    The current global developments have the potential to cause a 'perfect storm' at the core of the Anthropocene: the Food-Energy-Water-Nexus. To discuss the ethical consequences of these developments, i.e., insufficient access to the life sustaining nexus resources, the analysis is focused on Rawls' theory of justice and its implementation in Germany with a special focus on the FEW nexus. Rawls stresses in his theory of justice the prominent meaning of institutions for a fair society to meet societal challenges and to meet the challenge of our time: a stable and just society. Hence, the realization of his ideas in Germany is scrutinized and income tax and value added tax are interpreted in the sense of Douglas North and John Rawls as institutions and formal rules of society. This paper focuses on taxes as the most important institutional incentive to organize and structure the political, social and economic cooperation and analyses how these incentives affect selected German households (all households, singles, single man and woman, and couples) with respect to income and FEW expenditures. The relevant income and usage data sample (Einkommens- und Verbrauchsstichprobe (EVS)) for Germany is used for the analysis of the distribution of income types, FEW expenditures and the revenues of income tax and value added tax, i.e., the main instruments to manage the challenges of the FEW nexus. Therefore two distribution measures have been used: the dispersion of income, taxes and FEW expenditures and their skewness. Five household groups were selected for this analysis: All households, all single households, the single women households, the single men households, as well as the households of couples. The EVS data sample allows the analysis of consequences of the current societal conditions on the various households and thus serves to provide a deeper understanding of the differences between singles and couples but also between single women and men.

    The water-energy-food (WEF) nexus is rapidly expanding in scholarly literature and policy settings as a novel way to address complex resource and development challenges. The nexus approach aims to identify tradeoffs and synergies of water, energy, and food systems, internalize social and environmental impacts, and guide development of cross-sectoral policies. However, while the WEF nexus offers a promising conceptual approach, the use of WEF nexus methods to systematically evaluate water, energy, and food interlinkages or support development of socially and politically-relevant resource policies has been limited. This paper reviews WEF nexus methods to provide a knowledge base of existing approaches and promote further development of analytical methods that align with nexus thinking. The systematic review of 245 journal articles and book chapters reveals that (a) use of specific and reproducible methods for nexus assessment is uncommon (less than one-third); (b) nexus methods frequently fall short of capturing interactions among water, energy, and food—the very linkages they conceptually purport to address; (c) assessments strongly favor quantitative approaches (nearly three-quarters); (d) use of social science methods is limited (approximately one-quarter); and (e) many nexus methods are confined to disciplinary silos—only about one-quarter combine methods from diverse disciplines and less than one-fifth utilize both quantitative and qualitative approaches. To help overcome these limitations, we derive four key features of nexus analytical tools and methods—innovation, context, collaboration, and implementation—from the literature that reflect WEF nexus thinking. By evaluating existing nexus analytical approaches based on these features, we highlight 18 studies that demonstrate promising advances to guide future research. This paper finds that to address complex resource and development challenges, mixed-methods and transdisciplinary approaches are needed

    Full Text Available The discourse on the need for water, energy, and food security has dominated the development agenda of southern African countries, centred on improving livelihoods, building resilience, and regional integration. About 60% of the population in the Southern African Development Community (SADC live in rural areas relying mainly on rainfed agriculture, lacking access to clean water and energy, yet the region is endowed with vast natural resources. The water-energy-food (WEF nexus is a conceptual framework that presents opportunities for greater resource coordination, management, and policy convergence across sectors. This is particularly relevant in the SADC region as resources are transboundary and supports efforts linked to regional integration and inclusive socio-economic development and security. We conducted an appraisal of WEF-related policies and institutions in SADC and identified linkages among them. The present ‘silo’ approach in resource management and allocation, often conducted at the national level, contributes to the region’s failure to meet its development targets, exacerbating its vulnerabilities. The lack of coordination of WEF nexus synergies and trade-offs in planning often threatens the sustainability of development initiatives. We highlighted the importance of the WEF nexus to sustainably address the sectoral coordination of resources through harmonised institutions and policies, as well as setting targets and indicators to direct and monitor nexus developments. We illustrate the significance of the nexus in promoting inclusive development and transforming vulnerable communities into resilient societies. The study recommends a set of integrated assessment models to monitor and evaluate the implementation of WEF nexus targets. Going forward, we propose the adoption of a regional WEF nexus framework.

    To prepare for future human space flight programs, the Mission Operations Laboratory (MOL) at the Marshall Space Flight Center (MSFC) has been investigating new planning and scheduling paradigms. To support and prove this investigation, MOL technologists have developed a working prototype of a scheduling system to support the new paradigms. The new planning and scheduling system is called Nexus and has a web site at http://nexus.nasa.gov/. Nexus is based on a comprehensive modeling schema to capture all scheduling requirements typical to human space missions, an incremental scheduling engine tailored to the modeling schema, and remote access (including Personal Data Assistant (PDA) access) to the scheduling system. This paper describes the proposed paradigm shift and the enabling software. It also describes a typical Nexus demonstration which emphasizes how it works, how it enables the paradigm shift, and possible applications. Demonstrations include access to the full functionally of Nexus from a personal computer and access to limited functionally via a PDA. An appendix includes a description and screen shots of the demonstrations.

    Water, energy, and agriculture are highly interdependent that attempts to achieve sustainability in any of those three domains will directly impact the others. These interdependencies, collectively known as the Water-Energy-Food Nexus, become more complex and more critical as the climate changes, the population grows, habits and lifestyles alternate, and the prices of water, energy, and food increase. However, and despite several attempts to incorporate the nexus, the global research community continues to focus on different subsets of the problem with limited holistic attempts to address the full problem. At best, interactions between two of the three domains were studied, often neglecting the impact of such interaction on the third domain. For example, agricultural researchers tracked water costs by applying concepts like virtual water or water footprint, or using large-scale system models to investigate food and water security, ignoring most often the corresponding energy footprint. Similarly, investigators quantified water-energy tradeoffs in the highly engineered, centralized systems of water and power management, paying no attention to water diversion from agriculture. Most nexus initiatives focused on reviews and data collection of existing knowledge and relevant facts, but unfortunately lacked a conceptual and mathematical framework that can integrate all the gathered knowledge and account for multiple interactions, feedbacks, or natural processes that occur across all three domains of the nexus. Here, we present an integrated conceptual and mathematical framework (roadmap) for the nexus. This framework is driven by spatiotemporal demands for water, energy, and food to be satisfied by resource management of the three domains, envisioned as a stepwise process, with each step requiring inputs from the three nexus domains and creating waste products. The efficiency of each step, combined with mass balances, create the linkages and feedback loops within the

    The water-food nexus is promoted as an approach to look at the linkages between water and food. The articles of Water’s Special Issue “Water-Energy-Food Nexus in Large Asian River Basins” look at the applicability of the nexus approach in different regions and rivers basins in Asia. Citarum River was selected for the case of Indonesia study site of RIHN Water-food Nexus Project with a focus on the Juanda/Jatiluhur dam as the downstream of the three large cascaded reservoirs and river estuary at the Jakarta Bay. As a result, there are a variety of interpretations for the nexus. These include three complementary perspectives that perceive nexus as an analytical approach, governance framework and emerging discourse. Secondly, nexus is a predominantly water-sector driven and water-centered concept. Evaluation of water quality of Citarum River and the increasing demands for water-food nexus revealed the critical status even at present condition that requires strategic decision to modify the water allocation policy to ensure human-environmental sustainability water security.

    Full Text Available This report summarizes the challenges of and requirements for effective governance of the water, energy and food nexus. With global dynamics such as climate change, urbanization and changing consumption patterns, governing resources in a coherent manner becomes both more complex and more relevant for sustainable development. Governance challenges include nexus economics (costs and benefits of different approaches to resource management, institutional design (like questions of how decision-making should be best distributed and good governance (how to make sure that nexus governance adheres to certain agreed upon principles and values. In terms of economics, a balance between sector specific actions and nexus governance is required. For effective decision-making it is important that power among different institutions is both distributed and coordinated. Good nexus governance requires targets that can be monitored to make sure that basic principles are followed and to examine whether progress toward sustainable development is being made.

    We propose a global network model to investigate the interdependence among the oil-equity nexuses from different countries in various time horizons based on wavelet coherence and gray correlation. The stock indexes from 28 countries and crude oil prices of WTI (​West Texas Intermediate price) and Brent are the sample. We obtain the following primary results: Oil-equity nexuses throughout the world are well-integrated across time scales; Ireland, the Netherlands, Norway, Singapore, Demark, Germany and the Czech Republic for Brent-stock nexuses and Ireland, the Netherlands, Netherlands, Singapore, Japan, Germany and Malaysia for WTI-stock nexuses, successively corresponding to the frequency bands of 4 days–256 days, can be treated as a benchmark and can spread their fluctuations to other nexuses easily and rapidly. By contrast, China is more isolated in most time horizons and could be the ideal risk-hedging choice. Next, the global interdependence among oil-stock nexuses is characterized by the clustering effect, by which geographical factors and the oil production-consumption profile can exert their influence in most time horizons. In contrast, the speculation deals as well as energy policy and stagey are primarily influential in certain frequency bands. Thus, the decision-making for different time horizons could consider corresponding references. - Highlights: • Global interactions among oil-stock nexuses are invested. • Interdependence among oil-stock nexuses for Brent and WTI are both integrated. • Oil-stock nexuses networks are characterized by Multiscale and cluster effecting.

    The term of water-energy -food nexus has gained increasing attention in the research and policy making communities as the security of water, energy and food becomes severe under changing environment. Ignorance of their closely interlinkages accompanied by their availability and service may result in unforeseeable, adverse consequences. This paper comprehensively reviews the state-of-the-art in the field of water-energy-food, with a focus on concepts, research questions and methodologies. First, two types of nexus definition are compared and discussed to understand the essence of nexus research issues. Then, three kinds of nexus research questions are presented, including internal relationship analysis, external impact analysis, and evaluation of the nexus system. Five nexus modelling approaches are discussed in terms of their advantages, disadvantages and application, with an aim to identify research gaps in current nexus methods. Finally, future research areas and challenges are discussed, including system boundary, data uncertainty and modelling, underlying mechanism of nexus issues and system performance evaluation. This study helps bring research efforts together to address the challenging questions in the nexus and develop the consensus on building resilient water, energy and food systems.

    Water, energy, and agriculture depend on each other so strongly that attempts to achieve sustainability in any of those three domains will directly impact the others. These interdependencies, collectively known as the Water-Energy-Food Nexus, become more complex and more critical as the climate changes, the population grows, habits and lifestyle alternatives, and the prices of water, energy, and food increase. The U.S. National Intelligence Council has identified the nexus of water, energy, food, and climate change as one of four overarching megatrends that will shape the world in 2030. However, the global research community has rarely addressed the full problem and focused instead on different subsets of the problem. For example, interactions between two of the three domains were studied, often neglecting the impact of such interaction on the third domain. Investigators have quantified water-energy tradeoffs in the highly engineered, centralized systems of water and power management. Agricultural researchers have tracked water costs by applying the concept of virtual water (the total volume of water needed to produce and process a commodity or service) or using large-scale system models to investigate food and water security.

  17. Nexusing Charcoal in South Mozambique: A Proposal To Integrate the Nexus Charcoal-Food-Water Analysis With a Participatory Analytical and Systemic Tool

    Directory of Open Access Journals (Sweden)

    2018-06-01

    Full Text Available Nexus analysis identifies and explores the synergies and trade-offs between energy, food and water systems, considered as interdependent systems interacting with contextual drivers (e.g., climate change, poverty. The nexus is, thus, a valuable analytical and policy design supporting tool to address the widely discussed links between bioenergy, food and water. In fact, the Nexus provides a more integrative and broad approach in relation to the single isolated system approach that characterizes many bioenergy analysis and policies of the last decades. In particular, for the South of Mozambique, charcoal production, food insecurity and water scarcity have been related in separated studies and, thus, it would be expected that Nexus analysis has the potential to provide the basis for integrated policies and strategies focused on charcoal as a development factor. However, to date there is no Nexus analysis focused on charcoal in Mozambique, neither is there an assessment of the comprehensiveness and relevance of Nexus analysis when applied to charcoal energy systems. To address these gaps, this work applies the Nexus to the charcoal-food-water system in Mozambique, integrating national, regional and international studies analysing the isolated, or pairs of, systems. This integration results in a novel Nexus analysis graphic for charcoal-food-water relationship. Then, to access the comprehensiveness and depth of analysis, this Nexus analysis is critically compared with the 2MBio-A, a systems analytical and design framework based on a design tool specifically developed for Bioenergy (the 2MBio. The results reveal that Nexus analysis is “blind” to specific fundamental social, ecological and socio-historical dynamics of charcoal energy systems. The critical comparison also suggests the need to integrate the high level systems analysis of Nexus with non-deterministic, non-prescriptive participatory analysis tools, like the 2MBio-A, as a means to

    The water-energy-food (WEF) nexus is rapidly expanding in scholarly literature and policy settings as a novel way to address complex Anthropocene challenges. The nexus approach aims to identify tradeoffs and synergies of water, energy, and food systems, internalize social and environmental impacts, and guide development of cross-sectoral policies. However, a primary limitation of the nexus approach is the absence - or gaps and inconsistent use - of adequate methods to advance an innovative and policy-relevant nexus approach. This paper presents an analytical framework to identify robust nexus methods that align with nexus thinking and highlights innovative nexus methods at the frontier. The current state of nexus methods was assessed with a systematic review of 245 journal articles and book chapters. This review revealed (a) use of specific and reproducible methods for nexus assessment is uncommon - less than one-third of the reviewed studies present explicit methods; (b) nexus methods frequently fall short of capturing interactions among water, energy, and food - the very concept they purport to address; (c) assessments strongly favor quantitative approaches - 70% use primarily quantitative tools; (d) use of social science methods is limited (26%); and (e) many nexus methods are confined to disciplinary silos - only about one-quarter combine methods from diverse disciplines and less than one-fifth utilize both quantitative and qualitative approaches. Despite some pitfalls of current nexus methods, there are a host of studies that offer innovative approaches to help quantify nexus linkages and interactions among sectors, conceptualize dynamic feedbacks, and support mixed method approaches to better understand WEF systems. Applying our analytical framework to all 245 studies, we identify, and analyze herein, seventeen studies that implement innovative multi-method and cross-scalar tools to demonstrate promising advances toward improved nexus assessment.

    NASA's Earth Observing System Data and Information System (EOSDIS) reports that over 15 petabytes (PB) of Earth observing information are archived among the 12 NASA Distributed Active Archive Centers (DAACs); with more being archived daily. The upcoming Surface Water & Ocean Topography (SWOT) mission is expected to generate about 26 PB of data in 3 years. NEXUS is a state of the art deep data analytic program developed at the Jet Propulsion Laboratory with the goal of providing near real-time analytic capabilities for this vast trove of data. Rather than develop analytic services on traditional file archives, NEXUS organizes data into tiles in order to provide a platform for horizontal computing. To provide near real-time analytic solutions for missions such as SWOT, a highly scalable data ingestion solution is developed to quickly bring data into NEXUS. In order to accomplish this formidable challenge, the "Four V's" (Volume, Velocity, Veracity, and Variety) of Big Data must be considered. NEXUS consists of an ingestion subsystem that handles the Volume of data by utilizing a generic tiling strategy that subsets a given dataset into smaller tiles. These tiles are then indexed by a search engine and stored in a NoSQL database for fast retrieval. In addition to handling the Volume of data being indexed, the NEXUS ingestion subsystem is built for horizontal scalability in order to manage the Velocity of incoming data. As the load on the system increases, the components of the ingestion subsystem can be scaled to provide more capacity. During ingestion, NEXUS also takes a unique approach to the Veracity and Variety of Earth observing information being ingested. By allowing the processing and tiling mechanisms to be customized for each dataset, the NEXUS ingest system can discard erroneous or missing data as well as adapt to the many different data structures and file formats that can be found in satellite observation data. This talk will focus on the functionality and

    The needs to consider the NEXUS on food and water were emphasized in international dialogues and publications around the end of the 20th century. In fact, in 1983, the United Nations University already launched a Food-Energy Nexus Programme to fill the gaps between the issues of food and energy. The term "NEXUS" to link water, food, and trade was also used in the World Bank during 1990s. The idea of NEXUS is likely to have further developed under the discussion of "virtual water" and "water footprints". With experiencing several international discussions such as Kyoto World Water Forum 2003, scholars and practitioners around the globe acknowledged the need to include energy for the pillars of NEXUS. Finally, the importance of three NEXUS pillars, "water, energy, and food" was officially announced in the BONN 2011 NEXUS Conference, which is a turning point of NEXUS idea in the international community , in order to contribute to the United Nations Conference on Sustainable Development (Rio+20) in 2012 that highlighted the concept of "green economy". The concept of NEXUS is becoming a requisite to achieve sustainable development due to the global concerns embedded in society, economy, and environment. The concept stresses to promote the cooperation with the sectors such as water, energy, food, and climate change since these complex global issues are dependent and inter-connected, which can no longer be solved by the sectorial approaches. The NEXUS practices are currently shared among different stakeholders through various modes including literatures, conferences, workshops, and research projects. However, since the NEXUS practices are not led by a particular organization, its concept, theory, policy, tools, methods, and applications are diverse and incoherent. In terms of tools/methods, the potential of integrated modeling approach is introduced to avoid pressures and to promote interactions among water, energy and food. This paper explores the concepts, tools

    Analysis the water-food-energy nexus is the first step to assess the decision maker in developing and evaluating national strategies that take into account the nexus. The main objective of the current research is providing a method for the decision makers to analysis the water-food-energy nexus of the crop production system at the national level and carrying out a quantitative assessment of it. Through the proposed method, indicators considering the water and energy consumption, mass productivity, and economic productivity were suggested. Based on these indicators a water-food-energy nexus index (WFENI) was performed. The study showed that the calculated WFENI of the Egyptian summer crops have scores that range from 0.21 to 0.79. Comparing to onion (the highest scoring WFENI,i.e., the best score), rice has the lowest WFENI among the summer food crops. Analysis of the water-food-energy nexus of forty-two Egyptian crops in year 2010 was caried out (energy consumed for irrigation represent 7.4% of the total energy footprint). WFENI can be applied to developed strategies for the optimal cropping pattern that minimizing the water and energy consumption and maximizing their productivity. It can be applied as a holistic tool to evaluate the progress in the water and agricultural national strategies. Moreover, WFENI could be applied yearly to evaluate the performance of the water-food-energy nexus managmant.

    Water, energy and food (WEF) are inextricably interrelated. Effective planning and management of limited WEF resources to meet current and future socioeconomic demands for sustainable development is challenging. WEF production/delivery may also produce environmental impacts; as a result, green-house-gas emission control will impact WEF nexus management as well. Nexus management for WEF security necessitates integrated tools for predictive analysis that are capable of identifying the tradeoffs among various sectors, generating cost-effective planning and management strategies and policies. To address these needs, we have developed an integrated model analysis framework and tool called WEFO. WEFO provides a multi-period socioeconomic model for predicting how to satisfy WEF demands based on model inputs representing productions costs, socioeconomic demands, and environmental controls. WEFO is applied to quantitatively analyze the interrelationships and trade-offs among system components including energy supply, electricity generation, water supply-demand, food production as well as mitigation of environmental impacts. WEFO is demonstrated to solve a hypothetical nexus management problem consistent with real-world management scenarios. Model parameters are analyzed using global sensitivity analysis and their effects on total system cost are quantified. The obtained results demonstrate how these types of analyses can be helpful for decision-makers and stakeholders to make cost-effective decisions for optimal WEF management.

    2017-12-01

    The objective of this study is to design and visualize a water-energy-food nexus system to identify the interrelationships between water-energy-food (WEF) resources and to understand the subsequent complexity of WEF nexus systems holistically, taking an interdisciplinary approach. Object-oriented concepts and ontology engineering methods were applied according to the hypothesis that the chains of changes in linkages between water, energy, and food resources holistically affect the water-energy-food nexus system, including natural and social systems, both temporally and spatially. The water-energy-food nexus system that is developed is significant because it allows us to: 1) visualize linkages between water, energy, and food resources in social and natural systems; 2) identify tradeoffs between these resources; 3) find a way of using resources efficiently or enhancing the synergy between the utilization of different resources; and 4) aid scenario planning using economic tools. The paper also discusses future challenges for applying the developed water-energy-food nexus system in other areas.

    The water, energy and food nexus (WEF nexus) is currently quite popular in environmental management. The concept found a fertile ground in science and policymaking, but there is no consistent view on the meaning of integration within the nexus. Here, a wealth of publications is reviewed in an endeavour to: (1) reveal the lines of justification for the need of the WEF nexus debate and (2) identify the range of tools for analysing the interdependent resource issues of the nexus using an integrated framework of science and policy. There are three drivers behind the emergence of the nexus thinking. These are a) increasing resource interlinks due to growing scarcities, b) recent resource supply crises, and c) failures of sector-driven management strategies. Evaluation of the WEF nexus integrative debate can be carried out using four key criteria, namely ability to change current policy debates, issue and thinking novelty, practicability and measurability, and clearness and implementation roadmap. It is clear that, although the nexus has been quite successful in changing policy debates, issue prioritization is missing and seems to be left to specific case studies and policymakers' choices. There is a high need for 'incorporation' and 'cross-linking' of issues between the three resources. In this regard, nexus governance is the missing link in the nexus debate.

    Cautun, Marius; van de Weygaert, Rien; Jones, Bernard J. T.

    2013-02-01

    We introduce the NEXUS algorithm for the identification of cosmic web environments: clusters, filaments, walls and voids. This is a multiscale and automatic morphological analysis tool that identifies all the cosmic structures in a scale free way, without preference for a certain size or shape. We develop the NEXUS method to incorporate the density, tidal field, velocity divergence and velocity shear as tracers of the cosmic web. We also present the NEXUS+ procedure which, taking advantage of a novel filtering of the density in logarithmic space, is very successful at identifying the filament and wall environments in a robust and natural way. To assess the algorithms we apply them to an N-body simulation. We find that all methods correctly identify the most prominent filaments and walls, while there are differences in the detection of the more tenuous structures. In general, the structures traced by the density and tidal fields are clumpier and more rugged than those present in the velocity divergence and velocity shear fields. We find that the NEXUS+ method captures much better the filamentary and wall networks and is successful in detecting even the fainter structures. We also confirm the efficiency of our methods by examining the dark matter particle and halo distributions.

    The interactions between the food, energy and water sectors are of great importance to urban sustainable development. This work presents a framework to analyze food-energy-water (FEW) nexus of a city. The method of multi-scale input-output analysis is applied to calculate consumption-based energy and water use that is driven by urban final demand. It is also capable of accounting virtual energy and water flows that is embodied in trade. Some performance indicators are accordingly devised for a comprehensive understanding of the urban FEW nexus. A case study is carried out for the Beijing city. The embodied energy and water use of foods, embodied water of energy industry and embodied energy of water industry are analyzed. As a key node of economic network, Beijing exchanges a lot of materials and products with external economic systems, especially other Chinese provinces, which involves massive embodied energy and water flows. As a result, Beijing relies heavily on outsourcing energy and water to meet local people's consumption. It is revealed that besides the apparent supply-demand linkages, the underlying interconnections among food, water and energy sectors are critical to create sustainable urban areas.

  8. Balancing the Energy-Water Nexus

    Optimizing the complex tradeoffs in the Energy-Water Nexus requires quantification of energy use, carbon emitted and water consumed. Water is consumed in energy production and is often a constraint to operations. More global attention and investment has been made on reducing carbon emissions than on water management. Review of public reporting by the largest 107 global power producers and 50 companies in the oil/gas industry shows broad accounting on carbon emissions but only partial reporting on water consumption metrics. If the Energy-Water Nexus is to be balanced, then water must also be measured to be optimally managed with carbon emissions.

    Full Text Available Sustaining the water-energy-food nexus for the future requires new governance approaches and joint management across sectors. The challenges to the implementation of the nexus are many, but not insurmountable. These include trade-offs between sectors, difficulties of communication across the science-policy interface, the emergence of new vulnerabilities resulting from implementation of policies, and the perception of high social and economic costs. In the context of the Sustainability in the W-E-F Nexus conference May 19-20, 2014, the session on ‘Governance and Management of the Nexus: Structures and Institutional Capacities’ discussed these problems as well as tools and solutions to nexus management. The session demonstrated three key findings: 1. Trade-offs in the Water-Energy-Food Nexus should be expanded to include the varied and shifting social and power relations; 2. Sharing knowledge between users and policy makers promotes collective learning and science-policy-stakeholder communication; and 3. Removing subsidies or seeking the ‘right price’ for domestic resources vis à vis international markets is not always useful; rather the first imperative is to gauge current and future costs at the national scale.

    2016-12-01

    Water, energy, and food are the most essential and fundamental resources for human well-beings, a sustainable society, and global sustainability. These are inextricably linked, and there are complex synergies and tradeoffs among the three resources. More issues arise and attention must be paid when it comes to the Water-Energy-Food (WEF) Nexus. Lack of integrated research between a nexus and policy implementation is the most concerning. The United Nations Sustainable Development Goals (SDGs) aim to end poverty, protect the planet, and ensure prosperity for all, and are scheduled to be achieved by 2030. Of the 17 SDGs, Goal 2, 6 and 7 are directly related to food, water, and energy sectors. However, there are no integrated SDGs related to the Water-Energy-Food Nexus. Two different directions of nexus research exist in developing and industrialized worlds, and synthesis of both are needed. Developing countries are striving to increase their Human Development Index (HDI) while keeping Ecological Footprints, including Nexus Footprint, low. On the other hand, industrialized countries are targeting to maintain their high HDI and reduce their Ecological Footprints. Both are challenging tasks under the restrictions of planetary boundaries (limited nature) and doughnut economy (limited society). In this study, WEF Nexus research in Asian countries, including developing and industrialized countries, demonstrates the different types of nexus approaches to achieve SDGs through renewable energy, agriculture and aquaculture as food, and water management in Monsoon and semi-arid Asia. Mutual learning between the two types of nexus approaches can be made in the Asian area.

  14. Dynamical resource nexus assessments: from accounting to sustainability approaches

    Science.gov (United States)

    Salmoral, Gloria; Yan, Xiaoyu

    2017-04-01

    Continued economic development and population growth result in increasing pressures on natural resources, from local to international levels, for meeting societal demands on water, energy and food. To date there are a few tools that link models to identify the relationships and to account for flows of water, energy and food. However, these tools in general can offer only a static view often at national level and with annual temporal resolution. Moreover, they can only account flows but cannot consider the required amounts and conditions of the natural capital that supplies and maintains these flows. With the emerging nexus thinking, our research is currently focused on promoting dynamical environmental analyses beyond the conventional silo mentalities. Our study aims to show new advancements in existing tools (e.g., dynamical life cycle assessment) and develop novel environmental indicators relevant for the resource nexus assessment. We aim to provide a step forward when sustainability conditions and resilience thresholds are aligned with flows under production (e.g., food, water and energy), process level under analysis (e.g., local production, transport, manufacturing, final consumption, reuse, disposal) and existing biophysical local conditions. This approach would help to embrace and better characterise the spatiotemporal dynamics, complexity and existing links between and within the natural and societal systems, which are crucial to evaluate and promote more environmentally sustainable economic activities.

    Full Text Available Understanding complex phenomena such as the water-energy-food nexus (resource nexus requires a more holistic, interdisciplinary inquiry. Spurred by a sense of imbalance in approaches to the nexus dominated by integrated assessment/complex systems methodologies, I re-examine the findings and recommendations of a major 'nexus' research-for-development project in the Mekong region. The concept of 'regime of provisioning', a synthesis of social science concepts related to meso-level social order, allows essential political economy and discursive elements of the resource nexus to be analysed. I show that socio-political regimes constrain societal investment in three 'nodes' of the nexus previously identified as critical to manage sustainably: energy efficiency, wild-capture fisheries, and diversified smallholder agriculture. I discuss implications for the 'nexus' as a new policy agenda and offer three propositions for ongoing inquiry and inclusive practice.

    2015-10-01

    Full Text Available This paper focuses on a collection of methods that can be used to analyze the water-energy-food (WEF nexus. We classify these methods as qualitative or quantitative for interdisciplinary and transdisciplinary research approaches. The methods for interdisciplinary research approaches can be used to unify a collection of related variables, visualize the research problem, evaluate the issue, and simulate the system of interest. Qualitative methods are generally used to describe the nexus in the region of interest, and include primary research methods such as Questionnaire Surveys, as well as secondary research methods such as Ontology Engineering and Integrated Maps. Quantitative methods for examining the nexus include Physical Models, Benefit-Cost Analysis (BCA, Integrated Indices, and Optimization Management Models. The authors discuss each of these methods in the following sections, along with accompanying case studies from research sites in Japan and the Philippines. Although the case studies are specific to two regions, these methods could be applicable to other areas, with appropriate calibration.

    2014-12-01

    The joint security of water, food, and energy systems is an urgent issue everywhere, and strong drivers of development and land use change, exacerbated by climate change, require new knowledge to achieve integrated solution using a nexus-based approach to assess inter-dependencies. Effective research-based decision support tools are essential to identify the major issues and interconnections to help in implementation of the nexus approach. The major needs are models and data to clearly and unambiguously present decision scenarios to local cooperative groups of farmers, electric energy generators and water officials for joint decisions. These can be developed by integrated models to link hydrology, land use, energy use, cropping simulation, and optimization with economic objectives and socio-physical constraints. The first step in modeling is to have a good conceptual model and then to get data. As the linking of models increases uncertainties, each one should be supplied with adequate data at suitable spatial and temporal resolutions. Most models are supplied with data by geophysical scientists, such as hydrologists, geologists, atmospheric scientists, soil scientists, and climatologists, among others. Outcomes of a recently-completed project to study the water-energy-food nexus will be explained to illuminate the model and data needs to inform future management actions across the nexus. The project included a workshop of experts from government, business, academia, and the non-profit sector who met to define and explain nexus interactions and needs. An example of the findings is that data inconsistencies among sectors create barriers to integrated planning. A nexus-based systems model is needed to outline sectoral inter-dependencies and identify data demands and gaps. Geophysical scientists can help to create this model and take leadership on designing data systems to facilitate sharing and enable integrated management.

    Jacob, J. C.; Huang, T.; Lynnes, C.

    2016-12-01

    NEXUS is an emerging data-intensive analysis framework developed with a new approach for handling science data that enables large-scale data analysis. It is available through open source. We compare performance of NEXUS and Giovanni for 3 statistics algorithms applied to NASA datasets. Giovanni is a statistics web service at NASA Distributed Active Archive Centers (DAACs). NEXUS is a cloud-computing environment developed at JPL and built on Apache Solr, Cassandra, and Spark. We compute global time-averaged map, correlation map, and area-averaged time series. The first two algorithms average over time to produce a value for each pixel in a 2-D map. The third algorithm averages spatially to produce a single value for each time step. This talk is our report on benchmark comparison findings that indicate 15x speedup with NEXUS over Giovanni to compute area-averaged time series of daily precipitation rate for the Tropical Rainfall Measuring Mission (TRMM with 0.25 degree spatial resolution) for the Continental United States over 14 years (2000-2014) with 64-way parallelism and 545 tiles per granule. 16-way parallelism with 16 tiles per granule worked best with NEXUS for computing an 18-year (1998-2015) TRMM daily precipitation global time averaged map (2.5 times speedup) and 18-year global map of correlation between TRMM daily precipitation and TRMM real time daily precipitation (7x speedup). These and other benchmark results will be presented along with key lessons learned in applying the NEXUS tiling approach to big data analytics in the cloud.

  2. Imperialism and Financialism: A Story of a Nexus

    Directory of Open Access Journals (Sweden)

    Shimshon Bichler

    2012-03-01

    Full Text Available Over the past century, the nexus of imperialism and financialism has become a major axis of Marxist theory and praxis. Many Marxists consider this nexus to be a cause of worldly ills, but the historical role they ascribe to it has changed dramatically over time. The key change concerns the nature and direction of surplus and liquidity flows. The first incarnation of the nexus, articulated at the turn of the twentieth century, explained the imperialist scramble for colonies to which finance capital could export its ‘excessive’ surplus. The next version posited a neo-imperial world of monopoly capitalism where the core’s surplus is absorbed domestically, sucked into a ‘black hole’ of military spending and financial intermediation. The third script postulated a World System where surplus is imported from the dependent periphery into the financial core. And the most recent edition explains the hollowing out of the U.S. core, a ‘red giant’ that has already burned much of its own productive fuel and is now trying to ‘financialize’ the rest of the world in order to use the system’s external liquidity. This paper outlines this chameleon-like transformation, assesses what is left of the nexus and asks whether it is worth keeping.

  3. Scaling and contextualizing climate-conflict nexus in historical agrarian China

    Science.gov (United States)

    Lee, Harry F.

    2017-04-01

    This study examines climate-conflict nexus in historical agrarian China in multi-scalar and contextualized approach, illustrating what and how socio-political factors could significantly mediate the climate-violent link in pre-industrial society. Previous empirical large-N studies show that violent conflict in historical agrarian society was triggered by climate-induced food scarcity. The relationship was valid in China, Europe, and various geographic regions in the Northern Hemisphere in pre-industrial era. Nevertheless, the observed relationship has only been verified at a macro level (long-term variability of the nexus is emphasized and data over large area are aggregated), and somewhat generalized in nature (only physical environmental factors are controlled). Three inter-related issues remain unresolved: First, the key explanatory variable of violent conflicts may change substantially at different spatio-temporal scales. It is necessary to check whether the climate-conflict nexus is valid at a micro level (about short-term variability of the nexus and data in finer spatial resolution), and explore how the nexus changes along various spatio-temporal dimensions. Second, as the climate-conflict nexus has only been demonstrated in a broad sense, it is necessary to check whether and how the nexus is mediated by local socio-political context. More non-climatic factors pertinent to the cause and distribution of conflicts (e.g., governance, adaptive mechanisms, etc.) should be considered. Third, the methodology applied in the previous studies assumes spatially-independent observations and linear relationship, which may simplify the climate-conflict link. Moreover, the solitary reliance on quantitative methods may neglect those non-quantifiable socio-political dynamics which mediates the climate-conflict nexus. I plan to address the above issues by using disaggregated spatial analysis and in-depth case studies, with close attention to local and temporal differences and

  4. Corporate Governance and Financial Performance Nexus: Any Bidirectional Causality?

    Directory of Open Access Journals (Sweden)

    Alley Ibrahim S.

    2016-06-01

    Full Text Available Most studies on corporate governance recognize endogeneity in the nexus between corporate governance and financial performance. Little attention has, however, been paid to the direction of causality between the two phenomena, and hence the Vector Error Correction (VEC model, which allows for endogenous determination of the direction of causality, has not been widely employed. This study fills that gap by estimating the nexus and the direction of causality using the VEC model to analyze panel data on selected listed firms in Nigeria. The results agree with the findings of most previous studies that corporate governance significantly affects financial performance. Board skills, board composition and management skills enhanced financial performance indicators – return on equity (ROE, return on asset (ROA and net profit margin (NPM; in many occasions, significantly. Board size and audit committee size did not, and can actually undermine financial performance. More importantly, financial performance did not significantly affect corporate governance. On the basis of the lag structure of the VEC model, this study affirms unidirectional causality in the nexus, running from corporate governance to financial performance, nullifying the hypothesis of bidirectional causality in the nexus.

    Directory of Open Access Journals (Sweden)

    2015-02-01

    Full Text Available The nexus is still very much an immature concept. Although it is difficult to disagree with a vision of integration between water, food and energy systems, there are fewer consensuses about what it means in reality. While some consider its framing to be too restrictive (excluding climate change and nature, particular actors see it as linked to green economy and poverty reduction, while others emphasise global scarcity and value chain management. The nexus debates, however, mask a bigger debate on resource inequality and access, contributing to social instability. Indeed, the market-technical framing of the nexus by the World Economic Forum, located in international business imperatives and global neoliberal policy hides political issues such as inequality, the manufacture of scarcity and international political economy and geopolitics. By addressing these, we then propose a new framing of the nexus.

    Renewable energies are considered as an essential element of any strategy for sustainable energy development. The poor in the developing world without access to modern energies are regarded as a major market for renewable energies. This short paper attempts to analyse whether such a niche is backed by any economic logic and whether renewable energy and the poor nexus could be a strategy for success. The paper suggests that contrary to the common belief, the economic logic behind the niche is unsound and that the nexus is not a recipe for success

    Water, energy, and food are the most important and fundamental resources for human beings and society. Demands for these resources are escalating rapidly because of increases in populations and changes in lifestyles. Therefore intensive demand for those resources makes conflicts between resources. Securities of water, energy, and food are treated separately, however they should be considered as one integrated matter, because water-energy-food are connected and it makes nexus and tradeoff. Security in terms of self-production, diversity of alternatives, and variability are evaluated for water, energy and food for thirty two countries in the Asia-Pacific region. The water and energy nexus includes water consumption for the cooling of power plant systems, water use for hydro power generation, and energy consumption for water allocation and pumping. The water and food nexus consists of water consumption for agriculture and aquaculture. The energy and food nexus includes energy consumption for food production and biomass for energy. Analyses of 11 countries within the Asia- Pacific region show that energy consumption for fish is the largest among foods in Japan, Philippines, and Peru, while energy consumption for cereals is the largest among foods in Canada, US, Indonesia, and others. Water consumption for different types of food and energy are also analyzed, including nexus ratio to total water consumption. The water-energy-food nexus at a local level in the Asia Pacific region are examined by the Research Institute for Humanity and Nature project "Human environmental security in Asia Pacific Ring of Fire". Themes including geothermal power plants for energy development and hot springs as water, shale gas for energy development and water consumption/contamination, aquaculture for food and water contamination are used to evaluate the water-energy-food nexus in the Asia-Pacific region.

    A four-year EU H2020 project "Sustainable Integrated Management FOR the NEXUS of water-land-food-energy-climate for a resource-efficient Europe (SIM4NEXUS)" started in June 2016, with an overall grant of € 7.9M (www.sim4nexus.eu). The project involves 25 partners from 15 European countries. SIM4NEXUS has four objectives: (i) to adopt existing knowledge and develop new expertise on the water-energy-food-climate-land use Nexus; (ii) to reduce uncertainties of how policies, governance and institutions affect complex environmental systems; (iii) to showcase the implementation via a network of three regional, five national, two transboundary case studies in Europe, as well as continental and global studies; (iv) to valorise the project outputs by suitable business models. SIM4NEXUS develops an innovative concept and methodologies to facilitate the design of policies and bridge knowledge and technology gaps in the field of the Nexus under global change. The project will develop a methodology of integration using a complexity science approach and a Serious Game (a decision-based platform that allows policy makers to play out scenarios to see what would bring the best outcome) as an integrating tool for testing and evaluating policy decisions. The Serious Game is based on Aqua Republica (http://www.dhigroup.com/upload/publications/scribd/172629015-Exploring-the-World-of-Aqua-Republica-DHI-Case-Story.pdf ) and will cover a vast array of scenarios for all the case studies, over short, medium and long terms. In this presentation we focus on all the stages of the development of the Serious Game for one of our Case Studies (Sardinia, Italy) which is being used as a pilot example prior to wider rollout. Specifically we detail the components and steps involved in Game development including: (i) linking thematic models (CAPRI- http://www.capri-model.org/dokuwiki/doku.php and E3ME- http://www.e3me.com/) and downscaling to regional level; (ii) climate change scenarios (using and

    Climate change and economic development are causing increased pressure on water, energy and food resources, presenting communities with increased levels of tradeoffs and potential conflicts among these resources. Therefore, the water-energy-food nexus is one of the most important and fundamental global environmental issues facing the world. For the purposes of this research project, we define human-environmental security as the joint optimization between human and environmental security as well as the water-energy-food nexus. To optimize the governance and management within these inter-connected needs, it is desirable to increase human-environmental security by improving social managements for the water-energy-food nexus. In this research project, we intend to establish a method to manage and optimize the human-environmental security of the water-energy-food nexus by using integrated models, indices, and maps as well as social and natural investigations with stakeholder analyses. We base our approach on the viewpoint that it is important for a sustainable society to increase human-environmental security with decreasing risk and increasing resilience by optimizing the connections within the critical water-energy and water-food clusters. We will take a regional perspective to address these global environmental problems. The geological and geomorphological conditions in our proposed study area are heavily influenced by the so-called 'Ring of Fire,' around the Pacific Ocean. Within these areas including Japan and Southeast Asia, the hydro-meteorological conditions are dominated by the Asia monsoon. The populations that live under these natural conditions face elevated risk and potential disaster as negative impacts, while also benefitting from positive ecological goods and services. There are therefore tradeoffs and conflicts within the water-energy-food nexus, as well as among various stakeholders in the region. The objective of this project is to maximize human

    Full Text Available The Southern African Development Community’s (SADC water and energy sectors are under increasing pressure due to population growth and agricultural and industrial development. Climate change is also negatively impacting on the region’s water and energy resources. As the majority of SADC’s population lives in poverty, regional development and integration are underpinned by water and energy security as the watercourses in the region are transboundary in nature. This paper reviews the region’s water and energy resources and recommends policies based on the water–energy nexus approach. This is achieved by reviewing literature on water and energy resources as well as policy issues. Water resources governance provides a strong case to create a water–energy nexus platform to support regional planning and integration as SADC countries share similar climatic and hydrological conditions. However, there has been a gap between water and energy sector planning in terms of policy alignment and technical convergence. These challenges hinder national policies on delivering economic and social development goals, as well as constraining the regional goal of greater integration. Regional objectives on sustainable energy and access to clean water for all can only be achieved through the recognition of the water–energy nexus, championed in an integrated and sustainable manner. A coordinated regional water–energy nexus approach stimulates economic growth, alleviates poverty and reduces high unemployment rates. The shared nature of water and energy resources requires far more transboundary water–energy nexus studies to be done in the context of regional integration and policy formulation.

    Economic development, population growth, and the changing diets and lifestyles of a growing middle class are expected to lead to increasing demands for water, food, and energy in the future. Meanwhile, climate change may cause localized resource scarcity and exacerbate the supply challenges. Moreover, there is a growing awareness that the supply systems for water, food, and energy are inextricably linked and cannot be evaluated in independent silos. Rather, integrated approaches are needed that can identify the potential trade-offs and synergies among sectors, identify holistic solutions, and evaluate the impacts of socioeconomic and hydroclimatic change. Some initial efforts at modeling the energy-water-food nexus in an integrated fashion have been attempted, but they all suffer from limitations and much more research is needed. This study provides a review of the current state-of-the-art in modeling the energy-water-food nexus at both global and regional scales, identifies limitations associated with existing approaches, and proposes specific recommendations for improving nexus assessments. Some limitations of existing models include insufficient spatial resolution for assessing water constraints in the energy sector, inadequate representation of the linkages among sectors, limited assessment of the impacts of socioeconomic and hydroclimatic change, limited inclusion of water conveyance, simplistic downscaling of water and energy demands, and the lack of a consistent framework for global nexus assessment. In addition, research gaps are identified by graphically classifying existing nexus assessments according to their spatial resolution, coverage of nexus sectors and linkages, and suitability for assessing the main drivers of global change (e.g., development, urbanization, technology, and climate change). The final portion of the study proposes recommendations for addressing the research gaps and identifies tremendous opportunity for developing better models and

    Indian agriculture is trapped in a complex nexus of groundwater depletion and energy subsidies. This nexus is the product of past public policy choices that initially offered opportunities to India's small-holder-based irrigation economy but has now generated in its wake myriad economic, social, and environmental distortions. Conventional `getting-the-price-right' solutions to reduce these distortions have consistently been undermined by the invidious political economy that the nexus has created. The historical evolution of the nexus is outlined, the nature and scale of the distortions it has created are explored, and alternative approaches which Indian policy makers can use to limit, if not eliminate, the damaging impacts of the distortions, are analysed.

    Water, food and energy are the most essential natural resources needed to sustain life. Water-Food-Energy Nexus (WFE Nexus) has nowadays caught global attention upon natural resources scarcity and their interdependency. In the past decades, Taiwan's integrative development has undergone drastic changes due to population growth, urbanization and excessive utilization of natural resources. The research intends to carry out interdisciplinary studies on WFE Nexus based on data collection and analysis as well as technology innovation, with a mission to develop a comprehensive solution to configure the synergistic utilization of WFE resources in an equal and secure manner for building intelligent dynamic green cities. This study aims to establish the WFE Nexus through interdisciplinary research. This study will probe the appropriate and secure resources distribution and coopetition relationship by applying and developing techniques of artificial intelligence, system dynamics, life cycle assessment, and synergy management under data mining, system analysis and scenario analysis. The issues of synergy effects, economic benefits and sustainable social development will be evaluated as well. First, we will apply the system dynamics to identify the interdependency indicators of WFE Nexus in response to urbanization and build the dynamic relationship among food production, irrigation water resource and energy consumption. Then, we conduct comparative studies of WFE Nexus between the urbanization and the un-urbanization area (basin) to provide a referential guide for optimal resource-policy nexus management. We expect to the proposed solutions can help achieve the main goals of the research, which is the promotion of human well-being and moving toward sustainable green economy and prosperous society.

    2017-12-01

    Analyses of the synergy and tradeoff of the water-energy-food nexus are keys to a sustainable society under the increasing demand for resources. Analyses of the water-energy-food nexus in Kumamoto, Japan showed that the paddy field for rice production, upstream of the basin with irrigated water from the river, had recharged the groundwater which is used as drinking water downstream in Kumamoto city without energy consumption for the transport of groundwater. National government regulations of "fallow rice fields" and urbanization after the 1970s caused the decrease in the groundwater recharge rate upstream in the paddy field area. This also lead to the decrease in water resources of groundwater downstream in Kumamoto city, which then required additional energy for water pumping. Therefore, the synergy of water-energy-food was lost after government regulations of rice production and urbanization which caused an impermeable layer for groundwater recharge. The nexus model has been established to analyze the synergy of water-energy-food, including cost-benefit analyses, food trade including rice with different scenarios of food self-sufficiency rates, water and energy consumption for food, and others. A decrease in rice consumption and production with the same self-sufficiency rate caused a decrease in water and energy consumption for rice production, and a decrease in carbon emissions. However, the cost of synergy loss in the water-energy-food nexus in Kumamoto did not outweigh the benefit of reductions in water and energy consumption for rice production.

    2015-10-01

    Full Text Available The water-energy-food nexus is promoted as a new approach for research and policy-making. But what does the nexus mean in practice and what kinds of benefits does it bring? In this article we share our experiences with using a nexus approach in Cambodia’s Tonle Sap Lake area. We conclude that water, energy and food security are very closely linked, both in the Tonle Sap and in the transboundary Mekong River Basin generally. The current drive for large-scale hydropower threatens water and food security at both local and national scales. Hence, the nexus provides a relevant starting point for promoting sustainable development in the Mekong. We also identify and discuss two parallel dimensions for the nexus, with one focusing on research and analysis and the other on integrated planning and cross-sectoral collaboration. In our study, the nexus approach was particularly useful in facilitating collaboration and stakeholder engagement. This was because the nexus approach clearly defines the main themes included in the process, and at the same time widens the discussion from mere water resource management into the broader aspects of water, energy and food security.

    Water resource and energy resource are intimately and highly interwoven, called ``water-energy nexus", which poses challenges for the sustainable management of water resource and energy resource. In this research, the Copula analysis method is first proposed to be applied in "water-energy nexus" field to clarify the internal relationship of water resource and energy resource, which is a favorable tool to explore the relevance among random variables. Beijing City, the capital of China, is chosen as a case study. The marginal distribution functions of water resource and energy resource are analyzed first. Then the Binary Copula function is employed to construct the joint distribution function of "water-energy nexus" to quantify the inherent relationship between water resource and energy resource. The results show that it is more appropriate to apply Lognormal distribution to establish the marginal distribution function of water resource. Meanwhile, Weibull distribution is more feasible to describe the marginal distribution function of energy resource. Furthermore, it is more suitable to adopt the Bivariate Normal Copula function to construct the joint distribution function of "water-energy nexus" in Beijing City. The findings can help to identify and quantify the "water-energy nexus". In addition, our findings can provide reasonable policy recommendations on the sustainable management of water resource and energy resource to promote regional coordinated development.

    2016-01-01

    This article presents a historical account of the close relationship between the coal mining industry and the federal and various state governments, thus over time building a state/coal industry nexus in Australia. It examines (1) an early colonial stage extending from the late 18th century to around the time of Federation in 1902 when the nexus emerged; (2) an intermediate stage from the early 20th century to the late 1970s when the nexus became solidified; and (3) a late stage from the early 1980s to the present day when the corporate sector came to dominate the nexus. Both Coalition and Australian Labor Party governments have consistently supported the exploitation of Australia's coal and natural gas, including recently coal seam gas, and supported the expansion of coal ports. An opposition movement has called for leaving coal and coal seam gas in the ground and shifting Australia’s energy production to renewable sources, particularly solar and wind energy. The article highlights how the nexus between coal mining and the state inhibits action on climate change. It argues this can be transcended by energy policy directed at socializing coal mining, wedded to a program of transitioning it to renewable energy production. - Highlights: • A close nexus exists between the coal industry and the state in Australia. • An anti-coal movement has developed in recent years in Australia. • Breaking the coal industry/state nexus requires socialization of energy production. • This would enable a shift from reliance on coal to renewable energy sources.

    Full Text Available Globally, natural resources are increasingly under pressure, especially due to population growth, economic growth and transformation as well as climate change. As a result, the water, energy, and food (WEF nexus approach has emerged to understand interdependencies and commonly manage resources within a multi-scale and multi-level framework. In Sub-Saharan Africa, the high and growing consumption of traditional biomass for cooking purposes - notably fuelwood and charcoal—is both a key source of energy and contributor for food security as well as a pressure on natural resources. Improving the bioenergy value chains is essential for limiting environmental degradation and for securing the livelihoods of millions of people. Although the WEF nexus approach entails large potential to address the complex problems arising along the bioenergy value chains, these are currently not considered. Based on the WEF nexus approach, we analyze the different steps within the charcoal value chain in Sub-Saharan Africa and highlight the respective interdependencies and the potential for improving overall socio-economic and environmental sustainability. We emphasize the water, energy and food related implications of vicious and virtuous production cycles, separated by value chain segments. We discuss the potential and major challenges for implementing more sustainable value chains. Furthermore, we underline the necessity of applying WEF nexus approaches to these value chains in order to optimize environmental and social outcomes.

  3. Securitising Sustainability? Questioning the 'Water, Energy and Food-Security Nexus'

    Directory of Open Access Journals (Sweden)

    Matthias Leese

    2015-02-01

    Full Text Available The water, energy and food-security nexus approach put forward by the Bonn2011 Conference highlights the need for an integrative approach towards issues of water, energy and food, and puts them under a general framework of security. While acknowledging the need for urgent solutions in terms of sustainability, the nexus approach, at the same time, makes a normative claim to tackle the needs of the poorest parts of the world population. A closer look at the underlying rationales and proposed policy instruments, however, suggests that the primary scope of the conference proceedings is not a normative one, but one that reframes the conflict between distributional justice and the needs of the world economy under the paradigm of security. Reading this slightly shifted perspective through a Foucauldian lens, we propose that security is now put forward as the key mechanism to foster a new 'green' economy, and that the needs of the poorest are, if anything at all, a secondary effect of the proposed nexus approach.

  4. The Rise and Implications of the Water-Energy-Food Nexus in Southeast Asia through an Environmental Justice Lens

    Carl Middleton

    2015-02-01

    Full Text Available This article maps the rise of the water-energy-food 'nexus' as a research, policy and project agenda in mainland Southeast Asia. We argue that introducing the concept of environmental justice into the nexus, especially where narratives, trade-offs and outcomes are contested, could make better use of how the nexus is framed, understood and acted upon. With funding from high-income country donors, it is found to have diffused from a global policy arena into a regional one that includes international and regional organisations, academic networks, and civil society, and national politicians and government officials. The nexus is yet to be extensively grounded, however, into national policies and practices, and broad-based local demand for nexus-framed policies is currently limited. The article contends that if the nexus is to support stated aspirations for sustainable development and poverty reduction, then it should engage more directly in identifying winners and losers in natural resource decision-making, the politics involved, and ultimately with the issue of justice. In order to do so, it links the nexus to the concept of environmental justice via boundary concepts, namely: sustainable development; the green economy; scarcity and addressing of trade-offs; and governance at, and across, the local, national and transnational scale.

    Full Text Available Objective: To examine whether company compliance with RS-17 influences the characterization of the casual nexus in physical therapists' expert reports of cumulative trauma disorders in the labor court of Pernambuco, Brazil. Method: The sample was composed of seven physical therapists who provided expert testimony regarding cumulative trauma disorder cases in the labor court of Pernambuco, Brazil. Data collection was performed across two stages. In the first stage, the experts answered a sociodemographic survey and requested the identification numbers of recent cases where expert testimony was provided to characterize the causal nexus. In the second stage, the researchers went to the labor court to collect expert testimony data. These experts indicated that of 75 total cases, 31% (N=23 of the companies fulfilled RS-17, whereas 69% (N=52 did not comply with the law. Results: Among the organizations that complied with legislation, 30% of the analyzed expert testimonies showed a positive causal nexus. However, of the companies that did not comply with RS-17, 71% of the expert testimonies revealed a causal nexus. These results indicate that the breach of the law increases the probability that a causal nexus will be determined by 54.8%. Conclusion: The results showed that failure to comply with RS-17 significantly increases the probability that a causal nexus will be determined in physical therapists' expert testimony of cumulative trauma disorders.

    Increasing population growth, consumption of natural resources, and deterioration of the environment coupled with climate change impacts (such as increased variability in precipitation) will challenge our abilities to provide water, energy and food (WEF) to the global populace. Less developed areas, such as the countries in Sub-Saharan Africa, are particularly vulnerable to such resource issues due to immature governance and management structures and strategies. We introduce an integrated approach to resource security analysis, which traditionally has focused on the WEF components separately and apply the methods to a suite of countries in Sub-Saharan Africa. Specifically, we evaluate the inter-connected nature of WEF securities by considering physical, demographic, socioeconomic, health, and institutional parameters related to each of the resource securities and by analyzing the relationships among the metrics. For example, reported food deficits for countries are strongly correlated with reported levels of access to safe drinking water. Multivariate statistical analyses are applied to identify relationships among resources and to develop indices that robustly and comprehensively capture the WEF nexus. Our results indicate that water plays the central role in the WEF nexus, due to its extensive use for both food and energy production in these countries. This approach provides a framework for analyzing the WEF nexus in other regions of the world.

  9. Nexus Thinking on Soil Carbon Dynamics and Soil Health

    Anthropocene is driven by global population of 7.5 billion in 2016, increasing annually by 80 million and projected to be 9.7 billion by 2050. The ecological impact (I=PAT, where P is population, A is affluence, and T is technology) of the population is similar to that of a geological force. Thus, humanity's impact is driven by demands for food, water, energy, and services derived from soil. Soil health, its capacity to function as a vital living system, is determined by quantity and quality of soil organic carbon (SOC) in the root zone ( 50cm). Maintenance of SOC at above the threshold level (1.5 to 2.0% by weight in the root zone) is critical to performing numerous ecosystem services for human wellbeing and nature conservancy. These services and functions strongly depend on nexus or inter-connectivity of biological processes within the pedosphere. The nexus is strongly governed by coupled biogeochemical cycling of water (H2O), carbon (C), nitrogen (N), phosphorus (P) and sulfur (S). Further, it is the nexus between pedological and biological processes that renews and purifies water by denaturing and filtering pollutants; circulates C among biotic and abiotic pools in close association with other elements (N, P, S); provides habitat and energy source for soil biota (macro, meso, and micro flora and fauna), facilitates exchanges of gases between soil and the atmosphere and moderates climate, and creates favorable rhizospheric processes that promote plant growth and enhance net primary productivity. Soil health, governed by SOC quality and quantity, determines the provisioning of numerous ecosystem services and the importance of nexus thinking is highlighted by the truism that "health of soil, plants, animals, human and ecosystem is one and indivisible." The sequestration of SOC depends on land use and soil management strategies which create a positive C budget. Thus, input of biomass-C into the soil must exceed the losses by erosion, mineralization and leaching

  10. Interpreting the dynamic nexus between energy consumption and economic growth: Empirical evidence from Russia

    International Nuclear Information System (INIS)

    2011-01-01

    Research on the nexus between energy consumption and economic growth is a fundamental topic for energy policy making and low-carbon economic development. Russia proves the third largest energy consumption country in the world in recent years, while little research has shed light upon its energy consumption issue till now, especially its energy-growth nexus. Therefore, this paper empirically investigates the dynamic nexus of the two variables in Russia based on the state space model. The results indicate that, first of all, Russia's energy consumption is cointegrated with its economic growth in a time-varying way though they do not have static or average cointegration relationship. Hence it is unsuitable to merely portrait the nexus in an average manner. Second, ever since the year of 2000, Russia's energy efficiency has achieved much more promotion compared with that in previous decades, mainly due to the industrial structure adjustment and technology progress. Third, among BRIC countries, the consistency of Russia's energy consumption and economic growth appears the worst, which suggests the complexity of energy-growth nexus in Russia. Finally, there exists bi-directional causality between Russia's energy consumption and economic growth, though their quantitative proportional relation does not have solid foundation according to the cointegration theory. - Research highlights: →This study investigates the dynamic nexus of energy consumption and economic growth in Russia. → Russia's energy consumption is cointegrated with its economic growth in a time-varying way though they do not have static or average cointegration relationship. → Ever since 2000, Russia's energy efficiency has achieved much more promotion compared with that in previous decades. → Among BRIC countries, the consistency of Russia's energy consumption and economic growth appears the worst. → There exists bi-directional causality between Russia's energy consumption and economic growth.

    public fears. Fourth, we must engage the public and make science more accessible to all. It is important that the scientific community, in its outreach, helps people, not only to see the fun of science, but also to understand what science is, what a scientific theory is - as opposed to belief, how science is done, that accepted scientific models or theories are based on evidence, the testing of hypotheses by experiment, and that theories change as new evidence emerges. What this really means is that the scientific community must understand that the nexus of science and public policy, inherently, means its nexus with public values. We must meet people where they live. Scientific perspectives will not prevail in all arenas, at all times, but we must engage, nonetheless. If we continue to invest in science and engineering research across a range of disciplines, develop human capital, engage on key public policy issues pro-actively and consistently, and engage the public in new, creative and respectful ways,we can heal rifts and address rising expectations worldwide. We can ensure our security by helping others to feel secure, and usher in a new 'golden age of scientific discovery'

    The energy-water nexus has been mapped for almost 12,000 watersheds distributed across the 21-economies comprising the Asia-Pacific Economic Cooperation. Water consumption for energy production was estimated for 9 different sectors including thermoelectric and hydroelectric power; energy extraction including coal, oil, natural gas, uranium and unconventional oil/gas; and, energy processing including oil and biofuels. Conversely, the energy consumed providing water services was mapped for three sectors, drinking water, waste water and seawater desalination. These measures of resource use were put in context by drawing comparison with published measures of water risk. The objective of the mapping was to quantify the energy-water nexus and its variability at the subnational level, pinpoint potential vulnerabilities, and identify opportunities for international collaboration.

    Numerous challenges coalesce to make Southern Africa emblematic of the connections between climate and the water-energy-food nexus. Rainfall and river flows in the region show high levels of variability across a range of spatial and temporal scales. Physical and socioeconomic exposure to climate variability and change is high, for example, the contribution of electricity produced from hydroelectric sources is over 30% in Madagascar and Zimbabwe and almost 100% in the DRC, Lesotho, Malawi, and Zambia. The region's economy is closely linked with that of the rest of the African continent and climate-sensitive food products are an important item of trade. Southern Africa's population is concentrated in regions exposed to high levels of hydro-meteorological variability, and will increase rapidly over the next four decades. The capacity to manage the effects of climate variability tends, however, to be low. Moreover, with climate change annual precipitation levels, soil moisture and runoff are likely to decrease and rising temperatures will increase evaporative demand. Despite high levels of hydro-meteorological variability, the sectoral and cross-sectoral water-energy-food linkages with climate in Southern Africa have not been considered in detail. Lack of data and questionable reliability are compounded by complex dynamic relationships. We review the role of climate in Southern Africa's nexus, complemented by empirical analysis of national level data on climate, water resources, crop and energy production, and economic activity. Our aim is to examine the role of climate variability as a driver of production fluctuations in the nexus, and to improve understanding of the magnitude and temporal dimensions of their interactions. We first consider national level exposure of food, water and energy production to climate in aggregate economic terms and then examine the linkages between interannual and multi-year climate variability and economic activity, focusing on food and

    The water, energy, and food (WEF) nexus is an emerging issue in the concern of fulfilling the human requirements with a lack of available resources. The WEF nexus concept arises to develop a sustainable resources planning and management. In the concept, the three valuable resources (i.e. water, energy, and food) are inevitably interconnected thus it becomes a challenge for researchers to understand the complicated interdependency. A few studies have been committed for interpreting and implementing the WEF nexus using a computer based simulation model. Some of them mentioned that a trade-off is one alternative solution that can be taken to secure the available resources. Taking a concept of inter-basin water transfer, this study attempts to introduce an idea to develop a WEF nexus model for inter-basin resources trading simulation. Using the trading option among regions (e.g., cities, basins, or even countries), the model provides an opportunity to increase overall resources availability without draining local resources. The proposed model adopted the calculation process of an amount of water, energy, and food from a nation-wide model, with additional input and analysis process to simulate the resources trading between regions. The proposed model is applied for a hypothetic test area in South Korea for demonstration purposes. It is anticipated that the developed model can be a decision tool for efficient resources allocation for sustainable resources management.

    Emerging interdisciplinary science efforts are providing new understanding of the interdependence of food, energy, and water (FEW) systems. These science advances, in turn, provide critical information for coordinated management to improve the affordability, reliability, and environmental sustainability of FEW systems. Here we describe the current state of the FEW nexus and approaches to managing resource conflicts through reducing demand and increasing supplies, storage, and transport. Despite significant advances within the past decade, there are still many challenges for the scientific community. Key challenges are the need for interdisciplinary science related to the FEW nexus; ground-based monitoring and modeling at local-to-regional scales; incorporating human and institutional behavior in models; partnerships among universities, industry, and government to develop policy relevant data; and systems modeling to evaluate trade-offs associated with FEW decisions.

    Full Text Available Introduction: The National Emergency X-radiography Utilization Study (NEXUS criteria are used extensively in emergency departments to rule out C-spine injuries (CSI in the general population. Although the NEXUS validation set included 2,943 elderly patients, multiple case reports and the Canadian C-Spine Rules question the validity of applying NEXUS to geriatric populations. The objective of this study was to validate a modified NEXUS criteria in a low-risk elderly fall population with two changes: a modified definition for distracting injury and the definition of normal mentation. Methods: This is a prospective, observational cohort study of geriatric fall patients who presented to a Level I trauma center and were not triaged to the trauma bay. Providers enrolled non-intoxicated patients at baseline mental status with no lateralizing neurologic deficits. They recorded midline neck tenderness, signs of trauma, and presence of other distracting injury. Results: We enrolled 800 patients. One patient fall event was excluded due to duplicate enrollment, and four were lost to follow up, leaving 795 for analysis. Average age was 83.6 (range 65-101. The numbers in parenthesis after the negative predictive value represent confidence interval. There were 11 (1.4% cervical spine injuries. One hundred seventeen patients had midline tenderness and seven of these had CSI; 366 patients had signs of trauma to the face/neck, and 10 of these patients had CSI. Using signs of trauma to the head/neck as the only distracting injury and baseline mental status as normal alertness, the modified NEXUS criteria was 100% sensitive (CI [67.9-100] with a negative predictive value of 100 (98.7-100. Conclusion: Our study suggests that a modified NEXUS criteria can be safely applied to low-risk elderly falls.

    2017-01-01

    Highlights: • The issues to energy conversion stemming from the water-energy nexus are investigated. • The objective is to minimize power curtailments caused by critical river water conditions. • A water-energy nexus model for smart management of water resources is developed. • Systemic risks to energy conversion stem from critical temperature and flow regimes. • Full coordination of the hydrologically-linked units provides the most effective strategy. - Abstract: The water-energy nexus refers to the water used to generate electricity and to the electric energy used to collect, clean, move, store, and dispose of water. Water is used in all stages of electric energy conversion making power systems vulnerable to water scarcity and warming. In particular, a water flow decrease and temperature increase in rivers can significantly limit the generation of electricity. This paper investigates the issues to energy conversion stemming from the water-energy nexus and mitigates them by developing a model for the smart utilization of water resources. The objective is to minimize power curtailments caused by a river water flow decrease and a temperature increase. The developed water-energy nexus model integrates the operational characteristics of hydro power plants, the environmental conditions, the river water temperature prediction and thermal load release in river bodies. The application to a hydraulic cascade of hydro and a thermal power plants under drought conditions shows that smart water management entails a significant reduction of power curtailments. In general, the full coordination of the power outputs of the units affected by the hydrological link provides the most effective mitigations of the potential issues stemming from the water-energy nexus. Finally, critical temperature and flow regimes are identified which severely impact the energy conversion and may cause systemic risks in case the generators in one region must be simultaneously curtailed.

    This book explores the nexus among food, energy and water in peri-urban areas, demonstrating how relevant this nexus is for environmental sustainability. In particular it examines the effective management of the nexus in the face of the risks and trade-offs of mitigation policies, and as a mean to create resilience to climate change. The book delineates strategies and actions necessary to develop and protect our natural resources and improve the functionality of the nexus, such as: integrated management of the major resources that characterize the metabolism of a city, stronger coordination among stakeholders who often weight differently the services that are relevant to their individual concerns, integration of efforts towards environmental protection, adaptation to and prevention of climate change and disaster risks mitigation.

    2017-12-01

    Rapid urbanization, population growth and related structural changes with-in the economy of a developing country act as a stressor on energy and water demand, which forms a well-established energy-water nexus. Energy-water nexus is thoroughly studied at various spatial scales viz. city level, river basin level and national level- to guide different stakeholders for sustainable management of energy and water. However, temporal dimensions of energy-water nexus at national level have not been thoroughly investigated because of unavailability of relevant time-series data. In this study we investigated energy-water nexus at national level using environmentally-extended input-output tables for Indian economy (2004-2013) as provided by EORA database. Perturbation based sensitivity analysis is proposed to highlight the critical nodes of interactions among economic sectors which is further linked to detect the synergistic effects of energy and water consumption. Technology changes (interpreted as change in value of nodes) results in modification of interactions among economic sectors and synergy is affected through direct as well as indirect effects. Indirect effects are not easily understood through preliminary examination of data, hence sensitivity analysis within an input-output framework is important to understand the indirect effects. Furthermore, time series data helps in developing the understanding on dynamics of synergistic effects. We identified the key sectors and technology changes for Indian economy which will provide the better decision support for policy makers about sustainable use of energy-water resources in India.

  7. Co-exploring the Water-Energy-Food Nexus: Facilitating Dialogue through Participatory Scenario Building

    2017-05-01

    Full Text Available The “water-energy-food nexus” has become an increasingly popular way to frame the challenges associated with reconciling human development objectives with responsible management of natural resources and ecosystems. Yet the nexus is complex, requiring effective engagement between expert and Non-expert stakeholders in order to understand biophysical inter-linkages between resources and resource flows and social interactions between different actors in the socio-ecological system and landscape. This can be a substantial challenge due to varying levels of knowledge and understanding amongst actors with divergent, and often entrenched, interests. This paper presents insights on how participatory scenario-building processes can create space for dialogue amongst stakeholders with differing knowledge, experience, priorities, and political perspectives. Drawing on completed and on-going research applying a “nexus toolkit” in Ethiopia and Rwanda respectively, we contribute to a generalized conceptual framework for addressing, communicating, and assessing the water-energy-food nexus, with a particular focus on how to utilize the nexus concept in practice. This framework has significant potential to help better understand interactions at landscape level, for example, between charcoal production, food production, and environmental systems. We find that participatory scenario-building processes that facilitate engagement beyond technical aspects to include social, economic and political concerns provide a valuable space for discussing and negotiating development pathways that are sustainable both biophysically and socio-economically. In addition, the involvement of stakeholders throughout the project process greatly enhances the quality and legitimacy of results. Furthermore, we suggest that by building capacity amongst stakeholders to maintain a quantitative “nexus toolkit,” it has a better chance of informing decision-making and for supporting

    Full Text Available Nel Glass, K Robyn OgleSchool of Nursing, Midwifery and Paramedicine, Australian Catholic University, Fitzroy, VIC, AustraliaBackground: The paper reports on the importance of the interpersonal nexus within qualitative research processes, from a recent research project on patient experiences of shoulder surgery. Our aim is to reveal the importance of qualitative research processes and specifically the role of the interpersonal nexus in generating quality data. Literature related to the importance of human interactions and interpersonal communication processes in health-related research remains limited. Shoulder surgery has been reported to be associated with significant postoperative pain. While shoulder surgery research has investigated various analgesic techniques to determine key efficacy and minimization of adverse side effects, little has been reported from the patient perspective.Methods: Following institutional ethics approval, this project was conducted in two private hospitals in Victoria, Australia, in 2010. The methods included a survey questionnaire, semistructured interviews, and researcher-reflective journaling. Researcher-reflective journaling was utilized to highlight and discuss the interpersonal nexus.Results: This research specifically addresses the importance of the contributions of qualitative methods and processes to understanding patient experiences of analgesic efficacy and shoulder surgery. The results reveal the importance of the established research process and the interwoven interpersonal nexus between the researcher and the research participants. The interpersonal skills of presencing and empathetic engagement are particularly highlighted.Conclusion: The authors attest the significance of establishing an interpersonal nexus in order to reveal patient experiences of shoulder surgery. Interpersonal emotional engagement is particularly highlighted in data collection, in what may be otherwise understated and overlooked

  9. Quantitative Story Telling: Initial steps towards bridging perspectives and tools for a robust nexus assessment

    Cabello, Violeta

    2017-04-01

    This communication will present the advancement of an innovative analytical framework for the analysis of Water-Energy-Food-Climate Nexus termed Quantitative Story Telling (QST). The methodology is currently under development within the H2020 project MAGIC - Moving Towards Adaptive Governance in Complexity: Informing Nexus Security (www.magic-nexus.eu). The key innovation of QST is that it bridges qualitative and quantitative analytical tools into an iterative research process in which each step is built and validated in interaction with stakeholders. The qualitative analysis focusses on the identification of the narratives behind the development of relevant WEFC-Nexus policies and innovations. The quantitative engine is the Multi-Scale Analysis of Societal and Ecosystem Metabolism (MuSIASEM), a resource accounting toolkit capable of integrating multiple analytical dimensions at different scales through relational analysis. Although QST may not be labelled a data-driven but a story-driven approach, I will argue that improving models per se may not lead to an improved understanding of WEF-Nexus problems unless we are capable of generating more robust narratives to frame them. The communication will cover an introduction to MAGIC project, the basic concepts of QST and a case study focussed on agricultural production in a semi-arid region in Southern Spain. Data requirements for this case study and the limitations to find, access or estimate them will be presented alongside a reflection on the relation between analytical scales and data availability.

    As demand for energy grows, the energy sector is experiencing increasing competition for water. With increasing population and changing environmental, socioeconomic scenarios, new technology and investment decisions must be made for optimized and sustainable energy-water resource management. This requires novel scientific insights into the complex interdependencies of energy-water infrastructures across multiple space and time scales. An integrated data driven modeling, analysis, and visualization capability is needed to understand, design, and develop efficient local and regional practices for the energy-water infrastructure components that can be guided with strategic (federal) policy decisions to ensure national energy resilience. To meet this need of the energy-water nexus (EWN) community, an Energy-Water Knowledge Discovery Framework (EWN-KDF) is being proposed to accomplish two objectives: Development of a robust data management and geovisual analytics platform that provides access to disparate and distributed physiographic, critical infrastructure, and socioeconomic data, along with emergent ad-hoc sensor data to provide a powerful toolkit of analysis algorithms and compute resources to empower user-guided data analysis and inquiries; and Demonstration of knowledge generation with selected illustrative use cases for the implications of climate variability for coupled land-water-energy systems through the application of state-of-the art data integration, analysis, and synthesis. Oak Ridge National Laboratory (ORNL), in partnership with Argonne National Laboratory (ANL) and researchers affiliated with the Center for International Earth Science Information Partnership (CIESIN) at Columbia University and State University of New York-Buffalo (SUNY), propose to develop this Energy-Water Knowledge Discovery Framework to generate new, critical insights regarding the complex dynamics of the EWN and its interactions with climate variability and change.

    Full Text Available To date, the treatment of immune-mediated kidney diseases has only marginally benefited from highly specific biological drugs that have demonstrated remarkable effects in many other diseases. What accounts for this disparity? In April 2016, the International Society of Nephrology held a Nexus meeting on Translational Immunology in Nephrology in Berlin, Germany, to identify and discuss hurdles that block the translational flow of target identification, and preclinical and clinical target validation in the domain of immune-mediated kidney disease. A broad panel of experts including basic scientists, translational researchers, clinical trialists, pharmaceutical industry drug developers, and representatives of the American and European regulatory authorities made recommendations on how to overcome such hurdles at all levels of the translational research process. The results of these discussions are presented here, which may serve as a roadmap for how to optimize the process of developing more innovative and effective drugs for patients with immune-mediated kidney diseases.

  12. Multi-Stakeholder Development of a Serious Game to Explore the Water-Energy-Food-Land-Climate Nexus: The SIM4NEXUS Approach

    Directory of Open Access Journals (Sweden)

    Janez Sušnik

    2018-02-01

    Full Text Available Water, energy, food, land and climate form a tightly-connected nexus in which actions on one sector impact other sectors, creating feedbacks and unanticipated consequences. This is especially because at present, much scientific research and many policies are constrained to single discipline/sector silos that are often not interacting (e.g., water-related research/policy. However, experimenting with the interaction and determining how a change in one sector could impact another may require unreasonable time frames, be very difficult in practice and may be potentially dangerous, triggering any one of a number of unanticipated side-effects. Current modelling often neglects knowledge from practice. Therefore, a safe environment is required to test the potential cross-sectoral implications of policy decisions in one sector on other sectors. Serious games offer such an environment by creating realistic ‘simulations’, where long-term impacts of policies may be tested and rated. This paper describes how the ongoing (2016–2020 Horizon2020 project SIM4NEXUS will develop serious games investigating potential plausible cross-nexus implications and synergies due to policy interventions for 12 multi-scale case studies ranging from regional to global. What sets these games apart is that stakeholders and partners are involved in all aspects of the modelling definition and process, from case study conceptualisation, quantitative model development including the implementation and validation of each serious game. Learning from playing a serious game is justified by adopting a proof-of-concept for a specific regional case study in Sardinia (Italy. The value of multi-stakeholder involvement is demonstrated, and critical lessons learned for serious game development in general are presented.

    Directory of Open Access Journals (Sweden)

    Anna Mdee

    2017-02-01

    Full Text Available This article considers the dilemma of managing competing uses of surface water in ways that respond to social, ecological and economic needs. Current approaches to managing competing water use, such as Integrated Water Resources Management (IWRM and the concept of the water-energy-food nexus do not adequately disaggregate the political nature of water allocations. This is analysed using Mehta’s (2014 framework on orders of scarcity to disaggregate narratives of water scarcity in two ethnographic case studies in the WamiRuvu River Basin in Tanzania: one of a mountain river that provides water to urban Morogoro, and another of a large donor-supported irrigation scheme on the Wami River. These case studies allow us to explore different interfaces in the food-water-energy nexus. The article makes two points: that disaggregating water scarcity is essential for analysing the nexus; and that current institutional frameworks (such as IWRM mask the political nature of the nexus, and therefore do not provide an adequate platform for adjudicating the interfaces of competing water use.

    2015-04-01

    The utilisation of Energy, Water and Food (EWF) resources can be described as a nexus of complex linkages embodied in industrial and natural processes. Food production is one such example of a system that mobilises EWF resources to deliver a product which is highly influenced by the efficiency of the industrial processes contributing to it and the conditions of the surrounding natural environment. Aggregating the utilisation of EWF resources into interconnected sub-systems is necessary for the accurate representation of the system's dynamics in terms of its material flow and resource consumption. The methodology used in this study is an extension of previous work developed regarding nexus analysis (Al-Ansari et al. 2014a, Al-Ansari et al. 2014b). Life cycle assessment (LCA) is used to prepare detailed models of the sub-system components, determine the linkages between the different nexus constituents and evaluate impacts on the natural environment. The nexus system is comprised of water sub-systems represented by a reverse osmosis (RO) desalination process. Energy sub-systems for power generation include models for a combined cycle gas turbine (CCGT) and solar Photovoltaics (PV) energy generation, as well as an amine based CO2 capture process enabling the utilisation of CO2 for the artificial fertilization of crops. The agricultural sub-systems include the production and application of fertilizers and the raising of livestock. A biomass integrated gasification combined cycle (BIGCC) for power generation using waste manure from the livestock sub-system is also included. The objective of this study is to consider a conventional food system in Qatar and enhance its environmental performance by using a nexus approach to examine different scenarios and operating modes. For the Qatar case study, three scenarios and four modes of operation were developed as part of the analysis. The baseline scenario uses fossil fuel to power the entire EWF nexus system using CCGT, the

    Highlights: •This study quantifies the nexus as energy intensity and greenhouse gas potential. •Baseline water stress and return flow ratio are identified as water risks. •Source water accessibility significantly contributes to variations in the nexus. •Water risks have little impact on the nexus of wastewater systems. •Study on the nexus is suggested to be conducted at regional levels. -- Abstract: The importance of the interdependence between water and energy, also known as the water-energy nexus, is well recognized. The water-energy nexus is typically characterized in resource use efficiency terms such as energy intensity. This study aims to explore the quantitative results of the nexus in terms of energy intensity and environmental impacts (mainly greenhouse gas emissions) on existing water systems within urban water cycles. We also characterized the influence of water risks on the water-energy nexus, including baseline water stress (a water quantity indicator) and return flow ratio (a water quality indicator). For the 20 regions and 4 countries surveyed (including regions with low to extremely high water risks that are geographically located in Africa, Australia, Asia, Europe, and North America), their energy intensities were positively related to the water risks. Regions with higher water risks were observed to have relatively higher energy and GHG intensities associated with their water supply systems. This mainly reflected the major influence of source water accessibility on the nexus, particularly for regions requiring energy-intensive imported or groundwater supplies, or desalination. Regions that use tertiary treatment (for water reclamation or environmental protection) for their wastewater treatment systems also had relatively higher energy and GHG emission intensities, but the intensities seemed to be independent from the water risks. On-site energy recovery (e.g., biogas or waste heat) in the wastewater treatment systems offered a great

    Purves, L. R.

    1994-01-01

    NEXUS, the NASA Engineering Extendible Unified Software system, is a research set of computer programs designed to support the full sequence of activities encountered in NASA engineering projects. This sequence spans preliminary design, design analysis, detailed design, manufacturing, assembly, and testing. NEXUS primarily addresses the process of prototype engineering, the task of getting a single or small number of copies of a product to work. Prototype engineering is a critical element of large scale industrial production. The time and cost needed to introduce a new product are heavily dependent on two factors: 1) how efficiently required product prototypes can be developed, and 2) how efficiently required production facilities, also a prototype engineering development, can be completed. NEXUS extendibility and unification are achieved by organizing the system as an arbitrarily large set of computer programs accessed in a common manner through a standard user interface. The NEXUS interface is a multipurpose interactive graphics interface called NASCAD (NASA Computer Aided Design). NASCAD can be used to build and display two and three-dimensional geometries, to annotate models with dimension lines, text strings, etc., and to store and retrieve design related information such as names, masses, and power requirements of components used in the design. From the user's standpoint, NASCAD allows the construction, viewing, modification, and other processing of data structures that represent the design. Four basic types of data structures are supported by NASCAD: 1) three-dimensional geometric models of the object being designed, 2) alphanumeric arrays to hold data ranging from numeric scalars to multidimensional arrays of numbers or characters, 3) tabular data sets that provide a relational data base capability, and 4) procedure definitions to combine groups of system commands or other user procedures to create more powerful functions. NASCAD has extensive abilities to

    2016-01-01

    The management of simulation workflows represents a significant task for the individual computational researcher. Automation of the required tasks involved in simulation work can decrease the overall time to solution and reduce sources of human error. A new simulation workflow management system, Nexus, is presented to address these issues. Nexus is capable of automated job management on workstations and resources at several major supercomputing centers. Its modular design allows many quantum simulation codes to be supported within the same framework. Current support includes quantum Monte Carlo calculations with QMCPACK, density functional theory calculations with Quantum Espresso or VASP, and quantum chemical calculations with GAMESS. Users can compose workflows through a transparent, text-based interface, resembling the input file of a typical simulation code. A usage example is provided to illustrate the process.

    Energy and water are interlinked. The development, use, and waste generated by demand for both resources drive global change. Managing them in tandem offers potential for global-change adaptation but presents institutional challenges. This paper advances understanding of the water-energy nexus by demonstrating how these resources are coupled at multiple scales, and by uncovering institutional opportunities and impediments to joint decision-making. Three water-energy nexus cases in the United States are examined: (1) water and energy development in the water-scarce Southwest; (2) conflicts between coal development, environmental quality, and social impacts in the East; and (3) tensions between environmental quality and economic development of shale natural gas in the Northeast and Central U.S. These cases are related to Eastern, Central, and Western regional stakeholder priorities collected in a national effort to assess energy-water scenarios. We find that localized challenges are diminished when considered from broader perspectives, while regionally important challenges are not prioritized locally. The transportability of electricity, and to some extent raw coal and gas, makes energy more suitable than water to regionalized global-change adaptation, because many of the impacts to water availability and quality remain localized. We conclude by highlighting the need for improved coordination between water and energy policy. - Highlights: >Water-energy nexus construct considers institutions not just resource inputs. > Energy policy offers more scope for global-change adaptation than does water policy. > U.S. scenarios highlight water impacts and policy choices of energy development. > Water-energy policy tradeoffs may be mitigated across scales of resource use.

    Energy and water are interlinked. The development, use, and waste generated by demand for both resources drive global change. Managing them in tandem offers potential for global-change adaptation but presents institutional challenges.

    2016-03-01

    Renewed effort to understand the social-ecological context of health is drawing attention to the dynamics of land and water resources and their combined influence on the determinants of health. A new area of research, education and policy is emerging that focuses on the land-water-health nexus: this orientation is applicable from small wetlands through to large-scale watersheds or river basins, and draws attention to the benefits of combined land and water governance, as well as the interrelated implications for health, ecological and societal concerns. Informed by research precedents, imperatives and collaborations emerging in Canada and parts of Oceania, this review profiles three integrative, applied approaches that are bringing attention to the importance the land-water-health nexus within the Pacific Basin: wetlands and watersheds as intersectoral settings to address land-water-health dynamics; tools to integrate health, ecological and societal dynamics at the land-water-health nexus; and indigenous leadership that is linking health and well-being with land and water governance. Emphasis is given to key characteristics of a new generation of inquiry and action at the land-water-health nexus, as well as capacity-building, practice and policy opportunities to address converging environmental, social and health objectives linked to the management and governance of land and water resources.

    Full Text Available While the water–energy–food nexus approach is becoming increasingly important for more efficient resource utilization and economic development, limited quantitative tools are available to incorporate the approach in decision-making. We propose a spatially explicit framework that couples two well-established water and power system models to develop a decision support tool combining multiple nexus objectives in a linear objective function. To demonstrate our framework, we compare eight Nepalese power development scenarios based on five nexus objectives: minimization of power deficit, maintenance of water availability for irrigation to support food self-sufficiency, reduction in flood risk, maintenance of environmental flows, and maximization of power export. The deterministic multi-objective optimization model is spatially resolved to enable realistic representation of the nexus linkages and accounts for power transmission constraints using an optimal power flow approach. Basin inflows, hydropower plant specifications, reservoir characteristics, reservoir rules, irrigation water demand, environmental flow requirements, power demand, and transmission line properties are provided as model inputs. The trade-offs and synergies among these objectives were visualized for each scenario under multiple environmental flow and power demand requirements. Spatially disaggregated model outputs allowed for the comparison of scenarios not only based on fulfillment of nexus objectives but also scenario compatibility with existing infrastructure, supporting the identification of projects that enhance overall system efficiency. Though the model is applied to the Nepalese nexus from a power development perspective here, it can be extended and adapted for other problems.

    Full Text Available There is a strong relationship between organised crime and civil war. This article contributes to the crime-conflict nexus literature by providing a consideration of the role of organised crime in the Syrian conflict. It provides an overview of pre- and post-war organised crime in Syria. The article then builds the argument that war provides opportunities for organised crime through the state’s diminished law enforcement ability; the economic hardship which civilians face during war; and the abundance of armed groups who all need to generate revenue. Secondly, the paper argues that organised crime also affects the intensity and duration of war by enabling militants to reproduce themselves materially and to build institutions amongst the communities where they are active. The relationships between armed groups and local populations emerge as a central theme in understanding the crime-conflict nexus.

    2017-12-01

    Future Earth launched its W-E-F Nexus project in 2015. The focus of the project was to explore how improved governance and integrated information systems could support sustainability in the W-E-F Nexus. Workshops were held in four regions of the world (North America, Europe, Eastern Asia, and Southern Africa) which facilitated a better understanding of the current role of information in decision-making within the W-E-F Nexus. In each of these workshops, needs and options for improving the provision of relevant integrated data and information to support decision-making were discussed. The workshops provided distinct perspectives on W-E-F issues for each region and each sector. Regional differences arise from climate, geomorphology, natural resources and existing infrastructure as well as the economic and social policies within each country. While the needs associated with this diversity are large, it is still possible to identify unifying themes and requirements for data and information which appeared very similar in all the regions. Important themes involve developing a common rigorous definition of the Nexus, ensuring the availability of data of all types are available in the scales, frequencies, and accuracies needed to support better decision making; and promoting the gathering, analysis and use of information to break down the silos associated with the three sectors are made. Information is also needed to monitor the effects of land ownership and land management on W-E-F issues, to maximize the efficiencies that can be realized from joint planning and increased coherence in the sectoral policy approaches to address climate and environmental issues. After commenting on these opportunities the presentation will outline possible elements of a research agenda for moving the W-E-F Nexus approach forward.

    Full Text Available Clinicians, afraid of missing intracranial injuries, liberally obtain computed tomographic (CT head imaging in blunt trauma patients. Prior work suggests that clinical criteria (National Emergency X-Radiography Utilization Study [NEXUS] Head CT decision instrument [DI] can reliably identify patients with important injuries, while excluding injury, and the need for imaging in many patients. Validating this DI requires confirmation of the hypothesis that the lower 95% confidence limit for its sensitivity in detecting serious injury exceeds 99.0%. A secondary goal of the study was to complete an independent validation and comparison of the Canadian and NEXUS Head CT rules among the subgroup of patients meeting the inclusion and exclusion criteria.We conducted a prospective observational study of the NEXUS Head CT DI in 4 hospital emergency departments between April 2006 and December 2015. Implementation of the rule requires that patients satisfy 8 criteria to achieve "low-risk" classification. Patients are excluded from "low-risk" classification and assigned "high-risk" status if they fail to meet 1 or more criteria. We examined the instrument's performance in assigning "high-risk" status to patients requiring neurosurgical intervention among a cohort of 11,770 blunt head injury patients. The NEXUS Head CT DI assigned high-risk status to 420 of 420 patients requiring neurosurgical intervention (sensitivity, 100.0% [95% confidence interval [CI]: 99.1%-100.0%]. The instrument assigned low-risk status to 2,823 of 11,350 patients who did not require neurosurgical intervention (specificity, 24.9% [95% CI: 24.1%-25.7%]. None of the 2,823 low-risk patients required neurosurgical intervention (negative predictive value [NPV], 100.0% [95% CI: 99.9%-100.0%]. The DI assigned high-risk status to 759 of 767 patients with significant intracranial injuries (sensitivity, 99.0% [95% CI: 98.0%-99.6%]. The instrument assigned low-risk status to 2,815 of 11

    Extracting, delivering, and disposing water requires energy, and similarly, many processes for extracting and refining various fuel sources and producing electricity use water. This so-called 'water-energy nexus', is important to understand due to increasing energy demands and decreasing freshwater supplies in many areas. This paper performs a country-level quantitative assessment of this nexus in the MENA region. The results show a highly skewed coupling with a relatively weak dependence of energy systems on fresh water, but a strong dependence of water abstraction and production systems on energy. In case of Saudi Arabia it is estimated that up to 9% of the total annual electrical energy consumption may be attributed to ground water pumping and desalination. Other countries in the Arabian Gulf may be consuming 5-12% or more of total electricity consumption for desalination. The results suggest that policy makers should explicitly consider energy implications in water intensive food imports and future restructuring of water demand. This will help in making more integrated decisions on water and energy infrastructure systems. An integrated assessment may in some cases favor water reuse and changes in the agricultural sector as opposed to the expansion of energy intensive and financially expensive desalination systems. - Highlights: > The water-energy nexus in MENA has a highly skewed coupling. > Energy production systems are weakly dependent on fresh water. > Water abstraction and production is strongly dependent on energy. > In Arabian Gulf countries, 5-12% or more of total electricity consumption is for desalination. > Energy implications in water intensive food imports should be included in policy considerations.

  12. Connecting cities and their environments: Harnessing the water-energy-food nexus for sustainable urban development

    Directory of Open Access Journals (Sweden)

    Chan Arthur

    2015-01-01

    Full Text Available Thousands of years of development have made the production and consumption of water, energy, and food for urban environments more complex. While the rise of cities has fostered social and economic progress, the accompanying environmental pressures threaten to undermine these benefits. The compounding effects of climate change, habitat loss, pollution, overexploitation (in addition to financial constraints make the individual management of these three vital resources incompatible with rapidly growing populations and resource-intensive lifestyles. Nexus thinking is a critical tool to capture opportunities for urban sustainability in both industrialised and developing cities. A nexus approach to water, energy, and food security recognises that conventional decisionmaking, strictly confined within distinct sectors, limits the sustainability of urban development. Important nexus considerations include the need to collaborate with a wide spectrum of stakeholders, and to “re-integrate” urban systems. This means recognising the opportunities coming from the interconnected nature of cities and metropolitan regions, including links with rural environments and wider biophysical dynamics.

  13. The Potential Benefits of Earth Observations for the Water-Energy-Food Nexus and Beyond

    Lawford, R. G.

    2016-12-01

    Earth Observations have been shown to have the potential to play an important role in the management of the Water-Energy-Food (W-E-F) Nexus. To date, their primary application has come through support to decisions related to the better use of water in the production of food and in the extraction of energy. However, to be fully effective, the uses of Earth observations should be coordinated across the sectors and appropriately applied at multiple levels of the governance process. This observation argues for a new approach to governance and management of the W-E-F Nexus that implements collaborative planning based on broader usage of Earth observations. The Future Earth W-E-F Nexus Cluster project has documented a number of ways in which Earth observations can support decision-making that benefits the management of these sectors and has identified gaps in the data and information systems needed for this purpose. This presentation will summarize those findings and discuss how the role of Earth observations could be strengthened and expanded to the Sustainable Development Goals and Integrated Water Resources Management.

    New hydrological insights for the region: Besides the innovative methodology, this research adds to the underserved local perspective in the WEF-Nexus research. The survey shows different livelihood profiles for the two groups and a lack of direct social links between them in the WEF-Nexus context. Also indirect links through consumption of the other group’s food products could not be identified. However, a large fraction of the population share the use of char coal for cooking, the Makiling groundwater for drinking and various household purposes and the Central Market in Los Banos for their food supply.

    Throughout the world, much food produced is wasted. The resource impact of producing wasted food is substantial; however, little is known about the energy and water consumed in managing food waste after it has been disposed. Herein, we characterize food waste within the Food-Energy-Water (FEW) nexus and parse the differential FEW effects of producing uneaten food and managing food loss and waste. We find that various food waste management options, such as waste prevention, landfilling, composting, anaerobic digestion, and incineration, present variable pathways for FEW impacts and opportunities. Furthermore, comprehensive sustainable management of food waste will involve varied mechanisms and actors at multiple levels of governance and at the level of individual consumers. To address the complex food waste problem, we therefore propose a "food-waste-systems" approach to optimize resources within the FEW nexus. Such a framework may be applied to devise strategies that, for instance, minimize the amount of edible food that is wasted, foster efficient use of energy and water in the food production process, and simultaneously reduce pollution externalities and create opportunities from recycled energy and nutrients. Characterization of FEW nexus impacts of wasted food, including descriptions of dynamic feedback behaviors, presents a significant research gap and a priority for future work. Large-scale decision making requires more complete understanding of food waste and its management within the FEW nexus, particularly regarding post-disposal impacts related to water.

  18. Literacy in the 21st century: Towards a dynamic nexus of social relations

    2015-06-01

    Literacy is an essential means of communication. It enables individuals, communities and institutions to interact, over time and across space, as they develop a web of social relations via language. Effective literacy policies, programmes and practices expand the scale of social communication and interaction. Thus, literacy thrives when a state of connectedness - or social nexus of relations - is forged and sustained among individuals, households, communities and social institutions. This paper provides an overview of recent literacy trends and challenges as well as core aspects of the policy strategies which seek to address them. It reviews the main barriers or complicating factors which limit the effective implementation of literacy policies. The paper describes how the notion of non-formal education, which frames many scholarly and policy accounts of adult literacy work today, is under-conceptualised. One result of this is a relatively undifferentiated view of literacy programmes and their specific non-formal components. The author argues that the concept of the social nexus of literacy is implicit in many analyses of literacy policies and strategies. Thus, well-defined, context-specific and sharply conceived literacy policies, which enhance the social nexus of literacy, are crucial for improving the effectiveness of literacy work.

    Energy shortages and resources constraints have both emerged as one of the greatest challenges facing mankind this century.By 2030, humans will require 30% more water, 45% more energy and 50 % more food. The Food- Energy -Water (FEW) nexus is extensive and few areas are now untouched by it. Competition for energy and resources is increasing , especially in urban areas. To explore ways of meeting the challenges and seizing new opportunities, indicators could provide valuable information on complex issues in a relatively accessible way. In this paper, we develop a framework for selection of indicators, to assess the comprehensive sustainable status and trends to the FEW system .We identify indicators based on related ecosystem services to examine the status of FEW sustainability. We test the framework on two case studies in Taipei and Canberra. Several criteria were used to evaluate the usefulness of the selected indicators, including scalability and sensitivity . This paper identifies the need to establish indicators that entirely and largely reveal the potential of an ecosystem services support by FEW sustainability.

    The Drosophila Genome Nexus is a population genomic resource that provides D. melanogaster genomes from multiple sources. To facilitate comparisons across data sets, genomes are aligned using a common reference alignment pipeline which involves two rounds of mapping. Regions of residual heterozygosity, identity-by-descent, and recent population admixture are annotated to enable data filtering based on the user's needs. Here, we present a significant expansion of the Drosophila Genome Nexus, which brings the current data object to a total of 1,121 wild-derived genomes. New additions include 305 previously unpublished genomes from inbred lines representing six population samples in Egypt, Ethiopia, France, and South Africa, along with another 193 genomes added from recently-published data sets. We also provide an aligned D. simulans genome to facilitate divergence comparisons. This improved resource will broaden the range of population genomic questions that can addressed from multi-population allele frequencies and haplotypes in this model species. The larger set of genomes will also enhance the discovery of functionally relevant natural variation that exists within and between populations. © The Author 2016.

    2017-01-01

    Chest imaging plays a prominent role in blunt trauma patient evaluation, but indiscriminate imaging is expensive, may delay care, and unnecessarily exposes patients to potentially harmful ionizing radiation. To improve diagnostic chest imaging utilization, we conducted 3 prospective multicenter studies over 12years to derive and validate decision instruments (DIs) to guide the use of chest x-ray (CXR) and chest computed tomography (CT). The first DI, NEXUS Chest x-ray, consists of seven criteria (Age >60years; rapid deceleration mechanism; chest pain; intoxication; altered mental status; distracting painful injury; and chest wall tenderness) and exhibits a sensitivity of 99.0% (95% confidence interval [CI] 98.2-99.4%) and a specificity of 13.3% (95% CI, 12.6%-14.0%) for detecting clinically significant injuries. We developed two NEXUS Chest CT DIs, which are both highly reliable in detecting clinically major injuries (sensitivity of 99.2%; 95% CI 95.4-100%). Designed primarily to focus on detecting major injuries, the NEXUS Chest CT-Major DI consists of six criteria (abnormal CXR; distracting injury; chest wall tenderness; sternal tenderness; thoracic spine tenderness; and scapular tenderness) and exhibits higher specificity (37.9%; 95% CI 35.8-40.1%). Designed to reliability detect both major and minor injuries (sensitivity 95.4%; 95% CI 93.6-96.9%) with resulting lower specificity (25.5%; 95% CI 23.5-27.5%), the NEXUS CT-All rule consists of seven elements (the six NEXUS CT-Major criteria plus rapid deceleration mechanism). The purpose of this review is to synthesize the three DIs into a novel, cohesive summary algorithm with practical implementation recommendations to guide selective chest imaging in adult blunt trauma patients.

    According to Messages from the Bonn2011 Conference, involving local communities fully and effectively in the planning and implementation processes related to water, energy and food nexus for local ownership and commitment should be strongly needed. The participatory approaches such as deliberative polling, "joint fact-finding" and so on have been applied so far to resolve various environmental disputes, however the drivers and barriers in such processes have not been necessarily enough analyzed in a comprehensive manner, especially in Japan. Our research aims to explore solutions for conflicts in the context of water-energy-food nexus in local communities. To achieve it, we clarify drivers and barriers of each approaches applied so far in water, energy and food policy, focusing on how to deal with scientific facts. We generate hypotheses primarily that multi-issue solutions through policy integration will be more effective for conflicts in the context of water-energy-food nexus than single issue solutions for each policy. One of the key factors to formulate effective solutions is to integrate "scientific fact (expert knowledge)" and "local knowledge". Given this primary hypothesis, more specifically, we assume that it is effective for building consensus to provide opportunities to resolve the disagreement of "framing" that stakeholders can offer experts the points for providing scientific facts and that experts can get common understanding of scientific facts in the early stage of the process. To verify the hypotheses, we develop a database of the cases which such participatory approaches have been applied so far to resolve various environmental disputes based on literature survey of journal articles and public documents of Japanese cases. At present, our database is constructing. But it's estimated that conditions of framing and providing scientific information are important driving factors for problem solving and consensus building. And it's important to refine

    This study aimed to compare the diagnostic accuracy of NEXUS chest and Thoracic Injury Rule out criteria (TIRC) models in predicting the risk of intra-thoracic injuries following blunt multiple trauma. In this diagnostic accuracy study, using the 2 mentioned models, blunt multiple trauma patients over the age of 15 years presenting to emergency department were screened regarding the presence of intra-thoracic injuries that are detectable via chest x-ray and screening performance characteristics of the models were compared. In this study, 3118 patients with the mean (SD) age of 37.4 (16.9) years were studied (57.4% male). Based on TIRC and NEXUS chest, respectively, 1340 (43%) and 1417 (45.4%) patients were deemed in need of radiography performance. Sensitivity, specificity, and positive and negative predictive values of TIRC were 98.95%, 62.70%, 21.19% and 99.83%. These values were 98.61%, 59.94%, 19.97% and 99.76%, for NEXUS chest, respectively. Accuracy of TIRC and NEXUS chest models were 66.04 (95% CI: 64.34-67.70) and 63.50 (95% CI: 61.78-65.19), respectively. TIRC and NEXUS chest models have proper and similar sensitivity in prediction of blunt traumatic intra-thoracic injuries that are detectable via chest x-ray. However, TIRC had a significantly higher specificity in this regard. Copyright © 2018 Elsevier Ltd. All rights reserved.

    Interactive data analytics are playing an increasingly vital role in the generation of new, critical insights regarding the complex dynamics of the energy/water nexus (EWN) and its interactions with climate variability and change. Integration of impacts, adaptation, and vulnerability (IAV) science with emerging, and increasingly critical, data science capabilities offers a promising potential to meet the needs of the EWN community. To enable the exploration of pertinent research questions, a web-based geospatial visualization platform is being built that integrates a data analysis toolbox with advanced data fusion and data visualization capabilities to create a knowledge discovery framework for the EWN. The system, when fully built out, will offer several geospatial visualization capabilities including statistical visual analytics, clustering, principal-component analysis, dynamic time warping, support uncertainty visualization and the exploration of data provenance, as well as support machine learning discoveries to render diverse types of geospatial data and facilitate interactive analysis. Key components in the system architecture includes NASA's WebWorldWind, the Globus toolkit, postgresql, as well as other custom built software modules.

    2017-04-01

    On farm renewables diversify farm income sources (or reduce energy costs) and are thus generally considered to increase farm resilience. Whilst they clearly contribute to renewable energy production targets they can also affect water quality either positively (e.g. use of farmyard manure for anaerobic digestion) or negatively (particularly during construction). Here the interactions within the water-energy-food nexus are examined as they relate to on-farm renewables, where possible quantifying the relative magnitude of feedbacks between the three sectors. Particular focus is given to the dynamics of the system in changing climatic conditions. These analyses reveal a complex picture, with trade-offs between the 'resilience' in different parts of the nexus. This highlights the need for dialogue between stakeholders to identify the key functions in each sector that would be susceptible to particular climatic stresses so that these can be prioritised during planning.

    Achieving a long-term food security and preventing hunger include a better nutrition through sustainable systems of production, distribution, and consumption. Nonetheless, the quest for an alternative to increasing global food supply to meet the growing demand has led to the use of poor agricultural practices that promote climate change. Given the contribution of the agricultural ecosystem towards greenhouse gas (GHG) emissions, this study investigated the causal nexus between carbon dioxide emissions and agricultural ecosystem by employing a data spanning from 1961 to 2012. Evidence from long-run elasticity shows that a 1 % increase in the area of rice paddy harvested will increase carbon dioxide emissions by 1.49 %, a 1 % increase in biomass-burned crop residues will increase carbon dioxide emissions by 1.00 %, a 1 % increase in cereal production will increase carbon dioxide emissions by 1.38 %, and a 1 % increase in agricultural machinery will decrease carbon dioxide emissions by 0.09 % in the long run. There was a bidirectional causality between carbon dioxide emissions, cereal production, and biomass-burned crop residues. The Granger causality shows that the agricultural ecosystem in Ghana is sensitive to climate change vulnerability.

    Full Text Available Nexus 6P smartphones have been beset by battery drain issues, which have been causing premature shutdown of the phone even when the charge indicator displays a significant remaining runtime. To investigate the premature battery drain issue, two Nexus 6P smartphones (one new and one used were disassembled and their batteries were evaluated using computerized tomography (CT scan analysis, electrical performance (capacity, resistance, and impedance tests, and cycle life capacity fade tests. The “used” smartphone battery delivered only 20% of the rated capacity when tested in a first capacity cycle and then 15% of the rated capacity in a second cycle. The new smartphone battery exceeded the rated capacity when first taken out of the box, but exhibited an accelerated capacity fade under C/2 rate cycling and decreased to 10% of its initial capacity in just 50 cycles. The CT scan results revealed the presence of contaminant materials inside the used battery, raising questions about the quality of the manufacturing process.

  20. The Energy-Water Nexus: Managing the Links between Energy and Water for a Sustainable Future

    Hussey, Karen; Petit, Carine

    2010-05-01

    Water and energy are both indispensable inputs to modern economies but currently both resources are under threat owing to the impacts of an ever-increasing population and associated demand, unsustainable practices in agriculture and manufacturing, and the implications of a changing climate. However, it is where water and energy rely on each other that pose the most complex challenges for policy-makers. Water is needed for mining coal, drilling oil, refining gasoline, and generating and distributing electricity; and, conversely, vast amounts of energy are needed to pump, transport, treat and distribute water, particularly in the production of potable water through the use of desalination plants and waste water treatment plants. Despite the links, and the urgency in both sectors for security of supply, in existing policy frameworks energy and water policies are developed largely in isolation from one another. Worse still, some policies designed to encourage alternative energy supplies give little thought to the resultant consequences on water resources, and, similarly, policies designed to secure water supplies pay little attention to the resultant consequences on energy use. The development of new technologies presents both opportunities and challenges for managing the energy-water nexus but a better understanding of the links between energy and water is essential in any attempt to formulate policies for more resilient and adaptable societies. The energy-water nexus must be adequately integrated into policy and decision-making or governments run the risk of contradicting their efforts, and therefore failing in their objectives, in both sectors. A series of COST Exploratory Workshops, drawing on on-going research in the energy-water nexus from a number of international teams, identified the implications of the energy-water nexus on the development of (i) energy policies (ii) water resource management policies and (iii) climate adaptation and mitigation policies.

    Full Text Available The two major conservation issues for drylands of Africa are habitat loss or degradation and habitat fragmentation, largely from agriculture, charcoal production, and infrastructural development. A key question for management is how these landscapes can retain their critical ecological functions and services, while simultaneously supporting resilient livelihoods. It is a clear nexus question involving food (agriculture, water, and energy (fuelwood, which is complicated by human–wildlife conflicts. While these could appear disparate issues, they are closely connected in dryland forest landscapes of Africa where elephants occur close to areas of human habitation. For instance, crop failure, whether due to weather or wildlife damage, is a key driver for rural farmers seeking alternative livelihoods and incomes, one of the commonest being charcoal production. Similarly, heavy reliance on wood-based energy often leads to degradation of wildlife habitat, which heightens competition with wildlife for food and water, increasing the possibility of crop-raiding. So, for multifunctional landscapes where elephants occur in close proximity with humans, any food–water–energy nexus activities toward achieving sustainability and resilience should consider human–elephant conflicts (HECs. Here, we broach these food–water–energy nexus issues with a focus on dryland areas of Africa and HECs. We highlight an ongoing study attempting to address this nexus holistically by employing a climate-smart agriculture (CSA and agro-forestry based design, augmented by an elephant deterrent study and an eco-charcoal production venture.

    Chini, Christopher M.; Stillwell, Ashlynn S.

    2018-03-01

    Data on urban water resources are scarce, despite a majority of the U.S. population residing in urban environments. Further, information on the energy required to facilitate the treatment, distribution, and collection of urban water are even more limited. In this study, we evaluate the energy-for-water component of the energy-water nexus by providing and analyzing a unique primary database consisting of drinking water and wastewater utility flows and energy. These anthropogenic fluxes of water through the urban environment are used to assess the state of the U.S. urban energy-water nexus at over 160 utilities. The average daily per person water flux is estimated at 560 L of drinking water and 500 L of wastewater. Drinking water and wastewater utilities require 340 kWh/1,000 m3 and 430 kWh/1,000 m3 of energy, respectively, to treat these resources. The total national energy demand for water utilities accounts for 1.0% of the total annual electricity consumption of the United States. Additionally, the water and embedded energy loss associated with non-revenue water accounts for 9.1 × 109 m3 of water and 3,100 GWh, enough electricity to power 300,000 U.S. households annually. Finally, the water flux and embedded energy fluctuated monthly in many cities. As the nation's water resources become increasingly scarce and unpredictable, it is essential to have a set of empirical data for continuous evaluation and updates on the state of the U.S. urban energy-water nexus.

  4. Hydrogen Economy Model for Nearly Net-Zero Cities with Exergy Rationale and Energy-Water Nexus

    Directory of Open Access Journals (Sweden)

    Birol Kılkış

    2018-05-01

    Full Text Available The energy base of urban settlements requires greater integration of renewable energy sources. This study presents a “hydrogen city” model with two cycles at the district and building levels. The main cycle comprises of hydrogen gas production, hydrogen storage, and a hydrogen distribution network. The electrolysis of water is based on surplus power from wind turbines and third-generation solar photovoltaic thermal panels. Hydrogen is then used in central fuel cells to meet the power demand of urban infrastructure. Hydrogen-enriched biogas that is generated from city wastes supplements this approach. The second cycle is the hydrogen flow in each low-exergy building that is connected to the hydrogen distribution network to supply domestic fuel cells. Make-up water for fuel cells includes treated wastewater to complete an energy-water nexus. The analyses are supported by exergy-based evaluation metrics. The Rational Exergy Management Efficiency of the hydrogen city model can reach 0.80, which is above the value of conventional district energy systems, and represents related advantages for CO2 emission reductions. The option of incorporating low-enthalpy geothermal energy resources at about 80 °C to support the model is evaluated. The hydrogen city model is applied to a new settlement area with an expected 200,000 inhabitants to find that the proposed model can enable a nearly net-zero exergy district status. The results have implications for settlements using hydrogen energy towards meeting net-zero targets.

    Mroue, A. M.

    2017-12-01

    The future energy portfolio at the national and subnational levels should consider its impact on water resources and environment. Although energy resources are the main contributors to the national economic growth, these resources must not exploit other primary natural resources. A study of the connections between energy and natural systems, such as water, environment and land is required prior to proceeding to energy development. Policy makers are in need of a tool quantifying the interlinkages across energy, water and the environment, while demonstrating the consequent trade-offs across the nexus systems. The Energy Portfolio Assessment Tool (EPAT) is a tool that enables the policy maker to create different energy portfolio scenarios with various energy and electricity sources, and evaluate the scenario's sustainability environmentally and economically. The Water-Energy-Food nexus systematic approach is the foundation of the EPAT framework. The research evaluates the impact of the current and projected Texas energy portfolios on water and the environment, taking into consideration energy production, electricity generation and policy change. The three scenarios to be assessed include EIA projections for energy production, and EIA projections for electricity generation with and without the Clean Power Plan (CPP). Each scenario is accompanied by tradeoffs across water, land, emissions, energy revenue and electricity cost. The CPP succeeds in mitigating the emissions of the electricity portfolio, but leads to an increase in water consumption and land use. The cost of electricity generation is almost identical with and without environmental conservation. Revenue from energy production increased, but results are majorly influenced by commodity price. Therefore, conservation policies should move from the silo to the nexus mentality to avoid unintended consequences as improving one part of the nexus could end up worsening the other parts.

  7. On the income–nuclear energy–CO2 emissions nexus revisited

    Baek, Jungho; Pride, Dominique

    2014-01-01

    This paper seeks to contribute to the debate over the income–nuclear enery–CO 2 emissions nexus by taking specific account of the possible endogeneity of income, which has been largely ignored by early studies. A multivariate cointegrated vector autoregression (CVAR) is applied to top six nuclear generating countries. We find that nuclear energy tends to reduce CO 2 emission for all countries. It is also found that income has a beneficial effect on the environment only in some countries. Finally, we find that CO 2 emissions and income are indeed determined simultaneously, while nuclear energy acts exogenously, indicating that nuclear energy is the driving variable, which significantly influences the long-run movements of CO 2 emissions and income, but is not affected by CO 2 emissions and income in the model. - Highlights: • We examine the income–nuclear energy–CO 2 emissions nexus in top six nuclear generating countries. • The model pays special attention to the possible endogeneity of income. • Nuclear energy is found to have a beneficial effect on the environment in all countries. • Income has a favorable effect on the environment only in some countries. • CO 2 emissions and income are indeed found to be determined simultaneously

    This paper examines the nexus between CO 2 emissions, energy consumption and economic growth using simultaneous-equations models with panel data of 14 MENA countries over the period 1990–2011. Our empirical results show that there exists a bidirectional causal relationship between energy consumption and economic growth. However, the results support the occurrence of unidirectional causality from energy consumption to CO 2 emissions without any feedback effects, and there exists a bidirectional causal relationship between economic growth and CO 2 emissions for the region as a whole. The study suggests that environmental and energy policies should recognize the differences in the nexus between energy consumption and economic growth in order to maintain sustainable economic growth in the MENA region. - Graphical abstract: Interaction between CO 2 , energy and GDP for MENA countries. - Highlights: • We investigate the energy–environment–GDP nexus for 14 MENA countries. • We have used simultaneous equations models estimated by the GMM-estimator. • Results show bi-directional causal relationship between energy consumption and economic growth. • There is uni-directional causality from energy consumption to CO 2 . • There exists bi-directional causal relationship between economic growth and pollutant emissions

    Developing countries have experienced crucial conditions in meeting the needs for food, energy, and water security. This paper presents a country-level quantitative assessment of the current issues associated with the Food-Energy-Water-Security (FEWS) Nexus in the Middle East region. In this study, sixteen countries in the Middle East region are chosen, namely, Arabian Peninsula, Iran, Syria, Lebanon, Israel, Palestine, Egypt, and Turkey. The most recent datasets are used to study and analyze the factors that have emerged the demand to understand and manage the linkage of FEW systems in the region. Water scarcity, extreme events, population growth, urbanization, economic growth, poverty, and political stability are found to be the key drivers of the current challenges in the Middle East region. Additionally, the results suggest that these factors have created a subsequent stress on FEW resources specifically on water sector in the region. Therefore, more attention is required to sustain the FEW resources and cope with the socio-economic development.

    With an exponential increase in urbanization and industrialization, water pollution is an inevitable consequence of relatively lagging wastewater treatment facilities. The conventional activated sludge process for wastewater treatment primarily emphasizes the removal of harmful substances to maintain increasingly stringent effluent discharged standards, which is considered an energy-intensive technique. Therefore, innovative and sustainable wastewater treatment should pay more attention to energy and resource recovery in dealing with fossil fuel depletion, global-scale energy security, and climate change. A bibliometric analysis was applied to trace wastewater-energy nexus-related research during the period 1991 to 2015, with respect to the Science Citation Index EXPANDED (SCI-EXPANDED) database. Journal of Hazardous Materials, ranking 1st in h-index (79), was the most productive journal (431, 4.5%) during the same time, followed by International Journal of Hydrogen Energy (422, 4.4%) and Water Research (393, 4.1%) journal, the latter owning a topmost journal impact factor. Though, China (2154, 22.5%) was the most productive country, while the USA with highest h-index (88) was the favorest collaborative country. The Chinese Academy of Sciences, China (241, 2.5%) produced the maximum publications. A novel method called "word cluster analysis" showed that the emerging sustainable processes and novel renewable energy application are applied in response to the desire for a net wastewater-energy nexus system. Based on different wastewater types, the emerging energy and sources recovery treatment processes of Anammox, anaerobic digestion, and microbial fuel cells gained extensive innovation. Evaluation indicators including sustainability, life cycle assessment, and environmental impact were appropriately used to dissert feasibility of the novel treatment methods in regard of renewable energy utilization, energy savings, and energy recovery.

    2018-01-01

    Studies on the food, energy, and water (FEW) nexus lay a shared foundation for researchers, policy makers, practitioners, and stakeholders to understand and manage linked production, utilization, and security of FEW systems. The FEW nexus paradigm provides the water community specific channels to move forward in interdisciplinary research where integrated water resources management (IWRM) has fallen short. Here, we help water researchers identify, articulate, utilize, and extend our disciplinary strengths within the broader FEW communities, while informing scientists in the food and energy domains about our unique skillset. This paper explores the relevance of existing and ongoing scholarship within the water community, as well as current research needs, for understanding FEW processes and systems and implementing FEW solutions through innovations in technologies, infrastructures, and policies. Following the historical efforts in IWRM, hydrologists, water resources engineers, economists, and policy analysts are provided opportunities for interdisciplinary studies among themselves and in collaboration with energy and food communities, united by a common path to achieve sustainability development goals.

    Policy- and decision-making at the food-energy-water (FEW) nexus entails additional complexities due to the multi-objective nature of FEW socio-technical systems: policies and decisions meant to improve one facet of the nexus might be less beneficial, or even detrimental, to achieving goals for other facets. In addition, implementing policies and decisions may be more difficult due to increasing coordination required among stakeholders across each nexus facet. We highlight these issues in an economic, material/energy flow, and institutional assessment of dairy farms that produce power from anaerobic digestion of cow manure. This socio-technical system is an example of an integrated food-energy system (IFES), which co-produces food and energy. In the case of dairy farms, water is also a significant consideration because cow manure, if improperly managed, can negatively impact water bodies. Our assessment asks the questions (i) of whether or not adopting an IFES improves farm resilience under potential economic and environment futures and (ii) how decisions, policies, and information can best be tailored to the FEW nexus. Our study consists of semi-structured interviews of 60 farms split between the US states of New York and Vermont, both of which have enacted policies to encourage digester adoption. Each interview asks farmers about their material and energy flows, costs, and decision-making process for adopting (or not) an anaerobic digester. In addition, farmers are asked questions about challenges and barriers they might have faced and future drivers of change. Preliminary results highlight important interactions between policy and decision-making. Foremost, an analysis of policy cohesion shows that environmental objectives cross sectors and governance levels, as state-level greenhouse gas mitigation policies interact with federal-level nutrient management policies. This form of potential policy incoherence may introduce additional problems that hinder digester

    2015-12-01

    The world economy is under pressure for greater, more efficient and more sustainable use of natural resources to meet complementary and competing objectives in the energy, water, and food sectors. Increasing national, regional, and seasonal water scarcities in much of the world pose severe challenges for national governments, the international development community, and ultimately, for individual water users. This presentation assesses the nexus between energy and water, with an emphasis on the interactions and trade-offs between energy and water for food production. It examines the impact of biofuel production on water quantity and quality, and the potential for hydropower potential to meet energy challenges while expanding irrigation water supplies and food production potential, thereby enhancing global food security. Biofuel production affects both water quantity and quality. Expanding production of biofuels—through either crop-based production systems or direct biomass production—can significantly increase demand for water as more acreage is planted or the crop mix begins to favor thirstier crops; water demand for bio-refineries creates additional competition with agricultural water use. Water quality can also be adversely affected by increased acreage for fertilizer-intensive crops, such as maize or sugarcane, which can result in increased nitrate run-off and soil erosion. Hydropower has become a relatively forgotten part of the energy-water security picture that deserves renewed attention. Unlike biofuels, hydropower does not normally compete with agricultural water. Instead, development of hydropower could complement food production by developing dam structures and power that also provide irrigation water and support its distribution for growing food crops. But balanced hydropower policies require consideration of potential trade-offs with environmental and social impacts.

    Given their complexity and the number of stakeholders involved, it is difficult to solve social issues or problems based on an analysis that focuses on a single dimension. In particular, research surrounding climate change is inherently multidisciplinary and there is a need for highly pluralistic nexuses that can be used as a framework for policy decisions. Here, we suggest to water-centric nexus on agriculture and forest sector to improve response to climate change. The nexus is composed agricultural water demand and forest water supply to enhancing water-related adaptation to climate change in the Korean Peninsula. Agricultural productivity and water use related variables was estimating by EPIC crop model, and InVEST model applied for estimation of forest water supply. Results under two climate change scenarios (RCP4.5 and 8.5) and time period (2050s and 2070s), the forest water supply for the all future climate scenarios will increase significantly. In case of agriculture, irrigated crops experienced only the benefits of climate change, but rainfed crops were negatively impacted. It was also found that crop irrigation demand in the future is expected to be around twice as high as baseline levels, thus making irrigation more difficult to successfully implement. These hydrological threats have the potential to greatly reduce food security. In the nexus perspectives, the drop in the productivity of rainfed crops and the increase in irrigation demand in the agriculture sector can be resolved through interconnections with the forest sector. Appropriate management of the water supply in future climatic conditions characterized by increasing precipitation can maintain and expand agricultural areas through irrigation. To achieve this, a time-series water supply versus demand analysis must be performed so that an accurate balance between supply and demand can be established. Water-centric interactions of the agriculture and forest are the basis of nexus-based adaptation

    There is a strong relationship between organised crime and civil war. This article contributes to the crime-conflict nexus literature by providing a consideration of the role of organised crime in the Syrian conflict. It provides an overview of pre- and post-war organised crime in Syria. The article then builds the argument that war provides opportunities for organised crime through the state’s diminished law enforcement ability; the economic hardship which civilians face during war; and the ...

  20. Water-ecosystem-economy nexus under human intervention and climate change: a study in the Heihe River Basin (China)

    Recently, "One Belt and One Road" initiative, namely, building the "Silk Road Economic Belt" and "21st Century Maritime Silk Road", has become a global strategy of China and has been discussed as China's "Marshall Plan". The overland route of "One Belt" comes across vast arid lands, where the local population and ecosystem compete keenly for limited water resources. Water and environmental securities represent an important constraint of the "One Belt" development, and therefore understanding the complex water-ecosystem-economy nexus in the arid inland areas is very important. One typical case is Heihe River Basin (HRB), the second largest inland river basin of China, where the croplands in its middle part sucked up the river flow and groundwater, causing serious ecological problems in its lower part (Gobi Desert). We have developed an integrated hydrological-ecological model for the middle and lower HRB (the modeling domain has an area of 90,589 km2), which served as a platform to fuse multi-source data and provided a coherent understanding on the regional water cycle. With this physically based model, we quantitatively investigated how the nexus would be impacted by human intervention, mainly the existing and potential water regulations, and what would be the uncertainty of the nexus under the climate change. In studying the impact of human intervention, simulation-optimization analyses based on surrogate modeling were performed. In studying the uncertainty resulted from the climate change, outputs of multiple GCMs were downscaled for this river basin to drive ecohydrological simulations. Our studies have demonstrated the significant tradeoffs among the crop production in the middle HRB, the water and environmental securities of the middle HRB, and the ecological health of the lower HRB. The underlying mechanisms of the tradeoffs were also systematically addressed. The climate change would cause notable uncertainty of the nexus, which makes the water resources

    Full Text Available This paper examines the finance-growth nexus in Russia with the vector autoregression model, taking oil prices and foreign exchange rates into account. The analyzed period is from 1999 through 2008 (Subperiod 1 and from 2009 through 2014 (Subperiod 2. The results for Subperiod 1 suggest that there is causality from economic growth to money supply and bank lending, which implies demand-following responses. The results for Subperiod 2 show that economic growth Granger causes bank lending while there is no causality from money supply to economic growth, which could be related to the dramatic decrease in the amount of intervention in foreign exchange markets.

    The use of chest computed tomography (CT) to evaluate emergency department patients with adult blunt trauma is rising. The NEXUS Chest CT decision instruments are highly sensitive identifiers of adult blunt trauma patients with thoracic injuries. However, many patients without injury exhibit one of more of the criteria so cannot be classified "low risk." We sought to determine screening performance of both individual and combined NEXUS Chest CT criteria as predictors of thoracic injury to inform chest CT imaging decisions in "non-low-risk" patients. This was a secondary analysis of data on patients in the derivation and validation cohorts of the prospective, observational NEXUS Chest CT study, performed September 2011 to May 2014 in 11 Level I trauma centers. Institutional review board approval was obtained at all study sites. Adult blunt trauma patients receiving chest CT were included. The primary outcome was injury and major clinical injury prevalence and screening performance in patients with combinations of one, two, or three of seven individual NEXUS Chest CT criteria. Across the 11 study sites, rates of chest CT performance ranged from 15.5% to 77.2% (median = 43.6%). We found injuries in 1,493/5,169 patients (28.9%) who had chest CT; 269 patients (5.2%) had major clinical injury (e.g., pneumothorax requiring chest tube). With sensitivity of 73.7 (95% confidence interval [CI] = 68.1 to 78.6) and specificity of 83.9 (95% CI = 83.6 to 84.2) for major clinical injury, abnormal chest-x-ray (CXR) was the single most important screening criterion. When patients had only abnormal CXR, injury and major clinical injury prevalences were 60.7% (95% CI = 52.2% to 68.6%) and 12.9% (95% CI = 8.3% to 19.4%), respectively. Injury and major clinical injury prevalences when any other single criterion alone (other than abnormal CXR) was present were 16.8% (95% CI = 15.2% to 18.6%) and 1.1% (95% CI = 0.1% to 1.8%), respectively. Injury and major clinical injury prevalences

    2017-01-01

    The paper explores the energy-growth nexus by incorporating the key financial indicators in case of newly industrializing, BRICS countries. Considering the heterogeneity across the panel, the combined panel cointegration results confirm the long-run association between all the underlying variables. The overall findings suggest that despite sustainable development measures-financial indicators, economic growth and trade openness spur energy intensity in BRICS countries. The results also validate the Kuznets curve hypothesis between energy consumption and financial development and, energy consumption and trade openness. It implies that financial development and capital accumulation contribute to energy efficiency after the threshold income level. The causality analysis corroborate the regression results. In the end some policy recommendations are made. - Highlights: • Combine cointegration approach to explore the energy-growth-trade-finance nexus. • All variables found to have long-run association evident from cointegration test. • The results confirm the existence of EKC hypothesis. • BRICS′ economic growth spurs demand for energy. • Financial development and trade provides sustainable development path.

    The areas of energy, water and food policy have numerous interwoven concerns ranging from ensuring access to services, to environmental impacts to price volatility. These issues manifest in very different ways in each of the three “spheres”, but often the impacts are closely related. Identifying these interrelationships a priori is of great importance to help target synergies and avoid potential tensions. Systems thinking is required to address such a wide swath of possible topics. This paper briefly describes some of the linkages at a high-level of aggregation – primarily from a developing country perspective – and via case studies, to arrive at some promising directions for addressing the nexus. To that end, we also present the attributes of a modelling framework that specifically addresses the nexus, and can thus serve to inform more effective national policies and regulations. While environmental issues are normally the ‘cohesive principle’ from which the three areas are considered jointly, the enormous inequalities arising from a lack of access suggest that economic and security-related issues may be stronger motivators of change. Finally, consideration of the complex interactions will require new institutional capacity both in industrialised and developing countries.

  6. The water-energy-food-climate-economics nexus: solving hunger and resource scarcity

    2011-12-01

    A nexus refers to the core or to interconnectivity across issues. Addressing the boundary interactions of traditional sectors in an interconnected world as human activities change the physical boundaries of land and climate is an emerging academic and governance discourse. Through contrasting examples from the US and India, I shed light on the descriptive aspects of these connections and feedbacks that define potential impacts or traps for societies, and ponder whether a massive conceptual or numerical Earth System Model can help inform outcomes, or whether there are dominant links at particular scales (physical, social, economic or biological) that characterize the emergent dynamics and define critical equilibrium or transient solutions in certain places. However, the real question is what next given the definition of the nexus? Here, I argue that given the current valuation and management structure of different resource sectors and the associated information flows and sensitivities, the interlinked energy-climate issues can emerge as useful drivers of improved productivity in water-food systems, thus promoting resource and environmental sustainability while promoting economic development. Thus, levers can be found that help steer the course of these complex interacting systems towards desirable sectoral outcomes.

    One of the important unknowns of current cosmology concerns the effects of the large scale distribution of matter on the formation and evolution of dark matter haloes and galaxies. One main difficulty in answering this question lies in the absence of a robust and natural way of identifying the large scale environments and their characteristics. This work summarizes the NEXUS+ formalism which extends and improves our multiscale scale-space MMF method. The new algorithm is very successful in tracing the Cosmic Web components, mainly due to its novel filtering of the density in logarithmic space. The method, due to its multiscale and hierarchical character, has the advantage of detecting all the cosmic structures, either prominent or tenuous, without preference for a certain size or shape. The resulting filamentary and wall networks can easily be characterized by their direction, thickness, mass density and density profile. These additional environmental properties allows to us to investigate not only the effect of environment on haloes, but also how it correlates with the environment characteristics.

    Highlights: ► Demonstrates the nexus between sorption and bioavailability of As and Cd in variable-charge soils. ► Liming variable-charge soils increase negative charge, thereby decreasing Cd bioavailability. ► Ageing of As and Cd increases their immobilization, thereby decreasing bioavailability. ► Phosphate enhances desorption and phytoavailability of As from sheep dip soil. ► Metal(loid)s transfer to food chain can be managed by controlling sorption reactions. -- Abstract: In this work, the nexus between sorption and bioavailability of arsenic (As) and cadmium (Cd) as affected by soil type, soil pH, ageing, and mobilizing agents were examined. The adsorption of As and Cd was examined using a number of allophanic and non-allophanic soils which vary in their charge components. The effect of pH and ageing on the bioavailability of As and Cd was examined using spiked soils in a plant growth experiment. The effect of phosphate (P)-induced mobility of As on its bioavailability was examined using a naturally contaminated sheep dip soil. The results indicated that the adsorption of both As and Cd varied amongst the soils, and the difference in Cd adsorption is attributed to the difference in surface charge. An increase in soil pH increased net negative charge by an average of 45.7 mmol/kg/pH thereby increasing cation (Cd) adsorption; whereas, the effect of pH on anion (As) adsorption was inconsistent. The bioavailability of As and Cd decreased by 3.31- and 2.30-fold, respectively, with ageing which may be attributed to increased immobilization. Phosphate addition increased the mobility and bioavailability of As by 4.34- and 3.35-fold, respectively, in the sheep dip soil. However, the net effect of P on As phytoavailability depends on the extent of P-induced As mobilization in soils and P-induced competition for As uptake by roots. The results demonstrate the nexus between sorption and bioavailability of As and Cd in soils, indicating that the effects of

    2003-01-01

    This document is an output from the OECD Development and Climate Change project, an activity being jointly overseen by the (Environment Policy Committee) Working Party on Global and Structural Policies (WPGSP), and the DAC (Development Assistance Committee) Working Party on Development Co-operation and Environment (WPENV). The overall objective of the project is to provide guidance on how to mainstream responses to climate change within economic development planning and assistance policies, with natural resource management as an overarching theme. This paper sketches out a broad framework to address the nexus of sustainable development and climate change. It also draws out some implications for the preparation of future case studies aimed at exploring the dynamics of climate change vulnerability and adaptation - especially when one goes beyond simple win-win outcomes, and confronts difficult trade-off situations among conflicting objectives. Section 2 introduces the concept of sustainable development; Section 3 links that concept to climate change. In section 4, tools and methods of integrating and analysing the social, economic, and environmental dimensions of this nexus are briefly presented. These ideas are illustrated in section 5, by applying them to specific examples involving climate-related problems across the full range of spatial scales - at the global, national-economy-wide, sub-national-sectoral, and local-project levels. Section 6 contains some concluding thoughts and a discussion of implications for case studies

  18. Chinese State-Owned Enterprise Investment in Mekong Hydropower: Political and Economic Drivers and Their Implications across the Water, Energy, Food Nexus

    Directory of Open Access Journals (Sweden)

    Nathanial Matthews

    2015-11-01

    Full Text Available Over the last decade, Chinese State-Owned Enterprises have emerged as among the most active investors in Mekong Basin hydropower development. This paper uses a political economy analysis to examine the forces that drive Chinese State-Owned Enterprises to invest in hydropower in the Mekong Basin. We focus our analysis on the Lancang (Upper Mekong River in China and in the Greater Mekong Subregion (GMS, with an emphasis on Cambodia. The analysis reveals how powerful political and economic forces from within China and the GMS influence the pace, location and scale of investments in hydropower. These forces include foreign exchange reserves, trade packages and foreign direct investment, and political alliances. Combining the political economy and nexus approaches, we conclude that although policies from China recognize interconnections across the nexus, political and economic forces craft narratives that downplay or disregard these nexus interconnections and trade-offs. This in turn, influences how trade-offs and interconnections in hydropower development are managed and recognized in both local and transboundary contexts, thereby, creating potentially significant negative impacts on livelihoods, food security and the environment.

    2014-05-01

    In recent years, there has been considerable interest in social capital theory in both research and policy arenas. Social capital has been associated with many aspects of improvements in health, environment and development. This paper assesses the theoretical support for a social capital based analysis of environment and health issues with a focus on the water-health nexus in low and middle income countries. We review conceptualisation of social capital by Pierre Bourdieu in relation to his concepts of "fields" and "habitus" as well as other conceptualisations of social capital by James Coleman and Robert Putnam. We integrate these authors' ideas with ecosocial analysis of social and geographical patterns of access to safe water, adequate sanitation and hygiene and the resulting health impacts. Further, we develop a conceptual framework for linking social capital and health through the water-health nexus. The framework focuses on the role of social capital in improving water-related knowledge, attitudes and practices as well as facilitating collective action towards improving access to water and sanitation. The proposed framework will facilitate critical engagement with the pathways through which social processes and interactions influence health within the context of access to water, sanitation and hygiene in low and middle income countries.

  1. Quantification of Water Energy Nexus for Sustainable Development at Local Level: Case Study of Tamil Nadu

    Grover, S.; Tayal, S.

    2014-12-01

    Interdependency between water and energy is generally transacted in trade-off mode; where either of the resource gets affected because of the other. Generally this trade-off is commonly known as water-energy nexus. Many studies have been undertaken in various parts of the world using various approaches to tease out the intricate nexus. This research has adopted a different approach to quantify the inter-dependency. The adopted approach made an attempt to tease out the nexus from demand side for both the resources. For water demand assessment PODIUM Sim model was used and for other parameters available secondary data was used. Using this approach percentage share of water for energy and energy for water was estimated. For an informed decision making and sustainable development, assessment was carried out at state level as most of the policies are made specifically for the state. The research was done for the southernmost state of India, Tamil Nadu which is a rapidly growing industrial hub. Tamil Nadu is energy and water intensive state and the analysis shows that the share of water demand from energy sector compared to water demand from other major sectors is miniscule. While, the energy demand in water sector for various processes in different sectors compared to energy demand as total has a comparable share of range 15-25%. This analysis indicated the relative risk sectors face in competition for the resource. It point outs that water sector faces fierce competition with other sectors for energy. Moreover, the results of the study has assessed that state has negative water balance, which may make access to water more energy intensive with time. But, a projection into future scenario with an assumption based on the ongoing policy program of improving irrigation efficiency was made. It provided a solution of a potential positive equilibrium which conserves both water and energy. This scenario gave promising results which indicated less of water demand from

    In this paper we provide an assessment of the water-energy nexus for Greece. More specifically, the amount of freshwater consumed per unit of energy produced is determined: for both conventional (lignite, diesel and fuel oil-fired) and advanced (combined operation of gas turbine) thermal power plants in the electricity generation sector; for extraction and refining activities in the primary energy production sector; and for the production of biodiesel that is used as a blend in the ultimately delivered automotive diesel fuel. In addition, the amount of electricity consumed for the purposes of water supply and sewerage is presented. In view of the expected effects of climate change in the Mediterranean region, the results of this study highlight the need for authorities to prepare a national strategy that will ensure climate resilience in both energy and water sectors of the country.

  4. Impacts of Decarbonisation on the Water-Energy-Land (WEL Nexus: A Case Study of the Spanish Electricity Sector

    Directory of Open Access Journals (Sweden)

    2018-05-01

    Full Text Available Over the last decades, combating climate change has been an important concern for policy makers. As a result, many policies have been designed towards this direction. Being electricity generation the focus of climate change mitigation policies, important changes are expected in this sector over the next few years as a result of the implementation of such policies. However, electricity production also generates other impacts on the water, energy and land (WEL nexus that must be further investigated. To shed some light to this issue, this paper presents and discusses the potential impacts on the water-energy-land nexus resulting from the decarbonisation of the Spanish electricity system impacts under two different long-term scenarios. Using a Life Cycle Assessment (LCA approach, a set of environmental impacts relevant for the nexus have been analysed for the current and future electricity generation technologies in Spain. Additionally, through the use of an optimization energy model—Times-Spain—the evolution of the electricity technologies in Spain until 2030, under two different scenarios and targets has been assessed. Taking into consideration such scenarios, the global warming, acidification, eutrophication, ecotoxicity, water consumption, resource depletion and land use impacts have been estimated. Results show that, over time, together with the decrease of greenhouse gas emission, acidification and eutrophication tend to decrease in both scenarios. On the contrary, ecotoxicity and resource use impacts tend to increase.

    Rapid population increase coupled with urbanization and industrialization has resulted in shortages of water in the Middle East. This situation is further exacerbated by global climate change due to greenhouse gas emissions. Recent research advocates that solutions to the global water security and scarcity crisis must involve water–energy nexus approaches. This means adopting policies and strategies that harmonize these inter-related sectors to minimize environmental impact while maximizing human benefit. In the case of Abu Dhabi, when designing and locating oil/gas refineries and associated power generation facilities, previous relevant decisions were based on simple economic and geographical grounds, such as nearness to oil rigs, pipelines, existing industries and port facilities, etc. The subsequent design and location of water abstraction and treatment works operated by the waste heat from these refining and/or power generation processes was catered for as an afterthought, meaning that there is now a mismatch between the water and energy supplies and demands. This review study was carried out to show how Abu Dhabi is trying now to integrate its water–energy sectors using a nexus approach so that future water/power infrastructure is designed optimally and operated in harmony, especially in regard to future demand. Based upon this review work, some recommendations are made for designers and policy makers alike to bolster the nexus approach that Abu Dhabi is pursuing. PMID:27023583

    2015-12-01

    Energy, water and food are critical resources for sustaining social development and human lives; human beings cannot survive without any one of them. Energy crises, water shortages and food security are crucial worldwide problems. The nexus of energy, water and food has received more and more attention in the past decade. Energy, water and food are closely interrelated; water is required in energy development such as electricity generation; energy is indispensable for collecting, treating, and transporting water; both energy and water are crucial inputs for food production. Changes of either of them can lead to substantial impacts on other two resources, and vice versa. Effective decisions should be based on thorough research efforts for better understanding of their complex nexus. Rapid increase of population has significantly intensified the pressures on energy, water and food. Addressing and quantifying their interactive relationships are important for making robust and cost-effective strategies for managing the three resources simultaneously. In addition, greenhouse gases (GHGs) are emitted in energy, water, food production, consequently making contributions to growing climate change. Reflecting environmental impacts of GHGs is also desired (especially, on the quality and quantity of fresh water resources). Thus, a socio-economic model is developed in this study to quantitatively address the complex connections among energy, water and food production. A synthetic problem is proposed to demonstrate the model's applicability and feasibility. Preliminary results related to integrated decisions on energy supply management, water use planning, electricity generation planning, energy facility capacity expansion, food production, and associated GHG emission control are generated for providing cost-effective supports for decision makers.

    This study reexamines the causal link between electricity consumption, economic growth and CO 2 emissions in the BRICS countries (i.e., Brazil, Russia, India, China, and South Africa) for the period 1990–2010, using panel causality analysis, accounting for dependency and heterogeneity across countries. Regarding the electricity–GDP nexus, the empirical results support evidence on the feedback hypothesis for Russia and the conservation hypothesis for South Africa. However, a neutrality hypothesis holds for Brazil, India and China, indicating neither electricity consumption nor economic growth is sensitive to each other in these three countries. Regarding the GDP–CO 2 emissions nexus, a feedback hypothesis for Russia, a one-way Granger causality running from GDP to CO 2 emissions in South Africa and reverse relationship from CO 2 emissions to GDP in Brazil is found. There is no evidence of Granger causality between GDP and CO 2 emissions in India and China. Furthermore, electricity consumption is found to Granger cause CO 2 emissions in India, while there is no Granger causality between electricity consumption and CO 2 emissions in Brazil, Russia, China and South Africa. Therefore, the differing results for the BRICS countries imply that policies cannot be uniformly implemented as they will have different effects in each of the BRICS countries under study. - Highlights: • We examine the nexus of electricity, GDP growth and CO 2 emissions in BRICS. • We take into account cross-sectional dependency and heterogeneity across countries. • Electricity–GDP: Feedback for Russia and conservation for South Africa. • CO 2 –GDP feedback for Russia, from GDP to CO 2 in SA, CO 2 to GDP in Brazil. • Only from electricity consumption to emissions for India

    ABSTRACT. Internationally, student nurses' attrition after clinical practice is an increasing problem (Hamshire, Willgoss, & Wibberley, 2012; Pilegård Jensen, 2006). A better understanding of 'becoming a nurse' as situated practice in the hospital wards might help avoid pitfalls in the clinical...... practice. Thus a thorough insight into the field is necessary in order to change it. Using nexus analysis (Scollon & Scollon, 2004, 2007) as an ethnographic framework a study of the development of a professional identity among student nurses in Denmark was conducted. Scollon and Scollon’s notions...... on 'navigate' and 'engage' in the field provided a frame to combine both discourse (Edley, 2014) document (Prior, 2003) and interaction analysis (Jordan & Henderson, 1995; Sacks, 1992) in order to grasp the crucial social actors (nurses, students, patients, relatives) and their daily routinized practice...

    Tourism is often employed as a vehicle for facilitating social-economic development, however its usefulness has been somewhat limited in relation to addressing social issues, and in particular, those issues relating to poverty. This is partly due to the lack of cross-sectoral interactions...... the creation and synergising of social innovation that addresses persistent social issues. Yet to date, the utility of cross-sectoral knowledge dynamics still remains largely under-researched in both the social entrepreneurship and tourism literature. This chapter introduces readers to the concept of knowledge...... dynamics and discusses knowledge dynamics in the tourism and social entrepreneurship nexus via a case study of community-based tourism in Mai Hich, Vietnam. We argue that by gaining an enhanced understanding of cross-sectoral knowledge dynamics, we can strengthen the overall praxis of tourism and social...

    ChIP-exo/nexus experiments rely on innovative modifications of the commonly used ChIP-seq protocol for high resolution mapping of transcription factor binding sites. Although many aspects of the ChIP-exo data analysis are similar to those of ChIP-seq, these high throughput experiments pose a number of unique quality control and analysis challenges. We develop a novel statistical quality control pipeline and accompanying R/Bioconductor package, ChIPexoQual, to enable exploration and analysis of ChIP-exo and related experiments. ChIPexoQual evaluates a number of key issues including strand imbalance, library complexity, and signal enrichment of data. Assessment of these features are facilitated through diagnostic plots and summary statistics computed over regions of the genome with varying levels of coverage. We evaluated our QC pipeline with both large collections of public ChIP-exo/nexus data and multiple, new ChIP-exo datasets from Escherichia coli. ChIPexoQual analysis of these datasets resulted in guidelines for using these QC metrics across a wide range of sequencing depths and provided further insights for modelling ChIP-exo data. © The Author(s) 2017.

    This study proposed a holistic three-fold scheme that synergistically optimizes the benefits of the Water-Food-Energy (WFE) Nexus by integrating the short/long-term joint operation of a multi-objective reservoir with irrigation ponds in response to urbanization. The three-fold scheme was implemented step by step: (1) optimizing short-term (daily scale) reservoir operation for maximizing hydropower output and final reservoir storage during typhoon seasons; (2) simulating long-term (ten-day scale) water shortage rates in consideration of the availability of irrigation ponds for both agricultural and public sectors during non-typhoon seasons; and (3) promoting the synergistic benefits of the WFE Nexus in a year-round perspective by integrating the short-term optimization and long-term simulation of reservoir operations. The pivotal Shihmen Reservoir and 745 irrigation ponds located in Taoyuan City of Taiwan together with the surrounding urban areas formed the study case. The results indicated that the optimal short-term reservoir operation obtained from the non-dominated sorting genetic algorithm II (NSGA-II) could largely increase hydropower output but just slightly affected water supply. The simulation results of the reservoir coupled with irrigation ponds indicated that such joint operation could significantly reduce agricultural and public water shortage rates by 22.2% and 23.7% in average, respectively, as compared to those of reservoir operation excluding irrigation ponds. The results of year-round short/long-term joint operation showed that water shortage rates could be reduced by 10% at most, the food production rate could be increased by up to 47%, and the hydropower benefit could increase up to 9.33 million USD per year, respectively, in a wet year. Consequently, the proposed methodology could be a viable approach to promoting the synergistic benefits of the WFE Nexus, and the results provided unique insights for stakeholders and policymakers to pursue

    Land-cover change from energy development, including solar energy, presents trade-offs for the production of food and the conservation of natural ecosystems. Solar energy plays a critical role in contributing to the alternative energy mix to mitigate climate change and meet policy milestones; however, the extent that solar energy development can mitigate land scarcity, water shortages, and conservation is understudied. Here, we test whether projected electricity needs for the state of California (CA, United States [US]) can be met within land-cover types that can also generate environmental, social and fiscal co-benefits (techno-ecological synergies) including: the built environment, salt-affected land, contaminated land, and water reservoirs (as floatovoltaics). Additionally, we analyze general spatial trends and patterns related to clustering and proximity of techno-ecological opportunities and land-cover types (e.g. contamination sites and cities). In total, the Central Valley, a globally significant agricultural region, encompasses 15% of CA, 8,415 km2 of which was identified as potentially synergistic land for solar energy. These areas comprise a capacity-based energy potential of 17,348 TWh y-1 for photovoltaic (PV) and 1,655 TWh y-1 for concentrating solar power (CSP). Accounting for technology efficiencies, this exceeds California's 2025 projected electricity demands up to 13 and 2 times for PV and CSP, respectively. Further, 60% of contaminated lands are clustered within and up to 10 km of the 10 most populated cities in the Central Valley, where energy is consumed. Our study underscores the potential of strategic renewable energy siting to mitigate environmental trade-offs typically coupled with energy development sprawl in landscapes characterized by complex nexus issues.

    2017-06-01

    Full Text Available Access to reliable and affordable energy is vital for sustainable development. In the off-grid areas of developing countries, decentralized energy solutions have received increasing attention due to their contributions to reducing poverty. However, most of the rural population in many developing countries still has little or no access to modern energy technologies. This paper assesses the factors that determine the successes and failures of decentralized energy solutions based on local harmonized case studies from heterogeneous contexts from Asia, sub-Saharan Africa, and South America. The case studies were analyzed through the coupled lenses of energy transition and the Water–Energy–Food Security (WEF Nexus. The findings indicate that access to modern decentralized energy solutions has not resulted in complete energy transitions due to various tradeoffs with the other domains of the WEF Nexus. On the other hand, the case studies point at the potential for improvements in food security, incomes, health, the empowerment of women, and resource conservation when synergies between decentralized energy solutions and other components of the WEF Nexus are present.

    To explore the connection between +6 nursing leadership and enhanced patient safety. Critical reports from the Institute of Medicine in 1999 and Francis QC report of 2013 indicate that healthcare organisations, inclusive of nursing leadership, were remiss or inconsistent in fostering a culture of safety. The factors required to foster organisational safety culture include supportive leadership, effective communication, an orientation programme and ongoing training, appropriate staffing, open communication regarding errors, compliance to policy and procedure, and environmental safety and security. As nurses have the highest patient interaction, and leadership is discernible at all levels of nursing, nurse leaders are the nexus to influencing organisational culture towards safer practices. The position of this article was to explore the need to form a nexus between safety culture and leadership for the provision of safe care. Safety is crucial in health care for patient safety and patient outcomes. A culture of safety has been exposed as a major influence on patient safety practices, heavily influenced by leadership behaviours. The relationship between leadership and safety plays a pivotal role in creating positive safety outcomes for patient care. A safe culture is one nurtured by effective leadership. Patient safety is the responsibility of all healthcare workers, from the highest executive to the bedside nurse, thus effective leadership throughout all levels is essential in engaging staff to provide high quality care for the best possible patient outcomes. © 2017 John Wiley & Sons Ltd.

    Meeting the growing demand for food, water, and energy for a densely populated country like India is a major challenge. Green Revolution helped to maintain the food security, with Government policies such as distribution of electricity at a subsidised rate, resulting in an unregulated withdrawal of groundwater. Thus, the depleting groundwater went unnoticed as the high agricultural productivity overshadowed it. Here we present a comprehensive analysis which assess the present status of the water-food-energy nexus in India. We find that with the growth of population and consequent increase in the food demands, the food production has also increased, and this has been made possible with the intensification of irrigation. However, during the recent decade (after 1996), the increase in food production has not been sufficient to meet its growing demands, precipitating a decline in the per-capita food availability. Also, there has been a decline in the groundwater storage in India during the last decade, as derived from the Gravity Recovery and Climate Experiment (GRACE) data. Regional studies reveal contrasting trends, where North-western India and the middle Ganga basin show a decrease in the groundwater storage as opposed to an increasing storage over western-central India. We also find that, after a drought, the groundwater storage drops but is unable to recover to its original condition even after good monsoon years. The groundwater storage reveals a very strong negative correlation with the electricity consumption for agricultural usage, which may also be considered as a proxy for groundwater pumped for irrigation in a region. The electricity usage for agricultural purposes has an increasing trend and, interestingly, it does not have any correlation with the monsoon rainfall. This reveals an important finding that the irrigation has been intensified irrespective of rainfall. This also resulted in a decreasing correlation between the food production and monsoon

    Joining the domains of practice, research and policy is an important aspect of boosting the quality performance required to tackle complex public health problems. "Joining domains" implies a departure from the linear and technocratic knowledge-translation approach. Integrating the practice, research and policy triangle means knowing its elements, appreciating the barriers, identifying possible cooperation strategies and studying strategy effectiveness under specified conditions.This article examines the dynamic process of developing an Academic Collaborative Centre for Public Health in the Netherlands, with the objective of achieving that the three domains of policy, practice and research become working partners on an equal footing. An interpretative hermeneutic approach was used to interpret the phenomenon of collaboration at the nexus between the three domains. The project was explicitly grounded in current organizational culture and routines, applied to nexus action. In the process of examination, we used both quantitative (e.g. records) and qualitative data (e.g., interviews and observations). The data were interpreted using the Actor-Network, Institutional Re-Design and Blurring the Boundaries theories. Results show commitment at strategic level. At the tactical level, however, managers were inclined to prioritize daily routine, while the policy domain remained absent. At the operational level, practitioners learned to do PhD research in real-life practice and researchers became acquainted with problems of practice and policy, resulting in new research initiatives. We conclude that working at the nexus is an ongoing process of formation and reformation. Strategies based on Institutional Re-Design theories in particular might help to more actively stimulate managers' involvement to establish mutually supportive networks.

  4. The Climate Change-Road Safety-Economy Nexus: A System Dynamics Approach to Understanding Complex Interdependencies

    2017-01-01

    Full Text Available Road accidents have the highest externality costs to society and to the economy, even when compared to the externality damages associated with air emissions and oil dependency. Road safety is one of the most complicated topics, which involves many interdependencies, and so, a sufficiently thorough analysis of roadway safety will require a novel system-based approach in which the associated feedback relationships and causal effects are given appropriate consideration. The factors affecting accident frequency and severity are highly dependent on economic parameters, environmental factors and weather conditions. In this study, we try to use a system dynamics modeling approach to model the climate change-road safety-economy nexus, thereby investigating the complex interactions among these important areas by tracking how they affect each other over time. For this purpose, five sub-models are developed to model each aspect of the overall nexus and to interact with each other to simulate the overall system. As a result, this comprehensive model can provide a platform for policy makers to test the effectiveness of different policy scenarios to reduce the negative consequences of traffic accidents and improve road safety.

    Energy-water-environment nexus is very important to attain COP21 goal, maintaining environment temperature increase below 2°C, but unfortunately two third share of CO2 emission has already been used and the remaining will be exhausted by 2050. A number of technological developments in power and desalination sectors improved their efficiencies to save energy and carbon emission but still they are operating at 35% and 10% of their thermodynamic limits. Research in desalination processes contributing to fuel World population for their improved living standard and to reduce specific energy consumption and to protect environment. Recently developed highly efficient nature-inspired membranes (aquaporin & graphene) and trend in thermally driven cycle\\'s hybridization could potentially lower then energy requirement for water purification. This paper presents a state of art review on energy, water and environment interconnection and future energy efficient desalination possibilities to save energy and protect environment.

    2016-12-01

    The nexus represents a multi-dimensional means of scientific enquiry encapsulating the complex and non-linear interactions between water, energy, food, environment with the climate, and wider implications for society. These resources are fundamental for human life but are negatively affected by climate change. Methods of analysis, which are currently used, were not built to represent complex systems and are insufficiently equipped to understand positive and negative externalities generated by interactions among different stakeholders involved in the nexus. In addition misalignment between the science that scientists produce and the evidence decision-makers need leads to a range of complexities within the science-policy interface. Adopting a bottom-up, participative approach, the results of five themed workshops organized in the UK (focusing on: shocks and hazards, infrastructure, local economy, governance and governments, finance and insurance) featuring 80 stakeholders from academia, government and industry allow us to map perceptions of opportunities and challenges of better informing decision making on climate change when there is a strong disconnect between the evidence scientists provide and the actions decision makers take. The research identified key areas where gaps could be bridged between science and action and explores how a knowledge co-production approach can help identify opportunities for building a more effective and legitimate policy agenda to face climate risks. Concerns, barriers and opportunities to better inform decision making centred on four themes: communication and collaboration, decision making processes, social and cultural dimensions, and the nature of responses to nexus shocks. In so doing, this analysis provides an assessment of good practice on climate decision-making and highlights opportunities for improvement to bridge gaps in the science-policy interface

  12. Enabling Water-Energy–Food Nexus: A New Approach for Sustainable Agriculture and Food Security in Mountainous Landlocked Countries

    Directory of Open Access Journals (Sweden)

    Tek Bahadur Gurung

    2016-12-01

    Full Text Available Majority of landlocked mountainous countries are poorly ranked in Human Development Index (HDI, mostly due to poor per capita agriculture production, increasing population, unemployment, expensive and delayed transportation including several other factors. Generally, economy of such countries substantially relies on subsistence agriculture, tourism, hydropower and largely on remittance etc. Recently, it has been argued that to utilize scarce suitable land efficiently for food production, poor inland transport, hydropower, irrigation, drinking water in integration with other developmental infrastructures, an overarching policy linking water - energy – food nexus within a country for combating water, energy and food security would be most relevant. Thus, in present paper it has been opined that promotion of such linkage via nexus approach is the key to sustainable development of landlocked mountainous countries. Major land mass in mountainous countries like Nepal remains unsuitable for agriculture, road and other infrastructure profoundly imposing food, nutrition and energy security. However, large pristine snowy mountains function as wildlife sanctuaries, pastures, watershed, recharge areas for regional and global water, food and energy security. In return, landlocked mountainous countries are offered certain international leverages. For more judicious trade off, it is recommended that specific countries aerial coverage of mountains would be more appropriate basis for such leverages. Moreover, for sustainability of mountainous countries an integrated approach enabling water - energy – food nexus via watershed-hydropower-irrigation-aquaculture-agriculture-integrated linking policy model is proposed. This model would enable protection of watershed for pico, micro, and mega hydro power plants and tail waters to be used for aquaculture or irrigation or drinking water purposes for food and nutrition security.

    The goal of this paper is to model the relationship between electricity consumption and real gross domestic product (GDP) for Malaysia in a bivariate and multivariate framework. We use time series data for the period 1971-2003 and apply the bounds testing approach to search for a long-run relationship. Our results reveal that electricity consumption, real GDP and price share a long-run relationship. The results of the autoregressive distributed lag (ARDL) estimates of long-run elasticity of electricity consumption on GDP are found to be around 0.7 and statistically significant. Finally, in the short-run, the results of the causality test show that there is a unidirectional causal flow from electricity consumption to economic growth in Malaysia. From these findings we conclude that Malaysia is an energy-dependent country, leading us to draw some policy implications. This paper adds support and validity, thus reducing the policy makers concern on the ambiguity of the electricity and growth nexus in Malaysia. (author)

    As agricultural land and freshwater inextricably interrelate and interact with each other, the conventional water and land policy in "silos" should give way to nexus thinking when formulating the land and water management strategies. This study constructs a systems multi-regional input-output (MRIO) model to expound global land-water nexus by simultaneously tracking agricultural land and freshwater use flows along the global supply chains. Furthermore, land productivity and irrigation water requirements of 160 crops in different regions are investigated to reflect the land-water linkage. Results show that developed economies (e.g., USA and Japan) and major large developing economies (e.g., mainland China and India) are the overriding drivers of agricultural land and freshwater use globally. In general, significant net transfers of these two resources are identified from resource-rich and less-developed economies to resource-poor and more-developed economies. For some crops, blue water productivity is inversely related to land productivity, indicating that irrigation water consumption is sometimes at odds with land use. The results could stimulus international cooperation for sustainable land and freshwater management targeting on original suppliers and final consumers along the global supply chains. Moreover, crop-specific land-water linkage could provide insights for trade-off decisions on minimizing the environmental impacts on local land and water resources. Copyright © 2017 Elsevier B.V.

    During the last three decades, following closely the developments in econometric theory, energy and environmental economists have empirically examined the energy-income nexus for different countries and time periods. However, today, in spite of the growing interest in this area, the state of knowledge is still controversial and unsettled. This viewpoint paper attempts to highlight some of the issues related to the existing literature on the long-run relationship and causality between energy consumption and economic growth. In particular, it discusses how it is difficult to make policy recommendations on the basis of inconsistent and conflicting results in the published literature on the subject. In order to do so, the paper first illustrates the increasing trend in the number of studies published in this area providing also a brief comparison of the conventional methods used to estimate the energy-income nexus. It then deals with new directions and different viewpoints on the same issue

    The first part of this presentation analyses which water footprint (WF) components are necessary in WF accounting to provide relevant information to address the Sustainable Development Goals (SDG's) water security (SDG 6), food security (SDG 2) and energy security (SDG 7) in a nexus setting. It is strongly based on the publication Vanham (2016) http://dx.doi.org/10.1016/j.ecoser.2015.08.003. First, the nexus links between (1) the planetary boundary freshwater resources (green and blue water resources) and (2) food, energy and blue water security are discussed. Second, it is shown which water uses are mostly represented in WF accounting. General water management and WF studies only account for the water uses agriculture, industry and domestic water. Important water uses are however mostly not identified as separate entities or even included, i.e. green and blue water resources for aquaculture, wild foods, biofuels, hydroelectric cooling, hydropower, recreation/tourism, forestry (for energy and other biomass uses) and navigation. Third, therefore a list of essential separate components to be included within WF accounting is presented. The latter would be more coherent with the water-food-energy-ecosystem nexus. The second part of the presentation gives a brief overview of the recently published Urban Water Atlas for Europe. It shows for a selected city which WF components are represented and which not. As such, it also identifies research gaps.

    Full Text Available Meeting the growing water and food demands in a densely populated country like India is a major challenge. It requires an extensive investigation into the changing patterns of the checks and balances behind the maintenance of food security at the expense of depleting groundwater, along with high energy consumption. Here we present a comprehensive set of analyses which assess the present status of the water–food–energy nexus in India, along with its changing pattern, in the last few decades. We find that with the growth of population and consequent increase in the food demands, the food production has also increased, and this has been made possible with the intensification of irrigation. However, during the recent decade (after 1996, the increase in food production has not been sufficient to meet its growing demands, precipitating a decline in the per-capita food availability. We also find a statistically significant declining trend of groundwater storage in India during the last decade, as derived from the Gravity Recovery and Climate Experiment (GRACE satellite datasets. Regional studies reveal contrasting trends between northern and western–central India. North-western India and the middle Ganga basin show a decrease in the groundwater storage as opposed to an increasing storage over western–central India. Comparison with well data reveals that the highest consistency of GRACE-derived storage data with available well measurements is in the middle Ganga basin. After analysing the data for the last 2 decades, we further showcase that, after a drought, the groundwater storage drops but is unable to recover to its original condition even after good monsoon years. The groundwater storage reveals a very strong negative correlation with the electricity consumption for agricultural usage, which may also be considered as a proxy for groundwater pumped for irrigation in a region.

    Water, energy, and food (WEF) are viewed as main systems forming a nexus, which itself is threatened by defined external factors mainly characterized by growing population, changing economies, governance, climate change, and international trade. Integrative thinking in strategic planning for natural resources comes through recognizing the intimate level of interconnectedness between these systems and the entities that govern them. Providing sustainable solutions to overcome present challenges pose the need to study the existent inter-linkages and tradeoffs between resources. In this context, the present communication is to present the WEF-nexus project, a Tunisian - Jordanian - Qatari - USA project which is funded by the USAID - FABRI PR&D Grants program. WEF-nexus project seeks to explore the inextricable link between water resources and food security in both its geophysical and socio-economic dimensions. The project proposes to design, implement and test integrated resource management tool based on the water-energy-food nexus framework that i) includes the evaluation of the tool over a wide range of climatic and socio-economic zones represented by different countries in the MENA region, and ii) develop scenarios with variations of resources, demands, constraints, and management strategies for the chosen countries, which would be used as a foundation for guiding decision making. The approach is implemented and tested within Tunisia, Jordan, and Qatar. Beyond the obtaining of significant advances in the aforementioned methodological domains, and the understanding of the problems and challenges related to water and food that societies are experiencing or will experience in the future, outcomes are expected to :i) engage decision makers in the process of improving current policies, and strengthening relevant public- private collaboration through the use of the proposed tool, and ii) help in revisiting former recommendations at the levels of resource governance, and

    South Asia in general and India in particular is heavily dependent on groundwater for supporting its largely agrarian population. Informal pump irrigation services markets have played an important role in providing access to irrigation to millions of small and marginal farmers and had positive equity, efficiency and sustainable impacts in water-abundant regions such as West Bengal. Quite predictably, in such pump lift-based economy, fortunes of energy and irrigation sectors are closely entwined. This has often been called the 'energy-irrigation' nexus. There are two major sources of energy for pumping groundwater, viz. electricity and diesel. Most of the current discourse in the field has looked only at the 'electricity-irrigation' nexus to the exclusion of the 'diesel-irrigation nexus'. This paper looks at both these aspects. In doing so, it makes two propositions. First, high flat-rate electricity tariff encourages development of water markets whereby the water buyers-who are mostly small and marginal farmers-benefit through access to irrigation. Second, low rate of rural electrification has forced majority of farmers to depend on diesel for groundwater pumping and the steep increase in diesel prices over the last few years has resulted in economic scarcity of groundwater. This in turn has had serious negative impacts on crop production and farm incomes. Using primary field data from West Bengal, India, this paper makes a case for rapid rural electrification and continuation of high flat-rate tariff, which would in turn support developed groundwater markets and provide access to irrigation to the poor and marginal farmers

    Freshwater use for food production is projected to increase substantially in the coming decades with population growth, changing demographics, and shifting diets. Ensuring joint food-water security has prompted efforts to quantify freshwater use for different food products and production methods. However, few analyses quantify freshwater use for seafood production, and those that do use inconsistent water accounting. This inhibits water use comparisons among seafood products or between seafood and agricultural/livestock products. This 'seafood gap' in the food-water nexus literature will become increasingly problematic as seafood consumption is growing globally and aquaculture is one of the fastest growing animal food sectors in the world. Therefore, the present study 1) reviews freshwater use concepts as they relate to seafood production; 2) provides three cases to highlight the particular water use concerns for aquaculture, and; 3) outlines future directions to integrate seafood into the broader food-water nexus discussion. By revisiting water use concepts through a focus on seafood production systems, we highlight the key water use processes that should be considered for seafood production and offer a fresh perspective on the analysis of freshwater use in food systems more broadly.

    Full Text Available This study aims to examine the impact of ethical leadership on employees' job satisfaction, job performance, and turnover intention. A conceptual framework is developed which integrates job satisfaction as a mediating mechanism in explaining the nexus among ethical leadership, employee job performance, and turnover intention. The proposed model is tested by using the data collected from a sample (n = 196 of tourist companies in Pakistan. The results reveal that ethical leadership has a positive effect on employees' job satisfaction, job performance and negative effect on employees' turnover intentions. Further, job satisfaction mediates the effect of ethical leadership on employees' job performance and turnover intentions. The findings recommend that the demonstration of ethical leadership behaviours by managers at the workplace increases the likelihood of employees' job satisfaction and performance, while reducing their intention to leave the job. This study elucidates that, in Pakistani tourism sector, ethical leadership plays a key role in achieving performance goals. Future research could analyse the said nexus in different sectors and across different cultures while considering other measures of individual performance. The originality of this study is theorizing as well as empirically testing the intervening mechanism of job satisfaction in probing the linkages among ethical leadership, job performance, and turnover intention in Pakistani workplace context.

    Mediator is an essential, large, multisubunit, transcriptional co-activator highly conserved across eukaryotes. Mediator interacts with gene-specific transcription factors at enhancers as well as with the RNA polymerase II (RNAPII) transcription machinery bound at promoters. It also interacts with several other factors involved in various aspects of transcription, chromatin regulation, and mRNA processing. Hence, Mediator is at the nexus of RNAPII transcription, regulating its many steps and connecting transcription with co-transcriptional events. To achieve this flexible role, Mediator, which is divided into several functional modules, reorganizes its conformation and composition while making transient contacts with other components. Here, we review the mechanisms of action of Mediator and propose a unifying model for its function. Copyright © 2017 Elsevier Ltd. All rights reserved.

    In southern Africa, the connections between climate and the water-energy-food nexus are strong. Physical and socioeconomic exposure to climate is high in many areas and in crucial economic sectors. Spatial interdependence is also high, driven, for example, by the regional extent of many climate anomalies and river basins and aquifers that span national boundaries. There is now strong evidence of the effects of individual climate anomalies, but associations between national rainfall and gross domestic product and crop production remain relatively weak. The majority of climate models project decreases in annual precipitation for southern Africa, typically by as much as 20% by the 2080s. Impact models suggest these changes would propagate into reduced water availability and crop yields. Recognition of spatial and sectoral interdependencies should inform policies, institutions and investments for enhancing water, energy and food security. Three key political and economic instruments could be strengthened for this purpose: the Southern African Development Community, the Southern African Power Pool and trade of agricultural products amounting to significant transfers of embedded water.

    Full Text Available This paper attempts to investigate the relationship among economic growth, energy consumption, CO2 emission, FDI and natural gas usage in Bangladesh through co-integration and Vector Error Correction model (VECM over the period 1978 to 2010. Using ADP unit root tests it is found that all the four variables are integrated in first difference. The Johansen co-integration tests indicate that there is existence of long-run relationship among the variables. The VECM long run causality model indicates that there is a long run causality running from energy consumption and natural gas usage by industrial sector to GDP as well as from CO2 emission to FDI. Likewise in the short run a causal relationships have also been found among the variables. Moreover our model is found be error free based on several statistical test. Our results provide important policy suggestions regarding our foreign direct investment, environmental issues and economic growth nexus in Bangladesh.

    Recent energy security strategies, investment opportunities and energy policies have led to an escalation in biofuel consumption at the expenses of food crops and pastureland. To evaluate the important impacts of biofuels on food security, the food-energy nexus needs to be investigated in the context of its linkages with the overall human appropriation of land and water resources. Here we provide a global assessment of biofuel crop production, reconstruct global patterns of biofuel crop/oil trade and determine the associated displacement of water and land use. We find that bioethanol is mostly produced with domestic crops while 36% of biodiesel consumption relies on international trade, mainly from Southeast Asia. Altogether, biofuels rely on about 2-3% of the global water and land used for agriculture, which could feed about 30% of the malnourished population. We evaluate the food-energy tradeoff and the impact an increased reliance on biofuel would have on the number of people the planet can feed.

    Full Text Available Spatial pattern, transportation, and air quality are three development entities which significantly affecting one another. This nexus exhibits the urbanization imprint accouter transportation generating air pollution as a reflection of spatial distribution. The integration among them is a vital part of development as it affects the societal living environment. It provides unfavorable air quality and directly cause health problems. The developing region of Iskandar Malaysia exhibits huge spatial distribution transformation accompanied by large percentage of urbanization rate, but seems less integration of land use and transportation planning which causes the exaggeration of air pollution. We carry out the research on the nexus of spatial distribution, transportation and air quality in Iskandar Malaysia by analyzing and evaluating the interconnectivity of these three entities. The spatial analysis and evaluation on the land use development pattern and spatial policy shows that the Iskandar development region are growing in the polycentric manners, where the spatial development policy drives the distributional growth of new sub-centers. We undertook a household-based travel survey that reveals the poly-centricity reflected by the de-concentration of workplaces which shifted from the single point towards multiple centers. On the other hand, this phenomenon has created a distributional traffic pattern amid the high dependency on the private vehicles of the citizens in Iskandar Malaysia. With a predominantly fossil fuel consuming vehicles, this has generated air pollution. Based on the traffic survey and the dependency of the citizens on private cars for their daily mobility, the concentration of air pollution is seemingly at risk. This research reflects that Iskandar Malaysia development region currently undergoes towards polycentric development with some new urban centers. We found that land use and transportation planning policies require serious

    Water resources management is already complex enough, given fragmented landscapes and institutions and uncertain climate and environmental conditions. But given the interdependence of water, energy, and land systems (the "energy-water-land nexus"), integrated approaches to cross-sectoral modeling and decision making that account for the interdependencies are increasingly important. This presentation will describe the context of the broader institutional and policy dimensions (e.g., cross-Federal research agencies) and scientific challenges of bringing the water, energy, and land research communities together (e.g., different epistemologies, data, modeling, and decision support methods). The speaker will describe efforts to develop a shared community of practice to improve research collaboration and provide insights on coupled system resilience.

    Nutrients and water found in domestic treated wastewater are valuable and can be reutilized in urban agriculture as a potential strategy to provide communities with access to fresh produce. In this paper, this proposition is examined by conducting a field study in the rapidly developing city of Hyderabad, India. Urban agriculture trade-offs in water use, energy use and GHG emissions, nutrient uptake, and crop pathogen quality are evaluated, and irrigation waters of varying qualities (treated wastewater, versus untreated water and groundwater) are compared. The results are counter-intuitive, and illustrate potential synergies and key constraints relating to the food-energy-water-health (FEW-health) nexus in developing cities. First, when the impact of GHG emissions from untreated wastewater diluted in surface streams is compared with the life cycle assessment of wastewater treatment with reuse in agriculture, the treatment-plus-reuse case yields a 33% reduction in life cycle system-wide GHG emissions. Second, despite water cycling benefits in urban agriculture, only contamination and farmer behavior and harvesting practices. The study uncovers key physical, environmental, and behavioral factors that constrain benefits achievable at the FEW-health nexus in urban areas.

    Climate change, extremes, and climate-driven disturbances are anticipated to have substantial impacts on regional water resources, particularly in the western and southwestern United States. These unprecedented conditions—a no-analog future—will result in challenges to adaptation, mitigation, and resilience planning for the energy-water-food nexus. We have analyzed the impact of climate change on Colorado River flows for multiple climate and disturbance scenarios: 12 global climate models and two CO2 emission scenarios (RCP 4.5 and RCP 8.5) from the Intergovernmental Panel on Climate Change's Coupled Model Intercomparison Study, version 5, and multiple climate-driven forest disturbance scenarios including temperature-drought vegetation mortality and insect infestations. Results indicate a wide range of potential streamflow projections and the potential emergence of a "new" Colorado River basin. Overall, annual streamflow tends to increase under the majority of modeled scenarios due to projected increases in precipitation across the basin, though a significant number of scenarios indicate moderate and potentially substantial reductions in water availability. However, all scenarios indicate severe changes in seasonality of flows and strong variability across headwater systems. This leads to increased fall and winter streamflow, strong reductions in spring and summer flows, and a shift towards earlier snowmelt timing. These impacts are further exacerbated in headwater systems, which are key to driving Colorado River streamflow and hence water supply for both internal and external basin needs. These results shed a new and important slant on the Colorado River basin, where an emergent streamflow pattern may result in difficulties to adjust to these new regimes, resulting in increased stress to the energy-water-food nexus.

    Technological advances and access to global markets have changed the rate at which resource exploitation takes place. The environmental impact of the rapid development and distribution of resources such as minerals and hydrocarbons has led to a greater potential for significant stress on water resources both in terms of quality and quantity. How and where those impacts manifest is crucial to determining appropriate risk management strategies. North East British Columbia has an abundance of shale gas reserves that are anticipated to be exploited at a large scale in coming years, primarily for export as liquefied natural gas (LNG). However, there is growing concern that fracking and other activities related to shale gas development pose risks to water quality and quantity in the region. Water lies at the center of the water-energy-food nexus, with an accelerating water demand for fracking and industrial operations as well as for domestic, environmental and agricultural uses. Climate change is also anticipated to alter the hydrologic regime, posing added stress to the water resource. This case study examines the water-energy-food nexus in the context of a region that is impacted by a rapidly developing resource sector, encompassing water demand/supply, climate change, interaction between deep aquifers and shallow aquifers/surface waters, water quality concerns related to fracking, land use disturbance, and community impacts. Due to the rapid rate of development, there are significant knowledge gaps in our understanding of the water resource. Currently agencies are undertaking water resource assessments and establishing monitoring sites. This research aims to assess water security in North East British Columbia in a coordinated fashion through various partnerships. In addition to collecting baseline knowledge and data, the study will evaluate risk and resilience indicators in relation to water security.

    This paper explores the water footprint (WF) of paddy rice and the nexus of water-land-food (rice) in Taiwan. The research results indicate that the average annual rice WF for the years 2005-2014 was about 7,580 m3/ton, of which 80% was blue, 17% was green, and 3% was grey. This average annual footprint was about 5.7 times larger than the 2000-2004 average annual WF of rice for countries around the globe of 1325 m3/ton, of which 48% was green, 44% was blue, and 8% was grey. The blue WF is the most important source of water for rice production in Taiwan. The water consumption of the second crop is higher than that of the first crop. The water use efficiency in the southern region of Taiwan is the best, while the northern part of Taiwan exhibits relatively high inefficiency. The rates of change in cultivated land and rice production in Taiwan are decreasing in a stable manner. However, the annual rate of change in the rice WF is unstable. The nexus of land, water, and food should be taken into consideration to protect water availability, maintain agricultural production, and avoid land degradation. The results could offer useful information for agriculture policy and water resource management.

    Whereas sub-Saharan Africa's (SSA) water scarcity, food, nutrition and health challenges are well-documented, efforts to address them have often been disconnected. Given that the region continues to be affected by poverty and food and nutrition insecurity at national and household levels, there is a need for a paradigm shift in order to effectively deliver on the twin challenges of food and nutrition security under conditions of water scarcity. There is a need to link water use in agriculture to achieve food and nutrition security outcomes for improved human health and well-being. Currently, there are no explicit linkages between water, agriculture, nutrition and health owing to uncoordinated efforts between agricultural and nutrition scientists. There is also a need to develop and promote the use of metrics that capture aspects of water, agriculture, food and nutrition. This review identified nutritional water productivity as a suitable index for measuring the impact of a water-food-nutrition-health nexus. Socio-economic factors are also considered as they influence food choices in rural communities. An argument for the need to utilise the region's agrobiodiversity for addressing dietary quality and diversity was established. It is concluded that a model for improving nutrition and health of poor rural communities based on the water-food-nutrition-health nexus is possible.

  17. A literature survey on energy-growth nexus

    2010-01-01

    This paper provides a survey of the recent progress in the literature of energy consumption-economic growth and electricity consumption-economic growth causality nexus. The survey highlights that most empirical studies focus on either testing the role of energy (electricity) in stimulating economic growth or examining the direction of causality between these two variables. Although the positive role of energy on growth has become a stylized fact, there are some methodological reservations about the results from these empirical studies. A general observation from these studies is that the literature produced conflicting results and there is no consensus neither on the existence nor on the direction of causality between energy consumption (electricity consumption) and economic growth. As a policy implication, to avoid from conflicting and unreliable results, the authors may use the autoregressive distributed lags bounds test, two-regime threshold co-integration models, panel data approach and multivariate models including new variables (such as: real gross fixed capital formation, labor force, carbon dioxide emissions, population, exchange rates, interest rates, etc.). Thus, the authors should focus more on the new approaches and perspectives rather than by employing usual methods based on a set of common variables for different countries and different intervals of time.

    The objective of this study is to examine the impacts of arbitrations on land use (choice between urban development, agriculture, infrastructures, forests, free spaces, and so on, which are concurrent and exclusive) on greenhouse gas emissions. The first part highlights the complexity of this issue as land use can both generate important greenhouse gas emissions (through deforestation, methane emission by cattle, nitrogenous fertilizers) and absorb large quantities of CO 2 . The second part analyses and discusses the extent and the reasons of deforestation, commenting the situation in developed countries and in the case of the tropical forest. The third part describes the competition between land uses, reviews existing economical models, and presents the Nexus Land Use model which could be able to integrate agricultural and forestry challenges at the planet scale

    Barber, Herbert Marion, Jr.

    The purpose of this study was to conduct an economic assessment of the construction industry. More specifically, this study addresses ambiguities within the literature that are associated with the construction-economics nexus. The researcher 1) investigated the relationships between economic indicators and stock prices of U.S. construction equipment manufacturers, 2) investigated the relationships between energy production, consumption, and corruption, and 3) determined the economic effect electricity generation and electricity consumption has on economies of scale. The researcher used descriptive and inferential statistics in this study and determined that economists, researchers, policy-makers, and others should have predicted the 2007-08 world economic collapse 5-6 years prior to realization of the event given that construction indices and GDP grossly regressed from statistically acceptable trends as early as 2002 and perhaps 2000. Substantiating this claim, the effect of the cost of construction materials and labor, i.e. construction index, on GDP was significant for years leading up to the collapse (1970-2007). Additionally, it was determined that energy production and consumption are predictors of governmental corruption in some countries. In the Republic of Botswana, for example, the researcher determined that energy production and consumption statistically jointly effected governmental corruption. In addition to determining statistical effect, a model for predicting governmental corruption was developed based on energy production and consumption volumes. Also, the researcher found that electricity generation in the 25 largest world economies had a statistically significant effect on GDP. Electricity consumption also had an effect on GDP, as well, but not on other economic indicators. More importantly than the quantitative findings, the researcher concluded that the construction-economics nexus is far more complex than most policy-makers realize. As such

    The NEXUS of water, energy and agriculture is widely recognized as an integrated approach for innovative management solutions and actions to protect natural resources. Soil Spectral Libraries (SSL) implement the NEXUS approach by combining Earth Observation (EO) and Geospatial Information (GI) data and tools to extract information on soil attributes rapidly, reliably and cost effectively. NEXUS approach for soil resources at large scales- across landscapes or regions- remains a challenge however, especially for stakeholders, and in regards to promoting the concept, disseminating the methodology, and discussing potential benefits at both local and transboundary river basin levels. The CEOS Data Cube is an excellent tool for collecting, processing and disseminating EO data, and providing `Analysis Ready Data' utilized both as a management tool for policy makers, and a tool boosting economic activity and supporting end-users. Thus, it helps supporting the tracking of, and reporting on, the Sustainable Development Goals (SDGs), and promoting targeted approaches to address specific SDG Indicators. Although several European projects in the Balkan transboundary river basin areas focus on existing/potential ties to specific SDG Indicators under the leadership of i-BEC, data are lacking for some regions, and there is an exigent need for country/region - specific case studies. A case study in Albania, the 3rd for CEOS and the 1st for Europe, will seek to build synergies between different sectors and activities (water, energy, food) and natural resources, while also accounting for ecosystem climate- regulating functions. This will contribute to the global expansion of the Data Cube initiative, while adding high quality datasets in GEOSS. Engagement of EO ecosystem stakeholders, together with National Statistical Offices, regionally and globally, should exploit the networking capacities of multipliers, maximizing the impact and reach of SSL.

    Three manifestations of the extreme amplification of the human population--exploding worldwide demand for energy, increasing exploitation of and competition for water resources, and alteration of the planet's climate--are tightly intertwined. All processes for generating energy require consumption of water, for some processes enormous quantities. It takes water to get energy. The inverse is also true: it takes energy to get water. It takes energy to move water from where it is stored to where it is needed. Burning fossil fuels for energy has increased greenhouse gasses in the atmosphere, resulting in increases in the average temperature of the Earth. But the response of the climate system is exceedingly complex. Changes in atmospheric circulation due to global warming are altering weather patterns and changing the distribution of water on the planet. Climate-related weather events alter availability of water and impact energy supply and demand. This is the nexus of energy, water, and climate. We have created two lively card games that convey the nexus concepts. They have been extensively play-tested with groups from middle school to adult; they have been found to be both educational and fun. A distinguished advisory committee, including representatives of the national labs, has insured the scientific accuracy of the games. In the first game, Thirst For Power, each player is the governor of a region; a GOAL card specifies the amount of General and Transportation energy needed for the region, achieved via ENERGY SOURCE cards. WATER cards are used as currency for obtaining energy sources. Each energy source has an associated 'environmental impact' penalty, meaning greenhouse gas emissions, but also other things like water and air pollution. ACTION cards (TECHNOLOGY, POLICY, AND CLIMATE) act much like 'Chance' cards in Monopoly to change the course of the game. The first player to achieve energy goals without exceeding an environmental impact limit for the region wins

    While thermoelectric power generation accounts for only 3-5% of the nation's consumptive use of freshwater, its future potential to exert pressure on limited water supplies is of concern given projected growth in electric power generation. The corresponding thermoelectric water footprint could look significantly different depending on decisions concerning the mix of fuel type, cooling type, location, and capacity, which are influenced by such factors as fuel costs, technology evolution, demand growth, policies, and climate change. The complex interplay among these disparate factors makes it difficult to identify where water could limit siting choices for thermoelectric generation or alternatively, thermoelectric development could limit growth in other water use sectors. These arguments point to the need for joint coordination, analysis and planning between energy and water managers. Here we report on results from a variety of planning exercises spanning scales from the national, interconnection, to the utility. Results will highlight: lessons learned from the integrated planning exercises; the broad range in potential thermoelectric water use futures; regional differences in the thermoelectric-water nexus; and, opportunities for non-traditional waters to ease competition over limited freshwater supplies and to harden thermoelectric generation against drought vulnerability.

    Many of the world's multi-reservoir water resource systems are being considered for further development of hydropower and irrigation aiming to meet economic, political and ecological goals. Complex river basins serve many needs so how should the different proposed groupings of reservoirs and their operations be evaluated? How should uncertainty about future supply and demand conditions be factored in? What reservoir designs can meet multiple goals and perform robustly in a context of global change? We propose an optimized multi-criteria screening approach to identify best performing designs, i.e., the selection, size and operating rules of new reservoirs within multi-reservoir systems in a context of deeply uncertain change. Reservoir release operating rules and storage sizes are optimized concurrently for each separate infrastructure design under consideration across many scenarios representing plausible future conditions. Outputs reveal system trade-offs using multi-dimensional scatter plots where each point represents an approximately Pareto-optimal design. The method is applied to proposed Blue Nile River reservoirs in Ethiopia, where trade-offs between capital costs, total and firm energy output, aggregate storage and downstream irrigation and energy provision for the best performing designs are evaluated. The impact of filling period for large reservoirs is considered in a context of hydrological uncertainty. The approach is also applied to the Koshi basin in Nepal where combinations of hydropower storage and run-of-river dams are being considered for investment. We show searching for investment portfolios that meet multiple objectives provides stakeholders with a rich view on the trade-offs inherent in the nexus and how different investment bundles perform differently under plausible futures. Both case-studies show how the proposed approach helps explore and understand the implications of investing in new dams in a global change context.

  6. New Insight into the Finance-Energy Nexus: Disaggregated Evidence from Turkish Sectors

    2017-01-01

    Full Text Available Seeing that reshaped energy economics literature has adopted some new variables in energy demand function, the number of papers looking into the relationship between financial development and energy consumption at the aggregate level has been increasing over the last few years. This paper, however, proposes a new framework using disaggregated data and investigates the nexus between financial development and sectoral energy consumption in Turkey. To this end, panel time series regression and causality techniques are adopted over the period 1989–2011. Empirical results confirm that financial development does have a significant impact on energy consumption, even with disaggregated data. It is also proved that the magnitude of financial development is larger in energy-intensive industries than in less energy-intensive ones.

    Highlights: • Developed a CMDP model for the energy–water–climate change nexus. • Solved the model using a reinforcement learning algorithm. • Study demonstrated on 30-bus IEEE electric power network using DCOPF formulation. • Sixty percentage drop in CO 2 and 40% drop in H 2 O use when coal replaced by wind (over 10 years). • Higher profits for nuclear and wind as well as higher LMPs under CO 2 and H 2 O taxes. - Abstract: Drought-like conditions in some parts of the US and around the world are causing water shortages that lead to power failures, becoming a source of concern to independent system operators. Water shortages can cause significant challenges in electricity production and thereby a direct socioeconomic impact on the surrounding region. Our paper presents a new, comprehensive quantitative model that examines the electricity–water–climate change nexus. We investigate the impact of a joint water and carbon tax proposal on the operation of a transmission-constrained power network operating in a wholesale power market setting. We develop a competitive Markov decision process (CMDP) model for the dynamic competition in wholesale electricity markets, and solve the model using reinforcement learning. Several cases, including the impact of different tax schemes, integration of stochastic wind energy resources, and capacity disruptions due to droughts are investigated. Results from the analysis on the sample power network show that electricity prices increased with the adoption of water and carbon taxes compared with locational marginal prices without taxes. As expected, wind energy integration reduced both CO 2 emissions and water usage. Capacity disruptions also caused locational marginal prices to increase. Other detailed analyses and results obtained using a 30-bus IEEE network are discussed in detail

    2018-03-01

    Full Text Available This paper analyses the cross-sectoral integration of the water-energy nexus in Brazil. Recent droughts resulted in unprecedented water scarcity. This caused water shortages for population and agriculture, as well as for electricity production (hydropower being the main source of electricity production. As a result, the system became more vulnerable to blackouts. To alleviate the problem, fossil fuels were used as a back up. Droughts, floods and other water-related problems will not dissipate as time goes by in Brazil. The dependency on one single predominant source (hydropower makes Brazil’s electricity supply vulnerable. This study shows through data analysis, flow diagrams and metrics the interrelation between water and energy. Based on historical data, the analysis shows the importance of the water demand for hydropower, cooling for thermal plants, and the extraction and production of biofuels, as well as of the energy demand of water services (water supply, wastewater treatment.

    This paper reviews the nexus between poverty and HIV/AIDS in Africa using a sustainable livelihood framework. Much of the literature on HIV and AIDS has generated an almost universal consensus that the AIDS epidemic is having an immense impact on the economies of hard-hit countries, hurting not only individuals, families and firms, but also significantly slowing economic growth and worsening poverty. International evidence has concentrated on the pathways through which HIV/AIDS undermines livelihoods and raises vulnerability to future collapse of livelihoods. Yet, little attention has been paid to the role that social relations and livelihood strategies can play in bringing about risky social interaction that raises the chance of contracting HIV. Using the sustainable livelihood and social relation approaches, this article demonstrates that although AIDS is not simply a disease of the poor, determinants of the epidemic go far beyond individual volition and that some dimensions of being poor increase risk and vulnerability to HIV.

    Tropical forests are undergoing land use change in many regions of the world, including the African continent. Human populations living close to forest margins fragmented and disturbed by deforestation may be particularly exposed to zoonotic infections because of the higher likelihood for humans to be in contact with disease reservoirs. Quantitative analysis of the nexus between deforestation and the emergence of Ebola virus disease (EVD), however, is still missing. Here we use land cover change data in conjunction with EVD outbreak records to investigate the association between recent (2004-2014) outbreaks in West and Central Africa, and patterns of land use change in the region. We show how in these EVD outbreaks the index cases in humans (i.e. spillover from wildlife reservoirs) occurred mostly in hotspots of forest fragmentation.

    Often quantitative scenarios of future trends exhibit less variability than the historic data upon which the models that generate them are based. The problem of dampened variability, which typically also entails dampened extremes, manifests both temporally and spatially. As a result, risk assessments that rely on such scenarios are in danger of producing misleading results. This danger is pronounced in nexus issues, because of the multiple dimensions of change that are relevant. We illustrate the above problem by developing alternative joint distributions of the probability of drought and of human population totals, across U.S. counties over the period 2010-2030. For the dampened-extremes case we use drought frequencies derived from climate models used in the U.S. National Climate Assessment and the Environmental Protection Agency's population and land use projections contained in its Integrated Climate and Land Use Scenarios (ICLUS). For the elevated extremes case we use an alternative spatial drought frequency estimate based on tree-ring data, covering a 555-year period (Ho et al 2017); and we introduce greater temporal and spatial extremes in the ICLUS socioeconomic projections so that they conform to observed extremes in the historical U.S. spatial census data 1790-present (National Historical Geographic Information System). We use spatial and temporal coincidence of high population and extreme drought as a proxy for energy-water nexus risk. We compare the representation of risk in the dampened-extreme and elevated-extreme scenario analysis. We identify areas of the country where using more realistic portrayals of extremes makes the biggest difference in estimate risk and suggest implications for future risk assessments.

    Water-Energy-Land (WEL) Nexus management is one of those complex decision problems where holistic approach to supply-demand management considering different criteria would be valuable. However, multi-criteria decision making with diverse indicators measured on different scales and uncertainty levels is difficult to solve. On the other hand, climate adaptation and mitigation need to be integrated, and resource sensitive regions like Mediterranean provide ample opportunities towards that end. While the water sector plays a key role in climate adaptation, mitigation focuses on the energy and agriculture sector. Recent studies on the so-called WEL nexus confirm the potential synergies to be derived from mainstreaming climate adaptation in the water sector, while simultaneously addressing opportunities for co-management with energy (and also land use). Objective of this paper is to develop scenarios for the future imbalances in water & energy supply and demand for a water stressed Mediterranean area of Northern Spain (Catalonia) and to test the scenario based climate adaptation & mitigation strategy for WEL management policies. Resource sensitive area of Catalonia presents an interesting nexus problem to study highly stressed water demand scenario (representing all major demand sectors), very heterogeneous land use including intensive agriculture to diversified urban and industrial uses, and mixed energy supply including hydro, wind, gas turbine to nuclear energy. Different energy sectors have different water and land requirements. Inter-river basin water transfer is another factor which is considered for this area. The water-energy link is multifaceted. Energy production can affect water quality, while energy is used in water treatment and to reduce pollution. Similarly, hydropower - producing energy from water - and desalination - producing freshwater using energy - both play important role in economic growth by supplying large and secure amounts of 'green' energy or

    New renewable energy policies, investment opportunities, and energy security needs, have recently led to an escalation in the reliance on first generation biofuels. This phenomenon is contributing to changes in land use, market dynamics, property rights, and systems of agricultural production, with important impacts on rural livelihoods. Despite these effects of biofuels on food security, their nexus with land and water use remains poorly understood. We investigate recent production trends of bioenergy crops, their patterns of trade, and evaluate the associated displacement of water and land use. We find that bioethanol is produced with domestic crops while biodiesel production relies also on international trade and large scale land acquisitions in the developing world, particularly in Southeast Asia. Altogether, biofuels account for about 2-3% of the global water and land use in agriculture, and 30% of the food required to eradicate malnourishment worldwide. We evaluate the food-energy tradeoffs of biofuels and their impact of the number of people the plant can feed.

    Full Text Available This paper empirically tests several hypotheses about the nexus of corruption-institutional trust in Post-Soviet transitional countries of the former Soviet Union and Mongolia. We use two different indices of institutional trust to check the robustness of our analysis and estimate OLS and instrumental variable models with and without interaction terms. All things considered, our findings reject “greases the wheels” and “trust begets an honest political system” hypotheses. Instead, our findings support the “sand the wheels” hypothesis. Furthermore, a multiplicative interaction model suggests that the negative marginal effects of experienced corruption are higher in the environments where satisfaction with services is low. In addition, we found that increases in corruption erode trust at all levels of the societal institutions including political parties, government and financial institutions, international investors, non-profit organizations, and trade unions. This finding is important since it highlights the negative consequences of corruption on the development of broader level economic institutions and on civil society.

    While agriculture places the greatest demand on water resources, increasing agricultural production is worsening a global water shortage. Reducing the cultivation of water-consuming crops may be the most effective way to reduce agricultural water use. However, when also taking food demand into consideration, sustaining the balance between regional water and food securities is a growing challenge. This paper addresses this task for regions where water is unsustainable for food production (Beijing-Tianjin-Hebei Region for example) by: (i) assessing the different effects of wheat and maize on water use; (ii) analyzing virtual water and virtual land flows associated with food imports and exports between Beijing-Tianjin-Hebei and elsewhere in China; (iii) identifying sub-regions where grain is produced using scarce water resources but exported to other regions; and (iv) analyzing the potentiality for mitigating water shortage via Land-Water-Food Nexus. In the Beijing-Tianjin-Hebei Region, the study reveals that 29.76 bn m 3 of virtual water (10.81 bn m 3 of blue virtual water) are used by wheat and maize production and 8.77 bn m 3 of virtual water used in nearly 2 million ha of cropland to overproduce 12 million ton of maize for external food consumption. As an importing-based sub-region with high population density, Beijing & Tianjin imported mostly grain (wheat and maize) from Shandong Province. Then, Hebei Province, as an exporting-based sub-region with severe water shortage, overproduced too much grain for other regions, which aggravated the water crisis. To achieve an integrated and sustainable development of the Beijing-Tianjin-Hebei Region, Hebei Province should stop undertaking the breadbasket role for Beijing & Tianjin and pay more attention to groundwater depletion. The analysis of the Land-Water-Food Nexus indicates how shifts in cultivated crops can potentially solve the overuse of water resources without adverse effects on food supply

As an importing-based sub-region with high population density, Beijing and Tianjin (BT) imported mostly grain (wheat and maize) from Shandong (SD). Whereas, Hebei (HB), as an exporting-based sub-region with sever water shortage, overproduced too much grain for other regions (like Central area), which aggravated water crisis. To achieve Beijing-Tianjin-Hebei's integrated and sustainable development, HB should not undertake the breadbasket role for BT but pay more attention to groundwater depletion.

    Based on the modeling of the water supply, power generation and environment (WPE) nexus by Feng et al. (2016), a refined theoretical model of competitive water consumption between human society and environment has been presented in this study, examining the role of technology advancement and social environmental awareness growth-induced pollution mitigation to the environment as a mechanism for the establishment and maintenance of the coexistence of both higher social water consumption and improved environment condition. By coupling environmental and social dynamics, both of which are represented by water consumption quantity, this study shows the possibility of sustainable situation of the social-environmental system when the benefit of technology offsets the side effect (pollution) of social development to the environment. Additionally, regime shifts could be triggered by gradually increased pollution rate, climate change-induced natural resources reduction and breakdown of the social environmental awareness. Therefore, in order to foresee the pending abrupt regime shifts of the system, early warning signals, including increasing variance and autocorrelation, have been examined when the system is undergoing stochastic disturbance.

  1. More Energy and Less Work, but New Crises: How the Societal Metabolism-Labour Nexus Changes from Agrarian to Industrial Societies

    2017-06-01

    Full Text Available The scientific finding that humanity is overburdening nature and thus risks further ecological crises is almost uncontroversial. Main reason for the crises is the drastic increase in the societal metabolism, which is accomplished through labour. In this article, we examine the societal metabolism-labour nexus in two energy regimes: a valley in the Ethiopian highlands, typical of an agrarian society, and a village in Austria, typical of an industrial society. In the Ethiopian village, the supply of food demands almost the entire labour force, thus limiting the capacity to facilitate material flows beyond food provision. In the Austrian village, fewer working hours, lower workloads but 50 times higher useful energy allow to accumulate stocks like buildings 70 times higher than the Ethiopian case. With fossil energy, industrial societies decisively expand their energy supply and reduce labour hours at the cost of high carbon emissions, which are almost non-existent in the Ethiopian case. To overcome the resulting ecological crises, there is a call to drastically reduce fossil fuel consumption. Such an abandonment of fossil fuels might have as far reaching consequences for the societal metabolism-labour nexus and consequently human labour as the introduction of fossil fuels has had.

    The Indonesian archipelago is prone to various geological hazards on an almost day to day basis. In order to mitigate disaster risk and reduce losses, the government uses its unique setup of ministerial training institutions. The Centre for Development of Human Resources in Geology, Mineral and Coal offers different level of technical training to local governments in order to provide them with the necessary means to understand geological hazards, mitigate risks, and hence close the gap between local and national governments. One key factor has been the continuous incorporation of new scientific knowledge into their training curricula. The paper presents benefits and challenges of this science-practice nexus using the standardised landslide survey as one example where mobile technology has been introduced to the training just recently.

    2010-06-01

    In this article, we argue that a combined anthropology/neuroscience field of enquiry can make a significant and distinctive contribution to the study of the relationship between culture and the brain. This field, which can appropriately be termed as neuroanthropology, is conceived of as being complementary to and mutually informative with social and cultural neuroscience. We start by providing an introduction to the culture concept in anthropology. We then present a detailed characterization of neuroanthropology and its methods and how they relate to the anthropological understanding of culture. The field is described as a humanistic science, that is, a field of enquiry founded on the perceived epistemological and methodological interdependence of science and the humanities. We also provide examples that illustrate the proposed methodological model for neuroanthropology. We conclude with a discussion about specific contributions the field can make to the study of the culture-brain nexus.

  4. An Agent-based Modeling of Water-Food Nexus towards Sustainable Management of Urban Water Resources

    2017-12-01

    Growing population, urbanization, and climate change have put tremendous stress on water systems in many regions. A shortage in water system not only affects water users of a municipality but also that of food system. About 70% of global water is withdrawn for agriculture; livestock and dairy productions are also dependent on water availability. Although researchers and policy makers have identified and emphasized the water-food (WF) nexus in recent decade, most existing WF models offer strategies to reduce trade-offs and to generate benefits without considering feedback loops and adaptations between those systems. Feedback loops between water and food system can help understand long-term behavioral trends between water users of the integrated WF system which, in turn, can help manage water resources sustainably. An Agent-based modeling approach is applied here to develop a conceptual framework of WF systems. All water users in this system are modeled as agents, who are capable of making decisions and can adapt new behavior based on inputs from other agents in a shared environment through a set of logical and mathematical rules. Residential and commercial/industrial consumers are represented as municipal agents; crop, livestock, and dairy farmers are represented as food agents; and water management officials are represented as policy agent. During the period of water shortage, policy agent will propose/impose various water conservation measures, such as adapting water-efficient technologies, banning outdoor irrigation, implementing supplemental irrigation, using recycled water for livestock/dairy production, among others. Municipal and food agents may adapt conservation strategies and will update their demand accordingly. Emergent properties of the WF nexus will arise through dynamic interactions between various actors of water and food system. This model will be implemented to a case study for resource allocation and future policy development.

  5. Immunity and Impunity: Corruption in the State-Pharma Nexus

    Directory of Open Access Journals (Sweden)

    Paddy Rawlinson

    2017-11-01

    Full Text Available Critical criminology repeatedly has drawn attention to the state-corporate nexus as a site of corruption and other forms of criminality, a scenario exacerbated by the intensification of neoliberalism in areas such as health. The state-pharmaceutical relationship, which increasingly influences health policy, is no exception. That is especially so when pharmaceutical products such as vaccines, a burgeoning sector of the industry, are mandated in direct violation of the principle of informed consent. Such policies have provoked suspicion and dissent as critics question the integrity of the state-pharma alliance and its impact on vaccine safety. However, rather than encouraging open debate, draconian modes of governance have been implemented to repress and silence any form of criticism, thereby protecting the activities of the state and pharmaceutical industry from independent scrutiny. The article examines this relationship in the context of recent legislation in Australia to intensify its mandatory regime around vaccines. It argues that attempts to undermine freedom of speech, and to systematically excoriate those who criticise or dissent from mandatory vaccine programs, function as a corrupting process and, by extension, serve to provoke the notion that corruption does indeed exist within the state-pharma alliance.

    UMd-PERG's NEXUS/Physics for Life Sciences laboratory curriculum, piloted in 2012-2013 in small test classes, has been implemented in large-enrollment environments at UMD from 2013-present. These labs address physical issues at biological scales using microscopy, image and video analysis, electrophoresis, and spectroscopy in an open, non-protocol-driven environment. We have collected a wealth of data (surveys, video analysis, etc.) that enables us to get a sense of the students' responses to this curriculum in a large-enrollment environment and with teaching assistants both `new to' and `experienced in' the labs. In this talk, we will provide a brief overview of what we have learned, including the challenges of transitioning to large N, student perception then and now, and comparisons of our large-enrollment results to the results from our pilot study. We will close with a discussion of the acculturation of teaching assistants to this novel environment and suggestions for sustainability.

    Water, Food and energy systems are highly interconnected. More than seventy percent of global water resource is used for food production. Water withdrawal, purification, and transfer systems are energy intensive. Furthermore, energy generation strongly depends on water availability. Therefore, considering the interactions in the nexus of water, food and energy is crucial for sustainable management of available resources. In this presentation, we introduce a user-friendly data analysis toolbox that mines the available global data on food, energy and water, and analyzes their interactions. This toolbox provides estimates of water footprint for a wide range of food types in different countries and also approximates the required energy and water resources. The toolbox also provides estimates of the corresponding emissions and biofuel production of different crops. In summary, this toolbox allows evaluating dependencies of the food, energy, and water systems at the country scale. We present global analysis of the interactions between water, food and energy from different perspectives including efficiency and diversity of resources use.

    The articles in this special issue examine the critical nexus of electricity, water, and climate, emphasizing connections among resources;  the prospect of increasing vulnerabilities of water resources and electricity generation in a changing climate;  and the opportunities for research to inform integrated energy and water policy and management measures aimed at reducing vulnerability and increasing resilience. Here, we characterize several major themes emerging from this research and highlight some of the uptake of this work in both scientific and public spheres.  Underpinning much of this research is the recognition that water resources are expected to undergo substantial changes based on the global warming that results primarily from fossil energy-based carbon emissions.  At the same time, the production of electricity from fossil fuels, nuclear power, and some renewable technologies (biomass, geothermal and concentrating solar power) can be highly water-intensive.  Energy choices now and in the near future will have a major impact not just on the global climate, but also on water supplies and the resilience of energy systems that currently depend heavily on them.

    Raised-bed plasticulture, an intensive production system used around the world for growing high-value crops (e.g., fresh market vegetables), faces a water-food nexus that is actually a food-water-energy-land-economic nexus. Plasticulture represents a multibillion dollar facet of the United States crop production value annually and must become more efficient to be able to produce more on less land, reduce water demands, decrease impacts on surrounding environments, and be economically-competitive. Taller and narrower futuristic beds were designed with the goal of making plasticulture more sustainable by reducing input requirements and associated wastes (e.g., water, nutrients, pesticides, costs, plastics, energy), facilitating usage of modern technologies (e.g., drip-based fumigation), improving adaptability to a changing climate (e.g., flood protection), and increasing yield per unit area. Compact low-input beds were analyzed against conventional beds for the plasticulture production of tomato (Solanum lycopersicum), an economically-important crop, using a systems approach involving field measurements, vadose-zone modeling (HYDRUS), and production analysis. Three compact bed geometries, 61 cm (width) × 25 cm (height), 45 cm × 30 cm, 41 cm × 30 cm, were designed and evaluated against a conventional 76 cm × 20 cm bed. A two-season field study was conducted for tomato in the ecologically-sensitive and productive Everglades region of Florida. Compact beds did not statistically impact yield and were found to reduce: 1) production costs by 150-450/ha; 2) leaching losses by up to 5% (1 cm/ha water, 0.33 kg/ha total nitrogen, 0.05 kg/ha total phosphorus); 3) fumigant by up to 47% (48 kg/ha); 4) plasticulture's carbon footprint by up to 10% (1711 kg CO2-eq/ha) and plastic waste stream by up to 13% (27 kg/ha); 5) flood risks and disease pressure by increasing field's soil water storage capacity by up to 33% (≈1 cm); and 6) field runoff by 0.48-1.40 cm (51-76%) based on

    Florida is a hotspot of endemism for plants, vertebrates, and insects outside of the tropics. The state has extensive coastline, with the maximum distance from the coast less than 150 km which has diverse ecosystems and landscapes, as well as habitat for many endangered species. Additionally, agriculture is one of the most important economic resources in Florida and is ranked second in the U.S. for value of vegetable production. Florida's biodiversity is threatened by stressors such as increasing urbanization and population, land-use change and socio-economic growth. Given that, climate change and variability will interact with these stresses, potentially accentuating their negative impacts, there are several studies, concerning climate change impacts on Florida's ecosystem to date. The specific objectives of this study were to demonstrate the decision support tool developed from meta-analysis. The Tool was developed using the temperature and precipitation changes in Florida identified from peer reviewed studies. These change values were then synthesized using simple statistical techniques (e.g., histogram, line plots and density plots). Our results indicate a wide variability in the temperature and precipitation changes observed in the studies for Florida. The studies showed a temperature change ranged between +5 °C and -3 °C, while the precipitation change ranged between +30% and -40% in the state. These changes have series implications on the food-water-energy nexus. Some of the potential implications of these changes in the context of the nexus are discussed using causal chains developed from meta-analysis.

    Full Text Available The export and economic growth nexus, which is called Balassa’s Export-Led Growth Hypothesis (ELGH  in the literature, is still an unstill issue in both the theoretical and empirical literature. In the present study, the effect of export on economic growth in  oil exporting developing countries, namely, Bahrain, Saudi Arabia, Qatar,  Kuwait, UAE, and Oman in the 1990–2014 period was tested based on three models, pooled ordinary least squares (POLS, fixed effects model (FEM, and random effects model (REM  via panel data analysis . The findings revealed strong support for the “export-led growth” hypothesis. In addition, our results show that apart from growth in the labor force, investments in capital formation are necessary for economic growth. According to the obtained results, the ability to adopt technological changes in order to increase efficiency, and sustain economic development is also important.

    Full Text Available This article aims at exploring the nexus between the fundamental rights to life and to a basic education within the ambit of the legal framework created by both the Constitution of the Republic of South Africa, 1996 and the South African Schools Act 84 of 1996. Attention is drawn to the role of the law to order the living world humans live in an thus creating an emancipated framework allowing individuals a moral and self-sufficient life.The overarching goal of the supreme Constitution is to improve the quality of life of all citizens and ultimately to free everyone’s potential. In order to reach this goal and allow everyone to live a dignified life that it is worth living, the importance of education is highlighted. As important source of education law, the objectives of the Schools Act, namely to (a provide education of a progressively high quality, (b lay a strong foundation for the development of humans’ talents and capabilities, (c advance democratic transformation, (d combat discrimination and intolerance, (e assist the eradication of poverty and the well-being of society, (f uphold learner rights and (g promote the acceptance of responsibility are discussed and their practical realisation scrutinised. This lead to the author to establish the nexus between the two fundamental rights and to delineate the prominence of the delivering of a progressively high quality of education is provided to all South Africans to enhance their quality of life. By taking regard of the role of the law in the sphere of education, the duties placed on all educational role-players to take responsibility for the delivery of educational services and be accountable therefore, are highlighted. The value of education was in this regard stressed in order to enable humans to take responsibility for their own lives, the conditions under which they live, the choices they make and the changes they bring about to better their lives.

  13. A Water–Energy–Food Nexus Perspective on the Challenge of Eutrophication

    Directory of Open Access Journals (Sweden)

    V. Ratna Reddy

    2018-01-01

    Full Text Available This paper attempts to understand and explore the problem of eutrophication in the context of agriculture with the help of a nexus perspective. Eutrophication is significantly linked to water and energy resources with theoretically well-defined trade-offs and threshold levels. While looking at the linkages between water and land resources comprehensively, our paper questions the present approach to designing and implementing watershed management, and analyses the effects of agricultural intensification, especially in dry regions. Eutrophication is the process by which excessive nutrient loads in water bodies lead to undesirable water-quality problems and the degradation of the overall aquatic ecosystem. Due to limited information and knowledge on water and soil quality in most countries, farmers continue to use fertilizers at an increasing rate and agricultural run-off has been carrying ever more nitrogen and phosphorus into water bodies. This is likely to become a vicious cycle of eutrophication affecting food and water security. Of late, soil- and water-conservation interventions, like watershed development, are further reducing run-off. It is argued that there is a need to rethink the assumptions under which watershed interventions are designed and implemented.

    Full Text Available The water footprint of energy systems must be considered, as future water scarcity has been identified as a major concern. This work presents a general life cycle network modeling and optimization framework for energy-based products and processes using a functional unit of liters of water consumed in the processing pathway. We analyze and optimize the water-energy nexus over the objectives of water footprint minimization, maximization of economic output per liter of water consumed (economic efficiency of water, and maximization of energy output per liter of water consumed (energy efficiency of water. A mixed integer, multiobjective nonlinear fractional programming (MINLFP model is formulated. A mixed integer linear programing (MILP-based branch and refine algorithm that incorporates both the parametric algorithm and nonlinear programming (NLP subproblems is developed to boost solving efficiency. A case study in bioenergy is presented, and the water footprint is considered from biomass cultivation to biofuel production, providing a novel perspective into the consumption of water throughout the value chain. The case study, optimized successively over the three aforementioned objectives, utilizes a variety of candidate biomass feedstocks to meet primary fuel products demand (ethanol, diesel, and gasoline. A minimum water footprint of 55.1 ML/year was found, economic efficiencies of water range from −$1.31/L to $0.76/L, and energy efficiencies of water ranged from 15.32 MJ/L to 27.98 MJ/L. These results show optimization provides avenues for process improvement, as reported values for the energy efficiency of bioethanol range from 0.62 MJ/L to 3.18 MJ/L. Furthermore, the proposed solution approach was shown to be an order of magnitude more efficient than directly solving the original MINLFP problem with general purpose solvers.

    2018-01-01

    To improve predictions of ecosystem function in future environments, we need to integrate the ecological and environmental histories experienced by microbial communities with hydrobiogeochemistry across scales. A key issue is whether we can derive generalizable scaling relationships that describe this multiscale integration. There is a strong foundation for addressing these challenges. We have the ability to infer ecological history with null models and reveal impacts of environmental history through laboratory and field experimentation. Recent developments also provide opportunities to inform ecosystem models with targeted omics data. A major next step is coupling knowledge derived from such studies with multiscale modeling frameworks that are predictive under non-steady-state conditions. This is particularly true for systems spanning dynamic interfaces, which are often hot spots of hydrobiogeochemical function. We can advance predictive capabilities through a holistic perspective focused on the nexus of history, ecology, and hydrobiogeochemistry.

    The main focus of this paper is to estimate the effects of foreign direct investment (FDI) inflows, income and energy consumption on CO_2 emissions using panel data of five ASEAN countries over 1981–2010. The results based on the pooled mean group (PMG) estimator of dynamic panels show that FDI tends to increase CO_2 emissions, supporting evidence of the pollution haven hypothesis. We also find that income and energy consumption have a detrimental impact on reducing CO_2 emissions. - Highlights: • This study examines the FDI–income–energy–environment nexus. • The pooled mean group (PMG) estimator is applied to panel data of 5 ASEAN countries. • FDI deteriorates the environment, supporting the pollution haven hypothesis. • Growth and energy consumption have a detrimental effect on the environment.

    2013-11-01

    Despite its ongoing federal illegality, marijuana production has become a licit, or socially accepted, feature of northern California's real estate market. As such, marijuana is a key component of land values and the laundering of "illegal" wealth into legitimate circulation. By following land transaction practices, relations, and instruments, this article shows how formally equal property transactions become substantively unequal in light of the "il/legal" dynamics of marijuana land use. As marijuana becomes licit, prohibitionist policies have enabled the capture of ground rent by landed interests from the marijuana industry at a time when the price of marijuana is declining (in part due to its increasing licitness). The resulting "drug war rentier nexus," a state-land-finance complex, is becoming a key, if obscured, component within marijuana's contemporary political economy.

    2012-01-01

    At the end of 2010, China's contribution to global CO 2 emissions reached 25.1%. Estimates show that power generation accounts for 37.2% of the Chinese CO 2 emissions. Even though there is an increasing number of studies using life cycle analysis (LCA) to examine energy consumption and CO 2 emissions required by different types of power generation technologies, there are very few studies focusing on China. Furthermore, the nexus between water consumption and energy production has largely been ignored. In this paper, we adopt input–output based hybrid life cycle analysis to evaluate water consumption and CO 2 emissions of wind power in China. Our results show that China's wind energy consumes 0.64 l/kWh of water and produces 69.9 g/kWh of CO 2 emission. Given that the Chinese government aims to increase the wind power generation capacity to 200 GW by 2020, wind power could contribute a 23% reduction in carbon intensity and could save 800 million m 3 of water which could be sufficient enough for use by 11.2 million households. Thus, given the often postulated water crisis, China's energy policy would reap double benefits through progressive energy policies when increasing the share of wind power as part of overall efforts to diversify its electricity generation technologies. - Highlights: ► The nexus of water consumption and CO 2 emission of China's wind power is examined. ► Wind power consumes 0.64 l/kWh of water and produces 69.9 g/kWh of CO 2 . ► Wind power could save 800 million m 3 of water for use by 11.2 million households. ► Wind power could contribute 23% of China's carbon intensity target by 2020. ► Wind power deemed to be a viable means of achieving carbon and water savings.

  1. The Energy-GDP Nexus. Addressing an old question with new methods

    Coers, R.J.; Sanders, M.

    2012-01-15

    This paper reassesses the causal relationship between per capita energy use and gross domestic product, while controlling for capital and labour (productivity) inputs in a panel of 30 OECD countries over the past 40 years. The paper uses panel unit root and cointegration testing and specifies an appropriate vector error correction model to analyse the nexus between income and energy use. In doing so we contribute to an old debate using modern tools that shed a new light. There is some evidence that over the short-run bidirectional causality exists. Our results also show a strong unidirectional causality running from capital formation and GDP to energy usage. In the long run the reverse causality, found in recent work, is lost. We then show that we can reproduce these earlier results in our data if we reproduce a slightly misspecified model for the Engle-Granger two-step procedure used in these earlier papers. Our findings thus imply that results are very sensitive to model misspecification and careful testing of specifications is required. Our results have some strong policy implications. They suggest that policies aimed at reducing energy usage or promoting energy efficiency are not likely to have a detrimental effect on economic growth, except over the very short run.

    Studies that have investigated the role of unemployment in childbearing decisions have often shown no or only barely significant results. We argue that many of these "non-findings" may be attributed to a neglect of group-specific differences in behavior. In this study, we examine how the association of unemployment and fertility varies by socio-demographic subgroups using data from the German Socio-Economic Panel (GSOEP) and from Danish population registers. We find that male unemployment is related to a postponement of first and second childbearing in both countries. The role of female unemployment is less clear at these two parities. Both male and female unemployment is positively correlated with third birth risks. More importantly, our results show that there are strong educational gradients in the unemployment and fertility nexus, and that the relationship between unemployment and fertility varies by socioeconomic group. Fertility tends to be lower during periods of unemployment among highly educated women and men, but not among their less educated counterparts. Copyright © 2014 The Authors.

    2016-01-01

    Full Text Available The challenge of feeding nine billion people by 2050, in a context of constrained resources and growing environmental pressures posed by current food production methods on one side, and changing lifestyles and consequent shifts in dietary patterns on the other, exacerbated by the effects of climate change, has been defined as one of the biggest challenges of the 21st century. The first step to achieve food security is to find a balance between the growing demand for food, and the limited production capacity. In order to do this three main pathways have been identified: employing sustainable production methods in agriculture, changing diets, and reducing waste in all stages of the food chain. The application of an energy, water and food nexus (EWFN approach, which takes into account the interactions and connections between these three resources, and the synergies and trade-offs that arise from the way they are managed, is a prerequisite for the correct application of these pathways. This work discusses how Life Cycle Assessment (LCA might be applicable for creating the evidence-base to foster such desired shifts in food production and consumption patterns.

    Full Text Available Commonly, international human migration is blamed for corroding states sovereignty, especially stemming from policy circles, academic literature and citizens of the host countries. This has attracted the attention of the media highlighting hazards of being a migrant, with some countries viewing migrants as enemies; and, Cuba provides a vivid case. Yet in other countries, migrants are viewed as important contributors to social and economic development, with Mexico, the Dominican Republic and India serving as examples. This article locates migrants in the framework of human rights as guided by international law without prejudice to the demands of state sovereignty, but linking the two in the context of developing international standards. Migration is seen as a feature of human history dating back to primordial time. Nothing appears surprising in the movement of people across borders, defining a migrant through emigration and immigration while giving due respect to the sovereignty of states, both sending and receiving. The article discusses the nexus between migrants and state sovereignty in order to highlight the mutual benefit grounded in international law. It attempts to portray a more positive image of the migrant person in light of the global world, socio-economic development and human rights fundamentals. The main challenge remains that of implementing human rights, which appear to be at the crossroads of individual rights and state sovereignty. The paper reveals how the challenge can be overcome while maintaining the structure of rights and freedoms without infringement on states’ sovereignty. It concludes that migrants remain on the periphery of effective protection from the vagaries of the citizens, partly because the state has a tendency to confine certain rights to its citizenry. States possess discretionary authority to control the ingress of foreign nationals into their territories though sometimes they fail to do that as evidenced

    Resource management policies are frequently designed and planned to target specific needs of particular sectors, without taking into account the interests of other sectors who share the same resources. In a climate of resource depletion, population growth, increase in energy demand and climate change awareness, it is of great importance to promote the assessment of intersectoral linkages and, by doing so, understand their effects and implications. This need is further augmented when common use of resources might not be solely relevant at national level, but also when the distribution of resources spans over different nations. This paper focuses on the study of the energy systems of five south eastern European countries, which share the Sava River Basin (SRB), using a water-food(agriculture)-energy nexus approach. In the case of the electricity generation sector, the use of water is essential for the integrity of the energy systems, as the electricity production in the riparian countries relies on two major technology types dependent on water resources: hydro and thermal power plants. For example, in 2012, an average of 37% of the electricity production in the SRB countries was generated by hydropower and 61% in thermal power plants. Focusing on the SRB, in terms of existing installed capacities, the basin accommodates close to a tenth of all hydropower capacity while providing water for cooling to 42% of the net capacity of thermal power currently in operation in the basin. This energy-oriented nexus study explores the dependency on the basin's water resources of the energy systems in the region for the period between 2015 and 2030. To do so, a multi-country electricity model was developed to provide a quantification ground to the analysis, using the open-source software modelling tool OSeMOSYS. Three main areas are subject to analysis: first, the impact of energy efficiency and renewable energy strategies in the electricity generation mix; secondly, the potential

    In land systems, equitably managing trade-offs between planetary boundaries and human development needs represents a grand challenge in sustainability oriented initiatives. Informing such initiatives requires knowledge about the nexus between land use, poverty, and environment. This paper presents results from Lao PDR, where we combined nationwide spatial data on land use types and the environmental state of landscapes with village-level poverty indicators. Our analysis reveals two general but contrasting trends. First, landscapes with paddy or permanent agriculture allow a greater number of people to live in less poverty but come at the price of a decrease in natural vegetation cover. Second, people practising extensive swidden agriculture and living in intact environments are often better off than people in degraded paddy or permanent agriculture. As poverty rates within different landscape types vary more than between landscape types, we cannot stipulate a land use–poverty–environment nexus. However, the distinct spatial patterns or configurations of these rates point to other important factors at play. Drawing on ethnicity as a proximate factor for endogenous development potentials and accessibility as a proximate factor for external influences, we further explore these linkages. Ethnicity is strongly related to poverty in all land use types almost independently of accessibility, implying that social distance outweighs geographic or physical distance. In turn, accessibility, almost a precondition for poverty alleviation, is mainly beneficial to ethnic majority groups and people living in paddy or permanent agriculture. These groups are able to translate improved accessibility into poverty alleviation. Our results show that the concurrence of external influences with local—highly contextual—development potentials is key to shaping outcomes of the land use–poverty–environment nexus. By addressing such leverage points, these findings help guide more

    Interactions between food demand, biomass energy and forest preservation are driving both food prices and land-use changes, regionally and globally. This study presents a new model called Nexus Land-Use version 1.0 which describes these interactions through a generic representation of agricultural intensification mechanisms within agricultural lands. The Nexus Land-Use model equations combine biophysics and economics into a single coherent framework to calculate crop yields, food prices, and resulting pasture and cropland areas within 12 regions inter-connected with each other by international trade. The representation of cropland and livestock production systems in each region relies on three components: (i) a biomass production function derived from the crop yield response function to inputs such as industrial fertilisers; (ii) a detailed representation of the livestock production system subdivided into an intensive and an extensive component, and (iii) a spatially explicit distribution of potential (maximal) crop yields prescribed from the Lund-Postdam-Jena global vegetation model for managed Land (LPJmL). The economic principles governing decisions about land-use and intensification are adapted from the Ricardian rent theory, assuming cost minimisation for farmers. In contrast to the other land-use models linking economy and biophysics, crops are aggregated as a representative product in calories and intensification for the representative crop is a non-linear function of chemical inputs. The model equations and parameter values are first described in details. Then, idealised scenarios exploring the impact of forest preservation policies or rising energy price on agricultural intensification are described, and their impacts on pasture and cropland areas are investigated.

    Full Text Available This paper examines the nexus of intelligence education and training from a South African perspective with the focus on current practices in light of the country’s transition towards democracy. A brief overview is provided on the history and development of the South African intelligence community with specific focus on the civilian intelligence services from the period prior 1994 to date (2015. The main focus, however, is on intelligence education that is currently available from training institutions and universities in South Africa as registered with the Department of Higher Education as well as private training institutions on the one hand, and the intelligence training practices within the statutory intelligence environment on the other. To this extent, the relations between academic institutions and the intelligence structures in terms of education and training within South Africa are perused against other practices within the African continent and internationally. The approaches to the study of intelligence are also addressed within this paper. Likewise, the how, what as well as to whom – pertaining to intelligence education and training availability and accessibility to students and practitioners within South Africa, is reviewed and analysed with the focus on making recommendations for the enhancement and improvement thereof to enable a focus on preparing the next generation of professional intelligence officers.

    Energy and water generation and delivery systems are inherently interconnected. With worldwide demandfor energy growing, the energy sector is experiencing increasing competition for water. With increasingpopulation and changing environmental, socioeconomic, and demographic scenarios, new technology andinvestment decisions must be made for optimized and sustainable energy-water resource management. These decisions require novel scientific insights into the complex interdependencies of energy-water infrastructures across multiple space and time scales.

    Highlights: • Energy and water limit China’s sustainable development. • Current energy policies fail to address water saving issues. • The energy-water coefficient is estimated for both direct use and indirect use. • Water saving effects associated with energy-saving policies is calculated. • Water-energy nexus should be enhanced in key industrial sectors. - Abstract: Energy and water have become major factors limiting sustainable development in China. Energy efficiency and optimization of water management are critical for the healthy growth of the Chinese economy. Current national energy policies fail to adequately address water use issues. Similarly, current water policies do not consider the impact of energy consumption and greenhouse gas emissions. Consequently, few studies have investigated the relationship between energy consumption and water use. The present study analyzes the energy-water nexus in Chinese industries using input–output tables. Coefficients that characterize the relationship between energy consumption and water are used to describe the supply-consumption relationship between the water supply and primary energy sectors. Next, we calculate the water-saving effects associated with the enforcement of energy-saving policies in selected industrial sectors during the eleventh Five-year Plan, from 2005 to 2010. These calculations address the ferrous metals, non-ferrous metals, petrochemical engineering, building materials, and electricity industries as well as key light industries. Our findings indicate that energy-saving efforts in these industries will result in savings in water consumption. This study suggests that a cooperative relationship between water and energy conservation efforts should be an important factor in creating policies that encourage simultaneous savings of both resources. Additionally, the study indicates that government should promote water- and energy-saving techniques in key industrial sectors to encourage

    2016-12-01

    In the sporting context there is a significant nexus between adult workplace harassment and two other critical, developmentally related areas, that of child and adolescent bullying, and college hazing. These are all addressed, albeit obliquely and perhaps inadvertently, in the Miami Dolphins saga and the subsequent NFL Wells Report of 2013-2014. This is a significant document. It is even a brave, if politically expedient milestone. It evaluates the complex inter-personal and inter- and intra-systemic contributions within a sporting organization. Wells also elucidates a case where there is overlapping damage to individuals and systems as a result of malignant bullying, harassment, and hazing within overlapping systems. Constructive approaches to team building, and other positive alternatives to hazing may be the best place to initiate trust and verify institutional change at all these levels.

    2012-01-06

    If maternal atopy and environmental exposure affect prenatal Th cell development, the maternal and fetal immune systems should display common Th1/Th2 phenotypes. To test this hypothesis, we studied maternal and neonatal blood samples from mothers with total serum IgE ordinate IFN-γ production from paired maternal and fetal mononuclear cells, accompanied by co-ordinate increases in activated CD4+CD69+ cells that display the CCR4+Th2 and CXCR3+ Th1 phenotypes. Maternal and fetal CD4+CXCR3+ T cells were subsequently identified as the major producers of IFN-γ. The data established that a transplacental nexus exists during normal pregnancy and that fetal Th cell responses may be biased by the maternal immune system.

    Full Text Available Budget deficits and the debate on the sources of deficit finance have been on the agenda of public economics ever since the 1980s. However recently in the post-communist countries fiscal imbalances appear to be an important problem due to prolonged periods of growing poverty resulting from the transition process. Poverty alleviation policies considerably affect the revenue and expenditure decisions of governments, which are subject to hard budget constraints in an open transitional economy and do not have room for departing from sound fiscal policies. The public finance literature provides a vast number of studies analyzing the relationship between public revenues and expenditures. These studies are mostly characterized by efforts to reveal the attitude of the fiscal authority towards maintaining the budget balance. In this respect, budgetary dynamics in which past government revenues have predictive power on the current level of government expenditures are accepted as evidence of the so-called tax-and-spend hypothesis. On the other hand, the revenue-expenditure nexus running from expenditures to revenues is known in the literature as the spend-and-tax hypothesis. The objective of this study is to analyze empirically the relationship between government revenues and expenditures in four of the transitional economies, i.e. Belarus, Kazakhstan, the Kyrgyz Republic and the Russian Federation. The empirical findings of this study, which are based on Granger causality tests, indicate evidence supporting the tax-and-spend hypothesis in Belarus and the Russian Federation and fiscal synchronization in Kazakhstan and the Kyrgyz Republic. The empirical support for the tax-and-spend hypothesis in these economies implies that increasing government revenues may not end up with lower budget deficits due to their stimulating effect on the demand for public goods and services.

  18. Internationalisation and Innovation Intensities of Polish Manufacturing Firms: A Close Nexus?

    2017-03-01

    Full Text Available Objective: The paper aims at the empirical identification of the nexus between innovation and internationalisation intensities in a sample of Polish manufacturing companies. Research Design & Methods: Using a unique dataset combining micro-level financial data from InfoCredit and results from an extensive survey we follow the approach of Altomonte, Aquilante, Ottaviano & Bekes (2013. We define innovation and internationalisation intensities and analyse the two dimensions disjointly and then simultaneously use formal econometric tools. Findings: Both dimensions are closely and robustly correlated. There is some evidence for the causality going from innovation to internationalisation. Polish manufacturing companies have in general low innovation and internationalisation intensity. Rising innovation intensity allows companies to become more internationalised and in particular, it raises their probability of exporting. Mean characteristics of firms, such as employment, sales or productivity, change along the two examined dimensions. Implications & Recommendations: Our results firmly support the postulates of the heterogeneous firms’ trade theory. The results strongly support the introduction of a new type of economic policy in which internationalisation promotion and innovation promotion are simultaneously targeted at the level of a firm. Contribution & Value Added: We extensively analyse innovation and internationalisation intensities for manufacturing firms from Poland. Using a logit model we show their impact on the likelihood of exporting. We furthermore apply the classification of exporting firms along temporal and geographical dimensions identifying main features and links to the key dimensions.

  19. Conceptual Analysis: The Charcoal-Agriculture Nexus to Understand the Socio-Ecological Contexts Underlying Varied Sustainability Outcomes in African Landscapes

    Directory of Open Access Journals (Sweden)

    2017-06-01

    Full Text Available The production of charcoal is an important socio-economic activity in sub-Saharan Africa (SSA. Charcoal production is one of the leading drivers of rural land-use changes in SSA, although the intensity of impacts on the multi-functionality of landscapes varies considerably. Within a given landscape, charcoal production is closely interconnected to agriculture production both as major livelihoods, while both critically depend on the same ecosystem services. The interactions between charcoal and agricultural production systems can lead to positive synergies of impacts, but will more often result in trade-offs and even vicious cycles. Such sustainability outcomes vary from one site to another due to the heterogeneity of contexts, including agricultural production systems that affect the adoption of technologies and practices. Trade-offs or cases of vicious cycles occur when one-off resource exploitation of natural trees for charcoal production for short-term economic gains permanently impairs ecosystem functions. Given the fact that charcoal, as an important energy source for the growing urban populations and an essential livelihood for the rural populations, cannot be readily substituted in SSA, there must be policies to support charcoal production. Policies should encourage sustainable technologies and practices, either by establishing plantations or by encouraging regeneration, whichever is more suitable for the local environment. To guide context-specific interventions, this paper presents a new perspective—the charcoal-agriculture nexus—aimed at facilitating the understanding of the socio-economic and ecological interactions of charcoal and agricultural production. The nexus especially highlights two dimensions of the socio-ecological contexts: charcoal value chains and tenure systems. Combinations of the two are assumed to underlie varied socio-economic and ecological sustainability outcomes by conditioning incentive mechanisms to affect

    Communicating scientific results to non-technical practitioners is challenging due to their differing interests, concerns and agendas. It is further complicated by the growing number of relevant factors that need to be considered, such as climate change and demographic dynamic. Visualization is an effective method for the scientific community to disseminate results, and it represents an opportunity for the future of water resources systems analysis (WRSA). This study demonstrates an intuitive way to communicate WRSA results to practitioners using interactive web-based visualization tools developed by the JavaScript library: Data-Driven Documents (D3) with a case study in Great Ruaha River of Tanzania. The decreasing trend of streamflow during the last decades in the region highlights the need of assessing the water usage competition between agricultural production, energy generation, and ecosystem service. Our team conduct the advance water resources systems analysis to inform policy that will affect the water-energy-food nexus. Modeling results are presented in the web-based visualization tools and allow non-technical practitioners to brush the graph directly (e. g. Figure 1). The WRSA suggests that no single measure can completely resolve the water competition. A combination of measures, each of which is acceptable from a social and economic perspective, and accepting that zero flows cannot be totally eliminated during dry years in the wetland, are likely to be the best way forward.

  1. From Theory to Practice: Exploring the Organised Crime-Terror Nexus in Sub-Saharan Africa

    2011-09-01

    Full Text Available  A growing body of scholarly literature suggests confluence or even convergence of organized crime and terrorism in various parts of the world. However, links remain somewhat nebulous at this stage and vary considerably, based on region and context. Africa has come under the spotlight due to perceived weaknesses in the criminal justice sector, limited law enforcement capacity, political and systemic corruption, poor border patrol and weak anti-terror and organized crime laws which are believed to provide an ideal environment for the terror-crime nexus to flourish. This article provides an African perspective on the links between organized crime and terror networks in Sub-Saharan Africa, with a particular focus on Southern Africa. The discussion begins with an overview of the theoretical discourse on the subject – relying on African definitions of the contested concepts of ‘terrorism’ and ‘organized crime’ – and will then narrow the analysis on the sub-Saharan case. It relies on an extensive literature review and concludes with empirical findings of a research project on organized crime in Southern Africa, which found no strong empirical links between criminal and terrorist organizations.

    Poverty and land degradation are major problems in majority of world dry lands, where meagre vegetative coverage (of forests and trees) contribute significantly to rural livelihoods. In order to eradicate poverty in the dry lands, it is important to protect the land from deforestation, fragmentation, degradation, drought and sometimes flash floods. Satellite remote sensing is a critical need for India - for spatial and temporal inter-linking of poverty and land degradation nexus and its prioritization. Remote sensing and geographical information system (GIS) is often used to generate and apply knowledge in the complex local context. Connecting natural resources and ecosystem services with attributes of poverty is amenable through Remote Sensing and GIS. Such linkages in a typical local context are important to recognize while building rural assets and natural resources conservation leading to poverty alleviation. A large proportion of the poor in the Rajasthan state live in resource poor western region who lack productive assets (especially land) and also lack adequate livelihoods skills or capacities due to illiteracy. People are inadequately organized to assert their rights and utilize available resources and services. The state also continues to be plagued by high levels of gender and caste discrimination (World Bank, 2007). Incidence of Poverty: The number of population below poverty line in Rajasthan in 2004-05 were 22.1 percent. The corresponding figures for rural areas are 18.7 percent. In urban areas, the number of poor people are 32.9 percent. Rural poverty situation is significantly better than urban poverty. (HDR, 2008) Despite the fact that poverty rates in Rajasthan are lower than the national average, the incidence of poverty in Western Rajasthan is nevertheless high. The incidence of poverty varies between 11.2% in Jodhpur to as much as 35.2% in Jalore. The poor households suffer from both lack of resources and the means to access them, which

    Highlights: • A multi region input–output sustainability assessment model is developed. • Energy-climate-manufacturing nexus within the context of global supply chains is investigated. • Electricity, Gas, and Water Supply sector is the main contributor to energy and carbon impacts. • Turkish regional manufacturing accounts for approximately 40–60% of total carbon emissions. • China, USA, and Rest-of-the World have the largest shares in the Turkish global energy footprint. - Abstract: The main objectives of this research are to improve our understanding of energy-climate-manufacturing nexus within the context of regional and global manufacturing supply chains as well as show the significance of full coverage of entire supply chain tiers in order to prevent significant underestimations, which might lead to invalid policy conclusions. With this motivation, a multi region input–output (MRIO) sustainability assessment model is developed by using the World Input–Output Database, which is a dynamic MRIO framework on the world’s 40 largest economies covering 1440 economic sectors. The method presented in this study is the first environmentally-extended MRIO model that harmonizes energy and carbon footprint accounts for Turkish manufacturing sectors and a global trade-linked carbon and energy footprint analysis of Turkish manufacturing sectors is performed as a case study. The results are presented by distinguishing the contributions of five common supply chain phases such as upstream suppliers, onsite manufacturing, transportation, wholesale, and retail trade. The findings showed that onsite and upstream supply chains are found to have over 90% of total energy use and carbon footprint for all industrial sectors. Electricity, Gas and Water Supply sector is usually found to be as the main contributor to global climate change, and Coke, Refined Petroleum, and Nuclear Fuel sector is the main driver of energy use in upstream supply chains. Overall, the

    Full Text Available This paper reflects a study in how the Slovenian art collective the NSK (Neue Slowenische Kunst, and more specifically its sub-group Laibach, interrogate the representation of Central and Eastern European cultural memory in the context of post-Socialism, and operate as a nexus between Eastern Europe and the West. Emerging in the wake of Tito's death and shaped by the break-up of Yugoslavia, the NSK were founded in 1984, in Ljubljana (northern Slovenia.  The NSK is a multi-disciplinary collective primarily comprised of three groups: IRWIN (visual arts, Noordung (theatre, and its most influential delivery system, Laibach (music.  Brought to academic scrutiny in the West by Slavoj Žižek for their subversive strategy of over-identification with the totalitarian spectacle, Laibach are Slovenia’s most famous cultural export, with a global following, and an international and domestic history of controversy. With the strategy of Retrogardism, Laibach and the NSK re-mythologise totalitarian iconography associated with Nazi Kunst and Socialist Realism.  Through this process of re-mythologisation Laibach explore the unfinished narrative of Communism and the legacy of the European traumatic historical in the context of a ‘post-ideological’ age.

    The study is a qualitative approach and looks into new ways for the effective energy management of a wind farm (WF) operation in a suburban or near-urban environment in order the generated electricity to be utilised for hydroponic farming purposes as well. Since soilless hydroponic indoor systems gain more and more attention one basic goal, among others, is to take advantage of this not typical electricity demand and by managing it, offering to the grid a less fluctuating electricity generation signal. In this paper, a hybrid business model is presented where the Distributed Energy Resources (DER) producer is participating in the electricity markets under competitive processes (spot market, real-time markets etc.) and at the same time acts as a retailer offering - based on the demand - to the hydroponic units for their mass deployment in an area, putting forward an integrated energy-food nexus approach.

    2017-03-01

    This article attempts to explore the nexus between oil consumption, economic growth and carbon dioxide (CO 2 ) emissions in three East Asian oil importing countries (i.e. China, South Korea and Japan) over the period 1980-2013, by using the Granger causality, Johansen cointegration test, Generalised Impulse Response functions (GIRF) and variance decompositions. The empirical findings provide evidence for the existence of a long-run relationship between oil consumption and economic growth in China and Japan. The results also point to a uni-directional causality from running from oil consumption to economic growth in China and Japan, and from oil consumption to CO 2 emissions in South Korea. The overall results of GIRF reveal that while economic growth in China and South Korea shows a positive response to oil consumption, this variable responses negatively to the same shock in Japan. In addition, oil consumption spikes cause a negative response of CO 2 emissions in Japan and China, as well as a U-shape response in South Korea.

  8. Should she be granted asylum? Examining the justifiability of the persecution criterion and nexus clause in asylum law

    Directory of Open Access Journals (Sweden)

    Noa Wirth Nogradi

    2016-10-01

    Full Text Available The current international asylum regime recognizes only persecuted persons as rightful asylum applicants. The Geneva Convention and Protocol enumerate specific grounds upon which persecution is recognized. Claimants who cannot demonstrate a real risk of persecution based on one of the recognized grounds are unlikely to be granted asylum. This paper aims to relate real-world practices to normative theories, asking whether the Convention’s restricted preference towards persecuted persons is normatively justified. I intend to show that the justifications of the persecution criterion also apply to grounds currently lacking recognition. My main concern will be persecution on the grounds of gender.The first section introduces the dominant standpoints in theories of asylum, which give different answers to the question of who should be granted asylum, based on different normative considerations. Humanitarian theories base their claims on the factual neediness of asylum-seekers, holding that whoever is in grave danger of harm or deprivation should be granted asylum. Political theories base their justifications on conceptions of legitimacy and membership, holding that whoever has been denied membership in their original state should be granted asylum. Under political theories, Matthew Price’s theory will be discussed, which provides a normative justification of the currently recognized persecution criterion. The second section provides a descriptive definition of persecution based on Kuosmanen (2014, and evaluates the normative relevance of the different elements of this definition based on the theories presented previously. The third section is devoted to the examination of the normative justifiability of the nexus clause’s exclusive list of the bases (grounds upon which persons might be persecuted. The section argues that while the clause does not recognize that persecution might be based on gender, in fact many women experience harms based on

Approximately 1,000 participants attended the event from the fields of science, engineering, federal and local government, business, and civil society. The conference developed and advanced partnerships focusing on strategies and initiatives to address the world’s interconnected food, water and energy systems, specifically how to provide these resources to a population of 9 billion people by midcentury without overwhelming the environment. The conference emphasized actionable outcomes—moving forward on policy and practice with a focus on “opportunities for impact” on the most critical issues in the relatively near term.

  11. The water energy nexus, an ISO50001 water case study and the need for a water value system

    2015-06-01

    Full Text Available The world’s current utilisation of water, allied to the forecasted increase in our dependence on it, has led to the realisation that water as a resource needs to be managed. The scarcity and cost of water worldwide, along with water management practices within Europe, are highlighted in this paper. The heavy dependence of energy generation on water and the similar dependence of water treatment and distribution on energy, collectively termed the water–energy nexus, is detailed. A summary of the recently launched ISO14046 Water Footprint Standard along with other benchmarking measures is outlined and a case history of managing water using the Energy Management Standard ISO50001 is discussed in detail. From this, the requirement for a methodology for improvement of water management has been identified, involving a value system for water streams, which, once optimised will improve water management including efficiency and total utilisation.

    Marine mammals are both icons of Arctic marine ecosystems and fundamental to Native subsistence nutrition and culture. Eight species are endemic to the Pacific Arctic, including the polar bear, walrus, ice seals (4 species), beluga and bowhead whales. Studies of walrus and bowheads have been conducted over the past 30 years, to estimate population size and elucidate patterns of movement and abundance. With regard to the three pillars of the SEARCH program, these long-term OBSERVATIONS provide a foundation for research seeking to UNDERSTAND and RESPOND to the effects of rapid climate change on the marine ecosystem. Specifically, research on the coastal ecosystem near Barrow, Alaska focuses on late-summer feeding habitat for bowheads in an area where whales are hunted in autumn. This work is a partnership among agency, academic and local scientists and the residents of Barrow, all of whom seek to better UNDERSTAND how recent dramatic changes in sea ice, winds and offshore industrial activities influence whale movements and behavior. In regard to RESPONDING to climate change, the nascent Sea Ice for Walrus Outlook (SIWO) is a science partnership that projects sea ice and wind conditions for five villages in the Bering Strait region. The objective of the SIWO is to provide information on physical conditions in the marine environment at spatial and temporal scales relevant to walrus hunters. Marine mammals are a strong and dynamic nexus for partnerships among scientists, Arctic residents, resource managers and the general public - as such, they are essential elements to any science plan for a sustainable Arctic.

  15. The energy-water nexus: are there tradeoffs between residential energy and water consumption in arid cities?

    2014-09-01

    Water scarcity, energy consumption, and air temperature regulation are three critical resource and environmental challenges linked to urban population growth. While appliance efficiency continues to increase, today's homes are larger and residents are using more energy-consuming devices. Recent research has often described the energy-water nexus as a "tradeoff" between energy and water due to reduced temperatures resulting from irrigated vegetation. Accordingly, some arid cities have implemented landscape-conversion programs that encourage homeowners to convert their yards from grass (mesic) to drought-tolerant (xeric) landscapes to help conserve water resources. We investigated these relationships in Phoenix, Arizona by examining energy and water data for the summer months of June-September 2005 while temperature variability was analyzed from a local heat wave. Results show parallel consumption patterns with energy and water use strongly correlated and newer homes using more of both. The counterintuitive findings show that "drought-resistant" models may not be beneficial for community health, environment, or economics and that this issue is further complicated by socio-economic variables.

    Gravel-bed river floodplains in mountain landscapes disproportionately concentrate diverse habitats, nutrient cycling, productivity of biota, and species interactions. Although stream ecologists know that river channel and floodplain habitats used by aquatic organisms are maintained by hydrologic regimes that mobilize gravel-bed sediments, terrestrial ecologists have largely been unaware of the importance of floodplain structures and processes to the life requirements of a wide variety of species. We provide insight into gravel-bed rivers as the ecological nexus of glaciated mountain landscapes. We show why gravel-bed river floodplains are the primary arena where interactions take place among aquatic, avian, and terrestrial species from microbes to grizzly bears and provide essential connectivity as corridors for movement for both aquatic and terrestrial species. Paradoxically, gravel-bed river floodplains are also disproportionately unprotected where human developments are concentrated. Structural modifications to floodplains such as roads, railways, and housing and hydrologicaltering hydroelectric or water storage dams have severe impacts to floodplain habitat diversity and productivity, restrict local and regional connectivity, and reduce the resilience of both aquatic and terrestrial species, including adaptation to climate change. To be effective, conservation efforts in glaciated mountain landscapes intended to benefit the widest variety of organisms need a paradigm shift that has gravel-bed rivers and their floodplains as the central focus and that prioritizes the maintenance or restoration of the intact structure and processes of these critically important systems throughout their length and breadth.

  19. Sylvia Docker lecture: the practice, research, policy nexus in contemporary occupational therapy.

    2014-04-01

    In this era of evidence-based practice, Australian occupational therapists largely accept scientific perspectives of the quality of evidence and 'what makes a strong study'. Yet unequal power relationships are usual between funders who set the research agenda, researchers and people who are the subjects of research. Emerging policy now mandates partnerships with consumers in any health and research projects about them. Are we person-centred in our research practices? What difference would increased consumer direction make to our research methods, scope and outcomes? This lecture describes some of the benefits and challenges of collaborative or inclusive research partnerships with consumers and outlines where this may take occupational therapy in future. The disability community's calls for inclusive research will be contrasted with mainstream research approaches and with occupational therapy's commitment to person-centredness. An example of inclusive research undertaken by the author and colleagues with disabilities which posed the question: 'What difference does assistive technology make to life for people living with impairment?' will be presented. Collaborative research is best conceptualised as a mutually productive journey, with many factors influencing how fully inclusive research principles can be realised. The possibilities and complexities of conducting research which has inclusive credentials are outlined. Inclusive research principles provide a means to enact person-centredness in research as well as practice. Following these principles challenges occupational therapy practitioners and researchers to address nexus issues: that is, intersections between and beyond research, policy and practice. © 2014 Occupational Therapy Australia.

    2018-02-01

    Full Text Available Many countries, like South Africa, Australia, India, China and the United States, are highly dependent on coal fired power stations for energy generation. These power stations require significant amounts of water, particularly when fitted with technology to reduce pollution and climate change impacts. As water resources come under stress it is important that spatial variability in water availability is taken into consideration for future energy planning particularly with regards to motivating for a switch from coal fired power stations to renewable technologies. This is particularly true in developing countries where there is a need for increased power production and associated increasing water demands for energy. Typically future energy supply options are modelled using a least cost optimization model such as TIMES that considers water supply as an input cost, but is generally constant for all technologies. Different energy technologies are located in different regions of the country with different levels of water availability and associated infrastructure development and supply costs. In this study we develop marginal cost curves for future water supply options in different regions of a country where different energy technologies are planned for development. These water supply cost curves are then used in an expanded version of the South Africa TIMES model called SATIM-W that explicitly models the water-energy nexus by taking into account the regional nature of water supply availability associated with different energy supply technologies. The results show a significant difference in the optimal future energy mix and in particular an increase in renewables and a demand for dry-cooling technologies that would not have been the case if the regional variability of water availability had not been taken into account.

    Increasing pressure affects water resources, especially in the agricultural sector, with cascading impacts on energy consumption. This is particularly relevant in the Mediterranean area, showing significant water scarcity problems, further exacerbated by the crucial economic role of agricultural production. Assessing the sustainability of water resource use is thus essential to preserving ecosystems and maintaining high levels of agricultural productivity. This paper proposes an integrated methodology based on the Water-Energy-Food Nexus to evaluate the multi-dimensional implications of irrigation practices. Three different indices are introduced, based on an analysis of the most influential factors. The methodology is then implemented in a catchment located in Puglia (Italy) and a comparative analysis of the three indices is presented. The results mainly highlight that economic land productivity is a key driver of irrigated agriculture, and that groundwater is highly affordable compared to surface water, thus being often dangerously perceived as freely available.

  3. Soils and public health: the vital nexus

    Pachepsky, Yakov

    2015-04-01

    Soils sustain life. They affect human health via quantity, quality, and safety of available food and water, and via direct exposure of individuals to soils. Throughout the history of civilization, soil-health relationships have inspired spiritual movements, philosophical systems, cultural exchanges, and interdisciplinary interactions, and provided medicinal substances of paramount impact. Given the climate, resource, and population pressures, understanding and managing the soil-health interactions becomes a modern imperative. We are witnessing a paradigm shift from recognizing and yet disregarding the 'soil-health' nexus complexity to parameterizing this complexity and identifying reliable controls. This becomes possible with the advent of modern research tools as a source of 'big data' on multivariate nonlinear soil systems and the multiplicity of health metrics. The phenomenon of suppression of human pathogens in soils and plants presents a recent example of these developments. Evidence is growing about the dependence of pathogen suppression on the soil microbial community structure which, in turn, is affected by the soil-plant system management. Soil eutrophication appears to create favorable conditions for pathogen survival. Another example of promising information-rich research considers links and feedbacks between the soil microbial community structure and structure of soil physical pore space. The two structures are intertwined and involved in the intricate self-organization that controls soil services to public health. This, in particular, affects functioning of soils as a powerful water filter and the capacity of this filter with respect to emerging contaminants in both 'green' and 'blue' waters. To evaluate effects of soil services to public health, upscaling procedures are needed for relating the fine-scale mechanistic knowledge to available coarse-scale information on soil properties and management. More needs to be learned about health effects of soils

    HIV prevalence remains high among men who have sex with men (MSM) in the United States, yet the majority of research has focused on MSM as individuals, not as dyads, and has discussed HIV risks primarily in the context of casual sex. Nexus is an online prevention program that combines home-based HIV testing and couples HIV testing and counseling (CHTC). It allows partners in dyadic MSM relationships to receive HIV testing and care in the comfort of their designated residence, via video-based chat. By using video-based technologies (eg, VSee video chat), male couples receive counseling and support from a remote online counselor, while testing for HIV at home. This randomized control trial (RCT) aims to examine the effects of video-based counseling combined with home-based HIV testing on couples' management of HIV risk, formation and adherence to explicit sexual agreements, and sexual risk-taking. The research implements a prospective RCT of 400 online-recruited male couples: 200 self-reported concordant-negative couples and 200 self-reported discordant couples. Couples in the control arm will receive one or two home-based HIV self-testing kits and will be asked to report their results via the study's website. Couples in the experimental arm will receive one or two home-based HIV self-testing kits and will conduct these tests together under the facilitation of a remotely located counselor during a prescheduled VSee-based video CHTC session. Study assessments are taken at baseline, as well as at 3- and 6-month follow-up sessions. Project Nexus was launched in April 2016 and is ongoing. To date, 219 eligible couples have been enrolled and randomized. Combining home-based HIV testing with video-based counseling creates an opportunity to expand CHTC to male couples who (1) live outside metro areas, (2) live in rural areas without access to testing services or LGBTQ resources, or (3) feel that current clinic-based testing is not for them (eg, due to fears of

    The launch of China's new national urbanization plan, coupled with increasing concerns about air pollution, calls for better understandings of the nexus between urbanization and the air pollution-related health. Based on refined estimates of PM 2.5 related mortality in China, we developed an Urbanization-Excess Deaths Elasticity (U-EDE) indicator to measure the marginal PM 2.5 related mortality caused by urbanization. We then applied statistical models to estimate U-EDE and examined the modification effects of income on U-EDE. Urbanization in China between 2004 and 2012 led to increased PM 2.5 related mortality. A 1% increase in urbanization was associated with a 0.32%, 0.14%, and 0.50% increase in PM 2.5 related mortality of lung cancer, stroke, and ischemic heart disease. U-EDEs were modified by income with an inverted U curve, i.e., lower marginal impacts at the lowest and highest income levels. In addition, we projected the future U-EDE trend of China as a whole and found that China had experienced the peak of U-EDE and entered the second half of the inverted U-shaped curve. In the near future, national average U-EDE in China will decline along with the improvement of income level if no dramatic changes happen. However, the decreased U-EDE only implies that marginal PM 2.5 -related mortality brought by urbanization would decrease in China. Total health damage of urbanization will keep going up in the predictable future because the U-EDE is always positive. Copyright © 2017 Elsevier Ltd. All rights reserved.

  8. Meeting Disorders.

    2017-12-01

    Although meetings are central to organizational work, considerable time devoted to meetings in Academic Health Centers appears to be unproductively spent. The primary purposes of this article are to delineate and describe Meeting Disorders, pathological processes resulting in these inefficient and ineffective scenarios, and Meeting Fatigue Disorder (MFD), a clinical syndrome. The paper also offers preliminary approaches to remedies. The authors integrate observations made during tens of thousands of hours in administrative meetings in academic medical settings with information in the literature regarding the nature, causes and potential interventions for dysfunctional groups and meetings. Meeting Disorders, resulting from distinct pathologies of leadership and organization, constitute prevalent subgroups of the bureaucrapathologies, pathological conditions caused by dysfunctional bureaucratic processes that generate excesses of wasted time, effort, and other resources. These disorders also generate frustration and demoralization among participants, contributing to professional burnout. Meeting Fatigue Disorder (MFD) is a subjective condition that develops in individuals who overdose on these experiences and may reflect one manifestation of burnout. Meeting disorders and Meeting Fatigue Disorder occur commonly in bureaucratic life. Resources and potential remedies are available to help ameliorate their more deleterious effects.

    2017-04-04

    The University of Texas at Austin and The Technical University of Munich 2015 Solar Decathlon house is called Nexushaus because it combines UT Austin and TUM students in an affordable modular residential green building in the context of Austin, Texas, based on shape forming principles found in nature that demonstrates transformative technologies in Zero Net Energy, Zero Net Water and Carbon Neutrality. To meet the needs of the competition, a portable modular design has been developed with an assembly that enables ease of installation and both quantitative and qualitative performance in the design. The prefabricated house sits lightly on the land and forms the superstructure for photovoltaic technologies, rainwater collection, aquaculture and permaculture gardening and indoor/outdoor living. The ultimate goal of Nexushaus is to serve as a potential prototype for a next-generation modular home that could be reproduced in mass in an assembly plant in Austin.

    2015-12-01

    This study investigates the relationship between energy consumption and carbon dioxide emission in the causal framework, as the direction of causality remains has a significant policy implication for developed and developing countries. The study employed maximum entropy bootstrap (Meboot) approach to examine the causal nexus between energy consumption and carbon dioxide emission using bivariate as well as multivariate framework for Malaysia, over a period of 1975-2013. This is a unified approach without requiring the use of conventional techniques based on asymptotical theory such as testing for possible unit root and cointegration. In addition, it can be applied in the presence of non-stationary of any type including structural breaks without any type of data transformation to achieve stationary. Thus, it provides more reliable and robust inferences which are insensitive to time span as well as lag length used. The empirical results show that there is a unidirectional causality running from energy consumption to carbon emission both in the bivariate model and multivariate framework, while controlling for broad money supply and population density. The results indicate that Malaysia is an energy-dependent country and hence energy is stimulus to carbon emissions.

  13. Targeting the eIF4F translation initiation complex: a critical nexus for cancer development.

    Science.gov (United States)

    Pelletier, Jerry; Graff, Jeremy; Ruggero, Davide; Sonenberg, Nahum

    2015-01-15

    Elevated protein synthesis is an important feature of many cancer cells and often arises as a consequence of increased signaling flux channeled to eukaryotic initiation factor 4F (eIF4F), the key regulator of the mRNA-ribosome recruitment phase of translation initiation. In many cellular and preclinical models of cancer, eIF4F deregulation results in changes in translational efficiency of specific mRNA classes. Importantly, many of these mRNAs code for proteins that potently regulate critical cellular processes, such as cell growth and proliferation, enhanced cell survival and cell migration that ultimately impinge on several hallmarks of cancer, including increased angiogenesis, deregulated growth control, enhanced cellular survival, epithelial-to-mesenchymal transition, invasion, and metastasis. By being positioned as the molecular nexus downstream of key oncogenic signaling pathways (e.g., Ras, PI3K/AKT/TOR, and MYC), eIF4F serves as a direct link between important steps in cancer development and translation initiation. Identification of mRNAs particularly responsive to elevated eIF4F activity that typifies tumorigenesis underscores the critical role of eIF4F in cancer and raises the exciting possibility of developing new-in-class small molecules targeting translation initiation as antineoplastic agents. ©2014 American Association for Cancer Research.

  14. The charcoal-degradation nexus: contested 'fuelscapes' in the sub-Saharan drylands of northern Kenya

    2017-04-01

    Charcoal ranks amongst the most commercialized but least regulated commodities in sub-Saharan Africa. Despite its prevalence as an energy source for cooking and heating, localized environmental and livelihood impacts of charcoal production are poorly understood so far. The identified research deficit is amplified by widespread negative views of this activity as a poverty-driven cause of deforestation and land degradation. However, the charcoal-degradation nexus is apparently more complicated, not least because the extraction of biomass from already degraded woodlands can also be interpreted as an appropriate option under given management regimes. In order to better calibrate existing research agendas to site-specific geographies of charcoal production, we propose a re-conceptualization of such energy landscapes as 'fuelscapes' with complex material and social dimensions. The concept is tested with reference to a case study in Central Pokot, northern Kenya, where charcoal production only began in the early 1990's. Based on the assumption that the fine line between sustainable land management and degradation in dryland energy landscapes is not only highly variable but also increasingly contested, our study combines the knowledge input of different stakeholders with longitudinal time series of remote sensing data. Based on the results of our interdisciplinary analyses, we outline an integrated tool for the co-operative monitoring and management of prevailing degradation processes against the background of diversified livelihood activities in sub-Saharan drylands.

  15. Assessment of food-water nexus by water footprint: a case study in Saskatchewan, Canada

    Zhao, Y.; Si, B.

    2016-12-01

    It is important but challengeable to understand the water-food nexus complexity. The water footprint (WF), a relatively new index, is a comprehensive indicator that can be used to evaluate crop water production. This paper aims to 1) determine how water footprint changes at different crop rotational types; 2) investigate what is difference if WF is calculated by yield-based or protein-based; and 3) explore how virtual water flows are responding to regional meteorological, agricultural, and socio-economic factors. The result provided the water footprint and virtual water flow exemplified for Saskatchewan agri-food production industries. By using the water footprint, we determined the best rotation for pulse crops in terms of efficiency of water productivity and water-saving opportunity. While yield is a comprehensive index to assess the productivity (yield-based WF), it underestimated the contribution of some crops, such as pulse crops with relatively low yield but high protein contents (protein-based WF). Consequently, we concluded that water-saving benefits can be achieved by the development and adoption of water efficient technology and better virtual water flows may be achieved by increased area of low water footprint in Saskatchewan. Our finding improves the current concepts of water and food security, informs production and trade decisions, and thus suggests optimal strategies by reduced water footprints in terms of agricultural management.

  17. Foucault, fields of governability, and the population–family–economy nexus in China.

    Science.gov (United States)

    Thompson, Malcolm

    2012-01-01

    It was only in the early twentieth century that China discovered that it had a population, at least if a population is understood not as a simple number of people but instead in terms of such features as variable levels of health, birth and death rates, age, sex, dependency ratios, and so on—as an object with a distinct rationality and intrinsic dynamics that can be made the target of a specific kind of direct intervention. In 1900, such a developmentalist conception of the population simply did not exist in China; by the 1930s, it pervaded the entire social and political field from top to bottom. Through a reading of a series of foundational texts in population and family reformism in China, this paper argues that this birth of the Chinese population occurred as a result of a general transformation of practices of governing, one that necessarily also involved a reconceptualization of the family and a new logic of overall social rationalization; in short, the isolation of a population–family–economy nexus as a central field of modern governing. This process is captured by elaborating and extending Foucault's studies of the historical emergence of apparatuses (dispositifs) into a notion of fields of governability. Finally, this paper argues that the one-child policy, launched in the late 1970s, should be understood not in isolation from the imposition of the “family-responsibility system” in agriculture and market reforms in exactly that period, but as part—mutatis mutandis—of a return to a form of governing that was developed in the first half of the twentieth century.

    This study presents the nexus of food, energy and water framework in the context of small scale irrigation for vegetable production during the dry season in an irrigated agriculture system in Ethiopia. The study is based on detailed data collected in three sites of the Innovation Lab for Small Scale Irrigation (ILSSI) project in Ethiopia. The sites were Robit, Dangishta and Lemo and detailed field data was collected in 18 households in each site. The field data collected includes crop management (such as irrigation amount and dates, fertilizer rates, tillage practices, irrigation technologies, etc.) and agricultural production (crop yield, biomass, etc.) on tomato, onion and cabbage during the dry season. Four different water lifting technologies - namely rope with pulley and bucket, rope and washer pump, solar pump and motor pump - were used for water withdrawal from shallow groundwater wells. The Soil and Water Assessment Tool (SWAT) and Agricultural Policy Environmental eXtender (APEX) models were used in an integrated manner to assess water resource potential and develop water use efficiency of vegetables, which is a relationship between amount of water applied and vegetable yield. The water use efficiency for each vegetable crops were translated into energy requirement as pumping hours and potential irrigable areas for the water lifting technologies. This integrated approach was found useful to optimize water and energy use for sustainable food production using small scale irrigation. The holistic approach will not only provide a significant contribution to achieving food self-sufficiency, but will also be effective for optimizing agricultural input.

    The sustainable use of common pool resources has become a significant global challenge. It is now widely accepted that specific mechanisms such as community-based management strategies, institutional responses such as resource privatization, information availability and emergent social norms can be used to constrain individual 'harvesting' to socially optimal levels. However, there is a paucity of research focused specifically on aligning profitability and sustainability goals. In this paper, an integrated mathematical model of a common pool resource game is developed to explore the nexus between the underlying costs and benefits of harvesting decisions and the sustainable level of a shared, dynamic resource. We derive optimal harvesting efforts analytically and then use numerical simulations to show that individuals in a group can learn to make harvesting decisions that lead to the globally optimal levels. Individual agents make their decision based on signals received and a trade-off between economic and ecological sustainability. When the balance is weighted towards profitability, acceptable economic and social outcomes emerge. However, if individual agents are solely driven by profit, the shared resource is depleted in the long run - sustainability is possible despite some greed, but too much will lead to over-exploitation.

    A frustration often expressed by researchers and policy-makers in public health is an apparent mismatch between respective priorities and expectations for research. Academics bemoan an oversimplification of their work, a reticence for independent critique and the constant pressure to pursue evaluation funding. Meanwhile, policy-makers look for research reports written in plain language with clear application, which are attuned to current policy settings and produced quickly. In a context where there are calls in western nations for evidence based policy with stronger links to academic research, such a mismatch can present significant challenges to policy program evaluation. The purpose of this paper is to present one attempt to overcome these challenges. Specifically, the paper describes the development of a conceptual framework for a large-scale, multifaceted evaluation of an Australian Government health initiative to expand Nurse Practitioner models of practice in aged care service delivery. In doing so, the paper provides a brief review of key points for the facilitation of a strong research-policy nexus in public health evaluations, as well as describes how this particular evaluation embodies these key points. As such, the paper presents an evaluation approach which may be adopted and adapted by others undertaking public health policy program evaluations. Copyright © 2013 Elsevier Ltd.

    The Phoenix Active Management Area (AMA) is an administrative region of 14,500 km2 identified by the Arizona Department of Water Resources with the aim of reaching and maintaining the safe yield (i.e. balance between annual amount of groundwater withdrawn and recharged) by 2025. The AMA includes the Phoenix metropolitan area, which has experienced a dramatic population growth over the last decades with a progressive conversion of agricultural land into residential land. As a result of these changes, the water and energy demand as well as the food production in the region have significantly evolved over the last 30 years. Given the arid climate, a crucial role to support this growth has been the creation of a complex water supply system based on renewable and non-renewable resources, including the energy-intensive Central Arizona Project. In this talk, we present a preliminary characterization of the evolution in time of the feedbacks between food, water, and energy in the Phoenix AMA by analyzing secondary data (available from water and energy providers, irrigation districts, and municipalities), as well as satellite imagery and primary data collected by the authors. A preliminary visual analytics framework is also discussed describing current design practices and ideas for exploring networked components and cascading impacts within the FEW Nexus. This analysis and framework represent the first steps towards the development of an integrated modeling, visualization, and decision support infrastructure for comprehensive FEW systems decision making at decision-relevant temporal and spatial scales.

    Full Text Available This paper attempts to contribute to ways by which confluence, referring to a meeting point for the different agents to cooperate and communicate on education policy processes, can be understood. Pertinent national education policies in countries receiving aid, in particular, are formed and implemented in a complex nexus. Cultural and context sensitivity can be stimulated through a thorough understanding of this confluence, which subsequently can enable the different policy agents, which function at this meeting point, collaborate to alleviate some of the educational challenges. Comparative and international education, in this respect, has a significant role to play.

  5. Leveraging the water-energy-food nexus for a sustainability transition: Institutional and policy design choices in a fragmented world (Invited)

    2013-12-01

    Given the critical - but often subtle - feedbacks between water, energy, and food security, a nexus approach that integrates management and governance across sectors and scales is increasingly being advocated in research and policy circles. As a first step, such an approach calls for an integrated multi-disciplinary assessment of the externalities across sectors and tradeoffs involved in enhancing security in one sector on the other sectors. Recent research efforts have focused on understanding these tradeoffs, say, through estimating the energy costs of expanding irrigation for greater food security; or estimating the embodied land and water costs in increased energy production. While such efforts have increased awareness about the inter-connectedness of such issues, the fundamental question of how such an understanding influences decision-making and how it can lead to coordinated action towards a transition to more sustainable pathways still remains largely unanswered. The long legacy of sectoral organization of political and bureaucratic structures has led to a fragmentary policy and institutional landscape, on which cross-sectoral public action and coordination poses several challenges. Moreover, poorly defined property rights, imperfect or absent markets, and uncertainty about resource dynamics imply that economic signals about relative scarcity in one sector are not necessarily clear to decision makers in the other sectors. In this study, we examine these issues related to water-energy food nexus in the context of semi-arid groundwater irrigated regions of western and southern India. Using a social-ecological systems framework, we begin by characterizing some of the key inter-dependencies among food, water, and energy at the farm household, village and state level. We then examine the factors that influence decision-making at these levels, and the extent to which these decisions internalize the externalities. Specifically, we examine the role of energy

    The water-energy-food (WEF) nexus has been promoted in recent years as an intersectional concept designed to improve planning and regulatory decision-making across the three sectors. The production and consumption of water, energy and food resources are inextricably linked across multiple spatial scales (from the global to the local), but a common feature is competition for land which through different land management practices mediates provisioning ecosystem services. The nexus perspective seeks to understand the interlinkages and use systems-based thinking to frame management options for the present and the future. It aims to highlight advantage and minimise damaging and unsustainable outcomes through informed decisions regarding trade-offs inclusive of economic, ecological and equity considerations. Operationalizing the WEF approach is difficult because of the lack of complete data, knowledge and observability - and the nature of the challenge also depends on the scale of the investigation. Transboundary river basins are particularly challenging because whilst the basin unit defines the hydrological system this is not necessarily coincident with flows of food and energy. There are multiple national jurisdictions and geopolitical relations to consider. Land use changes have a profound influence on hydrological, agricultural, energy provisioning and regulating ecosystem services. Future policy decisions in the water, energy and food sectors could have profound effects, with different demands for land and water resources, intensifying competition for these resources in the future. In this study, we used Google Earth Engine (GEE) to analyse the land cover changes in the Zambezi river basin (1.4 million km2) from 1992 to 2015 using the European Space Agency annual global land cover dataset. Early results indicate transformative processes are underway with significant shifts from tree cover to cropland, with a 4.6 % loss in tree cover and a 16 % gain in cropland

    Immediate action is required in the Mediterranean to address environmental degradation that is mainly driven by consumption patterns. Increasing stress on biological and social systems is put by unsustainable consumption patterns. Food consumption patterns are important drivers of environment degradation. The objective of this review paper is to explore natural resources-food nexus in the Mediterranean region by highlighting the environmental footprints of the current consumption and production patterns. Secondary data from different sources such as FAOSTAT, the World Bank, Water Footprint Network (WFN), and Global Footprint Network were used to analyze the situation in 21 Mediterranean countries. The region faces many environmental challenges, e.g., land degradation, water scarcity, environment pollution, biodiversity loss, and climate change. The current consumption patterns imply high ecological, carbon, and water footprints of consumption and unfavorable national virtual-water balances. Food Balance Sheets data show that the contribution of vegetal and animal-based food product groups to food supply is variable among the Mediterranean countries. This has implications also in terms of the WF of food supply, which was calculated for Bosnia, Egypt, Italy, Morocco, and Turkey. The WF of the current diet resulted lower than that of the proposed Mediterranean one in the case of Italy. There is a strong scientific evidence supporting assumption that it is so also for other Mediterranean countries. The Mediterranean is characterized by a high resource use intensity that is further exacerbated by food losses and waste (FLW). In fact, FLW implies the loss of precious resources (water, land, energy) and inputs (fertilizers). Therefore, it is crucial to increase adherence to the traditional Mediterranean diet and to reduce FLW in order to foster transition to more sustainable food consumption patterns thus reducing pressure on the scarce resources of the Mediterranean

    Sinnathurai Vijayakumar

    2013-06-01

    Full Text Available The paper has scrutinized the nexus among poverty, economic growth, employment and dependency ratio in developing countries. The primary intension behind this study is to find out the association between variables such as poverty, economic growth, agricultural and industrial employment and dependency ratio due to the gap in the existing literature. This study fully relies on cross country data and involves forty one countries which have been selected from Asia,Latin America and Sub-Saharan Africa. For this study, OLS method, correlation and econometric tools have been employed. Two models employed in the analysis are goodness of fit because both p-value and F-statistics in the models are less than 5%. The results bring to light the fact that age dependency ratio has had a tremendous impact on poverty and poverty has had a relatively very high impact on the age dependency ratio. Even though Industrial employment has anegative association with poverty incidence, it does not have a significant impact on poverty. The finding that economic growth, poverty and industrial employment significantly affect the agedependency ratio in model two is practicable and consistent with economic theories. Thus stable economic growth with an increase in labour productivity and labour intensive technology is anactive remedy for solving this problem.

    In recent years, increscent emissions in the city of Beijing due to expanded population, accelerated industrialization and inter-regional pollutant transportation have led to hazardous atmospheric pollution issues. Although a number of anthropogenic control measures have been put into use, frequent/severe haze events have still challenged regional governments. In this study, a hybrid population-production-pollution nexus model (PPP) is proposed for air pollution management and air quality planning (AMP) with the aim to coordinate human activities and environmental protection. A fuzzy-stochastic mixed quadratic programming method (FSQ) is developed and introduced into a PPP for tackling atmospheric pollution issues with uncertainties. Based on the contribution of an index of population-production-pollution, a hybrid PPP-based AMP model that considers employment structure, industrial layout pattern, production mode, pollutant purification efficiency and a pollution mitigation scheme have been applied in Beijing. Results of the adjustment of employment structure, pollution mitigation scheme, and green gross domestic product under various environmental regulation scenarios are obtained and analyzed. This study can facilitate the identification of optimized policies for alleviating population-production-emission conflict in the study region, as well as ameliorating the hazardous air pollution crisis at an urban level.

  19. A fresh recipe for designers: HCI approach to explore the nexus between design techniques and formal methods in software development

    Directory of Open Access Journals (Sweden)

    Julian Galindo Losada

    2016-11-01

    Full Text Available Emerging companies involved in design and implementation of innovative products demand multidisciplinary teams to be competitive in the market. This need mainly exposes designers to extend their knowledge not only in User Interface elements of the design process but also in software methodologies to cover the lack of resources and expertise in start-ups. It raises the question of how designers can line up HCI techniques with best practices in software development while preserving usability and easy-to-use principles. To explore this gap, this paper proposes an approach which combines existing technology and methods by studying the nexus between HCI prototyping and software engineering. The approach is applied into a case study in the design of a virtual shop harmonizing the use of storyboards and the spiral. A comprehensive analysis is performed by using a Technology acceptance model (TAM regarding with two variables: usability and easy-to-use. The present finding underlines the positive integration of HCI techniques and formal methods without compromising user satisfaction with a potential benefit for small companies in a formation stage.

  2. Catchment scale water resource constraints on UK policies for low-carbon energy system transition

    Science.gov (United States)

    Konadu, D. D.; Fenner, R. A.

    2017-12-01

    Long-term low-carbon energy transition policy of the UK presents national scale propositions of different low-carbon energy system options that lead to meeting GHG emissions reduction target of 80% on 1990 levels by 2050. Whilst national-scale assessments suggests that water availability may not be a significant constrain on future thermal power generation systems in this pursuit, these analysis fail to capture the appropriate spatial scale where water resource decisions are made, i.e. at the catchment scale. Water is a local resource, which also has significant spatio-temporal regional and national variability, thus any policy-relevant water-energy nexus analysis must be reflective of these characteristics. This presents a critical challenge for policy relevant water-energy nexus analysis. This study seeks to overcome the above challenge by using a linear spatial-downscaling model to allocate nationally projected water-intensive energy system infrastructure/technologies to the catchment level, and estimating the water requirements for the deployment of these technologies. The model is applied to the UK Committee on Climate Change Carbon Budgets to 2030 as a case study. The paper concludes that whilst national-scale analyses show minimal long-term water related impacts, catchment level appraisal of water resource requirements reveal significant constraints in some locations. The approach and results presented in this study thus, highlights the importance of bringing together scientific understanding, data and analysis tools to provide better insights for water-energy nexus decisions at the appropriate spatial scale. This is particularly important for water stressed regions where the water-energy nexus must be analysed at appropriate spatial resolution to capture the full water resource impact of national energy policy.

    In team-based workplaces, reviewing and reflecting on the content from a previously held meeting can lead to better planning and preparation. However, ineffective meeting summaries can impair this process, especially when participants have difficulty remembering what was said and what its context was. To assist with this process, we introduce MeetingVis, a visual narrative-based approach to meeting summarization. MeetingVis is composed of two primary components: (1) a data pipeline that processes the spoken audio from a group discussion, and (2) a visual-based interface that efficiently displays the summarized content. To design MeetingVis, we create a taxonomy of relevant meeting data points, identifying salient elements to promote recall and reflection. These are mapped to an augmented storyline visualization, which combines the display of participant activities, topic evolutions, and task assignments. For evaluation, we conduct a qualitative user study with five groups. Feedback from the study indicates that MeetingVis effectively triggers the recall of subtle details from prior meetings: all study participants were able to remember new details, points, and tasks compared to an unaided, memory-only baseline. This visual-based approaches can also potentially enhance the productivity of both individuals and the whole team.

    The use of constructed wetlands for water pollution control has a long standing tradition in urban, peri-urban, rural, agricultural and mining environments. The capacity of wetland plants to take up nutrients and to filter organic matter has been widely discussed and presented in diverse fora and published in hundreds of articles. In an ever increasingly complex global world, constructed wetlands not only play a role in providing safe sanitation in decentralized settings, shelter for biodiversity, and cleansing of polluted sites, in addition, they produce biomass that can be harvested and used for the production of fodder and fuel. The United Nations University Institute for Integrated Management of Material Fluxes and of Resources (UNU-FLORES) was established in December 2012 in Dresden, Germany, to assess the trade-offs between and among resources when making sustainable decisions. Against the backdrop of the Water-Energy-Food Nexus, which was introduced as a critical element for the discussions on sustainability at Rio +20, the UNU was mandated to pay critical attention to the interconnections of the underlying resources, namely, water, soil and waste. Biomass for human consumption comes in the form of food for direct use, as fodder for livestock, and as semi-woody biomass for fuelling purposes, be it directly for heating and cooking or for the production of biogas and/or biofuel. Given the universal applicability of constructed wetlands in virtually all settings, from arid to tropical, from relatively high to low nutrient loads, and from a vast variety of pollutants, we postulate that the biomass produced in constructed wetlands can be used more extensively in order to enhance the multi-purpose use of these sites.

    Building an integrated data infrastructure that can meet the needs of a sustainable energy-water resource management requires a robust data management and geovisual analytics platform, capable of cross-domain scientific discovery and knowledge generation. Such a platform can facilitate the investigation of diverse complex research and policy questions for emerging priorities in Energy-Water Nexus (EWN) science areas. Using advanced data analytics, machine learning techniques, multi-dimensional statistical tools, and interactive geovisualization components, such a multi-layered federated platform is being developed, the Energy-Water Nexus Knowledge Discovery Framework (EWN-KDF). This platform utilizes several enterprise-grade software design concepts and standards such as extensible service-oriented architecture, open standard protocols, event-driven programming model, enterprise service bus, and adaptive user interfaces to provide a strategic value to the integrative computational and data infrastructure. EWN-KDF is built on the Compute and Data Environment for Science (CADES) environment in Oak Ridge National Laboratory (ORNL).

  1. Water-Energy Nexus: Examining The Crucial Connection Through Simulation Based Optimization

    2014-12-01

    With a growing urbanisation and the emergence of climate change, the world is facing a more water constrained future. This phenomenon will have direct impacts on the resilience and performance of energy sector as water is playing a key role in electricity generation processes. As energy is becoming a thirstier resource and the pressure on finite water sources is increasing, modelling and analysing this closely interlinked and interdependent loop, called 'water-energy nexus' is becoming an important cross-disciplinary challenge. Conflict often arises in transboundary river where several countries share the same source of water to be used in productive sectors for economic growth. From the perspective of the upstream users, it would be ideal to store the water for hydropower generation and protect the city against drought whereas the downstream users need the supply of water for growth. This research use the case study on the transboundary Blue Nile River basin located in the Middle East where the Ethiopian government decided to invest on building a new dam to store the water and generate hydropower. This leads to an opposition by downstream users as they believe that the introduction of the dam would reduce the amount of water available downstream. This calls for a compromise management where the reservoir operating rules need to be derived considering the interdependencies between the resources available and the requirements proposed by all users. For this, we link multiobjective optimization algorithm to water-energy use simulation model to achieve effective management of the transboundary reservoir operating strategies. The objective functions aim to attain social and economic welfare by minimizing the deficit of water supply and maximizing the hydropower generation. The study helps to improve the policies by understanding the value of water and energy in their alternative uses. The results show how different optimal reservoir release rules generate different

  10. Water-Energy Nexus: the case of biogas production from energy crops evaluated by Water Footprint and LCA methods

    Science.gov (United States)

    Pacetti, Tommaso; Caporali, Enrica; Federici, Giorgio

    2015-04-01

    This study analyzes the production of biogas from aerobic digestion of energy crops. The production of biogas is an important case study because its spread, similar to other sources of bioenergy, creates questions about the environmental effects, the competition in the food market as well as the progressive change of land use. In particular is hereby analyzed the nexus between bioenergy production and water, which plays a key role because water resources are often the limiting factor in energy production from energy crops. The environmental performances of biogas production were analyzed through Water Footprint (WF) and Life cycle assessment (LCA): the integration of LCA and WF represents an attempt of taking advantage of their complementary strengths in environmental assessment, trying to give a comprehensive analysis of bioenergy production sustainability. Eighteen scenarios were considered, trying to figure out the performances of different combinations of locations (north, center, south Italy), crops (maize, sorghum, wheat) and treatments (anaerobic digestion with water dilution or manure co-digestion). WF assessment shows that cultivation phase is the most impacting on water resource use along the entire system life cycle. In particular, water requirements for crop growth shows that sorghum is the more water saver crop (in terms of consumptive water use to produce the amount of crop needed to produce 1 GJ of biogas energy content). Moreover WF investigates the kind of water use and shows that wheat, despite being the most intensive water user, exploits more green water than the other crops.WF was evaluated with respect to water stress indicators for the Italian territory, underlining the higher criticalities associated with water use in southern Italy and identifying consumptive blue water use, in this area, as the main hotspot. Therefore biogas production from energy crops in southern Italy is unsustainable from a water management perspective. At a basin

  13. EDITORIAL: Nano Meets Spectroscopy Nano Meets Spectroscopy

    Birch, David J. S.

    2012-08-01

    The multidisciplinary two-day Nano Meets Spectroscopy (NMS) event was held at the National Physical Laboratory (NPL), Teddington, UK, in September 2011. The event was planned from the outset to be at the interface of several areas—in particular, spectroscopy and nanoscience, and to bring together topics and people with different approaches to achieving common goals in biomolecular science. Hence the meeting cut across traditional boundaries and brought together researchers using diverse techniques, particularly fluorescence and Raman spectroscopy. Despite engaging common problems, these techniques are frequently seen as mutually exclusive with the two communities rarely interacting at conferences. The meeting was widely seen to have lived up to its billing in good measure. It attracted the maximum capacity of ~120 participants, including 22 distinguished speakers (9 from outside the UK), over 50 posters and a vibrant corporate exhibition comprising 10 leading instrument companies and IOP Publishing. The organizers were Professor David Birch (Chair), Dr Karen Faulds and Professor Duncan Graham of the University of Strathclyde, Professor Cait MacPhee of the University of Edinburgh and Dr Alex Knight of NPL. The event was sponsored by the European Science Foundation, the Institute of Physics, the Royal Society of Chemistry, NPL and the Scottish Universities Physics Alliance. The full programme and abstracts are available at http://sensor.phys.strath.ac.uk/nms/program.php. The programme was quite ambitious in terms of the breadth and depth of scope. The interdisciplinary and synergistic concept of 'X meets Y' played well, cross-fertilization between different fields often being a source of inspiration and progress. Fluorescence and Raman spectroscopy provided the core, but the meeting had little repetition and also attracted contributions on more specialist techniques such as CARS, super-resolution, single molecule and chiral methods. In terms of application the

  3. Where Times Meet

    Directory of Open Access Journals (Sweden)

    Theodore R. Schatzki

    2005-01-01

    Full Text Available This essay pursues two goals: (1 to argue that two fundamental types of time—the time of objective reality and “the time of the soul”—meet in human activity and history and (2 to defend the legitimacy of calling a particular version of the second type a kind of time. The essay begins by criticizing Paul Ricoeur’s version of the claim that times of these two sorts meet in history. It then presents an account of human activity based on Heidegger’s Being and Time, according to which certain times of the two types—existential temporality and succession—meet in human activity. The legitimacy of calling existential temporality a kind of time is then defended via an expanded analysis of activity that examines where the two times meet there. The concluding section briefly considers a conception of historical time due to David Carr before showing why history is a broader domain encompassing human activity where the two times meet.

  5. Grounding the nexus: Examining the integration of small-scale irrigators into a national food security programme in Burkina Faso

    Directory of Open Access Journals (Sweden)

    Brian Dowd-Uribe

    2018-06-01

    Full Text Available The water-food nexus literature examines the synergies and trade-offs of resource use but is dominated by large-scale analyses that do not sufficiently engage the local dimensions of resource management. The research presented here addresses this gap with a local-scale analysis of integrated water and food management in Burkina Faso. Specifically, we analyse the implementation of a national food security campaign (Opération Bondofa to boost maize production in a subbasin that exhibits two important trends in Africa: a large increase in small-scale irrigators and the decentralisation of water management. As surface water levels dropped in the region, entities at different scales asserted increased control over water allocation, exposing the contested nature of new decentralised institutions, and powerful actors’ preference for local control. These scalar power struggles intersected with a lack of knowledge of small-scale irrigators’ cultural practices to produce an implementation and water allocation schedule that did match small-scale irrigator needs, resulting in low initial enthusiasm for the project. Increased attention from national governments to strengthen decentralised water management committees and spur greater knowledge of, and engagement with, small-scale irrigators can result in improved programme design to better incorporate small-scale irrigators into national food security campaigns.

  11. The nexus between integrated natural resources management and integrated water resources management in southern Africa

    Science.gov (United States)

    Twomlow, Stephen; Love, David; Walker, Sue

    The low productivity of smallholder farming systems and enterprises in the drier areas of the developing world can be attributed mainly to the limited resources of farming households and the application of inappropriate skills and practices that can lead to the degradation of the natural resource base. This lack of development, particularly in southern Africa, is of growing concern from both an agricultural and environmental perspective. To address this lack of progress, two development paradigms that improve land and water productivity have evolved, somewhat independently, from different scientific constituencies. One championed by the International Agricultural Research constituency is Integrated Natural Resource Management (INRM), whilst the second championed predominantly by Environmental and Civil Engineering constituencies is Integrated Water Resources Management (IWRM). As a result of similar objectives of working towards the millennium development goals of improved food security and environmental sustainability, there exists a nexus between the constituencies of the two paradigms, particularly in terms of appreciating the lessons learned. In this paper lessons are drawn from past INRM research that may have particular relevance to IWRM scientists as they re-direct their focus from blue water issues to green water issues, and vice-versa. Case studies are drawn from the management of water quality for irrigation, green water productivity and a convergence of INRM and IWRM in the management of gold panning in southern Zimbabwe. One point that is abundantly clear from both constituencies is that ‘one-size-fits-all’ or silver bullet solutions that are generally applicable for the enhancement of blue water management/formal irrigation simply do not exist for the smallholder rainfed systems.

    2005-01-01

    The objective of this study was to identify trends in academic health sciences libraries (AHSLs) as they adapt to the shift from a print knowledgebase to an increasingly digital knowledgebase. This research was funded by the 2003 David A. Kronick Traveling Fellowship. The author spent a day and a half interviewing professional staff at each library. The questionnaire used was sent to the directors of each library in advance of the visit, and the directors picked the staff to be interviewed and set up the schedule. Seven significant trends were identified. These trends are part of the shift of AHSLs from being facility and print oriented with a primary focus on their role as repositories of a print-based knowledgebase to a new focus on their role as the center or "nexus" for the organization, access, and use of an increasingly digital-based knowledgebase. This paper calls for a national effort to develop a new model or structure for health sciences libraries to more effectively respond to the challenges of access and use of a digital knowledgebase, much the same way the National Library of Medicine did in the 1960s and 1970s in developing and implementing the National Network of Libraries of Medicine. The paper then concludes with some examples or ideas for research to assist in this process.

    Climate change and drought have severe impacts on the agricultural sector affecting crop yields, water availability, and energy consumption for irrigation. Monitoring, assessing and mitigating the effects of climate change and drought on the agricultural and energy sectors are fundamental challenges that require investigation for water, food, and energy security issues. Using an integrated water-food-energy nexus approach, this study is developing a comprehensive drought management system through integration of real-time drought monitoring with real-time irrigation management. The spatially explicit model developed, GIS-OptiCE, can be used for simulation, multi-criteria optimization and generation of forecasts to support irrigation management. To demonstrate the value of the approach, the model has been applied to one major corn region in Nebraska to study the effects of the 2012 drought on crop yield and irrigation water/energy requirements as compared to a wet year such as 2009. The water-food-energy interrelationships evaluated show that significant water volumes and energy are required to halt the negative effects of drought on the crop yield. The multi-criteria optimization problem applied in this study indicates that the optimal solutions of irrigation do not necessarily correspond to those that would produce the maximum crop yields, depending on both water and economic constraints. In particular, crop pricing forecasts are extremely important to define the optimal irrigation management strategy. The model developed shows great potential in precision agriculture by providing near real-time data products including information on evapotranspiration, irrigation volumes, energy requirements, predicted crop growth, and nutrient requirements.

  15. An Interval Fuzzy-Stochastic Chance-Constrained Programming Based Energy-Water Nexus Model for Planning Electric Power Systems

    Full Text Available In this study, an interval fuzzy-stochastic chance-constrained programming based energy-water nexus (IFSCP-WEN model is developed for planning electric power system (EPS. The IFSCP-WEN model can tackle uncertainties expressed as possibility and probability distributions, as well as interval values. Different credibility (i.e., γ levels and probability (i.e., qi levels are set to reflect relationships among water supply, electricity generation, system cost, and constraint-violation risk. Results reveal that different γ and qi levels can lead to a changed system cost, imported electricity, electricity generation, and water supply. Results also disclose that the study EPS would tend to the transition from coal-dominated into clean energy-dominated. Gas-fired would be the main electric utility to supply electricity at the end of the planning horizon, occupying [28.47, 30.34]% (where 28.47% and 30.34% present the lower bound and the upper bound of interval value, respectively of the total electricity generation. Correspondingly, water allocated to gas-fired would reach the highest, occupying [33.92, 34.72]% of total water supply. Surface water would be the main water source, accounting for more than [40.96, 43.44]% of the total water supply. The ratio of recycled water to total water supply would increase by about [11.37, 14.85]%. Results of the IFSCP-WEN model present its potential for sustainable EPS planning by co-optimizing energy and water resources.

    Demand for water in the GCC countries relies mainly on fossil groundwater resources and desalination. Satisfying water demand requires a great deal of energy as it treats and moves water along the supply chain from sources, through treatment processes, and ultimately to the consumer. Hence, there is an inherent connection between water and energy and with climate change, the links between water and energy are expected to become even stronger. As part of AGEDI's Local, National, and Regional Climate Change Programme, a study of the water-energy nexus of the countries in the Arabian Peninsula was implemented. For water, WEAP models both water demand - and its main drivers - and water supply, simulating policies, priorities and preferences. For energy, LEAP models both energy supply and demand, and is able to capture the impacts of low carbon development strategies. A coupled WEAP-LEAP model was then used to evaluate the future performance of the energy-water system under climate change and policy scenarios. The coupled models required detailed data, which were obtained through literature reviews and consultations with key stakeholders in the region. As part of this process, the outputs of both models were validated for historic periods using existing data The models examined 5 policy scenarios of different futures of resource management to the year 2060. A future under current management practices with current climate and a climate projection based on the RCP8.5; a High Efficiency scenario where each country gradually implements policies to reduce the consumption of water and electricity; a Natural Resource Protection scenario with resource efficiency and phasing out of groundwater extraction and drastic reduction of fossil fuel usage in favor of solar; and an Integrated Policy scenario that integrates the prior two policy scenarios Water demands can mostly be met in any scenario through supply combinations of groundwater, desalination and wastewater reuse, with some

  18. Users’ Encounter With Normative Discourses on Facebook: A Three-Pronged Analysis of User Agency as Power Structure, Nexus, and Reception

    Directory of Open Access Journals (Sweden)

    David Mathieu

    2016-12-01

    Full Text Available This study asks whether users’ encounter with normative discourses of lifestyle, consumption, and health on social media such as Facebook gives rise to agency. The theoretical framework draws on reception analysis, for its implied, but central interest in agency that lies at the intersection of texts and audiences. Based on a critique of the “participatory paradigm,” a paradigm that situates the locus of agency in the structural opposition between senders and users, in the norms of rational deliberation or in the figure of the activist, gaps are identified which can be filled by adopting an explicit focus on the socio-cultural practices of ordinary audiences in their encounters with media discourses. The study investigates user agency on seven Facebook groups and pages with the help of a three-pronged perspective based on the notion of the media–audience relationship as (1 power structure, (2 nexus, and (3 reception. The analysis reveals that the structure at play on these Facebook groups and pages does not encourage user agency. However, user agency manifests itself through user interactions and expressive sense-making processes associated with reception. The benefits of such audience agency are a public, collective, and communicative sense-making process and an expansion of the professionally controlled text.

    The first Transgenic Technology (TT) Meeting was organized in 1999 by Johannes Wilbertz, Karolinska Institute, Stockholm, Sweden as a regional meeting. The TT Meetings continued in this way, constantly gathering additional practitioners of transgenic methodologies until the breakthrough in 2005 when the 6th TT Meeting in Barcelona, Spain, hosted by Lluis Montoliu (Centro Nacional de Biotecnologia, Madrid, Spain), generated the momentum to establish the International Society for Transgenic Technologies (ISTT). Since 2006, the ISTT has continued to promote the TT Meetings and provide its membership with a forum to discuss best practices and new methods in the field. The TT2010 Meeting was held at the Max Delbrück Center for Molecular Medicine (Berlin, Germany). Participation at the TT2010 Meeting exceeded the registration capacity and set a new attendance record. Session topics included methods for the generation of rat and mouse models of human disease, fundamental and advanced topics in rodent embryonic stem cells, and the newest transgenic technologies. Short presentations from selected abstracts were of especial interest. Roundtable discussions on transgenic facility establishment and cryoarchiving of mouse lines were favorably received. Students, technical staff, and professors participated in numerous discussions and came away with practical methods and new ideas for research.

    The ability to skillfully lead meetings can contribute to a manager's effectiveness. There are four types of meetings, each serving different needs and requiring different leadership. A manager must know when to hold meetings, what leadership style is appropriate, how and when to use participative management, and how to facilitate a consensus. Considerable planning must be done before a meeting is held. Various leadership and communication skills are required to effectively open, conduct, and close a meeting. Finally, the leader needs to know how to deal with participants who become problems.
