Text Available Termites are key components of soil fauna, playing an essential role in organic matter decomposition and nutrient cycling. However, they can cause significant economic losses in commercial plantations, such as sugar cane. Therefore, the correct identification of termite species is critical for pest control. Here, we evaluated the species richness, abundance and functional groups of termites in sugarcane plantations in 53 cities throughout the state of São Paulo, southeastern Brazil. We also analyzed the influence of macroclimatic variables on termite species distribution and functional groups. We found 22 taxa of two families, of which the most frequent species were Termitidae (96.51%. Within this family, Apicotermitinae had the highest frequency of occurrence (37.12%, followed by Termitinae (30.57%, Syntermitinae (27.95%, and Nasutitermitinae (0.8 %. The other family, Rhinotermitidae, had the lowest frequency (3.5%, being represented only by Heterotermes sulcatus Mathews. We classified Neocapritermes opacus Hagen (29.26%, Apicotermitinae sp.2 (24.89%, Cornitermes cumulans Kollar (13.10%, and Apicotermitinae sp.1 (6.99% as common taxa. The remaining 18 species were classified as rare. The most common functional group was humus-feeders (37%, followed by wood-feeders (34%, grass-litter feeders (25%, and intermediate feeders (4%. Climate influenced the distribution of common species, humus-feeders and grass-litter feeders. Regarding the pest status of termites in sugar cane plantations, we suggest that the exasperated use of pesticide in the last decades has reduced the abundance of species considered pests (e.g. Heterotermes and reinforce the importance of ecological approaches for determining the best pest control methods.

    Full Text Available Feeding habits of the midnight catfish Auchenipterichthys longimanus collected in rivers of the Caxiuanã National Forest (Eastern Amazonia, Brazil were investigated through the different hydrological periods (dry, filing, flood and drawdown. A total of 589 specimens were collected throughout seven samplings between July 2008 and July 2009, of which 74 were young males, 177 adult males, 89 young females and 249 adult females. The diet composition (Alimentary index - Ai% was analyzed by a non-metric multidimensional scaling (nMDS and by the analysis of similarity (ANOSIM, which included 37 items grouped into nine categories (Aquatic insects, Other aquatic invertebrates, Arthropods fragment, Fish, Plant fragment, Seeds, Terrestrial insects, Other terrestrial invertebrates, and Terrestrial vertebrates. We also calculated the niche breadth (Levins index and the repletion index (RI%. Differences in the diet composition between hydrological seasons were registered, primarily on diet composition between dry and flood season, but changes related with sex and maturity were not observed. The midnight catfish showed more specialists feeder habit in the flood period (March 2009 and more generalist habits in the dry season (November 2008. The amount of food eaten by A. longimanus based on repletion index (RI%, did not differ significantly from sex and maturity. However, we evidenced differences in RI% when comparing the studied months. These results provide important biological information about the trophic ecology of auchenipterids fish. In view of the higher occurrence of allochthonous items, this research also underpins the importance of riparian forests as critical environments in the maintenance and conservation of wild populations of fish in the Amazon basin.Neste estudo foram investigados os hábitos alimentares do bagre Auchenipterichthys longimanus coletados em rios da Floresta Nacional de Caxiuanã (Amazônia Oriental, Brasil ao longo de diferentes

    Efficiency and resistance to rapid change are hallmarks of both the judicial and legislative branches of the United States government. These defining characteristics, while bringing stability and predictability, pose challenges when it comes to managing dynamic natural systems. As our understanding of ecosystems improves, we must devise ways to account for the non-linearities and uncertainties rife in complex social-ecological systems. This paper takes an in-depth look at the Platte River basin over time to explore how the system's resilience—the capacity to absorb disturbance without losing defining structures and functions—responds to human driven change. Beginning with pre-European settlement, the paper explores how water laws, policies, and infrastructure influenced the region's ecology and society. While much of the post-European development in the Platte River basin came at a high ecological cost to the system, the recent tri-state and federal collaborative Platte River Recovery and Implementation Program is a first step towards flexible and adaptive management of the social-ecological system. Using the Platte River basin as an example, we make the case that inherent flexibility and adaptability are vital for the next iteration of natural resources management policies affecting stressed basins. We argue that this can be accomplished by nesting policy in a resilience framework, which we describe and attempt to operationalize for use across systems and at different levels of jurisdiction. As our current natural resources policies fail under the weight of looming global change, unprecedented demand for natural resources, and shifting land use, the need for a new generation of adaptive, flexible natural resources govern-ance emerges. Here we offer a prescription for just that, rooted in the social , ecological and political realities of the Platte River basin.

    The distribution of hookworm in schistosomiasis-endemic areas in Brazil was mapped based on climate suitability. Known biological requirements of hookworm were fitted to data in a monthly long-term normal climate grid (18 x 18 km) using geographical information systems. Hookworm risk models were produced using the growing degree day (GDD) water budget (WB) concept. A moisture-adjusted model (MA-GDD) was developed based on accumulation of monthly temperatures above a base temperature of 15 °C (below which there is no lifecycle progression of Necator americanus) conditional on concurrent monthly values (rain/potential, evapotranspiration) of over 0.4. A second model, designated the gradient index, was calculated based on the monthly accumulation of the product of GDD and monthly WB values (GDD x WB). Both parameters had a significant positive correlation to hookworm prevalence. In the northeastern part of Brazil (the Caatinga), low hookworm prevalence was due to low soil moisture content, while the low prevalence in southern Brazil was related to low mean monthly temperatures. Both environmental temperature and soil moisture content were found to be important parameters for predicting the prevalence of N. americanus.

    Child development and adaptation are best understood as biological and psychological individual processes occurring within the context of interconnecting groups, systems, and communities which, along with family, constitute the child's social ecology. This first of two articles describes the challenges and opportunities within a child's social ecology consisting of Micro-, Meso-, Exo-, and Macrosystems. The parent-child relationship, the most salient Microsystem influence in children's lives, plays an influential role in children's reactions to and recovery from disasters. Children, parents, and other adults participate in Mesosystem activities at schools and faith-based organizations. The Exosystem--including workplaces, social agencies, neighborhood, and mass media--directly affects important adults in children's lives. The Macrosystem affects disaster response and recovery indirectly through intangible cultural, social, economic, and political structures and processes. Children's responses to adversity occur in the context of these dynamically interconnected and interdependent nested environments, all of which endure the burden of disaster Increased understanding of the influences of and the relationships between key components contributes to recovery and rebuilding efforts, limiting disruption to the child and his or her social ecology A companion article (R. L. Pfefferbaum et al., in press) describes interventions across the child's social ecology.

    Full Text Available We reviewed the literature on leadership in linked social-ecological systems and combined it with the literature on institutional entrepreneurship in complex adaptive systems to develop a new theory of transformative agency in linked social-ecological systems. Although there is evidence of the importance of strategic agency in introducing innovation and transforming approaches to management and governance of such systems, there is no coherent theory to explain the wide diversity of strategies identified. Using Holling's adaptive cycle as a model of phases present in innovation and transformation of resilient social-ecological systems, overlaid by Dorado's model of opportunity context (opaque, hazy, transparent in complex adaptive systems, we propose a more coherent theory of strategic agency, which links particular strategies, on the part of transformative agents, to phases of system change.

  16. Learning as You Journey: Anishinaabe Perception of Social-ecological Environments and Adaptive Learning

    Full Text Available This paper explores the linkages between social-ecological resilience and adaptive learning. We refer to adaptive learning as a method to capture the two-way relationship between people and their social-ecological environment. In this paper, we focus on traditional ecological knowledge. Research was undertaken with the Anishinaabe people of Iskatewizaagegan No. 39 Independent First Nation, in northwestern Ontario, Canada. The research was carried out over two field seasons, with verification workshops following each field season. The methodology was based on site visits and transects determined by the elders as appropriate to answer a specific question, find specific plants, or locate plant communities. During site visits and transect walks, research themes such as plant nomenclature, plant use, habitat descriptions, biogeophysical landscape vocabulary, and place names were discussed. Working with elders allowed us to record a rich set of vocabulary to describe the spatial characteristics of the biogeophysical landscape. However, elders also directed our attention to places they knew through personal experiences and journeys and remembered from stories and collective history. We documented elders' perceptions of the temporal dynamics of the landscape through discussion of disturbance events and cycles. Again, elders drew our attention to the ways in which time was marked by cultural references to seasons and moons. The social memory of landscape dynamics was documented as a combination of biogeophysical structures and processes, along with the stories by which Iskatewizaagegan people wrote their histories upon the land. Adaptive learning for social-ecological resilience, as suggested by this research, requires maintaining the web of relationships of people and places. Such relationships allow social memory to frame creativity, while allowing knowledge to evolve in the face of change. Social memory does not actually evolve directly out of

    Full Text Available We describe some aspects of the ecology of Aparasphenodon brunoi, a species associated with bromeliads. We comment on the relationships of this species with bromeliad size, microhabitat use, diet and sexual dimorphism. This study was conducted on a Restinga habitat near Presidente Kennedy, state of Espírito Santo, southeastern coast of Brazil. When the animals were found inside the bromeliads, we measure bromeliad and head size of frogs. We analyzed stomach contents and determined the sex and reproductive condition. We found 17 individuals (58.6% in bromeliad leafs, six (20.7% in Cactaceae, three (10.3% in liana and three (10.3% on trunks. The correlation between head measurements and bromeliad size were high, indicating that animals apparently use bromeliads based on their size, which could be related to the minimization of water loss. The most common prey items were beetles, ants, and insect larvae, suggesting that the species is relatively generalist in prey consumption. Aparasphenodon brunoi showed significant sexual size and shape dimorphism with females having larger bodies than males (size and females having tibia, eye diameter and SVL larger than males (shape, but larger sample size and more detailed ecological and life history data are needed to elucidate the factors that have led to sexual size dimorphism.

    Full Text Available Some aspects of the ecology of the skink Mabuya agilis (Raddi, 1823 at the restinga habitat of Grumari, in Rio de Janeiro, Brazil are studied. Most of the lizards were first sighted on the ground, though a few were using perches (mainly cacti up to 30 cm high. Mean body temperature in activity was 33.1 ± 2.4ºC and was significantly correlated to air temperature. There was sexual dimorphism in size (snout-vent length - SVL, with females growing larger than males. Frequency of broken tails was high overall (83% and did not differ between sexes. Females and males are sexually mature at 49 mm and 47 mm SVL, respectively. Brood size averaged 3.2 ± 1.0 (range 1-5 and was positively and significantly related to female SVL (r = 0.65, p = 0.001. Relative clutch mass (RCM of seven gravid females averaged 0.250 ± 0.042, being relatively low compared to those of other congeners. The diet of M. agilis was composed basically of arthropods, with relatively large and soft-bodied arthropods such as spiders, caterpillars and homopterans being the most important prey. The results of our work confirm and expand the knowledge of ecological tendencies previously observed for M. agilis in other areas.

    Social-ecological systems are linked complex systems that represent interconnected human and biophysical processes evolving and adapting across temporal and spatial scales. In the real world, social-ecological systems pose substantial challenges for modeling. In this regard, Fuzzy Cognitive Maps (FCMs) have proven to be a useful method for capturing the functioning of this type of systems. FCMs are a semi-quantitative type of cognitive map that represent a system composed of relevant factors and weighted links showing the strength and direction of cause-effects relationships among factors. Therefore, FCMs can be interpreted as complex system structures or complex networks. In this sense, recent research has applied complex network concepts for the analysis of FCMs that represent social-ecological systems. Key to FCM the tool is its potential to allow feedback loops and to include stakeholder knowledge in the construction of the tool. Also, previous research has demonstrated their potential to represent system dynamics and simulate the effects of changes in the system, such as policy interventions. For illustrating this analysis, we have developed a series of participatory FCM for the study of the ecological and human systems related to biodiversity conservation in two case studies of the Amazonian region, the Bolivia lowlands of Guarayos and the Brazil Tapajos National forest. The research is carried out in the context of the EU project ROBIN1 and it is based on the development of a series of stakeholder workshops to analyze the current state of the socio-ecological environment in the Amazonian forest, reflecting conflicts and challenges for biodiversity conservation and human development. Stakeholders included all relevant actors in the local case studies, namely farmers, environmental groups, producer organizations, local and provincial authorities and scientists. In both case studies we illustrate the use of complex networks concepts, such as the adjacency

    People with physical disability report lower amounts of emotional and informational social support compared with other populations but it is unclear how influences at the broader societal level impact support in this population. To address this question, Berkman and Glass's social-ecological model was used to examine the influence of upstream factors on interpersonal support in people with physical disability. It was predicted that these factors would influence support even after controlling for the traditional measures linked to social support. 331 adult participants with physical disability (43% female; mean age = 42.7; 88% White) completed an online cross-sectional survey measuring types and sources of social support, social integration, disability impact in social domains, environmental barriers, and relevant psychosocial variables such as depression. A hierarchical linear regression analysis showed that level of disability, perceived tangible support, social integration, depressive symptoms, environmental barriers, occupational independence, and having family or friends as primary support sources were significantly associated with perceived support at the final step (R(2) = .60, F(22, 255) = 17.68, p social-ecological measures, environmental barriers and social integration, had the largest associations with interpersonal support. Results demonstrate the importance of measuring distinct support constructs and how the broader social environment may matter more in interpersonal support perceptions for people with disability than typical measures studied in the literature. Improving environmental factors will help improve social support. Copyright © 2015 Elsevier Inc. All rights reserved.

    Full Text Available Diversity and aspects of the ecology of social wasps (Vespidae, Polistinae in Central Amazonian "terra firme" forest. The knowledge of social wasp richness and biology in the Amazonian region is considered insufficient. Although the Amazonas state is the largest in the region, until now only two brief surveys were conducted there. Considering that the systematic inventory of an area is the first step towards its conservation and wise use, this study presents faunal data on social wasp diversity in a 25 km² area of "terra firme" (upland forest at the Ducke Reserve, Manaus, Amazonas, Brazil. Wasps were collected in the understory, following a protocol of three collectors walking along 60 trails 1,000 m in extension for 16 days between August and October 2010. Methods used were active search of individuals with entomological nets and nest collecting. Fifty-eight species of social wasps, allocated in 13 genera, were recorded; 67% of the collected species belong to Polybia, Agelaia and Mischocyttarus; other genera were represented by only four species or less. The most frequent species in active searches were Agelaia fulvofasciata (DeGeer, 1773, Agelaia testacea (Fabricius, 1804 and Angiopolybia pallens (Lepeletier, 1836. Twelve species were collected in nests. Prior to this study, 65 Polistinae species were deposited at the INPA Collection. Collecting in the study grid, an area not previously sampled for wasps, resulted in an increase of 25% species, and species richness was 86. According to the results, there is evidence that the diversity of social wasps at the Ducke Reserve is even higher, making it one of the richest areas in the Brazilian Amazonia.

    Full Text Available Panarchy provides a heuristic to characterize the cross-scale dynamics of social-ecological systems and a framework for how governance institutions should behave to be compatible with the ecosystems they manage. Managing for resilience will likely require reform of law to account for the dynamics of social-ecological systems and achieve a substantive mandate that accommodates the need for adaptation. In this paper, we suggest expansive legal reform by identifying the principles of reflexive law as a possible mechanism for achieving a shift to resilience-based governance and leveraging cross-scale dynamics to provide resilience-based responses to increasingly challenging environmental conditions.

    Long-term social security statistical forecasts produced and disseminated by the Brazilian government aim to provide accurate results that would serve as background information for optimal policy decisions. These forecasts are being used as support for the government's proposed pension reform that plans to radically change the Brazilian Constitution insofar as Social Security is concerned. However, the reliability of official results is uncertain since no systematic evaluation of these forecasts has ever been published by the Brazilian government or anyone else. This paper aims to present a study of the accuracy and methodology of the instruments used by the Brazilian government to carry out long-term actuarial forecasts. We base our research on an empirical and probabilistic analysis of the official models. Our empirical analysis shows that the long-term Social Security forecasts are systematically biased in the short term and have significant errors that render them meaningless in the long run. Moreover, the low level of transparency in the methods impaired the replication of results published by the Brazilian Government and the use of outdated data compromises forecast results. In the theoretical analysis, based on a mathematical modeling approach, we discuss the complexity and limitations of the macroeconomic forecast through the computation of confidence intervals. We demonstrate the problems related to error measurement inherent to any forecasting process. We then extend this exercise to the computation of confidence intervals for Social Security forecasts. This mathematical exercise raises questions about the degree of reliability of the Social Security forecasts.

    Quality of life is widely used as a measure of individual well-being in developed countries. Social quality (SQ), however, describes how favorable the socioenvironmental components are that impact the life chance of an individual. Despite the associations between SQ, including institutional capacity and citizen capacity, and other community indicators, the impact of SQ on community health status has not been fully examined. This study investigated the interrelationships among institutional capacity, citizen capacity, and their associations with community-level health indicators such as mortality and suicide among 230 local governments in South Korea. Under the principles of conceptual suitability, clarity, reliability, consistency, changeability, and comparability, a total of 81 SQ indicators were collected, and 19 indicators of the 81 indicators were selected. The 19 indicators were transformed by the imputation of missing values, standardization, and geographic information system transformation. It was found that the health outcome of local government was superior as social welfare, political participation, and education were higher. According to the result of the regression analysis based on the regional type, social welfare had the most influence on the health level of local government in both metropolises and small-/medium-sized cities. In addition, education and political participation had a positive effect on the health indicator of local metropolis government. However, SQ indicators did not have any meaningful influence at the county level. Therefore, small- and medium-sized cities need to promote the collective health of the local government through improving social welfare, and metropolises need to consider the complex relationship among other indicators while increasing the level of social welfare and education. Meanwhile, counties need to develop health indicators that reflect aged population characteristics and social environment of rural areas

    Child development and adaptation are best understood as biological and psychological individual processes occurring within the context of interconnecting groups, systems, and communities which, along with family, constitute the child’s social ecology. This first of two articles describes the challenges and opportunities within a child’s social ecology, consisting of Micro-, Meso-, Exo-, and Macrosystems. The parent-child relationship, the most salient Microsystem influence in children’s lives, plays an influential role in children’s reactions to and recovery from disasters. Children, parents, and other adults participate in Mesosystem activities at schools and faith-based organizations. The Exosystem—including workplaces, spcial agencies, neighborhood, and mass media—directly affects important adults in children’s lives. The Macrosystem affects disaster response and recovery indirectly through intangible cultural, social, economic, and political structures and processes. Children’s responses to adversity occur in the context of these dynamically interconnected and interdependent nested environments, all of which endure the burden of disaster. Increased understanding of the influences of and the relationships between key components contributes to recovery and rebuilding efforts, limiting disruption to the child and his or her social ecology. A companion article (R. L. Pfefferbaum et al., in press) describes interventions across the child’s social ecology. PMID:23156957

  10. Social-ecological Resilience and Biodiversity Conservation in a 900-year-old Protected Area

    Directory of Open Access Journals (Sweden)

    Adrian C. Newton

    2011-12-01

    Full Text Available Protected areas are increasingly being recognized as coupled social-ecological systems, whose effectiveness depends on their resilience. Here I present a historical profile of an individual case study, the New Forest (England, which was first designated as a protected area more than 900 years ago. Uniquely, a traditional pattern of land use has been maintained ever since, providing a rare opportunity to examine the resilience of an integrated social-ecological system over nine centuries. The New Forest demonstrates that over the long term, coupled social-ecological systems can be resilient to major internal and external shocks, including climate change, mass human mortality and war. Changes in governance had the greatest impact on the reserve itself, with two major crises identified in the mid-19th and 20th centuries. Resolution of these crises depended on the formation of alliances between local people and external partners, including the general public, a process that was supported by improvements in visitor access. Over a timescale of centuries, this social-ecological system has been highly dynamic in disturbance regimes but relatively stable in land use patterns. However, the factors underpinning resilience have changed over time. This case study suggests that for protected areas to be effective over the long term, social structures and institutions as well as environmental processes require adaptive capacity.

    With this commentary we make the case for an increased focus on the ecological validity of the measures used to assess aspects of human social functioning. Impairments in social functioning are seen in many types of psychopathology, negatively affecting the lives of psychiatric patients and those around them. Yet the neurobiology underlying abnormal social interaction remains unclear. As an example of human social neuroscience research with relevance to biological psychiatry and clinical psychopharmacology, this commentary discusses published experimental studies involving manipulation of the human brain serotonin system that included assessments of social behavior. To date, these studies have mostly been laboratory-based and included computer tasks, observations by others, or single-administration self-report measures. Most laboratory measures used so far inform about the role of serotonin in aspects of social interaction, but the relevance for real-life interaction is often unclear. Few studies have used naturalistic assessments in real life. We suggest several laboratory methods with high ecological validity as well as ecological momentary assessment, which involves intensive repeated measures in naturalistic settings. In sum, this commentary intends to stimulate experimental research on the neurobiology of human social interaction as it occurs in real life.

  13. Pathogens, disease, and the social-ecological resilience of protected areas

    2016-03-01

    Full Text Available It is extremely important for biodiversity conservation that protected areas are resilient to a range of potential future perturbations. One of the least studied influences on protected area resilience is that of disease. We argue that wildlife disease (1 is a social-ecological problem that must be approached from an interdisciplinary perspective; (2 has the potential to lead to changes in the identity of protected areas, possibly transforming them; and (3 interacts with conservation both directly (via impacts on wild animals, livestock, and people and indirectly (via the public, conservation management, and veterinary responses. We use southern African protected areas as a case study to test a framework for exploring the connections between conservation, endemic disease, and social-ecological resilience. We first define a set of criteria for the social-ecological identity of protected areas. We then use these criteria to explore the potential impacts of selected diseases (foot-and-mouth disease, anthrax, malaria, rabies, rift valley fever, trypanosomiasis, and canine distemper on protected area resilience. Although endemic diseases may have a number of direct impacts on both wild animals and domestic animals and people, the indirect pathways by which diseases influence social-ecological resilience also emerge as potentially important. The majority of endemic pathogens found in protected areas do not kill large numbers of wild animals or infect many people, and may even play valuable ecological roles; but occasional disease outbreaks and mortalities can have a large impact on public perceptions and disease management, potentially making protected areas unviable in one or more of their stated aims. Neighboring landowners also have a significant impact on park management decisions. The indirect effects triggered by disease in the human social and economic components of protected areas and surrounding landscapes may ultimately have a greater

    2011-05-01

    Often in land use evaluations, especially those in developing countries, only the financial aspect receives serious attention, while the social and ecological values are overlooked. This study compared the social and ecological values of four land use types (small-scale woodlot [SSW], boundary tree and shrub planting [BTP], homestead tree and shrub growing [HTG] and cereal farming [CF]) by a criteria-based scoring approach using a bao game. The impacts of local wealth status and proximity to a forest on the value the community renders to the land use types were also assessed. The value comparison, assessed by relative scoring, was accompanied by farmer's explanations to reveal the existing local knowledge about land use values. It was found that HTG ≥ SSW > BTP > CF for both social and ecological values. Though this trend applies for the medium and rich households, the poor ones chose SSW as the most valuable. With increasing distance from a forest, the social and ecological values of land uses increased. The accompanying scoring justifications indicated the existence of in-depth ecological knowledge, which conform to contemporary scientific reports. Generally, this study showed that social and ecological values, besides financial values, strongly influence farmer's decision in implementing various practices related to the land use types. Thus, such values are worth considering for a holistic understanding of the diverse benefits of land uses. Finally, the strong preference for tree and shrub-based land use types is a good opportunity for enhancing tree and shrub growing to minimize the major environmental problems (e.g., soil degradation, wood shortage and deforestation) in the central highlands of Ethiopia.

Material and methods. Questioning of students of 2 and 3 courses of agrarian (n=147and medical (n=147 of universities of Saratov age till 21 year in a gender ratio 1:1 is conducted. Results. Low ecological literacy of students of agrarian and medical universities, and also very "vague" ecological outlook is revealed. Gender distinctions in perception of environmental problems have been established. So, girls of medical university are more ecologically competent, than young men. Girls of both higher education institutions are more concerned about an ecological situation on the planet, but in too time a peculiar social and psychological mimicry which was shown in lack of correlation between the correct answers to questions of endoecology and value of a healthy lifestyle and a conduct of life of students was observed. Research has shown the high importance of occupations by physical culture and sport. The way of increase of popularity of tourism as sport is offered. Are given a work experience of section of sports tourism. Conclusion. The received results indicate the need of enhancement of methodology of teaching ecological bases of the higher school taking into account gender features of students.

    Full Text Available AIMS: In this study, the diversity of Ephemeroptera, Plecoptera, Trichoptera and Coleoptera communities was surveyed in the Toropi River basin, a watershed localized in a slope region, in southernmost Brazil. The influence of some local abiotic factors on the most common genera was also analyzed. METHODS: Samplings were conducted at 40 sites in 1st-4th order streams, along a short elevation gradient (70-500 m, with a Surber sampler. Water physico-chemical factors, as well as substrate type, were obtained at each site. RESULTS: At all, 5,320 specimens were collected, belonging to 18 families and 52 genera. The caddisflies Austrotinodes and Celaenotrichia, and an undescribed Elmidae, Genus M, are new records for the region. The caddisfly Smicridea was the most frequent genus in the study area. The mayflies Camelobaetidius, Paracloeodes and Americabaetis were influenced by stream order. Smicridea was related to air temperature, while the mayfly Thraulodes was influenced by high levels of electrical conductivity. CONCLUSIONS: The high diversity found in the study area, compared to other Brazilian regions, reflects the environmental heterogeneity in the region. These data show that hydrographic basins in slope areas from extreme Southern Brazil sustain high levels of diversity of aquatic insect communities.

    Several geomorphic features and palaeobiotic remains in now semi-arid northeastern Brazil indicate major palaeoenvironmental changes during past periods of increased rainfall. 230Th mass spectrometric ages of speleothems and travertines have allowed the determination of the timing and duration of wetter than present conditions. The data demonstrate that wet events have occurred throughout much of the Pleistocene, present dry conditions having been established at the end of the Younger Dryas. A markedly different fauna comprising megafaunal elements not adapted to the present low arboreal scrubland caatinga vegetation existed in the area. Palaeobotanical remains embedded in travertine indicate forested vegetation at these wetter intervals, suggesting that the caatinga was then replaced or mixed with a semi-deciduous forest. Due to the abundance of travertine sites containing fossil botanical remains in northeastern Brazil, it is believed that forest expansion occurred over large areas of the now semi-arid zone, showing that the long hypothesised forested links between biodiversity-rich Amazon and Atlantic rainforests may indeed have existed during these moister phases.

  3. The European Water Framework Directive: How Ecological Assumptions Frame Technical and Social Change

    Directory of Open Access Journals (Sweden)

    Patrick Steyaert

    2007-06-01

    Full Text Available The European Water Framework Directive (WFD is built upon significant cognitive developments in the field of ecological science but also encourages active involvement of all interested parties in its implementation. The coexistence in the same policy text of both substantive and procedural approaches to policy development stimulated this research as did our concerns about the implications of substantive ecological visions within the WFD policy for promoting, or not, social learning processes through participatory designs. We have used a qualitative analysis of the WFD text which shows the ecological dimension of the WFD dedicates its quasi-exclusive attention to a particular current of thought in ecosystems science focusing on ecosystems status and stability and considering human activities as disturbance factors. This particular worldview is juxtaposed within the WFD with a more utilitarian one that gives rise to many policy exemptions without changing the general underlying ecological model. We discuss these policy statements in the light of the tension between substantive and procedural policy developments. We argue that the dominant substantive approach of the WFD, comprising particular ecological assumptions built upon "compositionalism," seems to be contradictory with its espoused intention of involving the public. We discuss that current of thought in regard to more functionalist thinking and adaptive management, which offers greater opportunities for social learning, i.e., place a set of interdependent stakeholders in an intersubjective position in which they operate a "social construction" of water problems through the co-production of knowledge.

  4. Defining Acceptable Levels for Ecological Indicators: An Approach for Considering Social Values

    Ecological indicators can facilitate an adaptive management approach, but only if acceptable levels for those indicators have been defined so that the data collected can be interpreted. Because acceptable levels are an expression of the desired state of the ecosystem, the process of establishing acceptable levels should incorporate not just ecological understanding but also societal values. The goal of this research was to explore an approach for defining acceptable levels of ecological indicators that explicitly considers social perspectives and values. We used a set of eight indicators that were related to issues of concern in the Lake Champlain Basin. Our approach was based on normative theory. Using a stakeholder survey, we measured respondent normative evaluations of varying levels of our indicators. Aggregated social norm curves were used to determine the level at which indicator values shifted from acceptable to unacceptable conditions. For seven of the eight indicators, clear preferences were interpretable from these norm curves. For example, closures of public beaches because of bacterial contamination and days of intense algae bloom went from acceptable to unacceptable at 7-10 days in a summer season. Survey respondents also indicated that the number of fish caught from Lake Champlain that could be safely consumed each month was unacceptably low and the number of streams draining into the lake that were impaired by storm water was unacceptably high. If indicators that translate ecological conditions into social consequences are carefully selected, we believe the normative approach has considerable merit for defining acceptable levels of valued ecological system components.

    Full Text Available The Focus on Social Marketing: An analysis of the governmental campaigns about donation of organs in Brazil. Currently in Brazil the demand of organ donation is higher than the offer of them. Although the relevant legislation, which is identified in the country is a high demand of people waiting for a compatible organ donor and , on the other hand, a low supply of possible potential donors. Before this situation, the following research has as an objective to analyze the perspective of donors and potential organ donors in the state of Minas Gerais, Brazil concerning social marketing strategies used by the government. To do so, a research in quantitative and qualitative approach was done. The data in the quantitative part was collected directly through a survey done with 412 individuals and for the qualitative part, 23 semi-structured interviews with people directly involved in the process of organ donation were held. The results indicate that one of the main factors which interfere negatively in the intention of donating organs is related to safety matters. It emphasizes, still, a low perception concerning the efficiency of social marketing campaigns towards organ donation. Yet, according to the interviewees , such campaigns should merge calls negative and positive in order to provide individuals in addition to the emotional awareness , emotional or cognitive imbalances.

  7. Expansion of sugarcane ethanol production in Brazil: environmental and social challenges.

    2008-06-01

    Several geopolitical factors, aggravated by worries of global warming, have been fueling the search for and production of renewable energy worldwide for the past few years. Such demand for renewable energy is likely to benefit the sugarcane ethanol industry in Brazil, not only because sugarcane ethanol has a positive energetic balance and relatively low production costs, but also because Brazilian ethanol has been successfully produced and used as biofuel in the country since the 1970s. However, environmental and social impacts associated with ethanol production in Brazil can become important obstacles to sustainable biofuel production worldwide. Atmospheric pollution from burning of sugarcane for harvesting, degradation of soils and aquatic systems, and the exploitation of cane cutters are among the issues that deserve immediate attention from the Brazilian government and international societies. The expansion of sugarcane crops to the areas presently cultivated for soybeans also represent an environmental threat, because it may increase deforestation pressure from soybean crops in the Amazon region. In this paper, we discuss environmental and social issues linked to the expansion of sugarcane in Brazil for ethanol production, and we provide recommendations to help policy makers and the Brazilian government establish new initiatives to produce a code for ethanol production that is environmentally sustainable and economically fair. Recommendations include proper planning and environmental risk assessments for the expansion of sugarcane to new regions such as Central Brazil, improvement of land use practices to reduce soil erosion and nitrogen pollution, proper protection of streams and riparian ecosystems, banning of sugarcane burning practices, and fair working conditions for sugarcane cutters. We also support the creation of a more constructive approach for international stakeholders and trade organizations to promote sustainable development for biofuel

    Full Text Available This text identifies continuities and changes in the Brazilian social protection system during the Lula Government (2003-2006. It analyzes the expectations following the re-election of the president, the criticisms made of his government and then identifies the changes that occurred and those necessary in its trajectory. Conducting a review of the Lula Government is not an easy task, for a number of reasons. These include the disappointment of some intellectuals in light of their frustration as current or former members or sympathizers of the Workers Party (PT, the president's party; the risk of mistakes in the analysis and their consequent use by those who have personal, professional and social plans and space available to exploit the issue. Nevertheless, some elements are presented, seeking a better understanding of the current administration.

    2006-06-01

    Full Text Available The lakes in the northern highlands of Wisconsin, USA, the lakes and wetlands of Kristianstads Vattenrike in southern Sweden, and the Everglades of Florida, USA, provide cases that can be used to compare the linkages between ecological resilience and social dynamics. The erosion of ecological resilience in aquatic and wetland ecosystems is often a result of past management actions and is manifest as a real or perceived ecological crisis. Learning is a key ingredient in response to the loss of ecological resilience. Learning is facilitated through networks that operate in distinct arenas and are structured for dialogue, synthesis, and imaginative solutions to chart alternative futures. The networks also help counter maladaptive processes such as information control or manipulation, bureaucratic inertia, or corruption. The networks help create institutional arrangements that provide for more learning and flexibility and for the ability to change. Trust and leadership appear to be key elements for adaptability and transformability.

    The development process has resulted in deforestation. A comprehensive study is needed to obtain an objective solution by integrating the ecological dimension and human dimension. This study was conducted within Balai Raja Wildlife Reserve (BRWR), Bengkalis Regency, Riau Province, Indonesia. We used the social-ecological systems (SES) approach based on local characteristics, categorized into ecological status, social status and actors. Each factoris ranked using Multi-Dimensional Scaling (MDS).BRWR sustainability levels are in moderate condition. The ecological dimension is in a less sustainable state, with leverage: (1) forest conversion; (2) local ecological knowledge; (3) high conservation value. The social dimension is in a less sustainable state, with leverage: (1) community empowerment; (2) social conflict; (3) participation in landscape management. Dimensions actors are on a fairly sustainable status, with leverage: (1) institutional interaction; (2) stakeholder’s commitment; (3) law enforcement. We recommend strengthening community empowerment, local ecological knowledge, interaction, and stakeholder commitment

  16. Energy policy, social exclusion and sustainable development: The biofuels and oil and gas cases in Brazil

    Energy Technology Data Exchange (ETDEWEB)

    Hall, Jeremy; Matos, Stelvia; Silvestre, Bruno

    2010-09-15

    Recent Brazilian policies have encouraged impoverished communities to participate in the country's growing energy industry. This paper explores the country's attempts to encourage such participation within the oil and gas and biofuels sectors. Our research is based on interviews with industry executives, policymakers, non-governmental organizations and farmers conducted between 2005-2009 in Brazil, an emerging energy leader, yet a country grappling with social exclusion. We propose that some sectors have a propensity to be exclusive due to technological complexity, whereas other sectors, although less complex, tend to economize at the expense of social programs. We conclude with managerial and policy implications.

    2016-10-01

    Approaches to managing inland fisheries vary between systems and regions but are often based on large-scale marine fisheries principles and thus limited and outdated. Rarely do they adopt holistic approaches that consider the complex interplay among humans, fish, and the environment. We argue that there is an urgent need for a shift in inland fisheries management towards holistic and transdisciplinary approaches that embrace the principles of social-ecological systems at the watershed scale. The interconnectedness of inland fisheries with their associated watershed (biotic, abiotic, and humans) make them extremely complex and challenging to manage and protect. For this reason, the watershed is a logical management unit. To assist management at this scale, we propose a framework that integrates disparate concepts and management paradigms to facilitate inland fisheries management and sustainability. We contend that inland fisheries need to be managed as social-ecological watershed system (SEWS). The framework supports watershed-scale and transboundary governance to manage inland fisheries, and transdisciplinary projects and teams to ensure relevant and applicable monitoring and research. We discuss concepts of social-ecological feedback and interactions of multiple stressors and factors within/between the social-ecological systems. Moreover, we emphasize that management, monitoring, and research on inland fisheries at the watershed scale are needed to ensure long-term sustainable and resilient fisheries. Copyright © 2016.

    The concept of the Social-Ecological System (SES) of the coastal region, can be found in the seagrass ecosystem in the Kotania Bay Waters. Seagrass ecosystem as one of the productive ecosystem is part of an ecological system that can influence and influenced social system, in this case by people living around the seagrass ecosystem. This aim to estimating the socio-ecological vulnerability system of the seagrass ecosystem in the Kotania Bay Waters, the Linkage Matrix is used (de Chazal et al., 2008). This linkage matrix was created to determine the perception and understanding of the community on the ecosystem services provided by the seagrass ecosystem through the appraisal of various stakeholders. The results show that social values are rooted in the public perception of ecosystem goods and services, which are rarely considered. The ecological and economic value of natural resources is increasingly being used to determine the priority areas in the planning and management of coastal areas. The social value that exists in natural resources is highly recognized in conservation.

    2017-12-13

    Natural habitat destruction and fragmentation generate a time-delayed loss of species and associated ecosystem services. As social-ecological systems (SESs) depend on a range of ecosystem services, lagged ecological dynamics may affect their long-term sustainability. Here, we investigate the role of consumption changes for sustainability, under a time-delayed ecological feedback on agricultural production. We use a stylized model that couples the dynamics of biodiversity, technology, human demography and compliance with a social norm prescribing sustainable consumption. Compliance with the sustainable norm reduces both the consumption footprint and the vulnerability of SESs to transient overshoot-and-collapse population crises. We show that the timing and interaction between social, demographic and ecological feedbacks govern the transient and long-term dynamics of the system. A sufficient level of social pressure (e.g. disapproval) applied on the unsustainable consumers leads to the stable coexistence of unsustainable and sustainable or mixed equilibria, where both defectors and conformers coexist. Under bistability conditions, increasing extinction debts reduces the resilience of the system, thus favouring abrupt regime shifts towards unsustainable pathways. Given recent evidence of large extinction debts, such results call for farsightedness and a better understanding of time delays when studying the sustainability of coupled SESs. © 2017 The Author(s).

    Full Text Available We examined floristic patterns of ten seasonal semideciduous forest sites in southeastern Brazil and conducted a central sampling of one hectare for each site, where we took samples and identified all individual living trees with DBH (diameter at breast height, 1.30 m ≥4.8 cm. Arboreal flora totaled 242 species, 163 genera, and 58 families. Fabaceae (38 species and Myrtaceae (20 species were families with the largest number of species. Only Copaifera langsdorffii and Hymenaea courbaril occurred at all sites. Multivariate analysis (detrended correspondence analysis and cluster analysis using two-way indicator species analysis (TWINSPAN indicated the formation of a group containing seven fragments in which Siparuna guianensis was the indicator species. This analysis revealed that similarities between studied fragments were due mainly to the successional stage of the community.

  19. Social representation of Hansen's disease thirty years after the term 'leprosy' was replaced in Brazil

    2003-01-01

    Full Text Available Based on the theories of social representation (SC and Central Core (CC, a structural study was undertaken regarding the neologism hanseníase (Hansen's disease, the term adopted by Brazil's Ministry of Health in the 1970s. Carried out during 2001, this study interviewed eight hundred housewives residing in the Rio de Janeiro and Duque de Caxias municipalities. It found that Hansen's disease is part of a process of modernization of common thinking, anchored in the traditional representation of leprosy. This finding is understandable from the perspective that the central structure of a social representation has a historical determination, so short- and middle-term changes are not to be expected. Furthermore, there has been no ongoing investment in social marketing to make the new terminology more widely known. The authors discuss the relation between social representation and the concept of the history of mentalities.

  20. Conceptualizing, Observing, and Influencing Social-Ecological Transitions

    Full Text Available This article creates a meeting ground between two distinct and fairly elaborate research traditions dealing with social "transitions": the Dutch societal transitions management approach, and the Viennese sociometabolic transitions approach. Sharing a similar understanding of sustainability transitions - namely as major transformational changes of system characteristics - and a background epistemology of complex systems, autopoeisis, and evolutionary mechanisms, they address the subject from different angles: one approach asks how transformative changes happen and what they look like, and the other approach tries answer the question of how to bring them about. The Viennese approach is almost exclusively analytical and deals with a macro ("landscape" level of human history with a time scale of decades to centuries; the Dutch approach is based on intervention experiences and deals with a shorter time frame (decades of micro-meso-macro levels of industrial societies. From both their respective angles, they contribute to some of the key questions of sustainability research, namely: how can a transformative change toward sustainability be distinguished from other types of social change? By which mechanisms can obstacles, path dependencies, and adverse interests be overcome? And what are the key persistent problems that call for such a transition?

    The choices of energy sources gain relevance in the face of the ecological crisis which has a central questioning on the modes of production and consumption and that stems from a system which changes everything into merchandise. On one hand, brazilian electricity generation has the advantage of using clean energy in great part of its composition, at least in discourse. On the other hand, though, there are high social and environmental costs, especially for communities living near the regions where projects for the electricity sector are built. This research aimed to identify and analyse different modes society takes part in the process of choosing energy sources for electricity generation in Brazil. It discusses the links between the ecological crisis and the production of electrical energy; how the institutional mechanisms for social participation on issues related to the production of electric power in Brazil work; and, how civil society participates in environmental licensing in the National Environment Council (CONAMA). A set of related approaches to the nature of the ecological crisis and the forms of social participation was adopted in the theoretical framework and an analysis of the electric sector panorama in Brazil has been drawn up. In order to investigate the forms society participates in issues related to the composition of the brazilian electricity matrix, the methodology comprised a documentary analysis and a case study. They included three categories of actors: (1) CONAMA's councilors, (2) experts from the Field; and (3) actors involved in the diagnosis study, planning and management of the electricity sector. The research identified inconsistencies, ambiguities and other relevant issues about the participation of society in the production of electrical energy. Such issues are related to: deficiencies in the mechanisms for information access; lack of transparency and patterns in internal documents; lack of social participation in the elaboration

  2. Social structure emerges via the interaction between local ecology and individual behaviour.

    1. The formation of groups is a fundamental aspect of social organization, but there are still many questions regarding how social structure emerges from individuals making non-random associations. 2. Although food distribution and individual phenotypic traits are known to separately influence social organization, this is the first study, to our knowledge, experimentally linking them to demonstrate the importance of their interaction in the emergence of social structure. 3. Using an experimental design in which food distribution was either clumped or dispersed, in combination with individuals that varied in exploratory behaviour, our results show that social structure can be induced in the otherwise non-social European shore crab (Carcinus maenas). 4. Regardless of food distribution, individuals with relatively high exploratory behaviour played an important role in connecting otherwise poorly connected individuals. In comparison, low exploratory individuals aggregated into cohesive, stable subgroups (moving together even when not foraging), but only in tanks where resources were clumped. No such non-foraging subgroups formed in environments where food was evenly dispersed. 5. Body size did not accurately explain an individual's role within the network for either type of food distribution. 6. Because of their synchronized movements and potential to gain social information, groups of low exploratory crabs were more effective than singletons at finding food. 7. Because social structure affects selection, and social structure is shown to be sensitive to the interaction between ecological and behavioural differences among individuals, local selective pressures are likely to reflect this interaction. © 2011 The Authors.

    Full Text Available The abundance and distribution of ichthyoplankton and their relationships to current velocity, temperature, dissolved oxygen, pH and electrical conductivity of the water in the Anavilhanas Ecological Station, Negro River, Amazonas State, Brazil, were analyzed. Preferred microhabitats for spawning, dispersion and nursery were also verified. Sampling was undertaken during the falling water period of 2001 and the rising water period of 2002, in a section of 100 km subdivided into 5 subsections, with a total of 20 stations (5 beaches, 5 ravines, 5 channels, and 5 lake channels at night and during the day at the surface and at the bottom. 647 eggs and 4,187 larvae were captured, belonging to 10 families and four orders: Characiformes (6, Siluriformes (2, Perciformes (1, and Clupeiformes (1. Engraulidae (55.39%, Pimelodidae (30.45%, Auchenipteridae (5.23% and Sciaenidae (5.13% were the dominant families. The hierarchical statistical model (ANOVA with three factors (microhabitat, depth and period was applied to the environmental variables and the larval abundance, showing greater abundances of sciaenids in the ravines and lower abundances of engraulids in the channels. The highest captures were obtained at lower temperature values, at the bottom during the day and at the surface at night, suggesting an active larval behavior. The presence of the four larval development stages in all subsection for pimelodids and sciaenids, and in three subsections for engraulids, indicates that the Anavilhanas Ecological Station is an important spawning and nursery area for species of these groups in the Negro River. Larvae abundance of all characiform families was extremely low (from 0.1 to 1.17%, suggesting that they do not spawn in this system.

    Full Text Available ABSTRACT Presented is the first information on the ecological and reproductive aspects of the treefrog, Aparasphenodon brunoi Miranda-Ribeiro, 1920, living in ombrophilous forest areas of the Atlantic Rainforest, Brazil. We recorded the species’ daily activity and over the course of a year, population density during the year, microhabitat usage, diet, and some reproductive features (quantity, diameter and mean mass of oocytes, mean reproductive effort of female. Field sampling was conducted monthly from June 2015 to July 2016. Searches for treefrogs were systematic, using visual encounter surveys along 14 plots RAPELD long term research modules established in the forest. For each captured individual, we recorded the hour, microhabitat used, and perch height. The diet of the population was ascertained based on 15 individuals collected outside the study plot areas. Treefrogs used seven different types of microhabitats in the forest but the preferred microhabitats were tree-trunks and lianas. The amount of accumulated rainfall and air temperature interacted to explain the number of A. brunoi individuals active throughout the year. The reproductive strategy for females of this comparatively large arboreal frog in the ombrophilous forest is to produce clutches with a large number (900.8 ± 358.1 of relatively small-sized eggs. We conclude that in the ombrophious forest of the Vale Natural Reserve, A. brunoi is a nocturnal arboreal treefrog active throughout the year but activity increases during the wet season as a result of increased precipitation. In the forest, treefrogs tend to perch mainly on tree-trunks and lianas about 1 m above ground, where it feeds preferably on relatively large bodied arthropod prey. When living in the ombrophilous forest of the Atlantic rainforest, A. brunoi may change some features of its ecology (e.g. marked difference in the use of bromeliads compared to when living in restinga habitats.

    Full Text Available This study tested the ecological apparency hypothesis in the community of Barroquinha, in the municipality of Lagoa, Paraíba State, Brazil. We used the Use Value (UV by testing the information obtained through three types of calculations: UVgeneral, UVcurrent, and UVpotential. The botanical sampling was conducted in two areas of the community (Preserved - A1; Degraded - A2, and interviews were carried out with 66 people, who signed a Free and Transparent Consent form, required by the Research Ethics Committee. The Spearman's correlation test was performed to relate phytosociological data to ethnobotanical data. We used the Pearson Correlation to test the correlation between genders and the Use Values (UVs. Fifteen useful species were recorded in A1 and 16 species in A2. Positive correlations were found in both areas between species and the phytosociological data: in A1 between UVcurrent with basal area and dominance (p < 0.05 and in A2 between UVgeneral and UVcurrent with all parameters (p < 0.05. Only the forage category showed a positive correlation in A1 between UVpotential and density and frequency (p < 0.05. In A2, the fuel category was correlated with UVcurrent and basal area and dominance (p < 0.05. There was positive correlation between UVgeneral/UVcurrent, UVgeneral/UVpotential, UVcurrent/UVpotential (p < 0.0001. Men and women considered the same species as the most important (p < 0.0001. According to the results of this study, we can conclude that ecological apparency best explains the relationship between use and availability of species used for timber.

    Individuals with elevated social anxiety appear especially vulnerable to cannabis-related problems, yet little is known about the antecedents of cannabis-related behaviors among this high-risk population. The present study used ecological momentary assessment (EMA) to examine the relations among social anxiety, cannabis craving, state anxiety, situational variables, and cannabis use in the natural environment during ad-lib cannabis use episodes. Participants were 49 current cannabis users. During the two-week EMA period, social anxiety significantly interacted with cannabis craving to predict cannabis use both cross-sectionally and prospectively. Specifically, individuals with higher social anxiety and craving were most likely to use cannabis. There was a significant social anxiety X state anxiety X others’ use interaction such that when others were using cannabis, those with elevations in both trait social anxiety and state anxiety were the most likely to use cannabis.

    Human alteration of the global nitrogen cycle by agricultural activities has provided nutritious food to society, but also poses increasing threats to human and ecosystem health through unintended pollution. Managing nitrogen more efficiently in crop production is critical for addressing both food security and environmental challenges. Technologies and management practices have been developed to increase the uptake of applied nitrogen by crops. However, nitrogen use efficiency (NUE, yield per unit nitrogen input) is also affected by social and economic factors. For example, to maximize profit, farmers may change crop choice or their nitrogen application rate, both of which lead to a change in NUE. To evaluate such impacts, we use both theoretical and empirical approaches on micro (farm) and macro (national) scales: 1) We developed a bio-economic model (NUE3) on a farm scale to investigate how market signals (e.g. fertilizer and crop prices), government policies, and nitrogen-efficient technologies affect NUE. We demonstrate that if factors that influence nitrogen inputs (e.g. fertilizer-to-crop price ratios) are not considered, NUE projections will be poorly constrained. The impact of nitrogen-efficient technologies on NUE not only depends on how technology changes the production function, but also relies on the prices of the technologies, fertilizers, and crops. 2) We constructed a database of the nitrogen budget in crop production for major crops and major crop producing countries from 1961 to 2010. Using this database, we investigate historical trends of NUE and its relationship to agronomic, economic, social, and policy factors. We find that NUE in most developed countries follows a "U-shape" relationship with income level, consistent with the Environmental Kuznets Curve theory. According to the dynamics revealed in the NUE3 model, we propose three major pathways by which economic development affects NUE, namely consumption, technology, and public policy

  8. A “BRIC”-variety of capitalism and social inequality: The case of Brazil

    Full Text Available The focus of this contribution is on the mode of capitalism within the industrialized sectors of “emerging markets”. Particularly in the context of the rise of the BRIC (Brazil, Russia, India and China this question has gained considerable importance, also for the development of the world economy as a whole. The core question is whether the type of capitalism within these economies is similar to the capitalist variety of the triad, or diverges in more or less permanent ways. The article gives a preliminary answer to this question, by developing a rough sketch of a “BRIC” model of capitalism and illustrating this model with the case of Brazil. In terms of theory, the article extends the Comparative Capitalism (CC perspective to the BRICs. On the one side, the focus is on the classical questions of CC, i.e. the determinants of economic development and the differences to other types of capitalism, on the other side the relationship between these varieties and social inequality. It argues that the “state-permeated market economies” of the BRICs rely on clans as a mode of social coordination. As demonstrated by the case of Brazil, this type of capitalism can be quite successful, but is based on a highly unequal distribution of economic and political resources.

    Recognized as one of the world’s most vital natural and cultural resources, the Amazon faces a wide variety of threats from natural resource and infrastructure development. Within this context, rigorous scientific study of the region’s complex social-ecological system is critical to inform and direct decision-making toward more sustainable environmental and social outcomes. Given the Amazon’s tightly linked social and ecological components and the scope of potential development impacts, effective study of this system requires an easily accessible resource that provides a broad and reliable data baseline. This paper brings together multiple datasets from diverse disciplines (including human health, socio-economics, environment, hydrology, and energy) to provide investigators with a variety of baseline data to explore the multiple long-term effects of infrastructure development in the Brazilian Amazon.

    Research concerning the complex interplay between factors that contribute to poor social functioning in schizophrenia has been hampered by limitations of traditional measures, most notably the ecological validity and accuracy of retrospective self-report and interview measures. Computerized Ecological Momentary Assessment (EMAc) permits the real-time assessment of relationships between daily life experiences, thoughts, feelings, and behaviors. In the current study, EMAc was used to record daily social interactions, subjective performance appraisals of these interactions (e.g., "I succeeded/failed"; "I was liked/rejected"), and affect in 145 individuals with schizophrenia or schizoaffective disorder. Participants completed electronic questionnaires on a personal digital assistant (PDA) four times per day for one week. Time-lagged multilevel modeling of the data revealed that more positive interaction appraisals at any point in a day were associated with greater positive affect which, in turn, was a strong predictor of more social interactions over subsequent hours. Social functioning, therefore, was linked to positive performance beliefs about social interactions that were associated with greater positive affect. The findings suggest a useful treatment target for cognitive behavioral therapy and other psychosocial interventions that can be used to challenge defeatist beliefs and increase positive affect to enhance social functioning in schizophrenia.

    Network analysis is used to address diverse ecological, social, economic, and epidemiological questions, but few efforts have been made to combine these field-specific analyses into interdisciplinary approaches that effectively address how complex systems are interdependent and connected to one another. Identifying and understanding these cross-boundary connections improves natural resource management and promotes proactive, rather than reactive, decisions. This research had two main objectives; first, adapt the framework and approach of infectious disease network modeling so that it may be applied to the socio-ecological problem of spreading aquatic invasive species, and second, use this new coupled model to simulate the spread of the invasive Chinese mystery snail (Bellamya chinensis) in a reservoir network in Southeastern Nebraska, USA. The coupled model integrates an existing social network model of how anglers move on the landscape with new reservoir-specific ecological network models. This approach allowed us to identify 1) how angler movement among reservoirs aids in the spread of B. chinensis, 2) how B. chinensis alters energy flows within individual-reservoir food webs, and 3) a new method for assessing the spread of any number of non-native or invasive species within complex, social-ecological systems.

  13. Resilience Pivots: Stability and Identity in a Social-Ecological-Cultural System

    2014-03-01

    Full Text Available How is cultural resilience achieved in the face of significant social and ecological change? Is resilience compatible with changed structures, functions, and feedbacks as long as identity is maintained? The concept of cultural resilience has been less explored than its older siblings ecological resilience, social resilience, and social-ecological resilience. We seek to redress the balance, drawing from resilience thinking to examine how a New Zealand Māori tribal group of landowners retained strong cultural identity and connectedness to their land despite enduring significant changes in land use, economy, tenure, and governance. The landowners negotiated radical transformations in the ecology and land use of their home lands on terms that supported matters of cultural importance. The key resilience concepts of adaptation and transformation were helpful in analyzing the trajectory of change, but fell short of representing the elements of stability that supported the cultural resilience of the landowners. The concept of resilience pivots was designed to address this conceptual gap, and to offer another heuristic to resilience thinking by focusing on stability rather than change. Resilience pivots are those elements of a resilient system that remain stable despite adaptation or even transformation of other elements of that system, and in doing so support the maintenance of the system's distinctive identity.

    Access to medicines and the development of a strong national pharmaceutical industry are two longstanding pillars of health policy in Brazil. This is reflected in a clear emphasis by Brazil's Federal Government on improving access to medicine in national health plans and industrial policies aimed at promoting domestic pharmaceutical development. This research proposes that such policies may act as incentives for companies to pursue a strategic Corporate Social Responsibility (CSR) agenda. CSR that supports Governmental priorities could help companies to benefit significantly from the Governmental industrial policy. We sought to determine whether CSR activities of Brazilian pharmaceutical firms are currently aligned with the Federal Government's health prioritization. To do so we examined key Brazilian health related policies since 2004, including the specific priorities of Brazil's 2012-2015 Health Plan, and compared these with CSR initiatives that are reported on the websites of select pharmaceutical firms in Brazil. Brazil's national health plans and industrial policies demonstrated that the Federal Government has followed diverse approaches for improving access to medicines, including strengthening health care infrastructure, increasing transparency, and supporting product development partnerships. Case studies of six pharmaceutical firms, representing both public and private companies of varying size, support the perspective that CSR is a priority for firms. However, while many programs target issues such as health infrastructure, health care training, and drug donation, more programs focus on areas other than health and do not seem to be connected to Governmental prioritization. This research suggests that there are loose connections between Governmental priorities and pharmaceutical firm CSR. However, there remains a significant opportunity for greater alignment, which could improve access to medicines in the country and foster a stronger relationship between

    This article aims to systematize and analyze social data that reveal the dimension of racial inequalities in Brazil. The point of departure is that racial inequalities affect the capacity for integration of Blacks into Brazilian society and jeopardize the proposal to build a democratic society with equal opportunities for all. Such inequalities are present at different moments in the individual life cycle, beginning in childhood and continuing through school years, in access to urban infrastructure, and crystallizing in the labor market, consequently determining the income and living conditions of Afro-Brazilians as a whole. The article also analyzes the main positions in the political debate on racial inequalities in Brazil, identifying recent initiatives by both the Brazilian government and civil society to deal with racial discrimination and racial inequalities. The article concludes by identifying key challenges for health policy-makers in this context.

    Full Text Available Lontra longicaudis (Olfers, 1818 (Carnivora, Mustelidae is a semi-aquatic animal spread through the Central and South America, except in Chile. The implantation of a hydroelectric power plant along a river alters the dynamics of the watercourse, transforming a lotic environment into a lentic or semilotic one, what can damage the otter's feeding. From April 2008 to March 2009 we analysed the otter's food habits in lotic (streamlet and semilotic (hydroelectric reservoir environments of Paranapanema Valley, in southeastern Brazil. Aiming to compare the otter's diet of these two environments, we analyzed statistically the frequency of occurrence of main items in the scats. Fishes represent the base of the diet both in the reservoir and in the streamlet and, despite of the total otter's diet showing up similarities in the two environments, the results evidenced modifications on the fish species consumed between them. In the reservoir the otters ate more exotic fish Oreochromis niloticus (Linnaeus, 1758 probably because it is an easy capture prey in this place. The fact that the otters get established and feed in the reservoir doesn't mean that this structure is benefic to the species because the food supplied for it consists mainly of exotic fish species.

    Between January 1999 and December 2000, 876 bird specimens were captured in three different ecological environments from the Reinhard Maack Park, Curitiba, State of Paraná, southern Brazil. A total of 142 birds (16.2%) were infested with Amblyomma aureolatum (Pallas 1772) (N=699) and/or Ixodes auritulus Neumann, 1904 (N=18) ticks. Questing A. aureolatum nymphs (N=2) and adults (N=5) were also collected from the soil and the vegetation. None of the I. auritulus were collected off-host. We collected only immatures of A. aureolatum on birds, but all life stages of I. auritulus. The latter species was collected on Turdus rufiventris and on Synallaxis ruficapilla, which is herein recognized as a host of I. auritulus for the first time. Moreover, this is also the first report of A. aureolatum infesting birds, and 16 different bird species were found infested. It was observed that larval infestation was positively correlated with the dry and cold season, while nymphal infestation was positively correlated with the warm and rainy season. Although only 2-years worth of data is provided, our results suggest the infestation of birds by ticks was significantly higher at the biotopes formed by forest at its first stage of regeneration 'capoeira' and the original Araucaria forest habitat 'mata' than the ecotone between forest and urban areas 'peripheral area'.

    We studied the ectoparasitic bat flies of three phyllostomid vampire bat species. Bats were collected monthly from April 2004-March 2005 in caves within the Cafuringa Environmental Protection Area in the Federal District of Brazil. A total of 1,259 specimens from six species in the Streblidae family were collected from 332 bats. High host affinity from the sampled bat fly species and high prevalence of bat flies confirms the primary fly-host associations (Strebla wiedemanni, Trichobius parasiticus and Trichobius furmani with Desmodus, Trichobius diaemi and Strebla diaemi with Diaemus and T. furmani with Diphylla). Male flies outnumbered females in several associations. Some of the observed associations (e.g., Strebla mirabilis with Desmodus and S. mirabilis, Trichobius uniformis and S. wiedemanni with Diphylla) were inconclusive and the causes of the associations were unclear. There are several explanations for these associations, including (i) accidental contamination during sampling, (ii) simultaneous capture of several host species in the same net or (iii) genuine, but rare, ecological associations. Although various species of vampire bats share roosts, have similar feeding habits and are close phylogenetic relatives, they generally do not share ectoparasitic streblid bat flies. T. diaemi and S. diaemi associations with Diaemus youngi have not been previously reported in this region.

    Phlebotomines are invertebrate hosts of Leishmania genus species which are etiological agents of leishmaniases in humans and other mammals. Sandflies are often collected in entomological studies of caves both in the inner area and the adjacent environments. Caves are ecotypes clearly different from the external environment. Several caves have been opened to public visitation before any studies were performed and the places do not have scientific monitoring of the fauna, flora, geological and geographical characteristics. These events can lead to the loss of geological and biological information. Considering these aspects, this study aimed to describe the sand fly fauna, including the ecological features, in a limestone cave at the Speleological Province of Bambuí (Minas Gerais State, Brazil). A total of 8,354 specimens of sandflies belonging to 29 species were analyzed: Lutzomyia cavernicola (20%), Nyssomyia intermedia (15%), Martinsmyia oliveirai (13%), Evandromyia spelunca (12%), Evandromyia sallesi (11%), Migonemyia migonei (9%), Nyssomyia whitmani (9%), Sciopemyia sordellii (4%) and Lutzomyia longipalpis (2%). The others species represent 5% of the total. This manuscript presents data found on richness, diversity, evenness and seasonality, comparing the sand fly fauna trapped in the cave and its surroundings. PMID:24130847

    Full Text Available Abstract Aim: Seasonal patterns diatom community on Acrostichum danaeifolium were examined in a wetland in southern Brazil. Methods The adhered diatoms were removed from the plant, species identification and growth forms were performed, and determined physical-chemical parameters of water. Results In total, 96 taxa belonging to 46 genera were identified. Nitzschia frustulum, Pseudostaurosira brevistriata and Plagiogramma tenuissimum were abundant species. Distinct growth forms that formed low-and high-profile ecological guilds and a mobile guild were observed. Navicula and Nitzschia were the genera with the greatest number of species, and these diatoms formed mucilage tubes. The water temperature varied from 10-26 °C, the depth from 0.35-0.80 m, the transparency from 0.20-0.23 m, the flow from 9.4-42.12 m3 s–1, the pH from 7.08-8.89, the electrical conductivity from 0.65-15.83 mS cm–1, the total organic phosphorus from 0.03-0.11 mg L–1, and the total organic nitrogen from 0.29-0.49 mg L–1. In summer, marine species such as Thalassiosira eccentrica and Rhaphoneis castracanii were also present. Conclusions The high-profile guild prevailed in all seasons of the year, with higher number of growth forms in the guild in winter. The richness found on A. danaeifolium shows that this plant provide a favorable habitat for epiphytic diatoms in wetlands such as Lagoa Pequena.

    Full Text Available The Sundarban Mangrove Forest (SMF is an intricate ecosystem containing the most varied and profuse natural resources of Bangladesh. This study presents empirical research, based on primary and secondary data, regarding the social-ecological system (SES, social-ecological dynamics, different stakeholders and relevant management policies of small-scale or artisanal fisheries such as the SMF; showing how, despite extensive diversification, the livelihood activities of the artisanal fishers in the SMF all depend on the forest itself. Regardless of this critical importance of mangroves, however, deforestation continues due to immature death of mangroves, illegal logging, increased salinity, natural disasters and significant household consumption of mangrove wood by local people. As the mangroves are destroyed fish stocks, and other fishery resources are reduced, leading to moves of desperation among those whose livelihood has traditionally been fishing. The present study also considers several risks and shock factors in the fishers' livelihood: attacks by wild animals (especially tigers and local bandits, illness, natural disasters, river bank erosion, and the cost of paying off corrupt officials. The artisanal fishers of the SMF have adopted different strategies for coping with these problems: developing partnerships, violating the fisheries management laws and regulations, migrating, placing greater responsibility on women, and bartering fishing knowledge and information. This study shows how the social component (human, the ecological component (mangrove resources and the interphase aspects (local ecological knowledge, stakeholder's interest, and money lenders or middle man roles of the SMF as an SES are linked in mutual interaction. It furthermore considers how the social-ecological dynamics of the SMF have negative impacts on artisanal fishermen's livelihoods. Hence there is an urgency to update existing policies and management issues for the

    This study intends to give recommendations to the management of Paraty fishery in Brazil through an interplay of local and scientific knowledge. In particular, the objectives are the following: 1) to describe the Paraty fishery; 2) to compare the fishermen’s local ecological knowledge with recorded fish landings and previous studies in Paraty; 3) to combine the data on local fishing and on local/Caiçara livelihoods with the SES (social-ecological systems) Model. The methods include a systematic survey of fishing in Tarituba and Praia Grande, which are located in the northern end and the central part of the Paraty municipality, respectively. For four days each month, systematic data on catches at landing points were collected, as well as macroscopic gonad analysis data for the fishes Centropomus parallelus and C. undecimalis (snook, robalo), Epinephelus marginatus (grouper, garoupa), Scomberomorus cavalla (King mackerel, cavala), and Lutjanus synagris (Lane snapper, vermelho). Spring and summer are important seasons during which some species reproduce, and the integration of fishing periods for some target species could assist in fishing management through the use of closed seasons. Fishermen could obtain complementary earnings from tourism and from the “defeso system” (closed season including a salary payment) to conserve fishing stocks. The SES model facilitates an understanding of the historical context of fishing, its economic importance for local livelihoods, the constraints from conservation measures that affect fishermen, and the management processes that already exist, such as the defeso. If used to integrate fishing with complementary activities (tourism), such a system could improve the responsibility of fishermen regarding the conservation of fish stocks. PMID:22738073

    To identify the socioeconomic, demographic, operational, and health service-related factors associated with the occurrence of leprosy in a hyperendemic State in North Brazil. This is an ecological study based on secondary data from the Sistema de Informações de Agravos de Notificação in municipalities of the State of Tocantins from 2001 to 2012. Units of analysis were the 139 municipalities of the State. Negative binomial log linear regression models were used to estimate incidence rate ratios. In bivariate analysis, the incidence rate ratios were significantly higher for municipalities with higher income ratio of the poorest 20.0% (1.47; 95%CI 1.19-1.81) and better Municipal Human Development Index (1.53; 95%CI 1.14-2.06). In multivariate analysis, the incidence rate ratios were significantly higher in municipalities with higher proportion of immigrants (1.31; 95%CI 1.11-1.55) and higher proportion of households with waste collection (1.37; 95%CI 1.11-1.69). There was a significant reduction in the incidence rate ratio with increased coverage of the Bolsa Família Program (0.98; 95%CI 0.96-0.99). Control programs need to focus on activities in municipalities of greater social vulnerability with intersectoral investment for the improvement of the living conditions of the population.

    Full Text Available In this paper we will analyze the dynamics of a social-ecological system (SES, which requires an integrated understanding of both the interrelatedness of biophysical and socioeconomic components and the adaptive capacity of these system’s components to external drivers. Social-ecological resilience, the adaptive cycle metaphor and livelihood development are presented as the guiding conceptual framework to analyze local strategies, aiming towards the sustainable use of natural resources and to encourage the participation of the community in the management of ecosystem services, thereby improving human well-being. Furthermore, in the light of recurring unpredictable changes, adaptive capacity building and a high responsiveness to these changes may serve as fundamental assets to increase both ecological resilience, including the protection of biodiversity, and social resilience, including social and human capital and institutional capacity. An integrated analysis of SESs considers i the interplay of internal and external factors and their role in SES dynamics, ii potential thresholds whose crossing may shift the system into an undesirable state, and iii cross-scale spatial and temporal interactions. Ultimately, an SES approach favors ecosystem stewardship in that it enhances the sustainable use of natural resources and ecosystem services, and simultaneously resilient livelihood development.

    Despite a proliferation of research in interpersonal perception and aging, no research has identified the nature of the social and emotional perceptions made by aging individuals in everyday life. In this study, we aimed to identify the social ecological features that characterize everyday interpersonal perception across the adult lifespan. Three studies were conducted. Study 1 identified and compared the targets and locations of young, middle-age, and older adults' everyday interpersonal perceptions; these perceptions were categorized into types in Study 2. Study 3 applied these categorizations to identify and compare the social ecology surrounding aging individuals' interpersonal perceptions. Everyday interpersonal perceptions were directed toward familiar others and occurred in familiar locations, although the specific familiar targets and locations sometimes varied significantly with age. However, the types of perceptions made in everyday life did not vary significantly between age groups. Aging individuals make similar types of interpersonal judgments, but the targets and locations of these judgments may change with age. Future studies on interpersonal perception and aging will need to account for these features of the aging individual's social ecology to provide an accurate assessment of the aging process.

    Full Text Available Latin American and Caribbean (LAC countries are among the worlds' richest in marine biodiversity. Fish stocks in these regions are important for fishing communities, and fishing activities engage several million people. These fisheries depend on the natural services provided by a diverse range of marine social-ecological systems, but many LAC fisheries are in a degraded state, and concerns about overexploitation are widespread. With most fishery resources fully exploited or overexploited, opportunities for development lie primarily in restoring depleted stocks and using stocks more efficiently. The papers published in the Special Feature "Cooperation, Local Communities, and Marine Social-Ecological Systems: New Findings from Latin America" present a range of experiences with ecosystem stewardship in the region and highlight promising perspectives for the future. The Special Feature consists of papers that deal with new findings from case studies which show how cooperation is key for building resilience in LAC fisheries. These case studies illustrate the effects of different types of cooperation and the roles of diverse stakeholders (fishers, scientists, environmental nongovernmental organizations, and national administrations, among others in different countries of the region. Combined, these papers describe social processes, leadership, and institutional and organizational changes of relevance for stewardship of marine social-ecological systems in Latin America. The field of resilience research is still in an explorative phase in the region, and our ambition with this Special Feature is that the new discoveries presented may stimulate additional research in this field, including increased international cooperation with LAC scientists.

  11. A Carbon-Neutral California: Social Ecology and Prospects for 2050 GHG Reduction

    Stephen M. Wheeler

    2017-10-01

    Full Text Available How might a large jurisdiction approach carbon neutrality by 2050, and what initiatives might increase the chances of success? This article explores these questions using California as a case study. Current trends as well as multiple modeling studies show that existing policy directions for the state will not be sufficient. Additional initiatives appear needed to accelerate adoption of electric vehicles, reduce driving, reach 100 percent renewable electricity, convert existing buildings to zero-net-carbon status, change diet, and reduce consumption. The state’s social ecology does not currently support such changes. Consequently, planners and other professionals need to consider strategic actions to change social ecology as well as climate policy. Potential steps to do this include raising the price of carbon; revising the state’s tax system so as to increase public sector capacity; developing a stronger framework of incentives, mandates, and technical support between levels of government; and expanding educational and social marketing programs aimed at behavior change. A main implication of this analysis is that in many contexts worldwide sustainability planners should consider action on both policy and social ecology levels to maximize chances of success.

    Brazilian social protection programs have had consistent effects in reducing poverty and inequality among their respective target-groups: children, adolescents and pregnant and breastfeeding women. In 2011, the Brazil without Extreme Poverty program was launched as a strategy to eradicate extreme poverty by 2014. It makes the promotion of rights the core concept of the official political narrative. This study seeks to provide a systematic description of the Brazil without Extreme Poverty program and its initial results. A review of official documents and academic studies on the social protection programs was conducted. The Brazil without Extreme Poverty program represents an incremental approach to the social protection policies enacted by the previous administration. It advocates a multidimensional and focused approach, funded primarily by the federal government. The strategy subscribes to the international trend of associating social protection with employment and income generation policies.

    In this article, we examine the distribution of a marker of immune system stimulation-C-reactive protein-in urban Brazil. Social relationships are associated with immunostimulation, and we argue that cultural dimensions of social support, assessed by cultural consonance, are important in this process. Cultural consonance is the degree to which individuals, in their own beliefs and behaviors, approximate shared cultural models. A measure of cultural consonance in social support, based on a cultural consensus analysis regarding sources and patterns of social support in Brazil, was developed. In a survey of 258 persons, the association of cultural consonance in social support and C-reactive protein was examined, controlling for age, sex, body mass index, low-density lipoprotein cholesterol, depressive symptoms, and a social network index. Lower cultural consonance in social support was associated with higher C-reactive protein. Implications of these results for future research are discussed. © 2016 by the American Anthropological Association.

    Full Text Available This study reports the effects of a field trip environmental education program with a social-ecological perspective on the experience and learning of university students from China, Japan, South Korea and Vietnam. The students visited Jeju Island, the Saemangeum Sea Dike, the Demilitarized Zone and Seoul, South Korea. Their experiences and learning about social-ecological interactions were analyzed using the new environmental paradigm test, an evaluation questionnaire, group presentations and individual reports. Across demographic characteristics, the participants believed the program fairly presented the concept of social-ecological systems. Some developed new ideas of social-ecological systems through interpreting, transforming and contextualizing their field trip experience based on prior knowledge bases; others compared the sites to case studies. They preferred the sites where social-ecological issues were clearly presented by well-preserved landscapes, successful environmental management or environmental conflict. The results show the need for an advanced multi-dimensional methodology to evaluate students’ learning through constructive processes. The program design of this study from planning to field trip and evaluation, the field site design in which regional site resources were organized in a social-ecological context and the analysis of participants’ learning and experiences could contribute to attempts to couple the social-ecological perspective with the practice of sustainability and environmental education in field trip design.

    Studies analyzing motivation factors that lead to blood donation have found altruism to be the primary motivation factor; however, social capital has not been analyzed in this context. Our study examines the association between motivation factors (altruism, self-interest, and response to direct appeal) and social capital (cognitive and structural) across three large blood centers in Brazil. We conducted a cross-sectional survey of 7635 donor candidates from October 15 through November 20, 2009. Participants completed self-administered questionnaires on demographics, previous blood donation, human immunodeficiency virus testing and knowledge, social capital, and donor motivations. Enrollment was determined before the donor screening process. Among participants, 43.5 and 41.7% expressed high levels of altruism and response to direct appeal, respectively, while only 26.9% expressed high levels of self-interest. More high self-interest was observed at Hemope-Recife (41.7%). Of participants, 37.4% expressed high levels of cognitive social capital while 19.2% expressed high levels of structural social capital. More high cognitive and structural social capital was observed at Hemope-Recife (47.3 and 21.3%, respectively). High cognitive social capital was associated with high levels of altruism, self-interest, and response to direct appeal. Philanthropic and high social altruism were associated with high levels of altruism and response to direct appeal. Cognitive and structural social capital and social altruism are associated with altruism and response to direct appeal, while only cognitive social capital is associated with self-interest. Designing marketing campaigns with these aspects in mind may help blood banks attract potential blood donors more efficiently. © 2012 American Association of Blood Banks.

    The recent and projected increases in climate variability and the frequency of climate extremes are posing a profound challenge to society and the biosphere (IPCC 2012, IPCC 2013). Climate extremes can affect natural and managed ecosystems more severely than gradual warming. The ability of ecosystems to resist and recover from climate extremes is therefore of fundamental importance for society, which strongly relies on their ability to supply provisioning, regulating, supporting and cultural services. Society in turn triggers land-use and management decisions that affect ecosystem properties. Thus, ecological and socio-economic conditions are tightly coupled in what has been referred to as the social-ecological system. For ensuring human well-being in the light of climate extremes it is crucial to enhance the resilience of the social-ecological system (SES) across spatial, temporal and institutional scales. Stakeholders, such as resource managers, urban, landscape and conservation planners, decision-makers in agriculture and forestry, as well as natural hazards managers, require an improved knowledge base for better-informed decision making. To date the vulnerability and adaptive capacity of SESs to climate extremes is not well understood and large uncertainties exist as to the legacies of climate extremes on ecosystems and on related societal structures and processes. Moreover, we lack empirical evidence and incorporation of simulated future ecosystem and societal responses to support pro-active management and enhance social-ecological resilience. In our presentation, we outline the major research gaps and challenges to be addressed for understanding and enhancing the adaptive capacity of SES to absorb and adapt to climate extremes, including acquisition and elaboration of long-term monitoring data and improvement of ecological models to better project climate extreme effects and provide model uncertainties. We highlight scientific challenges and discuss

    2016-09-01

    Full Text Available A rise in qualitative social science manuscripts published in ecology and conservation journals speaks to the growing awareness of the importance of the human dimension in maintaining and improving Earth's ecosystems. Given the rise in the quantity of qualitative social science research published in ecology and conservation journals, it is worthwhile quantifying the extent to which this research is meeting established criteria for research design, conduct, and interpretation. Through a comprehensive review of this literature, we aimed to gather and assess data on the nature and extent of information presented on research design published qualitative research articles, which could be used to judge research quality. Our review was based on 146 studies from across nine ecology and conservation journals. We reviewed and summarized elements of quality that could be used by reviewers and readers to evaluate qualitative research (dependability, credibility, confirmability, and transferability; assessed the prevalence of these elements in research published in ecology and conservation journals; and explored the implications of sound qualitative research reporting for applying research findings. We found that dependability and credibility were reasonably well reported, albeit poorly evolved in relation to critical aspects of qualitative social science such as methodology and triangulation, including reflexivity. Confirmability was, on average, inadequately accounted for, particularly with respect to researchers' ontology, epistemology, or philosophical perspective and their choice of methodology. Transferability was often poorly developed in terms of triangulation methods and the suitability of the sample for answering the research question/s. Based on these findings, we provide a guideline that may be used to evaluate qualitative research presented in ecology and conservation journals to help secure the role of qualitative research and its application

    Daiane Borges Machado

    Full Text Available PURPOSE: To analyze whether income inequality and other social determinants are associated with suicide rate in Brazil. METHOD: This study used panel data from all 5,507 Brazilian municipalities from 2000 to 2011. Suicide rates were calculated by sex and standardized by age for each municipality and year. The independent variables of the regression model included the Gini Index, per capita income, percentage of individuals with up to eight years of education, urbanization, average number of residents per household, percentage of divorced people, of Catholics, Pentecostals, and Evangelicals. A multivariable negative binomial regression for panel data with fixed-effects specification was performed. RESULTS: The Gini index was positively associated with suicide rates; the rate ratio (RR was 1.055 (95% CI: 1.011-1.101. Of the other social determinants, income had a significant negative association with suicide rates (RR: 0.968, 95% CI: 0.948-0.988, whereas a low-level education had a positive association (RR: 1.015, 95% CI: 1.010-1.021. CONCLUSIONS: Income inequality represents a community-level risk factor for suicide rates in Brazil. The decrease in income inequality, increase in income per capita, and decrease in the percentage of individuals who did not complete basic studies may have counteracted the increase in suicides in the last decade. Other changes, such as the decrease in the mean residents per household, may have contributed to their increase. Therefore, the implementation of social policies that may improve the population's socioeconomic conditions and reduce income inequality in Brazil, and in other low and middle-income countries, can help to reduce suicide rates.

    To analyze whether income inequality and other social determinants are associated with suicide rate in Brazil. This study used panel data from all 5,507 Brazilian municipalities from 2000 to 2011. Suicide rates were calculated by sex and standardized by age for each municipality and year. The independent variables of the regression model included the Gini Index, per capita income, percentage of individuals with up to eight years of education, urbanization, average number of residents per household, percentage of divorced people, of Catholics, Pentecostals, and Evangelicals. A multivariable negative binomial regression for panel data with fixed-effects specification was performed. The Gini index was positively associated with suicide rates; the rate ratio (RR) was 1.055 (95% CI: 1.011-1.101). Of the other social determinants, income had a significant negative association with suicide rates (RR: 0.968, 95% CI: 0.948-0.988), whereas a low-level education had a positive association (RR: 1.015, 95% CI: 1.010-1.021). Income inequality represents a community-level risk factor for suicide rates in Brazil. The decrease in income inequality, increase in income per capita, and decrease in the percentage of individuals who did not complete basic studies may have counteracted the increase in suicides in the last decade. Other changes, such as the decrease in the mean residents per household, may have contributed to their increase. Therefore, the implementation of social policies that may improve the population's socioeconomic conditions and reduce income inequality in Brazil, and in other low and middle-income countries, can help to reduce suicide rates.

    Compared to malaria, tuberculosis and HIV/AIDS, schistosomiasis remains a truly neglected tropical disease. Schistosomiasis, perhaps more than any other disease, is entrenched in prevailing social-ecological systems, since transmission is governed by human behaviour (e.g. open defecation and patterns of unprotected surface water contacts) and ecological features (e.g. living in close proximity to suitable freshwater bodies in which intermediate host snails proliferate). Moreover, schistosomiasis is intimately linked with poverty and the disease has spread to previously non-endemic areas as a result of demographic, ecological and engineering transformations. Importantly though, thanks to increased advocacy there is growing awareness, financial and technical support to control and eventually eliminate schistosomiasis as a public health problem at local, regional and global scales. The purpose of this review is to highlight recent progress made in innovation, validation and application of new tools and strategies for research and integrated control of schistosomiasis. First, we explain that schistosomiasis is deeply embedded in social-ecological systems and explore linkages with poverty. We then summarize and challenge global statistics, risk maps and burden estimates of human schistosomiasis. Discovery and development research pertaining to novel diagnostics and drugs forms the centrepiece of our review. We discuss unresolved issues and emerging opportunities for integrated and sustainable control of schistosomiasis and conclude with a series of research needs. Copyright © 2010 Elsevier B.V.

  3. Social medicine, feminism and the politics of population: From transnational knowledge networks to national social movements in Brazil and Mexico.

    de la Dehesa, Rafael

    2018-02-28

    This article examines the role of national actors articulated with an explicitly counter-hegemonic transnational knowledge network (TKN) mobilising around social medicine in policy debates on population control and family planning. It focuses primarily on Brazil, using Mexico as a shadow case to highlight salient points of contrast. In doing so, it makes two contributions to larger debates about TKNs. First, it highlights the plural and contested nature of the knowledge production they enact, underscoring contestation around a global reproductive regime that consolidated around family planning. Second, it underscores how the position and relative influence of actors articulated with TKNs is shaped by political and institutional contexts at the national level, producing variable opportunities for the mobilisation of applied knowledge. Reflecting its advocates' embeddedness in larger opposition movements to authoritarian states, social medicine had a greater influence on these debates in Brazil, where synergies with a resurgent feminist movement reinforced a shared insistence on comprehensive women's healthcare and increased the salience of sterilisation abuse on the political agenda.

  4. Ecological and Social Dimensions of Ecosystem Restoration in the Nordic Countries

    2013-12-01

    Full Text Available An international overview of the extent and type of ecological restoration can offer new perspectives for understanding, planning, and implementation. The Nordic countries, with a great range of natural conditions but historically similar social and political structures, provide an opportunity to compare restoration approaches and efforts across borders. The aim of this study was to explore variation in ecological restoration using the Nordic countries as an example. We used recent national assessments and expert evaluations of ecological restoration. Restoration efforts differed among countries: forest and peatland restoration was most common in Finland, freshwater restoration was most common in Sweden, restoration of natural heathlands and grasslands was most common in Iceland, restoration of natural and semi-cultural heathlands was most common in Norway, and restoration of cultural ecosystems, mainly abandoned agricultural land, was most common in Denmark. Ecological restoration currently does not occur on the Faroe Islands. Economic incentives influence ecological restoration and depend on laws and policies in each country. Our analyses suggest that habitat types determine the methods of ecological restoration, whereas socio-economic drivers are more important for the decisions concerning the timing and location of restoration. To improve the understanding, planning, and implementation of ecological restoration, we advocate increased cooperation and knowledge sharing across disciplines and among countries, both in the Nordic countries and internationally. An obvious advantage of such cooperation is that a wider range of experiences from different habitats and different socio-economic conditions becomes available and thus provides a more solid basis for developing practical solutions for restoration methods and policies.

  5. Lack of ecological context can create the illusion of social success in Dictyostelium discoideum

    2016-01-01

    Studies of cooperation in microbes often focus on one fitness component, with little information about or attention to the ecological context, and this can lead to paradoxical results. The life cycle of the social amoeba Dictyostelium discoideum includes a multicellular stage in which not necessarily clonal amoebae aggregate upon starvation to form a possibly chimeric (genetically heterogeneous) fruiting body made of dead stalk and spores. The lab-measured reproductive skew in the spores of chimeras indicates strong social antagonism; this should result in low genotypic diversity, which is inconsistent with observations from nature. Two studies have suggested that this inconsistency stems from the one-dimensional assessment of fitness (spore production) and that the solution lies in tradeoffs between multiple traits, e.g.: spore size versus viability; and staying vegetative versus becoming dormant. We theoretically explore different tradeoff-implementing mechanisms and provide a unifying ecological framework ...

    Complexity thinking is increasingly being embraced by a wide range of academics and professionals as imperative for dealing with today's pressing social-ecological challenges. In this context, action researchers partner directly with stakeholders (communities, governance institutions, and work resource managers, etc.) to embed a complexity frame of reference for decision making. In doing so, both researchers and stakeholders must strive to internalize not only "intellectual complexity" (knowi...

  8. Governance and the Capacity to Manage Resilience in Regional Social-Ecological Systems

    Directory of Open Access Journals (Sweden)

    2006-06-01

    Full Text Available The sustainability of regional development can be usefully explored through several different lenses. In situations in which uncertainties and change are key features of the ecological landscape and social organization, critical factors for sustainability are resilience, the capacity to cope and adapt, and the conservation of sources of innovation and renewal. However, interventions in social-ecological systems with the aim of altering resilience immediately confront issues of governance. Who decides what should be made resilient to what? For whom is resilience to be managed, and for what purpose? In this paper we draw on the insights from a diverse set of case studies from around the world in which members of the Resilience Alliance have observed or engaged with sustainability problems at regional scales. Our central question is: How do certain attributes of governance function in society to enhance the capacity to manage resilience? Three specific propositions were explored: (1 participation builds trust, and deliberation leads to the shared understanding needed to mobilize and self-organize; (2 polycentric and multilayered institutions improve the fit between knowledge, action, and social-ecological contexts in ways that allow societies to respond more adaptively at appropriate levels; and (3 accountable authorities that also pursue just distributions of benefits and involuntary risks enhance the adaptive capacity of vulnerable groups and society as a whole. Some support was found for parts of all three propositions. In exploring the sustainability of regional social-ecological systems, we are usually faced with a set of ecosystem goods and services that interact with a collection of users with different technologies, interests, and levels of power. In this situation in our roles as analysts, facilitators, change agents, or stakeholders, we not only need to ask: The resilience of what, to what? We must also ask: For whom?

    1. In this study, we compared a conventional broiler production system keeping fast growing broilers with an organic broiler production system keeping slow growing broilers in the Netherlands, both managed by one person working a full time year (Full Time Equivalent, FTE). This comparison was based on a quantification of economic, ecological and social indicators. Indicators were quantified using scientific literature and national data sets. 2. The organic system performed better for the economic indicator net farm income per FTE than the conventional system. 3. Regarding ecological indicators, calculations showed a higher on-farm emission of ammonia per kg live weight for the organic system. Moreover, an organic system includes a higher risk for eutrophication per ha due to outdoor access. Emission of green house gasses, use of fossil fuels and use of land required for the production of one kg of live weight is higher for an organic than for a conventional system. This is mainly due to a lower feed conversion in organic production and use of organic feed. 4. The organic system performed better than the conventional system for the social indicators related to animal welfare time spent on walking, footpad lesions, mortality, and sound legs. Regarding the social indicator food safety was found that meat from an organic system contained less antibiotic residues and Salmonella contaminations but more Campylobacter contaminations than meat from a conventional system. 5. Changing from a conventional to an organic broiler production system, therefore, not only affects animal welfare, but also affects economic, ecological and other social issues. In this study, we ran into the situation that some information needed was lacking in literature and quantifications had to be based upon several sources. Therefore, an integrated on-farm assessment is needed, which can be used to develop a broiler production system that is economically profitable, ecologically sound, and

    Full Text Available Policies and actions that come from higher scale structures, such as international bodies and national governments, are not always compatible with the realities and perspectives of smaller scale units including indigenous communities. Yet, it is at this local social-ecological scale that mechanisms and solutions for dealing with unpredictability and change can be increasingly seen emerging from across the world. Although there is a large body of knowledge specifying the conditions necessary to promote local governance of natural resources, there is a parallel need to develop practical methods for operationalizing the evaluation of local social-ecological systems. In this paper, we report on a systemic, participatory, and visual approach for engaging local communities in an exploration of their own social-ecological system. Working with indigenous communities of the North Rupununi, Guyana, this involved using participatory video and photography within a system viability framework to enable local participants to analyze their own situation by defining indicators of successful strategies that were meaningful to them. Participatory multicriteria analysis was then used to arrive at a short list of best practice strategies. We present six best practices and show how they are intimately linked through the themes of indigenous knowledge, local governance and values, and partnerships and networks. We highlight how developing shared narratives of community owned solutions can help communities to plan governance and management of land and resource systems, while reinforcing sustainable practices by discussing and showcasing them within communities, and by engendering a sense of pride in local solutions.

  15. A Social-Ecological Framework for Urban Stewardship Network Research to Promote Sustainable and Resilient Cities

    2016-09-01

    Full Text Available To realize more sustainable and resilient urban social-ecological systems, there is great need for active engagement from diverse public agencies, non-profit organizations, businesses, natural resource managers, scientists, and other actors. Cities present unique challenges and opportunities for sustainability and resilience, as issues and organizations are frequently intertwined in networks of relations. Understanding and leveraging the range of knowledge types, motivations, skills, and goals of diverse participants and their networks is fundamental to sustainable and resilient cities. As efforts to examine and understand urban stewardship networks continue to emerge, it is increasingly clear that there are no structured or systematic frameworks to guide the integration of social and ecological phenomena. Such a framework could facilitate planning new urban stewardship network research, and provide a basis for comparisons among cities and their urban stewardship networks. In this paper, we develop and present a social-ecological framework for examining and understanding urban stewardship networks. To illustrate this framework and provide examples of its prospective and evaluative utility, we use examples from the U.S. Forest Service’s Stewardship Mapping (STEW-MAP network in the United States from Baltimore, MD, USA, New York City, NY, USA, San Juan, Puerto Rico, USA, and Seattle, WA, USA.

    2014-06-01

    Full Text Available Biodiversity conservation continues to be a challenging task for societies worldwide. We undertook a resilience assessment to address the following question: What are the ramifications of social-ecological system dynamics for biodiversity governance of a nationally significant landscape? Resilience assessment offers promise for guiding response strategies, potentially enabling consideration of ecological, social, economic, and governance influences on biodiversity-related activities. Most resilience assessments have, however, struggled to effectively incorporate governance influences. We applied a modified version of the Resilience Alliance workbook approach to explicitly address governance influences at each stage of an assessment of internationally significant biodiversity features in protected areas of the Australian Alps. The vulnerability of the Alps system to climate change suggests that it is moving into a release stage, with subsequent transformation hypothesized. Network governance is argued as enabling flexible, adaptive management and comprehensive engagement of stakeholders, both of which are critical to shaping how this transformation of the Alps as a valued focal system will occur. The Australian Alps Liaison Committee provides a promising governance structure for collaboration and comanagement across multiple jurisdictions. Our contribution was to demonstrate how a resilience assessment that explicitly embeds governance influences in social-ecological system dynamics can point to pathways for governance reform in the context of system transformation.

  17. Social Interface Model: Theorizing Ecological Post-Delivery Processes for Intervention Effects.

    2018-01-03

    Successful prevention programs depend on a complex interplay among aspects of the intervention, the participant, the specific intervention setting, and the broader set of contexts with which a participant interacts. There is a need to theorize what happens as participants bring intervention ideas and behaviors into other life-contexts, and theory has not yet specified how social interactions about interventions may influence outcomes. To address this gap, we use an ecological perspective to develop the social interface model. This paper presents the key components of the model and its potential to aid the design and implementation of prevention interventions. The model is predicated on the idea that intervention message effectiveness depends not only on message aspects but also on the participants' adoption and adaptation of the message vis-à-vis their social ecology. The model depicts processes by which intervention messages are received and enacted by participants through social processes occurring within and between relevant microsystems. Mesosystem interfaces (negligible interface, transference, co-dependence, and interdependence) can facilitate or detract from intervention effects. The social interface model advances prevention science by theorizing that practitioners can create better quality interventions by planning for what occurs after interventions are delivered.

    2001-10-01

    For most smokers, tobacco dependence begins in childhood or adolescence. This review summarizes the state of social science with respect to the prevention of tobacco use. Social ecology is introduced as a theoretical framework useful for organizing prevention approaches. In recent years, the field has shifted from approaches directed at individuals, towards appreciation of additional, more comprehensive social and environmental influences on initiation. These range from intra-individual factors (including physiological responses to nicotine and the psychology of use) to individual, interpersonal, organizational, community, and population factors affecting access and demand. This review highlights prevention approaches that address social and societal influences, from school programs that attempt to change susceptibility of individual youth to tobacco, to community projects, media campaigns, restrictive policies, and tobacco pricing. The most promising approaches are those designed with input based on extensive formative research including studies with youth, directed at multiple levels of the social ecology, and sustained over time with significant resources and ongoing, multi-sector inputs.

    2013-12-01

    Social network analysis (SNA) is a framework used to study the structure of societies. As an umbrella term that encompasses various tools of graph theory and mathematical models to visualize networks, SNA allows researchers to detect and quantify patterns in social networks. Within SNA, individuals are not independent, but are symbiotic or linked with one another in a network. Given its powerful analytical tools, SNA is capable of addressing a range of animal behaviors, and has accordingly become increasingly popular in behavioral ecology studies examining such notions as mate choice/sexual selection, cooperation, information flow and disease transition, behavioral strategies of individuals, fitness consequences of sociality and network stability. Nevertheless, SNA it relatively underutilized among Chinese behavioral ecologists. This study aims at highlighting the benefits of SNA in studying animal behaviors in order to promote greater utilization of SNA within Chinese studies. By first introducing social network theory and demonstrating how social networks can influence individual and collective behaviors, this paper provide a prospective overview of SNA's general utilization for the study of animal behavioral ecology as well as promising directions in the overall use of SNA.

    Information on the knowledge, uses, and abundance of natural resources in local communities can provide insight on conservation status and conservation strategies in these locations. The aim of this research was to evaluate the uses, knowledge and conservation status of plants in two Quilombolas (descendants of slaves of African origin) communities in the Atlantic rainforest of Brazil, São Sebastião da Boa Vista (SSBV) and São Bento (SB). We used a combination of ethnobotanical and ecological survey methods to ask: 1) What ethnobotanical knowledge do the communities hold? 2) What native species are most valuable to them? 3) What is the conservation status of the native species used? Thirteen local experts described the names and uses of 212 species in SSBV (105 native species) and 221 in SB (96 native species). Shannon Wiener diversity and Pielou’s Equitability indices of ethnobotanical knowledge of species were very high (5.27/0.96 and 5.28/0.96, respectively). Species with the highest cultural significance and use-value indexes in SSBV were Dalbergia hortensis (26/2.14), Eremanthus erythropappus (6.88/1), and Tibouchina granulosa (6.02/1); while Piptadenia gonoacantha (3.32/1), Sparattosperma leucanthum (3.32/1) and Cecropia glaziovii (3.32/0.67) were the highest in SB. Thirty-three native species ranked in the highest conservation priority category at SSBV and 31 at SB. D. hortensis was noteworthy because of its extremely high cultural importance at SSBV, and its categorization as a conservation priority in both communities. This information can be used towards generating sustainable use and conservation plans that are appropriate for the local communities. PMID:29182637

  1. The "social" aspect of social-ecological systems: a critique of analytical frameworks and findings from a multisite study of coastal sustainability

    Tim Stojanovic

    2016-09-01

    Full Text Available We evaluate whether society can adequately be conceptualized as a component of social-ecological systems, given social theory and the current outputs of systems-based research. A mounting critique from the social sciences posits that resilience theory has undertheorized social entities with the concept of social-ecological systems. We trace the way that use of the term has evolved, relating to social science theory. Scientometic and network analysis provide a wide range of empirical data about the origin, growth, and use of this term in academic literature. A content analysis of papers in Ecology and Society demonstrates a marked emphasis in research on institutions, economic incentives, land use, population, social networks, and social learning. These findings are supported by a review of systems science in 18 coastal assessments. This reveals that a systems-based conceptualization tends to limit the kinds of social science research favoring quantitative couplings of social and ecological components and downplaying interpretive traditions of social research. However, the concept of social-ecological systems remains relevant because of the central insights concerning the dynamic coupling between humans and the environment, and its salient critique about the need for multidisciplinary approaches to solve real world problems, drawing on heuristic devices. The findings of this study should lead to more circumspection about whether a systems approach warrants such claims to comprehensiveness. Further methodological advances are required for interdisciplinarity. Yet there is evidence that systems approaches remain highly productive and useful for considering certain social components such as land use and hybrid ecological networks. We clarify advantages and restrictions of utilizing such a concept, and propose a reformulation that supports engagement with wider traditions of research in the social sciences.

    Full Text Available The recognition and fulfilment of the sexual and reproductive health and rights (SRHR of all individuals and couples affected by HIV, including HIV-serodiscordant couples, requires intervention strategies aimed at achieving safe and healthy pregnancies and preventing undesired pregnancies. Reducing risk of horizontal and vertical transmission and addressing HIV-related infertility are key components of such interventions. In this commentary, we present challenges and opportunities for achieving safe pregnancies for serodiscordant couples through a social ecological lens. At the individual level, knowledge (e.g. of HIV status, assisted reproductive technologies and skills (e.g. adhering to antiretroviral therapy or pre-exposure prophylaxis are important. At the couple level, communication between partners around HIV status disclosure, fertility desires and safer pregnancy is required. Within the structural domain, social norms, stigma and discrimination from families, community and social networks influence individual and couple experiences. The availability and quality of safer conception and fertility support services within the healthcare system remains essential, including training for healthcare providers and strengthening integration of SRHR and HIV services. Policies, legislation and funding can improve access to SRHR services. A social ecological framework allows us to examine interactions between levels and how interventions at multiple levels can better support HIV-serodiscordant couples to achieve safe pregnancies. Strategies to achieve safer pregnancies should consider interrelated challenges at different levels of a social ecological framework. Interventions across multiple levels, implemented concurrently, have the potential to maximize impact and ensure the full SRHR of HIV-serodiscordant couples.

    2008-04-01

    Full Text Available Abstract Background The literature is scarce on the social and geographic inequalities in the access to and implementation of the fluoridation of public water supplies. This study adds knowledge to the Brazilian experience of the chronic privation of water and wastewater policies, access to potable water and fluoridation in the country. Thus, the aim of this study was to verify possible inequalities in the population's access to fluoridated drinking water in 246 Brazilian municipalities. Methods The information on the process of water fluoridation in the municipalities and in the macro region in which each municipality is located was obtained from the national epidemiological survey which was concluded in 2003. The data relating to the human development index at municipal level (HDI-M and access to mains water came from the Brazilian Human Development Atlas, whilst the size of the population was obtained from a governmental source. The Fisher exact test (P Results The results clearly showed that there is a relationship between municipalities with larger populations, located in more socio-economically advantaged regions and with better HDI-M, and where fluoridation is both present and has been implemented for a longer period of time (started before 1990. Conclusion The findings suggest that the aim of treating water with fluoride may not be being adequately achieved, requiring more effective strategies so that access to this measure can be expanded equitably.

    Could HIV/AIDS become a positive factor for a child's life? This contradiction is explored in this paper based on anthropological fieldwork and research in Brazil. I used participant observation and informal interviewing both with children living with HIV/AIDS and uninfected street children to obtain qualitative data. Brazil is known as a country leader in social responses towards the AIDS epidemic. Not only has access to antiretroviral medications been assured, but also a series of help networks guarantee that the human rights of HIV-infected people be respected. Children and adolescents benefit equally from these social gains. As such, many children born to HIV-positive women have reached adolescence and have 'normal' lives. This article explores the life experiences of children and adolescents infected by HIV and compares them to the life experiences of street children. Even though the AIDS epidemic is linked to death, infected children and adolescents dream about their lives and futures. Contradictorily, street children, who have not acquired the virus and are considered healthy from a biological stand point, have no prospective plans and answer without hope to questions about the future.

  6. URBANIZATION, ACCOUNTABILITY AND SOCIAL INCLUSION IN A COMPARATIVE PERSPECTIVE: BRAZIL VS. CHINA

    Full Text Available This paper aims to analyze the context in which occurred the intense urbanization in China over the past 30 years, by comparing the different strategies applied by Brazil and China with respect to the urban development aimed at improving the Quality of Life, Urban Planning, Social Inclusion, Public Participation and Environmental Protection in the cities. In this process, we analyzed the legal basis and strategies for urban expansion considering their proposals to support the productive activity and the structure of economic development. The selection of the two countries was motivated by FIA’s course extension to China, which allowed us to observe intense contrasts of the housing policies for the inclusion of migrants due to the industrialization process of the two developing nations. The comparative analysis was proven to be valid because, despite being strikingly different in several aspects, these two countries have similar challenges, since both of them deal with the enormous challenge of including historically marginalized populations within the social context. Thus, this paper proposes to discuss the question of why Brazil, with an income per capita many times larger than China, has not been able to overtake this country with respect to the inclusion of its most poor population within the realm of dignified housing, and therefore, include this group within the market practices. Keywords: Urbanization, China, Urban Development, Accountability, Cities, Immigration, Urban Reform.

    In Brazil, isolation of individuals affected with leprosy was compulsory by law from 1920 to 1962, but in reality, confinement of patients to leprosaria continued until the 1980s. The social participation restriction of people still living in these institutions has never been investigated systematically. To examine the extent and type of participation restriction perceived by former leprosy patients living in the Centro de Convivência Antônio Diogo (CCAD), a previous leprosy colony in rural Northeast Brazil, by using the Participation Scale. Forty (51-9%) out of 77 individuals reported significant participation restrictions, mainly related to work and mobility. Perceived participation restriction was significantly higher in people living in nursing units of the CCAD (P = 0-001), if diagnosis of leprosy was made before 1982 (P = 0.002), in the presence of walking limitation (P Social rehabilitation, especially in the areas of work and mobility, is strongly needed together with prevention of debilitating physical sequelae and reduction of stigmatisation.

    Although most studies consider health to be the result of social and economic insertion of the individuals, health may be considered a determining factor of the social opportunities achieved, especially with respect to chances of social mobility. The scope of this article is to understand the magnitude of the concurrent associations that sociodemographic, health and quality of life conditions (SF-36) exercise on chances of intergenerational social mobility on a probability sample of Brazilian homes in 2008. Social mobility was determined by the transition between occupational groups, which were defined using the Ganzeboom scale. Sociodemographic, health and quality of life features were associated with upward social mobility through logistic regression. A high level of schooling was the main determinant of chances of intergenerational social mobility. Women and youngsters ascended more intergenerationally. A positive association was observed between self assessment of health, physical health scores and upward mobility. Social mobility has become established as a multideterminate event. Physical health and perceived health were capable of influencing social transitions.

    Full Text Available A sample (n=124 of schizophrenic patients from a defined catchment area of the city os S.Paulo, Brazil, who had been consecutively admitted to hospital, was assessed for psychopathological status and social adjustment levels. Sociodemographic, socio-economic and occupational characteristics were recorded: almost 30% of the subjects had no occupation and received no social benefit, more than two-thirds had a monthly per capita income of US$ 100.00 or less. Sixty-five percent presented with Schneiderian firstrank symptoms. Nearly half the sample showed poor or very poor social adjustment in the month prior to admission. The most affected areas of social functioning were participation in the household activities, work and social withdrawal. The current mental health policy of promoting extra-mural care as an alternative to the previous hospital-based model will then mean the investment in a network of new community-based services, that give effective treatment and support to patients and their families. The need of further research into the current picture of mental disorders in the country is stressed.

    To study patterns of alcohol consumption and prevalence of high-risk drinking. A household survey was carried out in a sample of 2,302 adults in Salvador, Brazil. Cases of High-Risk Drinking (HRD) were defined as those subjects who referred daily or weekly binge drinking plus episodes of drunkenness and those who reported any use of alcoholic beverages but with frequent drunkenness (at least once a week). Fifty-six per cent of the sample acknowledged drinking alcoholic beverages. Overall consumption was significantly related with gender (male), marital status (single), migration (non-migrant), better educated (college level), and social class (upper). No significant differences were found regarding ethnicity, except for cachaça (Brazilian sugarcane liquor) and other distilled beverages. Overall 12-month prevalence of high-risk drinking was 7%, six times more prevalent among males than females (almost 13% compared to 2.4%). A positive association of HRD prevalence with education and social class was found. No overall relationship was found between ethnicity and HRD. Male gender and higher socioeconomic status were associated with increased odds of HRD. Two-way stratified analyses yielded consistent gender effects throughout all strata of independent variables. The findings suggest that social and cultural elements determine local patterns of alcohol-drinking behavior. Additional research on long-term and differential effects of gender, ethnicity, and social class on alcohol use and misuse is needed in order to explain their role as sources of social health inequities.

    Human factors, including contact structure, movement, impact on the environment and patterns of behaviour, can have significant influence on the emergence of novel infectious diseases and the transmission and amplification of established ones. As anthropogenic climate change alters natural systems and global economic forces drive land-use and land-cover change, it becomes increasingly important to understand both the ecological and social factors that impact infectious disease outcomes for human populations. While the field of disease ecology explicitly studies the ecological aspects of infectious disease transmission, the effects of the social context on zoonotic pathogen spillover and subsequent human-to-human transmission are comparatively neglected in the literature. The social sciences encompass a variety of disciplines and frameworks for understanding infectious diseases; however, here we focus on four primary areas of social systems that quantitatively and qualitatively contribute to infectious diseases as social-ecological systems. These areas are social mixing and structure, space and mobility, geography and environmental impact, and behaviour and behaviour change. Incorporation of these social factors requires empirical studies for parametrization, phenomena characterization and integrated theoretical modelling of social-ecological interactions. The social-ecological system that dictates infectious disease dynamics is a complex system rich in interacting variables with dynamically significant heterogeneous properties. Future discussions about infectious disease spillover and transmission in human populations need to address the social context that affects particular disease systems by identifying and measuring qualitatively important drivers.This article is part of the themed issue 'Opening the black box: re-examining the ecology and evolution of parasite transmission'. © 2017 The Author(s).

    Balancing ecological and social outcomes of conservation actions is recognized in global conservation policy but is challenging in practice. Compensation to land owners or users for foregone assets has been proposed by economists as an efficient way to mitigate negative social impacts of human displacement from protected areas. Joint empirical assessments of the conservation and social impacts of protected area establishment involving compensation payments are scarce. We synthesized social and biological studies related to the establishment of the Derema forest corridor in Tanzania's biodiverse East Usambara Mountains. This lengthy conservation process involved the appropriation of approximately 960 ha of native canopy agroforest and steep slopes for the corridor and monetary compensation to more than 1100 claimants in the surrounding villages. The overarching goals from the outset were to conserve ecological processes while doing no harm to the local communities. We evaluated whether these goals were achieved by analyzing 3 indicators of success: enhancement of forest connectivity, improvement of forest condition, and mitigation of negative impacts on local people's livelihoods. Indicators of forest connectivity and conditions were enhanced through reductions of forest loss and exotic species and increases in native species and canopy closure. Despite great efforts by national and international organizations, the intervention failed to mitigate livelihood losses especially among the poorest people. The Derema case illustrates the challenges of designing and implementing compensation schemes for conservation-related displacement of people. © 2014 Society for Conservation Biology.

  16. Development and evolution of brain allometry in wasps (Vespidae): size, ecology and sociality.

    2017-08-01

    We review research on brain development and brain evolution in the wasp family Vespidae. Basic vespid neuroanatomy and some aspects of functional neural circuitry are well-characterized, and genomic tools for exploring brain plasticity are being developed. Although relatively modest in terms of species richness, the Vespidae include species spanning much of the known range of animal social complexity, from solitary nesters to highly eusocial species with some of the largest known colonies and multiple reproductives. Eusocial species differ in behavior and ecology including variation in queen/worker caste differentiation and in diurnal/nocturnal activity. Species differences in overall brain size are strongly associated with brain allometry; relative sizes of visual processing tissues increase at faster rates than antennal processing tissues. The lower relative size of the central-processing mushroom bodies (MB) in eusocial species compared to solitary relatives suggests sociality may relax demands on individual cognitive abilities. However, queens have greater relative MB volumes than their workers, and MB development is positively associated with social dominance status in some species. Fruitful areas for future investigations of adaptive brain investment in the clade include sampling of key overlooked taxa with diverse social structures, and the analysis of neural correlations with ecological divergence in foraging resources and diel activity patterns.

    2015-06-01

    Anthropology and global health have long been a focus of research for both biological and medical anthropologists. Research has looked at physiological adaptations to high altitudes, community responses to water-borne diseases, the integration of traditional and biomedical approaches to health, global responses to HIV/AIDS, and more recently, to the application of cultural approaches to the control of the Ebola epidemic. Academic anthropology has employed theory and methods to extend knowledge, but less often to apply that knowledge. However, anthropologists outside of the academy have tackled global health issues such as family planning and breast-feeding by bringing together applied medical anthropology and social marketing. In 2014, that potent and provocative combination resulted in the University of South Florida in Tampa, Florida being made the home of an innovative center designed to combine academic and applied anthropology with social marketing in order to facilitate social change. This article discusses how inter- and intra-disciplinary research/application has led to the development of Florida's first World Health Organization Collaborating Center (WHO CC), and the first such center to focus on social marketing, social change and non-communicable diseases. This article explains the genesis of the Center and presents readers with a brief overview, basic principles and applications of social marketing by reviewing a case study of a water conservation project. The article concludes with thoughts on the ecology of collaboration among global health, medical anthropology and social marketing practitioners.

    This article provides an ecological framework for understanding adolescent-initiated parent abuse. We review research on adolescent-initiated parent abuse, identifying sociodemographic characteristics of perpetrators and victims (e.g., gender, age, race/ethnicity, and socioeconomic status [SES]). Bronfenbrenner's [1] ecological systems theory is applied, which examines the risk and protective factors for adolescent-initiated parent abuse within micro- (maltreatment, domestic violence, parenting behavior and disciplinary strategies), meso- (peer influence), exo- (media influence), macro- (gender role socialization), and chronosystem (change in family structure) levels. Findings from our review suggest that older and White children are significantly more likely to abuse their parents. Females are selective in the target of their aggression, while males target family members in general. Mothers are significantly more likely to be abused than fathers. However, researchers also report variations in the association between SES and parent abuse. Domestic violence and child maltreatment are risk factors, while findings on parenting behavior and disciplinary strategies are mixed. Peer influence, exposure to media violence, gender role socialization, and change in family structure can potentially increase the risk of parent abuse. Practice and research implications are also discussed. An ecological systems framework allows for an examination of how various contexts interact and influence parent abuse behavior, and can provide needed directions for further research.

    Marine ecosystems provide many benefits to people, including food, protection from coastal storms, and places for recreation and spiritual renewal. These benefits are threatened by human impacts at multiple scales, including fisheries over-exploitation and global climatic change. More solutions-oriented knowledge of the connections between people and nature is urgently needed. I will discuss the approach my collaborators and I have developed to investigate the connections between people and marine ecosystems in the context of the small-scale fisheries of Mexico's Gulf of California. To illustrate the value of this coupled systems approach, I will present findings from two geographic scales. First, using a coupled bio-economic model based on several communities in the Mexican state of Baja California Sur (BCS), I will show how fishers' decisions are influenced by both climatic and institutional variation, and the consequences of these interactions for economic and ecological outcomes associated with fishing. Second, I will place these local-scale results in a broader context. Drawing on both natural and social science theory and data, I will show how environmental and institutional factors related to sustainability vary substantially throughout BCS. Fishing communities that exhibit greater potential for social-ecological sustainability in one dimension do not necessarily exhibit it in others. These results highlight the importance of integrative, coupled system analyses when implementing spatial planning and other ecosystem-based strategies and yield an understanding of the sustainability of coupled social-ecological systems that is quite distinct from that provided by either biophysical or social sciences alone.

    Contact networks, behavioral interactions, and shared use of space can all have important implications for the spread of disease in animals. Social networks enable the quantification of complex patterns of interactions; therefore, network analysis is becoming increasingly widespread in the study of infectious disease in animals, including wildlife. We present an introductory guide to using social-network-analytical approaches in wildlife disease ecology, epidemiology, and management. We focus on providing detailed practical guidance for the use of basic descriptive network measures by suggesting the research questions to which each technique is best suited and detailing the software available for each. We also discuss how using network approaches can be used beyond the study of social contacts and across a range of spatial and temporal scales. Finally, we integrate these approaches to examine how network analysis can be used to inform the implementation and monitoring of effective disease management strategies.

    Cooperation amongst resource users holds the key to overcoming the social dilemma that characterizes community-based common-pool resource management. But is cooperation alone enough to achieve sustainable resource use? The short answer is no. Developing management strategies in a complex social-ecological environment also requires ecological knowledge and approaches to deal with perceived environmental uncertainty. Recent behavioral experimental research indicates variation in the degree to which a group of users can identify a sustainable exploitation level. In this paper, we identify social-ecological micro-foundations that facilitate cooperative sustainable common-pool resource use. We do so by using an agent-based model (ABM) that is informed by behavioral common-pool resource experiments. In these experiments, groups that cooperate do not necessarily manage the resource sustainably, but also over- or underexploit. By reproducing the patterns of the behavioral experiments in a qualitative way, the ABM represents a social-ecological explanation for the experimental observations. We find that the ecological knowledge of each group member cannot sufficiently explain the relationship between cooperation and sustainable resource use. Instead, the development of a sustainable exploitation level depends on the distribution of ecological knowledge among the group members, their influence on each other's knowledge, and the environmental uncertainty the individuals perceive. The study provides insights about critical social-ecological micro-foundations underpinning collective action and sustainable resource management. These insights may inform policy-making, but also point to future research needs regarding the mechanisms of social learning, the development of shared management strategies and the interplay of social and ecological uncertainty.

    The metabolic syndrome (MS) is characterized by multiple cardiovascular risk factors such as central obesity, arterial hypertension, dyslipidemia and hyperinsulinemia and is associated with a higher incidence of cardiovascular events and mortality. The aim of the present work is to describe the prevalence of MS in an urban population from a highly admixed developing country and to characterize the different correlations between this diagnosis, cardiovascular risk factors and demographic variables distributed in this population. A cross-sectional study of risk factors for cardiovascular diseases was performed in the urban population of Vitoria, Brazil (n=1507). Major cardiovascular risk factors such as smoking habits, alcohol intake, amount of physical activity, diabetes and hypertension were inquired. Blood biochemical assays were performed by standard techniques in 12 h fasting blood sample and Metabolic Syndrome (MS) was characterizes following the ATP III criteria. The analysis of 1507 individuals showed a 25.43% general prevalence of MS without any significant difference between sexes, but a clear relation of the prevalence with progressing age (p=social economic class that was highly associated with the risk of MS in women as their social class was lower, but not in men. This cross-sectional study from a large urban population in Brazil showed a high general prevalence of MS (25.4%), which is increased as the population becomes older (especially in women) and poorer. Although prevalence was very similar in both genders, the frequency of components defining the syndrome varied greatly amongst them. In particular, a significant interaction between gender and social class was observed and may shed light in our understanding of the complex interplay between demographic and biological risk factors for metabolic syndrome.

    Full Text Available Social Psychology in Brazil has been showing a progressive scientific growth since the 1970's. Such development justifies the current interest in performing an evaluation of scientific contributions of Brazilian Social Psychologists within the international context. In this respect, a literature review allowed the identification of 10 evaluative models in Social Psychology. Such models are applied to the psychological and sociological currents in Social Psychology, which are the most prominent internationaly. Even though such evaluative models are well designed, they present limitations with regard to their spectrum of application within Social Psychology. Thus a 5 - dimensional conceptual model has been developed: Philosophical assumptions; Research subject; Research methods and techniques; Conceptual matrix; Applications. Main results of the literature review were obtained from this 5 - dimensional model.A Psicologia Social no Brasil vem apresentando uma crescente maturidade científica desde a década de 1970. Esse desenvolvimento justifica o atual interesse em proceder a uma avaliação das contribuições científicas de psicólogos sociais brasileiros numa perspectiva internacional. Nesse sentido, foi conduzido um estudo bibliográfico, que possibilitou a identificação de 10 modelos de avaliação da Psicologia Social. Esses modelos são aplicados às vertentes psicológica e sociológica da Psicologia Social, que são as que mais se destacam no plano internacional. Embora esses modelos avaliativos estejam tecnicamente bem fundamentados, apresentam limitações quanto à abrangência do objeto a avaliar, que é a Psicologia Social. Assim, propõe-se um modelo baseado em cinco dimensões: pressupostos filosóficos; objeto de investigação; métodos e técnicas de pesquisa; matriz conceitual; e, aplicações. Os principais resultados deste estudo bibliográfico foram obtidos mediante a aplicação do modelo dessas cinco dimensões básicas.

    Big data can be used to assess perceptions about public health issues. This study assessed social media data from Twitter to inform communication campaigns to promote HIV testing and reduce discrimination related to HIV/AIDS or towards key populations to the HIV epidemic, and its potential utility to evaluate such campaigns through HIV testing uptake. Tweets from Brazil were collected from January 2014 to March 2015 and filtered by four categories of keywords including discrimination, HIV prevention, HIV testing, and HIV campaigns. In total over 100,000 geo-located tweets were extracted and analyzed. A dynamic online dashboard updated daily allowed mapping trends, anomalies and influencers, and enabled its use for feedback to campaigns, including correcting misconceptions. These results encourage the use of social networking data for improved messaging in campaigns. Clinical HIV test data was collected monthly from the city of Curitiba and compared to the number of tweets mapped to the city showing a moderate positive correlation (r = 0.39). Results are limited due to the availability of the HIV testing data. The potential of social media as a proxy for HIV testing uptake needs further validation, which can only be done with higher frequency and higher spatial granularity of service delivery data, enabling comparisons with the social media data. Such timely information could empower early response immediate media messaging to support programmatic efforts, such as HIV prevention, testing, and treatment scale up.

    Full Text Available We examined how social-ecological factors in the land-change decision-making process influenced neighboring decisions and trajectories of alternative landscape ecologies. We decomposed individual landowner decisions to conserve or develop forests in the rapidly growing Charlotte, North Carolina, U.S. region, exposing and quantifying the effects of forest quality, and social and cultural dynamics. We tested the hypothesis that the intrinsic value of forest resources, e.g., cultural attachment to land, influence woodland owners' propensity to sell. Data were collected from a sample of urban, nonindustrial private forest (U-NIPF owners using an individualized survey design that spatially matched land-owner responses to the ecological and timber values of their forest stands. Cluster analysis (n = 126 revealed four woodland owner typologies with widely ranging views on the ecosystem, cultural, and historical values of their forests. Classification tree analysis revealed woodland owners' willingness to sell was characterized by nonlinear, interactive factors, including sense of place values regarding the retention of native vegetation, the size of forest holdings, their connectedness to nature, 'pressure' from surrounding development, and behavioral patterns, such as how often landowners visit their land. Several ecological values and economic factors were not found to figure in the decision to retain forests. Our study design is unique in that we address metropolitan forest persistence across urban-rural and population gradients using a unique individualized survey design that richly contextualizes survey responses. Understanding the interplay between policies and landowner behavior can also help resource managers to better manage and promote forest persistence. Given the region's paucity of policy tools to manage the type and amount of development, the mosaic of land cover the region currently enjoys is far from stable.

    In order to sustainably conserve biodiversity, many protected areas, particularly private protected areas, must find means of self-financing. Ecotourism is increasingly seen as a mechanism to achieve such financial sustainability. However, there is concern that ecotourism operations are driven to achieve successful game-viewing, influencing the management of charismatic species. An abundance of such species, including the African elephant (Loxodonta africana), has been stocked in protected areas under the assumption that they will increase ecotourism value. At moderate to high densities, the impact of elephants is costly; numerous studies have documented severe changes in biodiversity through the impacts of elephants. Protected areas that focus on maintaining high numbers of elephants may therefore face a conflict between socioeconomic demands and the capacity of ecological systems. We address this conflict by analyzing tourist elephant-sighting records from six private and one statutory protected area, the Addo Elephant National Park (AENP), in the Eastern Cape Province of South Africa, in relation to elephant numbers. We found no relationship between elephant density and elephant-viewing success. Even though elephant density in the AENP increased over time, a hierarchical partitioning analysis indicated that elephant density was not a driver of tourist numbers. In contrast, annual tourist numbers for the AENP were positively correlated with general tourist numbers recorded for South Africa. Our results indicate that the socioeconomic and ecological requirements of protected areas in terms of tourism and elephants, respectively, converge. Thus, high elephant densities and their associated ecological costs are not required to support ecotourism operations for financial sustainability. Understanding the social and ecological feedbacks that dominate the dynamics of protected areas, particularly within private protected areas, can help to elucidate the management

    Full Text Available We studied the structural habitat use and the thermal ecology of Gonatodes humeralis (Guichenot, 1855 in São Luís, Maranhão, Brazil, to examine intersexual differences in the use of perch features and to simultaneously analyze reciprocal differences on thermal ecology between the sexes. Gonatodes humeralis body temperature was strongly correlated with environmental temperatures (air and substrate, but air temperature had an additional effect on the males' body temperatures after removing the effect of the substrate temperature. Males and females differed significantly in perch height use above ground (males perched higher but the sexes did not differ in the trunk perimeter used. Gonatodes humeralis tended to use the larger tree trunks available in its environment and selected trunks with deeper leaf litter at the base. It is hypothesized that choosing tree trunks with deeper leaf litter is a defensive behavior against predation.

  12. Understanding the psychology of bullying: Moving toward a social-ecological diathesis-stress model.

    Swearer, Susan M; Hymel, Shelley

    2015-01-01

    With growing recognition that bullying is a complex phenomenon, influenced by multiple factors, research findings to date have been understood within a social-ecological framework. Consistent with this model, we review research on the known correlates and contributing factors in bullying/victimization within the individual, family, peer group, school and community. Recognizing the fluid and dynamic nature of involvement in bullying, we then expand on this model and consider research on the consequences of bullying involvement, as either victim or bully or both, and propose a social-ecological, diathesis-stress model for understanding the bullying dynamic and its impact. Specifically, we frame involvement in bullying as a stressful life event for both children who bully and those who are victimized, serving as a catalyst for a diathesis-stress connection between bullying, victimization, and psychosocial difficulties. Against this backdrop, we suggest that effective bullying prevention and intervention efforts must take into account the complexities of the human experience, addressing both individual characteristics and history of involvement in bullying, risk and protective factors, and the contexts in which bullying occurs, in order to promote healthier social relationships.

    This second of two articles describes the application of disaster mental health interventions within the context of the child’s social ecology consisting of (he Micro-, Meso-, Exo-, and Macrosystems. Microsystem interventions involving parents, siblings, and close friends include family preparedness planning and practice, psychoeducation, role modeling, emotional support, and redirection. Mesosystem interventions provided by schools and faith-based organizations include safety and support, assessment, referral, and counseling. Exosystem interventions include those provided through community-based mental health programs, healthcare organizations, the workplace, the media, local volunteer disaster organizations, and other local organizations. Efforts to build community resilience to disasters are likely to have influence through the Exosystem. The Macrosystem – including the laws, history, cultural and subcultural characteristics, and economic and social conditions that underlie the other systems – affects the child indirectly through public policies and disaster programs and services that become available in the child’s Exosystem in the aftermath of a disaster. The social ecology paradigm, described more fully in a companion article (Noffsinger, Pfefferbaum, Pfefferbaum, Sherrieb, & Norris,2012), emphasizes relationships among systems and can guide the development and delivery of services embedded in naturally-occurring structures in the child’s environment.

    The social-ecological system (SES) approach to natural resource management holds enormous promise towards achieving sustainability. Despite this promise, social-ecological interactions are complex and elusive; they require simplification to guide effective application of the SES approach. The complex, adaptive and place-specific nature of human-environment interactions impedes determination of state and trends in SES parameters of interest to managers and policy makers. Based on a rigorously developed systemic theoretical model, this paper integrates field observations, interviews, surveys, and latent variable modeling to illustrate the development of simplified and easily interpretable indicators of the state of, and trends in, relevant SES processes. Social-agricultural interactions in the Logone floodplain, in the Lake Chad basin, served as case study. This approach is found to generate simplified determinants of the state of SESs, easily communicable across the array of stakeholders common in human-environment interactions. The approach proves to be useful for monitoring SESs, guiding interventions, and assessing the effectiveness of interventions. It incorporates real time responses to biophysical change in understanding coarse scale processes within which finer scales are embedded. This paper emphasizes the importance of merging quantitative and qualitative methods for effective monitoring and assessment of SESs.

    Availability of and access to useful energy is a crucial factor for maintaining and improving human well-being. Looming scarcities and increasing awareness of environmental, economic, and social impacts of conventional sources of non-renewable energy have focused attention on renewable energy sources, including biomass. The complex interactions of social, economic, and ecological factors among the bioenergy system components of feedstock supply, conversion technology, and energy allocation have been a major obstacle to the broader development of bioenergy systems. For widespread implementation of bioenergy to occur there is a need for an integrated approach to model the social, economic, and ecological interactions associated with bioenergy. Such models can serve as a planning and evaluation tool to help decide when, where, and how bioenergy systems can contribute to development. One approach to integrated modeling is by assessing the sustainability of a bioenergy system. The evolving nature of sustainability can be described by an adaptive systems approach using general systems principles. Discussing these principles reveals that participation of stakeholders in all components of a bioenergy system is a crucial factor for sustainability. Multi-criteria analysis (MCA) is an effective tool to implement this approach. This approach would enable decision-makers to evaluate bioenergy systems for sustainability in a participatory, transparent, timely, and informed manner. (author)

    Translating policies about sustainable development as a social process and sustainability outcomes into the real world of social-ecological systems involves several challenges. Hence, research policies advocate improved innovative problem-solving capacity. One approach is transdisciplinary research that integrates research disciplines, as well as researchers and practitioners. Drawing upon 14 experiences of problem-solving, we used group modeling to map perceived barriers and bridges for researchers' and practitioners' joint knowledge production and learning towards transdisciplinary research. The analysis indicated that the transdisciplinary research process is influenced by (1) the amount of traditional disciplinary formal and informal control, (2) adaptation of project applications to fill the transdisciplinary research agenda, (3) stakeholder participation, and (4) functional team building/development based on self-reflection and experienced leadership. Focusing on implementation of green infrastructure policy as a common denominator for the delivery of ecosystem services and human well-being, we discuss how to diagnose social-ecological systems, and use knowledge production and collaborative learning as treatments.

    The need for developing socially just living conditions for the world's growing population whilst keeping human societies within a 'safe operating space' has become a modern imperative. This requires transformative changes in the dominant social norms, behaviours, governance and management regimes that guide human responses in areas such as urban ecology, public health, resource security (e.g., food, water, energy access), economic development and biodiversity conservation. However, such systemic transformations necessitate experimentation in public arenas of exchange and a deepening of processes that can widen multi-stakeholder learning. We argue that there is an emergent potential in bridging the sustainability transitions and resilience approaches to create new scientific capacity that can support large-scale social-ecological transformations (SETs) to sustainability globally, not just in the West. In this article, we elucidate a set of guiding principles for the design of a 'safe space' to encourage stronger interactions between these research areas and others that are relevant to the challenges faced. We envisage new opportunities for transdisciplinary collaboration that will develop an adaptive and evolving community of practice. In particular, we emphasise the great opportunity for engaging with the role of emerging economies in facilitating safe space experimentation.

    Climate change is driving a pervasive global redistribution of the planet's species. Species redistribution poses new questions for the study of ecosystems, conservation science and human societies that require a coordinated and integrated approach. Here we review recent progress, key gaps and strategic directions in this nascent research area, emphasising emerging themes in species redistribution biology, the importance of understanding underlying drivers and the need to anticipate novel outcomes of changes in species ranges. We highlight that species redistribution has manifest implications across multiple temporal and spatial scales and from genes to ecosystems. Understanding range shifts from ecological, physiological, genetic and biogeographical perspectives is essential for informing changing paradigms in conservation science and for designing conservation strategies that incorporate changing population connectivity and advance adaptation to climate change. Species redistributions present challenges for human well-being, environmental management and sustainable development. By synthesising recent approaches, theories and tools, our review establishes an interdisciplinary foundation for the development of future research on species redistribution. Specifically, we demonstrate how ecological, conservation and social research on species redistribution can best be achieved by working across disciplinary boundaries to develop and implement solutions to climate change challenges. Future studies should therefore integrate existing and complementary scientific frameworks while incorporating social science and human-centred approaches. Finally, we emphasise that the best science will not be useful unless more scientists engage with managers, policy makers and the public to develop responsible and socially acceptable options for the global challenges arising from species redistributions. © 2017 Cambridge Philosophical Society.

  19. Environmental Governance for the Anthropocene? Social-Ecological Systems, Resilience, and Collaborative Learning

    Directory of Open Access Journals (Sweden)

    2017-07-01

    Full Text Available The Anthropocene is characterized by rapid global change, necessitating adaptive governance. But how can such adaptive governance be operationalized? The article offers a three-point argument to approach this question. First, people and environment need to be considered together, as social (human and ecological (biophysical subsystems are linked by mutual feedbacks, and are interdependent and co-evolutionary. These integrated systems of humans and environment (social-ecological systems provide an appropriate unit of analysis. Second, the resilience approach deals with change in multilevel complex systems, and has stimulated much of the adaptive governance literature by addressing uncertainty and adaptation to unforeseen future changes. Third, there is a need to foster collaborative approaches to improve social and institutional learning, as for example in adaptive management, collaborative learning networks, and knowledge co-production. Collaborative learning is perhaps where further research, experimentation, and application might make a difference for operationalizing adaptive governance, with a focus on institutions, at all levels from local to international.

    2013-09-01

    Full Text Available By integrating the research and resources of hundreds of scientists from dozens of institutions, network-level science is fast becoming one scientific model of choice to address complex problems. In the pursuit to confront pressing environmental issues such as climate change, many scientists, practitioners, policy makers, and institutions are promoting network-level research that integrates the social and ecological sciences. To understand how this scientific trend is unfolding among rising scientists, we examined how graduate students experienced one such emergent social-ecological research initiative, Integrated Science for Society and Environment, within the large-scale, geographically distributed Long Term Ecological Research (LTER Network. Through workshops, surveys, and interviews, we found that graduate students faced challenges in how they conceptualized and practiced social-ecological research within the LTER Network. We have presented these conceptual challenges at three scales: the individual/project, the LTER site, and the LTER Network. The level of student engagement with and knowledge of the LTER Network was varied, and students faced different institutional, cultural, and logistic barriers to practicing social-ecological research. These types of challenges are unlikely to be unique to LTER graduate students; thus, our findings are relevant to other scientific networks implementing new social-ecological research initiatives.

    Full Text Available Tourism is an important sector in developing countries to support economic growth, and coastal areas are famous destinations in tourism. The plan and design for Balekambang coastal area as a tourism destination in East Java, Indonesia has been formulated and published. However, it seems lack ecological and social perspectives. This study examines coral reefs structure as one of the ecological parameter and tourist perspectives as social parameter for destination development evaluation. Twenty belt-transects were established along Balekambang coastline, and then divided into three sections, the east, the centre and the west sections. Every belt-transect was 200m in length and consists of 15 plots 1 x 2m. The tourist perspectives to Balekambang were determined using questionnaire among 234 respondents. Based on the Morisita similarity index, the coral reef of east section consists of 2 zones, the centre consists of 5 zones and west section consists of 4 zones. The Shannon diversity index (H’ among zones at every location was ranged. The diversity index of the east section ranged from 2.07 to 2.72, the central section ranged from 1.32 to 4.20, and the west section ranged from 3.13 to 4.20. Zones that were close to the coastline had lowest diversity indices than zones that located far from the coastline. Mostly, tourists stated that Balekambang was interesting, but the object of tourism should be added. Respondent knew there were forest surrounding Balekambang, and it has the possibility to develop as tourism destination. These findings argue that the forest conversion to cottage area that planned by the local government in the west section should be reviewed. It seems forest in the west section should be developed as a forest park to meet tourist needs and redistribute tourist concentration in the coastline. Keywords: Ecological and social evaluation, coastal, tourism, sustainable development, East Java.

  3. A Social-Ecological Framework of Theory, Assessment, and Prevention of Suicide

    2017-10-01

    Full Text Available The juxtaposition of increasing suicide rates with continued calls for suicide prevention efforts begs for new approaches. Grounded in the Centers for Disease Control and Prevention (CDC framework for tackling health issues, this personal views work integrates relevant suicide risk/protective factor, assessment, and intervention/prevention literatures. Based on these components of suicide risk, we articulate a Social-Ecological Suicide Prevention Model (SESPM which provides an integration of general and population-specific risk and protective factors. We also use this multi-level perspective to provide a structured approach to understanding current theories and intervention/prevention efforts concerning suicide. Following similar multi-level prevention efforts in interpersonal violence and Human Immunodeficiency Virus (HIV domains, we offer recommendations for social-ecologically informed suicide prevention theory, training, research, assessment, and intervention programming. Although the SESPM calls for further empirical testing, it provides a suitable backdrop for tailoring of current prevention and intervention programs to population-specific needs. Moreover, the multi-level model shows promise to move suicide risk assessment forward (e.g., development of multi-level suicide risk algorithms or structured professional judgments instruments to overcome current limitations in the field. Finally, we articulate a set of characteristics of social-ecologically based suicide prevention programs. These include the need to address risk and protective factors with the strongest degree of empirical support at each multi-level layer, incorporate a comprehensive program evaluation strategy, and use a variety of prevention techniques across levels of prevention.

    2010-01-01

    Now that racism has been officially recognized in Brazil, and some universities have adopted affirmative-action admission policies, measures of the magnitude of racial inequality and analyses that identify the factors associated with changes in racial disparities over time assume particular relevance to the conduct of public debate. This study uses census data from 1950 to 2000 to estimate the probability of death in the early years of life, a robust indicator of the standard of living among the white and Afro-Brazilian populations. Associated estimates of the average number of years of life expectancy at birth show that the 6.6-year advantage that the white population enjoyed in the 1950s remained virtually unchanged throughout the second half of the twentieth century, despite the significant improvements that accrued to both racial groups. The application of multivariate techniques to samples selected from the 1960, 1980, and 2000 census enumerations further shows that, controlling for key determinants of child survival, the white mortality advantage persisted and even increased somewhat in 2000. The article discusses evidence of continued racial inequality during an era of deep transformation in social structure, with reference to the challenges of skin color classification in a multiracial society and the evolution of debates about color, class, and discrimination in Brazil.

    The aim of this study was to describe quality indicators for prenatal care in Brazil as part of the Program for the Improvement of Access and Quality (PMAQ-AB). The study analyzed number of prenatal visits, vaccination status, prescription of ferrous sulfate, physical examination, orientation, and laboratory tests, based on which a summary quality indicator was constructed. Data were collected in 2012-2013 during interviews conducted by External Evaluators of the PMAQ-AB, with 6,125 users who had done their last prenatal follow-up in Family Health units. During prenatal follow-up, 89% reported six or more visits, more than 95% received a tetanus booster and prescription of ferrous sulfate, 24% reported having received all the procedures in the physical examination, 60% received all the orientation, and 69% had all the recommended laboratory tests. Only 15% of interviewees had received adequate prenatal care, including all the recommended measures, and there was a significantly higher proportion of "complete" care in pregnant women that were older, with higher income, in the Southeast region of Brazil, in municipalities with more than 300,000 inhabitants, and in those with (HDI) in the upper quartile. There are persist social and individual inequalities that can be targeted by measures to upgrade the teams' work processes.

    2009-09-01

    This article offers a brief description and analysis of public participation in health in Brazil and England in order to highlight different motivators and tensions within an acceptance of participation as official policy. The article draws on a range of research in both countries and an analysis of official documents relating to participation. It is based on collaboration between researchers deriving from broad programmes of work on public participation in which the authors are involved. There is a tension between different principles underpinning collective public involvement in health both within and between countries. Different aspirations or claims have been made about what such participation will achieve and there are trade-offs between design principles that have consequences for issues such as who takes part and thus also for what can be achieved. The democratic origins of public participation are more evident in the Brazilian situation than in England, but there are still questions about the inclusivity of the practices through which this is achieved. The English picture is both more diverse and dynamic, but formal decision-making power of participatory forums is less than in Brazil. Whilst social justice claims for participation have been made in both countries, there is as yet limited evidence that these have been realized.

  8. The problem of spatial fit in social-ecological systems: detecting mismatches between ecological connectivity and land management in an urban region

    2014-12-01

    Full Text Available The problem of institutional fit in social-ecological systems has been empirically documented and conceptually discussed for decades, yet there is a shortage of approaches to systematically and quantitatively examine the level of fit. We address this gap, focusing on spatial fit in an urban and peri-urban regional landscape. Such landscapes typically exhibit significant fragmentation of remnant habitats, which can limit critical species dispersal. This may have detrimental effects on species persistence and ecosystem functioning if land use is planned without consideration of the spatial patterns of fragmentation. Managing habitat fragmentation is particularly challenging when the scale of fragmentation reaches beyond the control of single managers, thereby requiring different actors to coordinate their activities to address the problem at the appropriate scale. We present a research approach that maps patterns of collaborations between actors who manage different parts of a landscape, and then relates these patterns to structures of ecological connectivity. We applied our approach to evaluate the fit between a collaborative wetland management network comprising all 26 municipalities in the Stockholm County in Sweden and an ecologically defined network of dispersed but ecologically interconnected wetlands. Many wetlands in this landscape are either intersected by the boundary between two or more municipalities, or are located close to such boundaries, which implies a degree of ecological interconnectedness and a need for intermunicipal coordination related to wetland management across boundaries. We first estimated the level of ecological connectivity between wetlands in neighboring municipalities, and then used this estimate to elaborate the level of social-ecological fit vis-à-vis intermunicipal collaboration. We found that the level of fit was generally weak. Also, we identified critical misalignments of ecological connectivity and

    Full Text Available This paper shows that youth involvement in groups, in this case the public policies that reflect the environment is a fertile opportunity to form social subjects. In this sense, it also shows that non-formal education is, outside of school is an effective tool for behavior change among youth, and in Brazil this kind of public investment contributes significantly to improve the youth level in many ways, particularly in implementing the National Environmental Education Policy, including with respect to the far-reaching policy decisions. The areas of participation, called councils, commissions, conferences, are spaces that primarily exist to perform the role of educator or educational structures space. The existence of these structures such as councils, groups, committees and networks is urgently needed. However, not enough to exert its educational role. It is essential to continuous development and ongoing activities, reflection and action.

    2011-08-01

    Discussions on the health-disease process and health promotion indicate the need to reach beyond the limits of the health sector itself to link knowledge from various fields in order to promote better health conditions for the population. Inter-sector approaches have thus emerged as a new rationale for guiding public policies. This study aimed to analyze the implementation of inter-sector actions in social mobilization for dengue control in Bahia State, Brazil, from 2008 to 2009, using evaluative research. A log frame was developed to define criteria for assessing the degree of implementation of the above-mentioned actions (implemented; partially implemented; not implemented). The results identified political support from government agencies as the main positive factor for inter-sector practices. Barriers included the concentration of responsibilities in a single sector and lack of planning as a work tool. The results emphasize inter-sector linkage as a persistent challenge.

    Full Text Available In recent years, the border shared by Peru, Colombia and Brazil has become an enclave of drug production and trafficking for the international markets. It is a territory whose control is disputed by non-state actors and where state security forces suffer from severe material and transport limitations. This paper takes an ethnographic approach to explain the limitations of border security and the institutional challenges of controlling drug and wood trafficking in this context. It places the ideas of reproduction and social change at the centre of the discussion on drugs and borders, as key ways of thinking about the dynamics of growing and processing coca-derived drugs in the global South.

    Efforts to change policies and the environments in which people live, work, and play have gained increasing attention over the past several decades. Yet health promotion frameworks that illustrate the complex processes that produce health-enhancing structural changes are limited. Building on the experiences of health educators, community activists, and community-based researchers described in this supplement and elsewhere, as well as several political, social, and behavioral science theories, we propose a new framework to organize our thinking about producing policy, environmental, and other structural changes. We build on the social ecological model, a framework widely employed in public health research and practice, by turning it inside out, placing health-related and other social policies and environments at the center, and conceptualizing the ways in which individuals, their social networks, and organized groups produce a community context that fosters healthy policy and environmental development. We conclude by describing how health promotion practitioners and researchers can foster structural change by (1) conveying the health and social relevance of policy and environmental change initiatives, (2) building partnerships to support them, and (3) promoting more equitable distributions of the resources necessary for people to meet their daily needs, control their lives, and freely participate in the public sphere. © 2015 Society for Public Health Education.

    Full Text Available The objective of this paper is to provide a preliminary discussion of how to improve our conceptualization of social thresholds using (1 a more sociological analysis of social resilience, and (2 results from research carried out in collaboration with the Champagne and Aishihik First Nations of the Yukon Territory, Canada. Our sociological analysis of the concept of resilience begins with a review of the literature followed by placement of the concept in the domain of sociological theory to gain insight into its strengths and limitations. A new notion of social thresholds is proposed and case study research discussed to support the proposition. Our findings suggest that rather than view social thresholds as breakpoints between two regimes, as thresholds are typically conceived in the resilience literature, that they be viewed in terms of collectively recognized points that signify new experiences. Some examples of thresholds identified in our case study include power in decision making, level of healing from historical events, and a preference for small-scale development over large capital intensive projects.

    In urban communities, arboriculture clearly contributes to the health of the biological ecosystem; does it contribute to the health of the social ecosystem as well? Evidence from studies in inner-city Chicago suggests so.

    2003-07-01

    Industrial Ecology is a new term for an idea that arose in the nineteenth century, that of looking at the economy in terms of social metabolism. This implies to perceive the economy as a open to the entry of energy and materials, and to the exit of waste and dissipated heat. Nowadays there is empirical work on social metabolism at the corporations level and of the whole economy. This article summarized the work of some authors, pioneers in the fields of agricultural energetics and urban ecology. It also reconstructs the debated between a social metabolic approach and both Marxian and neoclassical economics approaches. (Author) 78 refs.

    Full Text Available This article addresses issues related to the staff of Post-Graduate programs in Social Work in Brazil. Initially, it traces a retrospective of Post-Graduate education in the country and describes the structure of Social Work in three moments: the initial period, through the 1970’s and 1980’s; the period of expansion, between 1990 and 2005; and the current period, between 2006 and 2016. It points out the impasses experienced by the first programs in relation to the lack of Doctors. Next, it presents the current profile of the professors who are part of Social Work programs. Data were obtained from CAPES, Geocapes and program reports, and analyzed through descriptive statistical analysis and content analysis. In conclusion, it evidences a growing tendency towards qualification and a marked expansion of the number of teaching staff after the year 2000. The growth of doctoral courses is noteworthy, however, the relation between teaching staff and students did not change significantly in percentage terms.

    Science has a critical role to play in guiding more sustainable development trajectories. Here, we present the Sustainable Amazon Network (Rede Amazônia Sustentável, RAS): a multidisciplinary research initiative involving more than 30 partner organizations working to assess both social and ecological dimensions of land-use sustainability in eastern Brazilian Amazonia. The research approach adopted by RAS offers three advantages for addressing land-use sustainability problems: (i) the collection of synchronized and co-located ecological and socioeconomic data across broad gradients of past and present human use; (ii) a nested sampling design to aid comparison of ecological and socioeconomic conditions associated with different land uses across local, landscape and regional scales; and (iii) a strong engagement with a wide variety of actors and non-research institutions. Here, we elaborate on these key features, and identify the ways in which RAS can help in highlighting those problems in most urgent need of attention, and in guiding improvements in land-use sustainability in Amazonia and elsewhere in the tropics. We also discuss some of the practical lessons, limitations and realities faced during the development of the RAS initiative so far. PMID:23610172

    Full Text Available Indigenous peoples of North America, Australia, and New Zealand have a long tradition of harvesting freshwater animals. Over generations of reliance and subsistence harvesting, Indigenous peoples have acquired a profound understanding of these freshwater animals and ecosystems that have become embedded within their cultural identity. We have identified trans-Pacific parallels in the cultural significance of several freshwater animal groups, such as eels, other finfish, bivalves, and crayfish, to Indigenous peoples and their understanding and respect for the freshwater ecosystems on which their community survival depends. In recognizing such cultural connections, we found that non-Indigenous peoples can appreciate the deep significance of freshwater animals to Indigenous peoples and integrate Indigenous stewardship and Indigenous ecological knowledge into effective comanagement strategies for sustainable freshwater fisheries, such as Indigenous rangers, research partnerships, and Indigenous Protected Areas. Given that many of these culturally significant freshwater species also play key ecological roles in freshwater ecosystems, their recognition and prioritization in management and monitoring approaches should help sustain the health and well-being of both the social and ecological components of freshwater ecosystems.

    The demand for gender analysis is now increasingly orthodox in natural resource programming, including that for small-scale fisheries. Whilst the analysis of social-ecological resilience has made valuable contributions to integrating social dimensions into research and policy-making on natural resource management, it has so far demonstrated limited success in effectively integrating considerations of gender equity. This paper reviews the challenges in, and opportunities for, bringing a gender analysis together with social-ecological resilience analysis in the context of small-scale fisheries research in developing countries. We conclude that rather than searching for a single unifying framework for gender and resilience analysis, it will be more effective to pursue a plural solution in which closer engagement is fostered between analysis of gender and social-ecological resilience whilst preserving the strengths of each approach. This approach can make an important contribution to developing a better evidence base for small-scale fisheries management and policy.

    Full Text Available OBJECTIVE: To study patterns of alcohol consumption and prevalence of high-risk drinking. METHODS: A household survey was carried out in a sample of 2,302 adults in Salvador, Brazil. Cases of High-Risk Drinking (HRD were defined as those subjects who referred daily or weekly binge drinking plus episodes of drunkenness and those who reported any use of alcoholic beverages but with frequent drunkenness (at least once a week. RESULTS: Fifty-six per cent of the sample acknowledged drinking alcoholic beverages. Overall consumption was significantly related with gender (male, marital status (single, migration (non-migrant, better educated (college level, and social class (upper. No significant differences were found regarding ethnicity, except for cachaça (Brazilian sugarcane liquor and other distilled beverages. Overall 12-month prevalence of high-risk drinking was 7%, six times more prevalent among males than females (almost 13% compared to 2.4%. A positive association of HRD prevalence with education and social class was found. No overall relationship was found between ethnicity and HRD. Male gender and higher socioeconomic status were associated with increased odds of HRD. Two-way stratified analyses yielded consistent gender effects throughout all strata of independent variables. CONCLUSIONS: The findings suggest that social and cultural elements determine local patterns of alcohol-drinking behavior. Additional research on long-term and differential effects of gender, ethnicity, and social class on alcohol use and misuse is needed in order to explain their role as sources of social health inequities.

    To determine the prevalence of temporary social security benefits due to respiratory disease granted to employees, as well as the number of lost workdays and costs resulting from those in Brazil between 2003 and 2004. Cross-sectional study using data obtained from the Unified System of Benefits of the Brazilian Institute of Social Security (INSS, Instituto Nacional de Seguro Social) and the Brazilian Social Registry Database. Data regarding gender, age, diagnosis and type of economic activity, as well as type, duration and cost of benefits, were compiled. Respiratory diseases accounted for 1.3% of the total number of temporary social security benefits granted by INSS, with a prevalence rate of 9.92 (per 10,000 employment contracts). Females and individuals older than 50 years of age were the most affected. Non-work-related benefits were more common than were work-related benefits. The most prevalent diseases were pneumonia, asthma and COPD, followed by laryngeal and vocal cord diseases. The most prevalent types of economic activity were auxiliary transportation equipment manufacturing, tobacco product manufacturing and computer-related activities. The mean duration of benefits was 209.68 days, with a mean cost of R$ 4,495.30 per occurrence. Respiratory diseases caused by exogenous agents demanded longer sick leave (mean, 296.72 days) and greater cost (mean, R$ 7,105.74). The most prevalent diseases were airway diseases and pneumonia. Workers from auxiliary transportation equipment manufacturing, tobacco product manufacturing and computer-related activities were the most affected. Diseases caused by exogenous agents demanded longer sick leaves and resulted in greater costs.

    Full Text Available Today's multifaceted environmental problems, including climate change, necessitate interdisciplinary research. It is however difficult to combine disciplines to study such complex phenomena. We analyzed the experience we gained in applying a particular method of interdisciplinary integration, the 'bridging concept.' We outlined the entire process of developing, utilizing, and adapting social-ecological resilience as a bridging concept in a research project involving seven different disciplines. We focused on the tensions and opportunities arising from interdisciplinary dialogue and the understandings and manifestations of resilience in the disciplines involved. By evaluating the specific cognitive and social functions of resilience as a method of integration, we call for placing greater emphasis on the quality and value of the actual interdisciplinary process, rather than concentrating solely on the output of interdisciplinary work.

    2017-06-01

    Full Text Available Risks have been classically understood as a probability of damage or a potential hazard resulting in appropriate management strategies. However, research on environmental issues such as pollutants in the aquatic environment or the impacts of climate change have shown that classical management approaches do not sufficiently cover these interactions between society and nature. There have been several attempts to develop interdisciplinary approaches to risk that include natural as well as social science contributions. In this paper, the authors aim at developing a social-ecological perspective on risk by drawing on the concept of societal relations to nature and the model of provisioning systems. This perspective is used to analyze four cases, pharmaceuticals, microplastics, semicentralized water infrastructures and forest management, with regard to risk identification, assessment and management. Finally, the paper aims at developing a perspective on risks which takes into account non-intended side-effects, system interdependencies and uncertainty.

    Full Text Available Management decisions for natural resources are not made in a vacuum; the environmental and ecological conditions as well as the socioeconomic and political contexts affect goals, the choice of interventions, their feasibility, and which outcomes are obtained. Although uncertainty is recognized as a feature of natural resource management, little attention has been given to the uncertainty generated by institutional settings, historical contingency, and individual people's influence. These implementation uncertainties, related to the translation of policy into practice, make it difficult to predict the outcomes of management interventions within social-ecological systems. Using the conservation of species hunted for bushmeat in the Serengeti as a case study, we investigated the challenges and potential barriers to successful implementation of natural resource management policies. We used a mixed-methods approach, combining semistructured interviews with scenario building, social network, and institutional analysis exercises. Using a management strategy evaluation (MSE conceptual framework, we obtained insights into the constraints and opportunities for fulfilling stakeholder aspirations for the social-ecological system, analyzed the multiple roles played by different institutions in the system, and described the interactions between different actor types. We found that the respondents had generally similar views about the current and future status of the Serengeti but disagreed about how to address issues of conservation concern and were more uncertain about the actual outcomes of management interventions. Improving conservation implementation (rather than research, monitoring, or status assessment was perceived as the key priority to be addressed. Institutional barriers were perceived as an important challenge given that the decision-making and implementation processes were broadly distributed across a number of institutions.

    Full Text Available In the last eight years (2008-2016, some areas in the northern part of Pekalongan have been experiencing coastal inundation. There have been social, economic and physical disruptions caused by coastal inundation particularly on built environments, paddy fields, and fishpond. The capacity of these areas to provide support for community livelihood has decreased significantly. This accumulative environmental change leads to the emerging of vulnerable regions which are characterized by limited social and ecological capability in responding to hazards. In order to enhance the social-ecological resilience, it is necessary to identify how these communities elevate their capacity and improve their livelihood. This paper presents empirical evidence of various pathways on how the community has transformed their capacity to respond to the changing environment due to coastal inundation. Using a case study approach, this paper explores on how the community has learned from their experiences, knowledge, and efforts withdrawn from the past, and then turns them into a better understanding to cope with, to adapt to, and to become resilient from coastal inundation. In-depth interviews with several key persons who are selected by purposive and snowballing sampling method are employed. These key persons represent the most capable person in each sub-district who poses some important data and information related to coastal inundation either as the individual, household members, or community organization members. The scope of area observation is limited to six sub-districts which adjacent to the coast in the North Pekalongan District. This research employs inductive approach and manual coding technique. The research demonstrates that social-ecological resilience will likely enhance in a community which is capable of nurturing flexible networking. Such networking has made it possible for important information, novel knowledge and practical tools and solutions spread

  10. Social vulnerability from a social ecology perspective: a cohort study of older adults from the National Population Health Survey of Canada

    2014-01-01

    Background Numerous social factors, generally studied in isolation, have been associated with older adults’ health. Even so, older people’s social circumstances are complex and an approach which embraces this complexity is desirable. Here we investigate many social factors in relation to one another and to survival among older adults using a social ecology perspective to measure social vulnerability among older adults. Methods 2740 adults aged 65 and older were followed for ten years in the Canadian National Population Health Survey (NPHS). Twenty-three individual-level social variables were drawn from the 1994 NPHS and five Enumeration Area (EA)-level variables were abstracted from the 1996 Canadian Census using postal code linkage. Principal Component Analysis (PCA) was used to identify dimensions of social vulnerability. All social variables were summed to create a social vulnerability index which was studied in relation to ten-year mortality. Results The PCA was limited by low variance (47%) explained by emergent factors. Seven dimensions of social vulnerability emerged in the most robust, yet limited, model: social support, engagement, living situation, self-esteem, sense of control, relations with others and contextual socio-economic status. These dimensions showed complex inter-relationships and were situated within a social ecology framework, considering spheres of influence from the individual through to group, neighbourhood and broader societal levels. Adjusting for age, sex, and frailty, increasing social vulnerability measured using the cumulative social vulnerability index was associated with increased risk of mortality over ten years in a Cox regression model (HR 1.04, 95% CI:1.01-1.07, p = 0.01). Conclusions Social vulnerability has important independent influence on older adults’ health though relationships between contributing variables are complex and do not lend themselves well to fragmentation into a small number of discrete factors.

    To describe associations between pregnancy rates in adolescence and socioeconomic and social responsibility indicators in the municipalities of the State of Minas Gerais, Southeast of Brazil, in the year of 2010. Ecological study using data from the Brazilian Live Birth Information System (SINASC). The percentage of live births to adolescent mothers (LBAM) for each municipality was calculated based on the quotient between number of born alive infants of mothers aged 10-19 years old and total number of live births in the year of 2010. Fully Bayesian models were used to obtain the percentages of LBAM adjusted for spatial effects and to assess possible associations with socioeconomic and social responsibility indicators. The crude percentage of LBAM for the total number of live births in the municipalities of Minas Gerais in 2010 ranged from 0 to 46.4%, with median percentage being 19.6% and the first and third quartiles being 15.6 and 23.1%, respectively. This study has demonstrated a close relationship between adolescent pregnancy and socioeconomic indicators. LBAM percentages were found to be higher in municipalities with low population density, low human development index and other low development indicators. The strong relationship between LBAM percentages and socioeconomic indicators suggests that adolescent pregnancy is more a social than a biological problem. Therefore, programs and actions should go beyond sexual education and information on preventive health methods.

    Across the Americas, biofuels production systems are diverse due to geographic conditions, historical patterns of land tenure, different land use patterns, government policy frameworks, and relations between the national state and civil society, all of which shape the role that biofuels play in individual nations. Although many national governments throughout the Americas continue to incentivize growth of the biofuels industry, one key challenge for biofuels sustainability has been concern about its social impacts. In this article, we discuss some of the key social issues and tensions related to the recent expansion of biofuels production in Mexico, Colombia, and Brazil. We argue that a process of "simplification" of ecological and cultural diversity has aided the expansion of the biofuels frontier in these countries, but is also undermining their viability. We consider the ability of governments and non-state actors in multi-stakeholder initiatives (MSI) to address social and environmental concerns that affect rural livelihoods as a result of biofuels expansion. We analyze the tensions between global sustainability standards, national level policies for biofuels development, and local level impacts and visions of sustainability. We find that both government and MSI efforts to address sustainability concerns have limited impact, and recommend greater incorporation of local needs and expertise to improve governance.

    In the anthropocene, the rise of global social and economic networks with ever increasing connectivity and speed of interactions, e.g., the internet or global financial markets, is a key challenge for sustainable development. The spread of opinions, values or technologies on these networks, in conjunction with the coevolution of the network structures themselves, underlies nexuses of current concern such as anthropogenic climate change, biodiversity loss or global land use change. To isolate and quantitatively study the effects and implications of network dynamics for sustainable development, we propose an agent-based model of information flow on adaptive networks between myopic harvesters that exploit private renewable resources. In this conceptual model of a network of socio-ecological systems, information on management practices flows between agents via boundedly rational imitation depending on the state of the resource stocks involved in an interaction. Agents can also adapt the structure of their social network locally by preferentially connecting to culturally similar agents with identical management practices and, at the same time, disconnecting from culturally dissimilar agents. Investigating in detail the statistical mechanics of this model, we find that an increasing rate of information flow through faster imitation dynamics or growing density of network connectivity leads to a marked increase in the likelihood of environmental resource collapse. However, we show that an optimal rate of social network adaptation can mitigate this negative effect without loss of social cohesion through network fragmentation. Our results highlight that seemingly immaterial network dynamics of spreading opinions or values can be of large relevance for the sustainable management of socio-ecological systems and suggest smartly conservative network adaptation as a strategy for mitigating environmental collapse. Hence, facing the great acceleration, these network dynamics should

    Alcohol use and misuse account for 3.3 million deaths every year, or 6 percent of all deaths worldwide. The harmful effects of alcohol misuse are far reaching and range from individual health risks, morbidity, and mortality to consequences for family, friends, and the larger society. This article reviews a few of the cultural and social influences on alcohol use and places individual alcohol use within the contexts and environments where people live and interact. It includes a discussion of macrolevel factors, such as advertising and marketing, immigration and discrimination factors, and how neighborhoods, families, and peers influence alcohol use. Specifically, the article describes how social and cultural contexts influence alcohol use/misuse and then explores future directions for alcohol research.

  16. Meanings and robustness: Propositions for enhancing benefit sharing in social-ecological systems

    Full Text Available Given increased pressure on natural resources to deliver benefits, complex trade-offs and the regulation of behaviours in relation to benefits is of key concern. Behaviours that signify resistance to the rules according to which benefits are allocated prompt us to consider causal links and feedbacks between benefits, perceptions of benefits, meanings attached to the benefits, and the regulatory instruments that mediate the distribution of benefits. An understanding of how meanings influence the perception of benefits exposes the complexity inherent in how people perceive and allocate value to natural resource benefits. Meanings are personal, sometimes overlapping, context dependent and variable across space and time. A challenge in directing resource user behaviour in common pool resources is that the relationship between the resource and resource use is typically not interpreted to include the manner in which users associate resource benefits with meanings. We propose that collective ordering of meanings and associated rules help to direct behaviours and in doing so they contribute to the purposeful maintenance of desirable elements of a social-ecological system (i.e. robustness. Using an example, we illustrate how tensions around benefit sharing are rooted in the emergence and changing prioritisation of contexts and meanings over time. The importance of eliciting, ordering and sanctioning of meanings is emphasised. We conclude by discussing the implications for robustness and benefit sharing in social-ecological systems and we comment on the usefulness and limitations of the framework.

    1. Social network analyses tend to focus on human interactions. However, there is a burgeoning interest in applying graph theory to ecological data from animal populations. Here we show how radio-tracking and capture-mark-recapture data collated from wild rodent populations can be used to generate contact networks. 2. Both radio-tracking and capture-mark-recapture were undertaken simultaneously. Contact networks were derived and the following statistics estimated: mean-contact rate, edge distribution, connectance and centrality. 3. Capture-mark-recapture networks produced more informative and complete networks when the rodent density was high and radio-tracking produced more informative networks when the density was low. Different data collection methods provide more data when certain ecological characteristics of the population prevail. 4. Both sets of data produced networks with comparable edge (contact) distributions that were best described by a negative binomial distribution. Connectance and closeness were statistically different between the two data sets. Only betweenness was comparable. The differences between the networks have important consequences for the transmission of infectious diseases. Care should be taken when extrapolating social networks to transmission networks for inferring disease dynamics.

    Full Text Available The complexity of social-ecological systems is well recognized (Berkes et al. 2003, Norberg and Cumming 2008. However, in the study of such systems, it is often the uncertainty that results from nonlinear interactions that forms the focus of discussion. Here, the normative implications of complexity for our knowledge of such systems are emphasised, by drawing largely on the work of Cilliers (1998, 2005a, who introduced the term "critical complexity." This perspective on complexity is distinct in bringing the value-based choices that frame our knowledge generation strategies to the fore. It is from this view that we investigate the implications of complexity for social-ecological systems research. Based on these implications, we propose a set of five key questions to guide the incorporation of insights from critical complexity into such research. We end with a brief application of the questions proposed to the National Freshwater Ecosystem Priority Areas (NFEPA project in South Africa, to illustrate their potential use in the context of resource management.

    Full Text Available The case studies of Kristianstads Vattenrike, Sweden; the Northern Highlands Lake District and the Everglades in the USA; the Mae Nam Ping Basin, Thailand; and the Goulburn-Broken Catchment, Australia, were compared to assess the outcome of different actions for transforming social-ecological systems (SESs. The transformations consisted of two phases, a preparation phase and a transition phase, linked by a window of opportunity. Key leaders and shadow networks can prepare a system for change by exploring alternative system configurations and developing strategies for choosing from among possible futures. Key leaders can recognize and use or create windows of opportunity and navigate transitions toward adaptive governance. Leadership functions include the ability to span scales of governance, orchestrate networks, integrate and communicate understanding, and reconcile different problem domains. Successful transformations rely on epistemic and shadow networks to provide novel ideas and ways of governing SESs. We conclude by listing some ð"„¬rules of thumb" that can help build leadership and networks for successful transformations toward adaptive governance of social-ecological systems.

  20. Virtual Reality for Enhanced Ecological Validity and Experimental Control in the Clinical, Affective and Social Neurosciences

    An essential tension can be found between researchers interested in ecological validity and those concerned with maintaining experimental control. Research in the human neurosciences often involves the use of simple and static stimuli lacking many of the potentially important aspects of real world activities and interactions. While this research is valuable, there is a growing interest in the human neurosciences to use cues about target states in the real world via multimodal scenarios that involve visual, semantic, and prosodic information. These scenarios should include dynamic stimuli presented concurrently or serially in a manner that allows researchers to assess the integrative processes carried out by perceivers over time. Furthermore, there is growing interest in contextually embedded stimuli that can constrain participant interpretations of cues about a target’s internal states. Virtual reality environments proffer assessment paradigms that combine the experimental control of laboratory measures with emotionally engaging background narratives to enhance affective experience and social interactions. The present review highlights the potential of virtual reality environments for enhanced ecological validity in the clinical, affective, and social neurosciences. PMID:26696869

    Full Text Available Complexity thinking is increasingly being embraced by a wide range of academics and professionals as imperative for dealing with today's pressing social-ecological challenges. In this context, action researchers partner directly with stakeholders (communities, governance institutions, and work resource managers, etc. to embed a complexity frame of reference for decision making. In doing so, both researchers and stakeholders must strive to internalize not only "intellectual complexity" (knowing but also "lived complexity" (being and practicing. Four common conceptualizations of learning (explicit/tacit knowledge framework; unlearning selective exposure; conscious/competence learning matrix; and model of learning loops are integrated to provide a new framework that describes how learning takes place in complex systems. Deep reflection leading to transformational learning is required to foster the changes in mindset and behaviors needed to adopt a complexity frame of reference. We then present three broad frames of mind (openness, situational awareness, and a healthy respect for the restraint/action paradox, which each encompass a set of habits of mind, to create a useful framework that allows one to unlearn reductionist habits while adopting and embedding those more conducive to working in complex systems. Habits of mind provide useful heuristic tools to guide researchers and stakeholders through processes of participative planning and adaptive decision making in complex social-ecological systems.

    As a dominant land use in urban ecosystems, residential yards impact water and other environmental resources. Converting thirsty lawns into alternative landscapes is one approach to water conservation, yet barriers such as cultural norms reinforce the traditional lawn. Meanwhile, the complex social and ecological implications of yard choices complicate programs aimed at changing grass and other yard features for particular purposes. In order to better understand individual landscape decisions, we qualitatively examined residents’ rationales for their preferred yard types in the desert metropolis of Phoenix, Arizona. After briefly presenting landscape choices across two survey samples, the dominant reasons for preferences are discussed: appearance, maintenance, environment, recreation, microclimate, familiarity, and health/safety. Three broader analytical themes emerged from these descriptive codes: (1) residents’ desires for attractive, comfortable landscapes of leisure encompassing pluralistic tastes, lifestyles, and perceptions; (2) the association of environmental benefits and impacts with different landscape types involving complex social and ecological tradeoffs; and (3) the cultural legacies evident in modern landscape choices, especially in terms of a dichotomous human-nature worldview among long-time residents of the Phoenix oasis. Given these findings, programs aimed at landscape change must recognize diverse preferences and rationalization processes, along with the perceived versus actual impacts and tradeoffs of varying yard alternatives.

    In this article we summarize histories of nonlinear, complex interactions among societal, legal, and ecosystem dynamics in six North American water basins, as they respond to changing climate. These case studies were chosen to explore the conditions for emergence of adaptive governance in heavily regulated and developed social-ecological systems nested within a hierarchical governmental system. We summarize resilience assessments conducted in each system to provide a synthesis and reference by the other articles in this special feature. We also present a general framework used to evaluate the interactions between society and ecosystem regimes and the governance regimes chosen to mediate those interactions. The case studies show different ways that adaptive governance may be triggered, facilitated, or constrained by ecological and/or legal processes. The resilience assessments indicate that complex interactions among the governance and ecosystem components of these systems can produce different trajectories, which include patterns of (a) development and stabilization, (b) cycles of crisis and recovery, which includes lurches in adaptation and learning, and (3) periods of innovation, novelty, and transformation. Exploration of cross scale (Panarchy) interactions among levels and sectors of government and society illustrate that they may constrain development trajectories, but may also provide stability during crisis or innovation at smaller scales; create crises, but may also facilitate recovery; and constrain system transformation, but may also provide windows of opportunity in which transformation, and the resources to accomplish it, may occur. The framework is the starting point for our exploration of how law might play a role in enhancing the capacity of social-ecological systems to adapt to climate change.

    Full Text Available We propose and illustrate a multi-scale integrated analysis of societal and ecosystem metabolism (MuSIASEM as a tool to bring nexus thinking into practice. MuSIASEM studies the relations over the structural and functional components of social-ecological systems that determine the entanglement of water, energy, and food flows in a complex metabolic pattern. MuSIASEM simultaneously considers various dimensions and multiple scales of analysis and therefore avoids the predicament of quantitative analysis based on reductionism (one dimension and one scale at the time. The different functional elements of society (the parts are characterized using the concept of “processor,” that is, a profile of expected inputs and outputs associated with the expression of a specific function. The processors of the functional elements of the social-ecological system can be either scaled-up to describe the metabolic pattern of the system as a whole, or scaled-down by considering the characteristics of its lower-level parts—i.e., the different processors associated with the structural elements required to express the specific function. An analysis of functional elements provides insight in the socio-economic factors that pose internal constraints on the development of the system. An analysis of structural elements makes it possible to study the compatibility of the system with external constraints (availability of natural resources and ecological services in spatial terms. The usefulness of the approach is illustrated in relation to an example of the use of charcoal in a rural village of Laos.

    Modern resource management faces trade-offs in the provision of various ecosystem goods and services to humanity. For fisheries management to develop into an ecosystem-based approach, the goal is not only to maximize economic profits, but to consider equally important conservation and social equity goals. We introduce such a triple-bottom line approach to the management of multi-species fisheries using the Baltic Sea as a case study. We apply a coupled ecological-economic optimization model to address the actual fisheries management challenge of trading-off the recovery of collapsed cod stocks versus the health of ecologically important forage fish populations. Management strategies based on profit maximization would rebuild the cod stock to high levels but may cause the risk of stock collapse for forage species with low market value, such as Baltic sprat (Fig. 1A). Economically efficient conservation efforts to protect sprat would be borne almost exclusively by the forage fishery as sprat fishing effort and profits would strongly be reduced. Unless compensation is paid, this would challenge equity between fishing sectors (Fig. 1B). Optimizing equity while respecting sprat biomass precautionary levels would reduce potential profits of the overall Baltic fishery, but may offer an acceptable balance between overall profits, species conservation and social equity (Fig. 1C). Our case study shows a practical example of how an ecosystem-based fisheries management will be able to offer society options to solve common conflicts between different resource uses. Adding equity considerations to the traditional trade-off between economy and ecology will greatly enhance credibility and hence compliance to management decisions, a further footstep towards healthy fish stocks and sustainable fisheries in the world ocean.

    Full Text Available As the 2005 Millennium Ecosystem Assessment revealed, many social-ecological systems around the world are currently being governed unsustainably. Consequently, social innovation is needed to transform current governance regimes and introduce new more resilient arrangements. Although dominant institutions and social groups may resist such innovations which threaten the status quo and their interests, groups on the margins of the established social order can often trigger governance transformations, despite a lack of conventional financial and institutional resources. In particular, there are numerous cases of marginalized groups initiating processes of radical change to establish sustainable governance practices for threatened social-ecological systems. We investigate one such case, and introduce a typology of power developed by Barnett and Duvall (2005 to illuminate the role that nongovernmental organizations and indigenous nations played in the transformation of a social-ecological governance regime for an area known as the Great Bear Rainforest, located in British Columbia, Canada. The analysis shows the interplay of compulsory, structural, institutional, and productive forms of power as the four key interest groups in this case enacted the governance transformation. The conclusions draw lessons about how the use and distribution of certain types of power can shape the course and outcomes of social-ecological governance transformations.

  10. Ecosystem Services are Social-ecological Services in a Traditional Pastoral System: the Case of California's Mediterranean Rangelands

    Directory of Open Access Journals (Sweden)

    Lynn Huntsinger

    2014-03-01

    Full Text Available When attempting to value ecosystem services and support their production, two critical aspects may be neglected. The term "ecosystem services" implies that they are a function of natural processes; yet, human interaction with the environment may be key to the production of many. This can contribute to a misconception that ecosystem service production depends on, or is enhanced by, the coercion or removal of human industry. Second, in programs designed to encourage ecosystem service production and maintenance, too often the inter-relationship of such services with social and ecological processes and drivers at multiple scales is ignored. Thinking of such services as "social-ecological services" can reinforce the importance of human culture, perspectives, and economies to the production of ecosystem services. Using a social-ecological systems perspective, we explore the integral role of human activity and decisions at pasture, ranch, and landscape scales. Just as it does for understanding ecosystems, a hierarchical, multiscaled framework facilitates exploring the complexity of social-ecological systems as producers of ecosystem services, to develop approaches for the conservation of such services. Using California's Mediterranean rangelands as a study area, we suggest that using a multiscaled approach that considers the importance of the differing drivers and processes at each scale and the interactions among scales, and that incorporates social-ecological systems concepts, may help avoid mistakes caused by narrow assumptions about "natural" systems, and a lack of understanding of the need for integrated, multiscaled conservation programs.

    Social participation in the health system constitutes one of the basic principles of Brazilian health sector reform. This paper analyses the concepts held by different groups of stakeholders with respect to social participation in health and identifies their opinions on hindering and enabling factors for this participation. A qualitative study was conducted using individual interviews (II) and focus groups (FG) with different groups of stakeholders: 135 users (II, GF), 14 community leaders (II, GF), 12 Municipal Health Council (MHC) members (II), 8 policymakers and (II) 37 health personnel (II, GF) were interviewed. A narrative content analysis of the results was conducted. Two municipalities in North-eastern Brazil, Cabo de Santo Agostinho and Camaragibe, made up the area of study. In all groups, a distinction between individual and group participation emerged and reached different levels of elaboration. Many informants' ideas described also their own ways of action. Individual participation concepts and the utilization of health services were predominant among users. Population and institutional factors were identified as obstacles to participation: users and community leaders referred both type of factors, while the health personnel and MHC members put more emphasis on the former. Some informants among the health personnel did not identify any barriers. Policymakers emphasised the lack of political will. The enabling factors mentioned reflected the same logic. Concepts and perceived hindering factors to participation which were described appear to show different ways of interaction among the diverse stakeholders and the health services. The results point towards a limited effect of the health policy on social participation. Elements that could contribute to an improvement are identified.

    Development policy increasingly focuses on building capacities to respond to change (adaptation), and to drive change (innovation). Few studies, however, focus specifically on the social and gender differentiation of capacities to adapt and innovate. We address this gap using a qualitative study in three communities in Solomon Islands; a developing country, where rural livelihoods and well-being are tightly tied to agriculture and fisheries. We find the five dimensions of capacity to adapt and to innovate (i.e. assets, flexibility, learning, social organisation, agency) to be mutually dependant. For example, limits to education, physical mobility and agency meant that women and youth, particularly, felt it was difficult to establish relations with external agencies to access technical support or new information important for innovating or adapting. Willingness to bear risk and to challenge social norms hindered both women's and men's capacity to innovate, albeit to differing degrees. Our findings are of value to those aspiring for equitable improvements to well-being within dynamic and diverse social-ecological systems.

    Suicidal behavior and its correlates remain relatively understudied in pregnant teenagers. A cross-sectional study with a consecutive sample of pregnant teenagers recipient of prenatal medical assistance by the national public health system in the urban area of Pelotas, southern Brazil. Sample size was estimated in 871 participants. Suicidal behavior and psychiatric disorders were assessed with the Mini International Neuropsychiatric Interview; the Abuse Assessment Screen was used to identify physical or sexual abuse; social support was assessed with the Medical Outcomes Survey Social Support Scale; a self-report questionnaire was used to collect socio-demographic, obstetric and other psychosocial data. Forty three (4.94%) teenagers refused to participate, resulting in 828 participants. Prevalence of suicidal behavior was 13.3%; lifetime suicide attempts were referred by 7.4%, with 1.3% reporting attempting suicide within the last month. After adjustment, we found significant associations of suicidal behavior with the 18-19 years old subgroup, low education, prior abortion, previous major depression, and physical abuse within the last 12 months. Pregnant teenagers with high social support showed prevalence ratios (PR) 67% lower (PR: 0.33; 95%CI: 0.19-0.56) than those with low social support. Furthermore, a wide range of psychiatric disorders, most notably major depressive disorder (PR: 2.75; 95%CI: 1.34-5.63) and panic disorder (PR: 6.36; 95%CI: 1.61-25.10), remained associated with suicidal behavior after adjustment. The cross-sectional design precludes causal inferences. We found that suicidal behavior is a relatively common feature in pregnant teenagers, frequently associated with psychiatric disorders.

    To determine the prevalence and duration of social security benefits (SSBs) claims to registered workers with asthma in Brazil by the Brazilian National Institute of Social Security in 2008. This was a retrospective, descriptive study, based on information obtained from the Brazilian Unified Benefit System database, on the number of SSB claims granted to registered workers with asthma in 2008. The reference population was the monthly mean number of workers registered in the Brazilian Social Registry Database in 2008. The variables studied were type of economic activity, gender, age, and type/duration of the SSB claim. The relationship between work and asthma was evaluated by the prevalence ratio (PR) between work-related and non-work-related SSB claims for asthma. In 2008, 2,483 SSB claims were granted for asthma, with a prevalence of 7.5 allowances per 100,000 registered workers. The prevalence was higher among females than among males (PR = 2.1 between the sexes). Workers > 40 years of age were 2.5 times more likely to be granted an SSB claim for asthma than were younger workers. The prevalence was highest among workers engaged in the following types of economic activity: sewage, wood and wood product manufacturing, and furniture manufacturing (78.8, 22.4, and 22.2 claims/100,000 registered workers, respectively). The median (interquartile range) duration of SSB claims for asthma was 49 (28-87) days. Asthma is a major cause of sick leave, and its etiology has a strong occupational component. This has a major impact on employers, employees, and the social security system. Being female, being > 40 years of age, and working in the areas of urban sanitation/sewage, wood and wood product manufacturing, and furniture manufacturing increase the chance of sick leave due to asthma.

    Policy for biodiversity conservation must evolve to cope with the increasing human footprint on natural systems. A major issue here is the need for policy for protected areas, which integrates their surrounding landscape and local human populations in the construction of socially grounded measures. To illustrate current conceptual thinking in this direction we present and provide a conceptual basis for a recent initiative in national park policy in France that is based on "ecological solidarity". In the light of other policy ideas and tools that have recently emerged for the co-construction of conservation policy, we argue that this concept provides an imaginative step towards consolidating ecological and social interdependence in biodiversity policy that goes beyond statutory park boundaries.

    The marine aquarium trade has played an important role in shaping the ecological state of coral reefs in Indonesia and much of the Asia-Pacific. The use of cyanide by ornamental fishers in Buleleng District, Bali, in the 1980s and 1990s has resulted in a precipitous decline in the ecological health of reefs. Cyanide-free harvesting techniques were introduced after 2000, along with reef restoration measures. This paper examines social and ecological processes in the fishing village of Les, Bal...

    Developing resource management strategies in the face of climate change is complicated by the considerable uncertainty associated with projections of climate and its impacts and by the complex interactions between social and ecological variables. The broad, interconnected nature of this challenge has resulted in calls for analytical frameworks that integrate research tools and can support natural resource management decision making in the face of uncertainty and complex interactions. We respond to this call by first reviewing three methods that have proven useful for climate change research, but whose application and development have been largely isolated: species distribution modeling, scenario planning, and simulation modeling. Species distribution models provide data-driven estimates of the future distributions of species of interest, but they face several limitations and their output alone is not sufficient to guide complex decisions for how best to manage resources given social and economic considerations along with dynamic and uncertain future conditions. Researchers and managers are increasingly exploring potential futures of social-ecological systems through scenario planning, but this process often lacks quantitative response modeling and validation procedures. Simulation models are well placed to provide added rigor to scenario planning because of their ability to reproduce complex system dynamics, but the scenarios and management options explored in simulations are often not developed by stakeholders, and there is not a clear consensus on how to include climate model outputs. We see these strengths and weaknesses as complementarities and offer an analytical framework for integrating these three tools. We then describe the ways in which this framework can help shift climate change research from useful to usable.

    Full Text Available The Galapagos Islands are among the most renowned natural sites in the world. Unlike other oceanic archipelagos, the ecological and evolutionary processes characteristic of Galapagos have been minimally affected by human activities, and the archipelago still retains most of its original, unique biodiversity. However, several recent reports suggest that the development model has turned unsustainable and that the unique values of the archipelago might be seriously at risk. In response to international concern, UNESCO added Galapagos to the list of World Heritage in Danger in 2007. Our goal was to provide new insights into the origins of the present-day crisis and suggest possible management alternatives. To this end, we re-examined the Galapagos situation from a broad systems perspective, conceptualizing the archipelago as a complex social-ecological system. Past, present, and possible future trends were explored using the resilience theory as a perspective for understanding the dynamics of the system. Four major historical periods were characterized and analyzed using Holling's adaptive cycle metaphor. The current Galapagos situation was characterized as a prolonged series of crisis events followed by renewal attempts that have not yet been completed. Three plausible future scenarios were identified, with tourism acting as the primary driver of change. The current tourism model reduces the system's resilience through its effects on the economy, population growth, resource consumption, invasive species arrival, and lifestyle of the island residents. Opportunities to reorganize and maintain a desirable state do exist. However, strong political and management decisions are urgently needed to avoid an irreversible shift to a socially and environmentally undesirable regime. Key measures to achieve a new sustainability paradigm for Galapagos include modifying traditional practices to produce a more adaptive resilience-based co-management model

    Full Text Available The aim of this study was to estimate the social cost of the leptospirosis cases that were attributed to the natural disaster of January 2011 in Nova Friburgo (State of Rio de Janeiro, Brazil through a partial economic assessment. This study utilized secondary data supplied by the Municipal Health Foundation of Nova Friburgo. Income scenarios based on the national and state minimum wages and on average income of the local population were employed. The total social cost of leptospirosis cases attributed to the 2011 disaster may range between US$21,500 and US$66,000 for the lower income scenario and between US$23,900 and US$100,800 for that of higher income. Empirical therapy represented a total avoided cost of US$14,800, in addition to a reduction in lethality. An estimated 31 deaths were avoided among confirmed cases of the disease, and no deaths resulted from the leptospirosis cases attributed to the natural disaster. There has been a significant post-disaster rise in leptospirosis incidence in the municipality, which illustrates the potential for increased cases—and hence costs—of this illness following natural disasters, which justifies the adoption of preventive measures in environmental health.

    2012-03-01

    Full Text Available This study explores and interprets relevant literature to construct a typology of benefit sharing arrangements for the governance of social-ecological systems in developing countries. The typology comprises three generic categories of benefit sharing arrangements: collaborative, market-oriented, and egalitarian. We contend that the three categories provide a useful basis for exploring and classifying the different societal arrangements required for governance of social-ecological systems. The typology we present is founded on a related set of explicit assumptions that can be used to explore and better understand the linkages among ecosystem services, benefit sharing, and governance. Issues that are strongly related to sustainability in developing countries form the core basis of our assumptions. Our aim is not to write a definitive exposition, but to spark debate and engage ongoing dialogue on governance and benefit sharing in the field of social-ecological systems.

    Full Text Available Agriculture in the mountain region of Rio de Janeiro State is characterized by intensive soil use and input. Such mountainous environments are vulnerable to climate events; thus, the current article presents a report on methods applied to exchange academic and traditional knowledge. The aim is to expand farmers’ perception about the need of implementing agro-ecological practices, mainly soil management practices, which are important for agricultural sustainability in mountainous environments. The study was conducted in a Nova Friburgo family production unit, in the mountain region of Rio de Janeiro State (Brazil. It consisted of implementing three observation and soil organic-matter management units. The idea was to reduce the incidence of clubroot of crucifers disease caused by Plasmidiophora brassicae. The soil fauna was discussed with local farmers, with emphasis on the association between ecological processes and soil management. The present study improved the discussion with farmers and the need of introducing other innovative conservation practices such as no-tillage system and participatory research based on agro-ecological propositions.

    Full Text Available Our study discusses how literature, in particular an autobiographical novel, can be approached as a valuable reservoir of social-ecological memory (SEM. Through our analysis of acclaimed Korean writer Park Wan-suh's autobiographical novel Who Ate Up All the Shinga?, we discuss how an individual (the author manifests ecoliteracy, place attachment, and identity in relation to Korea's traditional village landscape that can serve as a suitable setting for understanding Korea's local social-ecological contexts. We find a rich account of knowledge and practices related to living and ecological components, resource and landscape management systems, social institutions, and worldviews. The author's descriptions of her native village landscape show the role of village resource and landscape management practices in enhancing local biodiversity and developing ecoliteracy in relation to indigenous ecosystem-like concepts. In addition, several social capitals are mentioned as key to sustaining the village community. The author's knowledge of local plants is the result of her childhood experiences in nature, and her place attachment is tightly linked with her worldview that is cultivated through intricate human-nature relationships within the Korean traditional village landscape. Furthermore, the novel contributes to comprehending resilience thinking by providing a narrative of social changes and interactions between humans and nature. Thus, SEM retained in literature can facilitate a meaningful understanding of social-ecological contexts in a given social-ecological system. Our study therefore suggests new functions of autobiographical memory in literary work for delivering SEM, and informs the study of SEM across the fields of humanities, social sciences, and natural resources management.

  6. Regional syndromes: towards a dynamical classification of social-ecological sustainability challenges

    2015-04-01

    Schellnhuber et al (1997) first presented the concept of social-ecological syndromes as a means of mapping sustainability challenges facing modern regions to sets of sub-systems. They argued that the great diversity of global social-ecological systems could be represented as different combinations from a much smaller number of patterns of sub-systems. Here, we explore the possibility of extending this idea to an empirical and dynamical classification of system functioning, such as changes in the strength of connectivity, coupling between sub-systems and emergent phenomena. To demonstrate this approach we combine multi-decadal datasets for social, economic and biophysical changes from two contrasting regions in China. This allows us to reconstruct the evolution of system functioning in terms of regulating and provisioning ecosystem services. Climate records and political and policy time-lines provide insight about endogenous and exogenous drivers. Our findings show similar patterns in both regions of long-term trade-off between rising provisioning services and declining regulating services, but with important regional differences. In eastern China, the upward trajectory in provisioning services is strongly linked to the history of agricultural policy reforms but losses of regulating services are more an emergent phenomenon. In contrast, in southwest China, trajectories of provisioning and regulating services are both linked strongly to policy and development initiatives. In both regions, the last few years see the long term trade-off breaking down with provisioning services declining or remaining stationary while losses of regulating services continue to decline. Evidence exists in both regions that critical transitions have been crossed in some ecosystems. The strength of coupling between the socio-economic and biophysical sub-systems also remains strong and shows no sign of de-coupling in either region as required for sustainability. We discuss how our findings

    Social acceptance of smoking is associated with smoking prevalence. Higher smoking rates and ETS exposure might be considered as important indicators for pro-tobacco social norms or social climate. Among studies indicating the association between youth smoking and adult smoking behaviors, most were from individual-level study designs. An ecological study was conducted to determine the role of social climate, i.e., adult smoking behaviors and exposure to environmental tobacco smoke (ETS), on youth smoking behaviors. Data on the smoking behavior and ETS of 16,688 Taiwanese adults were collected in 2004 by telephone administration of the Taiwan Adult Smoking Survey. Similar data on 22,339 junior high school students were collected in 2004 by school-based administration of the Taiwan Youth Tobacco Survey. City/county-level data were analyzed across 25 counties by descriptive statistics, Pearson's correlation, and hierarchical multiple regression. In both adult and youth populations, overall or gender-specific smoking prevalence and ETS varied widely across counties/cities. The current youth smoking rate within counties was significantly positively correlated with the current adult smoking prevalence as well as home ETS exposure in adults or youth. For male youth, a 1% increase in the rate of home ETS exposure reported by youth increased the current male youth smoking rate by 0.20% after controlling the female youth smoking rate and home ETS exposure reported by adults (p=0.0197). For female youth, male youth smoking prevalence was the only variable that contributed significantly (Beta=0.46, psmoke-free environments by decreasing the social acceptability of smoking.

  8. Landscape, Environmental and Social Predictors of Hantavirus Risk in São Paulo, Brazil.

    Paula Ribeiro Prist

    Full Text Available Hantavirus Pulmonary Syndrome (HPS is a disease caused by Hantavirus, which are negative-sense RNA viruses in the family Bunyaviridae that are highly virulent to humans. Numerous factors modify risk of Hantavirus transmission and consequent HPS risk. Human-driven landscape change can foster transmission risk by increasing numbers of habitat generalist rodent species that serve as the principal reservoir host. Climate can also affect rodent population dynamics and Hantavirus survival, and a number of social factors can influence probability of HPS transmission to humans. Evaluating contributions of these factors to HPS risk may enable predictions of future outbreaks, and is critical to development of effective public health strategies. Here we rely on a Bayesian model to quantify associations between annual HPS incidence across the state of São Paulo, Brazil (1993-2012 and climate variables (annual precipitation, annual mean temperature, landscape structure metrics (proportion of native habitat cover, number of forest fragments, proportion of area planted with sugarcane, and social factors (number of men older than 14 years and Human Development Index. We built separate models for the main two biomes of the state (cerrado and Atlantic forest. In both biomes Hantavirus risk increased with proportion of land cultivated for sugarcane and HDI, but proportion of forest cover, annual mean temperature, and population at risk also showed positive relationships in the Atlantic forest. Our analysis provides the first evidence that social, landscape, and climate factors are associated with HPS incidence in the Neotropics. Our risk map can be used to support the adoption of preventive measures and optimize the allocation of resources to avoid disease propagation, especially in municipalities that show medium to high HPS risk (> 5% of risk, and aimed at sugarcane workers, minimizing the risk of future HPS outbreaks.

Using Stockols' social-ecological approach, we describe the role of various social (poverty, policy, stigma, culture, and migration and environmental determinants (the home environment, water resources development, and climate change in the perpetuation of helminthic diseases, as well as their impact as contextual factors on health promotion interventions through both the regular and community-based health systems. We examine these interactions in regard to community participation, intersectoral collaboration, gender, and possibilities for upscaling helminthic disease control and elimination programmes within the context of integrated and interdisciplinary approaches. The research agenda summarises major gaps that need to be addressed.

    Ornaments, weapons and aggressive behaviours may evolve in female animals by mate choice and intrasexual competition for mating opportunities-the standard forms of sexual selection in males. However, a growing body of evidence suggests that selection tends to operate in different ways in males and females, with female traits more often mediating competition for ecological resources, rather than mate acquisition. Two main solutions have been proposed to accommodate this disparity. One is to expand the concept of sexual selection to include all mechanisms related to fecundity; another is to adopt an alternative conceptual framework-the theory of social selection-in which sexual selection is one component of a more general form of selection resulting from all social interactions. In this study, we summarize the history of the debate about female ornaments and weapons, and discuss potential resolutions. We review the components of fitness driving ornamentation in a wide range of systems, and show that selection often falls outside the limits of traditional sexual selection theory, particularly in females. We conclude that the evolution of these traits in both sexes is best understood within the unifying framework of social selection.

    2010-12-01

    Full Text Available Farmers of the Nuosu Yi ethnic group in the Upper Baiwu watershed report reductions in the availability of local forest resources. A team of interdisciplinary scientists worked in partnership with this community to assess the type and extent of social-ecological change in the watershed and to identify key drivers of those changes. Here, we combine a framework for institutional analysis with resilience concepts to assess system dynamics and interactions among resource users, resources, and institutions over the past century. The current state of this system reflects a legacy of past responses to institutional disturbances initiated at the larger, national system scale. Beginning with the Communist Revolution in 1957 and continuing through the next two decades, centralized forest regulations imposed a mismatch between the scale of management and the scale of the ecological processes being managed. A newly implemented forest property rights policy is shifting greater control over the management of forest resources to individuals in rural communities. Collective forest users will be allowed to manage commodity forests for profit through the transfer of long-term leases to private contractors. Villagers are seeking guidance on how to develop sustainable and resilient forest management practices under the new policy, a responsibility returned to them after half a century and with less abundant and fewer natural resources, a larger and aggregated population, and greater influence from external forces. We assess the watershed's current state in light of the past and identify future opportunities to strengthen local institutions for governance of forest resources.

  13. The social ecology of resilience: addressing contextual and cultural ambiguity of a nascent construct.

    More than two decades after E. E. Werner and R. S. Smith (1982), N. Garmezy (1983), and M. Rutter (1987) published their research on protective mechanisms and processes that are most likely to foster resilience, ambiguity continues regarding how to define and operationalize positive development under adversity. This article argues that, because resilience occurs even when risk factors are plentiful, greater emphasis needs to be placed on the role social and physical ecologies play in positive developmental outcomes when individuals encounter significant amounts of stress. Four principles are presented as the basis for an ecological interpretation of the resilience construct: decentrality, complexity, atypicality, and cultural relativity. These 4 principles, and the research upon which they are based, inform a definition of resilience that emphasizes the environmental antecedents of positive growth. This framework can guide future theory development, research, and the design of interventions that promote well-being among populations who experience environments that inhibit resilience-promoting processes. © 2011 American Orthopsychiatric Association.

    From a social ecological perspective, this study examined the effects of stigma (societal level), trusting relationships with current caregivers (familial level), and self-esteem (individual level) on future orientation of children affected by HIV infection and AIDS. Comparing self-report data from 1221 children affected by parental HIV infection and AIDS and 404 unaffected children, affected children reported greater stigma and lower future orientation, trusting relationships, and self-esteem. Based on structural equation modeling, stigma experiences, trusting relationships, and self-esteem had direct effects on future orientation, with self-esteem and trusting relationships partially mediating the effect of stigma experiences on children's future orientation. Implications are discussed. © The Author(s) 2014.

    Currently, there is no standard method to assess the complex systems in rangeland ecosystems. Decision makers need baselines to create a common language of current rangeland conditions and standards for continued rangeland assessment. The Sustainable Rangeland Roundtable (SRR), a group of private and public organizations and agencies, has created a forum to discuss rangeland sustainability and assessment. The SRR has worked to integrate social, economic, and ecological disciplines related to rangelands and has identified a standard set of indicators that can be used to assess rangeland sustainability. As part of this process, SRR has developed a two-tiered conceptual framework from a systems perspective to study the validity of indicators and the relationships among them. The first tier categorizes rangeland characteristics into four states. The second tier defines processes affecting these states through time and space. The framework clearly shows that the processes affect and are affected by each other. ?? 2009 Taylor & Francis Group, LLC.

    2010-12-01

    Among rising rates of overweight and obesity, schools have become essential settings to promote health behaviors, such as physical activity (PA). As schools exist within a broader environment, the social ecological model (SEM) provided a framework to consider how different levels interact and influence PA. The purpose of this study was to provide insight on school-based PA promotion by investigating the integration between different levels of Emmons's SEM within one public school board in a large Canadian city. Interviews were conducted with participants from the government (n = 4), the public school board (n = 3), principals (n = 3), and teachers (n = 4) and analyzed to explore perspectives on the various levels of the model. The results suggested that higher level policies "trickled down" into the organizational level of the SEM but there was pivotal responsibility for schools to determine how to implement PA strategies. Furthermore, schools have difficulty implementing PA because of the continued priority of academic achievement.

    2004-06-01

    Full Text Available What makes social-ecological systems (SESs robust? In this paper, we look at the institutional configurations that affect the interactions among resources, resource users, public infrastructure providers, and public infrastructures. We propose a framework that helps identify potential vulnerabilities of SESs to disturbances. All the links between components of this framework can fail and thereby reduce the robustness of the system. We posit that the link between resource users and public infrastructure providers is a key variable affecting the robustness of SESs that has frequently been ignored in the past. We illustrate the problems caused by a disruption in this link. We then briefly describe the design principles originally developed for robust common-pool resource institutions, because they appear to be a good starting point for the development of design principles for more general SESs and do include the link between resource users and public infrastructure providers.

    2014-09-01

    Full Text Available We present a modeling framework that synthesizes social, economic, and ecological aspects of landscape change to evaluate how different agricultural policy and land tenure scenarios and land management preferences affect landscape pattern and downstream water quality. We linked a stylized agent-based model (ABM of farmers' conservation practice adoption decisions with a water quality model, the Soil and Water Assessment Tool (SWAT, to simulate the water quality effects of changing land tenure dynamics and different policies for crop revenue insurance in lieu of commodity payments over 41 years (1970-2010 for a predominantly agricultural watershed of Lake Erie. Results show that non-operator owner involvement in land management decisions yields the highest reduction in sediment and nutrient loads, and crop revenue insurance leads to more homogeneous farmer decisions and a slight increase in sediment and nutrient loads unless cross compliance with expanded conservation requirements is implemented.

    2015-09-01

    Full Text Available River basin modeling under complexity requires analytical frameworks capable of dealing with the multiple scales and dimensions of environmental problems as well as uncertainty in the evolution of social systems. Conceptual and methodological developments can now be framed using the wide socio-eco-hydrological approach. We add hierarchy theory into the mix to discuss the conceptualization of river basins as complex, holarchic social-ecological systems. We operationalize the social-ecological systems water metabolism framework in a semiarid watershed in Spain, and add the governance dimension that shapes human-environment reciprocity. To this purpose, we integrate an eco-hydrological model with the societal metabolism accounting scheme for land use, human activity, and water use. We explore four types of interactions: between societal organization and water uses/demands, between ecosystem organization and their water requirements/supplies, between societal metabolism and aquatic ecosystem health, and between water demand and availability. Our results reveal a metabolic pattern of a high mountain rural system striving to face exodus and agricultural land abandonment with a multifunctional economy. Centuries of social-ecological evolution shaping waterscapes through traditional water management practices have influenced the eco-hydrological functioning of the basin, enabling adaptation to aridity. We found a marked spatial gradient on water supply, use pattern, and impact on water bodies from the head to the mouth of the basin. Management challenges posed by the European water regulatory framework as a new driver of social-ecological change are highlighted.

    Full Text Available Aquatic ecosystems have often been significantly altered by multiple impacts. The Guapiaçu-Macacu Hydrographic Complex is an important basin in Rio de Janeiro characterized by distinct ecological zones that make up an Ecological Economic Zoning. This research evaluated ecological upright in segments of this Complex located in Wildlife Conservation Zone (WCZ and the Agricultural Use Zone (AUZ using the Protocol Visual Assessment (PVA and physical, chemicals and microbiology methods. The results showed a significant difference between the points of lowest contamination degree in WCZ and stretches with a greater impact degree in AUZ. The PVA was more sensible than the conventional parameters in the resolution between segments impacted environmentally and impacted middle located in AUZ. This type of evaluation proved to be more effective in environmental monitoring the water quality for watersheds that have their Ecological Economic Zoning Plan. Therefore, the use of physical, chemical and microbiological methods must be complemented by the PVA.

    Full Text Available This paper discusses opportunities for alternative collaborative approaches for social-ecological research in general and, in this context, for modeling land-use/land-cover change. In this field, the rate of progress in academic research is steady but perhaps not as rapid or efficient as might be possible with alternative organizational frameworks. The convergence of four phenomena provides new opportunities for cross-organizational collaboration: (1 collaborative principles related to "open source" (OS software development, (2 the emerging area of "open content" (OC licensing, (3 the World Wide Web as a platform for scientific communication, and (4 the traditional concept of peer review. Although private individuals, government organizations, and even companies have shown interest in the OS paradigm as an alternative model for software development, it is less commonly recognized that this collaborative framework is a potential innovation of much greater proportions. In fact, it can guide the collective development of any intellectual content, not just software. This paper has two purposes. First, we describe OS and OC licensing, dispense with some myths about OS, and relate these structures to traditional scientific process. Second, we outline how these ideas can be applied in an area of collaborative research relevant to the study of social-ecological systems. It is important to recognize that the concept of OS is not new, but the idea of borrowing OS principles and using OC licensing for broader scientific collaboration is new. Over the last year, we have been trying to initiate such an OS/OC collaboration in the context of modeling land use and land cover. In doing so, we have identified some key issues that need to be considered, including project initiation, incentives of project participants, collaborative infrastructure, institutional design and governance, and project finance. OS/OC licensing is not a universal solution suitable for all

    Full Text Available The dynamics of land-use transitions decrease the coastal resilience of the social-ecological landscape (SEL, particularly in light of the fact that it is necessary to analyze the causal relationship between the two systems because operations of the social system and the ecological system are correlated. The purpose of this study is to analyze the dynamics of the coastal SEL and create a sustainable land-use planning (SLUP strategy to enhance coastal resilience. The selected study site was Shindu-ri, South Korea, where land-use transitions are increasing and coastal resilience is therefore decreasing. Systems thinking was used to analyze the study, which was performed in four steps. First, the issues affecting the coastal area in Shindu-ri were defined as coastal landscape management, the agricultural structure, and the tourism industry structure. Second, the main variables for each issue were defined, and causal relationships between the main variables were created. Third, a holistic causal loop diagram was built based on both dynamic thinking and causal thinking. Fourth, five land-uses, including those of the coastal forest, the coastal grassland, the coastal dune, the agricultural area, and developed sites, were selected as leverage points for developing SLUP strategies to increase coastal resilience. The results show that “decrease in the size of the coastal forest”, “decrease in the size of the coastal dune”, and “increase in the size of the coastal grasslands” were considered parts of a land-use plan to enhance the resilience of the Shindu-ri SEL. This study developed integrated coastal land-use planning strategies that may provide effective solutions for complex and dynamic issues in the coastal SEL. Additionally, the results may be utilized as basic data to build and implement coastal land-use planning strategies.

    Although there is acknowledgment that the complexity of social-ecological systems governance demands representation from diverse perspectives, there is little agreement in the literature on how to cross both fiat (human-demarcated) and bona fide (physical) boundaries to address such complexities. As a cohort of interdisciplinary scholars, we navigate the boundary between science and practice to address the question of fit regarding the role of organizations in transcending boundaries. We found there is a need to rectify discrepancies between theories about boundaries and theories about organizations. To this end, we propose a conceptual framework to analyze transboundary organizations, an umbrella term to group the literature on boundary organizations, intermediaries and bridging organizations; we introduce this term to illustrate they are not mutually exclusive and to facilitate interdisciplinary research. We first examine social-ecological systems (SES), a framework intended to improve understandings of boundaries and governance. We then continue to unpack the complexity of boundaries and organizations, specifically through important transboundary concepts such as scale and organizational learning. This helps frame our examination of the literature on: 1) boundary organizations; 2) bridging organizations (third-party entities); and 3) intermediaries (distinguished by their position between other actors). Our review identifies a number of discrepancies that pertain to the types of boundaries discussed and the roles assigned to organizations governing SES. Important characteristics have emerged from our review of transboundary organizations including legitimacy, saliency, urgency, and credibility. In developing a conceptual framework, we argue that transboundary organizations: 1) expand upon the boundary spectrum, 2) incorporate transboundary concepts, and 3) hybridize characteristics of boundary, bridging, and intermediary organizations. We conclude with a number

    Protected areas are considered vital for the conservation of biodiversity. Given their central role in many conservation strategies, it is important to know whether they adequately protect biodiversity within their boundaries; whether they are becoming more isolated from other natural areas over time; and whether they play a role in facilitating or reducing land-cover change in their surroundings. We used matching methods and national and local analyses of land-cover change to evaluate the combined effectiveness (i.e., avoided natural-cover loss), isolation (i.e., changes in adjacent areas), and spillover effects (i.e., impacts on adjacent areas) of 19 national parks in South Africa from 2000 to 2009. All parks had either similar or lower rates of natural-cover loss than matched control samples. On a national level, mean net loss of natural cover and mean net gain of cultivation cover decreased with distance from park boundary, but there was considerable variation in trends around individual parks, providing evidence for both increased isolation and buffering of protected areas. Fourteen parks had significant positive spillover and reduced natural-cover loss in their surroundings, whereas five parks experienced elevated levels of natural-cover loss. Conclusions about social-ecological spillover effects from protected areas depended heavily on the measures of land-cover change used and the scale at which the results were aggregated. Our findings emphasize the need for high-resolution data when assessing spatially explicit phenomena such as land-cover change and challenge the usefulness of large-scale (coarse grain, broad extent) studies for understanding social-ecological dynamics around protected areas. © 2016 Society for Conservation Biology.

    Full Text Available In Latin America, indigenous communities have been distinguished by continuous marginalization and degradation of their social-ecological systems (SES, and this is the case of San Nicolás Zoyatlan (Guerrero, Mexico. With the purpose of establishing restoration strategies, we conducted an in situ diagnosis to assess the current condition of the community and its disturbance factors. We combined methods of environmental and social sciences to analyze, in diachronic and synchronic contexts, how the SES’s natural resources are used. Results indicate that the chronic ecological disturbance of the SES and agrarian conflicts have contributed to the degradation of vegetation and soil. Thus, vegetation is impoverished, with secondary tropical deciduous forest (TDF shrub vegetation predominating, and the risk of soil degradation is high, despite the inhabitants’ knowledge and appreciation of this resource. To reverse degradation, we defined and established rehabilitation practices with the involvement of inhabitants. These comprised agroforestry systems (AFSs and plantations (PLs on community lands, using 18 native TDF species selected on the basis of local preferences. Our ongoing assessment indicates that after more than a decade, the AFSs and PLs are maintained and managed by the people, as reflected in the current size of plants whose inputs contribute to improve physical and chemical soil characteristics, such as soil aggregate formation, cation exchange capacity and organic matter content. However, we concluded that we need to confirm whether the ecosystem processes and environmental services are recovered and maintained over time, in addition to determining how they have influenced and will continue to influence the socioeconomic factors involved in maintaining rehabilitation practices.

    The environmental determinants of public health and social equity present many challenges to a sustainable urbanism-climate change, water shortages and oil dependency to name a few. There are many pathways from urban environments to human health. Numerous links have been described but some underlying mechanisms behind these relationships are less understood. Combining theory and methods is a way of understanding and explaining how the underlying structures of urban environments relate to public health and social equity. This paper proposes a model for an ecological public health, which can be used to explore these relationships. Four principles of an ecological public health-conviviality, equity, sustainability and global responsibility-are used to derive theoretical concepts that can inform ecological public health thinking, which, among other things, provides a way of exploring the underlying mechanisms that link urban environments to public health and social equity. Theories of more-than-human agency inform ways of living together (conviviality) in urban areas. Political ecology links the equity concerns about environmental and social justice. Resilience thinking offers a better way of coming to grips with sustainability. Integrating ecological ethics into public health considers the global consequences of local urban living and thus attends to global responsibility. This way of looking at the relationships between urban environments, public health and social equity answers the call to craft an ecological public health for the twenty-first century by re-imagining public health in a way that acknowledges humans as part of the ecosystem, not separate from it, though not central to it. © The Author (2013).

    Full Text Available According to the U.S. National Environmental Policy Act of 1969 (NEPA, federal action to manipulate habitat for species conservation requires an environmental impact statement, which should integrate natural, physical, economic, and social sciences in planning and decision making. Nonetheless, most impact assessments focus disproportionately on physical or ecological impacts rather than integrating ecological and socioeconomic components. We developed a participatory social-ecological impact assessment (SEIA that addresses the requirements of NEPA and integrates social and ecological concepts for impact assessments. We cooperated with the Bureau of Land Management in Idaho, USA on a project designed to restore habitat for the Greater Sage-Grouse (Centrocercus urophasianus. We employed questionnaires, workshop dialogue, and participatory mapping exercises with stakeholders to identify potential environmental changes and subsequent impacts expected to result from the removal of western juniper (Juniperus occidentalis. Via questionnaires and workshop dialogue, stakeholders identified 46 environmental changes and associated positive or negative impacts to people and communities in Owyhee County, Idaho. Results of the participatory mapping exercises showed that the spatial distribution of social, economic, and ecological values throughout Owyhee County are highly associated with the two main watersheds, wilderness areas, and the historic town of Silver City. Altogether, the SEIA process revealed that perceptions of project scale varied among participants, highlighting the need for specificity about spatial and temporal scales. Overall, the SEIA generated substantial information concerning potential impacts associated with habitat treatments for Greater Sage-Grouse. The SEIA is transferable to other land management and conservation contexts because it supports holistic understanding and framing of connections between humans and ecosystems. By applying

    Human kind has always been curios and motivated to understand and quantify environmental processes in order to predict and anticipate the evolution of vital ecosystem services. Even the very first civilizations used empirical correlations to predict outcomes of rains and subsequent harvest efficiencies. Along with the insights into the functioning of ecosystems, humans also became aware that their anthropogenic activities can have positive and negative impact on ecosystem services. In recent years, geosciences have brought forward new sophisticated observations and modeling tools, with the aim to improve predictions of ecological developments. At the same time, the added value of linking ecological factors to the surrounding social structure has received a growing acceptance among scientists. A social-ecological system approach brings in a holistic understanding of how these systems are inevitably interlinked and how their sustainability can be better maintained. We claim that the biggest challenge for geoscience in the coming decades will be to link these two disciplines in order to establish adequate strategies to preserve natural ecosystems and their services, parallel to their utilization. We will present various case studies from more than a decade of research, ranging from water quality in mountain lakes, climate change impacts on water availability and declining fishing yields in freshwaters and discuss how the studies outcomes could be given added value by interpreting them via social-ecological system analysis. For instance, sophisticated field investigations revealed that deep water mixing in lake Issyk-Kul, Kirgizstan, is intensively distributing pollutants in the entire lake. Although fishery is an important sector in the region, the local awareness of the importance of water quality is low. In Switzerland, strict water protection laws led to ologotrophication of alpine lakes, reducing fishing yields. While local fishermen argued that local fishery is

    Full Text Available The most lasting legacy of the Soviet experience, more so than institutions that persist in the Russian Federation today or the mentalities of citizens of post-Soviet states, was its transformation of Eurasia from a rural continent into an urban one. Particularly after the Great Patriotic War, the landscape of Soviet urban spaces changed as countless rows of low-quality apartment housing sprung up and a uniform socialist urban culture appeared to be forming. However, how and why this urban revolution happened, and what effect it had on the psychological makeup of Soviet citizens, remains lesser known. Meanwhile, while scholars of urban history such as Jane Jacobs, Reyner Banham, Lewis Mumford, and Mike Davis have produced fascinating tracts and monographs on the “ecologies” of American urban spaces – how, in other words, human beings in various political systems have interacted with the built urban landscape around them – limited work has been done on similar processes and histories in the Soviet world beyond the technical literature of the Cold War era. In this paper, I attempt to provide the outlines of such a history with such an approach by analyzing how changes in the Soviet urban fabric from approximately 1932 to 1980s affected social life in Soviet cities and among Soviet families. Basing my argument on close readings of Soviet books on gradostroitel'stvo (urban construction, urban studies as well as literature, and guided by the insights of the above-listed urbanist thinkers, I argue that changes in urban planning so altered the relationship between citizens, the Party, and History that the Soviet system lost key strengths that had emboldened it during the 1930s and 1940s. In particular, while new Soviet housing projects obviously raised the standard of living of a great portion of the population, in resolving the housing problem, they also dismantled the “strang
