  4. Evolution of Sustainability in American Forest Resource Management Planning in the Context of the American Forest Management Textbook

    Directory of Open Access Journals (Sweden)

    Thomas J. Straka


    Full Text Available American forest resource management and planning goes back to the European roots of American Forestry. Timber management plans, documents based on forest regulation for timber production, were the foundation of American forestry. These types of management plans predominated until World War II. Multiple use forestry developed after World War II and issues like recreation, wildlife, water quality, and wilderness became more important. In the 1970’s harvest scheduling became part of the planning process, allowing for optimization of multiple goals. By 2001 social, environmental, and economic goals were integrated into the timber production process. American forestry experienced distinct historical periods of resource planning, ranging from classic sustained yield timber production, to multiple use-sustained yield, to sustainable human-forest systems. This article traces the historical changes in forest management planning philosophy using the forest management textbooks of the time. These textbooks provide insight into the thought process of the forestry profession as changes in the concept of sustainability occurred.

  5. Landscape development, forest fires, and wilderness management. (United States)

    Wright, H E


    ' grand scheme of vegetational climax-created soon after Davis's model of landform development-can be evaluated in terms of modern knowledge. Disillusion with the climax model paralleled disillusion with Davis's model in the 1950's, but the climax model can be tested, because the record of vegetational history is accessible, datable, and decipherable. In the short term of a few decades, successional vegetation stages occur in variety of situations, as confirmed by observation or by techniques such as tree-ring analysis. The successional vegetation stages are reactions to nutrients, weather, competition, and consumption. Such succession implies long-term disequilibrium, or at least unidirectional development. The long-term controlling factor in Clements' model of vegetation development is climate. With climatic stability the succession will proceed to a climax. In the Appalachian Mountains, geomorphic, microclimatic, and edaphic conditions limit climax development, producing a polyclimax, which is generally sustained by the dominance of these factors. Death and regeneration of single forest trees is controlled mostly by windstorms. The distributional pattern may be locally transected by lightning fires, major windstorms, or washouts. However, the long-term stability of Appalachian forests is demonstrated by pollen stratigraphy. Although we can infer the long-term stability of Appalachian forests, the trends and mechanics of short-term vegetational succession are not fully understood, because lack of sizable areas of virgin forest limits investigations of natural conditions. In this respect, the eastern United States is already much like western Europe, where climatic and disturbance factors in vegetational history cannot be disentangled. In the Great Lakes region, a large area of virgin forest exists in the BWCA of northeastern Minnesota. Here short- and long-term studies show that for at least 9000 years the principal stabilizing factor has been the frequent occurrence of

  14. Interpreting Sustainability for Urban Forests

    Directory of Open Access Journals (Sweden)

    Camilo Ordóñez


    Full Text Available Incisive interpretations of urban-forest sustainability are important in furthering our understanding of how to sustain the myriad values associated with urban forests. Our analysis of earlier interpretations reveals conceptual gaps. These interpretations are attached to restrictive definitions of a sustainable urban forest and limited to a rather mechanical view of maintaining the biophysical structure of trees. The probing of three conceptual domains (urban forest concepts, sustainable development, and sustainable forest management leads to a broader interpretation of urban-forest sustainability as the process of sustaining urban forest values through time and across space. We propose that values—and not services, benefits, functions or goods—is a superior concept to refer to what is to be sustained in and by an urban forest.

  15. Geochemical survey maps of the wildernesses and roadless areas in the White Mountains National Forest, Coos, Grafton, and Carroll counties, New Hampshire (United States)

    Canney, F.C.; Howd, F.H.; Domenico, J.A.; Nakagawa, H.M.


    The Wilderness Act (Public Law 88-577, September 3, 1964) and related acts require the U.S. Geological Survey and the U.S. Bureau of Mines to survey certain areas on Federal lands to determine what mineral values, if any, may be present. Results must be made available to the public and be submitted to the President and the Congress. This report presents the results a geochemical survey of the Great Gulf and Presidential Range-Dry River Wilderness Areas; the Dartmouth Range, Wild River, Pemigewasset, Kinsman Mountain, Mount Wolf-Gordon Pond, Jobildunk, Carr Mountain, Sandwich Range, and the Dry River Extention (2 parcels) Roadless Areas; and the intervening and immediately surrounding areas in the White Mountain National Forest, Coos, Grafton, and Carroll Counties, New Hampshire. The Great Gulf Wilderness was established when the Wilderness Act was passed in 1964, and the Presidential Range-Dray Wiver Wilderness was established by Public Law 93-622, January 3, 1975. The Dartmouth Range, Wild River, Pemigewasset, Kinsman Mountain, Mount Wolf-Gordon Pond, Carr Mountain, and Jobildunk areas were classified as a further planning area during the Second Roadless Area Review and Evaluation (RARE II) by the U.S. Forest Service, January 1979.

  19. Perspectives from the Aldo Leopold Wilderness Research Institute: Amphibians and wilderness (United States)

    Corn, Paul Stephen


    The decline of amphibian species has emerged as a major global conservation issue in the last decade. Last year, the Department of the Interior (DOI) initiated a major national initiative to detect trends in amphibian populations and research the causes of declines. The program, conducted principally by the U.S. Geological Survey (USGS), emphasizes lands managed by DOI, but collaboration with the Forest Service is encouraged to increase the scope of inference about population trends. Although amphibians are not usually the first group of animals that comes to mind when one thinks of wilderness, conservation of amphibian populations is clearly a wilderness issue.

  5. Does participatory forest management promote sustainable forest utilisation in Tanzania?

    DEFF Research Database (Denmark)

    Treue, Thorsten; Ngaga, Y.M.; Meilby, Henrik


    Over the past 20 years, Participatory Forest Management (PFM) has become a dominant forest management strategy in Tanzania, covering more than 4.1 million hectares. Sustainable forest use and supply of wood products to local people are major aims of PFM. This paper assesses the sustainability...... of forest utilisation under PFM, using estimates of forest condition and extraction rates based on forest inventories and 480 household surveys from 12 forests; seven under Community Based Forest Management (CBFM), three under Joint Forest Management (JFM) and two under government management (non......-PFM). Extraction of products is intense in forests close to Dar es Salaam, regardless of management regime. Further from Dar es Salaam, harvesting levels in forests under PFM are, with one prominent exception, broadly sustainable. Using GIS data from 116 wards, it is shown that half of the PFM forests in Tanzania...

  9. Making Forest Values Work: Enhancing Multi-Dimensional Perspectives towards Sustainable Forest Management

    Directory of Open Access Journals (Sweden)

    Doni Blagojević


    Full Text Available Background and Purpose: Sustainability, sustainable development and sustainable forest management are terms that are commonly, and interchangeably used in the forest industry, however their meaning take on different connotations, relative to varying subject matter. The aim of this paper is to look at these terms in a more comprehensive way, relative to the current ideology of sustainability in forestry. Materials and Methods: This paper applies a literature review of the concepts of: i sustainable development; ii sustainable forest management; and iii economic and non-economic valuation. The concepts are viewed through a historical dimension of shifting paradigms, originating from production- to service-based forestry. Values are discussed through a review of general value theory and spatial, cultural and temporal differences in valuation. Along the evolution of these concepts, we discuss their applicability as frameworks to develop operational guidelines for forest management, relative to the multi-functionality of forests. Results and Conclusions: Potential discrepancies between the conceptual origins of sustainable development and sustainable forest management are highlighted, relative to how they have been interpreted and diffused as new perceptions on forest value for the human society. We infer the current paradigm may not reflect the various dimensions adequately as its implementation is likely to be more related to the distribution of power between stakeholders, rather than the value stakeholders’ place on the various forest attributes.

  10. Comparing Sustainable Forest Management Certifications Standards: A Meta-analysis

    Directory of Open Access Journals (Sweden)

    Michael Rawson. Clark


    Full Text Available To solve problems caused by conventional forest management, forest certification has emerged as a driver of sustainable forest management. Several sustainable forest management certification systems exist, including the Forest Stewardship Council and those endorsed by the Programme for the Endorsement of Forest Certification, such as the Canadian Standards Association - Sustainable Forestry Management Standard CAN/CSA - Z809 and Sustainable Forestry Initiative. For consumers to use certified products to meet their own sustainability goals, they must have an understanding of the effectiveness of different certification systems. To understand the relative performance of three systems, we determined: (1 the criteria used to compare the Forest Stewardship Council, Canadian Standards Association - Sustainable Forestry Management, and Sustainable Forestry Initiative, (2 if consensus exists regarding their ability to achieve sustainability goals, and (3 what research gaps must be filled to improve our understanding of how forest certification systems affect sustainable forest management. We conducted a qualitative meta-analysis of 26 grey literature references (books, industry and nongovernmental organization publications and 9 primary literature references (articles in peer-reviewed academic journals that compared at least two of the aforementioned certification systems. The Forest Stewardship Council was the highest performer for ecological health and social sustainable forest management criteria. The Canadian Standards Association - Sustainable Forestry Management and Sustainable Forestry Initiative performed best under sustainable forest management criteria of forest productivity and economic longevity of a firm. Sixty-two percent of analyses were comparisons of the wording of certification system principles or criteria; 34% were surveys of foresters or consumers. An important caveat to these results is that only one comparison was based on

  14. Social-value maps for Arapaho, Roosevelt, Medicine Bow, Routt, and White River National Forests, Colorado and Wyoming (United States)

    Ancona, Zachary H.; Semmens, Darius J.; Sherrouse, Benson C.


    Executive SummaryThe continued pressures of population growth on the life-sustaining, economic, and cultural ecosystem services provided by our national forests, particularly those located near rapidly growing urban areas, present ongoing challenges to forest managers. Achieving an effective assessment of these ecosystem services includes a proper accounting of the ecological, economic, and social values attributable to them. However, assessments of ecosystem goods and services notably lack information describing the spatial distribution and relative intensity of social values—the perceived, nonmarket values derived particularly from cultural ecosystem services. A geographic information system (GIS) tool developed to fill this need, Social Values for Ecosystem Services (SolVES;, now provides the capability to generate social-value maps at a range of spatial scales. This report presents some of the methods behind SolVES, procedures needed to apply the tool, the first formal map products resulting from its application at a regional scale, and a discussion of the management implications associated with this type of information.In this study, we use SolVES to identify the location and relative intensity of social values as derived from survey responses gathered from residents living in counties adjacent to Arapaho, Roosevelt, Medicine Bow, Routt, and White River National Forests. The results, presented as a series of social-value maps, represent the first publicly available spatial data on social-value intensity for the southern Rocky Mountain region. Our analysis identified high-value areas for social values including aesthetic, biodiversity, and life sustaining within wilderness areas. Other values, like recreation, show high-value areas both within wilderness and throughout the general forest areas, which can be attributed to people using the forests for a diverse set of recreational activities. The economic social-value type was lower

  1. The Contribution of Forests and Trees to Sustainable Diets

    Directory of Open Access Journals (Sweden)

    Danny Hunter


    Full Text Available With the growing demands from a population expected to reach 9 billion people by 2050, it is unclear how our current global food system will meet future food needs. Ensuring that all people have access to adequate and nutritious food produced in an environmentally and socio-culturally sustainable manner is one of the greatest challenges of our time. “Sustainable diets” have been proposed as a multidimensional framework to address the need for nutritious and adequate food in the context of the many challenges facing the world today: reducing poverty and hunger, improving environmental health, enhancing human well-being and health, and strengthening local food networks, sustainable livelihoods and cultural heritage. This paper examines the contribution of forests and trees to sustainable diets, covering among others, nutritional, cultural, environmental and provisioning aspects. The literature reviewed highlight major opportunities to strengthen the contribution of forest and tree foods to sustainable diets. However, several constraints need to be removed. They relate to: cultural aspects, sustainable use of non-wood forest products, organization of forest food provisioning, limited knowledge of forest food composition, challenges in adapting management of forests and trees to account for forest foods, and in integrating forest biodiversity into complex landscapes managed for multiple benefits. Finally, the paper identifies research gaps and makes recommendations to enhance the contribution of forest foods to sustainable diets through increased awareness and better integration of information and knowledge on nutritious forest foods into national nutrition strategies and programs.

  3. Sustainability assessment in forest management based on individual preferences. (United States)

    Martín-Fernández, Susana; Martinez-Falero, Eugenio


    This paper presents a methodology to elicit the preferences of any individual in the assessment of sustainable forest management at the stand level. The elicitation procedure was based on the comparison of the sustainability of pairs of forest locations. A sustainability map of the whole territory was obtained according to the individual's preferences. Three forest sustainability indicators were pre-calculated for each point in a study area in a Scots pine forest in the National Park of Sierra de Guadarrama in the Madrid Region in Spain to obtain the best management plan with the sustainability map. We followed a participatory process involving fifty people to assess the sustainability of the forest management and the methodology. The results highlighted the demand for conservative forest management, the usefulness of the methodology for managers, and the importance and necessity of incorporating stakeholders into forestry decision-making processes.

  6. Research plan for integrated ecosystem and pollutant monitoring at remote wilderness study sites

    International Nuclear Information System (INIS)

    Bruns, D.A.; Wiersma, G.B.


    This research plan outlines an approach to the measurement of pollutants and ecosystem parameters at remote, high-elevation, wilderness study sites. A multimedia, systems approach to environmental monitoring is emphasized. The primary purpose of the research is to apply and field test a technical report entitled ''Guidelines for measuring the physical, chemical, and biological condition of wilderness ecosystems.'' This document intended to provide Federal Land Managers with information to establish environmental monitoring programs in wilderness areas. To date, this monitoring document has yet to be evaluated under rigorous field conditions at a remote, high-elevation Rocky Mountain site. For the purpose of field testing approaches to monitoring of pollutants and ecosystems in remote, wilderness areas, evaluation criteria were developed. These include useability, cost-effectiveness, data variability, alternative approaches, ecosystems conceptual approach, and quality assurance. Both the Forest Service and INEL environmental monitoring techniques will be evaluated with these criteria. Another objective of this research plan is to obtain an integrated data base on pollutants and ecosystem structure and function at a remote study site. The methods tested in this project will be used to acquire these data from a systems approach. This includes multimedia monitoring of air and water quality, soils, and forest, stream, and lake ecosystems. 71 refs., 1 fig., 9 tabs

    The cultural roots and images of the Finnish wilderness lie in its use as a source of livelihood practiced in southern and central Finland during the Middle Ages. There are statutory wilderness areas in Finland, but Finnish people consider many other areas as wilderness. It is important for management of the areas, statutory wilderness areas and the other wilderness-...

  9. Wilderness management dilemmas: fertile ground for wilderness management research (United States)

    David N. Cole; William E. Hammitt


    Increasingly, wilderness managers must choose between the objective of wildness (“untrammeled” wilderness) and the objectives of naturalness and solitude. This dilemma has surfaced with awareness of the pervasiveness of human influence in wilderness and that regulation is often the only way to maintain outstanding opportunities for solitude. Should we trammel...

  10. Sustainable Forest Management in Cameroon Needs More than Approved Forest Management Plans

    Directory of Open Access Journals (Sweden)

    Paolo Omar. Cerutti


    Full Text Available One of the main objectives of the 1994 Cameroonian forestry law is to improve the management of production forests by including minimum safeguards for sustainability into compulsory forest management plans. As of 2007, about 3.5 million hectares (60% of the productive forests are harvested following the prescriptions of 49 approved management plans. The development and implementation of these forest management plans has been interpreted by several international organizations as long awaited evidence that sustainable management is applied to production forests in Cameroon. Recent reviews of some plans have concluded, however, that their quality was inadequate. This paper aims at taking these few analyses further by assessing the actual impacts that approved management plans have had on sustainability and harvesting of commercial species. We carry out an assessment of the legal framework, highlighting a fundamental flaw, and a thorough comparison between data from approved management plans and timber production data. Contrary to the principles adhered to by the 1994 law, we find that the government has not yet succeeded in implementing effective minimum sustainability safeguards and that, in 2006, 68% of the timber production was still carried out as though no improved management rules were in place. The existence of a number of approved management plans cannot be used a proxy for proof of improved forest management.

  13. Sustainable use of forest and hunting resources

    Directory of Open Access Journals (Sweden)

    Danilović Milorad


    Full Text Available This paper presents the issue of the use of forest and hunting resources in Serbia, with special emphasis on their sustainability. The use of modern technological solutions in terms of sustainable use of forest and hunting resources should be seen through an analysis and evaluation of environmental impacts. The existing machinery used in Serbian forestry cannot respond to the current demands of forestry production. However, the current unfavourable conditions can be significantly improved with appropriate measures. The planning of a network of roads including a number of factors that directly and indirectly affect sustainable use is of great importance for the development of forestry and hunting. Wood biomass in Serbian forests should be used in the manner and to the extent that ensures the sustainability of ecosystems and the production of large quantities of energy. In recent years, non-timber forest products have gained importance, so that the income generated from their use is growing. The impact of newly adopted laws and bylaws in the field of forestry, hunting and the protection of nature and environment will depend primarily on their application, control, execution and possible amendments and adjustments.

    Mark Fincher


    Wilderness managers are faced with making judgments about the appropriateness of different types of recreational activities. One of the criteria they use is wilderness dependence-the notion that an activity should be allowed, or privileged if rationing is required, if it depends on a wilderness setting for much of its value. Inherent in this concept is the idea that...

  16. Urban forests for sustainable urban development (United States)

    Sundara, Denny M.; Hartono, Djoko M.; Suganda, Emirhadi; Haeruman, S. Herman J.


    This paper explores the development of the urban forest in East Jakarta. By 2030 Jakarta area has a target of 30% green area covering 19,845 hectares, including urban forest covering an area of 4,631 hectares. In 2015, the city forest is only 646 hectares, while the city requires 3,985 hectares of new land Urban forest growth from year to year showed a marked decrease with increasing land area awoke to commercial functions, environmental conditions encourage the development of the city to become unsustainable. This research aims to support sustainable urban development and ecological balance through the revitalization of green areas and urban development. Analytical methods for urban forest area is calculated based on the amount of CO2 that comes from people, vehicles, and industrial. Urban spatial analysis based on satellite image data, using a GIS program is an analysis tool to determine the distribution and growth patterns of green areas. This paper uses a dynamic system model to simulate the conditions of the region against intervention to be performed on potential areas for development of urban forests. The result is a model urban forest area is integrated with a social and economic function to encourage the development of sustainable cities.

  17. Forest crimes as a threat to sustainable forest management

    Directory of Open Access Journals (Sweden)

    S. Özden


    Full Text Available From ancient times to the present day, forest public relations has been an issue on the agenda. This relationship’s purpose was initially needed for shelter and nutrition; however today this process has changed with urbanization, overpopulation and understanding the new functions of forests. When land ownership became a tool of production, offenses occurred in order to convert forestlands to agricultural lands. So the vast majority of the world’s forests have been lost for this reason. Today, deforestation is occurring in tropical countries that are expecting to gain agricultural area. The purpose of this study is to investigate the relationship between urbanization and the qualitative and quantitative characteristics of forest crimes, which are a major obstacle for sustainable forestry. Although forests cover about 27 % of Turkey’s territory, the forests are losing viability; the status of wood raw material per unit area and the total area of the country in the ratio of productive forests are becoming critical in Turkey. Turkey’s rugged terrain and factors such as human interventions, fires, deforestation for agriculture, illegal cuttings, or improper grazing reduce existing forests or cause deterioration of their structure. In the past, deforestation, as a result of human interventions in Turkey, was done by forest villagers who live in rural areas. The forest crimes depend on various socio-economic reasons and have many adverse effects on the sustainability of forest and forest existence. In developed countries, illegal interventions such as opening, grazing, cutting, occupation, use, settlement, or hunting crimes have been largely eliminated because of the absence of cadastral problems, the existence of more responsive people to protect the environment and forests and a rural population, which has a higher standard of living. In the last 20 years, there has been both a dramatic decrease in the population living in rural areas and a

  2. Promoting Sustainable Forest Management Among Stakeholders in the Prince Albert Model Forest, Canada

    Directory of Open Access Journals (Sweden)

    Glen T Hvenegaard


    Full Text Available Model Forests are partnerships for shared decision-making to support social, environmental, and economic sustainability in forest management. Relationships among sustainable forest management partners are often strained, but the Prince Albert Model Forest (PAMF represents a process of effective stakeholder involvement, cooperative relationships, visionary planning, and regional landscape management. This article seeks to critically examine the history, drivers, accomplishments, and challenges associated with the PAMF. Four key phases are discussed, representing different funding levels, planning processes, research projects, and partners. Key drivers in the PAMF were funding, urgent issues, provincial responsibility, core of committed people, evolving governance, desire for a neutral organisation, role of protected areas, and potential for mutual benefits. The stakeholders involved in the Model Forest, including the forest industry and associated groups, protected areas, Aboriginal groups, local communities, governments, and research groups, were committed to the project, cooperated on many joint activities, provided significant staffing and financial resources, and gained many benefits to their own organisations. Challenges included declining funding, changing administrative structures, multiple partners, and rotating representatives. The PAMF process promoted consultative and integrated land resource management in the region, and demonstrated the positive results of cooperation between stakeholders interested in sustainable forest management.

  4. Perceiving sustainable forest spaces: governance aspects of private and company owned forests in North-Karelia, Finland

    Directory of Open Access Journals (Sweden)

    Moritz Albrecht


    Full Text Available The integration of improved environmental or sustainable aspects in forest management is often affiliated with the rise of market-driven governance systems, such as forest certification. In terms of forest resource peripheries, like North-Karelia, Finland, these are often attributed to environmental business and consumer demands from the green Central European markets. While acknowledging these aspects related to the supply chains of wood-based products, this study evaluates the actual perceptions about environmental forest governance and its spaces in the resource peripheries themselves. It displays the perceived changes and practices in forestry by comparing private and corporate ownership and their governance networks. This is accomplished by a qualitative, interview based case study of North Karelian and Finnish forestry actors. Transnational forest governance is hereby treated as a relational space, with forest certification systems as possible technologies used to achieve improved, sustainable forest management. Utilizing the North-Karelian forestry sector, the varying positionalities of actors and institutions within such a relational space shape the knowledge networks, perceptions and decision-making. The study evaluates how these local-global positionalities of actors and individuals shapes their understanding, and guide the direction of sustainable forest management in Finland while it (re-produces opposing regimes of practice. With the discourse on forest certification being twofold, a more complex picture emerges if aspects of even- versus uneven-aged forest management in Finland are integrated. Shaped by the actor’s positionalities and related knowledge networks, perceptions regarding the quality of forest management practices and technologies used to achieve sustainability differ and thereby shape governance processes. The green markets are not perceived as the main driving force and a strong governmental influence, particularly

  5. Is sustainable development attainable? Challenges facing forestry and the forest products industry

    International Nuclear Information System (INIS)

    Wrist, P.E.


    The challenges that face the forest industry in achieving sustainable development are reviewed. Sustainable development is not the same as sustained yield forest management. While sustained yield limits harvesting to an estimate of a forest's incremental annual growth, it is a policy which neither takes into account how improved forest management practices can increase future growth rates nor gives guidance on how multiple uses for the forest resource can be made compatible with periodic harvesting of that resource. Forests, in addition to meeting demands for timber production, must also meet demands for watershed management, recreation, preservation of wildlife and genetic diversity, moderation of climates, carbon sequestration, and land reclamation. Information is lacking from which to develop improved forest management programs that take these demands into account. Questions remain about such matters as the role of plantations in sustainable forestry and the maintenance of natural diversity. Some recent research being undertaken to generate better information for future forestry decision making is outlined, including work on gene pool maintenance, the interdependence of forest ecology and climate, the symbiotic role of mycorrhiza, forest fertilization, and the interdependence of sustainable forestry and sustainable fisheries. In the forest products industry, engineered wood products have been developed that meet tight specifications and require less raw material, and process changes have been introduced that greatly reduce pollutants from pulp manufacture

  11. Sustainable forest management in Poland – theory and practice

    Directory of Open Access Journals (Sweden)

    Kruk Hanna


    Full Text Available The conception of sustainable development has been implemented into practice in numerous economic sectors, including forestry. Forest ecosystems are extremely important in the global ecological system, therefore maintenance and appropriate management of forest resources according to sustainable development principles have engaged a great deal of attention. The concept of sustainable forest management (SFM encompasses three dimensions: ecological, economic and social. A powerful tool to promote SFM are criteria and indicators. The aim of the article was evaluation of SFM in Poland, using one of the methods proposed by the Food and Agriculture Organization (FAO. According to data available, Polish forestry has a number of advantages: Poland has avoided the problem of deforestation, forest area has been permanently increasing, there has been observed improvement of forest health and vitality as well as a significant share of forests has carried out protective functions with no impact on timber production. Poland’s model of SFM is an adaptive process of balancing the ever-changing set of economic, environmental and social expectations. Such a complicated undertaking requires constant assessing and adjusting forest practices, in response to new circumstances, scientific advances and societal input

  16. A Quantitative Index of Forest Structural Sustainability

    Directory of Open Access Journals (Sweden)

    Jonathan A. Cale


    Full Text Available Forest health is a complex concept including many ecosystem functions, interactions and values. We develop a quantitative system applicable to many forest types to assess tree mortality with respect to stable forest structure and composition. We quantify impacts of observed tree mortality on structure by comparison to baseline mortality, and then develop a system that distinguishes between structurally stable and unstable forests. An empirical multivariate index of structural sustainability and a threshold value (70.6 derived from 22 nontropical tree species’ datasets differentiated structurally sustainable from unsustainable diameter distributions. Twelve of 22 species populations were sustainable with a mean score of 33.2 (median = 27.6. Ten species populations were unsustainable with a mean score of 142.6 (median = 130.1. Among them, Fagus grandifolia, Pinus lambertiana, P. ponderosa, and Nothofagus solandri were attributable to known disturbances; whereas the unsustainability of Abies balsamea, Acer rubrum, Calocedrus decurrens, Picea engelmannii, P. rubens, and Prunus serotina populations were not. This approach provides the ecological framework for rational management decisions using routine inventory data to objectively: determine scope and direction of change in structure and composition, assess excessive or insufficient mortality, compare disturbance impacts in time and space, and prioritize management needs and allocation of scarce resources.

  18. Ecological Sustainability of Birds in Boreal Forests

    Directory of Open Access Journals (Sweden)

    Gerald Niemi


    Full Text Available We review characteristics of birds in boreal forests in the context of their ecological sustainability under both natural and anthropogenic disturbances. We identify the underlying ecological factors associated with boreal bird populations and their variability, review the interactions between boreal bird populations and disturbance, and describe some tools on how boreal bird populations may be conserved in the future. The boreal system has historically been an area with extensive disturbance such as fire, insect outbreaks, and wind. In addition, the boreal system is vulnerable to global climate change as well as increasing pressure on forest and water resources. Current knowledge indicates that birds play an important role in boreal forests, and sustaining these populations affords many benefits to the health of boreal forests. Many issues must be approached with caution, including the lack of knowledge on our ability to mimic natural disturbance regimes with management, our lack of understanding on fragmentation due to logging activity, which is different from permanent conversion to other land uses such as agriculture or residential area, and our lack of knowledge on what controls variability in boreal bird populations or the linkage between bird population fluctuations and productivity. The essential role that birds can provide is to clarify important ecological concerns and variables that not only will help to sustain bird populations, but also will contribute to the long-term health of the boreal forest for all species, including humans.

  19. Sustainable management of natural forests in pantanal region, Brazil.

    Directory of Open Access Journals (Sweden)

    Patricia Póvoa de Mattos


    Full Text Available The Pantanal region in Brazil has an area of 140,000 km², with approximately 30 % of natural forests distributed as deciduous, semideciduous, and forested savannas. The subregion of Nhecolandia represents 19 % of this area. There is constant concern about the sustainability of these forested areas, as there is a constant demand for wood for farm maintenance, mainly for making fence poles. The objective of this article is to indicate sustainable forest management practices in the Pantanal region of Nhecolandia. The methodology of this novel approach consisted of the recovery and organization of the available information to calculate the sustainable allowable cut per hectare, considering: cutting cycle, wood stock, periodic annual increment (PAI in percentage of volume from the commercial or interesting species and the stand structure. For forested savannas, the diameter at breast height (DBH of 529 trees per hectare were estimated as follows: 28 % with a DBH lower than 10 cm, 36 % from 10 to 20 cm, 21 % from 20 to 30 cm, 10 % from 30 to 40 cm and only 4 % greater than 40 cm. The estimated total volume per hectare was 84.2 m³ and the estimated basal area was 18.6 m². The forested areas of the Pantanal region present potential for sustainable use. However, due to regional characteristics and the lack of available information, an enhancement in research is recommended to establish a basic management guide to ensure its perpetuation for future generations.

  1. Preservation of wilderness areas in Europe

    Directory of Open Access Journals (Sweden)

    Zoltán Kun


    Full Text Available A unique momentum has been created over the past few years for strengthening the protection of wilderness in Europe. Policy makers started to pay attention to the importance of truly untouched and non-managed areas and the European Parliament adopted a special report on wilderness in February 2009. The report was followed by the EC Presidency Conference in Prague, May 2009, on Wilderness Areas. The most important outcome of this event was the approval of the ‘Agenda for Wilderness’, which eventually led to the inclusion of wilderness in the new EU Biodiversity Strategy. This paper argues that these political successes have yet to be put into practice. Threats to wilderness areas are still increasing and there have been no improvements in the management of these areas. There are emerging threats, especially from tree felling and mining, which is driven by increase in commodity prices. In order to save the last pieces of wilderness in Europe and utilize the current opportunities to restore wilderness areas, science and field conservation must develop a common Wilderness Research Agenda for Europe. The main questions are: (i What are the ecosystem services and benefits that humans obtain for wilderness areas? (ii What is the potential contribution of such wilderness areas for reducing biodiversity loss, halt species extinctions and support biodiversity restoration in Europe? (iii What is the social perception of wilderness in different countries and across different sectors of society? (iv What should be considered wilderness in a densely populated area such as Europe?

  3. Gaps and opportunities for the World Heritage Convention to contribute to global wilderness conservation. (United States)

    Allan, James R; Kormos, Cyril; Jaeger, Tilman; Venter, Oscar; Bertzky, Bastian; Shi, Yichuan; Mackey, Brendan; van Merm, Remco; Osipova, Elena; Watson, James E M


    Wilderness areas are ecologically intact landscapes predominantly free of human uses, especially industrial-scale activities that result in substantial biophysical disturbance. This definition does not exclude land and resource use by local communities who depend on such areas for subsistence and bio-cultural connections. Wilderness areas are important for biodiversity conservation and sustain key ecological processes and ecosystem services that underpin planetary life-support systems. Despite these widely recognized benefits and values of wilderness, they are insufficiently protected and are consequently being rapidly eroded. There are increasing calls for multilateral environmental agreements to make a greater and more systematic contribution to wilderness conservation before it is too late. We created a global map of remaining terrestrial wilderness following the established last-of-the-wild method, which identifies the 10% of areas with the lowest human pressure within each of Earth's 62 biogeographic realms and identifies the 10 largest contiguous areas and all contiguous areas >10,000 km 2 . We used our map to assess wilderness coverage by the World Heritage Convention and to identify gaps in coverage. We then identified large nationally designated protected areas with good wilderness coverage within these gaps. One-quarter of natural and mixed (i.e., sites of both natural and cultural value) World Heritage Sites (WHS) contained wilderness (total of 545,307 km 2 ), which is approximately 1.8% of the world's wilderness extent. Many WHS had excellent wilderness coverage, for example, the Okavango Delta in Botswana (11,914 km 2 ) and the Central Suriname Nature Reserve (16,029 km 2 ). However, 22 (35%) of the world's terrestrial biorealms had no wilderness representation within WHS. We identified 840 protected areas of >500 km 2 that were predominantly wilderness (>50% of their area) and represented 18 of the 22 missing biorealms. These areas offer a starting

  4. Core Content for Wilderness Medicine Training: Development of a Wilderness Medicine Track Within an Emergency Medicine Residency. (United States)

    Schrading, Walter A; Battaglioli, Nicole; Drew, Jonathan; McClure, Sarah Frances


    Wilderness medicine training has become increasingly popular among medical professionals with numerous educational opportunities nationwide. Curricula for fellowship programs and for medical student education have previously been developed and published, but a specific curriculum for wilderness medicine education during emergency medicine (EM) residency has not. The objective of this study is to create a longitudinal wilderness medicine curriculum that can be incorporated into an EM residency program. Interest-specific tracks are becoming increasingly common in EM training. We chose this model to develop our curriculum specific to wilderness medicine. Outlined in the article is a 3-year longitudinal course of study that includes a core didactic curriculum and a plan for graduated level of responsibility. The core content is specifically related to the required EM core content for residency training with additions specific to wilderness medicine for the residents who pursue the track. The wilderness medicine curriculum would give residencies a framework that can be used to foster learning for residents interested in wilderness medicine. It would enhance the coverage of wilderness and environmental core content education for all EM residents in the program. It would provide wilderness-specific education and experience for interested residents, allowing them to align their residency program requirements through a focused area of study and enhancing their curriculum vitae at graduation. Finally, given the popularity of wilderness medicine, the presence of a wilderness medicine track may improve recruitment for the residency program. Copyright © 2017 Wilderness Medical Society.

  14. Effect of Corrupt Behavior of the Forestry Bureaucrats on the Forest Sustainability

    Directory of Open Access Journals (Sweden)

    Sudarsono Soedomo


    Full Text Available 800x600 This article show that corrupt bureaucrats do not always result in a negative effect on the forest sustainability. Even under a certain condition, a corrupt behavior may result in a positive effect on the forest sustainability. An inappropriate policy is more important a cause of the forest sustainability than a corrupt behavior. Therefore, fixing this structural mistake needs to be prioritized in combating the forest destruction, for this structural mistake is the real primary cause of the forest destruction in Indonesia. Fixing this structural mistake is much more effective in combating the forest destruction than finding honest bureaucrats. Keywords:     Birokrat, Distortionary, Nondistortionary, Kelestarian, Korup.

  16. Governing Forest Ecosystem Services for Sustainable Environmental Governance: A Review

    Directory of Open Access Journals (Sweden)

    Shankar Adhikari


    Full Text Available Governing forest ecosystem services as a forest socio-ecological system is an evolving concept in the face of different environmental and social challenges. Therefore, different modes of ecosystem governance such as hierarchical, scientific–technical, and adaptive–collaborative governance have been developed. Although each form of governance offers important features, no one form on its own is sufficient to attain sustainable environmental governance (SEG. Thus, the blending of important features of each mode of governance could contribute to SEG, through a combination of both hierarchical and collaborative governance systems supported by scientifically and technically aided knowledge. This should be further reinforced by the broad engagement of stakeholders to ensure the improved well-being of both ecosystems and humans. Some form of governance and forest management measures, including sustainable forest management, forest certification, and payment for ecosystem services mechanisms, are also contributing to that end. While issues around commodification and putting a price on nature are still contested due to the complex relationship between different services, if these limitations are taken into account, the governance of forest ecosystem services will serve as a means of effective environmental governance and the sustainable management of forest resources. Therefore, forest ecosystem services governance has a promising future for SEG, provided limitations are tackled with due care in future governance endeavors.

  5. Global climate change mitigation and sustainable forest management--The challenge of monitoring and verification

    Energy Technology Data Exchange (ETDEWEB)

    Makundi, Willy R.


    In this paper, sustainable forest management is discussed within the historical and theoretical framework of the sustainable development debate. The various criteria and indicators for sustainable forest management put forth by different institutions are critically explored. Specific types of climate change mitigation policies/projects in the forest sector are identified and examined in the light of the general criteria for sustainable forest management. Areas of compatibility and contradiction between the climate mitigation objectives and the minimum criteria for sustainable forest management are identified and discussed. Emphasis is put on the problems of monitoring and verifying carbon benefits associated with such projects given their impacts on pre-existing policy objectives on sustainable forest management. The implications of such policy interactions on assignment of carbon credits from forest projects under Joint Implementation/Activities Implemented Jointly initiatives are discussed. The paper concludes that a comprehensive monitoring and verification regime must include an impact assessment on the criteria covered under other agreements such as the Biodiversity and/or Desertification Conventions. The actual carbon credit assigned to a specific project should at least take into account the negative impacts on the criteria for sustainable forest management. The value of the impacts and/or the procedure to evaluate them need to be established by interested parties such as the Councils of the respective Conventions.

  10. Thinking globally and acting locally in Mindanao: Supporting the delicate balance of future sustainability in South-East Asian wilderness as well as rural areas

    International Nuclear Information System (INIS)

    Richards, C


    Although models of future sustainability often talk about effectively balancing economic, social and environmental imperatives or factors, in practice this typically remains an elusive ideal. This paper explores the exemplary possibilities but also dilemmas of a proposed initiative in the resource-rich but under-developed Filippino island province of Mindanao to achieve such a delicate balance in practice. This initiative by Raintrust Sustainable Ventures' proposes to link foreign investment in agricultural development to both the social advancement of local tribal peoples and the protection of large amounts of remaining wilderness areas. Such a case study provides an exemplary basis for discussing the challenge of achieving social and environmental as well as economic domains of 'future sustainability'. The crucial supporting role of information and geospatial technologies in the Raintrust plan will also be discussed

  11. Personal Wilderness Relationships: Building on a Transactional Approach (United States)

    Dvorak, Robert G.; Borrie, William T.; Watson, Alan E.


    Wilderness managers are charged with the challenging goal of balancing resource protection and experience quality across a broad, value-laden landscape. While research has provided insight into visitors' motivations and their meanings for wilderness, a struggle exists to implement experiential concepts within current management frameworks. This research posits the human experience of wilderness to be an evolving, enduring relationship, and that research needs can be addressed by conceptualizing and investigating an individuals' personal wilderness relationship. The purpose of this study was to explore wilderness relationships of visitors to the Boundary Waters Canoe Area Wilderness. A predictive model was proposed to investigate the internal dimensions of a visitor's wilderness relationship. A mail-back questionnaire was distributed during the summer of 2007, resulting in a sample of 564 respondents. Data were analyzed using confirmatory factor analysis and structural equation modeling. Results from testing several relationship models provided support for a multidimensional structure consisting of five factors with a single overarching relationship factor. The preferred relationship model indicated the importance of identities and attachment in place relationships. Trust and commitment toward management were also important considerations. This research provided the preliminary evidence for a multidimensional wilderness relationship model and complements a perspective of wilderness experiences as wilderness. Findings may help to reframe decision-making and public-input processes that guide management actions to increased wilderness character protection and facilitate quality wilderness experiences.

  14. Sustainable Development in Northern Africa: The Argan Forest Case

    Directory of Open Access Journals (Sweden)

    Dom Guillaume


    Full Text Available The argan tree is a slow growing tree exclusively endemic in the dry lowlands of Southwest Morocco. The argan forest constitutes a long time ignored specific biotope that has been declared a Biosphere Reserve by UNESCO in 1998. The argan forest is particularly fragile to climate change. Forecasts show annual precipitation levels and prolonged drought periods that could severely threaten the future of the argan forest. In some places, the argan forest is already damaged, resulting in the retreat of the argan tree and the subsequent desert encroachment. An acceleration of this trend would have devastating consequences. In response, some twenty years ago, an ambitious, unique in Northern-Africa, and government-supported program was initiated in Morocco to rescue the argan tree via the sustainable development of the argan forest. Because in the late 1980s, sustainable development in developing countries was often considered as a utopia, the argan forest case represents a sign of progress, as it is also an interesting and unique experience in Africa. This review analyses the process followed, the measures taken, the pitfalls encountered, and the results obtained during the last two decades. It also points out the measures that still need to be taken before declaring the argan forest rescue mission is accomplished.

  20. Evaluation according to criteria and indicators of sustainable forest management: Saçinka Forest Planning Unit

    Directory of Open Access Journals (Sweden)

    Burak Çavdar


    Full Text Available The reasons such as; decrease in forest areas, deterioration in the structure, fragmented structures, decrease in water sources, environmental pollution and increase in carbon level in air are considered as the main sources of problems like global warming and global climate change. Countries have been trying to develop cooperative solutions for these problems since the mid-20th century. Sustainable forest management criteria and indicators, which were outcomes of Biological Diversity Agreement and the processes afterwards, have also been specified in Turkey based on Pan-European process indicators. According to this set of criteria and indicators, data are collected in the scale of Forest Enterprises and the current situation is evaluated in the meetings held by Regional Directorates of Forestry. Most of the data to be evaluated are obtained from forest management plans in the scale of Forest Planning Units and a great deal of economic indicators are dealt in the scale of Forestry Enterprises. Starting from this point of view; this study analyzes the SFM criteria and indicators set data of Saçinka Forest Planning Unit. Accordingly, it examines whether forest ecosystem is conducted in a sustainable way or not.

  6. Geospatial technology perspectives for mining vis-a-vis sustainable forest ecosystems

    Directory of Open Access Journals (Sweden)

    Goparaju Laxmi


    Full Text Available Forests, the backbone of biogeochemical cycles and life supporting systems, are under severe pressure due to varied anthropogenic activities. Mining activities are one among the major reasons for forest destruction questioning the survivability and sustainability of flora and fauna existing in that area. Thus, monitoring and managing the impact of mining activities on natural resources at regular intervals is necessary to check the status of their depleted conditions, and to take up restoration and conservative measurements. Geospatial technology provides means to identify the impact of different mining operations on forest ecosystems and helps in proposing initiatives for safeguarding the forest environment. In this context, the present study highlights the problems related to mining in forest ecosystems and elucidates how geospatial technology can be employed at various stages of mining activities to achieve a sustainable forest ecosystem. The study collates information from various sources and highlights the role of geospatial technology in mining industries and reclamation process.

  9. Wild Carpathia Future Development: From Illegal Deforestation to ORV Sustainable Recreation

    Directory of Open Access Journals (Sweden)

    Mihai Voda


    Full Text Available Romanian Wild Carpathia constitutes the ultimate pristine wilderness of the old European continent. Carpathian Mountains landscape experiences and outdoor recreation represents quite unique cultural ecosystem services. The new annotations to the Forest Law are restricting any public access in the woods without authorities’ pre-approval for organised sport, leisure and tourism activities. However, off road vehicle (ORV recreation is a popular activity and a growing transparency concern of National Forest Administration Authorities that is not managed accordingly. Here we show that our ORV recreation frame model can securely allow public access and protect all Romanian mountains. Our results demonstrate how growing ORV recreation popularity can be used in an honest and open way if it is well organized and controlled. We anticipate our assay to be a starting point for a regional and national forest administration sustainable development plan. Furthermore, stopping illegal forest activities is a major target of the anti-logging movement. A well-defined assay for the ORV recreation frame model will be relevant for such developments.

  11. Forest Management Challenges for Sustaining Water Resources in the Anthropocene

    Directory of Open Access Journals (Sweden)

    Ge Sun


    Full Text Available The Earth has entered the Anthropocene epoch that is dominated by humans who demand unprecedented quantities of goods and services from forests. The science of forest hydrology and watershed management generated during the past century provides a basic understanding of relationships among forests and water and offers management principles that maximize the benefits of forests for people while sustaining watershed ecosystems. However, the rapid pace of changes in climate, disturbance regimes, invasive species, human population growth, and land use expected in the 21st century is likely to create substantial challenges for watershed management that may require new approaches, models, and best management practices. These challenges are likely to be complex and large scale, involving a combination of direct and indirect biophysical watershed responses, as well as socioeconomic impacts and feedbacks. We discuss the complex relationships between forests and water in a rapidly changing environment, examine the trade-offs and conflicts between water and other resources, and propose new management approaches for sustaining water resources in the Anthropocene.

  14. Europe’s Wild Heart – still beating? Experiences from a new transboundary wilderness area in the middle of the Old Continent

    Directory of Open Access Journals (Sweden)

    Zdenka Křenová


    Full Text Available The face of Europe has been shaped by human civilization for centuries and wilderness did not only vanish from the continent’s surface but also from humans’ minds and experiences. However, there are still a few places left, which have remained more or less unmodified and have at least the potential for rewilding. Among them are the Šumava National Park and the neighbouring Bavarian Forest NP, which together create a unique forest zone in the middle of Europe susceptible to host and demonstrate natural forest dynamics and ecosystem processes. This is also a large and very important Natura 2000 area. Transboundary cooperation between both National parks has improved since 1990, when the former Iron Curtain Corridor was opened, and culminated by the project Europe’s Wild Heart. The main goal of the project Europe’s Wild Heart, which started in 2008, was to develop a transboundary wilderness area in the core zones of the two national parks – BFNP and ŠNP. The project area was 13,060 ha and a “life story” of this project is described in this paper. A common “vision 2020” was signed where both parks committed among other things “to achieve a joint core area of about 15,000 ha with harmonized management principles, information services and monitoring networks to officially become the first and largest transboundary wilderness area in Central Europe”. Unfortunately, the bark beetle outbreak which followed the Kyrill hurricane in 2008 and 2009 escalated the discussion about appropriate forest management in the ŠNP. Opponents of the national park principles, non-intervention and wilderness concept became more and more vocal. The situation escalated after the election in 2010 when the Green Party was replaced by conservatives (ODS – Civic Democratic Party at the Czech Ministry of Environment. Clear cuttings were started in some former non-intervention parts of the ŠNP and hunting was again allowed in the core zone. Since then

  15. Accounting of forest resources in the framework of sustainable development

    Directory of Open Access Journals (Sweden)

    I.V. Zamula


    Full Text Available Nowadays, deforestation of territories and degradation of forest resources is a global problem as it leads to a climate change, soil degradation, the decline in natural reproduction of forest resources and to the disappearance of many valuable species of forest cultures. Due to the importance of the preservation of forest resources for environment it is necessary to revise the conceptual approach to the reflection of such resources both at the micro- and at the macroeconomic level. Preservation, rational use and reproduction of forest resources is one of the priorities of forestry development inUkraine. Accounting is a tool which allows to form the information about the condition and availability of forest resources. In this regard, we consider that the accounting information is an important tool for the preservation of forest assets and the reduction of anthropogenic impacts on these slowly recovering natural resources. The reflection of forest resources in accounting should be implemented on the basis of the rules defined in the P(S BU 30 called «Biological Assets» and IAS 41 called «Agriculture». In addition, we consider that while reflecting of forest resources in accounting it’s necessary to take into account the life cycle of the tree stand which consists of several stages where each one should be taken into account in the recognition of expenses on their reproduction. For the formation of analytical cuts of the costs of care for the forest resources and their protection is proposed to open the following 3 sub-accounts to the account 155 called «Expenses on the formation of forest resources»: the first is «Expenses on the landing of forest cultures», the second is «Expenses on care for forest resources» and the third one is «Expenses on the protection of forest resources». Sustainable forest management involves the reproduction of forest resources. One of the main criteria for evaluating the effectiveness of forest management

  17. Keeping it wild: mapping wilderness character in the United States. (United States)

    Carver, Steve; Tricker, James; Landres, Peter


    A GIS-based approach is developed to identify the state of wilderness character in US wilderness areas using Death Valley National Park (DEVA) as a case study. A set of indicators and measures are identified by DEVA staff and used as the basis for developing a flexible and broadly applicable framework to map wilderness character using data inputs selected by park staff. Spatial data and GIS methods are used to map the condition of four qualities of wilderness character: natural, untrammelled, undeveloped, and solitude or primitive and unconfined recreation. These four qualities are derived from the US 1964 Wilderness Act and later developed by Landres et al. (2008a) in "Keeping it Wild: An Interagency Strategy to Monitor Trends in Wilderness Character Across the National Wilderness Preservation System." Data inputs are weighted to reflect their importance in relation to other data inputs and the model is used to generate maps of each of the four qualities of wilderness character. The combined map delineates the range of quality of wilderness character in the DEVA wilderness revealing the majority of wilderness character to be optimal quality with the best areas in the northern section of the park. This map will serve as a baseline for monitoring change in wilderness character and for evaluating the spatial impacts of planning alternatives for wilderness and backcountry stewardship plans. The approach developed could be applied to any wilderness area, either in the USA or elsewhere in the world. Copyright © 2013 Elsevier Ltd. All rights reserved.

  20. The Waswanipi Cree Model Forest: Demonstrating Aboriginal leadership in sustainable forest management

    Energy Technology Data Exchange (ETDEWEB)

    Jolly, A.


    Experiences of the Waswanipi Cree community in being partners in sustainable forest management are discussed. The Waswanipi Cree Model Forest was designated as such in 1997. Since then, it has come to be seen as a forum for the community to express its needs, goals and objectives for the future, and as the first opportunity for the Cree community to exercise leadership and decision-making authority related to land management issues. The Waswanipi land is situated on the southernmost tip of eastern James Bay. It extends to some 35,000 sq km, divided into 52 family hunting territories, called traplines. Each trapline has a designated custodian, who is responsible for ensuring that wildlife is harvested in a sustainable manner. Community life is organized around the traplines, although families will sometimes temporarily relocate close to paid employment opportunities. Nevertheless, the purpose of employment is always to return to the bush, with sufficient materials and supplies to last the hunting and trapping season. Prior to the designation of the Model Forest, the major problems have been the rate and extent of forestry activities on Cree land by outside timber companies, the absence of opportunities for the Cree to have a meaningful role in decisions that impacted their future and the difficulties of convincing government experts and forestry companies to allow the Cree to bring their experience-based knowledge to bear on forest resource management issues. The manner in which the new partnership resulting from the designation of the Model Forest is opening the way to better understanding, mitigation of the negative effects of forestry operations on traplines, mediation of conflicts between trappers and forestry companies with timber licences on Waswanipi land, are described as one of the major achievements of the Model Forest Program. The rate and extent of cutting continues to be a problem, however, there are signs of a growing understanding among the timber

  5. Spatial overlap between environmental policy instruments and areas of high conservation value in forest. (United States)

    Sverdrup-Thygeson, Anne; Søgaard, Gunnhild; Rusch, Graciela M; Barton, David N


    In order to safeguard biodiversity in forest we need to know how forest policy instruments work. Here we use a nationwide network of 9400 plots in productive forest to analyze to what extent large-scale policy instruments, individually and together, target forest of high conservation value in Norway. We studied both instruments working through direct regulation; Strict Protection and Landscape Protection, and instruments working through management planning and voluntary schemes of forest certification; Wilderness Area and Mountain Forest. As forest of high conservation value (HCV-forest) we considered the extent of 12 Biodiversity Habitats and the extent of Old-Age Forest. We found that 22% of productive forest area contained Biodiversity Habitats. More than 70% of this area was not covered by any large-scale instruments. Mountain Forest covered 23%, while Strict Protection and Wilderness both covered 5% of the Biodiversity Habitat area. A total of 9% of productive forest area contained Old-Age Forest, and the relative coverage of the four instruments was similar as for Biodiversity Habitats. For all instruments, except Landscape Protection, the targeted areas contained significantly higher proportions of HCV-forest than areas not targeted by these instruments. Areas targeted by Strict Protection had higher proportions of HCV-forest than areas targeted by other instruments, except for areas targeted by Wilderness Area which showed similar proportions of Biodiversity Habitats. There was a substantial amount of spatial overlap between the policy tools, but no incremental conservation effect of overlapping instruments in terms of contributing to higher percentages of targeted HCV-forest. Our results reveal that although the current policy mix has an above average representation of forest of high conservation value, the targeting efficiency in terms of area overlap is limited. There is a need to improve forest conservation and a potential to cover this need by better

  6. Carbon sequestration, biological diversity, and sustainable development: Integrated forest management

    Energy Technology Data Exchange (ETDEWEB)

    Cairns, M.A. (Environmental Research Lab., Corvallis, OR (United States)); Meganck, R.A. (United Nations Environment Programme for the Wider Caribbean, Kingston (Jamaica))

    Tropical deforestation provides a significant contribution to anthropogenic increases in atmospheric CO[sub 2] concentration that may lead to global warming. Forestation and other forest management options to sequester CO[sub 2] in the tropical latitudes may fail unless they address local economic, social, environmental, and political needs of people in the developing world. Forest management is discussed in terms of three objectives: Carbon sequestration, sustainable development, and biodiversity conservation. An integrated forest management strategy of land-use planning is proposed to achieve these objectives and is centered around: Preservation of primary forest, intensified use of nontimber resources, agroforestry, and selective use of plantation forestry. 89 refs., 1 fig., 1 tab.

    Šijačić-Nikolić Mirjana


    Full Text Available Program for conservation and sustainable utilization of forest genetic resources has been defined for 2016-2025 period and it is a base for concrete activities in this field. This Program could be divided into several parts that deal with: the legal framework for the conservation and sustainable utilization of forest genetic resources; status of forest genetic resources in Serbia; previous activities on the conservation of forest genetic resources; and objectives, priorities and measures of conservation. The Program should have an impact on the development of the forestry sector through the following activities: conservation and sustainable utilization of the available gene pool; improving forest management in accordance with conservation principles; improving the production of reproductive material of forest trees; make the public awareness of the need for conservation and sustainable utilization of forest genetic resources; fulfillment of international obligations related to this field and the possibility of joining FAO activities related to forest genetic resources - development of the national report as a part of the publication The State of the World's Forest Genetic Resources. Implementation of the Program will depend upon raising the awareness on the importance, conservation and sustainable utilization of forest genetic resources, as a precondition for the forests survival; it will depend of funds that will be allocated for this purpose and enthusiasm of people who deal with these issues.

  9. Sustaining forest landscape connectivity under different land cover change scenarios

    Energy Technology Data Exchange (ETDEWEB)

    Rubio, L.; Rodriguez-Freire, M.; Mateo-Sanchez, M. C.; Estreguil, C.; Saura, S.


    Managing forest landscapes to sustain functional connectivity is considered one of the key strategies to counteract the negative effects of climate and human-induced changes in forest species pools. With this objective, we evaluated whether a robust network of forest connecting elements can be identified so that it remains efficient when facing different types of potential land cover changes that may affect forest habitat networks and ecological fluxes. For this purpose we considered changes both in the forested areas and in the non-forest intervening landscape matrix. We combined some of the most recent developments in graph theory with models of land cover permeability and least-cost analysis through the forest landscape. We focused on a case of study covering the habitat of a forest dwelling bird (nuthatch, Sitta europaea) in the region of Galicia (NW Spain). Seven land-use change scenarios were analysed for their effects on connecting forest elements (patches and links): one was the simplest case in which the landscape is represented as a binary forest/non-forest pattern (and where matrix heterogeneity is disregarded), four scenarios in which forest lands were converted to other cover types (to scrubland due to wildfires, to extensive and intensive agriculture, and to urban areas), and two scenarios that only involved changes in the non-forested matrix (re naturalization and intensification). Our results show that while the network of connecting elements for the species was very robust to the conversion of the forest habitat patches to different cover types, the different change scenarios in the landscape matrix could more significantly weaken its long-term validity and effectiveness. This is particularly the case when most of the key connectivity providers for the nuthatch are located outside the protected areas or public forests in Galicia, where biodiversity-friendly measures might be more easily implemented. We discuss how the methodology can be applied to

  13. The evolution of international policies and mechanisms to advance sustainable forest management and mitigate global climate change

    International Nuclear Information System (INIS)

    Bologna, J.; Lyke, J.; Theophile, K.


    Scientific findings regarding global climate change and deforestation led industrialized nations to bring both issues to the forefront of an international dialogue on the environment. International institutional attention to deforestation began in 1985 with the Tropical Forestry Action Program which helped countries develop plans for sustainable forest management. A few years later, the International Tropical Timber Organization, though designed to facilitate tropical timber trade, adopted guidelines for sustainable management of tropical production forests. Next, the activities before and after UNCED established a general set of forest principles and regional efforts to define sustainable forest management. The World Bank has also sought to reduce past lending failures that led to deforestation and other environmental degradation, through programmatic redirections and macro-economic policy reforms. Finally, through innovative financial incentives, industrialized and developing countries are identifying opportunities to offset debts and increase economic development without depleting forest resources. Collectively, these efforts have let to some trends that support sustainable forest management and mitigate climate change. The upcoming years will see a proactive set of multilateral programs to address deforestation, an increasing link between trade and the environment, and more uses of financial incentives to encourage sustainable forest management

  15. Relationship of various factors affecting the sustainable private forest management at Pajangan District, Special Regions Yogyakarta, Indonesia (United States)

    Widayanto, B.; Karsidi, R.; Kusnandar; Sutrisno, J.


    Forests have a role and function in providing good atmosphere with stable oxygen content and affecting global climate stability. Good forest management will provide stable climatic conditions in global climate change. A good forest is managed to provide a sustainable environment condition. This study aims to analyze the relationship of various factors affecting the sustainability of private forests management. This research is a quantitative research with survey method and determination of sampling are was by purposive sampling. Sampling method using multiple stage cluster sampling with 60 samples. From the results it was found that the successful sustainable private forest management influenced by various factors, such as group dynamics, stakeholder support, community institutions, and farmer participation. The continuity of private forest management is determined by the fulfillment of economic, social and environmental dimensions. The most interesting finding is that the group dynamics conditions are very good, whereas the sense of togetherness among community is very strong under limited resources managing private forests. The sense of togetherness resulted creativity to diversify business and thus reduced the pressure in exploiting the forest. Some people think that managing the people's forest as a culture so that its existence can be more sustainable.

  16. Hurdles to Forest Friendly Farming: Sustainability Lessons from Southeastern Mexico

    Directory of Open Access Journals (Sweden)

    Eric Keys


    Full Text Available Worldwide the search is on for sustainable solutions to the competing needs for forest conservation and agricultural development. A strategy with contemporary salience arises in intensive, sedentarized agriculture that can protect forests and enhance livelihoods for forest dwellers. This paper investigates why intensive agriculture does not limit deforestation in southeastern Mexico’s Calakmul Municipality. It argues that agriculture faces challenges from a range of biophysical and socioeconomic factors in tropical regions and that this encourages expanded land use for intensive farmers.

  17. Ecosystemic forest management approach to ensure forest sustainability and socio-economic development of forest dependent communities: Evidence from Southeast Cameroon

    Directory of Open Access Journals (Sweden)

    J. Mbairamadji


    Full Text Available Forests provide a full spectrum of goods and services that contribute to the socio-economic development of forest dependent communities. In tropical countries, the diversity of stakeholders depending on forests with their divergent interests and expectations, make sustainable forest management (SFM difficult to achieve. Although several studies advocate the decentralization of forest management and public participation as important processes for SFM, little has been done to demonstrate how these processes could contribute to forest sustainability and socioeconomic development of forest dependent communities. Moreover, almost no seminal paper has demonstrated how to integrate the ecological, economical and social issues of forest management, which have nevertheless been recognized as essential for sustainable forest management. This study develops an ecosystemic forest management approach based on “Stakeholder-Resource-Usage-Institution” dynamics as an appropriate framework for ensuring forest sustainability and socio-economic development. This approach is supported with lessons drawn on the limitations and pitfalls of the traditional forest management approach in Southeast Cameroon.Les forêts fournissent toute une gamme de biens et de services qui contribuent au développement socio-économique des communautés dépendantes de la forêt. Dans les régions tropicales, la diversité des parties prenantes qui dépendent des forêts rend la gestion durable des forêts difficile du fait d’attentes et d’intérêts divergents. Bien que plusieurs études estiment la décentralisation de la gestion des forêts et la participation publique comme importantes pour la gestion durable des forêts, peu d’initiatives ont été prises pour démontrer la manière dont ces actions pourraient contribuer à la durabilité de la forêt et au développement socio-économique des communautés dépendant de la forêt.

    Church, S.E.; Close, T.J.


    The Goat Rocks Wilderness and adjacent roadless areas are a rugged, highly forested, scenic area located on the crest of the Cascade Range in south-central Washington. Several mineral claims have been staked in the area. Mineral surveys were conducted. Geochemical, geophysical, and geologic investigations indicate that three areas have probable mineral-resource potential for base metals in porphyry-type deposits. Available data are not adequate to permit definition of the potential for oil and gas. There is little likelihood for the occurrence of other kinds of energy resources in the area. Evaluation of resource potential in the three areas identified as having probable mineral-resource potential could be improved by more detailed geochemical studies and geologic mapping.

  3. Sustainable Forest Management in a Mediterranean region: social preferences

    Energy Technology Data Exchange (ETDEWEB)

    Maroto, C.; Segura, M.; Ginestar, C.; Uriol, J.; Segura, B.


    Aim of study: There is a lack of empirical research that deals with sustainable forest management in Mediterranean regions, among the most vulnerable ecosystems. The main purpose of this work is to define the strategic criteria and objectives for sustainable forest management and aggregate the preferences of stake holders in a Mediterranean region, using AHP and Goal Programming. Area of study: Valencian Community (Spain). Material and Methods: Firstly, we identified forest stake holders and structured a decision hierarchy. Then a workshop was carried out to test and validate the proposed criteria and objectives, as well as a survey to determine social preferences. Secondly, another survey was conducted amongst experts to prioritize action plans. Main results: Stake holders preferences gave the greatest importance to the environmental criteria (hydrological regulation and erosion, climate change mitigation and biodiversity) with an average weight of 40%. Social criteria (employment, recreational activities and landscape) had a weight of 38% and 22% the economic criteria case (wood, hunting and fishing, livestock, renewable energies, rural tourism and mining). The results showed that new products and services such as tourism, renewable energies, landscape, hydrological regulation and erosion control, biodiversity or climate change mitigation are very relevant objectives. We also prioritized action plans comparing them with the distribution of the administration budget. Research highlights: The environmental and social criteria are much more important than the economic ones in the regional planning of the Mediterranean forest, regardless of the method used to aggregate the social preferences and if the forest is public or private.

  5. Criteria and indicators for sustainable forest management: an alternative for monitoring

    Directory of Open Access Journals (Sweden)

    Jorge Luis Cué García


    Full Text Available The work was developed in the province of Cienfuegos, Cuba, with the hope of presenting an alternative methodology for monitoring criteria and indicators of sustainable forest management. Participatory workshops were used with actors and makers of SilviculturalUnits in the definition of criteria and indicators, based on the rules set forth by Herrero (2005. The Delphi method was used in the validation of the proposal. A hierarchical system that facilitates standardization of indicators and their aggregation to indices as well as the procedural guide indicators and checklist of them was used. The adequacy of Sustainability Barometer Prescott-Allen, 1997, quoted by Van Bellen (2004 was performed. The results of the analysis of the reliability of the instrument applied to the expert are acceptable because the Hotelling T2 value was 322.46 p = 0.007, there is a strong significant correlation between the elements of the instrument, expressed in an intraclass correlation coefficient from 0.756 to p = 0.038, Alpha reliability coefficient Cronbach 0.806, Spearman-Brown coefficient equal to 0.656 and Guttman split halves coefficient of 0.606. This alternative ensures a more comprehensive and holistic observance of the attributes of a system of sustainability indicators in the field of specialized forest Cuban business sector, enabling the assessment of the trend of sustainable forest management according to the specifics of each forestry unit.

    Keith, T.E.C.; Causey, J.D.


    A mineral survey of the Mount Hood Wilderness, Oregon, was conducted. Geochemical data indicate two areas of substantiated mineral-resource potential containing weak epithermal mineralization: an area of the north side of Zigzag Mountain where vein-type lead-zinc-silver deposits occur and an area of the south side of Zigzag Mountain, where the upper part of a quartz diorite pluton has propylitic alteration associated with mineralization of copper, gold, silver, lead, and zinc in discontinuous veins. Geothermal-resource potential for low- to intermediate-temperature (less than 248 degree F) hot-water systems in the wilderness is probable in these areas. Part of the wilderness is classified as a Known Geothermal Resource Area (KGRA), which is considered to have probable geothermal-resource potential, and two parts of the wilderness have been included in geothermal lease areas.

  8. The sustainable management and protection of forests: analysis of the current position globally. (United States)

    Freer-Smith, Peter; Carnus, Jean-Michel


    The loss of forest area globally due to change of land use, the importance of forests in the conservation of biodiversity and in carbon and other biogeochemical cycles, together with the threat to forests from pollution and from the impacts of climate change, place forestry policy and practice at the center of global environmental and sustainability strategy. Forests provide important economic, environmental, social, and cultural benefits, so that in forestry, as in other areas of environmental policy and management, there are tensions between economic development and environmental protection. In this article we review the current information on global forest cover and condition, examine the international processes that relate to forest protection and to sustainable forest management, and look at the main forest certification schemes. We consider the link between the international processes and certification schemes and also their combined effectiveness. We conclude that in some regions of the world neither mechanism is achieving forest protection, while in others local or regional implementation is occurring and is having a significant impact. Choice of certification scheme and implementation of management standards are often influenced by a consideration of the associated costs, and there are some major issues over the monitoring of agreed actions and of the criteria and indicators of sustainability. There are currently a number of initiatives seeking to improve the operation of the international forestry framework (e.g., The Montreal Process, the Ministerial Convention of the Protection of Forests in Europe and European Union actions in Europe, the African Timber Organisation and International Tropical Timber Organisation initiative for African tropical forest, and the development of a worldwide voluntary agreement on forestry in the United Nations Forum on Forests). We suggest that there is a need to improve the connections between scientific understanding

  11. Medical Oversight, Educational Core Content, and Proposed Scopes of Practice of Wilderness EMS Providers: A Joint Project Developed by Wilderness EMS Educators, Medical Directors, and Regulators Using a Delphi Approach. (United States)

    Millin, Michael G; Johnson, David E; Schimelpfenig, Tod; Conover, Keith; Sholl, Matthew; Busko, Jonnathan; Alter, Rachael; Smith, Will; Symonds, Jennifer; Taillac, Peter; Hawkins, Seth C


    A disparity exists between the skills needed to manage patients in wilderness EMS environments and the scopes of practice that are traditionally approved by state EMS regulators. In response, the National Association of EMS Physicians Wilderness EMS Committee led a project to define the educational core content supporting scopes of practice of wilderness EMS providers and the conditions when wilderness EMS providers should be required to have medical oversight. Using a Delphi process, a group of experts in wilderness EMS, representing educators, medical directors, and regulators, developed model educational core content. This core content is a foundation for wilderness EMS provider scopes of practice and builds on both the National EMS Education Standards and the National EMS Scope of Practice Model. These experts also identified the conditions when oversight is needed for wilderness EMS providers. By consensus, this group of experts identified the educational core content for four unique levels of wilderness EMS providers: Wilderness Emergency Medical Responder (WEMR), Wilderness Emergency Medical Technician (WEMT), Wilderness Advanced Emergency Medical Technician (WAEMT), and Wilderness Paramedic (WParamedic). These levels include specialized skills and techniques pertinent to the operational environment. The skills and techniques increase in complexity with more advanced certification levels, and address the unique circumstances of providing care to patients in the wilderness environment. Furthermore, this group identified that providers having a defined duty to act should be functioning with medical oversight. This group of experts defined the educational core content supporting the specific scopes of practice that each certification level of wilderness EMS provider should have when providing patient care in the wilderness setting. Wilderness EMS providers are, indeed, providing health care and should thus function within defined scopes of practice and with

Habitat types and indicator species are identified to measure environmental quality. Working towards an integrated approach to conservation, a range of options that will result in sustainable forest management are then considered. For beech forests light heterogeneity emerges as a crucial management target to ensure tree species richness and structural diversity as a basis for saving indicator species such as Morimus funereus, Cucujus cinnaberinus, Bolitophagus reticulatus and Xestobium austriacum. For spruce forests thinning over a broad range of diameters and maintenance of veteran trees would provide habitats for indicator species such asOlisthaerus substriatus. The populations of a number of bird species would be increased by strip-harvesting slopes: species such as Tetrao urogallus, Bonasia bonasia and Ficedula parva prefer forest margins. Steep slopes, and the areas around springs and watercourses, as well as rock faces, should remain unmanaged. Future management should start with a grid-based inventory to create an objective database of forest structure and life. An example is presented for high-elevation spruce forest. The inventory should quantify the variations in diameter, height and volume of trees per unit area. Such data would allow the advanced planning of forest operations. We discuss a wide range of administrative and organizational changes; changes that are needed for the sustainable forest management of the vast close-to-natural forests of the Muntii Fagaras, the maintenance of the Nardusgrasslands and the protection of wetland vegetation around springs and streams in this Natura 2000-area.

  1. Bryophytes from Tuxedni Wilderness area, Alaska (United States)

    Schofield, W.B.; Talbot, S. S.; Talbot, S.L.


    The bryoflora of two small maritime islands, Chisik and Duck Island (2,302 ha), comprising Tuxedni Wilderness in western lower Cook Inlet, Alaska, was examined to determine species composition in an area where no previous collections had been reported. The field study was conducted from sites selected to represent the totality of environmental variation within Tuxedni Wilderness. Data were analyzed using published reports to compare the bryophyte distribution patterns at three levels, the Northern Hemisphere, North America, and Alaska. A total of 286 bryophytes were identified: 230 mosses and 56 liverworts. Bryum miniatum, Dichodontium olympicum, and Orthotrichum pollens are new to Alaska. The annotated list of species for Tuxedni Wilderness expands the known range for many species and fills distribution gaps within Hulte??n's Central Pacific Coast district. Compared with bryophyte distribution in the Northern Hemisphere, the bryoflora of Tuxedni Wilderness primarily includes taxa of boreal (61%), montane (13%), temperate (11%), arctic-alpine (7%), cosmopolitan (7%), distribution; 4% of the total moss flora are North America endemics. A brief summary of the botanical exploration of the general area is provided, as is a description of the bryophytes present in the vegetation and habitat types of Chisik and Duck Islands.

  2. Application of Network Analysis for Development and Promotion of Sustainable Tourism in Public Forests

    Directory of Open Access Journals (Sweden)

    Brach Michał


    Full Text Available The issue of sustainable tourism within valuable natural areas has been extensively discussed ever since the emergence of sustainable development philosophy in the 1990s. In view of growing public interest in nature recreation and tourism development, the importance of addressing this subject matter has hitherto increased significantly. The main objective of the present paper was to offer a tool for supporting development and promotion of sustainable tourism in Poland’s forests managed by the State Forests - National Forest Holding. GIS technology, and specific tools for network analysis were used in the project. During task realization, only free and open software sources were used. The work was performed based on the example of the Forest District Żołędowo (Regional Directorate of State Forests in Toruń, Poland with the use of District’s spatial data resources. A web application was created to present information about tourist attractions and infrastructure on an interactive map with tools for route planning. As a result, there has been developed the web mapping application which provides general access to tourism related information and enables planning touristic routes by pre-specified criteria. Implemented routing algorithms can help traffic management and further protection of the areas vulnerable to anthropogenic pressures. The system created not only promotes attractive tourist sites but also, supports targeting tourist traffic, and accordingly - adds to the progress of sustainable tourism

  7. Wilderness experience in Rocky Mountain National Park 2002; report to respondents (United States)

    Schuster, Elke; Johnson, S. Shea; Taylor, Jonathan G.


    A substantial amount of backcountry (about 250,000 acres) in Rocky Mountain National Park [RMNP of the Park] may be designated as wilderness areas in the coming years. Currently, over 3 million visitors drives through the park on Trail Ridge Road, camp in designated campgrounds, day hike, etc. each year. Many of those visitors also report using the backcountry-wilderness areas that are not easily accessible by roads or trails. Use of the backcountry is growing at RMNP and is accompanied by changing visitor expectations and preferences for wilderness management. For these reasons it is of great importance for the Park to periodically assess what types of environments and conditions wilderness users seek to facilitate a quality experience. To assist in this effort, the Political Analysis and Science Assistance [PSAS] program / Fort Collins Center / U.S. Geological Survey, in close collaboration with personnel and volunteers from RMNP, as well as the Natural Resource Recreation and Tourism [NRRT] Department at Colorado State University, launched a research effort in the summer of 2002 to investigate visitorsa?? wilderness experiences in the Park. Specifically, the purpose of this research was: (1) To determine what constitutes a wilderness experience; (2) To identify important places, visual features, and sounds essential to a quality wilderness experience and; (3) To determine what aspects may detract from wilderness experience. Thus, answers to these questions should provide insight for Park managers about visitorsa?? expectation for wilderness recreation and the conditions they seek for quality wilderness experiences. Ultimately, this information can be used to support wilderness management decisions within RMNP. The social science technique of Visitor Employed Photography [VEP] was used to obtain information from visitors about wilderness experiences. Visitors were selected at random from Park-designated wilderness trails, in proportion to their use, and asked to

  8. Wilderness Medical Society practice guidelines for the use of epinephrine in outdoor education and wilderness settings: 2014 update. (United States)

    Gaudio, Flavio G; Lemery, Jay; Johnson, David E


    The Epinephrine Roundtable took place on July 27, 2008, during the 25th Annual Meeting of the Wilderness Medical Society (WMS) in Snowmass, CO. The WMS convened this roundtable to explore areas of consensus and uncertainty in the field treatment of anaphylaxis. Panelists were selected on the basis of their relevant academic or professional experience. There is a paucity of data that address the treatment of anaphylaxis in the wilderness. Anaphylaxis is a rare disease, with a sudden onset and drastic course that does not lend itself to study in randomized, controlled trials. Therefore, the panel endorsed the following position based on the limited available evidence and review of published articles, as well as expert consensus. The position represents the consensus of the panelists and is endorsed by the WMS. In 2014, the authors reviewed relevant articles published since the Epinephrine Roundtable. The following is an updated version of the original guidelines published in Wilderness & Environmental Medicine 2010;21(4):185-187. Copyright © 2014 Wilderness Medical Society.

  11. Fragile Social Norms: (Un Sustainable Exploration of Forest Products

    Directory of Open Access Journals (Sweden)

    Decio Zylbersztajn


    Full Text Available The exhaustion of natural resources is a central problem in the international agenda. The particular case of Amazon forest is at the top on the international environmental debate. Two related problems are keys to be considered in the discussion of sustainable development in this region. First the predatory use of the natural resources of the forest mainly timber and genetic resources. Second the recognition of the existence of a population of around 20 million inhabitants in the region defined as “Legal Amazon Area”, aiming the improvement on the living conditions, enhancement of income level and acceleration of development. How to match both objectives is a puzzle faced by the present generation.The region is populated by initiatives of international non-governmental-organizations, most of them carrying good intentions but lacking the necessary knowledge on local formal and informal institutions to find ways to reach sustainable development. The result is the accelerated process of natural resources depletion, and social disorganization. The case of the production of Brazilian Nuts stands as a corollary of the lack of an institutional structure of property rights that does not provide incentives for sustainable development. The opposite effect is being observed as a result of the fragility of observable institutional arrangements.The case provides the counterfactual for the analysis of Ostrom (1990; 2008, where she presents virtuous cases of sustainable exploration of natural resources, mostly based on informal but solid institutions.

  14. Legal Harvesting, Sustainable Sourcing and Cascaded Use of Wood for Bioenergy: Their Coverage through Existing Certification Frameworks for Sustainable Forest Management

    Directory of Open Access Journals (Sweden)

    Richard Sikkema


    Full Text Available The first objective of this paper was to provide an inventory of developments of certification schemes for sustainable biomass production, following recent EU legislation (both formalized and under development. One main pillar is the EU Timber Regulation for legal harvesting; a second one is the EU’s 2010 recommendations for sustainable woody biomass sourcing for energy; the third one is the EU Waste Directive. The second objective was to benchmark the coverage of this (draft legislation, when wood product certificates for sustainable forest management (SFM are used as proof of the related legislative requirements. We studied North America, as it is a major biomass supplier to the EU-28. Together with existing forest legislation in the US and Canada, SFM certificates are actively used to cover the EU’s (draft legislation. However, North American forests are only partially certified with fibers coming from certified forests; these are referred to as forest management (FM fibers. Other certified fibers should come from complementary risk assessments downstream in the supply chain (risk based fibers. Our benchmark concludes that: (a FM fiber certification by the Forest Stewardship Council (FSC and the Program for the Endorsement of Forest Certification (PEFC international standards show the highest level of coverage with EU’s (draft legislation; (b There is insufficient coverage for risk based fibers by FSC Controlled Wood (FSC-CW, PEFC Due Diligence (PEFC-DD, or SFI-fiber sourcing (SFI-FS. Other weaknesses identified for elaboration are: (c Alignment in definitions are needed, such as for primary forest, high carbon stock, and wood waste (cascading; (d Imperfect mass balance (fiber check downstream needs to be solved, as non-certified fiber flows are inadequately monitored; (e Add-on of a GHG calculation tool is needed, as GHG life cycle reporting is not covered by any of the SFM frameworks.

  17. Wilderness Preparticipation Evaluation and Considerations for Special Populations. (United States)

    Joy, Elizabeth; Van Baak, Karin; Dec, Katherine L; Semakula, Barbara; Cardin, Ashlea D; Lemery, Jay; Wortley, George C; Yaron, Michael; Madden, Christopher


    Children, older adults, disabled and special needs athletes, and female athletes who participate in outdoor and wilderness sports and activities each face unique risks. For children and adolescents traveling to high altitude, the preparticipation physical evaluation should focus on risk assessment, prevention strategies, early recognition of altitude-related symptoms, management plans, and appropriate follow-up. As the risk and prevalence of chronic disease increases with age, both older patients and providers need to be aware of disease and medication-specific risks relative to wilderness sport and activity participation. Disabled and special needs athletes benefit from careful pre-event planning for the potential medical issues and equipment modifications that may affect their health in wilderness environments. Issues that demand special consideration for female adventurers include pregnancy, contraceptive use, menses, and ferritin levels at altitude. A careful preparticipation evaluation that factors in unique, population- specific risks will help special populations stay healthy and safe on wilderness adventures. The PubMed and SportDiscus databases were searched in 2014 using both MeSH terms and text words and include peer-reviewed English language articles from 1977 to 2014. Additional information was accessed from Web-based sources to produce this narrative review on preparticipation evaluation for special populations undertaking wilderness adventures. Key words include children, adolescent, pediatric, seniors, elderly, disabled, special needs, female, athlete, preparticipiation examination, wilderness medicine, and sports. Copyright © 2015.

  18. Sustainable Livelihood Approach For Assessing Household Adoption To Eviction Mau Forest Kenya

    Directory of Open Access Journals (Sweden)

    Shadeya Akundabweni Juniour


    Full Text Available Studies have shown that there is a challenge in protecting both natural resources and livelihoods simultaneously. However little is known when considering the number of livelihoods strategies affected by the effect of conservation methods. This paper seeks to investigate the outcome of sustainable livelihood diversification by considering the number of strategies affected by eviction on households neighboring the boundaries of the Mau forest in Kenya. It is well understood that double sustainability is achieved when environmental protection of biodiversity is attained and the livelihood of households affected focuses on a pro-poor strategy at the same time. The study employs the Negative Binomial Regression and ANOVA to estimate the effect of being a victim of eviction on the number of alternative livelihood strategies. The results indicate a significant difference in diversification between households that were victims of eviction from non victims. Significantly evicted households dominantly engage in low income earning agricultural activities. The findings suggest that evicted households diversify but depend on forests and agricultural activities as a coping mechanism towards eviction. This information is important to policy makers in assisting to achieve double sustainability by looking at forest eviction conversation and household livelihood adoption needs.

  19. The implications of new forest tenure reforms and forestry property markets for sustainable forest management and forest certification in China. (United States)

    Chen, Juan; Innes, John L


    This study examines issues existing in the southern collective forests in China, particularly prior to the implementation of new forest tenure reforms, such as continued illegal logging and timber theft, inadequate availability of finance and inconsistent forest-related policies. Such problems are believed to be hindering the adoption of sustainable forest management (SFM) and forest certification by forest farmers in China. Two strategies were introduced by the Chinese government with the purpose of addressing these issues, namely forest tenure reforms and their associated supporting mechanism, forestry property markets. Through two case studies in southern China, we investigated the effectiveness of the two strategies as well as their implications for the adoption of SFM and forest certification. The two cases were Yong'an in Fujian province and Tonggu in Jiangxi province. Personal interviews with open-ended questions were conducted with small-scale forest farmers who had already benefited from the two strategies as well as market officers working for the two selected forestry property markets. The study identified eight issues constraining the potential adoption of SFM and certification in China, including limited finance, poorly developed infrastructure and transport systems, insecure forest tenures, inconsistent forest policies, low levels of awareness, illegal forest management practices, lack of local cooperative organizations, and inadequate knowledge and technical transfer. We found that the new forest tenure reforms and forestry property markets had generally fulfilled their original objectives and had the capacity to assist in addressing many of the issues facing forests prior to the reforms.

  1. Mountain Forests and Sustainable Development: The Potential for Achieving the United Nations' 2030 Agenda

    Directory of Open Access Journals (Sweden)

    Georg Gratzer


    Full Text Available The world is facing numerous and severe environmental, social, and economic challenges. To address these, in September 2015 the General Assembly of the United Nations adopted the resolution Transforming our World: The 2030 Agenda for Sustainable Development. The United Nations' 17 sustainable development goals (SDGs and their 169 targets are ambitious, broadly encompassing, and indivisible. They are intended to guide nations and communities toward attaining healthy and peaceful livelihoods free of poverty and hunger. Collectively the goals envision sound and safe environments, where global threats like climate change are successfully combated through both mitigation and adaptation. Agenda 2030 envisages sustainable production patterns with inclusive, effective economies and institutions. It is of specific relevance to mountain communities, where the population is predominantly rural and half of the rural inhabitants experience food insecurity and are often highly dependent on forest resources. Mountain forests also contribute to human welfare well beyond the local community: through functions such as climate and hydrological services provided at regional and global scales, and harvested commodities traded at multiple economic scales. In this introductory essay we argue that sustainable forest management in mountain areas disproportionately contributes to achieving the SDGs. We discuss (1 the potential of mountain forests to help achieve SDGs in mountainous regions and beyond, (2 the potential of the SDGs to help solve severe socioeconomic and ecological problems in forested mountain areas, and (3 challenges and opportunities associated with implementing the SDGs. We base our argumentation also on the 8 papers presented in this Focus Issue of Mountain Research and Development. Together, they establish a clear connection between sustainable use and protection of mountain forests and vital ecosystem services upon which many regions depend. We

  2. Where the wild things are: A research agenda for studying wildlife-wilderness relationship (United States)

    Schwartz, Michael K.; Hahn, Beth; Hossack, Blake R.


    We explore the connection between US designated wilderness areas and wildlife with the goal of establishing a research agenda for better understanding this complex relationship. Our research agenda has two components. The first, “wildlife for wilderness,” considers the impact of wildlife on wilderness character. Whereas studies show that wildlife is important in both the perception and actual enhancement of wilderness character, the context and particulars of this relationship have not been evaluated. For instance, is knowing that a rare, native species is present in a wilderness area enough to increase perceptions of naturalness (an important wilderness quality)? Or does the public need to observe the species or its sign (e.g., tracks) for this benefit? The second part of our research agenda, “wilderness for wildlife,” considers the types of research needed to understand the impact of wilderness areas on wildlife and biodiversity conservation. Several studies show the effect of one area being designated wilderness on one wildlife species. Yet, there has been no research that examines how the networks of wilderness areas in the National Wilderness Preservation System (NWPS) are used by a species or a community of species. Furthermore, we found no studies that focused on how the NWPS affects ecological or trophic interactions among species. We hope that by providing a research agenda, we can spur multiple lines of research on the topic of wildlife and wilderness.

    Energy Technology Data Exchange (ETDEWEB)

    Bravo, F.; Rodriguez, F.; Ordonez, C.


    Growth and yield models at different scales are useful tools for forest stake holders. Adequate simulation of forest stand conditions after different silviculture scenarios allows stake holders to adopt appropriate actions to maintain forest integrity while forest products and services are obtained to benefit society as a whole. SIMANFOR is a platform to simulate sustainable forest management alternatives, integrating different modules to manage forest inventories, simulate and project stand conditions and maintain systems security and integrity. SIMANFOR output is compatible with an Office environment (Microsoft or Open), allowing users to exchange data and files between SIMANFOR and their own software. New developments are being planned under a web 2.0 environment to take advantage of user input to improve SIMANFOR in the future. (Author) 9 refs.

  7. Experts’ Perceptions of the Effects of Forest Biomass Harvesting on Sustainability in the Alpine Region

    Directory of Open Access Journals (Sweden)

    Gianluca Grilli


    Full Text Available Background and Purpose: In the EU political agenda, the use of forest biomass for energy has grown rapidly and significantly, in order to mitigate carbon dioxide emissions and reduce the energy dependence on fossil fuels of European member countries. The target of the EU climate and energy package is to raise the share of renewable energy consumption produced from renewable resources to 20% in 2020 (Directive 2009/28/EC. With regards to biomass energy, the supply of forest wood biomass is expected to rise by 45% (reference period: 2006-2020, in response to increasing demand for renewable sources. The increase of forest biomass supply could have both positive and negative effects on several forest ecosystem services (ESs and local development. These effects should be assessed in a proper manner and taken into account when formulating management strategies. The aim of the paper is to assess the environmental, economic and social sustainability of forest biomass harvesting for energy, using the Figure of Merit (FoM approach. Materials and Methods: Sustainability was assessed through a set of four indicators: two focused on experts’ opinions regarding the effects of forest biomass harvesting and the other two focused on the cost-benefit analysis (potential energy obtained and costs for wood chips. The research was developed through four case studies located in the Alpine Region. A semi-structured questionnaire was administered face-to-face to 32 selected experts. The perceived effects of forest biomass harvesting for energy on ESs and local development were evaluated by experts using a 5-point Likert scale (from “quite negative effect” to “quite positive effect”. Results: All experts agree that forest biomass harvesting has a positive effect on forest products provision and local economic development (employment of local workforce, local entrepreneurship and market diversification, while the effects on other ESs are controversial (e

  10. ORGEST: Regional guidelines and silvicultural models for sustainable forest management

    Energy Technology Data Exchange (ETDEWEB)

    Piqué, Míriam; Vericat, Pau; Beltrán, Mario


    Aim of the study: To develop regional guidelines for sustainable forest management. Area of the study: Forests of Catalonia (NE Spain). Material and methods: The process of developing the forest management guidelines (FMG) started by establishing a thorough classification of forest types at stand level. This classification hinges on two attributes: tree species composition and site quality based on ecological variables, which together determine potential productivity. From there, the management guidelines establish certain objectives and silvicultural models for each forest type. The forest type classifications, like the silvicultural models, were produced using both existing and newly-built growth models based on data from the National Forest Inventory (NFI) and expert knowledge. The effort involved over 20 expert working groups in order to better integrate the expertise and vision of different sectorial agents. Main results: The FMG consist in quantitative silvicultural models that include typical silvicultural variables, technical descriptions of treatments and codes of good practice. Guidelines now cover almost all forest types in Catalonia (spanning up to 90% of the Catalan forest area). Different silvicultural models have been developed for pure and mixed stands, different site quality classes (2–3 classes per species), and even- and multi-aged stands. Research highlights: FMG: i) orient the management of private and public forests, (ii) provide a technical scaffold for efficient allocation/investment of public subsidies in forest management, and (iii) bridge forest planning instruments at regional (strategic-tactical) and stand (operational) level.

It is shown that presently – although given abundant resources – the share of heat and electricity from biomass is very minor. With the help of two IIASA models (G4M and BeWhere, future green-field bioenergy plants are identified in a geographically explicit way. Results indicate that by using 3.78 Mt (or 6.16 M m3, twice as much heat and electricity than is presently available from forest biomass could be generated. This amount corresponds to 3.3 % of the total annual wood removals or 12 % of the annually harvested firewood, or about 11 % of illegal logging. With this amount of wood, it is possible to provide an additional 444 thousand households with heat and 1.8 M households with electricity; and at the same time to replace 2.7 Mt of coal or 1.7 Mt of oil or 1.8 G m3 of natural gas, reducing emissions of greenhouse gases from burning fossil fuels by 716 Mt of CO2-equivalent per year. A multitude of co-benefits can be quantified for the socio-economic sector such as green jobs linked to bioenergy. The sustainable sourcing of woody biomass for bioenergy is possible as shown with the help of an online crowdsourcing tool for forest certification.

    Diego Matsvange


    Full Text Available Forest benefit analysis is vital in ensuring sustainable community-based natural resources management. Forest depletion and degradation are key issues in rural Zimbabwe and strategies to enhance sustainable forest management are continually sought. This study was carried out to assess the impact of forests on communities from Nyanga, Guruve and Zvimba districts of Zimbabwe. It is based on a Big Lottery Fund project implemented by Progressio-UK and Environment Africa. Itfocuses on identifying replicable community forest and landmanagement strategies and the level of benefits accruing to the community. Analysis of change was based on the Income and Food Security and Forest benefits, which also constitutes the tools used during the research. The study confirms the high rate of deforestation and the increased realisation by communities to initiate practical measures aimed at protecting and sustaining forest and land resources from which they derive economic and social benefits. The results highlight the value of community structures (Farmer Field Schools and Environmental Action Groups as conduits for natural resource management. The interconnectivity among forests, agricultural systems and the integral role of people are recognised as key to climate change adaptation.

    Linares Prieto, Ricardo; Avendano Reyes Jeimmy


    The handling and sustainable use of the forest ecosystems of the country is one of the purposes of the politicians from Colombia, in particular, and of the world in general; and the forest handling plans (PMF) they are constituted in one of the existent technical and legal instruments for its administration. However, the current national situation as for the use and conservation of the natural forests points out that the PMF is not completing its function and that they suffer of a hypothetical suitability lack for such ends. With base in the previous situation, it decided to carry out this investigation that was guided to evaluate and to determine the suitability of the PMF and the corresponding forest inventories, as instruments to plan and to carry out the handling and the use of the natural forests in Colombia, taking like case study; the Municipalities of Olaya Herrera, Francisco Pizarro, Mosquera, Roberto Payan and Magui, in the pacific coast of the Narino Department, that is one of the main areas of forest use in the country and supplying of an important volume of wood for the national industry, reason for which the use of the local forests is there the main productive activity of the black communities seated. The study was carried out during a lapse of six months, including two months of field work, in the mark of the Project: Application and Evaluation of Approaches and Indicators for the sustainable ordination of the natural forests, carried out under the auspices of the Ministry of the environment of Colombia and the International Organization of Tropical Wood - IOTW

    Carol Miller


    When the federal agencies established policies in the late 1960s and early 1970s to allow the use of natural fires in wilderness, they launched a natural fire management experiment in a handful of wilderness areas. As a result, wildland fire has played more of its natural role in wilderness than anywhere else. Much of what we understand about fire ecology comes from...

  1. Ecosystem services capacity across heterogeneous forest types: understanding the interactions and suggesting pathways for sustaining multiple ecosystem services. (United States)

    Alamgir, Mohammed; Turton, Stephen M; Macgregor, Colin J; Pert, Petina L


    As ecosystem services supply from tropical forests is declining due to deforestation and forest degradation, much effort is essential to sustain ecosystem services supply from tropical forested landscapes, because tropical forests provide the largest flow of multiple ecosystem services among the terrestrial ecosystems. In order to sustain multiple ecosystem services, understanding ecosystem services capacity across heterogeneous forest types and identifying certain ecosystem services that could be managed to leverage positive effects across the wider bundle of ecosystem services are required. We sampled three forest types, tropical rainforests, sclerophyll forests, and rehabilitated plantation forests, over an area of 32,000m(2) from Wet Tropics bioregion, Australia, aiming to compare supply and evaluate interactions and patterns of eight ecosystem services (global climate regulation, air quality regulation, erosion regulation, nutrient regulation, cyclone protection, habitat provision, energy provision, and timber provision). On average, multiple ecosystem services were highest in the rainforests, lowest in sclerophyll forests, and intermediate in rehabilitated plantation forests. However, a wide variation was apparent among the plots across the three forest types. Global climate regulation service had a synergistic impact on the supply of multiple ecosystem services, while nutrient regulation service was found to have a trade-off impact. Considering multiple ecosystem services, most of the rehabilitated plantation forest plots shared the same ordination space with rainforest plots in the ordination analysis, indicating that rehabilitated plantation forests may supply certain ecosystem services nearly equivalent to rainforests. Two synergy groups and one trade-off group were identified. Apart from conserving rainforests and sclerophyll forests, our findings suggest two additional integrated pathways to sustain the supply of multiple ecosystem services from a

  5. Firewood harvest from forests of the Murray-Darling Basin, Australia. Part 1: Long-term, sustainable supply available from native forests

    International Nuclear Information System (INIS)

    West, P.W.; Cawsey, E.M.; Stol, J.; Freudenberger, D.


    The Murray-Darling Basin is a 1 million km 2 agricultural region of south-eastern Australia, although 29% of it retains native forests. Some are mallee eucalypt types, whilst the 'principal' types are dominated mainly by other eucalypt species. One-third of the 6-7 million oven-dry tonne of firewood burnt annually in Australia is obtained from these forests, principally through collection of coarse woody debris. There are fears that removal of this debris may prejudice the floral and faunal biodiversity of the Basin. The present work considers what silvicultural management practices will allow the long-term maintenance of the native forests of the Basin and their continued contribution to its biodiversity. It then estimates that the maximum, long-term, annual, sustainable yield of firewood which could be harvested, by collection of coarse woody debris, from principal forest types of the Basin would be 10 million oven-dry tonne yr -1 . An alternative, harvest of firewood from live trees by thinning the principal forests and clear-felling mallee forests, would be able to supply 2.3 million tonne yr -1 sustainably. Whilst coarse woody debris harvests could supply far more than the present demand for firewood from the Basin, they would lead to substantial reductions of the debris remaining in the forests; this may be detrimental to biodiversity maintenance. Live tree harvest does not lead to this problem, but would barely be able to supply existing firewood demand

  8. Predicted effects of prescribed burning and harvesting on forest recovery and sustainability in southwest Georgia, USA. (United States)

    Garten, Charles T


    A model-based analysis of the effect of prescribed burning and forest thinning or clear-cutting on stand recovery and sustainability was conducted at Fort Benning, GA, in the southeastern USA. Two experiments were performed with the model. In the first experiment, forest recovery from degraded soils was predicted for 100 years with or without prescribed burning. In the second experiment simulations began with 100 years of predicted stand growth, then forest sustainability was predicted for an additional 100 years under different combinations of prescribed burning and forest harvesting. Three levels of fire intensity (low, medium, and high), that corresponded to 17%, 33%, and 50% consumption of the forest floor C stock by fire, were evaluated at 1-, 2-, and 3-year fire return intervals. Relative to the control (no fire), prescribed burning with a 2- or 3-year return interval caused only a small reduction in predicted steady state soil C stocks (burns did adversely impact forest recovery and sustainability (after harvesting) on less sandy soils, but not on more sandy soils that had greater N availability. Higher intensity and frequency of ground fires increased the chance that tree biomass would not return to pre-harvest levels. Soil N limitation was indicated as the cause of unsustainable forests when prescribed burns were too frequent or too intense to permit stand recovery.

    , tree mortality has been observed also in stands on favourable soils (rusty brown forest soil, brown earth, lessivated brown forest soil) because these soil sites can only mitigate the damage of extremes. Consequently, there is ongoing change of site conditions that are important for the sustainable forest management planning. Therefore it is an urgent need to rethink regulations considering the changing climate and soil conditions in order to decide about sustainable tree species preference and to maintain forest cover.

  12. Multi-Stakeholder Collaboration in Russian and Swedish Model Forest Initiatives: Adaptive Governance Toward Sustainable Forest Management?

    Directory of Open Access Journals (Sweden)

    Marine Elbakidze


    Full Text Available Building the adaptive capacity of interlinked social and ecological systems is assumed to improve implementation of sustainable forest management (SFM policies. One mechanism is collaborative learning by continuous evaluation, communication, and transdisciplinary knowledge production. The Model Forest (MF concept, developed in Canada, is intended to encourage all dimensions of sustainable development through collaboration among stakeholders of forest resources in a geographical area. Because the MF approach encompasses both social and ecological systems, it can be seen as a process aimed at improving adaptive capacity to deal with uncertainty and change. We analyzed multi-stakeholder approaches used in four MF initiatives representing social-ecological systems with different governance legacies and economic histories in the northwest of the Russian Federation (Komi MF and Pskov MF and in Sweden (Vilhelmina MF and the Foundation Säfsen Forests in the Bergslagen region. To describe the motivations behind development of the initiative and the governance systems, we used qualitative open-ended interviews and analyzed reports and official documents. The initial driving forces for establishing new local governance arrangements were different in all four cases. All MFs were characterized by multi-level and multi-sector collaboration. However, the distribution of power among stakeholders ranged from clearly top down in the Russian Federation to largely bottom up in Sweden. All MF initiatives shared three main challenges: (a to develop governance arrangements that include representative actors and stakeholders, (b to combine top-down and bottom-up approaches to governance, and (c to coordinate different sectors' modes of landscape governance. We conclude that, in principle, the MF concept is a promising approach to multi-stakeholder collaboration. However, to understand the local and regional dimensions of sustainability, and the level of adaptability

  13. Trading Natural Riparian Forests for Urban Shelterbelt Plantations—A Sustainability Assessment of the Kökyar Protection Forest in NW China

    Directory of Open Access Journals (Sweden)

    Siegmund Missall


    Full Text Available Cities at the fringe of the Taklimakan desert in NW China are prone to dust and sand storms with serious consequences for human well-being. The Kökyar Protection Forest was established in the 1980s as an ecological engineering project with the intent of protecting the city of Aksu, NW China, from these impacts. It is designed as a combination of poplar shelterbelts and orchards, irrigated by river water from the Aksu River, the main tributary of the Tarim River. Prevalent literature describes it as an afforestation project for combatting desertification with manifold positive effects for the economic, social, and environmental dimension of sustainable development. This paper sets out to challenge these claims by a sustainability assessment in which the plantation is examined from a broader perspective, embedding it to the wider context of social and environmental problems in South Xinjiang. Methods comprise evapotranspiration calculations, interviews, a socioeconomic household survey, stakeholder dialogues, and literature research. Results affirm its economic sustainability, but see a mixed record for the social sphere. From the nature conservation point of view, it has to be classified as unsustainable because its high irrigation water consumption results in the downstream desiccation and desertification of natural riparian forests along the Tarim River, causing a forest loss in the downstream area twice the size of the forest gain in the upstream area. There is a trade-off between artificial shelterbelt plantations for urban ecosystem services on the one hand side, and natural riparian forests and their biodiversity on the other hand side. The paper recommends restricting agricultural extension, and using locally adapted less water consuming agroforestry schemes to protect urban dwellers from dust stress.

  5. Identification of Appropriate Biodiversity Indicators for Ecologically Sustainable Forest Management at National Level

    International Nuclear Information System (INIS)

    Tolunay, A.; Akyol, A.


    Sustainable forest management (SFM) practices have started in 1999 in Turkey. A set of criteria and indicators, composed by the General Directorate of Forestry (GDF) on the basis of the criteria and indicators defined in the Pan-European and Near Eastern Processes, was enquired via a survey to serve this purpose. GDF tested the sustainability under the following titles: Situation of forest resources, biodiversity, health and vitality, production capacity and functions, protective functions and environmental and socio-economic functions. There were problems in identification and definition of SFM criteria and indicators. Biological diversity indicators has been selected, described and developed in this study. At this phase, the survey was completed upon receiving the views of the scientists interested in different dimensions of this topic as well as the views of other interest groups affiliated with forestry. As a result, there were 13 indicators that may be used as the basis of a regional or forest management unit level for the purpose of protecting, developing and maintaining biodiversity. Furthermore, these indicators are instruments, which may easily be used by relevant decision-makers in the management of forest resources in a more effective and productive manner. (author)

  10. Rural aquaculture as a sustainable alternative for forest conservation in the Monarch Butterfly Biosphere Reserve, Mexico. (United States)

    López-García, José; Manzo-Delgado, Lilia L; Alcántara-Ayala, Irasema


    Forest conservation plays a significant role in environmental sustainability. In Mexico only 8.48 million ha of forest are used for conservation of biodiversity. Payment for Environmental Services in the Monarch Butterfly Biosphere Reserve, one of the most important national protected areas, contributes to the conservation of these forests. In the Reserve, production of rainbow trout has been important for the rural communities who need to conserve the forest cover in order to maintain the hibernation cycle of the butterfly. Aquaculture is a highly productive activity for these protected areas, since it harnesses the existing water resources. In this study, changes from 1999 to 2012 in vegetation and land-use cover in the El Lindero basin within the Reserve were evaluated in order to determine the conservation status and to consider the feasibility of aquaculture as a means of sustainable development at community level. Evaluation involved stereoscopic interpretation of digital aerial photographs from 1999 to 2012 at 1:10,000 scale, comparative analysis by orthocorrected mosaics and restitution on the mosaics. Between 1999 and 2012, forested land recovered by 28.57 ha (2.70%) at the expense of non-forested areas, although forest degradation was 3.59%. Forest density increased by 16.87%. In the 46 ha outside the Reserve, deforestation spread by 0.26%, and land use change was 0.11%. The trend towards change in forest cover is closely related to conservation programmes, particularly payment for not extracting timber, reforestation campaigns and surveillance, whose effects have been exploited for the development of rural aquaculture; this is a new way to improve the socio-economic status of the population, to avoid logging and to achieve environmental sustainability in the Reserve.

  12. Sustainability and economics: The Adirondack Park experience, a forest economic-ecological model, and solar energy policy (United States)

    Erickson, Jon David

    The long-term sustainability of human communities will depend on our relationship with regional environments, our maintenance of renewable resources, and our successful disengagement from nonrenewable energy dependence. This dissertation investigates sustainability at these three levels, following a critical analysis of sustainability and economics. At the regional environment level, the Adirondack Park of New York State is analyzed as a potential model of sustainable development. A set of initial and ongoing conditions are presented that both emerge from and support a model of sustainability in the Adirondacks. From these conditions, a clearer picture emerges of the definition of regional sustainability, consequences of its adoption, and lessons from its application. Next, an economic-ecological model of the northern hardwood forest ecosystem is developed. The model integrates economic theory and intertemporal ecological concepts, linking current harvest decisions with future forest growth, financial value, and ecosystem stability. The results indicate very different economic and ecological outcomes by varying opportunity cost and ecosystem recovery assumptions, and suggest a positive benefit to ecological recovery in the forest rotation decision of the profit maximizing manager. The last section investigates the motives, economics, and international development implications of renewable energy (specifically photovoltaic technology) in rural electrification and technology transfer, drawing on research in the Dominican Republic. The implications of subsidizing a photovoltaic market versus investing in basic research are explored.

    The historic Wilderness Act celebrated its 50th anniversary in 2014, and wilderness social science shared a similar legacy. As paradoxical as it might seem, humans are an important part of wilderness, helping to define the very concept and representing an important component of wilderness use and management. Much of the past five decades of wilderness-related...

    Sarah K. Mincey; Miranda Hutten; Burnell C. Fischer; Tom P. Evans; Susan I. Stewart; Jessica M. Vogt


    A decline in urban forest structure and function in the United States jeopardizes the current focus on developing sustainable cities. A number of social dilemmas—for example, free-rider problems—restrict the sustainable production of ecosystem services and the stock of urban trees from which they flow. However, institutions, or the rules, norms, and strategies that...

  15. Damned if you do, damned if you do not - Reduced Climate Impact vs. Sustainable Forests in Sweden

    International Nuclear Information System (INIS)

    Geijer, Erik; Bostedt, Goeran; Braennlund, Runar


    The main objective of this paper is to analyze the potential goal conflict between two of Sweden's environmental objectives: Sustainable Forests and Reduced Climate Impact - or, more precisely, the conflict between forest conservation and the supply of wood fuel. To accomplish this, we use a forest sector model that includes the suppliers and major users of roundwood. The econometric results, based on a data set that spans 40 years, show that all the own price elasticities have the expected signs. Among the three forestry products, the supply and (long-term) demand of forest fuel seems to be most sensitive to a price change. In a second step, the estimated model is used to simulate the effect of increased forest conservation - the Sustainable Forest objective - on the supply of wood fuel. If oil is used as a substitute, Swedish emissions of greenhouse gases will increase by almost 0.92 percent, which indicates a clear conflict with the Reduced Climate Impact objective. (author)

  18. An outlook for sustainable forest bioenergy production in the Lake States

    International Nuclear Information System (INIS)

    Becker, Dennis R.; Skog, Kenneth; Hellman, Allison; Halvorsen, Kathleen E.; Mace, Terry


    The Lake States region of Minnesota, Wisconsin and Michigan offers significant potential for bioenergy production. We examine the sustainability of regional forest biomass use in the context of existing thermal heating, electricity, and biofuels production, projected resource needs over the next decade including existing forest product market demand, and impacts on price and feasibility. Assuming $36 per dry tonne at roadside, 4.1 million dry tonnes of forest biomass could be available region-wide. However, less is likely available due to localized environmental and forest cover type constraints, and landowner willingness to harvest timber. Total projected demand of 5.7 million dry tonnes, based on current and announced industry capacity, exceeds estimates of biomass availability, which suggests that anticipated growth in the forest-based bioeconomy may be constrained. Attaining projected demand will likely require a combination of higher cost feedstocks, integration of energy and non-energy uses, and careful management to meet environmental constraints. State distinctions in biomass harvest guidelines and the propensity for third-party forest certification will be critical in providing environmental safeguards. The cumulative effect of policy initiatives on biomass competition are discussed in the context of an emerging Lake States bioeconomy.

  20. Productivity assessment of timber harvesting techniques for supporting sustainable forest management of secondary Atlantic Forests in southern Brazil

    Directory of Open Access Journals (Sweden)

    Pedro Caldas Britto


    Full Text Available The Atlantic Forest in southern Brazil has been subject to overexploitation in the past prompting the formulation of a rigorous conservation orientated policy by the government including a strict ban of timber harvesting. In the region, the forestland is owned by farmers. The economic value of the forest is rather limited for those farmers, because of the prohibition of commercial timber harvesting as a source of income. Sustainable forest management systems can offer great potential as new income opportunities for land holders, and further actively support the process of ecosystem rehabilitation and protection for these ecosystems. Yet, successful implementation of such sustainable management systems requires feasible and adapted timber harvesting systems. In order to develop such harvesting systems, a regional comparative case study was conducted at a typical smallholder forestry venture with the objective to analyze and evaluate harvesting methods supporting sustainable management of the Atlantic Forest. This study assessed production rates and associated costs of a common conventional timber harvesting method (CM and a proposed alternative method (AM. CM was performed by a selected, typical forest landowner who had only basic training in chainsaw operations, but 20 years of experience at the wood yard of his small sawmill. In contrast, the AM employed a professional chainsaw operator from the Amazon forest, trained and experienced in reduced impact logging techniques using state of the art equipment, supplemented by a snatch block and a skidding cone for improved extraction. Time study based models identified tree volume, winching distance and skidding distance to the landing as the most significant independent variables affecting productivity. Total net productivity ranged from 4.9 m³ PMH0-1 for CM to 3.1 m³ PMH0-1 for AM. Corresponding gross-productivity ranged from 3.0 m³ SMH-1 to 1.9 m³ SMH-1 with an overall mean utilization rate of

  1. Sustainable management in crop monocultures: the impact of retaining forest on oil palm yield. (United States)

    Edwards, Felicity A; Edwards, David P; Sloan, Sean; Hamer, Keith C


    Tropical agriculture is expanding rapidly at the expense of forest, driving a global extinction crisis. How to create agricultural landscapes that minimise the clearance of forest and maximise sustainability is thus a key issue. One possibility is protecting natural forest within or adjacent to crop monocultures to harness important ecosystem services provided by biodiversity spill-over that may facilitate production. Yet this contrasts with the conflicting potential that the retention of forest exports dis-services, such as agricultural pests. We focus on oil palm and obtained yields from 499 plantation parcels spanning a total of ≈23,000 ha of oil palm plantation in Sabah, Malaysian Borneo. We investigate the relationship between the extent and proximity of both contiguous and fragmented dipterocarp forest cover and oil palm yield, controlling for variation in oil palm age and for environmental heterogeneity by incorporating proximity to non-native forestry plantations, other oil palm plantations, and large rivers, elevation and soil type in our models. The extent of forest cover and proximity to dipterocarp forest were not significant predictors of oil palm yield. Similarly, proximity to large rivers and other oil palm plantations, as well as soil type had no significant effect. Instead, lower elevation and closer proximity to forestry plantations had significant positive impacts on oil palm yield. These findings suggest that if dipterocarp forests are exporting ecosystem service benefits or ecosystem dis-services, that the net effect on yield is neutral. There is thus no evidence to support arguments that forest should be retained within or adjacent to oil palm monocultures for the provision of ecosystem services that benefit yield. We urge for more nuanced assessments of the impacts of forest and biodiversity on yields in crop monocultures to better understand their role in sustainable agriculture.

  2. Sustaining Jamaica's forests: The protected areas resource conservation project (United States)

    Berke, Philip R.; Beatley, Timothy


    This study examines Jamaica's attempt to protect a tropical forest reserve. The biophysical setting, and the types and magnitude of forest development pressures are reviewed. Next, Jamaica's approach to developing new land-use strategies and compatible environmental protection and economic development programs are examined. Finally, the practical and theoretical implications by which institutions can be designed to encourage planning for sustainable development are reviewed. The implications suggest how to provide an appropriate mix of cooperation and market competition, by which people acting in their own interests accomplish socially equitable economic development, while protecting the environment for the benefit of future generations. The experience illustrates that effective long-term protection of natural areas requires the building of local relationships and support, the development of local economic activities supportive of conservation, the defining of clear boundaries, and significant monitoring and enforcement. Long-term protection of the Blue and John Crow mountains, and other important natural areas of Jamaica, will also require the development of a workable and enforceable system of land-use planning for the island, and adjustments to the economic incentive structure so that sustainable, nonextractive uses of natural capital are placed on equal footing with other economic uses (e.g., coffee production).

  3. Wilderness experience in Rocky Mountain National Park 2002: Report to RMNP (United States)

    Schuster, Elke; Johnson, S. Shea; Taylor, Jonathan G.


    Approximately 250,000 acres of backcountry in Rocky Mountain National Park (RMNP or the Park) may be designated as wilderness use areas in the coming years. Currently, over 3 million people visit RMNP each year; many drive through the park on Trail Ridge Road, camp in designated campgrounds, or hike in front-country areas. However, visitors also report much use of backcountry areas that are not easily accessible by roads or trails. Use of the backcountry is growing at RMNP and is accompanied by changing visitor expectations and preferences for wilderness management. For these reasons it is of great importance for the Park to periodically assess what types of environments and conditions wilderness users seek, to help them facilitate a quality wilderness experience.

  11. Managing Sustainability of Fennoscandian Forests and Their Use by Law and/or Agreement: For Whom and Which Purpose?

    Directory of Open Access Journals (Sweden)

    Diana Tuomasjukka


    Full Text Available Sustainability and sustainable behaviour is of crucial importance in the management of Fennoscandian forests and forest-related industries. This paper reviews a number of voluntary instruments, which aim at promoting or assessing sustainability impacts at different levels. The multitude of available instruments brings confusion in practice, where companies, consumers and investors meet legal and different voluntary regulatory and non-regulatory instruments. The practical suitability and covered sustainability dimension for each instrument is reviewed with an analysis of strengths, weaknesses, actors and purposes for assessing different aspects of sustainability. Each of them is compared against the other in an overview about which sustainability dimensions they cover (workplace, human rights, community, market place, environment, economy. Results highlight covered, overlapping and missing aspects for each approach and how they can support or reinforce each other. Special attention is given to current approaches in impact assessment, particularly on their areas of application (companies, NGOs, products, operations, production practices, etc., and recommendations for supplementing it with sustainability impact assessment.

  5. Sustainable forest management: a challenging task in the siran watershed of district Mansehra in the NWFP of Pakistan

    International Nuclear Information System (INIS)

    Khurshid, M.


    Forests play an important socio-economic and environmental role on earth. Exploitation of forest resources within the carrying capacity of the natural ecosystem has always ensured their sustainability but in recent decades man has overexploited these resources to meet various needs. Pakistan with only 4.8% of its total land area under forests was also experiencing unsustainable forest management. In the Siran Watershed of District Mansehra in the North West Frontier Province (NWFP) of Pakistan, forests were exploited to meet not only the domestic and commercial wood-fuel needs but also timber needs of the local and external markets. Moreover, the local communities as a source of income generation have also used forest resources to increase their cash income earnings. Analysis of time series forest cover change in the past three decades was done in three adjacent sub-watersheds having different property right regimes. The GIS based spatial analysis showed that despite government efforts to conserve these forests, 75% of the forests were completely converted either into regeneration area (34%) or barren areas (41 %) during the past three decades. The Protected Forests have lost 41 % of its cover and the Guzara Forests 34%. Results show that the forest degradation stress has greatly increased in the eighties and afterwards. Using stakeholder analysis the key wood demanding stake holders in terms of their wood demand state were the local communities, the external commercial timber consumers, tobacco growers and Afghan refugees. The wood supplies stake holders were the Forest Department that controls the Common Pool Forests (CPF), the Forest Development Corporation (FDC), the Forest Cooperative Societies (FCS) and the farm foresters. Analysis of the cause effect relationship of the system shows that the pressure factors of increased wood demand by various stake holders coupled with the enabling factors of the market failure, government failure and institutional failure

  6. Adaptive genetic potential of coniferous forest tree species under climate change: implications for sustainable forest management (United States)

    Mihai, Georgeta; Birsan, Marius-Victor; Teodosiu, Maria; Dumitrescu, Alexandru; Daia, Mihai; Mirancea, Ionel; Ivanov, Paula; Alin, Alexandru


    Mountain ecosystems are extremely vulnerable to climate change. The real potential for adaptation depends upon the existence of a wide genetic diversity in trees populations, upon the adaptive genetic variation, respectively. Genetic diversity offers the guarantee that forest species can survive, adapt and evolve under the influence of changing environmental conditions. The aim of this study is to evaluate the genetic diversity and adaptive genetic potential of two local species - Norway spruce and European silver fir - in the context of regional climate change. Based on data from a long-term provenance experiments network and climate variables spanning over more than 50 years, we have investigated the impact of climatic factors on growth performance and adaptation of tree species. Our results indicate that climatic and geographic factors significantly affect forest site productivity. Mean annual temperature and annual precipitation amount were found to be statistically significant explanatory variables. Combining the additive genetic model with the analysis of nuclear markers we obtained different images of the genetic structure of tree populations. As genetic indicators we used: gene frequencies, genetic diversity, genetic differentiation, genetic variance, plasticity. Spatial genetic analyses have allowed identifying the genetic centers holding high genetic diversity which will be valuable sources of gene able to buffer the negative effects of future climate change. Correlations between the marginal populations and in the optimal vegetation, between the level of genetic diversity and ecosystem stability, will allow the assessment of future risks arising from current genetic structure. Therefore, the strategies for sustainable forest management have to rely on the adaptive genetic variation and local adaptation of the valuable genetic resources. This work was realized within the framework of the project GENCLIM (Evaluating the adaptive potential of the main

The fact the strategic in implementing the REDD+ and carbon trading in MU level is still lack of pilot project and methodology. Therefore, some scenarios must be developed and tested to find out the best potential of carbon credit in MU level. The objectives of the research were: to calculate carbon credit in some SFM scenarios, to analyze of carbon trading project feasibility, and to determine carbon stock recovery period of logged over area (LOA. The result revealed that carbon stock and carbon credit of LOA was affected by timber cutting intensity.  The 6th scenario with lowest annual allowable cutting (AAC obtained greater carbon credit and profit coming from timber harvesting income and carbon trading. In other hand, this scenario has shortest duration of carbon stock recovery period (27 years and shorter than its cutting cycle.  In this case, the MU has to recalculate and to decrease its AAC to have highest benefits from carbon trading in the same cutting cycle period.  It will provide double benefits from carbon trading, those are contribution in achieving the SFM purposes (production, ecology, social and climate change mitigation.Keywords: sustainable forest management, AAC, carbon stocks, recovery period, carbon trading

  8. Long photoperiods sustain high pH in Arctic kelp forests. (United States)

    Krause-Jensen, Dorte; Marbà, Núria; Sanz-Martin, Marina; Hendriks, Iris E; Thyrring, Jakob; Carstensen, Jacob; Sejr, Mikael Kristian; Duarte, Carlos M


    Concern on the impacts of ocean acidification on calcifiers, such as bivalves, sea urchins, and foraminifers, has led to efforts to understand the controls on pH in their habitats, which include kelp forests and seagrass meadows. The metabolism of these habitats can lead to diel fluctuation in pH with increases during the day and declines at night, suggesting no net effect on pH at time scales longer than daily. We examined the capacity of subarctic and Arctic kelps to up-regulate pH in situ and experimentally tested the role of photoperiod in determining the capacity of Arctic macrophytes to up-regulate pH. Field observations at photoperiods of 15 and 24 hours in Greenland combined with experimental manipulations of photoperiod show that photoperiods longer than 21 hours, characteristic of Arctic summers, are conducive to sustained up-regulation of pH by kelp photosynthesis. We report a gradual increase in pH of 0.15 units and a parallel decline in pCO 2 of 100 parts per million over a 10-day period in an Arctic kelp forest over midsummer, with ample scope for continued pH increase during the months of continuous daylight. Experimental increase in CO 2 concentration further stimulated the capacity of macrophytes to deplete CO 2 and increase pH. We conclude that long photoperiods in Arctic summers support sustained up-regulation of pH in kelp forests, with potential benefits for calcifiers, and propose that this mechanism may increase with the projected expansion of Arctic vegetation in response to warming and loss of sea ice.

  10. Trade-offs between ecosystem services and alternative pathways toward sustainability in a tropical dry forest region

    Directory of Open Access Journals (Sweden)

    Francisco Mora


    Full Text Available The design of strategies aimed at sustainable resource management requires an understanding of the trade-offs between the ecosystem services at stake, to determine appropriate ways in which to navigate them. We assess trade-offs between forage production for cattle ranching and the maintenance of carbon stocks or tree diversity in a Mexican tropical dry forest. Trade-offs between pairs of services were assessed by identifying their efficiency frontiers at both site and landscape scales. We also estimated service outcomes under current and hypothetical land-management conditions. We found stark trade-offs between fodder and carbon stocks and between fodder and tree species richness at the site scale. At the landscape scale, the efficiency frontier was concave, with a much less pronounced trade-off in the fodder-species richness case. Our estimates of current service supply levels showed a reduction of 18-21% for C stock and 41-43% for fodder biomass, relative to the maximum feasible values along the efficiency frontier. Choice of the optimum management strategy to reduce such inefficiency depended on deforestation level: secondary forest regeneration was most suitable when deforestation is low, whereas increased fodder productivity in the pastures is best when deforestation is high. Pasture enrichment with forage trees and secondary forest growth are potential management alternatives for achieving sustainability given the range of enabling ecological factors and to balance ecological and social sustainability given the requirements and preferences of local stakeholders. Given that analogous trade-offs are found across the tropics, this work contributes to reconciling tropical forest maintenance and its use for sustainable rural livelihoods.

  11. Future Forests. Sustainable Strategies under Uncertainty and Risk

    Energy Technology Data Exchange (ETDEWEB)


    Climate change, globalization, and increased consumption of materials and energy leads to higher pressure on forest resources. The task of intensifying forestry to produce more timber, paper, and energy, while at the same time ensuring ecosystem services, such as biodiversity and recreation, is a complex one. Difficult decisions have to be made if we are to strike a balance between these demands. These decisions have to be supported by scientifically-based land-use strategies to deal with tradeoffs on different scales. The vision of Future Forests is to take a significant step forward in this complicated task. The Program has a long-term perspective (50-100 years) and will consider changes in climate, as well as global and market development as major factors likely to have a strong influence on forest management and forest landscapes in the future. In this context, uncertainties, vulnerability, and the adaptive capacity of social-ecological systems must also be considered. The Program's promise to society is: Future Forests will create knowledge and tools to enable sustainable decisions for the future of one of our most important resources - our forests. To fulfill this promise, the Program has the ambition to constitute a platform where researchers from different disciplines, and practitioners from several sectors, can interact. The program will combine empirical research with modeling, scenario analysis, and synthesis work in order to produce excellent science and applications. Much of the multidisciplinary research performed in the Program will be done in the Component Projects. These research groups will be responsible for producing detailed, high quality scientific results that can both be incorporated into the scenarios and be directly relevant for our stakeholders. The Center for Forest System Analyses and Synthesis (ForSA) will form a unifying force in Future Forests. The main goal for this center is to develop skills in scenario analyses and to

    “Social conditions in wilderness” refers to all aspects of human use of the wilderness that pose the possibility of impact to the resource and visitor experiences. The reasons for monitoring (1) use levels and use trends (including characteristics of use and users) and (2) the quality of the recreation experiences provided (ability to provide naturalness, privacy, and...

  14. A Cross-Cultural Exploration of 'Wild' in Wilderness Therapy: Canada, Norway and Australia (United States)

    Harper, Nevin J.; Gabrielsen, Leiv E.; Carpenter, Cathryn


    This paper addresses pluralistic understandings of wilderness in the context of wilderness therapy (WT). The term wilderness perpetuates a modern worldview of place that beyond 'civilisation' exists an environment defined by risk, fear and an unpredictable nature. WT utilises outdoor travel and living practices during therapeutic intervention and…

The results of this simulation test suggest that levels of...

  1. The Black Rock Forest Consortium: A narrative (United States)

    Buzzetto-More, Nicole Antoinette

    The Black Rock Forest is a 3,785-acre wilderness area whose richly forested landscape represents the splendor of the Hudson Valley Region of New York State. Although originally intended to become the home of wealthy banker James Stillman, it was his son Ernest whose love of conservation caused him to embrace the then new and revolutionary practice of sustainable forestry and establish Black Rock in 1928. Due to Ernest Stillman's foresight, the property was protected from development and bequeathed to Harvard University following his death for the establishment of an experimental forest. The modern environmental movement in America began when the Black Rock Forest was threatened with development by Consolidated Edison, and the people of the surrounding community banded together, battling tirelessly for over 17 years to stop the degradation of this historic forest. The outcome of this crusade marked a hallmark win for the environment leaving an illustrious and inveterate legacy. The campaign resulted in the watershed legislation the National Environmental Policy Act, the formation of several environmental advocacy groups, the creation of the Council on Environmental Quality of the Executive Office of the President, as well as set a precedent for communities to initiate and win cases against major corporations in order to safeguard natural resources. In the midst of the controversy it became apparent that alternative futures for the Forest needed to be explored. As a result of a committee report and one man's vision, the idea emerged to create a consortium that would purchase and steward the Forest. With a formation that took nearly fifteen years, the Black Rock Forest Consortium was formed, a unique amalgamation of K--12 public and private schools, colleges and universities, and science and cultural centers that successfully collaborate to enhance scientific research, environmental conservation, and education. The Consortium works to bridge the gaps between learners

  5. The relationships of forest biodiversity and rattan jernang (Deamonorops draco sustainable harvesting by Anak Dalam tribe in Jambi, Sumatra

    Directory of Open Access Journals (Sweden)


    Full Text Available Adiwibowo A, Sulasmi IS. 2012. Relationships of forest biodiversity and rattan jernang (Deamonorops draco sustainable harvesting by Anak Dalam tribe in Jambi, Sumatra. Biodiversitas 13: 00-00. Conservation of tropical trees can be achieved if supported by the sustainable use of forest by community live nearby through harvesting of non timber woods, for instance rattan. Furthermore, rattan jernang individuals and trees have significant associations. Therefore, objective of this paper is to investigate the utilization of rattan jernang (Deamonorops draco Wild related to the forest tree biodiversity by Anak Dalam tribe in several villages in Jambi, Sumatra. The study has identified that populations of Deamonorops draco were varied among villages, ranged from 40 to 71 clumps in the forests and up to 500 clumps in plantations. Moreover, 73 individual trees consisted of 32 species were identified as rattan host and conserved by the community. Dialium platyespalyum. Quercus elmeri, and Adinandra dumosa were rattan host trees with the highest populations. Meanwhile, a biodiversity of non-host trees consisted of 30 individual trees from 16 species. Interviews revealed that traditional harvesters have acknowledged that trees have significant important ecological roles for the rattan livelihood and therefore it is very important to conserve the forests for the sustainability of harvest in the future. Furthermore, to secure the availability of rattan, the traditional harvesters had started rattan plantation.

  7. Socioeconomic Collapse of Rural Areas, Atlantic Forest Transition and Sustainability (United States)

    Silva, R. F. B. D.; Batistella, M.; Moran, E. F.


    Centuries of human pressure over the Atlantic Forest has led the biome to encompass only 11.7 percent of forest remnants. On the other hand, natural regeneration has explained forest cover increase in specific regions since the 1960s as an outcome of land use policies, environmental legislation, agricultural modernization, economic development, and landscape biophysical conditions. We analyze Forest Transition (FT) pathways for the Paraíba Valley region, São Paulo State, Brazil looking for more sustainable relationships between land use and natural land cover. During the 18th and 19th centuries, the Valley's farms were responsible for providing the largest portion of the state's wealth. Nowadays, the Valley contributes with only 6% to the state's gross product and the share of rural activities is now insignificant. Between 1962 and 2011, forest cover area increased from 225 to 446 thousand hectares. Rural household survey was conducted in three municipalities (n=90, thirty in each municipality). To select the municipalities among the thirty-four present in the Paraíba Valley, we applied the modified Thompson Tau technique to detect outlier values for three selected variables: natural forest cover, eucalyptus plantation cover, and municipal revenue. The outliers were discharged and the municipality with the best performance (maximum value) for each variable was selected. Based on the rural household surveys and GIS analysis of satellite imagery classifications, topography and hydrology variables, we conclude that the diminished land use pressure in the Paraíba Valley is allowing the regeneration of forest cover. Over the observed period, the FT was strongly influenced by the unsuitable topography for agriculture (steep slopes) and the economic urban development since the 1960s. However, more recently (2000s), FT is more affected by the vicinity of eucalyptus plantations, the active role of local communities denouncing illegal environmental threats (e

  9. Black Truffle Harvesting in Spanish Forests: Trends, Current Policies and Practices, and Implications on its Sustainability (United States)

    Garcia-Barreda, Sergi; Forcadell, Ricardo; Sánchez, Sergio; Martín-Santafé, María; Marco, Pedro; Camarero, J. Julio; Reyna, Santiago


    The European black truffle is a mycorrhizal fungus native to Spanish Mediterranean forests. In most Spanish regions it was originally commercially harvested in the second half of the 20th century. Experts agree that wild truffle yields suffered a sharp decline during the 1970s and 1980s. However, official statistics for Spanish harvest are scarce and seemingly conflicting, and little attention has been paid to the regime for the exploitation of truffle-producing forests and its implications on the sustainability of this resource. Trends in harvest from 1969 to 2013 and current harvesting practices were analyzed as a case study, taking into account that Spain is a major truffle producer worldwide, but at the same time truffles have only recently been exploited. The available statistical sources, which include an increasing proportion of cultivated truffles since the mid-1990s, were explored, with estimates from Truffle Harvesters Federation showing higher consistency. Statistical sources were then compared with proxies for wild harvest (rents from truffle leases in public forests) to corroborate time trends in wild harvesting. Results suggest that black truffle production is recovering in recent years thanks to plantations, whereas wild harvest is still declining. The implications of Spanish legal and institutional framework on sustainability of wild truffle use are reviewed. In the current scenario, the decline of wild harvest is likely to continue and eventually make commercial harvesting economically unattractive, thus aggravating sustainability issues. Strengthening of property rights, rationalization of harvesting pressure, forest planning and involvement of public stakeholders are proposed as corrective measures.

    Rodrigues, Thiago Oliveira [Fundacao de Tecnologia Florestal e Geoprocessamento (NUPA/FUNTEC), Brasilia, DF (Brazil). Nucleo de Projetos Ambientais


    Brazil is the world's greater producer of charcoal and most of this production takes care of to the siderurgical sector. Thus, one understands that the Brazilian steel is produced of sustainable form. However, such sustainability is not based only on a renewable energy source. The origin of the wood for the carbonization, if proceeding from planted forests or native bushes, is crucial factor in this analysis. Beyond the ambient dimension, the sustainability of the charcoal segment also is influenced by its social, economic and technological aspects. In this context, the present article searches, through the construction and the analysis of the diagnosis of the charcoal in Brazil, to evaluate the sustainability of the sector and to consider alternatives to reach it. The current model of production of charcoal in the country is unsustainable. The main adopted systems of carbonization in Brazil are low level technological with consequent decrease production. The activity is unhealthy, beyond having many cases of enslaved and infantile work. The coal of native forests is much cheaper and the fiscalization is poor, fact that discourages its production from planted forests. But if the vegetal coal will be understood as an energy solution for the siderurgical sector measures can be taken to search a model of sustainable production. (author)

  13. Implications Of Fuelwood Demandon Sustainable Forest Conservation Of The Sub-Sahara Africa

    Directory of Open Access Journals (Sweden)

    Sogbon Odunwole


    Full Text Available Forests contribute immensely to economic and social development through formal trade in timber environmental services non- timber forest products safety net spiritual and aesthetic value. Wood is a key source of energy that has been used for millennia for cooking boiling water lighting and heating. Today about 2.5billion people depend on biomass energy for cooking and heating with 87 of this energy being provided by wood. In sub-Saharan African more than 90 of the population relies on wood fire that is firewood and charcoal as their primary source of domestic energy. Over 80 of urban householders and small industries use charcoal and firewood as their source of energy. Despite their numerous importance Africas forest continue to decline rapidly due to increase in agricultural practices into forest lands population growth and urbanization increased poverty high dependence on natural resources for subsistence and income through forest. The study centred on the implications of fuel wood demand on forest conservation in sub-Sahara Africa - a regional focus on Akure metropolitan area Ondo State. The specific objectives of the paper were to identify firewood consumption pattern in Akure metropolitan area and factors responsible for increased fuelwood demand in the study area. The paper adopted direct observation oral interview and 0.05 of the study area as sample size for the study. The study observed lack of adequate alternative poor implementation and enforcement of government regulation on forestry poverty and poor awareness on the menace of forest depletion among others. The paper posited provision of alternative fuel with subsidy regular awareness campaign proper monitoring implementation and enforcement of forest regulations with a view to achieving sustainable conservation.

  15. Sustainable Forest Bioenergy Development Strategies in Indochina: Collaborative Effort to Establish Regional Policies

    Directory of Open Access Journals (Sweden)

    Viktor J. Bruckman


    Full Text Available We conducted a feasibility study in Indochina (Cambodia, Laos, Myanmar, Thailand, and Vietnam with the aim of promoting biomass and bioenergy markets, technology transfer, rural development, and income generation. Policy development is guided by the International Union of Forest Research Institutions (IUFRO Task Force “Sustainable Forest Bioenergy Network”. In this paper, we highlight the achievements up to now and present results of a multi-stakeholder questionnaire in combination with a quantitative analysis of the National Bioenergy Development Plans (NBDPs. We found a gap between official documents and working group assessments. NBDPs are focused on the market development, technology transfer, and funding possibilities of a regional bioenergy strategy, while the respondents of a questionnaire (working groups favored more altruistic goals, i.e., sustainable resource management, environmental protection and climate change mitigation, generation of rural income, and community involvement, etc. We therefore suggest the following measures to ensure regulations that support the original aims of the network (climate change mitigation, poverty alleviation, sustainable resource use, and diversification of energy generation: (i Consideration of science-based evidence for drafting bioenergy policies, particularly in the field of biomass production and harvesting; (ii invitation of stakeholders representing rural communities to participate in this process; (iii development of sustainability criteria; (iv feedback cycles ensuring more intensive discussion of policy drafts; (v association of an international board of experts to provide scientifically sound feedback and input; and (vi establishment of a local demonstration region, containing various steps in the biomass/bioenergy supply chain including transboundary collaboration in the ACMECS region.

  19. Consequences of More Intensive Forestry for the Sustainable Management of Forest Soils and Waters

    Directory of Open Access Journals (Sweden)

    Eva Ring


    Full Text Available Additions of nutrients, faster growing tree varieties, more intense harvest practices, and a changing climate all have the potential to increase forest production in Sweden, thereby mitigating climate change through carbon sequestration and fossil fuel substitution. However, the effects of management strategies for increased biomass production on soil resources and water quality at landscape scales are inadequately understood. Key knowledge gaps also remain regarding the sustainability of shorter rotation periods and more intensive biomass harvests. This includes effects of fertilization on the long-term weathering and supply of base cations and the consequences of changing mineral availability for future forest production. Furthermore, because soils and surface waters are closely connected, management efforts in the terrestrial landscape will potentially have consequences for water quality and the ecology of streams, rivers, and lakes. Here, we review and discuss some of the most pertinent questions related to how increased forest biomass production in Sweden could affect soils and surface waters, and how contemporary forestry goals can be met while minimizing the loss of other ecosystem services. We suggest that the development of management plans to promote the sustainable use of soil resources and water quality, while maximizing biomass production, will require a holistic ecosystem approach that is placed within a broader landscape perspective.

  2. Comparing the sustainability of different action policy possibilities: application to the issue of both household survival and forest preservation in the corridor of Fianarantsoa. (United States)

    Bernard, C; Martin, S


    A sustainability issue for the rain forest in the corridor of Fianarantsoa (Madagascar) is to preserve the forest while ensuring the development of the local population. The aim of this paper is to determine whether the current situation is sustainable or not according to different action policy possibilities. We propose a general procedure based on viability analysis: Translation of sustainability issues into constraints on the system state; elaboration of a mathematical model of system evolution rules in the form of controlled dynamical system; computations of the viability kernels according to different action policy possibilities. Among control variables, we focus on monetary transfer. Without monetary transfer, we show that the current situation of the rain forest corridor is not sustainable in our mathematical modeling framework. We then estimate the minimal maximal amount per year necessary to make the current situation sustainable. Copyright © 2013 Elsevier Inc. All rights reserved.

  4. The role of knowledge management tools in supporting sustainable forest management

    Energy Technology Data Exchange (ETDEWEB)

    Vacik, H.; Torresan, C.; Hujala, T.; Khadka, C.; Reynolds, K.


    Aim of study: Knowledge Management (KM) tools facilitate the implementation of knowledge processes by identifying, creating, structuring, and sharing knowledge through use of information technology in order to improve decision-making. In this contribution, we review the way in which KM tools and techniques are used in forest management, and categorize a selected set of them according to their contribution to support decision makers in the phases of problem identification, problem modelling, and problem solving. Material and methods: Existing examples of cognitive mapping tools, web portals, work flow systems, best practices, and expert systems as well as intelligent agents are screened for their applicability and use in the context of decision support for sustainable forest management. Evidence from scientific literature and case studies is utilized to evaluate the contribution of the different KM tools to support problem identification, problem modelling, and problem solving. Main results: Intelligent agents, expert systems and cognitive maps support all phases of the forest planning process strongly. Web based tools have good potential to support participatory forest planning. Based on the needs of forest management decision support and the thus-far under utilized capabilities of KM tools it becomes evident that future decision analysis will have to consider the use of KM more intensively. Research highlights: As the problem-solving process is the vehicle for connecting both knowledge and decision making performance, the next generation of DSS will need to better encapsulate practices that enhance and promote knowledge management. Web based tools will substitute desktop applications by utilizing various model libraries on the internet. (Author)

    Howard, Keith A.; Nielson, Jane E.; Simpson, Robert W.; Hazlett, Richard W.; Alminas, Henry V.; Nakata, John K.; McDonnell, John R.


    At the request of the U.S. Bureau of Land Management, approximately 105,200 acres of the Turtle Mountains Wilderness Study Area (CDCA-307) were evaluated for mineral resources (known) and resource potential (undiscovered). In this report, the area studied is referred to as "the wilderness study area" or simply "the study area"; any reference to the Turtle Mountain Wilderness Study Area refers only to that part of the wilderness study area for which a mineral survey was requested by the U.S. Bureau of Land Management.The wilderness study area is in southeastern San Bernardino County, Calif. Gold, silver, copper, and lead have been mined within and adjacent to the study area. Copper-zinc-silver-gold mineral occurrences are found in the southern part and gold-silver mineral occurrences are found in the northern part of the study area; identified low- to moderate-grade gold-silver resources occur adjacent to the study area along the western boundary. Six areas in the south-central and northwestern parts of the study area have high resource potential, two broad areas have moderate resource potential, and part of the southwest corner has low resource potential for lode gold, silver, and associated copper, lead, zinc, molybdenum, and tungsten. Alluvium locally within one of these areas has moderate resource potential for placer gold and silver, and the entire area has low resource potential for placer gold and silver. There is low resource potential for perlite, ornamental stone (onyx marble and opal), manganese, uranium and thorium, pegmatite minerals, and oil and gas within the study area. Sand and gravel are abundant but are readily available outside the wilderness study area.

  7. Towards an ecologically sustainable energy production based on forest biomass - Forest fertilisation with nutrient rich organic waste matter

    Energy Technology Data Exchange (ETDEWEB)

    Roegaard, Pia-Maria; Aakerback, Nina; Sahlen, Kenneth; Sundell, Markus [Swedish Polytechnic, Vasa (Finland)


    The project is a collaboration between Swedish Univ. of Agricultural Sciences, Faculty of Forest Sciences in Umeaa, Swedish Polytechnic, Finland in Vaasa and the Finnish Forest Research Institute in Kannus. Today there are pronounced goals within the EU that lead towards an ecologically sustainable community and there is also a global goal to decrease net carbon dioxide emissions. These goals involve among other things efforts to increase the use of renewable biofuel as energy source. This will result in an enlarged demand for biomass for energy production. Therefore, the forest resources in the Nordic countries will be required for energy production to a far greater extent in the future. One way to meet this increased tree biomass demand is to increase forest tree growth through supply of nutrients, of which nitrogen is the most important. Organic nutrient rich waste matter from the society, such as sewage sludge and mink and fox manure compost from fur farms might be used as forest fertilizer. This would result in increased supply of renewable tree biomass, decreased net carbon dioxide emissions, increased forest ecosystem carbon sequestration, decreased methane emissions from sewage sludge landfill and decreased society costs for sludge landfill or incineration. Therefore, the purpose of this project is to develop methods for forest fertilisation with nutrient rich organic waste matter from municipal wastewater, sludge and manure from mink and fox farms. The project may be divided into three main parts. The first part is the chemical composition of the fertiliser with the objective to increase the nitrogen content in sludge-based fertilisers and in compost of mink and fox manure. The second part involves the technique and logistics for forest fertilisation i.e., to develop application equipment that may be integrated in existing forest technical systems. The third part consists of field fertilisation investigations and an environmental impact assessment

    The Pedra Wilderness Study Area, located approximately 30 mi northeast of Durango, Colorado, was evaluated for its mineral-resource potential. Geochemical and geophysical studies indicate little promise for the occurrence of mineral or energy resources in this area. This conclusion is supported by the findings of the earlier study and is suggested by the absence of significant mining activity in the area.

    Full Text Available Background and Purpose: During the Erasmus+ project “Cooperation for Innovative Approach in Sustainable Forest Management Training (CIA2SFM” a study of the existing vocational education and training (VET and lifelong learning (LLL programmes in the field of sustainable forest management (SFM was conducted in Austria, Croatia and Slovenia. The aim of this paper is to get an overview of and analyse SFM-related VET and LLL programmes in the study area, with an emphasis on the identification of good practice examples and providing recommendations for improvement. Materials and Methods: A combined approach of literature review, Internet search and consultations with training providers was applied in order to collect data on training programmes conducted in the period 2006-2015 in Austria, Croatia and Slovenia. The programmes were analysed based on topics, types of methods used, existence of specified learning outcomes, programme evaluation by participants and how the programme was advertised. The analysis employed basic descriptive statistics. Topics were grouped into broader themes. Only training programmes targeting private forest owners, forestry professionals, and forestry entrepreneurs were analysed. Three examples of good practice in each country were selected based on collaboratively developed criteria. Results: In Austria, Croatia and Slovenia numerous training courses related to SFM were conducted in the analysed period, predominantly addressing target groups in forestry sector and covering a variety of topics. The relative importance of themes varied among countries. In order to facilitate the knowledge uptake by participants various methods were applied. Although indoor ex-cathedra approaches prevailed, it could be recognized that there is a growth in interest for foster demonstrations in the field, organizing field trips, emphasize on practical work and combining methods and approaches in most countries. Conclusions: Even if national

  13. Conservation planning for biodiversity and wilderness: a real-world example. (United States)

    Ceauşu, Silvia; Gomes, Inês; Pereira, Henrique Miguel


    Several of the most important conservation prioritization approaches select markedly different areas at global and regional scales. They are designed to maximize a certain biodiversity dimension such as coverage of species in the case of hotspots and complementarity, or composite properties of ecosystems in the case of wilderness. Most comparisons between approaches have ignored the multidimensionality of biodiversity. We analyze here the results of two species-based methodologies-hotspots and complementarity-and an ecosystem-based methodology-wilderness-at local scale. As zoning of protected areas can increase the effectiveness of conservation, we use the data employed for the management plan of the Peneda-Gerês National Park in Portugal. We compare the approaches against four criteria: species representativeness, wilderness coverage, coverage of important areas for megafauna, and for regulating ecosystem services. Our results suggest that species- and ecosystem-based approaches select significantly different areas at local scale. Our results also show that no approach covers well all biodiversity dimensions. Species-based approaches cover species distribution better, while the ecosystem-based approach favors wilderness, areas important for megafauna, and for ecosystem services. Management actions addressing different dimensions of biodiversity have a potential for contradictory effects, social conflict, and ecosystem services trade-offs, especially in the context of current European biodiversity policies. However, biodiversity is multidimensional, and management and zoning at local level should reflect this aspect. The consideration of both species- and ecosystem-based approaches at local scale is necessary to achieve a wider range of conservation goals.

  17. REDDuced: From sustainability to legality to units of carbon—The search for common interests in international forest governance

    International Nuclear Information System (INIS)

    McDermott, Constance L.


    Highlights: ► Global forest governance has narrowed in focus from sustainability to carbon. ► Translating forests into carbon units creates an appearance of global transparency. ► Controversial environmental and social concerns have been reframed as “safeguards”. ► Resulting in a proliferation of safeguarding initiatives and new complexities. ► Hence flows of information increase but fail to facilitate global coordination. -- Abstract: This paper examines the institutional history of international forest governance, from the emergence of global intergovernmental forestry forums, to non-state market-based certification schemes, to regional illegal logging initiatives, to Reducing Emissions from Deforestation and Degradation and forest enhancement (REDD+) under the UNFCCC. It observes how the early initiatives were criticised for their failure to achieve coordinated and widespread action on forest conservation due to a lack of economic incentives and conflict over environmental and social priorities. This failure has been proceeded by a narrowing of core focus across each successive institution—from sustainability to legality to units of carbon—thereby transforming forest conservation into an increasingly legible and tradable commodity. Indeed, a wide range of environmental, economic and social actors appear to share the goal of making forest management more globally legible. This narrowing of focus, however, has served to displace rather than resolve a large array of environmental and social conflicts. The issues have been displaced across both space and time, generating a growing plethora of institutions involved in defining REDD+ modalities and “safeguards”, including various UN bodies and programmes, international development banks, private certification schemes and national and subnational governments. Meanwhile there is little evidence of whether, where and how these efforts might affect forest change. In fact, the largest impact of REDD

  20. The role of knowledge management tools in supporting sustainable forest management

    Directory of Open Access Journals (Sweden)

    H. Vacik


    Full Text Available Aim of study: Knowledge Management (KM tools facilitate the implementation of knowledge processes by identifying, creating, structuring, and sharing knowledge through use of information technology in order to improve decision-making. In this contribution, we review the way in which KM tools and techniques are used in forest management, and categorize a selected set of them according to their contribution to support decision makers in the phases of problem identification, problem modelling, and problem solving.Material and Methods: Existing examples of cognitive mapping tools, web portals, workflow systems, best practices, and expert systems as well as intelligent agents are screened for their applicability and use in the context of decision support for sustainable forest management. Evidence from scientific literature and case studies is utilized to evaluate the contribution of the different KM tools to support problem identification, problem modelling, and problem solving.Main results: Intelligent agents, expert systems and cognitive maps support all phases of the forest planning process strongly. Web based tools have good potential to support participatory forest planning. Based on the needs of forest management decision support and the thus-far underutilized capabilities of KM tools it becomes evident that future decision analysis will have to consider the use of KM more intensively. Research highlights: As the problem-solving process is the vehicle for connecting both knowledge and decision making performance, the next generation of DSS will need to better encapsulate practices that enhance and promote knowledge management. Web based tools will substitute desktop applications by utilizing various model libraries on the internet.Keywords: best practices; cognitive mapping; expert systems; intelligent agents; web portals; workflow systems; Decision Support Systems. 

  1. Mineral resources of the Swasey Mountain and Howell Peak Wilderness Study Areas, Millard County, Utah

    Energy Technology Data Exchange (ETDEWEB)

    Lindsey, D.A.; Zimbelman, D.R.; Campbell, D.L.; Duval, J.S.; Cook, K.L.; Podwysocki, M.H.; Brickey, D.W.; Yambrick, R.A.; Tuftin, S.E.


    The Swasey Mountain and the Howell Peak Wilderness Study Areas are underlain by an east-dipping sequence of carbonate rocks, shale, and quartzite of Cambrian age. The Sand Pass mineralized area, immediately northwest of the Swasey Mountain Wilderness Study Area, contains numerous occurrences of jasperoid, small igneous intrusions of Tertiary age, and geochemical anomalies; the mineralized area has been explored for gold. Although no identified resources of metals are known in or near the wilderness study areas, the distribution of geologic structures and stream-sediment geochemical anomalies indicates there is a moderate potential for undiscovered resources of lead, zinc, copper, molybdenum, silver, and gold. An area of moderate potential for undiscovered resources of these metals extends south and east into the Swasey Mountain Wilderness Study Area from the Sand Pass mineralized area. A second area of moderate potential for undiscovered resources of these metals extends from the southern part of the Swasey Mountain Wilderness Study Area across the western part of the Howell Peak Wilderness Study Area. Both study areas contain inferred subeconomic resources of quartzite, high-purity limestone, and sand and gravel. Both areas have moderate resource potential for high-purity limestone and dolomite. Fossils, especially trilobites, of interest to collectors are present in both areas. The potential for undiscovered resources is moderate for oil and gas and is low for geothermal energy within the study areas. There is no potential for undiscovered resources of coal.

  3. Sustainability Impact Assessment of two forest-based bioenergy production systems related to mitigation and adaption to Climate Change (United States)

    Gartzia-Bengoetxea, Nahia; Arias-González, Ander; Tuomasjukka, Diana


    New forest management strategies are necessary to resist and adapt to Climate Change (CC) and to maintain ecosystem functions such as forest productivity, water storage and biomass production. The increased use of forest-based biomass for energy generation as well as the application of combustion or pyrolysis co-products such as ash or biochar back into forest soils is being suggested as a CC mitigation and adaptation strategy while trying to fulfil the targets of both: (i) Europe 2020 growth strategy in relation to CC and energy sustainability and (ii) EU Action Plan for the Circular Economy. The energy stored in harvested biomass can be released through combustion and used for energy generation to enable national energy security (reduced oil dependence) and the substitution of fossil fuel by renewable biomass can decrease the emission of greenhouse gases.In the end, the wood-ash produced in the process can return to the forest soil to replace the nutrients exported by harvesting. Another way to use biomass in this green circular framework is to pyrolyse it. Pyrolysis of the biomass produce a carbon-rich product (biochar) that can increase carbon sequestration in the soils and liquid and gas co-products of biomass pyrolysis can be used for energy generation or other fuel use thereby offsetting fossil fuel consumption and so avoiding greenhouse gas emissions. Both biomass based energy systems differ in the amount of energy produced, in the co-product (biochar or wood ash) returned to the field, and in societal impacts they have. The Tool for Sustainability Impact Assessment (ToSIA) was used for modelling both energy production systems. ToSIA integrates several different methods, and allows a quantification and objective comparison of economic, environmental and social impacts in a sustainability impact assessment for different decision alternatives/scenarios. We will interpret the results in order to support the bioenergy planning in temperate forests under the

  5. The ′Adat′ institution and the Management of Grand Forest ′Herman Yohannes′ in Indonesian Timor: The Role of Design Principles for Sustainable Management of Common Pool Resources

    Directory of Open Access Journals (Sweden)

    Jacko A van Ast


    Full Text Available Local success stories of sustainable forest management can inspire scientists and decision-makers. This article analyses the traditional ′Adat′ institution that plays a role in the management of Grand Forest Park ′Herman Yohannes′, in the Western part of Timor where the Adat forest management regulation has been formally restored. The original set of design principles for sustainable management of common pool resources of Elinor Ostrom (1990 has been used in this study as an analytical framework for understanding the role of the Adat institution in respect to the forest. In the park, the local community applies Adat for protection and management of the forest that has been its home for centuries. It appears that Ostrom′s design principles can be identified in the current Adat institution and play a role in the sustainable management of the forest. Although many other variables can lead to success or failure of institutions, the original (internal design principles are still valuable as a practical tool for building institutions that are - under certain conditions - able to sustain common pool resources. The findings confirm the importance of traditional institutions in successful forest management. The study recommends that decision-makers take into account existing traditional management systems that have shown long term functionality.

  7. A Sustainable Tourism Paradigm: Opportunities and Limits for Forest Landscape Planning

    Directory of Open Access Journals (Sweden)

    Dina Rizio


    Full Text Available The promotion of sustainable tourism models has been widely debated; many pages have been devoted to the attempt to provide the subject with a strong theoretical base and coherent structure. This said, it is still the case that, although such frameworks are crucial for the development of appropriate planning and policy instruments, their actual implementation continue to be fraught with difficulties. These problems are exacerbated when sustainable tourism entails development opportunities which require the support of the local community and the management of natural resources which are typically common goods. Under these circumstances, new management structures, which can both satisfy the needs of the local community and ensure the appropriate stewardship of the natural resources, must be created. Management solutions are not always easy to define and often need to be considered within a general framework, based on which individual cases are then formulated. This study analyses the connections between models of sustainable tourism and natural resource management considering the forest landscape case. This relationship is first examined from a theoretical perspective and then within a case study, in order to highlight the dual approach—both general and within a specific context.

    Full Text Available International market requires producers to proof the legality of their wood products to address the issues of illegal logging and illegal trade. Timber Legality Verification System (TLVS has been prepared by the Government of Indonesia that covering the upstream and downstream wood industries. This paper aims to evaluate gaps in the implementation of TLVS policy and its impact on the sustainability of timber industry. This study was using gap, descriptive and costs-structure analyzes. The study was conducted in three provinces, namely: DKI Jakarta, West Java and D.I. Yogyakarta. Research found that the effectiveness of the TLVS implementation was low due to relatively rapid policy changes. This situation became disincetive for investments in timber business. Private sector perceived that TLVS policy should be applied in the upstream of timber business. Hence, the industry and market in the downstream have not been fully support to this system. Furthermore, TLVS policy implementation was considered ineffective by timber industry as well as private forest managers, especially by micro industry and smallholder private forests. This situation threatened the sustainability of timber industry and private forests. Therefore, Institutions should be strengthened in order to improve the quality of human resources and the competitiveness of products.

  18. Research Priorities for the Conservation and Sustainable Governance of Andean Forest Landscapes

    Directory of Open Access Journals (Sweden)

    Sarah-Lan Mathez-Stiefel


    Full Text Available The long-term survival of Andean forest landscapes (AFL and of their capacity to contribute to sustainable development in a context of global change requires integrated adaptation and mitigation responses informed by a thorough understanding of the dynamic and complex interactions between their ecological and social components. This article proposes a research agenda that can help guide AFL research efforts for the next 15 years. The agenda was developed between July 2015 and June 2016 through a series of workshops in Ecuador, Peru, and Switzerland and involved 48 researchers and development experts working on AFL from different disciplinary perspectives. Based on our review of current research and identification of pressing challenges for the conservation and sustainable governance of AFL, we propose a conceptual framework that draws on sustainability sciences and social–ecological systems research, and we identify a set of high-priority research goals and objectives organized into 3 broad categories: systems knowledge, target knowledge, and transformation knowledge. This paper is intended to be a reference for a broad array of actors engaged in policy, research, and implementation in the Andean region. We hope it will trigger collaborative research initiatives for the continued conservation and sustainable governance of AFL.

  1. Counseling for the Wilderness Athlete and Adventurer During a Preparticipation Evaluation for Preparation, Safety, and Injury Prevention. (United States)

    Young, Justin Mark J; Campbell, Aaron D; Raastad, Kate K


    Wilderness sports and adventures continue to increase in popularity. Counseling is an essential element of the preparticipation evaluation (PPE) for athletes in traditional sports. This approach can be applied to and augmented for the wilderness athlete and adventurer. The authors reviewed the literature on counseling during PPEs and gathered expert opinion from medical professionals who perform such PPEs for wilderness sports enthusiasts. The objective was to present findings of this review and make recommendations on the counseling component of a wilderness sports/adventure PPE. The counseling component of a PPE for wilderness sports/adventures should take place after a basic medical evaluation, and include a discussion on sport or activity-specific injury prevention, personal health, travel recommendations, and emergency event planning. Counseling should be individualized and thorough, and involve shared decision making. This should take place early enough to allow ample time for the athlete or adventurer to further prepare as needed based on the recommendations. Resources may be recommended for individuals desiring more information on selected topics. Copyright © 2015. Published by Elsevier Inc.

  2. Holocene variations of wildfire occurrence as a guide for sustainable management of the northeastern Canadian boreal forest

    Directory of Open Access Journals (Sweden)

    Ahmed El-Guellab


    Full Text Available Background Cumulative impacts of wildfires and forest harvesting can cause shifts from closed-crown forest to open woodland in boreal ecosystems. To lower the probability of occurrence of such catastrophic regime shifts, forest logging must decrease when fire frequency increases, so that the combined disturbance rate does not exceed the Holocene maximum. Knowing how climate warming will affect fire regimes is thus crucial to sustainably manage the forest. This study aimed to provide a guide to determine sustainable forest harvesting levels, by reconstructing the Holocene fire history at the northern limit of commercial forestry in Quebec using charcoal particles preserved in lake sediments. Methods Sediment cores were sampled from four lakes located close to the northern limit of commercial forestry in Quebec. The cores were sliced into consecutive 0.5 cm thick subsamples from which 1 cm3 was extracted to count and measure charcoal particles larger than 150 microns. Age-depth models were obtained for each core based on accelerator mass spectroscopy (AMS radiocarbon dates. Holocene fire histories were reconstructed by combining charcoal counts and age-depth models to obtain charcoal accumulation rates and, after statistical treatment, long-term trends in fire occurrence (expressed as number of fires per 1000 years. Results Fire occurrence varied between the four studied sites, but fires generally occurred more often during warm and dry periods of the Holocene, especially during the Holocene Thermal Maximum (7000–3500 cal. BP, when fire occurrence was twice as high as at present. Conclusions The current fire regime in the study area is still within the natural range of variability observed over the Holocene. However, climatic conditions comparable to the Holocene Thermal Maximum could be reached within the next few decades, thus substantially reducing the amount of wood available to the forest industry.

  3. Towards the sustainable management of thuya (Tetraclinis articulata (Vahl.) Mast.) forests in Tunisia: models for main tree attributes

    Energy Technology Data Exchange (ETDEWEB)

    Calama, R.; Sanchez-Gonzalez, M.; Garchi, S.; Ammari, Y.; Canellas, I.; Tahar, S.


    The thuya (Tetraclinis articulata (Vahl.) Mast.) forests are one of the most important ecosystems in semiarid environments in north-western Africa, providing important economic profit and social services to local populations. However, lack of tools aiding sustainable management of these forests is detected. In the present work models for the main tree attributes as total height, crown diameter, height to crown base and stem form are developed for the species, using data from a net of plots installed in JbelLattrech region, in the NE Tunisia. Presented models allow characterizing the actual state and timber production of forests by using variables measured in typical forest inventories and conform a preliminary step for the future development of dynamic growth models.

  9. Harnessing indigenous knowledge for sustainable forest management in Ghana

    Directory of Open Access Journals (Sweden)

    Margaret Sraku-Lartey


    Full Text Available This paper makes a case for harnessing indigenous knowledge (IK for sustainable national development in Ghana. IK according to the World Bank is the basic component of any country’s knowledge system and it is upon this knowledge that scientific research builds. In Ghana the Government has recognized the need to harness IK for sustainable national development and has therefore incorporated it into the National Science, Technology and Innovation Development Programme. But there is no evidence however that scientific research in Ghana actually takes IK into consideration during the research process. This paper discusses the concept of indigenous knowledge, its relevance in scientific discourse and the need for harnessing it for national development in Ghana. A desk study was conducted using journal publications, research and technical reports, online databases and the internet. About sixty articles were analysed using the thematic synthesis method under the following broad headings: Importance of Indigenous knowledge, Indigenous forest foods, Indigenous medicines, IK and food security, the management and processing of IK and the protection of Indigenous Knowledge.The results of the study established the need to document the local knowledge using appropriate procedures and strategies. It also concludes by suggesting that IK in Ghana must be protected by law and integrated into formal science.

Its forestry production plays an important part in sustainable development of ecological environment and socio-economy in the areas. Based on the analysis of the characteristics of forest resources and the problems existing in the forest production, the basic pattern of sustainable management of forest resources are suggested as following: 1) the development of forest production should be promoted systematically under the guidance of sustainable development theory; 2) the legal system of forestry should be perfected, and the forest should be managed according to law; 3) coordinated by the government, the internal motive forces for sustainable development of forestry should be strengthened; 4) the project of "science and education promoting forestry" should be carried out; 5) the open policy should be further implemented, and the international cooperation on forestry be enhanced.%分析了海南岛森林资源的特点,指出林业生产存在的主要问题。根据其特点,构建森林资源可持续经营管理的基本模式,并对海南林业可持续发展提出相应的对策。

    Full Text Available The problems that hamper the financing of sustainable forest management (SFM are manifold and complex. However, forestry is also facing unprecedented opportunities. The multiple functions and values of forests are increasingly recognized as part of the solution to pressing global issues (e.g., climate change, energy scarcity, poverty, environmental degradation, biodiversity loss and raw material supply. Emerging initiatives to enhance forest carbon stocks and cut greenhouse gas emissions associated with forest clearing (known as REDD+, together with voluntary carbon markets, are offering additional funding options for SFM. Indigenous peoples, local communities and small scale farmers feature as key players in the discourse on implementing such initiatives. Based on the experience of countries developing national forest financing strategies and instruments, we suggest the following points be considered when financing such initiatives, particularly for small scale forestry: (1 Integrate financing of REDD+ and similar initiatives within broader national strategies for SFM financing; (2 Design REDD+ finance mechanisms that are ‘community ready’, i.e., tailored to local realities; (3 Consider existing livelihood strategies as the starting point; (4 Build on existing structures, but be mindful of their strengths and weaknesses; (5 Be strategic with your priority actions; and (6 Promote innovation, knowledge sharing and information exchange.

  17. International and Domestic Sustainable Forest Management Policies: Distributive Effects on Power among State Agencies in Bangladesh

    Directory of Open Access Journals (Sweden)

    Lukas Giessen


    Full Text Available The last two decades of forest policy discussions have been dominated by calls for sustainable management of forest resources. Consequently, multiple international and domestic policies, supporting sustainable forest management (SFM, have evolved in numerous jurisdictions. Policies in developing countries often rely on foreign donors’ projects, which supplement domestic SFM policy. These policies assign various policy tasks to specific public bureaucracies, who then compete for these very tasks, as well as the related staff and budgets. Therefore, project and policy task assignment greatly influences bureaucratic power. This article analyzes the distributive effects of SFM policy on power (in terms of coercion, incentives and dominant information among relevant domestic and foreign donor bureaucracies in Bangladesh. Concepts from power theory, bureaucratic politics theory, and concepts of policy and policy process were combined to analyze 121 Bangladeshi SFM policies from 1992–2013, which assign a total of 1012 policy tasks to specific public bureaucracies. Using qualitative content analysis, inferences about power were assigned to specific competing bureaucracies by the totality of SFM policies made. Results identify domestic and foreign bureaucracies whose power distribution benefit most from the SFM policies viz. their competitors. It is concluded that bureaucracies gaining the most power set the limits and directions in designing, implementing and evaluating various elements of any national SFM policies.

  1. Small Mushrooms for Big Business? Gaps in the Sustainable Management of Non-Timber Forest Products in Southwest China

    Directory of Open Access Journals (Sweden)

    Jun He


    Full Text Available The challenge of managing forests for the production of commercial non-timber forest products (NTFPs lies in promoting economic development by maintaining and even increasing production while simultaneously maintaining or improving ecological conditions. The discussion of forest management therefore encompasses a wide range of social, economic, political, and ecological questions. Empirically, it is clear that both market and government failure can lead to unsustainable management in commercial NTFP use. How can we manage the market and at the same time formulate good policies? Taking cases from Southwest China, this paper critically examines the current development of NTFP commercialization in the mountainous region of Southwest China. It focuses particularly on three pieces of research on mushroom collection and marketing. By examining empirical data, the paper analyzes current gaps in the policy and the market in mountainous areas in the context of promoting sustainable use of NTFP. It examines the market structure from the perspective of market failure and explores the government’s failure to promote commercial NTFPs. We recommend economic and political decentralization, capacity building, and government investment as means to improve sustainable management.

    The future economy will be more and more dependent on the sustainable use of natural resources, at least if the views on the importance and possibilities of the bioeconomy are realized in practice. The sustainability of the use of natural resources has previously been studied from the perspective of ecological sustainability in particular. Social sustainability has also been examined in several studies. On the other hand, economic sustainability is a prerequisite for developing business activities. As defining and framing of cultural sustainability is challenging, up to now it has only been discussed to some extent, although the importance of cultural sustainability has not been understated. When developing the sustainability of the use of natural resources, all the above-mentioned dimensions of sustainability are present in parallel and they need to be acknowledged in decision-making. The starting point of this study is that natural resources need to be used sustainably and that different options for utilizing natural resources need to be compared from the sustainability perspective, without giving higher priority to any sustainability dimension compared to others beforehand. In this study four production chains based on energy use of forest biomass were examined: (1) local district heating based on forest chips, (2) combined heat and power with wood and peat, (3) wood pellet production from by-products of the wood product industry, and (4) biodiesel production based on wood and peat. The indicators for different sustainability dimensions in the studied production chains were determined through expert interviews and the indicator values were determined through literature review and interviews. The mathematical examination of sustainability was based on multi-criteria decision analysis (MCDA) so that a computational tool suitable for the calculations was developed. In total, 20 - 40 indicators were defined for each sustainability dimension; out of these, five to

  5. Mineral Resources of the Morey and Fandango Wilderness Study Areas, Nye County, Nevada (United States)

    John, David A.; Nash, J. Thomas; Plouff, Donald; McDonnell, John R.


    The Morey (NV-060-191) and Fandango (NV-060-190) Wilderness Study Areas are located in the northern Hot Creek Range about 25 mi north of Warm Springs, Nev. At the request of the Bureau of Land Management, 46,300 acres of the Morey and Fandango Wilderness Study Areas were studied. In this report, the area studied is referred to as 'the wilderness study area', or simply 'the study area'. Geologic, geochemical, geophysical, and mineral surveys were conducted by the USGS and the USBM in 1984 to appraise the identified mineral resources and to assess the mineral resource potential of the study areas. These studies indicate that there are small identified resources of zinc, lead, and silver at the Lead Pipe property in the Fandango Wilderness Study Area, several areas of high potential for the occurrence of gold resources in the Fandango study area, small areas of low and moderate potential for the occurrence of silver, lead, and zinc resources in the Fandango study area, areas of moderate and high potential for the occurrence of silver, lead, and zinc resources in the Morey study area, and an area of low potential for copper, molybdenum, and tin in the Morey study area. Both study areas have low resource potential for petroleum, natural gas, uranium, and geothermal energy.

  6. Sustainable development and energy supply

    International Nuclear Information System (INIS)

    Levi, H.W.


    'Sustainable' is an old established term which has made a political career in the past ten years. The roots of this career extend back into the 18th century, when an economic concept of forest management was developed to replace yield maximization achieved by means of complete deforestation by yield optimization attained by conservative forest management. This latter type of forest management was termed 'sustainable'. The language used in today's sustainability debate was based on the idea of preserving the capital provided by nature and living on the interest. As a consequence, the term 'sustainable' became one of the key points in environmental policy and economic policy after the Brundtland report had been published (V. Hauff, 1987), which also constitutes the background to this article. (orig.) [de

  7. A Fifty-Year Sustainability Assessment of Italian Agro-Forest Districts

    Directory of Open Access Journals (Sweden)

    Fabio Recanatesi


    Full Text Available As cropland management and land use shifted towards more intensive practices, global land degradation increased drastically. Understanding relationships between ecological and socioeconomic drivers of soil and landscape degradation within these landscapes in economically dynamic contexts such as the Mediterranean region, requires multi-target and multi-scalar approaches covering long-term periods. This study provides an original approach for identifying desertification risk drivers and sustainable land management strategies within Italian agro-forest districts. An Environmental Sensitivity Area (ESA approach, based on four thematic indicators (climate, soil, vegetation and land-use and a composite index of desertification risk (ESAI, was used to evaluate changes in soil vulnerability and landscape degradation between the years 1960 and 2010. A multivariate model was developed to identify the most relevant drivers causing changes in land susceptibility at the district scale. Larger districts, and those with a higher proportion of their total surface area classified as agro-forest, had a significantly lower increase in land susceptibility to degradation during the 50 years when compared with the remaining districts. We conclude that preserving economic viability and ecological connectivity of traditional, extensive agricultural systems is a key measure to mitigate the desertification risk in the Mediterranean region.

    Omar Espinoza; Urs Buehlmann; Michael Dockry


    Forest certification systems are voluntary, market-based initiatives to promote the sustainable use of forests. These standards assume that consumers prefer products made from materials grown in an environmentally sustainable fashion, and this in turn creates incentives for companies to adopt responsible environmental practices. One of the major reasons for the...

    Eriksson, Mats; Samuelson, Lotta; Jägrud, Linnéa; Mattsson, Eskil; Celander, Thorsten; Malmer, Anders; Bengtsson, Klas; Johansson, Olof; Schaaf, Nicolai; Svending, Ola; Tengberg, Anna


    A growing world population and rapid expansion of cities increase the pressure on basic resources such as water, food and energy. To safeguard the provision of these resources, restoration and sustainable management of landscapes is pivotal, including sustainable forest and water management. Sustainable forest management includes forest conservation, restoration, forestry and agroforestry practices. Interlinkages between forests and water are fundamental to moderate water budgets, stabilize runoff, reduce erosion and improve biodiversity and water quality. Sweden has gained substantial experience in sustainable forest management in the past century. Through significant restoration efforts, a largely depleted Swedish forest has transformed into a well-managed production forest within a century, leading to sustainable economic growth through the provision of forest products. More recently, ecosystem services are also included in management decisions. Such a transformation depends on broad stakeholder dialog, combined with an enabling institutional and policy environment. Based on seminars and workshops with a wide range of key stakeholders managing Sweden's forests and waters, this article draws lessons from the history of forest management in Sweden. These lessons are particularly relevant for countries in the Global South that currently experience similar challenges in forest and landscape management. The authors argue that an integrated landscape approach involving a broad array of sectors and stakeholders is needed to achieve sustainable forest and water management. Sustainable landscape management-integrating water, agriculture and forests-is imperative to achieving resilient socio-economic systems and landscapes.

  10. The sustainability of carbon sinks in forests. Studying the sensitivity of forest carbon sinks in the Netherlands, Europe and the Amazon to climate and management

    International Nuclear Information System (INIS)

    Kruijt, B.; Kramer, K.; Van den Wyngaert, I.; Groen, R.; Elbers, J.A.; Jans, W.W.P.


    The aim of this study was to assess the sustainability of carbon sinks in managed or unmanaged forests of Europe and the Amazon. First, the functioning and seasonal variability of the carbon sink strength in forest ecosystems was analysed in relation to climate variability. For this, existing global data sets of ecosystem fluxes measured by eddy correlation were analysed. A simple, comprehensive empirical model was derived to represent these flux variabilities. Also, new soil respiration measurements were initiated in the Netherlands and Amazonia and their usefulness to understand the uptake- and emission components of carbon exchange was analysed. Then, two long-term forest dynamics models were parameterised (FORSPACE and CENTURY) for Dutch Pinus and Fagus forests, to study the development of forest carbon stocks over a century under different management and climate scenarios. Finally, using the empirical model as well as the long-term models, scenario predictions were made. It turns out that uptake rates are expected to decrease in a climate with higher temperatures, but that storage capacity for carbon can be expected to be slightly enhanced, especially if also the management intensity is carefully tuned down

  13. Action plan to counteract soil acidification and to promote sustainable use of forest land

    International Nuclear Information System (INIS)


    This report consists of the National Board of Forestry's proposals on a plan to counteract soil acidification and to promote sustainable use of forest land. In 1989 the government requested the National Board of Forestry to start experimental activities to find measures to counteract soil acidification. In 1997 the Board presented a proposal for liming and vitalisation of forest land. An Environmental Impact Assessment of the proposal was submitted in 1999, after which a revision of the plan was started. In order to obtain better basic knowledge of the situation, the Board of Forestry commissioned nine reports that dealt with different aspects of soil acidification and corrective measures. Major emphasis has also been placed on the national environmental quality goals and the national plan for liming of lakes and waterways. The report is divided into three parts. The first part explains the Board of Forestry's proposals on measures to counteract soil acidification, and the second part, the description of the situation today, presents the conditions for the design of the plan such as political goals and guidelines that affect the plan and its design, the knowledge available today on soil acidification, its effects, possibilities for recovery, and possible measures that can be used. The third and final part contains brief summaries of the responses to the plan when circulated for comments. The action plan allows a return of the buffering capacity of the most acidified forest land, mainly in southern and southwestern Sweden. The Board of Forestry proposes that the spreading of ashes and lime is done within drainage areas where the natural recovery is assessed to be slow and insufficient, and where the leaching of toxic aluminium from forest land is hazardous to the aquatic ecosystem. In the assessments made by the Board, between 200,000 and 350,000 hectares of forest land may require measures of this kind. The Board of Forestry is of the opinion that a three

  1. Forgotten Forests? Food Potential of Ancient Coffee Forests and Agroforestry Systems in the Southwestern Ethiopian Mountains, Seen Through a Gender Lens

    Directory of Open Access Journals (Sweden)

    Sarah Marie Nischalke


    Full Text Available Forests play an important role in the provision of food and livelihoods across the globe. Thus, forest protection contributes to a diverse set of Sustainable Development Goals. The Yayu Coffee Forest Biosphere Reserve in the southwestern Ethiopian mountains (elevation 1100–2300 m above sea level hosts an ancient coffee forest with high biodiversity and a large nutritional potential. It is managed in zones, and smallholder farmers can still use forest resources in the buffer and transitional zones in a sustainable manner. The forest is rarely used as a food source, although a large majority of the population in this area suffers from micronutrient deficiencies. This article investigates whether sustainable use of forest resources can contribute to the achievement of different Sustainable Development Goals by looking, through a gender lens, at which forest ecosystem services the community uses; traditional coffee farmers' perceptions of wild edible plants, agricultural territories, and labor divisions; and the constraining factors for forest conservation and sustainable agroforestry on private forest plots. Data for this study were collected through ethnography, transect walks, a sex-disaggregated household survey (n = 334, 32 semistructured interviews, 40 focus groups, and 13 key stakeholder interviews. One reason for neglecting the forest as a food source is that forests are considered a male territory, while vegetable raising and nutrition are female responsibilities. In addition, the collection of wild foods is perceived as a last resort during a famine and as a practice of tribal groups. Because coffee production represents the traditional livelihood source, farmers accept the need to conserve the forest, which is necessary to achieve the Sustainable Development Goals. While it may have negative implications for food security, the absence of a tradition of collecting wild plants is positive news for forest conservation.

  2. Balancing shifting cultivation and forest conservation: lessons from a "sustainable landscape" in southeastern Mexico. (United States)

    Dalle, Sarah Paule; Pulido, María T; de Blois, Sylvie


    Shifting cultivation is often perceived to be a threat to forests, but it is also central to the culture and livelihoods of millions of people worldwide. Balancing agriculture and forest conservation requires knowledge of how agricultural land uses evolve in landscapes with forest conservation initiatives. Based on a case study from Quintana Roo, Mexico, and remote sensing data, we investigated land use and land cover change (LUCC) in relation to accessibility (from main settlement and road) in search of evidence for agricultural expansion and/or intensification after the initiation of a community forestry program in 1986. Intensification was through a shortening of the fallow period. Defining the sampling space as a function of human needs and accessibility to agricultural resources was critical to ensure a user-centered perspective of the landscape. The composition of the accessible landscape changed substantially between 1976 and 1997. Over the 21-year period studied, the local population saw the accessible landscape transformed from a heterogeneous array of different successional stages including mature forests to a landscape dominated by young fallows. We detected a dynamic characterized by intensification of shifting cultivation in the most accessible areas with milpas being felled more and more from young fallows in spite of a preference for felling secondary forests. We argue that the resulting landscape provides a poorer resource base for sustaining agricultural livelihoods and discuss ways in which agricultural change could be better addressed through participatory land use planning. Balancing agricultural production and forest conservation will become even more important in a context of intense negotiations for carbon credits, an emerging market that is likely to drive future land changes worldwide.

  5. Visualizing the Forest in a Boreal Forest Landscape—The Perspective of Swedish Municipal Comprehensive Planning

    Directory of Open Access Journals (Sweden)

    Camilla Thellbro


    Full Text Available At the international policy level, there is a clear link between access to information about forests and the work towards sustainable land use. However, involving forests in planning for sustainable development (SuD at the Swedish local level, by means of municipal comprehensive planning (MCP, is complicated by sector structure and legislation. Currently, there is a gap or hole in the MCP process when it comes to use and access to knowledge about forest conditions and forest land use. This hole limits the possibilities to formulate well-informed municipal visions and goals for sustainable forest land use as well as for overall SuD. Here we introduce an approach for compilation and presentation of geographic information to increase the preconditions for integrating forest information into Swedish MCP. We produce information about forest ownership patterns and forest conditions in terms of age and significant ecological and social values in forests for a case study municipality. We conclude that it is possible to effectively compile geographic and forest-related information to fill the hole in the municipal land use map. Through our approach, MCP could be strengthened as a tool for overall land use planning and hence as a base in SuD planning.

  6. Estimated impact of global population growth on future wilderness extent (United States)

    Dumont, E.


    Wilderness areas in the world are threatened by the environmental impacts of the growing global human population. This study estimates the impact of birth rate on the future surface area of biodiverse wilderness and on the proportion of this area without major extinctions. The following four drivers are considered: human population growth (1), agricultural efficiency (2), groundwater drawdown by irrigation (3), and non-agricultural space used by humans (buildings, gardens, roads, etc.) (4). This study indicates that the surface area of biodiverse unmanaged land will reduce with about 5.4% between 2012 and 2050. Further, it indicates that the biodiverse land without major extinctions will reduce with about 10.5%. These percentages are based on a commonly used population trajectory which assumes that birth rates across the globe will reduce in a similar way as has occurred in the past in many developed countries. Future birth rate is however very uncertain. Plausible future birth rates lower than the expected rates lead to much smaller reductions in surface area of biodiverse unmanaged land (0.7% as opposed to 5.4%), and a reduction in the biodiverse land without major extinctions of about 5.6% (as opposed to 10.5%). This indicates that birth rate is an important factor influencing the quality and quantity of wilderness remaining in the future.

  7. Options for REDD+ Voluntary Certification to Ensure Net GHG Benefits, Poverty Alleviation, Sustainable Management of Forests and Biodiversity Conservation

    Directory of Open Access Journals (Sweden)

    Michael Dutschke


    Full Text Available Our objective was to compare and evaluate the practical applicability to REDD+ of ten forest management, social, environmental and carbon standards that are currently active worldwide: Climate, Community and Biodiversity (CCB, CCB REDD+ Social and Environmental Standards (CCBA REDD+ S&E, CarbonFix Standard (CFS, Forest Stewardship Council (FSC, Global Conservation Standard (GCS, ISO 14064:2006, Plan Vivo Standard, Programme for Endorsement of Forest Certification (PEFC, SOCIALCARBON Standard and the Voluntary Carbon Standard (VCS. We developed a framework for evaluation of these standards relative to each other using four substantive criteria: (1 poverty alleviation, (2 sustainable management of forests (SMF, (3 biodiversity protection, (4 quantification and assessment of net greenhouse gas (GHG benefits; and two procedural criteria: (5 monitoring and reporting, and (6 certification procedures. REDD programs require assessment of GHG benefits, monitoring, reporting and certification. Our analysis shows that only the Voluntary Carbon Standard (VCS treats these three criteria comprehensively. No standard provides comprehensive coverage of the social and other environmental criteria. FSC, PEFC and CarbonFix provide comprehensive assessments of the sustainable forest management criterion. CCBA REDD+ S&E, CCB, and GCS provide comprehensive coverage of the biodiversity and poverty alleviation criteria. Experience in using these standards in pilot projects shows that projects are currently combining several standards as part of their strategy to improve their ability to attract investment, but costs of implementing several certification schemes is a concern. We conclude that voluntary certification provides useful practical experience that should feed into the design of the international REDD+ regime.

    Full Text Available ABSTRACTAs important as the establishment of projects of ecological restoration is its assessment post-implementation to know whether the area is becoming self-sustainable or need to be redirected. In this way, this study aimed to know the current situation of a 5-year-old rehabilitated riparian forest,inserted in an anthropogenic impacted region,at the das Velhas River, Minas Gerais State, studying the canopy openness and recruitment of seedlings as plant indicators. 15 plots were allocated in the forest, where hemispherical photographs were taken to analyze the canopy openness and evaluate all seedlings from 0.30 m to 1.30 m height.Canopy openness ranged from 23.7% to 38.8% between seasons and only 192 seedlings were found,from 13 species, five of them exotic and aggressive. Although canopy openness was low, it seems that lateral penetration of light has been favoring the development and dominancy of plants from invasive species, whereas few native ones have been recruited. The exotic/invasive plants may compromise the success of restoration mainly by competition with native planted species. The outcomes evidenced an unsustainability of the riparian forest and the requirement of some management actions to control exotic and invasive plants and ensure the preservation of the area and its ecological roles over time.

    Full Text Available In the fall of 1846, the first of 3,000 African American settlers set foot on their 40-acre plots in the Great Northern Wilderness of New York State, a place we now call the “forever wild” wilderness of the Adirondack State Park. These black settlers were the initial wave of a social experiment meant to destroy both slavery and, more generally, racism throughout the entire United States through the redemptive practice of a utopian agrarianism. The settlers understood that nature and culture, wilderness and society, were thickly, dialectically intertwined. And they weren’t alone: their efforts were seeded by the white abolitionist, Gerrit Smith; fertilized by the utopian socialist communes that covered the Northeast in the 1840s; and nurtured by abolitionists, both black and white. To United States environmental history, I add two threads less frequently seen: African American history and an intellectual history of radical politics. Following these threads has led me beyond the disciplinary confines of history and into larger debates about the cultural politics of wilderness. In this article I argue that the critical wilderness paradigm currently reigning both in and beyond historical scholarship has obscured nuanced, sometimes radical visions of the natural world. Instead of an ironic, deconstructed notion of a troubling wilderness, I suggest another heuristic, the ecology of freedom, which highlights past contingency and hope, and can furthermore help guide our present efforts, both scholastic and activist, to find an honorable, just way of living on the earth.

  15. Achieving sustainable ese of environment: a framework for payment for protected forest ecosystem service (United States)

    Widicahyono, A.; Awang, S. A.; Maryudi, A.; Setiawan, M. A.; Rusdimi, A. U.; Handoko, D.; Muhammad, R. A.


    Over the last decade, deforestation in Indonesia has reduced the forest area down to more than 6 million hectares. There is conflict that the protected forest ecosystem service is still often perceived as public goods. Many of them went unrecognized in planning process and continue to be undervalued. The challenge lies in maintaining socioeconomic development and ecosystem services sustainability without overlooking the people’s opportunities and improving their livelihoods over the long term. An integrated approach is required to understand the comprehensive concept of protected forest ecosystem service. This research aims to formulate a scheme of payment for ecosystem service (PES) in a protected forest. It is a first step towards the attempt for the value of ecosystem services to be reflected in decision-making. Literatures, previous researches and secondary data are reviewed thoroughly to analyze the interrelated components by looking at the environment as a whole and recognize their linkages that have consequences to one another both positive and negative. The framework of implementation of PES schemes outlines the complexity of human-environment interconnecting relationships. It evaluates the contributing actors of different interest i.e. long term use and short term use. The concept of PES accommodates the fulfillment of both conservation and exploitation with an incentive scheme to the contributing parties who are willing to implement conservation and issuance of compensation expense for any exploitation means. The most crucial part in this concept is to have a good and effective communication between every policy makers concerning the forest ecosystem and local communities.

    Nelson, Timothy R.; Miselis, Jennifer L.; Hapke, Cheryl J.; Brenner, Owen T.; Henderson, Rachel E.; Reynolds, Billy J.; Wilson, Kathleen E.


    Scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center in St. Petersburg, Florida, conducted a bathymetric survey of Fire Island from May 6-20, 2015. The USGS is involved in a post-Hurricane Sandy effort to map and monitor the morphologic evolution of the wilderness breach as a part of the Hurricane Sandy Supplemental Project GS2-2B. During this study, bathymetry data were collected with single-beam echo sounders and Global Positioning Systems, which were mounted to personal watercraft, along the Fire Island shoreface and within the wilderness breach. Additional bathymetry and elevation data were collected using backpack Global Positioning Systems on flood shoals and in shallow channels within the wilderness breach.

  1. Foreign capital, forest change and regulatory compliance in Congo Basin forests

    International Nuclear Information System (INIS)

    Brandt, Jodi S; Nolte, Christoph; Agrawal, Arun; Steinberg, Jessica


    Tropical forest change is driven by demand in distant markets. Equally, investments in tropical forest landscapes by capital originating from distant emerging economies are on the rise. Understanding how forest outcomes vary by investment source is therefore becoming increasingly important. We empirically evaluate the relationship between investment source and deforestation from 2000 to 2010 in the Republic of Congo. A Congolese forestry code was implemented in 2000 to mitigate degradation of production forests by standardizing all logging in the country according to sustainable forest management (SFM) guidelines. Following the implementation of this law, the majority (73%) of Congo’s production forests were managed by European (40%) and Asian (33%) companies. European concessions had the highest rates of total and core deforestation, followed by Asian concessions, indicating that the fragmentation of intact forests in Congo is strongly associated with industrial logging fueled by foreign capital. European concession holders were also far more likely to comply with SFM policies, followed by Asian concessions, suggesting that compliance with Sustainable Forest Management policies may not mitigate degradation in tropical production forests. Further evaluation of the relationship between investment source, regulatory compliance, and outcomes in tropical countries is essential for effective conservation of tropical forest ecosystems.

  4. Is Matang Mangrove Forest in Malaysia Sustainably Rejuvenating after More than a Century of Conservation and Harvesting Management? (United States)

    Van der Stocken, Tom; Quispe Zuniga, Melissa; Mohd-Lokman, Husain; Sulong, Ibrahim


    Matang Mangrove Forest Reserve (MMFR) in Peninsular Malaysia is under systematic management since 1902 and still considered as the best managed mangrove forest in the world. The present study on silvimetrics assessed the ongoing MMFR forest management, which includes a first thinning after 15 years, a second thinning after 20 years and clear-felling of 30-year old forest blocks, for its efficiency and productivity in comparison to natural mangroves. The estimated tree structural parameters (e.g. density, frequency) from three different-aged mangrove blocks of fifteen (MF15), twenty (MF20), and thirty (MF30) years old indicated that Bruguiera and Excoecaria spp. did not constitute a significant proportion of the vegetation (mangrove management based on a 30-year rotation is appropriate for the MMFR. Since Matang is the only iconic site that practicing sustainable wood production, it could be an exemplary to other mangrove locations for their improved management. PMID:25144689

  5. Contribution of Remote Sensing and GIS for Sustainable Forest Management in Côte d'Ivoire; Case of the classified Forest of TENE in the department of OUME (Côte d'Ivoire). (United States)

    Yao, N. A.


    The classified forest of TENE located in the department of OUME has a role of timber production characterized by a high logging. This operation requires a measure of preservation of sensitive sites to exploitation in order to maintain ecological functions, ecosystem and biodiversity living there. The parameters such as streams, slopes, wetlands and rivers are indicators of the existence of sensitive sites to preserve. However, no knowledge of the location, boundaries and the surface of these natural habitats makes its protection difficult. Thus, knowledge of the natural and conceptual environment at the forest of TENE is necessary for the preservation of the ecosystem and biodiversity, prerequisite for its sustainability. Furthermore, Remote Sensing and GIS are less expensive techniques for synthetic and fast analysis of these parameters at different scales as well as spatially and temporally. It should be noted that this study is focused on wetlands mapping in the forest of TENE for a sustainable management. The satellite image of December 2014 from Landsat 8 carried on the Operational Land Imager (OLI) sensor was used for analysis. The methodological approach is based primarily on prior knowledge of the spectral signatures of different elements on the image in different wavelengths. Then the thematic layers extraction of hydromorphic soil without and with vegetation are made by thresholding associated luminance values. The combination of the obtained layers allowed to map all wetlands in the forest of TENE. Finally, the superimposition of this layer with the water system was used to assess the conformity of the result with the reality on the ground. The result showed that the wetlands subject of sensitive sites are mainly found in the western part of the forest of TENE. They are also encountered along the rivers. These wetlands extend over a total area of 12,915 ha against 16,898.22 ha for the non wetlands with a coverage rate of 43.32 %. These areas should be

  6. Latent resilience in ponderosa pine forest: effects of resumed frequent fire. (United States)

    Larson, Andrew J; Belote, R Travis; Cansler, C Alina; Parks, Sean A; Dietz, Matthew S


    Ecological systems often exhibit resilient states that are maintained through negative feedbacks. In ponderosa pine forests, fire historically represented the negative feedback mechanism that maintained ecosystem resilience; fire exclusion reduced that resilience, predisposing the transition to an alternative ecosystem state upon reintroduction of fire. We evaluated the effects of reintroduced frequent wildfire in unlogged, fire-excluded, ponderosa pine forest in the Bob Marshall Wilderness, Montana, USA. Initial reintroduction of fire in 2003 reduced tree density and consumed surface fuels, but also stimulated establishment of a dense cohort of lodgepole pine, maintaining a trajectory toward an alternative state. Resumption of a frequent fire regime by a second fire in 2011 restored a low-density forest dominated by large-diameter ponderosa pine by eliminating many regenerating lodgepole pines and by continuing to remove surface fuels and small-diameter lodgepole pine and Douglas-fir that established during the fire suppression era. Our data demonstrate that some unlogged, fire-excluded, ponderosa pine forests possess latent resilience to reintroduced fire. A passive model of simply allowing lightning-ignited fires to burn appears to be a viable approach to restoration of such forests.

  7. Precision of Nest Method in Estimating Orangutan Population and Determination of Important Ecological Factors for Management of Conservation Forest

    Directory of Open Access Journals (Sweden)

    Yanto Santosa


    Full Text Available Orangutan as an umbrella species is closely interlinked with sustainable forest management meaning that the protection of this species has implications on the protection of other species and maintain ecosystem stability.  The total natural habitat required to support orangutan’s population could only be determined by the appropriate population size. It is associated with the carrying capacity to accommodate or fulfill the habitat requirements of a wildlife population. Selection and delineation of core and wilderness zones as habitat preference should be based on the results of preference test shown by the spatial distribution of orangutan population. Value of the coefficient  of  variation (CV was used to observe the precision of the population estimation and to identify important ecological factors in selection of nesting trees.  The study resulted in varied CV spatial values for various habitat types: 22.60%,  11.20%, and 13.30% for heath, lowland dipterocarp, and peat swamp forest, respectively. In the other side, CV temporal values for various habitat types were 5.35%, 22.60%, and 17.60% for heath, lowland dipterocarp, and peat swamp forest, respectively. This indicated that the population density in each type of forest ecosystems had a variation based on location and did not varied according to time of survey.  The use of  nest survey technique showed good reliable results in estimating orangutan population density.  Efforts to improve the precision of estimation can be done by formulating r value as the harmonic average of nest production rates and t as the average of nest decay time per nest category. Selection of habitat preference and nest trees were influenced by food availability thus should form important consideration in conducting nest survey to avoid bias in estimating orangutan populations.Keywords: conservation forest management, nest survey, orangutan, population size, ecological factors

  8. Sustaining Biodiversity in the Oregon Coast Range: Potential effects of Forest Policies in a Multi-ownership Province

    Directory of Open Access Journals (Sweden)

    Brenda C. McComb


    Full Text Available To understand the potential effects of forest policies on sustaining biological diversity at broad scales, we used spatial simulation models to evaluate current and potential future habitat availability over 100 yr for three focal species: Pacific Fisher (Martes pennanti, Pileated Woodpecker (Dryocopus pileatus, and Warbling Vireo (Vireo gilvus. The habitats of these species represent a broad range of spatial scales and forest types. Area of habitat for fishers and Pileated Woodpeckers is predicted to increase over time under current forest land management policies. Habitat for Warbling Vireos is predicted to decline. These patterns are consistent with past analyses that predicted declines in diverse early successional forests and hardwood forests and increases in late-successional forests under current and two alternative policies. Land ownership influenced the spatial arrangement of habitat for all three focal species. Public lands subsidized habitat for wide-ranging species on adjacent private lands. A land use policy that required greater green tree retention on private lands seemed to result in modest increases in habitat quality over 100 yr for Pileated Woodpeckers. Thinning of plantations on federal lands had little effect on these focal species. Policy analyses such as these highlight incongruities between historic habitat patterns and contemporary spatial and temporal scales of habitat in managed landscapes. This information can be used to assess risks and inform the policy debates surrounding biodiversity conservation.

  13. Forest Management as an Element of Environment Development (United States)

    Jaszczak, Roman; Gołojuch, Piotr; Wajchman-Świtalska, Sandra; Miotke, Mariusz


    The implementation of goals of modern forestry requires a simultaneous consideration of sustainable development of forests, protection, needs of the environment development, as well as maintaining a balance between functions of forests. In the current multifunctional forest model, rational forest management assumes all of its tasks as equally important. Moreover, its effects are important factors in the nature and environment protection. The paper presents legal conditions related to the definitions of forest management concepts and sustainable forest management. Authors present a historical outline of human's impact on the forest and its consequences for the environment. The selected aspects of forest management (eg. forest utilization, afforestation, tourism and recreation) and their role in the forest environment have been discussed.

  17. Artemisia: Active and Interactive Monitoring of the Forests in Protected Areas Aimed at the Sustainable Management of Nature

    Directory of Open Access Journals (Sweden)

    Clelia Cirillo


    Full Text Available To pursue the usage of forests resources in the processes of economic and social development it is determining that the principles of natural heritage protection join in a concept of progress, based on evolution and technological innovation; the realization of innovative investigation and representation tools turns out to be useful to ease the integration of forests’ resources in shared development processes aimed at enhancing the cooperation of local actors, and to ease the territory’s sustainable growth and the development of the natural heritage. The integrated management of the actions aimed at protecting and easing the ecologic and recreative functioning of forests, which are increasingly exposed to pressures caused by several catastrophic factors, requires the tuning of modelling and active monitoring systems of the forests based on social networks and volunteering for the processes of data updating.

  18. Public awareness of aesthetic and other forest values associated with sustainable forest management: a cross-cultural comparison among the public in four countries. (United States)

    Lim, Sang Seop; Innes, John L; Meitner, Michael


    Korea, China, Japan and Canada are all members of the Montreal Process (MP). However, there has been little comparative research on the public awareness of forest values within the framework of Sustainable Forest Management, not only between Asia and Canada, but also among these three Asian countries. This is true of aesthetic values, especially as the MP framework has no indicator for aesthetic values. We conducted surveys to identify similarities and differences in the perceptions of various forest values, including aesthetic values, between residents of the four countries: university student groups in Korea, China, Japan and Canada, as well as a more detailed assessment of the attitudes of Koreans by including two additional groups, Korean office workers, and Koreans living in Canada. A multivariate analysis of variance test across the four university student groups revealed significant differences in the rating of six forest functions out of 31. However the same test across the three Korean groups indicated no significant differences indicating higher confidence in the generalizability of our university student comparisons. For the forest aesthetic values, an analysis of variance test showed no significant differences across all groups. The forest aesthetic value was rated 6.95 to 7.98 (out of 10.0) depending on the group and rated relatively highly among ten social values across all the groups. Thurstone scale rankings and relative distances of six major forest values indicated that climate change control was ranked as the highest priority and scenic beauty was ranked the lowest by all the groups. Comparison tests of the frequencies of preferred major forest values revealed no significant differences across the groups with the exception of the Japanese group. These results suggest that public awareness of aesthetic and other forest values are not clearly correlated with the cultural backgrounds of the individuals, and the Korean university students' awareness

  4. Pre-Participation Medical Evaluation for Adventure and Wilderness Watersports. (United States)

    Nathanson, Andrew T; Young, Justin Mark J; Young, Craig


    A request for a preparticipation medical evaluation for wilderness watersports may be made by guiding agencies, instructional camps, or by patients presenting for an annual visit. Although guidelines have been published regarding preparticipation physical evaluation for traditional competitive high school and collegiate sports, little has been written about medical evaluations for those wishing to engage in wilderness and adventure watersports. in this article, we offer guidance based on literature review and expert opinion. Watersports are among the most common recreational activities in the United states and are generally safe. Drowning, however, is a significant risk, particularly in small, self-propelled craft, and among children. Medical counseling before participation in watersports should include screening for medical conditions which may impair swimming ability, including a history of seizures, heart disease, and lung disease. Physicians should also promote preventive health measures such as use of lifejackets and sun protection, as well as alcohol avoidance. Swim testing tailored to specific activities should be strongly considered for children and those with questionable swimming ability. Copyright © 2015. Published by Elsevier Inc.

  5. Active fans and grizzly bears: Reducing risks for wilderness campers (United States)

    Sakals, M. E.; Wilford, D. J.; Wellwood, D. W.; MacDougall, S. A.


    Active geomorphic fans experience debris flows, debris floods and/or floods (hydrogeomorphic processes) that can be hazards to humans. Grizzly bears ( Ursus arctos) can also be a hazard to humans. This paper presents the results of a cross-disciplinary study that analyzed both hydrogeomorphic and grizzly bear hazards to wilderness campers on geomorphic fans along a popular hiking trail in Kluane National Park and Reserve in southwestern Yukon Territory, Canada. Based on the results, a method is proposed to reduce the risks to campers associated with camping on fans. The method includes both landscape and site scales and is based on easily understood and readily available information regarding weather, vegetation, stream bank conditions, and bear ecology and behaviour. Educating wilderness campers and providing a method of decision-making to reduce risk supports Parks Canada's public safety program; a program based on the principle of user self-sufficiency. Reducing grizzly bear-human conflicts complements the efforts of Parks Canada to ensure a healthy grizzly bear population.

  7. Zoning of the Russian Federation territory based on forest management and forest use intensity

    Directory of Open Access Journals (Sweden)

    A. A. Маrtynyuk


    Full Text Available Over extended periods issues of forest management intensification are important in all aspects of Russian forest sector development. Sufficient research has been done in silviculture, forest planning and forest economics to address forest management intensification targets. Systems of our national territory forest management and forest economics zoning due to specifics of timber processing and forest area infrastructure have been developed. Despite sufficient available experience in sustainable forest management so far intensification issues were addressed due to development of new woodlands without proper consideration of forest regeneration and sustainable forest management operations. It resulted in forest resource depletion and unfavorable substitution of coniferous forests with less valuable softwood ones in considerable territories (especially accessible for transport. The situation is complicated since degree of forest ecosystem changes is higher in territories with high potential productivity. Ongoing changes combined with the present effective forest management system resulted in a situation where development of new woodlands is impossible without heavy investments in road construction; meanwhile road construction is unfeasible due to distances to timber processing facilities. In the meantime, changes in forest legislation, availability of forest lease holding, and promising post-logging forest regeneration technologies generate new opportunities to increase timber volumes due to application of other procedures practically excluding development of virgin woodlands. With regard to above, the Russian territory was zoned on a basis of key factors that define forest management and forest use intensification based on forest ecosystem potential productivity and area transport accessibility. Based on available data with GIS analysis approach (taking into consideration value of various factors the Russian Federation forest resources have been

  11. Long photoperiods sustain high pH in Arctic kelp forests

    DEFF Research Database (Denmark)

    Krause-Jensen, Dorte; Marbà, Núria; Sanz-Martin, M.


    Concern on the impacts of ocean acidification on calcifiers, such as bivalves, sea urchins, and foraminifers, has led to efforts to understand the controls on pH in their habitats, which include kelp forests and seagrass meadows. The metabolism of these habitats can lead to diel fluctuation in pH...... with increases during the day and declines at night, suggesting no net effect on pH at time scales longer than daily. We examined the capacity of subarctic and Arctic kelps to up-regulate pH in situ and experimentally tested the role of photoperiod in determining the capacity of Arctic macrophytes to up......-regulate pH. Field observations at photoperiods of 15 and 24 hours in Greenland com- bined with experimental manipulations of photoperiod show that photoperiods longer than 21 hours, characteristic of Arctic summers, are conducive to sustained up-regulation of pH by kelp photosynthesis. We report a gradual...

  17. How do migratory species add ecosystem service value to wilderness? Calculating the spatial subsidies provided by protected areas (United States)

    Lopez-Hoffman, Laura; Semmens, Darius J.; Diffendorfer, Jay


    Species that migrate through protected and wilderness areas and utilize their resources, deliver ecosystem services to people in faraway locations. The mismatch between the areas that most support a species and those areas where the species provides most benefits to society can lead to underestimation of the true value of protected areas such as wilderness. We present a method to communicate the “off-site” value of wilderness and protected areas in providing habitat to migratory species that, in turn, provide benefits to people in distant locations. Using northern pintail ducks (Anas acuta) as an example, the article provides a method to estimate the amount of subsidy – the value of the ecosystem services provided by a migratory species in one area versus the cost to support the species and its habitat elsewhere.

  20. Uncertainty in future water supplies from forests: hydrologic effects of a changing forest landscape (United States)

    Jones, J. A.; Achterman, G. L.; Alexander, L. E.; Brooks, K. N.; Creed, I. F.; Ffolliott, P. F.; MacDonald, L.; Wemple, B. C.


    Forests account for 33 percent of the U.S. land area, process nearly two-thirds of the fresh water supply, and provide water to 40 percent of all municipalities or about 180 million people. Water supply management is becoming more difficult given the increasing demand for water, climate change, increasing development, changing forest ownership, and increasingly fragmented laws governing forest and watershed management. In 2006, the US National Research Council convened a study on the present understanding of forest hydrology, the hydrologic effects of a changing forest landscape, and research and management needs for sustaining water resources from forested landscapes. The committee concluded that while it is possible to generate short-term water yield increases by timber harvesting, there are a variety of reasons why active forest management has only limited potential to sustainably increase water supplies. These include the short-term nature of the increases in most environments, the timing of the increases, the need for downstream storage, and that continuing ground- based timber harvest can reduce water quality. At the same time, past and continuing changes in forest structure and management may be altering water supplies at the larger time and space scales that are of most interest to forest and water managers. These changes include the legacy of past forest management practices, particularly fire suppression and clearcutting; exurban sprawl, which permanently converts forest land to nonforest uses; effects of climate change on wildfires, insect outbreaks, forest structure, forest species composition, snowpack depth and snowmelt; road networks; and changes in forest land ownership. All of these changes have the potential to alter water quantity and quality from forests. Hence, the baseline conditions that have been used to estimate sustained water yields from forested watersheds may no longer be applicable. Stationarity also can no longer be assumed for the

  1. Exploring Mechanisms for Effective Technology-Enhanced Simulation-based Education in Wilderness Medicine: A Systematic Review. (United States)

    MacKinnon, Ralph; Aitken, Deborah; Humphries, Christopher


     Technology-enhanced simulation is well-established in healthcare teaching curricula, including those regarding wilderness medicine. Compellingly, the evidence base for the value of this educational modality to improve learner competencies and patient outcomes are increasing.  The aim was to systematically review the characteristics of technology-enhanced simulation presented in the wilderness medicine literature to date. Then, the secondary aim was to explore how this technology has been used and if the use of this technology has been associated with improved learner or patient outcomes.  EMBASE and MEDLINE were systematically searched from 1946 to 2014, for articles on the provision of technology-enhanced simulation to teach wilderness medicine. Working independently, the team evaluated the information on the criteria of learners, setting, instructional design, content, and outcomes.  From a pool of 37 articles, 11 publications were eligible for systematic review. The majority of learners in the included publications were medical students, settings included both indoors and outdoors, and the main focus clinical content was initial trauma management with some including leadership skills. The most prevalent instructional design components were clinical variation and cognitive interactivity, with learner satisfaction as the main outcome.  The results confirm that the current provision of wilderness medicine utilizing technology-enhanced simulation is aligned with instructional design characteristics that have been used to achieve effective learning. Future research should aim to demonstrate the translation of learning into the clinical field to produce improved learner outcomes and create improved patient outcomes.

    Full Text Available The evolutions of the human society in past thirty years prove the necessity of an intervention to ensure a sustainable development. One of the most important principle of sustainability consist in preservation of natural resources and development of those activities, that can assure a real evolution of human society for a long period of time. The approach of aspects regarding to the situation of land, freshwater, biodiversity, atmosphere or forests can explain the real situation of environment and could help the economists find the best strategies for economic development. This goal of this article is to analyze the stage of present forestry resources and provide the reason for economists to take into account the limits in consumptions of environmental goods.

  8. Threats from urban expansion, agricultural transformation and forest loss on global conservation priority areas (United States)

    Moilanen, Atte; Di Minin, Enrico


    Including threats in spatial conservation prioritization helps identify areas for conservation actions where biodiversity is at imminent risk of extinction. At the global level, an important limitation when identifying spatial priorities for conservation actions is the lack of information on the spatial distribution of threats. Here, we identify spatial conservation priorities under three prominent threats to biodiversity (residential and commercial development, agricultural expansion, and forest loss), which are primary drivers of habitat loss and threaten the persistence of the highest number of species in the International Union for the Conservation of Nature (IUCN) Red List, and for which spatial data is available. We first explore how global priority areas for the conservation of vertebrate (mammals, birds, and amphibians) species coded in the Red List as vulnerable to each threat differ spatially. We then identify spatial conservation priorities for all species vulnerable to all threats. Finally, we identify the potentially most threatened areas by overlapping the identified priority areas for conservation with maps for each threat. We repeat the same with four other well-known global conservation priority area schemes, namely Key Biodiversity Areas, Biodiversity Hotspots, the global Protected Area Network, and Wilderness Areas. We find that residential and commercial development directly threatens only about 4% of the global top 17% priority areas for species vulnerable under this threat. However, 50% of the high priority areas for species vulnerable to forest loss overlap with areas that have already experienced some forest loss. Agricultural expansion overlapped with ~20% of high priority areas. Biodiversity Hotspots had the greatest proportion of their total area under direct threat from all threats, while expansion of low intensity agriculture was found to pose an imminent threat to Wilderness Areas under future agricultural expansion.

  10. Comparing modern and presettlement forest dynamics of a subboreal wilderness: Does spruce budworm enhance fire risk? (United States)

    Sturtevant, Brian R.; Miranda, Brian R.; Shinneman, Douglas J.; Gustafson, Eric J.; Wolter, Peter T.


    Insect disturbance is often thought to increase fire risk through enhanced fuel loadings, particularly in coniferous forest ecosystems. Yet insect disturbances also affect successional pathways and landscape structure that interact with fire disturbances (and vice-versa) over longer time scales. We applied a landscape succession and disturbance model (LANDIS-II) to evaluate the relative strength of interactions between spruce budworm (Choristoneura fumiferana) outbreaks and fire disturbances in the Boundary Waters Canoe Area (BWCA) in northern Minnesota (USA). Disturbance interactions were evaluated for two different scenarios: presettlement forests and fire regimes vs. contemporary forests and fire regimes. Forest composition under the contemporary scenario trended toward mixtures of deciduous species (primarily Betula papyrifera and Populus spp.) and shade-tolerant conifers (Picea mariana, Abies balsamea, Thuja occidentalis), with disturbances dominated by a combination of budworm defoliation and high-severity fires. The presettlement scenario retained comparatively more “big pines” (i.e., Pinus strobus, P. resinosa) and tamarack (L. laricina), and experienced less budworm disturbance and a comparatively less-severe fire regime. Spruce budworm disturbance decreased area burned and fire severity under both scenarios when averaged across the entire 300-year simulations. Contrary to past research, area burned and fire severity during outbreak decades were each similar to that observed in non-outbreak decades. Our analyses suggest budworm disturbances within forests of the BWCA have a comparatively weak effect on long-term forest composition due to a combination of characteristics. These include strict host specificity, fine-scaled patchiness created by defoliation damage, and advance regeneration of its primary host, balsam fir (A. balsamea) that allows its host to persist despite repeated disturbances.

  19. What are the forests worth? (United States)

    Fellows, L


    The Earth is a finite environment, thus growth cannot occur indefinitely. Eventually we will run out of space, resources, or anything else that is also finite. Once this fact is recognized, it becomes clear that we must develop in a sustainable way so that we can endure into the future. Overpopulation, vegetation destruction, and pollution are all serious threats to our finite environment. Traditionally, change has been to expensive and politically destabilizing. However, extensive changes in our modes of living must be made so that they become sustainable. In both developed and developing countries, consumptive growth must be replaced with sustainable development. Many developing countries are currently selling their natural resources to the developed countries. When they run out of resources, they will be truly poor. All governments must recognize the value of forests. It is estimated that in terms of medical uses for forest products alone, they will be worth US$11-12 billion (1990 dollars) by 2050. This constitutes a large portion of developing countries economies. Also, 80% of the population of developing countries rely on natural, traditional medicines made from forest products. Even in the US 25% of prescription drugs are based on phytochemicals. Now the drug companies are actively pursuing these resources for their products. It is estimated that 95% of the world species have not been assayed for their chemical value. Technology and money are not the obstacles to sustainable development and forest conservation. It is will and attitude that must be radically changed in order to protect the forests for the ecological and economic value.

  1. Increasing wood mobilization through Sustainable Forest Management in protected areas of Italy

    Directory of Open Access Journals (Sweden)

    Mauro Maesano


    Full Text Available Normal 0 14 false false false IT JA X-NONE The European Community has long recognized the need to further promote renewable energy. Under the overall objective to support and enhance sustainable management, the promotion of the use of forest biomass could help to mitigate climate change by substituting fossil fuel, increasing carbon stock in wood products and improve energy self-sufficiency enhancing security of supply and providing job opportunities in rural areas. To what extent Italian forests can satisfy an increased wood demand, without compromising the others Ecosystem Services (ESs remains an open question. Our aim was to assess the potential supply of woody biomass from the network of protected areas in Italy considering the felling constraints. We estimated the theoretical annual potential increment from forest inventory data performing a correlation with the Corine Land Cover 2006 at the IV level with a 1:100,000 resolution elaborated in a GIS (Geographic Information System environment. The average annual potential increment at national level available for felling was 4.4 m3ha-1. Within the network of protected areas (EUAP and Natura 2000, the average annual increment, available to felling, was 0.98 m3ha-1, respectively, 0.81 m3ha-1 from coppice and 1.14 m3ha-1 from non-coppice forests. Based on data obtained from this study, the availability of wood materials could be increased of almost 20 % at national level by pursuing an active management within the network of protected areas. In Italy, the actual level of resource utilization is rather low; increasing felling together with the implementation of an active management within protected areas could allow satisfying, theoretically, the Italian wood consumption. /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Tabella normale"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0

  2. Sustainable management indicators and implications of public policies for forestry

    International Nuclear Information System (INIS)

    Peyron, Jean-Luc; Bonheme, Ingrid


    Since 1995, in the framework of the Pan-European process of Ministerial Conferences on the Protection of Forests in Europe, every five years France establishes sustainable management indicators for forests in metropolitan France. The four successive publications now available provide information, according to the six criteria for sustainable forest management formulated in Helsinki in 1993, on developments over time in the state of French forests and the activities they generate. They also give rise to questions about the extent to which this follow-up meet the needs of forests in the area of public policies, including the fight against the greenhouse effect and adaptation to climate change. In addition, they suggest improvements for the short, medium and long term aimed at enhancing the switch from a statistical description to a strategic vision, as well as harmonisation and coherence of information, and extending the legal, political, institutional and geographic scope of sustainable forest management indicators.

    Canada contains 10% of the world's forests covering an area of 418 million hectares. The sustainable management of these forest resources has become increasingly complex. Hyperspectral remote sensing can provide a wealth of new and improved information products to resource managers to make more informed decisions. Research in this area has demonstrated that hyperspectral remote sensing can be used to create more accurate products for forest inventory, forest health, foliar biochemistry, biomass, and aboveground carbon than are currently available. This paper surveys recent methods and results in hyperspectral sensing of forests and describes space initiatives for hyperspectral sensing.

    In recent years strong concerns have been raised about the protection of the remaining areas of wilderness in Europe. Despite an extensive human footprint, Europe still retains large areas with a high degree of native and free functioning ecosystems, where roads, buildings, bridges, cables and other

  19. Tables of co-located geothermal-resource sites and BLM Wilderness Study Areas

    Foley, D.; Dorscher, M.


    Matched pairs of known geothermal wells and springs with BLM proposed Wilderness Study Areas (WSAs) were identified by inspection of WSA and Geothermal resource maps for the states of Arizona, California, Colorado, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington and Wyoming. A total of 3952 matches, for geothermal sites within 25 miles of a WSA, were identified. Of these, only 71 (1.8%) of the geothermal sites are within one mile of a WSA, and only an additional 100 (2.5%) are within one to three miles. Approximately three-fourths of the matches are at distances greater than ten miles. Only 12 of the geothermal sites within one mile of a WSA have surface temperatures reported above 50/sup 0/C. It thus appears that the geothermal potential of WSAs overall is minimal, but that evaluation of geothermal resources should be considered in more detail for some areas prior to their designation as Wilderness.

  20. Current Status and Problems in Certification of Sustainable Forest Management in China (United States)

    Zhao, Jingzhu; Xie, Dongming; Wang, Danyin; Deng, Hongbing


    Forest certification is a mechanism involving the regulation of trade of forest products in order to protect forest resources and improve forest management. Although China had a late start in adopting this process, the country has made good progress in recent years. As of July 31, 2009, 17 forest management enterprises and more than one million hectares of forests in China have been certified by the Forest Stewardship Council (FSC). Several major factors affect forest certification in China. The first set is institutional in nature. Forest management in China is based on centralized national plans and therefore lacks flexibility. A second factor is public awareness. The importance and value of forest certification are not widely understood and thus consumers do not make informed choices regarding certified forest products. The third major factor is the cost of certification. Together these factors have constrained the development of China's forest certification efforts. However, the process does have great potential. According to preliminary calculations, if 50% of China's commercial forests were certified, the economic cost of forest certification would range from US0.66-86.63 million while the economic benefits for the forestry business sector could exceed US150 million. With continuing progress in forest management practices and the development of international trade in forest products, it becomes important to improve the forest certification process in China. This can be achieved by improving the forest management system, constructing and perfecting market access mechanisms for certificated forest products, and increasing public awareness of environmental protection, forest certification, and their interrelationship.
