  5. Integrated water resources modelling for assessing sustainable water governance (United States)

    Skoulikaris, Charalampos; Ganoulis, Jacques; Tsoukalas, Ioannis; Makropoulos, Christos; Gkatzogianni, Eleni; Michas, Spyros


    Climatic variations and resulting future uncertainties, increasing anthropogenic pressures, changes in political boundaries, ineffective or dysfunctional governance of natural resources and environmental degradation are some of the most fundamental challenges with which worldwide initiatives fostering the "think globally, act locally" concept are concerned. Different initiatives target the protection of the environment through sustainable development; Integrated Water Resources Management (IWRM) and Transboundary Water Resources Management (TWRM) in the case of internationally shared waters are frameworks that have gained wide political acceptance at international level and form part of water resources management planning and implementation on a global scale. Both concepts contribute in promoting economic efficiency, social equity and environmental sustainability. Inspired by these holistic management approaches, the present work describes an effort that uses integrated water resources modelling for the development of an integrated, coherent and flexible water governance tool. This work in which a sequence of computer based models and tools are linked together, aims at the evaluation of the sustainable operation of projects generating renewable energy from water as well as the sustainability of agricultural demands and environmental security in terms of environmental flow under various climatic and operational conditions. More specifically, catchment hydrological modelling is coupled with dams' simulation models and thereafter with models dedicated to water resources management and planning,while the bridging of models is conducted through geographic information systems and custom programming tools. For the case of Mesta/Nestos river basin different priority rules in the dams' operational schedule (e.g. priority given to power production as opposed to irrigation needs and vice versa), as well as different irrigation demands, e.g. current water demands as opposed to

  6. A review on water pricing problem for sustainable water resource (United States)

    Hek, Tan Kim; Ramli, Mohammad Fadzli; Iryanto


    A report that presented at the World Forum II at The Hague in March 2000, said that it would be water crisis around the world and some countries will be lack of water in 2025, as a result of global studies. Inefficient using of water and considering water as free goods which means it can be used as much as we want without any lost. Thus, it causes wasteful consumption and low public awareness in using water without effort to preserve and conserve the water resources. In addition, the excessive exploitation of ground water for industrial facilities also leads to declining of available freshwater. Therefore, this paper reviews some problems arise all over the world regarding to improper and improving management, policies and methods to determine the optimum model of freshwater price in order to avoid its wasteful thus ensuring its sustainability. In this paper, we also proposed a preliminary model of water pricing represents a case of Medan, North Sumatera, Indonesia.

  7. Sustainability assessment of regional water resources under the DPSIR framework (United States)

    Sun, Shikun; Wang, Yubao; Liu, Jing; Cai, Huanjie; Wu, Pute; Geng, Qingling; Xu, Lijun


    Fresh water is a scarce and critical resource in both natural and socioeconomic systems. Increasing populations combined with an increasing demand for water resources have led to water shortages worldwide. Current water management strategies may not be sustainable, and comprehensive action should be taken to minimize the water budget deficit. Sustainable water resources management is essential because it ensures the integration of social, economic, and environmental issues into all stages of water resources management. This paper establishes the indicators to evaluate the sustainability of water utilization based on the Drive-Pressure-Status-Impact-Response (DPSIR) model. Based on the analytic hierarchy process (AHP) method, a comprehensive assessment of changes to the sustainability of the water resource system in the city of Bayannur was conducted using these indicators. The results indicate that there is an increase in the driving force of local water consumption due to changes in society, economic development, and the consumption structure of residents. The pressure on the water system increased, whereas the status of the water resources continued to decrease over the study period due to the increasing drive indicators. The local government adopted a series of response measures to relieve the decreasing water resources and alleviate the negative effects of the increasing driver in demand. The response measures improved the efficiency of water usage to a large extent, but the large-scale expansion in demands brought a rebounding effect, known as ;Jevons paradox; At the same time, the increasing emissions of industrial and agriculture pollutants brought huge pressures to the regional water resources environment, which caused a decrease in the sustainability of regional water resources. Changing medium and short-term factors, such as regional economic pattern, technological levels, and water utilization practices, can contribute to the sustainable utilization of

  11. The Sparta Aquifer: A Sustainable Water Resource? (United States)

    McKee, Paul W.; Hays, Phillip D.


    Introduction The Sparta aquifer is an aquifer of regional importance within the Mississippi embayment aquifer system. It consists of varying amounts of unconsolidated sand, inter-stratified with silt and clay lenses within the Sparta Sand of the Claiborne Group. It extends from south Texas, north into Louisiana, Arkansas, and Tennessee, and eastward into Mississippi and Alabama (fig. 1). On both the west and east sides of the Mississippi embayment, the Sparta aquifer is exposed at the surface (outcrops) and is locally unconfined; it becomes confined as it dips toward the axis of the embayment, (generally corresponding with the Mississippi River) and southward toward the Gulf of Mexico where it is deeply buried in the subsurface (Hosman, 1968). Generalized ground-water flow in the Sparta aquifer is from the outcrop areas to the axis (center) of the embayment (fig. 2). In Arkansas, the Sparta aquifer outcrops parallel to the Fall Line at the western extreme of the Mississippi embayment (the Fall Line is a line dividing the mountainous highlands of Arkansas from the lowland area); and the formation dips from its outcrop area to the southeast. The Sparta aquifer supplies water for municipalities, industries such as paper production, and to a lesser degree, irrigation of agricultural crops (fig. 3). This report highlights hydrologic conditions of the aquifer in Arkansas County as an example of how water use is affecting water levels.

  12. Diversification of the resources of the Parisian water network : contribution to sustainable management of water resources


    Trinh, Bich-Thuy


    At the scale of a city, a sustainable water management raises questions about the links between uses and resources: what water quality is needed for what purpose? The Parisian context is a favourable ground for conducting such type of reflection thanks to the existence of a non-potable water network (RENP) dating from the late nineteenth century. The network is currently supplied by summarily filtrated water from the Seine river (20%) and the canal de l’Ourcql (80%). It is mainly used for mun...

  13. Framework for Assessing Water Resource Sustainability in River Basins (United States)

    Borden, J.; Goodwin, P.; Swanson, D.


    As the anthropogenic footprint increases on Earth, the wise use, maintenance, and protection of freshwater resources will be a key element in the sustainability of development. Borne from efforts to promote sustainable development of water resources is Integrated Water Resource Management (IWRM), which promotes efficiency of water resources, equity in water allocation across different social and economic groups, and environmental sustainability. Methodologies supporting IWRM implementation have largely focused on the overall process, but have had limited attention on the evaluation methods for ecologic, economic, and social conditions (the sustainability criterion). Thus, assessment frameworks are needed to support the analysis of water resources and evaluation of sustainable solutions in the IWRM process. To address this need, the River Basin Analysis Framework (RBAF) provides a structure for understanding water related issues and testing the sustainability of proposed solutions in river basins. The RBAF merges three approaches: the UN GEO 4 DPSIR approach, the Millennium Ecosystem Assessment approach, and the principles of sustainable development. Merging these approaches enables users to understand the spatiotemporal interactions between the hydrologic and ecologic systems, evaluate the impacts of disturbances (drivers, pressures) on the ecosystem goods and services (EGS) and constituents of human well-being (HWB), and identify and employ analytical methods and indicators in the assessments. The RBAF is comprised of a conceptual component (RBAF-C) and an analytical component (RBAF-A). For each disturbance type, the RBAF-C shows the potential directional change in the hydrologic cycle (peak flows, seasonality, etc.), EGS (drinking water supply, water purification, recreational opportunities, etc.), and HWB (safety, health, access to a basic materials), thus allowing users insight into potential impacts as well as providing technical guidance on the methods and

  14. Practices and perceptions on water resource sustainability in ecovillages (United States)

    de Moura Leite, Flavia Brunale Vilela; Bertolo, Lídia Sanches; Santos, Rozely Ferreira


    In many areas of the world, groups of people have attempted to create urban landscapes that follow the principles of environmental sustainability. To this end, groups have devised alternative models, such as ecovillages, where low-impact handling is used and a way of life different from that of large population centers is adopted. Although these villages exist, their efficiency in the conservation of natural resources has not been effectively evaluated. This study evaluated the practices used by two Brazilian ecovillages to conserve water resources to assess whether this new concept of living is indeed successful in meeting sustainability goals. We selected 25 indicators of water sustainability, and using the compromise programming method, we quantified the distance between those landscapes self-referenced as sustainable and an ideal hypothetical scenario. We also interpreted the communities perceptions using the distance between the current situations and the envisioned scenario. We concluded that both ecovillage are far from technically ideal scenario, but the communities have a strong sense of their limitations in implementing water resources conservation. The communities attributed this fact primarily to deficiencies in the shared management.

  15. Roadmap for sustainable water resources in southwestern North America (United States)

    Gleick, Peter H.


    The management of water resources in arid and semiarid areas has long been a challenge, from ancient Mesopotamia to the modern southwestern United States. As our understanding of the hydrological and climatological cycles has improved, and our ability to manipulate the hydrologic cycle has increased, so too have the challenges associated with managing a limited natural resource for a growing population. Modern civilization has made remarkable progress in water management in the past few centuries. Burgeoning cities now survive in desert regions, relying on a mix of simple and complex technologies and management systems to bring adequate water and remove wastewater. These systems have permitted agricultural production and urban concentrations to expand in regions previously thought to have inadequate moisture. However, evidence is also mounting that our current management and use of water is unsustainable. Physical, economic, and ecological limits constrain the development of new supplies and additional water withdrawals, even in regions not previously thought vulnerable to water constraints. New kinds of limits are forcing water managers and policy makers to rethink previous assumptions about population, technology, regional planning, and forms of development. In addition, new threats, especially the challenges posed by climatic changes, are now apparent. Sustainably managing and using water in arid and semiarid regions such as the southwestern United States will require new thinking about water in an interdisciplinary and integrated way. The good news is that a wide range of options suggest a roadmap for sustainable water management and use in the coming decades. PMID:21149725

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

    Directory of Open Access Journals (Sweden)

    Ge Sun


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

  17. Using Case Studies to Teach Interdisciplinary Water Resource Sustainability (United States)

    Orr, C. H.; Tillotson, K.


    Teaching about water resources and often emphasizes the biophysical sciences to understand highly complex hydrologic, ecologic and engineering systems, yet most impediments to improving management emerge from social processes. Challenges to more sustainable management often result from trade-offs among stakeholders (e.g., ecosystem services, energy, municipal use, and agriculture) and occur while allocating resources to competing goals of economic development, social equity, and efficient governance. Competing interests operating across multiple scales can increase tensions and prevent collaborative resolution of resource management problems. Here we discuss using specific, place-based cases to teach the interdisciplinary context of water management. Using a case approach allows instructors to first explore the geologic and hydrologic setting of a specific problem to let students understand where water comes from, then how it is used by people and ecosystems, and finally what conflicts arise from mismatches between water quality, quantity, timing, human demand, and ecosystem needs. The case approach helps students focus on specific problem to understand how the landscape influences water availability, without needing to first learn everything about the relevant fields. We look at geology, hydrology and climate in specific watersheds before addressing the human and ecosystem aspects of the broader, integrated system. This gives students the context to understand what limits water availability and how a water budget constrains possible solutions to sustainability problems. It also mimics the approach we have taken in research addressing these problems. In an example case the Spokane Coeur D'Alene basin, spanning the border between SE Washington and NW Idaho, includes a sole source aquifer system with high exchange between surface water and a highly conductive aquifer. The Spokane River does not meet water quality standards and is likely to face climate driven shifts

  18. Scenario analysis for sustainable development of Chongming Island: water resources sustainability. (United States)

    Ni, Xiong; Wu, Yanqing; Wu, Jun; Lu, Jian; Wilson, P Chris


    With the socioeconomic and urban development of Chongming Island (the largest alluvial island in the world), water demand is rapidly growing. To make adjustments to the water utilization structure of each industry, allocate limited water resources, and increase local water use efficiency, this study performed a scenario analysis for the water sustainability of Chongming Island. Four different scenarios were performed to assess the water resource availability by 2020. The growth rate for water demand will be much higher than that of water supply under a serious situation prediction. The water supply growth volume will be 2.22 × 10(8)m(3) from 2010 to 2020 under Scenario I and Scenario II while the corresponding water demand growth volume will be 2.74 × 10(8)m(3) and 2.64 × 10(8)m(3), respectively. There will be a rapid growth in water use benefit under both high and low development modes. The water use benefit will be about 50 CNY/m(3) under Scenarios I and II in 2020. The production structure will need to be adjusted for sustainable utilization of water resources. Sewage drainage but not the forest and grass coverage rate will be a major obstacle to future development and environmental quality. According to a multi-level fuzzy comprehensive evaluation, Scenario II is finally deemed to be the most desirable plan, suggesting that the policy of rapid socioeconomic development and better environmental protection may achieve the most sustainable development of Chongming Island in the future.

  19. Sustainability Assessment of indicators for integrated water resources management. (United States)

    Pires, A; Morato, J; Peixoto, H; Botero, V; Zuluaga, L; Figueroa, A


    The scientific community strongly recommends the adoption of indicators for the evaluation and monitoring of progress towards sustainable development. Furthermore, international organizations consider that indicators are powerful decision-making tools. Nevertheless, the quality and reliability of the indicators depends on the application of adequate and appropriate criteria to assess them. The general objective of this study was to evaluate how indicators related to water use and management perform against a set of sustainability criteria. Our research identified 170 indicators related to water use and management. These indicators were assessed by an international panel of experts that evaluated whether they fulfil the four sustainability criteria: social, economic, environmental, and institutional. We employed an evaluation matrix that classified all indicators according to the DPSIR (Driving Forces, Pressures, States, Impacts and Responses) framework. A pilot study served to test and approve the research methodology before carrying out the full implementation. The findings of the study show that 24 indicators comply with the majority of the sustainability criteria; 59 indicators are bi-dimensional (meaning that they comply with two sustainability criteria); 86 are one-dimensional indicators (fulfilling just one of the four sustainability criteria) and one indicator do not fulfil any of the sustainability criteria.

  1. Regulation of water resources for sustaining global future socioeconomic development (United States)

    Chen, J.; SHI, H.; Sivakumar, B.


    With population projections indicating continued growth during this century, socio-economic problems (e.g., water, food, and energy shortages) will be most likely to occur, especially if proper planning, development, and management strategies are not adopted. In the present study, firstly, we explore the vital role of dams in promoting economic growth through analyzing the relationship between dams and Gross Domestic Product (GDP) at both global and national scales. Secondly, we analyze the current situation of global water scarcity based on the data representing water resources availability, dam development, and the level of economic development. Third, with comprehensive consideration of population growth as the major driving force, water resources availability as the basic supporting factor, and topography as the important constraint, this study addresses the question of dam development in the future and predicts the locations of future dams around the world.

  2. Environmental sustainability control by water resources carrying capacity concept: application significance in Indonesia (United States)

    Djuwansyah, M. R.


    This paper reviews the use of Water Resources carrying capacity concept to control environmental sustainability with the particular note for the case in Indonesia. Carrying capacity is a capability measure of an environment or an area to support human and the other lives as well as their activities in a sustainable manner. Recurrently water-related hazards and environmental problems indicate that the environments are exploited over its carrying capacity. Environmental carrying capacity (ECC) assessment includes Land and Water Carrying Capacity analysis of an area, suggested to always refer to the dimension of the related watershed as an incorporated hydrologic unit on the basis of resources availability estimation. Many countries use this measure to forecast the future sustainability of regional development based on water availability. Direct water Resource Carrying Capacity (WRCC) assessment involves population number determination together with their activities could be supported by available water, whereas indirect WRCC assessment comprises the analysis of supply-demand balance status of water. Water resource limits primarily environmental carrying capacity rather than the land resource since land capability constraints are easier. WRCC is a crucial factor known to control land and water resource utilization, particularly in a growing densely populated area. Even though capability of water resources is relatively perpetual, the utilization pattern of these resources may change by socio-economic and cultural technology level of the users, because of which WRCC should be evaluated periodically to maintain usage sustainability of water resource and environment.

  3. Engaging Southwestern Tribes in Sustainable Water Resources Topics and Management

    Directory of Open Access Journals (Sweden)

    Karletta Chief


    Full Text Available Indigenous peoples in North America have a long history of understanding their societies as having an intimate relationship with their physical environments. Their cultures, traditions, and identities are based on the ecosystems and sacred places that shape their world. Their respect for their ancestors and ‘Mother Earth’ speaks of unique value and knowledge systems different than the value and knowledge systems of the dominant United States settler society. The value and knowledge systems of each indigenous and non-indigenous community are different but collide when water resources are endangered. One of the challenges that face indigenous people regarding the management of water relates to their opposition to the commodification of water for availability to select individuals. External researchers seeking to work with indigenous peoples on water research or management must learn how to design research or water management projects that respect indigenous cultural contexts, histories of interactions with settler governments and researchers, and the current socio-economic and political situations in which indigenous peoples are embedded. They should pay particular attention to the process of collaborating on water resource topics and management with and among indigenous communities while integrating Western and indigenous sciences in ways that are beneficial to both knowledge systems. The objectives of this paper are to (1 to provide an overview of the context of current indigenous water management issues, especially for the U.S. federally recognized tribes in the Southwestern United States; (2 to synthesize approaches to engage indigenous persons, communities, and governments on water resources topics and management; and (3 to compare the successes of engaging Southwestern tribes in five examples to highlight some significant activities for collaborating with tribes on water resources research and management. In discussing the engagement

  5. Water resource management for sustainable agriculture in Punjab, India. (United States)

    Aggarwal, Rajan; Kaushal, Mohinder; Kaur, Samanpreet; Farmaha, Bhupinder


    The state of Punjab comprising 1.5% area of the country has been contributing 40-50% rice and 60-65% wheat to the central pool since last three decades. During last 35 years The area under foodgrains has increased from 39,200 sq km ha to 63,400 sq km and the production of rice and wheat has increased from 0.18 to 0.32 kg/m2 and 0.22 to 0.43 kg/m2 respectively. This change in cropping pattern has increased irrigation water requirement tremendously and the irrigated area has increased from 71 to 95% in the state. Also the number of tube wells has increased from 0.192 to 1.165 million in the last 35 years. The excessive indiscriminate exploitation of ground water has created a declining water table situation in the state. The problem is most critical in central Punjab. The average rate of decline over the last few years has been 55 cm per year. The worst affected districts are Moga, Sangrur, Nawanshahar, Ludhiana and Jalandhar. This has resulted in extra power consumption, affects the socio-economic conditions of the small farmers, destroy the ecological balance and adversely affect the sustainable agricultural production and economy of the state. Therefore, in this paper attempt has been made to analyse the problem of declining water table, possible factors responsible for this and suggest suitable strategies for arresting declining water table for sustainable agriculture in Punjab. The strategies include shift of cropping pattern, delay in paddy transplantation, precision irrigation and rainwater harvesting for artificial groundwater recharge.

  10. Sustainable Water and Agricultural Land Use in the Guanting Watershed under Limited Water Resources (United States)

    Wechsung, F.; Möhring, J.; Otto, I. M.; Wang, X.; Guanting Project Team


    The Yongding River System is an important water source for the northeastern Chinese provinces Shanxi, Hebei, Beijing, and Tianjin. The Guanting Reservoir within this river system is one of the major water sources for Beijing, which is about 70 km away. Original planning assumed a discharge of 44 m3/s for the reservoir, but the current mean discharge rate is only about 5 m3/s; there is often hardly any discharge at all. Water scarcity is a major threat for the socio-economic development of the area. The situation is additionally aggravated by climate change impacts. Typical upstream-downstream conflicts with respect to water quantity and quality requests are mixed up with conflicts between different sectors, mainly mining, industry, and agriculture. These conflicts can be observed on different administrative levels, for example between the provinces, down to households. The German-Chinese research project "Sustainable water and agricultural land use in the Guanting Watershed under limited water resources" investigates problems and solutions related to water scarcity in the Guanting Catchment. The aim of the project is to create a vulnerability study in order to assess options for (and finally achieve) sustainable water and land use management in the Guanting region. This includes a comprehensive characterization of the current state by gap analysis and identification of pressures and impacts. The presentation gives an overview of recent project results regarding regionalization of global change scenarios and specification for water supply, evaluation of surface water quantity balances (supply-demand), evaluation of the surface water quality balances (emissions-impact thresholds), and exploration of integrative measurement planning. The first results show that climate in the area is becoming warmer and drier which leads to even more dramatically shrinking water resources. Water supply is expected to be reduced between one and two thirds. Water demand might be

  12. Strengthening Sustainable Water Resources Adaptive Capacity To Climate Change, A Case Study in Taiwan (United States)

    Tung, C.; Chen, S.; Liu, T.; Yu, P.


    Climate change refers to the long-term variation, which may exacerbate short-term climate variability and more extreme events, and then may impact on human society and natural environment. Socioeconomic development is dependent on adequate water resources, but climate change may impact on such supply system, including available streamflow, groundwater, irrigation requirement and also impact on the sustainability for regional water alimentation. The purposes of this study are to assess the climate change impacts on regional water supply systems and to propose response strategies strengthening adaptive capacity to achieve sustainable water uses. To simulate the processes of surface water, a physical model, Hydrologiska Byråns Vattenbalansavdelning (HBV) model, is used. A system dynamics approach using a specialized software tool, Vensim, is used to simulate a water supply system of the Danshuei river watershed in Taiwan to analyze the climate impacts on sustainable water resource utilization. In order to understand the improvement of adaptive capacity for all response strategies, adjusting parameters on a system dynamics model and a definition of a sustainable index is necessary to recognize the benefits of every response strategy. To make the adaptive strategies practical, the selection of adaptive strategies according to the governmental plan such as re-allocation of regional water resources and increase of water supply capacity will be discussed in the end. Hopefully, the adaptive capacity will be enhanced to mitigate climate change impacts on water supply system to achieve sustainable water uses.

  16. Deficit irrigation and sustainable water-resource strategies in agriculture for China's food security. (United States)

    Du, Taisheng; Kang, Shaozhong; Zhang, Jianhua; Davies, William J


    More than 70% of fresh water is used in agriculture in many parts of the world, but competition for domestic and industrial water use is intense. For future global food security, water use in agriculture must become sustainable. Agricultural water-use efficiency and water productivity can be improved at different points from the stomatal to the regional scale. A promising approach is the use of deficit irrigation, which can both save water and induce plant physiological regulations such as stomatal opening and reproductive and vegetative growth. At the scales of the irrigation district, the catchment, and the region, there can be many other components to a sustainable water-resources strategy. There is much interest in whether crop water use can be regulated as a function of understanding of physiological responses. If this is the case, then agricultural water resources can be reallocated to the benefit of the broader community. We summarize the extent of use and impact of deficit irrigation within China. A sustainable strategy for allocation of agricultural water resources for food security is proposed. Our intention is to build an integrative system to control crop water use during different cropping stages and actively regulate the plant's growth, productivity, and development based on physiological responses. This is done with a view to improving the allocation of limited agricultural water resources. © The Author 2015.

  18. An evaluation method of the sustainability of water resource in karst region: a case study of Zunyi, China (United States)

    Li, Bo; Wang, Ganlu; Ding, Hanghang; Chen, Yulong


    Water resource is of great significance to the survival and development of human. However, the water resource system in karst regions is sensitive to external interference owing to the special geological processes which cause soil impoverishment, severe rocky desertification and large topographic height difference. Therefore, evaluating the sustainability of the water resource in karst regions is beneficial to reasonably use and protect water resource. This paper puts forward to evaluate the water resource from four aspects, including water resources system, water requirement system, ecosystem and social economic system. Moreover, on this basis, 18 evaluation indexes were selected to construct the sustainability evaluation index system and method. This method was used to evaluate the sustainability of the water resource in the typical karst region—Zunyi, Guizhou province, China, and was verified according to the actual situation in the research area. All these provide reference for the evaluation of the sustainability of the water resource in similar regions.

  20. Method selection for sustainability assessments: The case of recovery of resources from waste water. (United States)

    Zijp, M C; Waaijers-van der Loop, S L; Heijungs, R; Broeren, M L M; Peeters, R; Van Nieuwenhuijzen, A; Shen, L; Heugens, E H W; Posthuma, L


    Sustainability assessments provide scientific support in decision procedures towards sustainable solutions. However, in order to contribute in identifying and choosing sustainable solutions, the sustainability assessment has to fit the decision context. Two complicating factors exist. First, different stakeholders tend to have different views on what a sustainability assessment should encompass. Second, a plethora of sustainability assessment methods exist, due to the multi-dimensional characteristic of the concept. Different methods provide other representations of sustainability. Based on a literature review, we present a protocol to facilitate method selection together with stakeholders. The protocol guides the exploration of i) the decision context, ii) the different views of stakeholders and iii) the selection of pertinent assessment methods. In addition, we present an online tool for method selection. This tool identifies assessment methods that meet the specifications obtained with the protocol, and currently contains characteristics of 30 sustainability assessment methods. The utility of the protocol and the tool are tested in a case study on the recovery of resources from domestic waste water. In several iterations, a combination of methods was selected, followed by execution of the selected sustainability assessment methods. The assessment results can be used in the first phase of the decision procedure that leads to a strategic choice for sustainable resource recovery from waste water in the Netherlands.

  1. Interactions of Woody Biofuel Feedstock Production Systems with Water Resources: Considerations for Sustainability

    Energy Technology Data Exchange (ETDEWEB)

    Trettin, Carl C. [US Forest Service Center for Forested Wetlands Research, Cordesville, SC (United States); Amatya, Devendra [US Forest Service Center for Forested Wetlands Research, Cordesville, SC (United States); Coleman, Mark [US Forest Service Center for Forested Wetlands Research, Cordesville, SC (United States)


    Water resources are important for the production of woody biofuel feedstocks. It is necessary to ensure that production systems do not adversely affect the quantity or quality of surface and ground water. The effects of woody biomass plantations on water resources are largely dependent on the prior land use and the management regime. Experience from both irrigated and non-irrigated systems has demonstrated that woody biofuel production systems do not impair water quality. Water quality actually improves from conversion of idle or degraded agricultural lands to woody biomass plantations. Site water balance may be altered by cultivation of woody biomass plantations relative to agricultural use, due to increases in evapostranspiration (ET) and storage. Incorporation of woody biomass production plantations within the landscape provides an opportunity to improve the quality of runoff water and soil conservation. Finally, given the centrality of water resources to the sustainability of ecosystem services and other values derived, the experience with woody biofuels feedstock production systems is positive.

    Brown, Casey M.; Lund, Jay R.; Cai, Ximing; Reed, Patrick M.; Zagona, Edith A.; Ostfeld, Avi; Hall, Jim; Characklis, Gregory W.; Yu, Winston; Brekke, Levi


    This paper presents a short history of water resources systems analysis from its beginnings in the Harvard Water Program, through its continuing evolution toward a general field of water resources systems science. Current systems analysis practice is widespread and addresses the most challenging water issues of our times, including water scarcity and drought, climate change, providing water for food and energy production, decision making amid competing objectives, and bringing economic incentives to bear on water use. The emergence of public recognition and concern for the state of water resources provides an opportune moment for the field to reorient to meet the complex, interdependent, interdisciplinary, and global nature of today's water challenges. At present, water resources systems analysis is limited by low scientific and academic visibility relative to its influence in practice and bridled by localized findings that are difficult to generalize. The evident success of water resource systems analysis in practice (which is set out in this paper) needs in future to be strengthened by substantiating the field as the science of water resources that seeks to predict the water resources variables and outcomes that are important to governments, industries, and the public the world over. Doing so promotes the scientific credibility of the field, provides understanding of the state of water resources and furnishes the basis for predicting the impacts of our water choices.

  4. Study benefit value of utilization water resources for energy and sustainable environment (United States)

    Juniah, Restu; Sastradinata, Marwan


    Referring to the concept of sustainable development, the environment is said to be sustainable if the fulfillment of three pillars of development that is economic, social and ecological or the environment itself. The environment can sustained in the principle of ecology or basic principles of environmental science, when the three environmental components, namely the natural environment, the artificial environment (the built environment) and the social environment can be aligned for sustainability. The natural environment in this study is the water resources, the artificial environment is micro hydroelectric power generation (MHPG), and the social environment is the community living around the MHPG. The existence of MHPG is intended for the sustainability of special electrical energy for areas not yet reached by electricity derived from the state electricity company (SEC). The utilization of MHPG Singalaga in South Ogan Komering Ulu (OKUS) district is not only intended for economic, ecological, and social sustainability in Southern OKU district especially those who live in Singalaga Village, Kisam Tinggi District. This paper discusses the economic, ecological and social benefits of water resources utilization in Southern OKU District for MHPG Singalaga. The direct economic benefits that arise for people living around MHPG Singalaga is the cost incurred by the community for the use of electricity is less than if the community uses electricity coming from outside the MHPG. The cost to society in the form of dues amounting to IDR 15,000 a month / household. Social benefits with the absorption of manpower to manage the MHPG is chairman, secretary and 3 members, while the ecological benefits of water resources and sustainable energy as well as the community while maintaining the natural vegetation that is located around the MHPG for the continuity of water resources.

    Giorgio Ghiglieri


    Full Text Available Sustainable water management plays an important role in the frame of the multidisciplinary research activities aiming to combat or to mitigate the desertification processes. The study activities have been carried out by RIADE Research Project (Integrated Research for Applying new technologies and processes for combating Desertification, RIADE was co-financed by MIUR within the National Operative Programme 2000-2006. The primary objective was to explore and to develop models and strategies for innovative and sustainable solutions of water resources management, adopting a multidisciplinary approach, at the catchment and hydrogeological basin scale in a Mediterranean context, using a case history of a pilot area in NW Sardinia (Italy. The high concentration of population in this coastal zone and the intense agricultural activity have determined a relevant increase of water demand. This demand is generally satisfied by surface water, but, in some peculiar dry periods, it exceeds the available quantities. In these critical periods, groundwater are the only alternative source constituting a strategic water resource. The groundwater chemical properties are then correlated with the effects of the anthropogenic pressures. The used approach shows the application of groundwater protection criteria, in accordance with EU policies, and it was aimed to develop a methodological tool which can be applied to different scenarios.

  7. Water resources and the historic wells of Barbuda: tradition, heritage and hope for a sustainable future

    Directory of Open Access Journals (Sweden)

    Rebecca Boger


    Full Text Available The island of Barbuda has a relatively unique history, land tenure and geography. Unlike its Caribbean counterparts, the island is not suited to large-scale agriculture due to its arid climate and relatively thin soils. Instead, the enslaved and eventually free people of Barbuda developed a complex herding ecology centered on common land ownership. As a result, carefully designed historic wells are strategically located around the island. With the challenges brought about by climate change, an interdisciplinary, international team led by the Barbuda Research Complex is investigating the state of existing water and food resources and examining how the availability and quality of water resources have influenced local cultural practices. Barbudans and international scientists are working together to improve their resilience and live more sustainably in this new era of climatic adversity.

  9. Sustainability of Water Resources in Arid Ecosystems: A View from Hei River Basin, China (Invited) (United States)

    Zheng, C.; Cheng, G.; Xiao, H.; Ma, R.


    The northwest of China is characterized by an arid climate and fragile ecosystems. With irrigated agriculture, the region is a prolific producer of cotton, wheat, and maize with some of the highest output per acre in the country. The region is also rich in ore deposits, with the reserves of numerous minerals ranked at or near the top in the country. However, the sustainability of irrigated agriculture and economic development in the region is threaten by severe eco-environmental problems resulting from both global changes and human activities, such as desertification, salinization, groundwater depletion, and dust storms. All these problems are a direct consequence of water scarcity. As global warming accelerates and rapid economic growth continues, the water shortage crisis is expected to worsen. To improve the bleak outlook for the health of ecosystem and environment in northwest China, the Chinese government has invested heavily in ecosystem restoration and watershed management in recent years. However, the effectiveness of such measures and actions depends on scientific understanding of the complex interplays among ecological, hydrological and socioeconomic factors. This presentation is intended to provide an overview of a major new research initiative supported by the National Natural Science Foundation of China to study the integration of ecological principles, hydrological processes and socioeconomic considerations toward more sustainable exploitation of surface water and groundwater resources in the Hei River Basin in northwest China. The Hei River Basin is an inland watershed located at the center of the arid region in East Asia, stretching from Qilianshan Mountains in the south to the desert in the north bordering China’s Inner Mongolia Autonomous Region and Mongolia. The total area of Hei River Basin is approximately 130,000 km2. The research initiative builds on existing research infrastructure and ecohydrological data and seeks to reveal complex

  10. Integrated hydrologic modeling as a key for sustainable urban water resources planning. (United States)

    Eshtawi, Tamer; Evers, Mariele; Tischbein, Bernhard; Diekkrüger, Bernd


    In this study, a coupling of surface water (SWAT), groundwater (MODFLOW) and solute transport (MT3DMS) models was performed to quantify surface-groundwater and quantity-quality interactions under urban area expansion. The responses of groundwater level, nitrate concentrations (related to human activities) and chloride concentrations (related to seawater intrusion) to urban area expansion and corresponding changes in the urban water budget were examined on a macro-scale level. The potentials of non-conventional water resources scenarios, namely desalination, stormwater harvesting and treated wastewater (TWW) reuse were investigated. In a novel analysis, groundwater improvement and deterioration under each scenario were defined in spatial-temporal approach. The quality deterioration cycle index was estimated as the ratio between the amounts of low and high quality recharge components within the Gaza Strip boundary predicted for year 2030. The improvement index for groundwater level (IIL) and the improvement index for groundwater quality (IIQ) were developed for the scenarios as measures of the effectiveness toward sustainable groundwater planning. Even though the desalination and TWW reuse scenarios reflect a noticeable improvement in the groundwater level, the desalination scenario shows a stronger tendency toward sustainable groundwater quality. The stormwater harvesting scenario shows a slight improvement in both groundwater quality and quantity. This study provides a 'corridor of options', which could facilitate future studies focusing on developing a micro-level assessment of the above scenarios. Copyright © 2016 Elsevier Ltd.

  11. Sustainable Water Systems

    Directory of Open Access Journals (Sweden)

    Miklas Scholz


    Full Text Available Sustainable water systems often comprise complex combinations of traditional and new system components that mimic natural processes. These green systems aim to protect public health and safety, and restore natural and human landscapes. Green infrastructure elements such as most sustainable drainage systems trap storm water but may contaminate groundwater. There is a need to summarize recent trends in sustainable water systems management in a focused document. The aim of this special issue is therefore to disseminate and share scientific findings on novel sustainable water systems addressing recent problems and opportunities. This special issue focuses on the following key topics: climate change adaptation and vulnerability assessment of water resources systems; holistic water management; carbon credits; potable water savings; sustainable water technologies; nutrient management; holistic storm water reuse; water and wastewater infrastructure planning; ecological status of watercourses defined by the Water Framework Directive. The combined knowledge output advances the understanding of sustainable water, wastewater and storm water systems in the developed and developing world. The research highlights the need for integrated decision-support frameworks addressing the impact of climate change on local and national water resources management strategies involving all relevant stakeholders at all levels.

  12. Water Resources and Sustainable Agriculture in 21st Century: Challenges and Opportunities (United States)

    Asrar, G.


    Global agriculture faces some unique challenges and opportunities for the rest of this century. The need for food, feed and fiber will continues to grow as the world population continue to increase in the future. Agricultural ecosystems are also expected to be the source of a significant portion of renewable energy and fuels around the world, without further compromising the integrity of the natural resources base. How can agriculture continue to provide these services to meet the growing needs of world population while sustaining the integrity of agricultural ecosystems and natural resources, the very foundation it depends on? In the last century, scientific discoveries and technological innovations in agriculture resulted in significant increase in food, feed and fiber production globally, while the total amount of water, energy, fertilizers and other input used to achieve this growth remained the same or even decreased significantly in some parts of the world. Scientific and technical advances in understanding global and regional water and energy cycles, water resources management, soil and water conservation practices, weather prediction, plant breeding and biotechnology, and information and communication technologies contributed to this tremendous achievement. The projected increase in global population, urbanization, and changing lifestyles will continue the pressure on both agriculture and other managed and natural ecosystems to provide necessary goods and services for the rest of this century. To meet these challenges, we must obtain the requisite scientific and technical advances in the functioning of Earth's water, energy, carbon and biogeochemical cycles. We also need to apply the knowledge we gain and technologies we develop in assessing Earth's ecosystems' conditions, and their management and stewardship. In agricultural ecosystems, management of soil and water quality and quantity together with development of new varieties of plants based on advances

  13. A hybrid system dynamics and optimization approach for supporting sustainable water resources planning in Zhengzhou City, China (United States)

    Li, Zhi; Li, Chunhui; Wang, Xuan; Peng, Cong; Cai, Yanpeng; Huang, Weichen


    Problems with water resources restrict the sustainable development of a city with water shortages. Based on system dynamics (SD) theory, a model of sustainable utilization of water resources using the STELLA software has been established. This model consists of four subsystems: population system, economic system, water supply system and water demand system. The boundaries of the four subsystems are vague, but they are closely related and interdependent. The model is applied to Zhengzhou City, China, which has a serious water shortage. The difference between the water supply and demand is very prominent in Zhengzhou City. The model was verified with data from 2009 to 2013. The results show that water demand of Zhengzhou City will reach 2.57 billion m3 in 2020. A water resources optimization model is developed based on interval-parameter two-stage stochastic programming. The objective of the model is to allocate water resources to each water sector and make the lowest cost under the minimum water demand. Using the simulation results, decision makers can easily weigh the costs of the system, the water allocation objectives, and the system risk. The hybrid system dynamics method and optimization model is a rational try to support water resources management in many cities, particularly for cities with potential water shortage and it is solidly supported with previous studies and collected data.

  14. Evaluation of groundwater artificial recharge management scenario for sustainable water resources development in Gaza Strip (United States)

    Rusteberg, Bernd; Azizur Rahman, M.; Abusaada, Muath; Rabi, Ayman; Rahman Tamimi, A.; Sauter, Martin


    The water resources in Gaza Strip are currently facing extreme over-exploitation which has led to a sharp decline of the groundwater level in this Mediterranean coastal aquifer overtime. Salinity of the groundwater is very high as a result of subsequent seawater intrusion of the aquifer. The contamination of the Gaza Strip groundwater by seawater has wide-ranging effects on the regional economy as well as agricultural productivity. In order to guarantee the sustainability of regional development, which requires the access to clean water, groundwater artificial recharge (AR) is being considered as a potential solution to this current water resources problem. The objective of the present study is to analyze several strategies for the implementation and management of AR in Gaza Strip and their potential impacts on agriculture, environment, and the socio-economy. Based on the water policy on wastewater reclamation and reuse (Yr. 2005 - 2025), six AR management strategies were developed in close cooperation with the local stakeholder community. These scenarios take into consideration the development of the new North Gaza Wastewater Treatment Plant and were also judged with respect to a base-line scenario, otherwise known as the "Do Nothing Approach." Multi-Criteria Decision Analysis (MCDA) on ranking of the AR management scenarios was used. Twenty-one criteria ranging over a wide spectrum and four categories (Environmental, Public Health, Social, and Economical) were defined to ensure sound evaluation of each of the six AR management scenarios. A detailed geo-database was prepared to analyze all the related spatial, non-spatial, and temporal data. Socio-economic studies, field surveys, mathematical modeling, and GIS analysis were used for the criteria quantification. In the MCDA, Analytical Hierarchy Method (AHP) combined with weighted Linear Combination (WLC) and Composite Programming (CP) was employed. The six AR management strategies were thus compared to the "Do

    Directory of Open Access Journals (Sweden)

    Joel Hernández-Bedolla


    Full Text Available Integrated water resource management (IWRM is facing great challenges due to growing uncertainties caused by climate change (CC, rapid socio-economic and technological changes, and population growth. In the present study, we have developed different indices to assess the availability of water using an IWRM approach. These indices evaluate supply to demands, surface availability, groundwater availability, reservoirs, and environmental flow. Moreover, reliability, resilience, and vulnerability were determined. Sustainability index (SI and sustainability index by groups (SG were determined based on the five indices (all indices vary from 0 to 1. The impacts of climate change affect surface and groundwater availability, as do the agricultural, urban, and industrial requirements on the different supplies. We used the generalized AQUATOOL Decision Support System Shell (DSSS to evaluate the IWRM in the Rio Grande Basin (Morelia, México. Various emission scenarios from representative concentration pathways (RCPs were applied to the basin for the years 2015–2039 and 2075–2099. The results indicate increases in agricultural and urban demand, and decreases in surface runoff, as well as groundwater recharge. The proposed indices are useful for different approaches (decision-makers, water policy, and drought risks, among others. CC significantly affects the different proposed indices and indicates a decrease of the SI, SG1, and SG2 (i.e., less availability. For example, we found that SG2 decreased from 0.812 to 0.195 under the RCP 8.5 2075–2099 scenario, and SG2 equal to 0.252 and 0.326 for the RCP 6.0 2075–2099 and RCP 4.5 2070–2099 scenarios, respectively (values close to 0 indicate worst drought conditions.

  18. A Life-cycle Approach to Improve the Sustainability of Rural Water Systems in Resource-Limited Countries

    Directory of Open Access Journals (Sweden)

    Nicholas Stacey


    Full Text Available A WHO and UNICEF joint report states that in 2008, 884 million people lacked access to potable drinking water. A life-cycle approach to develop potable water systems may improve the sustainability for such systems, however, a review of the literature shows that such an approach has primarily been used for urban systems located in resourced countries. Although urbanization is increasing globally, over 40 percent of the world’s population is currently rural with many considered poor. In this paper, we present a first step towards using life-cycle assessment to develop sustainable rural water systems in resource-limited countries while pointing out the needs. For example, while there are few differences in costs and environmental impacts for many improved rural water system options, a system that uses groundwater with community standpipes is substantially lower in cost that other alternatives with a somewhat lower environmental inventory. However, a LCA approach shows that from institutional as well as community and managerial perspectives, sustainability includes many other factors besides cost and environment that are a function of the interdependent decision process used across the life cycle of a water system by aid organizations, water user committees, and household users. These factors often present the biggest challenge to designing sustainable rural water systems for resource-limited countries.

    extension and the optimal peculiarities for the new channelling, for a sustainable use of underground water resources. The methodology consisted principally of topographic and water level measurements through wells and piezometers. Most of these measurements were made in water wells that already exist, due to the existence of the old khettara, while in the areas where enough density of measurement points is not found, new piezometres have been realised. Moreover, an analysis of rain gauge data and a valuation of the quantity of the underground water taken from the system have been carried out, in order to make a first hydrogeological balance. From the achieved results with the hydrogeological study an extension of the khettara of 230 m with a E-W direction has been made, that allowed to reintercept the alluvial ground water and to create a drainage system able to pick up the underground water in a sustainable way, also during the driest period of the year. Work carried out with a Bambini nel Deserto project, with the financial support of UNDP, the local ONG AHT Hassi Labiad in collaboration with Osservatorio Mediterraneo Onlus.

    Directory of Open Access Journals (Sweden)

    Ashton Maherry


    Full Text Available The Klein Karoo is situated in the Western Cape, South Africa, and is characterised by low rainfall (100–450 mm yr–1. The Klein Karoo is situated in the primary catchment of the Gouritz River. The mean annual runoff (MAR for the three major tributaries of the Gouritz River arising in or feeding the Klein Karoo (Touws, Gamka, Olifants is 540 Mm3 yr–1. Groundwater recharge in the three Klein Karoo catchments is ±257 Mm3 yr–1, but only a portion of this reaches the rivers. The very variable flows result in low 1:50 year yield of 161 Mm3 (30% of MAR. The current demand for water in these catchments is 182 Mm3 yr–1, which exceeds the yield, and demand is projected to increase between 23% and 150% by 2025. Changes in the approach to water management are required, including improving the efficiency of irrigation and land restoration to improve water infiltration and reduce soil erosion. We believe that it is time to change to a water management approach that is designed to anticipate and manage the inherent variability in water resources in the Klein Karoo, thereby placing the region on a path to sustainable development.

  3. Balancing water resources development and environmental sustainability in Africa: a review of recent research findings and applications. (United States)

    McClain, Michael E


    Sustainable development in Africa is dependent on increasing use of the continent's water resources without significantly degrading ecosystem services that are also fundamental to human wellbeing. This is particularly challenging in Africa because of high spatial and temporal variability in the availability of water resources and limited amounts of total water availability across expansive semi-arid portions of the continent. The challenge is compounded by ambitious targets for increased water use and a rush of international funding to finance development activities. Balancing development with environmental sustainability requires (i) understanding the boundary conditions imposed by the continent's climate and hydrology today and into the future, (ii) estimating the magnitude and spatial distribution of water use needed to meet development goals, and (iii) understanding the environmental water requirements of affected ecosystems, their current status and potential consequences of increased water use. This article reviews recent advancements in each of these topics and highlights innovative approaches and tools available to support sustainable development. While much remains to be learned, scientific understanding and technology should not be viewed as impediments to sustainable development on the continent.

  4. A review of methods for monitoring streamflow for sustainable water resource management (United States)

    Dobriyal, Pariva; Badola, Ruchi; Tuboi, Chongpi; Hussain, Syed Ainul


    Monitoring of streamflow may help to determine the optimum levels of its use for sustainable water management in the face of climate change. We reviewed available methods for monitoring streamflow on the basis of six criteria viz. their applicability across different terrains and size of the streams, operational ease, time effectiveness, accuracy, environmental impact that they may cause and cost involve in it. On the basis of the strengths and weaknesses of each of the methods reviewed, we conclude that the timed volume method is apt for hilly terrain having smaller streams due to its operational ease and accuracy of results. Although comparatively expensive, the weir and flume methods are suitable for long term studies of small hill streams, since once the structure is put in place, it yields accurate results. In flat terrain, the float method is best suited for smaller streams for its operational ease and cost effectiveness, whereas, for larger streams, the particle image velocimetry may be used for its accuracy. Our review suggests that the selection of a method for monitoring streamflow may be based on volume of the stream, accuracy of the method, accessibility of the terrain and financial and physical resources available.

  5. Strategies for a sustainable management of water resources in horticulture and floriculture


    Enrico Farina; Antonio Elia


    A more efficient use of water resources in agriculture, especially in horticulture and floriculture, is a concerning issue to choose sounder technical and agronomical practices for managing these resources vis-à-vis: a feasible water economy, the enhancement of natural equilibria and at the same time an increased crop competitiveness. In horticulture, several options are suitable: cultivar choice, timing and type of cropping system, fertilization plan and soil preparation, as well ...

Here we promote dragonflies as an easy-to-learn tool in environmental education…

  9. Sustainability and Water (United States)

    Sharma, Virender A.


    World's population numbered 6.1 billion in 2000 and is currently increasing at a rate of about 77 million per year. By 2025, the estimated total world population will be of the order of 7.9 billion. Water plays a central role in any systematic appraisal of life sustaining requirements. Water also strongly influences economic activity (both production and consumption) and social roles. Fresh water is distributed unevenly, with nearly 500 million people suffering water stress or serious water scarcity. Two-thirds of the world's population may be subjected to moderate to high water stress in 2025. It is estimated that by 2025, the total water use will increase by to 40%. The resources of water supply and recreation may also come under stress due to changes in climate such as water balance for Lake Balaton (Hungary). Conventional urban water systems such as water supply, wastewater, and storm water management are also currently going through stress and require major rethinking. To maintain urban water systems efficiently in the future, a flexibility approach will allow incorporation of new technologies and adaptation to external changes (for example society or climate change). Because water is an essential resource for sustaining health, both the quantity and quality of available water supplies must be improved. The impact of water quality on human health is severe, with millions of deaths each year from water-borne diseases, while water pollution and aquatic ecosystem destruction continue to rise. Additionally, emerging contaminants such as endocrine disruptor chemicals (EDCs), pharmaceuticals, and toxins in the water body are also of a great concern. An innovative ferrate(VI) technology is highly effective in removing these contaminants in water. This technology is green, which addresses problems associated with chlorination and ozonation for treating pollutants present in water and wastewater. Examples are presented to demonstrate the applications of ferrate

  14. A system dynamics simulation model for sustainable water resources management and agricultural development in the Volta River Basin, Ghana. (United States)

    Kotir, Julius H; Smith, Carl; Brown, Greg; Marshall, Nadine; Johnstone, Ron


    In a rapidly changing water resources system, dynamic models based on the notion of systems thinking can serve as useful analytical tools for scientists and policy-makers to study changes in key system variables over time. In this paper, an integrated system dynamics simulation model was developed using a system dynamics modelling approach to examine the feedback processes and interaction between the population, the water resource, and the agricultural production sub-sectors of the Volta River Basin in West Africa. The objective of the model is to provide a learning tool for policy-makers to improve their understanding of the long-term dynamic behaviour of the basin, and as a decision support tool for exploring plausible policy scenarios necessary for sustainable water resource management and agricultural development. Structural and behavioural pattern tests, and statistical test were used to evaluate and validate the performance of the model. The results showed that the simulated outputs agreed well with the observed reality of the system. A sensitivity analysis also indicated that the model is reliable and robust to uncertainties in the major parameters. Results of the business as usual scenario showed that total population, agricultural, domestic, and industrial water demands will continue to increase over the simulated period. Besides business as usual, three additional policy scenarios were simulated to assess their impact on water demands, crop yield, and net-farm income. These were the development of the water infrastructure (scenario 1), cropland expansion (scenario 2) and dry conditions (scenario 3). The results showed that scenario 1 would provide the maximum benefit to people living in the basin. Overall, the model results could help inform planning and investment decisions within the basin to enhance food security, livelihoods development, socio-economic growth, and sustainable management of natural resources.

    Sander, Graham C.; T. Zheng; Heng, P.; Zhong, Y.; Barry, David Andrew


    With the projected increase in world population to 9 billion by 2050, along with per capita income growth, the demand for land and water resources is going to increase significantly. Conversion of land to intensive agriculture has led to dramatic decreases in plant, animal and insect biodiversity, with approximately 40% of the world’s land surface now covered by croplands and pastures. Intensive agricultural practices cause erosion and lead to transport of soil particles and associated sorbed...

  16. Linking knowledge with action in the pursuit of sustainable water-resources management. (United States)

    Jacobs, Katharine; Lebel, Louis; Buizer, James; Addams, Lee; Matson, Pamela; McCullough, Ellen; Garden, Po; Saliba, George; Finan, Timothy


    Managing water for sustainable use and economic development is both a technical and a governance challenge in which knowledge production and sharing play a central role. This article evaluates and compares the role of participatory governance and scientific information in decision-making in four basins in Brazil, Mexico, Thailand, and the United States. Water management institutions in each of the basins have evolved during the last 10-20 years from a relatively centralized water-management structure at the state or national level to a decision structure that involves engaging water users within the basins and the development of participatory processes. This change is consistent with global trends in which states increasingly are expected to gain public acceptance for larger water projects and policy changes. In each case, expanded citizen engagement in identifying options and in decision-making processes has resulted in more complexity but also has expanded the culture of integrated learning. International funding for water infrastructure has been linked to requirements for participatory management processes, but, ironically, this study finds that participatory processes appear to work better in the context of decisions that are short-term and easily adjusted, such as water-allocation decisions, and do not work so well for longer-term, high-stakes decisions regarding infrastructure. A second important observation is that the costs of capacity building to allow meaningful stakeholder engagement in water-management decision processes are not widely recognized. Failure to appreciate the associated costs and complexities may contribute to the lack of successful engagement of citizens in decisions regarding infrastructure.

  18. Water quality status of dugouts from five districts in Northern Ghana: implications for sustainable water resources management in a water stressed tropical savannah environment. (United States)

    Cobbina, Samuel J; Anyidoho, Louis Y; Nyame, Frank; Hodgson, I O A


    This study was primarily aimed at investigating the physicochemical and microbial quality of water in 14 such dugouts from five districts in the northern region of Ghana. Results obtained suggest that except for colour, turbidity, total iron and manganese, many physicochemical parameters were either within or close to the World Health Organisation's acceptable limits for drinking water. Generally, colour ranged from 5 to 750 Hz (mean 175 Hz), turbidity from 0.65 to 568 nephelometric turbidity units (NTU; mean 87.9 NTU), total iron from 0.07 to 7.85 mg/L (mean 1.0 mg/L) and manganese from 0.03 to 1.59 mg/L (mean 0.50 mg/L). Coliform counts in water from all the dugouts in both wet and dry seasons were, however, above the recommended limits for drinking water. Total and faecal coliforms ranged from 125 to 68,000 colony forming units (cfu)/100 mL (mean 10,623 cfu/100 mL) and water, strongly suggests susceptibility and exposure to waterborne diseases of, and consequent health implications on, the many people who continuously patronise these vital water resources throughout the year. In particular, more proactive sustainable water management options, such as introduction to communities of simple but cost-effective purification techniques for water drawn from dugouts for drinking purposes, education and information dissemination to the water users to ensure environmentally hygienic practices around dugouts, may be needed.

  19. Water resources management in the urban agglomeration of the Lake Biwa region, Japan: An ecosystem services-based sustainability assessment. (United States)

    Chen, Xiaochen; Chen, Yuqing; Shimizu, Toshiyuki; Niu, Jia; Nakagami, Ken'ichi; Qian, Xuepeng; Jia, Baoju; Nakajima, Jun; Han, Ji; Li, Jianhua


    An innovative ecosystem services-based sustainability assessment was conducted in the important urban agglomeration of the Lake Biwa region, Japan, covering the time period from 1950 to 2014. A 22-indicator system was established that was based on the major ecosystem services of Lake Biwa and its water courses, i.e., provisioning services regarding aquatic products and water; regulating services regarding floods and water quality; cultural services regarding recreation and tourism, scientific research, and environmental education; and supporting services regarding biodiversity. First, changes in the eight ecosystem services were discussed together with the considerable experience and difficult lessons that can be drawn from the development trajectory. Next, with the indicators rearranged according to sustainability principles, the regional sustainability over the past six-plus decades was assessed. In general, this urban agglomeration has been progressing in terms of its sustainability, although economic and social development was achieved at the cost of environmental degradation in the past, and the current economic downturn is hurting the balanced development and integrated benefits. The results lead directly to recommendations for regional development, especially in terms of economic rejuvenation, from the perspective of improving management of Lake Biwa's water resources. Moreover, the relevant knowledge is educational and inspirational for other places in the world that are facing similar development issues. For example, the effective and even pioneering countermeasures that have been taken against environmental degradation, as well as the participation and collaboration of multiple stakeholders, could be useful as a model. Moreover, the study invites increased understanding of ecosystem vulnerability to anthropogenic devastation and emphasizes the priority of precautionary measures over countermeasures in the context of holistic urban planning and sustainable

  20. Combining Interactive Infrastructure Modeling and Evolutionary Algorithm Optimization for Sustainable Water Resources Design (United States)

    Smith, R.; Kasprzyk, J. R.; Zagona, E. A.


    Population growth and climate change, combined with difficulties in building new infrastructure, motivate portfolio-based solutions to ensuring sufficient water supply. Powerful simulation models with graphical user interfaces (GUI) are often used to evaluate infrastructure portfolios; these GUI based models require manual modification of the system parameters, such as reservoir operation rules, water transfer schemes, or system capacities. Multiobjective evolutionary algorithm (MOEA) based optimization can be employed to balance multiple objectives and automatically suggest designs for infrastructure systems, but MOEA based decision support typically uses a fixed problem formulation (i.e., a single set of objectives, decisions, and constraints). This presentation suggests a dynamic framework for linking GUI-based infrastructure models with MOEA search. The framework begins with an initial formulation which is solved using a MOEA. Then, stakeholders can interact with candidate solutions, viewing their properties in the GUI model. This is followed by changes in the formulation which represent users' evolving understanding of exigent system properties. Our case study is built using RiverWare, an object-oriented, data-centered model that facilitates the representation of a diverse array of water resources systems. Results suggest that assumptions within the initial MOEA search are violated after investigating tradeoffs and reveal how formulations should be modified to better capture stakeholders' preferences.

  1. Sustainability of integrated land and water resources management in the face of climate and land use changes (United States)

    Setegn, Shimelis


    Sustainable development integrates economic development, social development, and environmental protection. Land and Water resources are under severe pressure from increasing populations, fast development, deforestation, intensification of agriculture and the degrading environment in many part of the world. The demand for adequate and safe supplies of water is becoming crucial especially in the overpopulated urban centers of the Caribbean islands. Moreover, population growth coupled with environmental degradation and possible adverse impacts of land use and climate change are major factors limiting freshwater resource availability. The main objective of this study is to develop a hydrological model and analyze the spatiotemporal variability of hydrological processes in the Caribbean islands of Puerto Rico and Jamaica. Physically based eco-hydrological model was developed and calibrated in the Rio Grande Manati and Wag water watershed. Spatial distribution of annual hydrological processes, water balance components for wet and dry years, and annual hydrological water balance of the watershed are discussed. The impact of land use and climate change are addressed in the watersheds. Appropriate nature based adaptation strategies were evaluated. The study will present a good understanding of advantages and disadvantages of nature-based solutions for adapting climate change, hydro-meteorological risks and other extreme hydrological events.

  2. Understanding barotrauma in fish passing hydro structures: a global strategy for sustainable development of water resources

    Freshwater fishes are one of the most imperiled groups of vertebrates and species declines have been linked to a number of anthropogenic influences. This is alarming as the diversity and stability of populations are at risk. In addition, freshwater fish serve as important protein sources, particularly in developing countries. One of the focal activities thought to influence freshwater fish population declines is water resource development, which is anticipated to increase over the next several decades. For fish encountering hydro structures, such as passing through hydroturbines, there may be a rapid decrease in pressure which can lead to injuries commonly referred to as barotraumas. The authors summarize the research to date that has examined the effects of rapid pressure changes on fish and outline the most important factors to consider (i.e., swim bladder morphology, depth of acclimation, migration pattern and life stage) when examining the susceptibility of barotraumas for fish of interest.

  3. Sustainable Water Resource Management and Participatory System Dynamics. Case Study: Developing the Palouse Basin Participatory Model

    Directory of Open Access Journals (Sweden)

    Barbara Cosens


    Full Text Available The complexity of explaining highly scientific information and juggling a plethora of social values is leading agencies and communities such as those in the Palouse Basin to explore the use of participatory modeling processes using system dynamics. Participatory system dynamics as a methodology creates a transparent nexus of science, policy options, social concerns and local knowledge that enhances discussion of issues surrounding the use of natural resources. The process of developing a systems model uses the tenets of scientific theory, hypothesis testing and clear statements of assumptions. A unique aspect of the Palouse basin project is the use of system dynamics to describe ground water dynamics in a sole source confined aquifer system. There are, as of yet, no standards for analyzing participatory modeling projects, therefore, we use case study analysis to describe the process, insights and qualitative measurements of success.

  4. Solute transport characterization in karst aquifers by tracer injection tests for a sustainable water resource management (United States)

    Morales, T.; Angulo, B.; Uriarte, J. A.; Olazar, M.; Arandes, J. M.; Antiguedad, I.


    Protection of water resources is a major challenge today, given that territory occupation and land use are continuously increasing. In the case of karst aquifers, its dynamic complexity requires the use of specific methodologies that allow establishing local and regional flow and transport patterns. This information is particularly necessary when springs and wells harnessed for water supply are concerned. In view of the present state of the art, this work shows a new approach based on the use of a LiCl based tracer injection test through a borehole for transport characterization from a local to a regional scale. Thus a long term tracer injection test was conducted in a particularly sensitive sector of the Egino karst massif (Basque Country, Spain). The initial displacement of tracer in the vicinity of the injection was monitored in a second borehole at a radial distance of 10.24 m. This first information, assessed by a radial divergent model, allows obtaining transport characteristic parameters in this immediate vicinity during injection. At a larger (regional) scale, the tracer reaches a highly transmissive network with mean traveling velocities to the main springs being from 4.3 to 13.7 m/h. The responses obtained, particularly clear in the main spring used for water supply, and the persistence of part of the tracer in the injection zone, pose reconsidering the need for their protection. Thus, although the test allows establishing the 24-h isochrone, which is the ceiling value in present European vulnerability approaches, the results obtained advise widening the zone to protect in order to guarantee water quality in the springs. Overall, this stimulus-response test allows furthering the knowledge on the dynamics of solute transport in karst aquifers and is a particularly useful tool in studies related to source vulnerability and protection in such a complex medium.

  5. Understanding and predicting climate variations in the Middle East for sustainable water resource management and development (United States)

    Samuels, Rana

    data from local stations are developed. These are used to develop scenarios for local rainfall statistics such as average annual amounts, dry spells, wet spells and drought persistence. This suite of models can provide information that is not attainable from existing tools in terms of its spatial and temporal resolution. Specifically, the goal is to project the impact of established global climate change scenarios in this region and, how much of the change might be mitigated by proposed CO2 reduction strategies. A major problem in this enterprise is to find the best way to integrate global climatic information with local rainfall data. From the climatologic perspective the problem is to find the right teleconnections. That is, non local or global measurable phenomena that influence local rainfall in a way that could be characterized and quantified statistically. From the computational perspective the challenge is to model these subtle, nonlinear relationships and to downscale the global effects into local predictions. Climate simulations to the year 2100 under selected climate change scenarios are used. Overall, the suite of models developed and presented can be applied to answer most questions from the different water users and planners. Farmers and the irrigation community can ask "What is the probability of rain over the next week?" Policy makers can ask "How much desalination capacity will I need to meet demand 90% of the time in the climate change scenario over the next 20 years?" Aquifer managers can ask "What is the expected recharge rate of the aquifers over the next decade?" The use of climate driven answers to these questions will help the region better prepare and adapt to future shifts in water resources and availability.

  6. NASA Water Resources Program (United States)

    Toll, David L.


    With increasing population pressure and water usage coupled with climate variability and change, water issues are being reported by numerous groups as the most critical environmental problems facing us in the 21st century. Competitive uses and the prevalence of river basins and aquifers that extend across boundaries engender political tensions between communities, stakeholders and countries. In addition to the numerous water availability issues, water quality related problems are seriously affecting human health and our environment. The potential crises and conflicts especially arise when water is competed among multiple uses. For example, urban areas, environmental and recreational uses, agriculture, and energy production compete for scarce resources, not only in the Western U.S. but throughout much of the U.S. and also in numerous parts of the world. Mitigating these conflicts and meeting water demands and needs requires using existing water resources more efficiently. The NASA Water Resources Program Element works to use NASA products and technology to address these critical water issues. The primary goal of the Water Resources is to facilitate application of NASA Earth science products as a routine use in integrated water resources management for the sustainable use of water. This also includes the extreme events of drought and floods and the adaptation to the impacts from climate change. NASA satellite and Earth system observations of water and related data provide a huge volume of valuable data in both near-real-time and extended back nearly 50 years about the Earth's land surface conditions such as precipitation, snow, soil moisture, water levels, land cover type, vegetation type, and health. NASA Water Resources Program works closely to use NASA and Earth science data with other U.S. government agencies, universities, and non-profit and private sector organizations both domestically and internationally. The NASA Water Resources Program organizes its

    Cianfrani, C. M.


    Teaching Sustainable Water Resources and Low Impact Development: A Project Centered Course for First-Year Undergraduates Christina M. Cianfrani Assistant Professor, School of Natural Science, Hampshire College, 893 West Avenue, Amherst, MA 01002 Sustainable water resources and low impact development principles are taught to first-year undergraduate students using an applied design project sited on campus. All students at Hampshire College are required to take at least one natural science course during their first year as part of their liberal arts education. This requirement is often met with resistance from non-science students. However, ‘sustainability’ has shown to be a popular topic on campus and ‘Sustainable Water Resources’ typically attracts ~25 students (a large class size for Hampshire College). Five second- or third-year students are accepted in the class as advanced students and serve as project leaders. The first-year students often enter the class with only basic high school science background. The class begins with an introduction to global water resources issues to provide a broad perspective. The students then analyze water budgets, both on a watershed basis and a personal daily-use basis. The students form groups of 4 to complete their semester project. Lectures on low impact design principles are combined with group work sessions for the second half of the semester. Students tour the physical site located across the street from campus and begin their project with a site analysis including soils, landcover and topography. They then develop a building plan and identify preventative and mitigative measures for dealing with stormwater. Each group completes TR-55 stormwater calculations for their design (pre- and post-development) to show the state regulations for quantity will be met with their design. Finally, they present their projects to the class and prepare a formal written report. The students have produced a wide variety of creative

  8. Progressive development of water resources in the Middle East for sustainable water supply in a period of climate change. (United States)

    Issar, Arie S; Adar, Eilon


    The history of the Middle East has been influenced by past global climatic changes. Warm periods caused droughts, resulting in desertification, migration and war. Cold periods were humid and brought prosperity and agricultural settlement to the desert fringes. The forecast based on this correlation is that the present global warming will cause the drying up of the Middle East. As in the past, this negative impact should be mitigated by using the groundwater resources stored from past wetter times. This will involve deep drilling, pumping and modern irrigation methods within the framework of a new policy of 'progressive development', which will entail the use of currently undeveloped natural water resources beyond that of present water replenishment. While the use of the one-time groundwater reserves is taking place, a master long-term comprehensive progressive development plan for the Middle East will be prepared. This plan will include the step-by-step development of other water resources such as treated effluents, desalinated brackish groundwater and desalination of seawater.

  10. Towards sustainability in water recycling. (United States)

    Sala, L; Serra, M


    Those like us who believe in and spread the gospel of planned wastewater reclamation and reuse usually emphasize that this is a step towards sustainability in water resource management, but this is something that is very seldom analyzed. This paper discusses, from a critical point of view, issues such as goals in water reuse and influence on water demands, ecological analysis of the cycle of the main pollutants, health aspects and treatment requirements, energy consumption and measurable environmental benefits, in order to provide a set of criteria to assess sustainability in water recycling projects and to decrease the impact of the cultural water cycle on the environment.

  11. Process oriented thinking as a key for integration of ecohydrology, biotechnology and engineering for sustainable water resources management and ecosystems (United States)

    Zalewski, M.


    The recent high rate of environmental degradation due to unsustainable use of water and other natural resources and mismanagement, is, in many cases, the result of a dominant sectoral approach, limited communication between different users and agencies, and lack of knowledge transfer between different disciplines, and especially lack of dialogue between environmental scientists and engineers. There is no doubt that the genuine improvement of human well-being has to be based on understanding the complexity of interactions between abiotic, biotic and socio-economic systems. The major drivers of biogeosphere evolution and function have been the cycles of water and nutrients in a complex array of differing climates and catchment geomorphologies. In the face of global climate change and unequally distributed human populations, the recent sectoral mechanistic approach in natural resources management has to be replaced by an evolutionary systems approach based on well-integrated problem-solving and policy-oriented environmental science. Thus the principles of ecohydrology should be the basis for further integration of ecology, hydrology, engineering, biotechnology and other environmental sciences. Examples from UNESCO IHP VII show how the integration of these will not only increase the efficiency of measures to harmonize ecosystem potentials with societal needs, but also significantly reduce the costs of sustainable environmental management.

  12. Water Resources Sustainability in Northwest Mexico: Analysis of Regional Infrastructure Plans under Historical and Climate Change Scenarios (United States)

    Che, D.; Robles-Morua, A.; Mayer, A. S.; Vivoni, E. R.


    The arid state of Sonora, Mexico, has embarked on a large water infrastructure project to provide additional water supply and improved sanitation to the growing capital of Hermosillo. The main component of the Sonora SI project involves an interbasin transfer from rural to urban water users that has generated conflicts over water among different social sectors. Through interactions with regional stakeholders from agricultural and water management agencies, we ascertained the need for a long-term assessment of the water resources of one of the system components, the Sonora River Basin (SRB). A semi-distributed, daily watershed model that includes current and proposed reservoir infrastructure was applied to the SRB. This simulation framework allowed us to explore alternative scenarios of water supply from the SRB to Hermosillo under historical (1980-2010) and future (2031-2040) periods that include the impact of climate change. We compared three precipitation forcing scenarios for the historical period: (1) a network of ground observations from Mexican water agencies; (2) gridded fields from the North America Land Data Assimilation System (NLDAS) at 12 km resolution; and (3) gridded fields from the Weather Research and Forecasting (WRF) model at 10 km resolution. These were compared to daily historical observations at two stream gauging stations and two reservoirs to generate confidence in the simulation tools. We then tested the impact of climate change through the use of the A2 emissions scenario and HadCM3 boundary forcing on the WRF simulations of a future period. Our analysis is focused on the combined impact of existing and proposed reservoir infrastructure at two new sites on the water supply management in the SRB under historical and future climate conditions. We also explore the impact of climate variability and change on the bimodal precipitation pattern from winter frontal storms and the summertime North American monsoon and its consequences on water

  13. Pollution and sanitation problems as setbacks to sustainable water resources management in Freetown. (United States)

    Kallon, Senesie B


    The civil conflict in Sierra Leone (1991-2001) caused a dramatic increase in the population of Freetown. This population increase overstretched housing facilities, leading to the creation of camps and many squatter settlements with poor sanitation practices. Overcrowding has become a serious concern in light of the acute water shortage that struck Freetown in May and June 2006. Some of the numerous small water bodies that could have been used to augment the public water supply were contaminated by the disposal of solid and industrial waste and poor sewage management. Improper disposal practices have a direct impact on public health. This paper recommends addressing the policy gap, establishing clear threshold criteria for all water bodies and wastewater discharge, and integrating the above issues in the ongoing review process of draft water sanitation policy. Public education of the negative consequences of poor waste management practices on water quality and public health can also positively affect general sanitation practices

  14. Water - an inexhaustible resource? (United States)

    Le Divenah, C.; Esperou, E.


    We have chosen to present the topic "Water", by illustrating problems that will give better opportunities for interdisciplinary work between Natural Science (Physics, Chemistry, Biology and Geology) teachers at first, but also English teachers and maybe others. Water is considered in general, in all its shapes and states. The question is not only about drinking water, but we would like to demonstrate that water can both be a fragile and short-lived resource in some ways, and an unlimited energy resource in others. Water exists on Earth in three states. It participates in a large number of chemical and physical processes (dissolution, dilution, biogeochemical cycles, repartition of heat in the oceans and the atmosphere, etc.), helping to maintain the homeostasis of the entire planet. It is linked to living beings, for which water is the major compound. The living beings essentially organized themselves into or around water, and this fact is also valid for human kind (energy, drinking, trade…). Water can also be a destroying agent for living beings (tsunamis, mud flows, collapse of electrical dams, pollution...) and for the solid earth (erosion, dissolution, fusion). I) Water, an essential resource for the human kind After having highlighted the disparities and geopolitical problems, the pupils will study the chemistry of water with its components and their origins (isotopes, water trip). Then the ways to make it drinkable will be presented (filtration, decantation, iceberg carrying…) II) From the origin of water... We could manage an activity where different groups put several hypotheses to the test, with the goal to understand the origin(s?) of water on Earth. Example: Isotopic signature of water showing its extraterrestrial origin.. Once done, we'll try to determine the origin of drinking water, as a fossil resource. Another use of isotopes will allow them to evaluate the drinking water age, to realize how precious it can be. III) Water as a sustainable energy

  15. Sustainable polymers from renewable resources. (United States)

    Zhu, Yunqing; Romain, Charles; Williams, Charlotte K


    Renewable resources are used increasingly in the production of polymers. In particular, monomers such as carbon dioxide, terpenes, vegetable oils and carbohydrates can be used as feedstocks for the manufacture of a variety of sustainable materials and products, including elastomers, plastics, hydrogels, flexible electronics, resins, engineering polymers and composites. Efficient catalysis is required to produce monomers, to facilitate selective polymerizations and to enable recycling or upcycling of waste materials. There are opportunities to use such sustainable polymers in both high-value areas and in basic applications such as packaging. Life-cycle assessment can be used to quantify the environmental benefits of sustainable polymers.

  17. Water Quality and Sustainable Environmental Health (United States)

    Setegn, S. G.


    Lack of adequate safe water, the pollution of the aquatic environment and the mismanagement of resources are major causes of ill-health and mortality, particularly in the developing countries. In order to accommodate more growth, sustainable fresh water resource management will need to be included in future development plans. One of the major environmental issues of concern to policy-makers is the increased vulnerability of ground water quality. The main challenge for the sustainability of water resources is the control of water pollution. To understand the sustainability of the water resources, one needs to understand the impact of future land use and climate changes on the natural resources. Providing safe water and basic sanitation to meet the Millennium Development Goals will require substantial economic resources, sustainable technological solutions and courageous political will. A balanced approach to water resources exploitation for development, on the one hand, and controls for the protection of health, on the other, is required if the benefits of both are to be realized without avoidable detrimental effects manifesting themselves. Meeting the millennium development goals for water and sanitation in the next decade will require substantial economic resources, sustainable technological solutions and courageous political will. In addition to providing "improved" water and "basic" sanitation services, we must ensure that these services provide: safe drinking water, adequate quantities of water for health, hygiene, agriculture and development and sustainable sanitation approaches to protect health and the environment.

    Zhengning Pu


    Full Text Available China’s water pollution is severe and has a negative impact on its residents. Establishing an emissions trading mechanism will be helpful for reducing the pollution. However, the government in China controls the emission rights market. The “GDP Only” preference blocks equitable rules to address the externalities. To modify this distortion, we develop a multi-objective primary distribution model that optimizes economic efficiency, environmental contribution, and fairness. In addition, the geographical location of a company and the industry differential are two key factors that would affect the local government’s decision. According to the simulation results using data from Tai Lake in China, this model can effectively help to meet the political expectation that large-scale manufacturers with poor technology can take the initiative to reduce emissions through emission-rights distribution.

    Full Text Available Water is a primary element in the human diet and a necessary resource for the agriculture. In addition, industrial practices need a growing amount of water. Since human population is continuously growing at a quasi-exponential rate, water demand, for domestic, agricultural and industrial uses, is increasing too. However, considering that the water resources on the Earth are finite, even disregarding the potential threats due to the climate change, this situation appears as one of the biggest challenges of the current era. Actually, one-third of the world’s population is water-stressed, of which 12% severely: in these nations, a large portion of the population lives below the minimum threshold judged permissible for a decent life. In practice, almost every nation deals with problems related to water sustainability. In some countries, the water supply is ensured only thanks to the extraction of fossil water, which is a limited resource that will not last indefinitely. The impact on water quality has also dramatically increased. The scarcity of water resources is expected to spread to wider areas in the near future, mostly in developing countries, if the actual trends of development and population growth do not change. The rapid urbanizing rate will also create additional stress. Climate change can in turn alter both water supply and demand: increasing temperatures will reflect in increased evaporation and decreased stream flows. Rising seas could contaminate groundwater resources, and increasingly variable precipitation will likely mean more frequent high-intensity droughts and floods and less available rainfall in arid and semiarid regions. The effects of these changes will increase the natural variability of the climate, exacerbating the extreme climatic phenomena (drought and flood events, increasing the difficulty of managing water resources, especially in the most vulnerable regions, and affecting water availability even in regions that are

  3. Ideas towards sustainable water security (United States)

    Dalin, Carole


    With growing global demands and a changing climate, ensuring water security - the access to sufficient, quality water resources for health and livelihoods and an acceptable level of water related risk - is increasingly challenging. While a billion people still lack access to water, over-exploitation of this resource increases in many developed and developing parts of the world. While some solutions to water stress have been known for a long time, financial, cultural and political barriers often prevent their implementations. This talk will highlight three crucial areas that need to be addressed to progress towards sustainable water security. The first point is on scale, the second on the agricultural sector and irrigation, and the third on food trade and policy.

  5. Hydrological modeling as a tool for sustainable water resources management: a case study of the Awash River Basin

    Energy Technology Data Exchange (ETDEWEB)

    Tessema, Selome M.


    The growing pressure on the world's fresh water resources is enforced by population growth that leads to conflicts between demands for different purposes. A main concern on water use is the conflict between the environment and other purposes like hydropower, irrigation for agriculture and domestic and industry water supply, where total flows are diverted without releasing water for ecological conservation. As a consequence, some of the common problems related to water faced by many countries are shortage, quality deterioration and flood impacts. Hence, utilization of integrated water resources management in a single system, which is built up by river basin, is an optimum way to handle the question of water. However, in many areas, when planning for balancing water demands major gaps exist on baseline knowledge of water resources. In order to bridge these gaps, hydro-logical models are among the available tools used to acquire adequate understanding of the characteristics of the river basin. Apart from forecasting and predicting the quantity and quality of water for decision makers, some models could also help in predicting the impacts of natural and anthropogenic changes on water resources and also in quantifying the spatial and temporal availability of the resources. However, main challenges lie in choosing and utilizing these models for a specific basin and managerial plan. In this study, an analysis of the different types of models and application of a selected model to characterize the Awash River basin, located in Ethiopia, is presented. The results from the modeling procedure and the performance of the model are discussed. The different possible sources of uncertainties in the modeling process are also discussed. The results indicate dissimilar predictions in using different methods; hence proper care must be taken in selecting and employing available methods for a specific watershed prior to presenting the results to decision makers

  8. Water Footprints and Sustainable Water Allocation

    Directory of Open Access Journals (Sweden)

    Arjen Y. Hoekstra


    Full Text Available Water Footprint Assessment (WFA is a quickly growing research field. This Special Issue contains a selection of papers advancing the field or showing innovative applications. The first seven papers are geographic WFA studies, from an urban to a continental scale; the next five papers have a global scope; the final five papers focus on water sustainability from the business point of view. The collection of papers shows that the historical picture of a town relying on its hinterland for its supply of water and food is no longer true: the water footprint of urban consumers is global. It has become clear that wise water governance is no longer the exclusive domain of government, even though water is and will remain a public resource with government in a primary role. With most water being used for producing our food and other consumer goods, and with product supply chains becoming increasingly complex and global, there is a growing awareness that consumers, companies and investors also have a key role. The interest in sustainable water use grows quickly, in both civil society and business communities, but the poor state of transparency of companies regarding their direct and indirect water use implies that there is still a long way to go before we can expect that companies effectively contribute to making water footprints more sustainable at a relevant scale.

  11. Use of participatory modeling workshops in a water-stressed basin of northern Mexico to assess sustainable water resources management and conduct community outreach (United States)

    Vivoni, E. R.; Mayer, A. S.; Halvorsen, K. E.; Robles-Morua, A.; Kossak, D.


    A series of iterative participatory modeling workshops were held in Sonora, México with the goal of developing water resources management strategies in a water-stressed basin subject to hydro-climatic variability and change. A model of the water resources system, consisting of watershed hydrology, water resources infrastructure, and groundwater models, was developed deliberatively in the workshops, along with scenarios of future climate and development. Participants used the final version of the water resources systems model to select from supply-side and demand-side water resources management strategies. The performance of the strategies was based on the reliability of meeting current and future demands at a daily time scale over a year's period. Pre- and post-workshop surveys were developed and administered. The survey questions focused on evaluation of participants' modeling capacity and the utility and accuracy of the models. The selected water resources strategies and the associated, expected reliability varied widely among participants. Most participants could be clustered into three groups with roughly equal numbers of participants that varied in terms of reliance on expanding infrastructure vs. demand modification; expectations of reliability; and perceptions of social, environmental, and economic impacts. The wide range of strategies chosen and associated reliabilities indicate that there is a substantial degree of uncertainty in how future water resources decisions could be made in the region. The pre- and post-survey results indicate that participants believed their modeling abilities increased and beliefs in the utility of models increased as a result of the workshops

  12. Sustaining Waters: From Hydrology to Drinking Water (United States)

    Toch, S.


    Around the world, disastrous effects of floods and droughts are painful evidence of our continuing struggle between human resource demands and the sustainability of our hydrologic systems. Too much or too little rainfall is often deemed the culprit in these water crises, focussing on water "lacks and needs" instead of exploring the mechanisms of the hydrologic functions and processes that sustain us. Applicable to regions around the world, this unified approach is about our human and environmental qualities with user friendly concepts and how-to guides backed up by real life experiences. From the poorest parts of Africa to Urban France to the wealthest state in the USA, examples from surface to groundwater to marine environments demonstrate how the links between vulerable natural areas, and the basins that they support are integral to the availability, adequacy and accessibility of our drinking water. Watershed management can be an effective means for crisis intervention and pollution control. This project is geared as a reference for groups, individuals and agencies concerned with watershed management, a supplement for interdisciplinary high school through university curriculam, for professional development in technical and field assistance, and for community awareness in the trade-offs and consequences of resource decisions that affect hydrologic systems. This community-based project demonstrates how our human resource demands can be managed within ecological constraints. An inter-disciplinary process is developed that specifically assesses risk to human health from resource use practices, and explores the similarities and interations between our human needs and those of the ecosystems in which we all must live together. Disastrous conditions worldwide have triggered reactions in crisis relief rather than crisis prevention. Through a unified management approach to the preservation of water quality, the flows of water that connect all water users can serve as a

  13. Toward A Science of Sustainable Water Management (United States)

    Brown, C.


    Societal need for improved water management and concerns for the long-term sustainability of water resources systems are prominent around the world. The continued susceptibility of society to the harmful effects of hydrologic variability, pervasive concerns related to climate change and the emergent awareness of devastating effects of current practice on aquatic ecosystems all illustrate our limited understanding of how water ought to be managed in a dynamic world. The related challenges of resolving the competition for freshwater among competing uses (so called "nexus" issues) and adapting water resources systems to climate change are prominent examples of the of sustainable water management challenges. In addition, largely untested concepts such as "integrated water resources management" have surfaced as Sustainable Development Goals. In this presentation, we argue that for research to improve water management, and for practice to inspire better research, a new focus is required, one that bridges disciplinary barriers between the water resources research focus on infrastructure planning and management, and the role of human actors, and geophysical sciences community focus on physical processes in the absence of dynamical human response. Examples drawn from climate change adaptation for water resource systems and groundwater management policy provide evidence of initial progress towards a science of sustainable water management that links improved physical understanding of the hydrological cycle with the socioeconomic and ecological understanding of water and societal interactions.

    Mohtar, Rabi; Daher, Bassel; Mekki, Insaf; Chaibi, Thameur; Zitouna Chebbi, Rim; Salaymeh, Ahmed Al


    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

    Barlow, P. M.; Filali-Meknassi, Y.; Sanford, W. E.; Winston, R. B.; Kuniansky, E.; Dawson, C.


    UNESCO's HOPE Initiative—the Hydro Free and (or) Open-source Platform of Experts—was launched in June 2013 as part of UNESCO's International Hydrological Programme. The Initiative arose in response to a recognized need to make free and (or) open-source water-resources software more widely accessible to Africa's water sector. A kit of software is being developed to provide African water authorities, teachers, university lecturers, and researchers with a set of programs that can be enhanced and (or) applied to the development of efficient and sustainable management strategies for Africa's water resources. The Initiative brings together experts from the many fields of water resources to identify software that might be included in the kit, to oversee an objective process for selecting software for the kit, and to engage in training and other modes of capacity building to enhance dissemination of the software. To date, teams of experts from the fields of wastewater treatment, groundwater hydrology, surface-water hydrology, and data management have been formed to identify relevant software from their respective fields. An initial version of the HOPE Software Kit was released in late August 2014 and consists of the STOAT model for wastewater treatment developed by the Water Research Center (United Kingdom) and the MODFLOW-2005 model for groundwater-flow simulation developed by the U.S. Geological Survey. The Kit is available on the UNESCO HOPE website ( in the theory and use of MODFLOW-2005 is planned in southern Africa in conjunction with UNESCO's study of the Kalahari-Karoo/Stampriet Transboundary Aquifer, which extends over an area that includes parts of Botswana, Namibia, and South Africa, and in support of the European Commission's Horizon 2020 FREEWAT project (FREE and open source software tools for WATer resource management; see the UNESCO HOPE website).

  17. Is current irrigation sustainable in the United States? An integrated assessment of climate change impact on water resources and irrigated crop yields. (United States)

    Blanc, Elodie; Caron, Justin; Fant, Charles; Monier, Erwan


    While climate change impacts on crop yields has been extensively studied, estimating the impact of water shortages on irrigated crop yields is challenging because the water resources management system is complex. To investigate this issue, we integrate a crop yield reduction module and a water resources model into the MIT Integrated Global System Modeling framework, an integrated assessment model linking a global economic model to an Earth system model. We assess the effects of climate and socioeconomic changes on water availability for irrigation in the U.S. as well as subsequent impacts on crop yields by 2050, while accounting for climate change projection uncertainty. We find that climate and socioeconomic changes will increase water shortages and strongly reduce irrigated yields for specific crops (i.e., cotton and forage), or in specific regions (i.e., the Southwest) where irrigation is not sustainable. Crop modeling studies that do not represent changes in irrigation availability can thus be misleading. Yet, since the most water-stressed basins represent a relatively small share of U.S. irrigated areas, the overall reduction in U.S. crop yields is small. The response of crop yields to climate change and water stress also suggests that some level of adaptation will be feasible, like relocating croplands to regions with sustainable irrigation or switching to less irrigation intensive crops. Finally, additional simulations show that greenhouse gas (GHG) mitigation can alleviate the effect of water stress on irrigated crop yields, enough to offset the reduced CO 2 fertilization effect compared to an unconstrained GHG emission scenario.

  20. Trading off natural resources and rural livelihoods. A framework for sustainability assessment of small-scale food production in water-limited regions (United States)

    Recanati, Francesca; Castelletti, Andrea; Dotelli, Giovanni; Melià, Paco


    Enhancing local production is key to promoting food security, especially in rural households of low-income countries, but may conflict with limited natural resources and ecosystems preservation. We propose a framework integrating the water-food nexus and a sustainable livelihoods perspective to assess small-scale food production in water-poor regions. We demonstrate it by assessing alternative production scenarios in the Gaza Strip at different spatial scales. At the scale of a single farm, there is a clear conflict among objectives: while cash crops ensure good incomes but contribute scarcely to domestic protein supply, crops performing well from the nutritional and environmental viewpoint are among the worst from the economic one. At the regional scale, domestic production might cover an important fraction of nutritional needs while contributing to household income, but water scarcity impairs the satisfaction of food demand by domestic production alone. Pursuing food security under multiple constraints thus requires a holistic perspective: we discuss how a multidimensional approach can promote the engagement of different stakeholders and allow the exploration of trade-offs between food security, sustainable exploitation of natural resources and economic viability.

  1. Citizen science in hydrology and water resources: opportunities for knowledge generation, ecosystem service management, and sustainable development

    Directory of Open Access Journals (Sweden)

    Wouter eBuytaert


    Full Text Available The participation of the general public in the research design, data collection and interpretation process together with scientists is often referred to as citizen science. While citizen science itself has existed since the start of scientific practice, developments in sensing technology, data processing and visualisation, and communication of ideas and results, are creating a wide range of new opportunities for public participation in scientific research. This paper reviews the state of citizen science in a hydrological context and explores the potential of citizen science to complement more traditional ways of scientific data collection and knowledge generation for hydrological sciences and water resources management. Although hydrological data collection often involves advanced technology, the advent of robust, cheap and low-maintenance sensing equipment provides unprecedented opportunities for data collection in a citizen science context. These data have a significant potential to create new hydrological knowledge, especially in relation to the characterisation of process heterogeneity, remote regions, and human impacts on the water cycle. However, the nature and quality of data collected in citizen science experiments is potentially very different from those of traditional monitoring networks. This poses challenges in terms of their processing, interpretation, and use, especially with regard to assimilation of traditional knowledge, the quantification of uncertainties, and their role in decision support. It also requires care in designing citizen science projects such that the generated data complement optimally other available knowledge. Lastly, we reflect on the challenges and opportunities in the integration of hydrologically-oriented citizen science in water resources management, the role of scientific knowledge in the decision-making process, and the potential contestation to established community institutions posed by co-generation of

    Khadse, G K; Labhasetwar, P K; Wate, S R


    Water is precious natural resource for sustaining life and environment. Effective and sustainable management of water resources is vital for ensuring sustainable development. In view of the vital importance of water for human and animal life, for maintaining ecological balance and for economic and developmental activities of all kinds, and considering its increasing scarcity, the planning and management of water resource and its optimal, economical and equitable use has become a matter of the utmost urgency. Management of water resources in India is of paramount importance to sustain one billion plus population. Water management is a composite area with linkage to various sectors of Indian economy including the agricultural, industrial, domestic and household, power, environment, fisheries and transportation sector. The water resources management practices should be based on increasing the water supply and managing the water demand under the stressed water availability conditions. For maintaining the quality of freshwater, water quality management strategies are required to be evolved and implemented. Decision support systems are required to be developed for planning and management of the water resources project. There is interplay of various factors that govern access and utilization of water resources and in light of the increasing demand for water it becomes important to look for holistic and people-centered approaches for water management. Clearly, drinking water is too fundamental and serious an issue to be left to one institution alone. It needs the combined initiative and action of all, if at all we are serious in socioeconomic development. Safe drinking water can be assured, provided we set our mind to address it. The present article deals with the review of various options for sustainable water resource management in India.

This program is in line with all projects the Algerian Government is implementing to improve its water sector performance. The water strategy focuses on desalination for the coastal cities, medium-sized dams to irrigate the inland mountains and high plateau, and ambitious water transfer projects interconnecting Algeria\\'s 65 dams to bring water to water scarce parts of the country. Waste water treatment and water reclamation technologies are also highly sought after. The main objective of the country\\'s water policy consists on providing sufficient potable water for the population supply. This objective is undertaken by increasing the water resources and availability. © 2012 Desalination Publications. All rights reserved.

  6. The Texas Water Observatory: Utilizing Advanced Observing System Design for Understanding Water Resources Sustainability Across Climatic and Geologic Gradients of Texas (United States)

    Mohanty, B.; Moore, G. W.; Miller, G. R.; Quiring, S. M.; Everett, M. E.; Morgan, C.


    The Texas Water Observatory (TWO) is a new distributed network of field observatories for better understanding of the hydrologic flow in the critical zone (encompassing groundwater, soil water, surface water, and atmospheric water) at various space and time scales. Core sites in the network will begin in Brazos River corridor and expand from there westward. Using many advanced observational platforms and real-time / near-real time sensors, this observatory will monitor high frequency data of water stores and fluxes, critical for understanding and modeling the in the state of Texas and Southern USA. Once implemented, TWO will be positioned to support high-impact water science that is highly relevant to societal needs and serve as a regional resource for better understanding and/or managing agriculture, water resources, ecosystems, biodiversity, disasters, health, energy, and weather/climate. TWO infrastructure will span land uses (cultivation agriculture, range/pasture, forest), landforms (low-relief erosional uplands to depositional lowlands), and across climatic and geologic gradients of Texas to investigate the sensitivity and resilience of fertile soils and the ecosystems they support. Besides developing a network of field water observatory infrastructure/capacity for accounting water flow and storage, TWO will facilitate developing a new generation interdisciplinary water professionals (from various TAMU Colleges) with better understanding and skills for attending to future water challenges of the region. This holistic growth will have great impact on TAMU research enterprise related to water resources, leading to higher federal and state level competitiveness for funding and establishing a center of excellence in the region

  7. Resource linkages and sustainable development (United States)

    Anouti, Yahya

    Historically, fossil fuel consumers in most developing hydrocarbon-rich countries have enjoyed retail prices at a discount from international benchmarks. Governments of these countries consider the subsidy transfer to be a means for sharing the wealth from their resource endowment. These subsidies create negative economic, environmental, and social distortions, which can only increase over time with a fast growing, young, and rich population. The pressure to phase out these subsidies has been mounting over the last years. At the same time, policy makers in resource-rich developing countries are keen to obtain the greatest benefits for their economies from the extraction of their exhaustible resources. To this end, they are deploying local content policies with the aim of increasing the economic linkages from extracting their resources. Against this background, this dissertation's three essays evaluate (1) the global impact of rationalizing transport fuel prices, (2) how resource-rich countries can achieve the objectives behind fuel subsidies more efficiently through direct cash transfers, and (3) the economic tradeoffs from deploying local content policies and the presence of an optimal path. We begin by reviewing the literature and building the case for rationalizing transport fuel prices to reflect their direct costs (production), indirect costs (road maintenance) and negative externalities (climate change, local pollutants, traffic accidents and congestion). To do so, we increase the scope of the economic literature by presenting an algorithm to evaluate the rationalized prices in different countries. Then, we apply this algorithm to quantify the rationalized prices across 123 countries in a partial equilibrium setting. Finally, we present the first comprehensive measure of the impact of rationalizing fuel prices on the global demand for gasoline and diesel, environmental emissions, government revenues, and consumers' welfare.

  8. Food security and sustainable resource management (United States)

    McLaughlin, Dennis; Kinzelbach, Wolfgang


    The projected growth in global food demand until mid-century will challenge our ability to continue recent increases in crop yield and will have a significant impact on natural resources. The water and land requirements of current agriculture are significantly less than global reserves but local shortages are common and have serious impacts on food security. Recent increases in global trade have mitigated some of the effects of spatial and temporal variability. However, trade has a limited impact on low-income populations who remain dependent on subsistence agriculture and local resources. Potential adverse environmental impacts of increased agricultural production include unsustainable depletion of water and soil resources, major changes in the global nitrogen and phosphorous cycles, human health problems related to excessive nutrient and pesticide use, and loss of habitats that contribute to agricultural productivity. Some typical case studies from China illustrate the connections between the need for increased food production and environmental stress. Sustainable options for decreasing food demand and for increasing production include reduction of food losses on both the producer and consumer ends, elimination of unsustainable practices such as prolonged groundwater overdraft, closing of yield gaps with controlled expansions of fertilizer application, increases in crop yield and pest resistance through advances in biotechnology, and moderate expansion of rain fed and irrigated cropland. Calculations based on reasonable assumptions suggest that such measures could meet the food needs of an increasing global population while protecting the environment.

  9. Modern water resources engineering

  11. Lunar Water Resource Demonstration (United States)

    Muscatello, Anthony C.


    In cooperation with the Canadian Space Agency, the Northern Centre for Advanced Technology, Inc., the Carnegie-Mellon University, JPL, and NEPTEC, NASA has undertaken the In-Situ Resource Utilization (ISRU) project called RESOLVE. This project is a ground demonstration of a system that would be sent to explore permanently shadowed polar lunar craters, drill into the regolith, determine what volatiles are present, and quantify them in addition to recovering oxygen by hydrogen reduction. The Lunar Prospector has determined these craters contain enhanced hydrogen concentrations averaging about 0.1%. If the hydrogen is in the form of water, the water concentration would be around 1%, which would translate into billions of tons of water on the Moon, a tremendous resource. The Lunar Water Resource Demonstration (LWRD) is a part of RESOLVE designed to capture lunar water and hydrogen and quantify them as a backup to gas chromatography analysis. This presentation will briefly review the design of LWRD and some of the results of testing the subsystem. RESOLVE is to be integrated with the Scarab rover from CMIJ and the whole system demonstrated on Mauna Kea on Hawaii in November 2008. The implications of lunar water for Mars exploration are two-fold: 1) RESOLVE and LWRD could be used in a similar fashion on Mars to locate and quantify water resources, and 2) electrolysis of lunar water could provide large amounts of liquid oxygen in LEO, leading to lower costs for travel to Mars, in addition to being very useful at lunar outposts.

    Constanze Leemhuis


    Full Text Available Land Use Land Cover Change (LULCC has a significant impact on water resources and ecosystems in sub-Saharan Africa (SSA. On the basis of three research projects we aim to describe and discuss the potential, uncertainties, synergies and science-policy interfaces of satellite-based integrated research for the Kilombero catchment, comprising one of the major agricultural utilized floodplains in Tanzania. LULCC was quantified at the floodplain and catchment scale analyzing Landsat 5 and Sentinel 2 satellite imagery applying different adapted classification methodologies. LULC maps at the catchment scale serve as spatial input for the distributed, process-based ecohydrological model SWAT (Soil Water Assessment Tool simulating the changes in the spatial and temporal water balance in runoff components caused by LULCC. The results reveal that over the past 26 years LULCC has significantly altered the floodplain and already shows an impact on the ecosystem by degrading the existing wildlife corridors. On the catchment scale the anomalies of the water balance are still marginal, but with the expected structural changes of the catchment there is an urgent need to increase the public awareness and knowledge of decision makers regarding the effect of the relationship between LULCC, water resources and environmental degradation.

    Full Text Available Water is undoubtedly the most precious resource of the planet and the accessibility to water resources marked the history of mankind since the dawn of times. Water has been indeed very central to archaeology and anthropology, that studied the ways in which water was provisioned, tanked, distributed, worshipped, exploited for agricultural irrigation or to power machines like water-mills, used for leisure, hygiene and healing, or abused to confer power on particular groups ,and how it played a central role in political and economic strategies. More than any other factor, waterways marked cultural and economic developments in history. This paper outlines examples of water resources management throughout the ages, in Cyprus and the Hellenic Civilization on different aspects of the use and management of water, investigates technical issues and gives suggestions, thus promoting a new approach to archaeological heritage and sustainable tourism.

  1. Interdisciplinary approach on evaluation and sustainable usage of the water resources in the semi-arid Northwest Mexico to counter the imbalance of water: Case study Valle de Guadalupe, Baja California (United States)

    Kretzschmar, T.; Hernandez, R.; Valenzuela, C.; Cabello, A.


    In the Baja California peninsula are several watersheds present, of which the hydrogeological conditions are of great importance to communities in the area. The Valle de Guadalupe watershed, for instance has a wine industry of national importance. Irrigation of crops is carried out exclusively with water from the aquifer, which consists of Quaternary sediments filling this depression of Post-Miocene age. Apart from the use of the aquifer by the wine industry, the water utility of Ensenada operates 10 drinking water wells with a total capacity of 320 L/s or 42% of supply in the valley. In the arid northern Mexico mountain front recharge is an important recharge source to the aquifers. Other important recharge sources are related to direct infiltration of the precipitation, recharge from runoff into streams (mountain block recharge) and the provision by active faults. The knowledge of the aquifer is crucial to maintain sustainable management of water resources in the Valle de Guadalupe. This intense use of water resources is reflected in a degradation of the aquifer water quality and reduced water table. The integrated approach for a sustainable evaluation and usage of the aquifer includes besides the hydrogeological evaluation, the determination of the water stress on the vineyards as well as the usage of treated waste water as alternative resource as well the evaluation of the effects of climatic variations and measurement and modeling of the vegetation, the main interface between atmosphere and soil, affecting the hydrology in the process of interception, infiltration, runoff and evapotranspiration. With these detailed ongoing studies we expect to identify and counter imbalance of water in the study area. This requires 1) modeling and hydrogeological studies for the determination of the present and future imbalance 2) estimation of the impacts of industrial activities on water resources 3) characterization of alternative water sources, 4) optimization of the water

  4. Water Resources Compound Systems: A Macro Approach to Analysing Water Resource Issues under Changing Situations

    Directory of Open Access Journals (Sweden)

    Wei Wang


    Full Text Available Water resource crises are an increasing threat to human survival and development. To reveal the nature of water resource issues under changing situations, the water resources system needs to be studied from a macro and systematic perspective. This report develops a water resources system into a water resources compound system that is constantly evolving under the combined action of the development, resistant, and coordination mechanisms. Additionally, the water quotient is defined as a quantitative representation of the sustainable development state of the water resources compound system. Four cities in China, Beijing, Fuzhou, Urumqi, and Lhasa, were selected as the study areas. The differences in the three types of mechanisms and the water quotient of the water resources compound system of each city in 2013 were compared. The results indicate that the different subsystems that comprise the compound system of a given area have different development mechanisms and resistant mechanisms. There are clear differences in the mechanisms and the water quotients for the water resources compound systems of different regions. Pertinent measures should be taken into account during integrated water resource management to improve the sustainable development status of regional water resources compound systems.

    With more than 6 million inhabitants, Abidjan district faces tremendous difficulties in water supply. The aquifer of the Continental Terminal which is actually the only drinking water source of the city shows a decline of resources and water demand is increasing due to the population growth. Moreover significant evidences of chemical and biological pollution of the groundwater are observed The Aghien lagoon, the largest freshwater pool located near Abidjan, has been identified by the State of Côte d'Ivoire as a potential resource for the production of drinking water.. The main objective of this project is to assess the quantitative and qualitative capacity of the Aghien lagoon to complement the water supply of Abidjan city in the near future. The main components of the project are: • to assess the water budget of the lagoon and its tributaries, • to characterize the spatial and temporal variability of contaminant levels and fluxes from the tributaries toward the lagoon, • to assess the sustainability of the water resources (quantity and quality) of the lagoon according to land use changes in the catchments . The project started in January 2015. The first year was devoted to the set-up of hydro-meteorological gauges within the lagoon watershed. Three major tributaries of the lagoon are considered, the Mé (4000 km2), the Djibi (78 km2) and Bete (206 km2) rivers. Since the start of the project, bi-monthly hydrochemical sampling surveys have been carried out along the tributaries and in the lagoon. The data available from the surveys concern the physico-chemical parameters, trace elements, all the forms of nitrogen and phosphorus, organic carbon, suspended solids. The Djibi and Bete watersheds are partly urbanized while the Mé basin is mainly rural. Baseflow has been identified as the major contribution to streamflow at the annual scale. The Mé flows into a channel downstream to the Aghien lagoon but during the floods, water from the Mé River can flow up the

  15. Water Resources Assessment and Management in Drylands

    Directory of Open Access Journals (Sweden)

    Magaly Koch


    Full Text Available Drylands regions of the world face difficult issues in maintaining water resources to meet current demands which will intensify in the future with population increases, infrastructure development, increased agricultural water demands, and climate change impacts on the hydrologic system. New water resources evaluation and management methods will be needed to assure that water resources in drylands are optimally managed in a sustainable manner. Development of water management and conservation methods is a multi-disciplinary endeavor. Scientists and engineers must collaborate and cooperate with water managers, planners, and politicians to successfully adopt new strategies to manage water not only for humans, but to maintain all aspects of the environment. This particularly applies to drylands regions where resources are already limited and conflicts over water are occurring. Every aspect of the hydrologic cycle needs to be assessed to be able to quantify the available water resources, to monitor natural and anthropogenic changes, and to develop flexible policies and management strategies that can change as conditions dictate. Optimal, sustainable water management is achieved by cooperation and not conflict, thereby necessitating the need for high quality scientific research and input into the process.

  20. Sustainable use of phosphorus: a finite resource. (United States)

    Scholz, Roland W; Ulrich, Andrea E; Eilittä, Marjatta; Roy, Amit


    Phosphorus is an essential element of life and of the modern agricultural system. Today, science, policy, agro-industry and other stakeholder groups are increasingly concerned about the sustainable use of this resource, given the dissipative nature of phosphorus and difficulties in assessing, evaluating, and coping with phosphorus pollution in aquatic and terrestrial systems. We argue that predictions about a forthcoming peak, followed by a quick reduction (i.e., physical phosphate rock scarcity) are unreasoned and stress that access to phosphorus (economic scarcity) is already, and may increasingly become critical, in particular for smallholders farmers in different parts of the world. The paper elaborates on the design, development, goals and cutting-edge contributions of a global transdisciplinary process (i.e. mutual learning between science and society including multiple stakeholders) on the understanding of potential contributions and risks related to the current mode of using phosphorus on multiple scales (Global TraPs). While taking a global and comprehensive view on the whole phosphorus-supply chain, Global TraPs organizes and integrates multiple transdisciplinary case studies to better answer questions which inform sustainable future phosphorus use. Its major goals are to contribute to four issues central to sustainable resource management: i) long-term management of biogeochemical cycles, in particular the challenge of closing the phosphorus cycle, ii) achieving food security, iii) avoiding environmental pollution and iv) sustainability learning on a global level by transdisciplinary processes.

A component of the Water Resources Division of the US Geological Survey, the Center maintains a searchable computerized bibliographic data base, and publishers a monthly journal of abstracts. Through its services, the Center is able to provide reliable scientific and technical information about the most recent water resources developments, as well as long-term trends and changes. WRSIC was established in 1966 by the Secretary of the Interior to further the objectives of the Water Resources Research Act of 1964--legislation that encouraged research in water resources and the prevention of needless duplication of research efforts. It was determined the WRSIC should be the national center for information on water resources, covering research reports, scientific journals, and other water resources literature of the world. WRSIC would evaluate all water resources literature, catalog selected articles, and make the information available in publications or by computer access. In this way WRSIC would increase the availability and awareness of water related scientific and technical information. (Lantz-PTT)

  6. Sustainable agricultural water management across climates (United States)

    DeVincentis, A.


    Fresh water scarcity is a global problem with local solutions. Agriculture is one of many human systems threatened by water deficits, and faces unique supply, demand, quality, and management challenges as the global climate changes and population grows. Sustainable agricultural water management is paramount to protecting global economies and ecosystems, but requires different approaches based on environmental conditions, social structures, and resource availability. This research compares water used by conservation agriculture in temperate and tropical agroecosystems through data collected from operations growing strawberries, grapes, tomatoes, and pistachios in California and corn and soybeans in Colombia. The highly manipulated hydrologic regime in California has depleted water resources and incited various adaptive management strategies, varying based on crop type and location throughout the state. Operations have to use less water more efficiently, and sometimes that means fallowing land in select groundwater basins. At the opposite end of the spectrum, the largely untouched landscape in the eastern plains of Colombia are rapidly being converted into commercial agricultural operations, with a unique opportunity to manage and plan for agricultural development with sustainability in mind. Although influenced by entirely different climates and economies, there are some similarities in agricultural water management strategies that could be applicable worldwide. Cover crops are a successful management strategy for both agricultural regimes, and moving forward it appears that farmers who work in coordination with their neighbors to plan for optimal production will be most successful in both locations. This research points to the required coordination of agricultural extension services as a critical component to sustainable water use, successful economies, and protected environments.

In Latin America the general concept of IWRM has proved to be hard to implement. Case studies recommend to develop the approach from lower to upper scale and oriented at the end-user. As IWRM is an interdisciplinary approach and used for very different objectives, the main emphasis is given to IWRM approaches for sustainable irrigation and their environmental aspects. The review shows that in Latin America the environmental impact is mostly analysed at the field level, the impact on the whole basin is less considered. Many publications present the development of models, advisory services and tools for decision support systems at a high technical level. Some papers present studies of environmental aspects of sustainable irrigation, especially for salt affected areas. Multi-criteria decision making models are developed for irrigation planning and irrigation scenarios are used to show the impact of different irrigation management decision. In general integrated approaches in Latin America are scarce.El objetivo de esta publicación es revisar el estado del arte de los diferentes enfoques que se han usado para lograr un manejo integrado de los recursos hídricos (MIRH asociados a una agricultura de riego sustentable a nivel de cuenca en condiciones áridas y semiáridas, con énfasis en Latinoamérica, pero incluyen casos de estudio de otras regiones similares del mundo.

  10. Virtual water trade and time scales for loss of water sustainability: a comparative regional analysis. (United States)

    Goswami, Prashant; Nishad, Shiv Narayan


    Assessment and policy design for sustainability in primary resources like arable land and water need to adopt long-term perspective; even small but persistent effects like net export of water may influence sustainability through irreversible losses. With growing consumption, this virtual water trade has become an important element in the water sustainability of a nation. We estimate and contrast the virtual (embedded) water trades of two populous nations, India and China, to present certain quantitative measures and time scales. Estimates show that export of embedded water alone can lead to loss of water sustainability. With the current rate of net export of water (embedded) in the end products, India is poised to lose its entire available water in less than 1000 years; much shorter time scales are implied in terms of water for production. The two cases contrast and exemplify sustainable and non-sustainable virtual water trade in long term perspective.

  15. Resource management as a key factor for sustainable urban planning. (United States)

    Agudelo-Vera, Claudia M; Mels, Adriaan R; Keesman, Karel J; Rijnaarts, Huub H M


    Due to fast urbanization and increasing living standards, the environmental sustainability of our global society becomes more and more questionable. In this historical review we investigate the role of resources management (RM) and urban planning (UP) and propose ways for integration in sustainable development (SD). RM follows the principle of circular causation, and we reflect on to what extent RM has been an element for urban planning. Since the existence of the first settlements, a close relationship between RM, urbanization and technological development has been present. RM followed the demand for urban resources like water, energy, and food. In history, RM has been fostered by innovation and technology developments and has driven population growth and urbanization. Recent massive resource demand, especially in relation to energy and material flows, has altered natural ecosystems and has resulted in environmental degradation. UP has developed separately in response to different questions. UP followed the demand for improved living conditions, often associated to safety, good manufacturing and trading conditions and appropriate sanitation and waste management. In history UP has been a developing research area, especially since the industrial era and the related strong urbanization at the end of the 18th century. UP responded to new emerging problems in urban areas and became increasingly complex. Nowadays, UP has to address many objectives that are often conflicting, including, the urban sustainability. Our current urban un-sustainability is rooted in massive resource consumption and waste production beyond natural limits, and the absence of flows from waste to resources. Therefore, sustainable urban development requires integration of RM into UP. We propose new ways to this integration. Copyright © 2011 Elsevier Ltd. All rights reserved.

  19. Sustainability analysis of groundwater resources in a coastal aquifer, Alabama (United States)

    Liu, Jie; Rich, Kendall; Zheng, Chunmiao


    Fort Morgan Peninsula is an attached portion of a dynamic barrier complex in the northern Gulf of Mexico and is a large tourist area that brings in a significant amount of revenue for Alabama. Many of the hotels and tourist attractions depend on the groundwater as their water supply. The over-withdrawal of groundwater and saltwater intrustion will have a negative impact on the ecology, tourism and economy if groundwater resources are not properly monitored and managed. In this study a calibrated groundwater flow model was used to analyze the sustainability of groundwater resources at Fort Morgan Peninsula. Detailed flow budgets were prepared to check the various components of inflow and outflow under different water use and climatic conditions. The results indicated the locations where groundwater was over-pumped and subjected to saltwater intrusion, or will be subjected to saltwater intrusion under a range of projected water use and climatic conditions.

  3. Resource reliability, accessibility and governance: pillars for managing water resources to achieve water security in Nepal (United States)

    Biggs, E. M.; Duncan, J.; Atkinson, P.; Dash, J.


    As one of the world's most water-abundant countries, Nepal has plenty of water yet resources are both spatially and temporally unevenly distributed. With a population heavily engaged in subsistence farming, whereby livelihoods are entirely dependent on rain-fed agriculture, changes in freshwater resources can substantially impact upon survival. The two main sources of water in Nepal come from monsoon precipitation and glacial runoff. The former is essential for sustaining livelihoods where communities have little or no access to perennial water resources. Much of Nepal's population live in the southern Mid-Hills and Terai regions where dependency on the monsoon system is high and climate-environment interactions are intricate. Any fluctuations in precipitation can severely affect essential potable resources and food security. As the population continues to expand in Nepal, and pressures build on access to adequate and clean water resources, there is a need for institutions to cooperate and increase the effectiveness of water management policies. This research presents a framework detailing three fundamental pillars for managing water resources to achieve sustainable water security in Nepal. These are (i) resource reliability; (ii) adequate accessibility; and (iii) effective governance. Evidence is presented which indicates that water resources are adequate in Nepal to sustain the population. In addition, aspects of climate change are having less impact than previously perceived e.g. results from trend analysis of precipitation time-series indicate a decrease in monsoon extremes and interannual variation over the last half-century. However, accessibility to clean water resources and the potential for water storage is limiting the use of these resources. This issue is particularly prevalent given the heterogeneity in spatial and temporal distributions of water. Water governance is also ineffective due to government instability and a lack of continuity in policy

  4. Sustainable Water Use System of Artesian Water in Alluvial Fan (United States)

    Kishi, K.; Tsujimura, M.; Tase, N.


    The traditional water use system, developed with the intelligence of the local residents, usually takes advantage of local natural resources and is considered as a sustainable system, because of its energy saving(only forces of nature). For this reason, such kind of water use system is also recommended in some strategic policies for the purpose of a symbiosis between nature and human society. Therefore, it is important to clarify the relationship between human activities and water use systems. This study aims to clarify the mechanism of traditional water use processes in alluvial fan, and in addition, to investigate the important factors which help forming a sustainable water use system from the aspects of natural conditions and human activities. The study area, an alluvial fan region named Adogawa, is located in Shiga Prefecture, Japan and is in the west of Biwa Lake which is the largest lake in Japan. In this alluvial region where the land use is mainly occupied by settlements and paddy fields, a groundwater flowing well system is called "kabata" according to local tradition. During field survey, we took samples of groundwater, river water and lake water as well as measured the potential head of groundwater. The results showed that the upper boundary of flowing water was approximately 88m amsl, which is basically the same as the results reported by Kishi and Kanno (1966). In study area, a rapid increase of water pumping for domestic water use and melting snow during last 50 years, even if the irrigation area has decreased about 30% since 1970, and this fact may cause a decrease in recharge rate to groundwater. However, the groundwater level didn't decline based on the observed results, which is probably contributed by some water conservancy projects on Biwa Lake which maintained the water level of the lake. All the water samples are characterized by Ca-HCO3 type and similar stable isotopic value of δD and δ18O. Groundwater level in irrigation season is higher

  5. Following the Water Cycle to Sustainability (United States)

    Lutz, T. M.


    For scientists, modeling the connections among the parts of complex, dynamic systems is crucial. Doing so lets us understand emergent phenomena such as ecosystem behavior and climate patterns that could not otherwise be predicted. Emergent phenomena can typically only be understood or appreciated when we stand "outside" the system. When scientists take such an outsiders view of earth's systems they can propose many ways that human activities modify the climate system (e.g., increasing or reducing GHG emissions). But what should we do to achieve a sustainable future? Sustainability is an emergent property that arises at the level of the planetary management system, of which the scientific establishment is just a part. We are "insiders" and it is impossible to completely envision the conditions for sustainability or to plan for it. The crises in our atmosphere, biosphere, oceans, and in the natural and energy resource sectors are based in science and do call for urgent changes in science education. But education that focuses solely on science to meet the challenges of sustainability may be as likely to harm humanity's long-term prospects as to improve them. I present activities and teaching strategies that I use in general education classes at West Chester University, a comprehensive institution of roughly 14,000 undergraduates. The overarching concept is to extend "modeling the connections" to the sustainability level and to train students to think outside the system. To make the ideas more accessible, I have the students become sensors at their particular point in the web of connections that constitute the planetary management system. I ask them to evaluate their connection in three domains proposed by John Ehrenfeld (Sustainability by Design, Yale University Press, 2008): sense of place in the natural world; sense of responsibility for our actions, and sense of what it is to be a human being. I have them analyze their sense of connection with reference to a

  6. Water, Society and the future of water resources research (Invited) (United States)

    Brown, C. M.


    The subject of water and society is broad, but at heart is the study of water as a resource, essential to human activities, a vital input to food and energy production, the sustaining medium for ecosystems and yet also a destructive hazard. Society demands, withdraws, competes, uses and wastes the resource in dynamic counterpart. The science of water management emerges from this interface, a field at the nexus of engineering and geoscience, with substantial influence from economics and other social sciences. Within this purview are some of the most pressing environmental questions of our time, such as adaptation to climate change, direct and indirect connections between water and energy policy, the continuing dependence of agriculture on depletion of the world's aquifers, the conservation or preservation of ecosystems within increasingly human-influenced river systems, and food security and poverty reduction for the earth's poorest inhabitants. This presentation will present and support the hypothesis that water resources research is a scientific enterprise separate from, yet closely interrelated to, hydrologic science. We will explore the scientific basis of water resources research, review pressing research questions and opportunities, and propose an action plan for the advancement of the science of water management. Finally, the presentation will propose a Chapman Conference on Water and Society: The Future of Water Resources Research in the spring of 2015.

  10. Water Resource Variability and Climate Change

    Directory of Open Access Journals (Sweden)

    Yingkui Li


    Full Text Available A significant challenge posed by changing climates is how water cycling and surficial and subsurface water availability will be affected at global and regional scales. Such alterations are critical as they often lead to increased vulnerability in ecosystems and human society. Understanding specifically how climate change affects water resource variability in different locations is of critical importance to sustainable development in different parts of the world. The papers included in this special issue focus on three broad perspectives associated with water resource variability and climate change. Six papers employ remote sensing, meteorological station-based observational data, and tree-ring records to empirically determine how water resources have been changing over historical time periods. Eight of the contributions focus on modeling approaches to determine how known processes are likely to manifest themselves as climate shifts over time. Two others focus on human perceptions and adaptation strategies in the midst of unstable or unsettled water availability. The findings and methods presented in this collection of papers provide important contributions to the increased study and awareness of climate change on water resources.

  13. Dynamical resource nexus assessments: from accounting to sustainability approaches (United States)

    Salmoral, Gloria; Yan, Xiaoyu


    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 Sustainable water management (SWM requires allocating between competing water sector demands, and balancing the financial and social resources required to support necessary water systems. The objective of this review is to assess SWM in three sectors: urban, agricultural, and natural systems. This review explores the following questions: (1 How is SWM defined and evaluated? (2 What are the challenges associated with sustainable development in each sector? (3 What are the areas of greatest potential improvement in urban and agricultural water management systems? And (4 What role does country development status have in SWM practices? The methods for evaluating water management practices range from relatively simple indicator methods to integration of multiple models, depending on the complexity of the problem and resources of the investigators. The two key findings and recommendations for meeting SWM objectives are: (1 all forms of water must be considered usable, and reusable, water resources; and (2 increasing agricultural crop water production represents the largest opportunity for reducing total water consumption, and will be required to meet global food security needs. The level of regional development should not dictate sustainability objectives, however local infrastructure conditions and financial capabilities should inform the details of water system design and evaluation.

  20. Sustainable fishing of inland waters

    Directory of Open Access Journals (Sweden)

    Jeppe Kolding


    Full Text Available Sustainability in fisheries has over the past decades evolved from a single species maximization concept to covering ecosystem and biodiversity considerations. This expansion of the notion, together with increased evidence that the targeted removal of selected components of the fish community may have adverse ecological consequences, poses a serious dilemma to the conventional fisheries management approach of protecting juveniles and targeting adults. Recently, the idea of balanced harvest, i.e., harvesting all components in the ecosystem in proportion to their productivity, has been promoted as a unifying solution in accordance with the ecosystem approach to fisheries, but this will require a fundamental change to management. In this paper, we review the objectives, theoretical background, and practicalities of securing high yielding fisheries in inland waters, with empirical examples from tropical freshwater fisheries which satisfy the extended objectives of minimal impact on community and ecosystem structure. We propose a framework of ecological indicators to assess these objectives.  Normal 0 false false false EN-GB ZH-CN HE

  1. Towards Sustainable Water Management in a Country that Faces Extreme Water Scarcity and Dependency: Jordan (United States)

    Schyns, J.; Hamaideh, A.; Hoekstra, A. Y.; Mekonnen, M. M.; Schyns, M.


    Jordan faces a great variety of water-related challenges: domestic water resources are scarce and polluted; the sharing of transboundary waters has led to tensions and conflicts; and Jordan is extremely dependent of foreign water resources through trade. Therefore, sustainable water management in Jordan is a challenging task, which has not yet been accomplished. The objective of this study was to analyse Jordan's domestic water scarcity and pollution and the country's external water dependency, and subsequently review sustainable solutions that reduce the risk of extreme water scarcity and dependency. We have estimated the green, blue and grey water footprint of five different sectors in Jordan: crop production, grazing, animal water supply, industrial production and domestic water supply. Next, we assessed the blue water scarcity ratio for the sum of surface- and groundwater and for groundwater separately, and calculated the water pollution level. Finally, we reviewed the sustainability of proposed solutions to Jordan's domestic water problems and external water dependency in literature, while involving the results and conclusions from our analysis. We have quantified that: even while taking into account the return flows, blue water scarcity in Jordan is severe; groundwater consumption is nearly double the sustainable yield; water pollution aggravates blue water scarcity; and Jordan's external virtual water dependency is 86%. Our review yields ten essential ingredients that a sustainable water management strategy for Jordan, that reduces the risk of extreme water scarcity and dependency, should involve. With respect to these, Jordan's current water policy requires a strong redirection towards water demand management. Especially, more attention should be paid to reducing water demand by changing the consumption patterns of Jordan consumers. Moreover, exploitation of fossil groundwater should soon be halted and planned desalination projects require careful

METHODS: Eleven indicators (covering aspects of water and sewage were selected based on the parameters of Brazil's National Water and Sanitation Information System (Sistema Nacional de Informação sobre Saneamento for the years 2000 and 2001. A score and a weight were assigned to each indicator. Based on that, the urban water sustainability index (UWSI was calculated, using the formula UWSI = product (Ii pi, where Ii is the score

  7. Hydrological Monitoring and Environmental Modeling to Assess the Quality and Sustainability of the Water Resources in an Uranium Mine Area, Caetité - Brazil (United States)

    Franklin, M. R.; van Slobbe, E.; Fernandes, N. F.; Palma, J.; van Dalen, D.; Santos, A. C.; Melo, V.; Reis, R. G.; Carmo, R.; Fernandes, H. M.


    Uranium mining and processing constitute the front-end of the nuclear fuel-cycle and respond for most of its radiological impacts. For many years it has been accepted that the key driving force associated with these radiological impacts was related with radon exhalation from mill tailings. However, evidences coming from other mining sites showed that impacts in superficial and ground waters could also play a significant role. In Brazil, the newest uranium production unit presents a unique opportunity to integrate all the above concepts in a logical framework that will lead to sound and environmental balanced operations. The production center (Caetité plant) consists of open pit mine and sulfuric acid Heap Leach operations and is located at a semi-arid region in northeastern Brazil. Because groundwater is the sole perennial source of water for human consumption and industrial use, this resource has to be managed wisely and efficiently. Therefore, this paper intends to summarize the components of an ongoing project of groundwater management in uranium mining areas. The results will guide the adequate management of groundwater use and provide the basis for the appropriate impact assessment of the potential releases of pollutants. The methodology starts with the mathematical simulation of the long-term behavior of the hydrogeological system based on an experimental basin approach. The occurrence and pattern of groundwater flow in the Caetité experimental basin (CEB) are mainly conditioned by the degree of faulting/fracturing of rocks (predominantly gneisses and granites). Two faulting systems are observed in the area, the principal one, parallel to the foliation (with NW direction) and the secondary one with NE direction. The main water reservoirs in the CEB are related to the intrusion of a diabase dike, which increased the density of fractures in the rocks. This dike serves as natural barrier to the water flow and constrains the potential contamination of

  8. Adapting Landscape Mosaics of medIteranean Rainfed Agrosystems for a sustainable management of crop production, water and soil resources: the ALMIRA project. (United States)

    Jacob, Frédéric; Mekki, Insaf; Chikhaoui, Mohamed


    In the context of mitigating the pressures induced by global change combined with demography and market pressures, there is increasing societal demand and scientific need to understand the functioning of Mediterranean Rainfed Agrosystems (MRAs) for their potential to provide various environmental and economic services of importance such as food production, preservation of employment and local knowhow, downstream water delivery or mitigation of rural exodus. Efficient MRAs management strategies that allow for compromises between economic development and natural resources preservation are needed. Such strategies require innovative system based research, integration across approaches and scales. One of the major challenges is to make all contributions from different disciplines converging towards a reproducible transdisciplinary approach. The objective of this communication is to present the ALMIRA project, a Tunisian - Moroccan - French project which lasts four years (2014 - 2017). The communication details the societal context, the scientific positioning and the related work hypothesis, the study areas, the project structure, the expected outcomes and the partnership which capitalizes on long term collaborations. ALMIRA aims to explore the modulation of landscape mosaics within MRAs to optimize landscape services. To explore this new lever, ALMIRA proposes to design, implement and test a new Integrated Assessment Modelling approach that explicitly i) includes innovations and action means into prospective scenarii for landscape evolutions, and ii) addresses landscape mosaics and processes of interest from the agricultural field to the resource governance catchment. This requires tackling methodological challenges in relation to i) the design of spatially explicit landscape evolution scenarii, ii) the coupling of biophysical processes related to agricultural catchment hydrology, iii) the digital mapping of landscape properties and iv) the economic assessment of the

  9. Brand Awareness towards Sustaining Earth's Resources (United States)

    Sharma, Seema


    School Children are the torchbearers of information, development and awareness in the country. They are the custodians of the future, thus it is important to educate them on this sensitive issue for a secured future for them. They are not rigid in their thoughts and are open to ideas and willing to listen, which gives us an opportunity to sensitize them about the growing issues that will shape their future So my projects with students every year revolves around an impactful contribution in reaching out and building awareness about preserving the environment and incorporating the practices of reuse, reduce and recycle in our daily lives. Under this project I conduct various workshops on recycling waste, debates on the environmental challenges with regular focus on inculcating cleaner habits amongst children ensuring an attitude change which will help create a socially responsible society. The community is enlightened on the importance of being responsible towards own household waste and conservation of the planet by conducting workshops across various residential societies in Pune. The idea is to encourage the young students and teachers to practice the 4Rs - Refuse, Reuse, Reduce and Recycle - in our daily lives. Through workshops, film screening, simulation exercises, competitions and students exchange programs the children are sensitized about waste management and importance of recycling to make them aware of the need to 'Protect What's Good' - which is the environment. And my project provides students a strong platform to voice their concerns about the need to practice sustainable lifestyles. The workshops are ruled by hands-on activities which give students a clear understanding. The activities include- film screening, competitions and debates, smart mobs in malls and public areas, cycle rallies, street plays, paper bag selling, cleanliness drives, collection drives for recyclables and most recently I have started with a new project which is known as social

    André Cavalcante da Silva Batalhão


    Full Text Available The Sustainability Indicators are parameters that characterize past events, evidence situational portraits of the present and assist in projecting future scenarios in relation to sustainability. These instruments allow periodic checks of the process of sustainable development at various scales. The Barometer of Sustainability fits this proposal, because, treating men and nature equally, it assesses the degree of sustainability and has been used from local to national scope. Within this perspective, the basic aim of this research was to analyze the quality dimension of water resources in the development of this instrument, taking as an example the city of Ribeirão Preto, SP, Brazil. The adopted methodology had as its main foundation the Seven Stages Cycle for implementing the Barometer of Sustainability. The Barometer of Sustainability as an assessment tool has proved to be useful in contributing to the understanding of natural phenomena, being relevant to the analysis of water resources at the local level. This tool is a component part of an environmental management process and cannot be considered alone. The Barometer of Sustainability showed that Ribeirão Preto is at a reasonable level in relation to the water resources which were analyzed and considered in the research. The index of the theme Water, originated from the assessment tool, showed the highest value among the other topics discussed in the Ecological Subsystem for the city, being in health and environmental compliance.

  12. Smart Markets for Water Resources (United States)

    Raffensperger, John


    Commercial water users often want to trade water, but their trades can hurt other users and the environment. So government has to check every transaction. This checking process is slow and expensive. That's why "free market" water trading doesn't work, especially with trading between a single buyer and a single seller. This talk will describe a water trading mechanism designed to solve these problems. The trading mechanism is called a "smart market". A smart market allows simultaneous many-to-many trades. It can reduce the transaction costs of water trading, while improving environmental outcomes. The smart market depends on a combination of recent technologies: hydrology simulation, computer power, and the Internet. Our smart market design uses standard hydrological models, user bids from a web page, and computer optimization to maximize the economic value of water while meeting all environmental constraints. Before the smart market can be implemented, however, users and the water agency must meet six critical prerequisites. These prerequisites may be viewed as simply good water management that should be done anyway. I will describe these prerequisites, and I will briefly discuss common arguments against water markets. This talk will be an abstract of a forthcoming book, "Smart Markets for Water Resources: A Manual for Implementation," by John F. Raffensperger and Mark W. Milke, from Springer Publishing.

    Champollion, N; Benveniste, J; Chen, J


    This book is a collection of overview articles showing how space-based observations, combined with hydrological modeling, have considerably improved our knowledge of the continental water cycle and its sensitivity to climate change. Two main issues are highlighted: (1) the use in combination of space observations for monitoring water storage changes in river basins worldwide, and (2) the use of space data in hydrological modeling either through data assimilation or as external constraints. The water resources aspect is also addressed, as well as the impacts of direct anthropogenic forcing on land hydrology (e.g. ground water depletion, dam building on rivers, crop irrigation, changes in land use and agricultural practices, etc.). Remote sensing observations offer important new information on this important topic as well, which is highly useful for achieving water management objectives. Over the past 15 years, remote sensing techniques have increasingly demonstrated their capability to monitor components of th...

  15. Water from (waste)water--the dependable water resource. (United States)

    Asano, Takashi


    Water reclamation and reuse provides a unique and viable opportunity to augment traditional water supplies. As a multi-disciplined and important element of water resources development and management, water reuse can help to close the loop between water supply and wastewater disposal. Effective water reuse requires integration of water and reclaimed water supply functions. The successful development of this dependable water resource depends upon close examination and synthesis of elements from infrastructure and facilities planning, wastewater treatment plant siting, treatment process reliability, economic and financial analyses, and water utility management. In this paper, fundamental concepts of water reuse are discussed including definitions, historical developments, the role of water recycling in the hydrologic cycle, categories of water reuse, water quality criteria and regulatory requirements, and technological innovations for the safe use of reclaimed water. The paper emphasizes the integration of this alternative water supply into water resources planning, and the emergence of modern water reclamation and reuse practices from wastewater to reclaimed water to repurified water.

  16. Managed Sustainable Development Classification Of Resources And Goods amp Services Calculating Sustainable Growth Rate And The Sustainable Development Index

    Directory of Open Access Journals (Sweden)

    Shubham Saxena


    Full Text Available Macro-level manmade problems can often be best solved by understanding and manipulating the economics behind it. The world today is facing genuine problems of scarcity of resources and environmental amp ecological issues in view of intergenerational equity. The paper proposes a new approach of identification and classification of i Resources and ii Goods and services in the context of sustainable development. Every economy has ambitious economic growth aspirations which are often found conflicting with the commitments on natural resource conservation and climate change obligations. The proposed methodology is a reconciliation of the aspired economic growth of a region and the conservation of the resources and nature. The paper employs contribution of different types of goods and services in the gross domestic product GDP of a region to analyze sustainability of development. The important parameters that the paper establishes are Sustainability Ratio R Sustainable Growth Rate SG and the Sustainable Development Index SI. These parameters can be used to compare the sustainable development level of different regions. Ensuring natural resource and environmental sustainability will eventually ensure economic sustainability. The paper considers resource depletion concerns as well as the environmental pollutants biological risks carbon footprint warhead proliferation et cetera thereby ensuring all round sustainability from survival to economic end. The sustainability analysis is done for long periods such as 50 years 100 years et cetera. The index shows how sustainable the development of an economy is and how sustainability it is growing. The presently much revered GDP growth numbers are directionless it does not tell the type of growth an economy essentially has. The direction should be sustainability which the paper stresses upon. An illustration of sustainability analysis of India is also done. Such indices can help identifying sustainably developing

  20. Sustainability of Ancient Water Supply Facilities in Jerusalem

    Directory of Open Access Journals (Sweden)

    Jamal M. Barghouth


    Full Text Available This paper presents an overview on the sustainability of ancient water supply systems in Jerusalem from the Chalcolithic period (4500–3200 B.C. until the present time. Archaeological evidences and landscape settings were applied utilizing all available and accessible literature relevant to ancient water resources management in Jerusalem. Irrigated agriculture was practiced for many centuries in this region, hence sustainable water supply facilities were erected, including well developed aqueducts, water harvesting pools and irrigation channels for water storage and landscaping purposes. To cope with seismic events, soil subsidence and water leakage, ancient water engineers and architects applied innovative construction methods for the erection of water pools, channels and aqueduct systems. Ancient water supply systems in Jerusalem are valuable treasures of past civilizations and crucial urban environmental facilities and their protection is consistent with sustainable development principles. Effective environmental assessment as a decision-making process for sustainable development can be applied to preserve threatened ancient water facilities from major development proposals and urban infrastructure projects in Jerusalem.

    Urban areas such as megacities (those with populations greater than 10 million) are hotspots of global water use and thus face intense water management challenges. Urban areas are influenced by local interactions between human and natural systems and interact with distant systems through flows of water, food, energy, people, information, and capital. However, analyses of water sustainability and the management of water flows in urban areas are often fragmented. There is a strong need to apply...

  6. Game Theory in water resources management (United States)

    Katsanevaki, Styliani Maria; Varouchakis, Emmanouil; Karatzas, George


    Rural water management is a basic requirement for the development of the primary sector and involves the exploitation of surface/ground-water resources. Rational management requires the study of parameters that determine their exploitation mainly environmental, economic and social. These parameters reflect the influence of irrigation on the aquifer behaviour and on the level-streamflow of nearby rivers as well as on the profit from the farming activity for the farmers' welfare. The question of rural water management belongs to the socio-political problems, since the factors involved are closely related to user behaviour and state position. By applying Game Theory one seeks to simulate the behaviour of the system 'surface/ground-water resources to water-users' with a model based on a well-known game, "The Prisoner's Dilemma" for economic development of the farmers without overexploitation of the water resources. This is a game of two players that have been extensively studied in Game Theory, economy and politics because it can describe real-world cases. The present proposal aims to investigate the rural water management issue that is referred to two competitive small partnerships organised to manage their agricultural production and to achieve a better profit. For the farmers' activities water is required and ground-water is generally preferable because consists a more stable recourse than river-water which in most of the cases in Greece are of intermittent flow. If the two farmer groups cooperate and exploit the agreed water quantities they will gain equal profits and benefit from the sustainable availability of the water recourses (p). If both groups overexploitate the resource to maximize profit, then in the medium-term they will incur a loss (g), due to the water resources reduction and the increase of the pumping costs. If one overexploit the resource while the other use the necessary required, then the first will gain great benefit (P), and the second will

    Full Text Available Annualy renewed resources of drinking water on the Earth are about 45000 cu. km. With today's stage of development that quantity is enough for living 4.5 to 9 billion of people. As it is expected that by 2025 the population on our planet will be over 8.5 billion people, it is clear that the next century will be characterized by the problem of ensuring enaugh quantities of drinking water. This problem will be particularly emphasized in the developing countries and large cities. In the poor countries of arid and subarid areas water deficit will cause the food production crisis and large migrations of the population with almost unpredistable sociological, economical and political consequences could be expected. In the developed world the "water crisis" will stimulate scientific and tehnological progress. The Republic of Croatia, if examined as a whole, regarding the climatic, hydrological, hydrogeological and demographic conditions, has planty of good quality water. It is our duty to preserve this resources for future generations (the paper is published in Croatian.

  9. Accelerated Capacity Development in Water Resources Education: the experiences of the Ethiopian Institute of Water Resources (United States)

    Alamirew, T.; Mekonnen, G.; Viglione, A.


    Ethiopia recently recognises that the water resources development is the major entry point in poverty alleviation and sustainable development. Water in Ethiopia plays a key role in the Water-Energy-Food-nexus. Over 98% of the electricity in the country is generated using hydropower and yet about 2000 MW has been developed. Out of the 3.5 Mha potentially irrigable land, only 0.25 Mha has been developed to date. Access to drinking water supply coverage is among the lowest in the world. One of the limiting factors in harnessing the resource base is the absence of water professionals to face the fast growing demand in education, research, development in the water sector. Recognising this, in collaboration with University of Connecticut of the United States, Addis Ababa University launched the Ethiopian Institute of Water Resources (EIWR) by enrolling 18 PhD and 24 MSc students. The program is unique in that much of the course instructors are coming from US and European Universities, but deliver courses together with Ethiopian collaborators. This is supposed to facilitate knowledge and experience transfer from the US/EU scientist to Ethiopian counterparts. The theses/dissertations are designed to focus on Ethiopia's immediate hydrological problems on selected basins, and will be coordinated by three advisors for each PhD - one from US/EU, one from Ethiopian Universities, and one water professional from the sector. We report here the lessons learned in setting up the EIWR institute and the education program.

  15. Managed Aquifer Recharge (MAR in Sustainable Urban Water Management

    Directory of Open Access Journals (Sweden)

    Declan Page


    Full Text Available To meet increasing urban water requirements in a sustainable way, there is a need to diversify future sources of supply and storage. However, to date, there has been a lag in the uptake of managed aquifer recharge (MAR for diversifying water sources in urban areas. This study draws on examples of the use of MAR as an approach to support sustainable urban water management. Recharged water may be sourced from a variety of sources and in urban centers, MAR provides a means to recycle underutilized urban storm water and treated wastewater to maximize their water resource potential and to minimize any detrimental effects associated with their disposal. The number, diversity and scale of urban MAR projects is growing internationally due to water shortages, fewer available dam sites, high evaporative losses from surface storages, and lower costs compared with alternatives where the conditions are favorable, including water treatment. Water quality improvements during aquifer storage are increasingly being documented at demonstration sites and more recently, full-scale operational urban schemes. This growing body of knowledge allows more confidence in understanding the potential role of aquifers in water treatment for regulators. In urban areas, confined aquifers provide better protection for waters recharged via wells to supplement potable water supplies. However, unconfined aquifers may generally be used for nonpotable purposes to substitute for municipal water supplies and, in some cases, provide adequate protection for recovery as potable water. The barriers to MAR adoption as part of sustainable urban water management include lack of awareness of recent developments and a lack of transparency in costs, but most importantly the often fragmented nature of urban water resources and environmental management.

  17. Sustainable River Water Quality Management in Malaysia

    Directory of Open Access Journals (Sweden)

    Abdullah Al-Mamun


    Full Text Available Ecological status of Malaysia is not as bad as many other developing nations in the world. However, despite the enforcement of the Environmental Quality Act (EQA in 1974, the water quality of Malaysian inland water (especially rivers is following deteriorating trend. The rivers are mainly polluted due to the point and non-point pollution sources. Point sources are monitored and controlled by the Department of Environment (DOE, whereas a significant amount of pollutants is contributed by untreated sullage and storm runoff. Nevertheless, it is not too late to take some bold steps for the effective control of non-point source pollution and untreated sullage discharge, which play significant roles on the status of the rivers. This paper reviews the existing procedures and guidelines related to protection of the river water quality in Malaysia.  There is a good possibility that the sewage and effluent discharge limits in the Environmental Quality Act (EQA may pose hindrance against achieving good quality water in the rivers as required by the National Water Quality Standards (NWQS. For instance, Ammoniacal Nitrogen (NH3-N is identified as one of the main pollutants to render many of the rivers polluted but it was not considered in the EQA as a monitoring parameter until the new regulations published in 2009.  Surprisingly, the new regulation for sewage and industrial effluent limits set allowable NH3-N concentration quite high (5 mg/L, which may result in low Water Quality Index (WQI values for the river water. The water environment is a dynamic system. Periodical review of the monitoring requirements, detecting emerging pollutants in sewage, effluent and runoff, and proper revision of water quality standards are necessary for the management of sustainable water resources in the country.

    Full Text Available The study of problem associated with water availability and its mapping is due to the need to solve urgent water problems of the Russian regions for their sustainable development. At the same time, sustainability is understood as rational use of water resources and their conservation to maintain the ecological balance of territories, and water security of regions is evaluated from the standpoint of water supply to municipalities. The shortage of water resources in Russia is perceived skeptically since our country is rich in water resources and the scarcity of fresh water threatens only a small part of its territory. However, the experts consider [Danilov-Danilyan, Galfan, 2015] that such a myopic point of view can lead in the long term to emergencies. The potential danger and risk of water use are already typical for the areas, which experience water stress. These are the territories with extremely low water availability per capita, less than 1.0-2.0 thousand m3/person/year [Shiklomanov, 2000; Danilov-Danilyan, Losev, 2006]. Geoinformation-cartographic modeling allows to differentiate the area under study according to water resource potential, to identify municipalities with low water availability and to estimate the population living in the area of potential danger and risk of water use.

    Renard Yung Jhien Siew


    Full Text Available While environmental sustainability has been the subject of much debate in the last decade, it was not until recently that attention started to shift towards human resource management as an enabler for sustainability.  Yet, this is still a relatively under researched area.  Much is still unknown about the role of an individual worker in contributing towards sustainable development.  This paper addresses the gap by proposing a framework to measure sustainability competencies of employees within the construction industry sector.  As part of the framework, four proficiency levels together with relevant descriptions are defined for a total of eight sustainability competencies.  Suggested proficiency levels are then mapped to main construction related jobs based on the framework.  An example is also given to illustrate the manner in which competencies should be assessed.  This framework is original and of practical use to construction managers and human resource practitioners.

  3. Technological innovation and developmental strategies for sustainable management of aquatic resources in developing countries. (United States)

    Agboola, Julius Ibukun


    Sustainable use and allocation of aquatic resources including water resources require implementation of ecologically appropriate technologies, efficient and relevant to local needs. Despite the numerous international agreements and provisions on transfer of technology, this has not been successfully achieved in developing countries. While reviewing some challenges to technological innovations and developments (TID), this paper analyzes five TID strategic approaches centered on grassroots technology development and provision of localized capacity for sustainable aquatic resources management. Three case studies provide examples of successful implementation of these strategies. Success requires the provision of localized capacity to manage technology through knowledge empowerment in rural communities situated within a framework of clear national priorities for technology development.

  7. Water resources. [mapping and management (United States)

    Salomonson, V. V.


    Substantial progress has been made in applying ERTS-1 data to water resources problems, nevertheless, more time and effort still appear necessary for further quantification of results, including the specification of thematic measurement accuracies. More modeling can be done very profitably. In particular, more strategy models describing the processes wherein ERTS-1 data would be acquired, analyzed, processed, and utilized in operational situations could be profitably accomplished. It is generally observed that the ERTS-1 data applicability is evident in several areas and that the next most general and substantive steps in the implementation of the data in operational situations would be greatly encouraged by the establishment of an operational earth resources satellite organization and capability. Further encouragement of this operational capability would be facilitated by all investigators striving to document their procedures as fully as possible and by providing time and cost comparisons between ERTS-1 and conventional acquisition approaches.

  10. Sustainable water use and management options in a water-stressed river basin in Kenya (United States)

    Hirpa, Feyera; Dadson, Simon; Dyer, Ellen; Barbour, Emily; Charles, Katrina; Hope, Robert


    Sustainable water resource is critical for maintaining healthy ecosystems and supporting socio-economic sectors. Hydro-climatic change and variability, population growth as well as new infrastructure developments create water security risks. Therefore, evidence-based management decisions are necessary to improve water security and meet the future water demands of multiple competing sectors. In this work we perform water resource modelling in order to investigate the impact of increasing water demand (expanding agriculture, booming industry, growing population) on the sustainable water use in Turkwel river basin, located in arid north-western Kenya. We test different management options to determine those that meet the water demands of the concerned sectors whilst minimising environmental impact. We perform scenario analysis using Water Evaluation And Planning (WEAP) model to explore different ranges of climate conditions, population growth rates, irrigation scale, reservoir operations, and economic development. The results can be used as a scientific guideline for the policy makers who decide the alternative management options that ensure the sustainable water use in the basin. The work is part of the REACH - improving water security for the poor program (, aiming to support a pathway to sustainable growth and poverty reduction

  11. Water resources assessment and prediction in China

    Directory of Open Access Journals (Sweden)

    W. Guangsheng


    Full Text Available Water resources assessment in China, can be classified into three groups: (i comprehensive water resources assessment, (ii annual water resources assessment, and (iii industrial project water resources assessment. Comprehensive water resources assessment is the conventional assessment where the frequency distribution of water resources in basins or provincial regions are analyzed. For the annual water resources assessment, water resources of the last year in basins or provincial regions are usually assessed. For the industrial project water resources assessment, the water resources situation before the construction of industrial project has to be assessed. To address the climate and environmental changes, hydrological and statistical models are widely applied for studies on assessing water resources changes. For the water resources prediction in China usually the monthly runoff prediction is used. In most low flow seasons, the flow recession curve is commonly used as prediction method. In the humid regions, the rainfall-runoff ensemble prediction (ESP has been widely applied for the monthly runoff prediction. The conditional probability method for the monthly runoff prediction was also applied to assess next month runoff probability under a fixed initial condition.

  12. Urban water sustainability: framework and application

    Directory of Open Access Journals (Sweden)

    Wu Yang


    Full Text Available Urban areas such as megacities (those with populations greater than 10 million are hotspots of global water use and thus face intense water management challenges. Urban areas are influenced by local interactions between human and natural systems and interact with distant systems through flows of water, food, energy, people, information, and capital. However, analyses of water sustainability and the management of water flows in urban areas are often fragmented. There is a strong need to apply integrated frameworks to systematically analyze urban water dynamics and factors that influence these dynamics. We apply the framework of telecoupling (socioeconomic and environmental interactions over distances to analyze urban water issues, using Beijing as a demonstration megacity. Beijing exemplifies the global water sustainability challenge for urban settings. Like many other cities, Beijing has experienced drastic reductions in quantity and quality of both surface water and groundwater over the past several decades; it relies on the import of real and virtual water from sending systems to meet its demand for clean water, and releases polluted water to other systems (spillover systems. The integrative framework we present demonstrates the importance of considering socioeconomic and environmental interactions across telecoupled human and natural systems, which include not only Beijing (the water-receiving system but also water-sending systems and spillover systems. This framework helps integrate important components of local and distant human-nature interactions and incorporates a wide range of local couplings and telecouplings that affect water dynamics, which in turn generate significant socioeconomic and environmental consequences, including feedback effects. The application of the framework to Beijing reveals many research gaps and management needs. We also provide a foundation to apply the telecoupling framework to better understand and manage water

  13. Payments for Ecosystem Services for watershed water resource allocations (United States)

    Fu, Yicheng; Zhang, Jian; Zhang, Chunling; Zang, Wenbin; Guo, Wenxian; Qian, Zhan; Liu, Laisheng; Zhao, Jinyong; Feng, Jian


    Watershed water resource allocation focuses on concrete aspects of the sustainable management of Ecosystem Services (ES) that are related to water and examines the possibility of implementing Payment for Ecosystem Services (PES) for water ES. PES can be executed to satisfy both economic and environmental objectives and demands. Considering the importance of calculating PES schemes at the social equity and cooperative game (CG) levels, to quantitatively solve multi-objective problems, a water resources allocation model and multi-objective optimization are provided. The model consists of three modules that address the following processes: ① social equity mechanisms used to study water consumer associations, ② an optimal decision-making process based on variable intervals and CG theory, and ③ the use of Shapley values of CGs for profit maximization. The effectiveness of the proposed methodology for realizing sustainable development was examined. First, an optimization model with water allocation objective was developed based on sustainable water resources allocation framework that maximizes the net benefit of water use. Then, to meet water quality requirements, PES cost was estimated using trade-off curves among different pollution emission concentration permissions. Finally, to achieve equity and supply sufficient incentives for water resources protection, CG theory approaches were utilized to reallocate PES benefits. The potential of the developed model was examined by its application to a case study in the Yongding River watershed of China. Approximately 128 Mm3 of water flowed from the upper reach (Shanxi and Hebei Provinces) sections of the Yongding River to the lower reach (Beijing) in 2013. According to the calculated results, Beijing should pay USD6.31 M (¥39.03 M) for water-related ES to Shanxi and Hebei Provinces. The results reveal that the proposed methodology is an available tool that can be used for sustainable development with resolving PES

  14. Is light water reactor technology sustainable?

    Energy Technology Data Exchange (ETDEWEB)

    Rothwell, G. [Stanford Univ., Dept. of Economics, CA (United States); Van der Zwaan, B. [Vrije Univ., Amsterdam, Inst. for Environmental Studies (Netherlands)


    This paper proposes criteria for determining ''intermediate sustainability'' over a 500-year horizon. We apply these criteria to Light Water Reactor (LWR) technology and the LWR industry. We conclude that LWR technology does not violate intermediate sustainability criteria for (1) environmental externalities, (2) worker and public health and safety, or (3) accidental radioactive release. However, it does not meet criteria to (1) efficiently use depleted uranium and (2) avoid uranium enrichment technologies that can lead to nuclear weapons proliferation. Finally, current and future global demand for LWR technology might be below the minimum needed to sustain the current global LWR industry. (author)

  16. Sustainable Water Distribution Strategy with Smart Water Grid

    Directory of Open Access Journals (Sweden)

    Seongjoon Byeon


    Full Text Available Many problems that are encountered in regards to water balance and resources management are related to challenges of economic development under limited resources and tough competition among various water uses. The development of major infrastructure like airports in remote areas that have limited water resources is becoming a common problem. In order to overcome these difficulties, water management has to articulate and combine several resources in order to respond to various demands while preserving the ecological quality of the environment. The paper discusses the interest in implementing the Smart Water Grid concept on Yeongjongdo Island, which is the location of Korea’s main airport. This new concept is based on the connection of various water resources and their optimized management with new information technology solutions. The proposed system integrates water generated through rainfall, external water resources (i.e., metropolitan water distribution system, gray water and other types of alternative water resources. The paper analyses the feasibility of this approach and explores interest in the Smart Water Grid concept.

  17. Incorporating permaculture and strategic management for sustainable ecological resource management. (United States)

    Akhtar, Faiza; Lodhi, Suleman A; Khan, Safdar Shah; Sarwar, Farhana


    Utilization of natural assets to the best efficient level without changing natural balance has become a critical issue for researchers as awareness on climate change takes central position in global debate. Conventional sustainable resource management systems are based on neoclassical economic approach that ignores the nature's pattern and therefore are not actually capable of sustainable management of resources. Environmentalists are lately advocating incorporation of Permaculture as holistic approach based on ethics, equitable interaction with eco-systems to obtain sustainability. The paper integrates philosophy of permaculture with strategic management frameworks to develop a pragmatic tool for policy development. The policy design tool augments management tasks by integrating recording of natural assets, monitoring of key performance indicators and integration of sectorial policies in real time, bringing out policy as a truly live document. The tool enhances the edifice process, balancing short term viewpoints and long term development to secure renewability of natural resources. Copyright © 2016 Elsevier Ltd. All rights reserved.

  18. Sustainability Investigation of Resource-Based Cities in Northeastern China

    Directory of Open Access Journals (Sweden)

    Chengpeng Lu


    Full Text Available Improving the sustainability of traditional resource-based cities in China has been a core issue and policy-priority for Chinese government to establish long-term ecological civilization, particularly for northeastern China which is recognized as a typical agglomeration area of resources cities. In this study, we establish a three-layer index system consisting of a comprehensive layer, systemic layer, and variable layer, and including 22 indicators which are grouped into economic, social and environmental subsystems. After that, the TOPSIS (Technique for Order Preference by Similarity to Ideal Solution method was applied to measure and rank the sustainability of the selected 15 typical resource-based cities in northeast China, and then a GIS (Geographical Information System technique based on the software of SuperMap was applied to map the sustainability in terms of the spatial effects among these cities. The results reveal that a unilateral improvement of a subsystem did not mean an improvement or contribution to whole system. In detail, during the past 15 years from 2000 to 2015, the comprehensive sustainability of resource-based cities in Northeastern China shows a declining trend in the mass, and the sustainability of the economic subsystem shows increase; the sustainability of the social system remains stable, while the environmental subsystem shows decrease. These situations might result from policy interventions during the past 15 years, therefore, promoting the sustainability of resource-based cities needs a historical approach, which should focus on the coordinated development of its economic, social, and environmental subsystems.

  19. How Does Scale of Implementation Impact the Environmental Sustainability of Wastewater Treatment Integrated with Resource Recovery? (United States)

    Cornejo, Pablo K; Zhang, Qiong; Mihelcic, James R


    Energy and resource consumptions required to treat and transport wastewater have led to efforts to improve the environmental sustainability of wastewater treatment plants (WWTPs). Resource recovery can reduce the environmental impact of these systems; however, limited research has considered how the scale of implementation impacts the sustainability of WWTPs integrated with resource recovery. Accordingly, this research uses life cycle assessment (LCA) to evaluate how the scale of implementation impacts the environmental sustainability of wastewater treatment integrated with water reuse, energy recovery, and nutrient recycling. Three systems were selected: a septic tank with aerobic treatment at the household scale, an advanced water reclamation facility at the community scale, and an advanced water reclamation facility at the city scale. Three sustainability indicators were considered: embodied energy, carbon footprint, and eutrophication potential. This study determined that as with economies of scale, there are benefits to centralization of WWTPs with resource recovery in terms of embodied energy and carbon footprint; however, the community scale was shown to have the lowest eutrophication potential. Additionally, technology selection, nutrient control practices, system layout, and topographical conditions may have a larger impact on environmental sustainability than the implementation scale in some cases.

  20. Evaluating Water Management Practice for Sustainable Mining

    Directory of Open Access Journals (Sweden)

    Xiangfeng Zhang


    Full Text Available To move towards sustainable development, the mining industry needs to identify better mine water management practices for reducing raw water use, increasing water use efficiency, and eliminating environmental impacts in a precondition of securing mining production. However, the selection of optimal mine water management practices is technically challenging due to the lack of scientific tools to comprehensively evaluate management options against a set of conflicting criteria. This work has provided a solution to aid the identification of more sustainable mine water management practices. The solution includes a conceptual framework for forming a decision hierarchy; an evaluation method for assessing mine water management practices; and a sensitivity analysis in view of different preferences of stakeholders or managers. The solution is applied to a case study of the evaluation of sustainable water management practices in 16 mines located in the Bowen Basin in Queensland, Australia. The evaluation results illustrate the usefulness of the proposed solution. A sensitivity analysis is performed according to preference weights of stakeholders or managers. Some measures are provided for assessing sensitivity of strategy ranking outcomes if the weight of an indicator changes. Finally, some advice is given to improve the mine water management in some mines.

  2. Learning about water resource sharing through game play

    Directory of Open Access Journals (Sweden)

    T. Ewen


    Full Text Available Games are an optimal way to teach about water resource sharing, as they allow real-world scenarios to be enacted. Both students and professionals learning about water resource management can benefit from playing games, through the process of understanding both the complexity of sharing of resources between different groups and decision outcomes. Here we address how games can be used to teach about water resource sharing, through both playing and developing water games. An evaluation of using the web-based game Irrigania in the classroom setting, supported by feedback from several educators who have used Irrigania to teach about the sustainable use of water resources, and decision making, at university and high school levels, finds Irrigania to be an effective and easy tool to incorporate into a curriculum. The development of two water games in a course for masters students in geography is also presented as a way to teach and communicate about water resource sharing. Through game development, students learned soft skills, including critical thinking, problem solving, team work, and time management, and overall the process was found to be an effective way to learn about water resource decision outcomes. This paper concludes with a discussion of learning outcomes from both playing and developing water games.

  8. Behind the sacred tree: local people and their natural resources sustain-ability

    Directory of Open Access Journals (Sweden)

    Mohammad Royyani


    Full Text Available Local communities have their own means of maintaining their traditional know-ledge and sustaining the production system of natural resources by designating the resources as sacred. Without the state’s influence, local people have their own strategies to conserve the environment and resources, in ways which are more effective than those enforced by the state. A study done through interview, participatory observation, and ethnographic methods revealed that local people recognized two models of natural resources conservation. The first model is the designation of forests as sacred site, aiming at maintaining the sustainability of ecosystem and the second model refers to adoption of species as a sacred entity to sustain production system. Dynamic processes are operating in the sacredness of both forest and species.

  10. Adapting water accounting for integrated water resource management. The Júcar Water Resource System (Spain) (United States)

    Momblanch, Andrea; Andreu, Joaquín; Paredes-Arquiola, Javier; Solera, Abel; Pedro-Monzonís, María


    An increase in water demands, exacerbated by climate change and the tightening of environmental requirements, leads to a reduction in available water resources for economic uses. This situation poses challenges for water resource planning and management. Water accounting has emerged as an appropriate tool to improve transparency and control in water management. There are multiple water accounting approaches, but they generally involve a very exhaustive list of accounted concepts. According to our findings in this research, one of the best water accounting methodologies is the Australian Water Accounting Standard. However, its implementation for integrated water resource planning and management purposes calls into questioning the amount of information and level of detail necessary for the users of water accounts. In this paper, we present a different method of applying the Australian Water Accounting Standard in relation to water resource management, which improves its utility. In order to compare the original approach and that proposed here, we present and discuss an application to the Júcar Water Resource System, in eastern Spain.

  11. A New Framework for Assessing the Sustainability Reporting Disclosure of Water Utilities

    Directory of Open Access Journals (Sweden)

    Silvia Cantele


    Full Text Available Sustainability reporting is becoming more and more widespread among companies aiming at disclosing their contribution to sustainable development and gaining legitimacy from stakeholders. This is more significant for firms operating in a public services’ context and mainly when supplying a fundamental public resource, like water utilities. While the literature on sustainability reporting in the water sector is scant, there is an increasing need to study the usefulness and quality of its sustainability disclosures to adequately inform the stakeholders about the activities of water utilities to protect this fundamental resource and general sustainable development. This article presents a novel assessment framework based on a scoring technique and an empirical analysis on the sustainability reports of Italian water utilities carried out through it. The results highlight a low level of disclosure on the sustainability indicators suggested by the main sustainability reporting guidelines (Global Reporting Initiative, (GRI, and Sustainability Accounting Standard Board, (SASB; most companies tend to disclose only qualitative information and fail to inform about some material aspects of water management, such as water recycled, network resilience, water sources, and effluent quality. These findings indicate that sustainability reporting is mainly considered as a communication tool, rather than a performance measurement and an accountability tool, but also suggest the need for a new and international industry-specific sustainability reporting standard.

  14. An Integrated Assessment of Investments towards Global Water Sustainability

    Directory of Open Access Journals (Sweden)

    Andrea M. Bassi


    Full Text Available To date there has been limited research on integrated water resource management, specifically regarding investments, from a global perspective, largely due to the complexity of the problem and to generally local water management practices. Water demand and supply are very often affected by international factors and with global climate change, population growth and increasing consumption, water management is now more than ever a global issue. This paper gives an overview of current and impending water problems while assessing investment needs for integrated water management as a possible solution to projected water challenges. The analysis compares a business as usual case (BAU to a scenario in which investments improve water efficiency use across sectors to curb demand, increase innovative supply from desalination and enhance conventional water resources management measures. System dynamics modeling is employed to represent the structural factors influencing water demand and supply in the context of an integrated framework including cross-sectoral linkages. The analysis confirms that sustainable water management is feasible, but it requires investments in the range of $145 billion per year between 2011 and 2050 (0.16% of GDP or $17/person/year and timely, effective action.

  1. Sustainable development and the exploitation of mineral and energy resources: a review (United States)

    Wellmer, F.-W.; Becker-Platen, J. D.


    Natural resources, e.g., metals, industrial minerals, water, and soil, are the essential basis for our economy and well-being. We have to know where these raw materials come from and how they are mined. Sustainable development requires the maintenance, rational use and enhancement of natural resources, as well as a balanced consideration of ecology, economy and social justice. Four general rules concerning the implementation of sustainable development for renewable and non-renewable resources are discussed. Examples of the consumption of selected materials from historical times to the present day are presented, as well as of regional distribution, usage (in contrast to consumption), lifetimes of resources, the supply-and-demand cycle, recycling and substitution in modern times. To fulfill the requirement of sustainable development, the efficiency with which resources are utilized has to be improved. The learning process, often driven by financial rewards, leads from one technology to a better one, thus increasing the efficiency of the use of a resource or commodity. Examples of learning curves are discussed. Industrial countries have to transfer their advanced technologies to developing countries in order to avoid undesirable development in the mining industry and use of natural resources in those regions. The use of the best available technology by the mining industry, taking into account economic considerations, and the necessity to establish environmental guidelines are essential if environmental impact of the production of non-renewable resources is to be minimized. Far more critical than the production of non-renewable resources under the aspect of sustainable development and the capacity of the pollutant sinks of the Earth is the element of natural attenuation with regard to the resources soil and water.

  2. Balancing water resource conservation and food security in China. (United States)

    Dalin, Carole; Qiu, Huanguang; Hanasaki, Naota; Mauzerall, Denise L; Rodriguez-Iturbe, Ignacio


    China's economic growth is expected to continue into the next decades, accompanied by sustained urbanization and industrialization. The associated increase in demand for land, water resources, and rich foods will deepen the challenge of sustainably feeding the population and balancing agricultural and environmental policies. We combine a hydrologic model with an economic model to project China's future food trade patterns and embedded water resources by 2030 and to analyze the effects of targeted irrigation reductions on this system, notably on national agricultural water consumption and food self-sufficiency. We simulate interprovincial and international food trade with a general equilibrium welfare model and a linear programming optimization, and we obtain province-level estimates of commodities' virtual water content with a hydrologic model. We find that reducing irrigated land in regions highly dependent on scarce river flow and nonrenewable groundwater resources, such as Inner Mongolia and the greater Beijing area, can improve the efficiency of agriculture and trade regarding water resources. It can also avoid significant consumption of irrigation water across China (up to 14.8 km(3)/y, reduction by 14%), while incurring relatively small decreases in national food self-sufficiency (e.g., by 3% for wheat). Other researchers found that a national, rather than local, water policy would have similar effects on food production but would only reduce irrigation water consumption by 5%.

  9. Sustainability of water-supply at military installations, Kabul Basin, Afghanistan (United States)

    Mack, Thomas J.; Chornack, Michael P.; Verstraeten, Ingrid M.; Linkov, Igor


    The Kabul Basin, including the city of Kabul, Afghanistan, is host to several military installations of Afghanistan, the United States, and other nations that depend on groundwater resources for water supply. These installations are within or close to the city of Kabul. Groundwater also is the potable supply for the approximately four million residents of Kabul. The sustainability of water resources in the Kabul Basin is a concern to military operations, and Afghan water-resource managers, owing to increased water demands from a growing population and potential mining activities. This study illustrates the use of chemical and isotopic analysis, groundwater flow modeling, and hydrogeologic investigations to assess the sustainability of groundwater resources in the Kabul Basin.Water supplies for military installations in the southern Kabul Basin were found to be subject to sustainability concerns, such as the potential drying of shallow-water supply wells as a result of declining water levels. Model simulations indicate that new withdrawals from deep aquifers may have less of an impact on surrounding community water supply wells than increased withdrawals from near- surface aquifers. Higher rates of recharge in the northern Kabul Basin indicate that military installations in that part of the basin may have fewer issues with long-term water sustainability. Simulations of groundwater withdrawals may be used to evaluate different withdrawal scenarios in an effort to manage water resources in a sustainable manner in the Kabul Basin.

  10. Water Footprint Assessment in Waste Water Treatment Plant: Indicator of the sustainability of urban water cycle. (United States)

    Gómez Llanos, Eva; Durán Barroso, Pablo; Matías Sánchez, Agustín; Fernández Rodríguez, Santiago; Guzmán Caballero, Raúl


    The seventeen Sustainable Development Goals (SDG) represent a challenge for citizens and countries around the world by working together to reduce social inequality, to fight poverty and climate change. The Goal six water and sanitation aims for ensuring, among others, the protection and restoration of water-related ecosystem (target 6.6) and encouraging the water use efficiency (target 6.3). The commitment to this goal is not only the development of sanitation infrastructure, but also incorporates the necessity of a sustainable and efficient management from ecological and economic perspectives. Following this approach, we propose a framework for assessing the waste water treatment plant (WWTP) management based on the Water Footprint (WF) principles. The WF as indicator is able to highlight the beneficial role of WWTPs within the environment and provide a complementary information to evaluate the impact of a WWTP regarding to the use of freshwater and energy. Therefore, the footprint family provides an opportunity to relate the reduction of pollutant load in a WWTP and the associated consumptions in terms of electricity and chemical products. As a consequence, the new methodology allows a better understanding of the interactions among water and energy resources, economic requirements and environmental risks. Because of this, the current technologies can be improved and innovative solutions for monitoring and management of urban water use can be integrated. The WF was calculated in four different WWTP located in the North East of Extremadura (SW Spain) which have activated sludge process as secondary treatment. This zone is characterized by low population density but an incipient tourism development. The WF estimation and its relationship with the electricity consumption examines the efficiency of each WWTP and identifies the weak points in the management in terms of the sustainability. Consequently, the WF establishes a benchmark for multidisciplinary decision

  15. Sustainability Learning in Natural Resource Use and Management

    Directory of Open Access Journals (Sweden)

    J. David Tàbara


    Full Text Available We contribute to the normative discussion on sustainability learning and provide a theoretical integrative framework intended to underlie the main components and interrelations of what learning is required for social learning to become sustainability learning. We demonstrate how this framework has been operationalized in a participatory modeling interface to support processes of natural resource integrated assessment and management. The key modeling components of our view are: structure (S, energy and resources (E, information and knowledge (I, social-ecological change (C, and the size, thresholds, and connections of different social-ecological systems. Our approach attempts to overcome many of the cultural dualisms that exist in the way social and ecological systems are perceived and affect many of the most common definitions of sustainability. Our approach also emphasizes the issue of limits within a total social-ecological system and takes a multiscale, agent-based perspective. Sustainability learning is different from social learning insofar as not all of the outcomes of social learning processes necessarily improve what we consider as essential for the long-term sustainability of social-ecological systems, namely, the co-adaptive systemic capacity of agents to anticipate and deal with the unintended, undesired, and irreversible negative effects of development. Hence, the main difference of sustainability learning from social learning is the content of what is learned and the criteria used to assess such content; these are necessarily related to increasing the capacity of agents to manage, in an integrative and organic way, the total social-ecological system of which they form a part. The concept of sustainability learning and the SEIC social-ecological framework can be useful to assess and communicate the effectiveness of multiple agents to halt or reverse the destructive trends affecting the life-support systems upon which all humans

    Full Text Available This paper examines Resource Management as a Panacea for Sustainable National Economic Development and National Unity. The nation has been besieged by numerous problems due to poor resource management. These problems include corruption health implications poverty and inequality in income distribution ethnic crisis pollutions and it has also resulted in economic losses. These problems have militated against the countrys ability to create wealth for the present and future generation. The paper also looked at the concept of conservation and sustainability and their relationship with resource management. The main thrust of the recommendations was hinged on the problems mentioned. These recommendations include making revenue from resources more equitably distributed compensating the people of the area through the development of infrastructures like health facilities and provision of pipe borne water making and enforcing laws that will reduce pollution and development of capital projects.

  17. Measuring global water security towards sustainable development goals (United States)

    Gain, Animesh K.; Giupponi, Carlo; Wada, Yoshihide


    Water plays an important role in underpinning equitable, stable and productive societies and ecosystems. Hence, United Nations recognized ensuring water security as one (Goal 6) of the seventeen sustainable development goals (SDGs). Many international river basins are likely to experience ‘low water security’ over the coming decades. Water security is rooted not only in the physical availability of freshwater resources relative to water demand, but also on social and economic factors (e.g. sound water planning and management approaches, institutional capacity to provide water services, sustainable economic policies). Until recently, advanced tools and methods are available for the assessment of water scarcity. However, quantitative and integrated—physical and socio-economic—approaches for spatial analysis of water security at global level are not available yet. In this study, we present a spatial multi-criteria analysis framework to provide a global assessment of water security. The selected indicators are based on Goal 6 of SDGs. The term ‘security’ is conceptualized as a function of ‘availability’, ‘accessibility to services’, ‘safety and quality’, and ‘management’. The proposed global water security index (GWSI) is calculated by aggregating indicator values on a pixel-by-pixel basis, using the ordered weighted average method, which allows for the exploration of the sensitivity of final maps to different attitudes of hypothetical policy makers. Our assessment suggests that countries of Africa, South Asia and Middle East experience very low water security. Other areas of high water scarcity, such as some parts of United States, Australia and Southern Europe, show better GWSI values, due to good performance of management, safety and quality, and accessibility. The GWSI maps show the areas of the world in which integrated strategies are needed to achieve water related targets of the SDGs particularly in the African and Asian continents.

  19. Governance of urban transitions: towards sustainable resource efficient urban infrastructures (United States)

    Swilling, Mark; Hajer, Maarten


    The transition to sustainable resource efficient cities calls for new governance arrangements. The awareness that the doubling of the global urban population will result in unsustainable levels of demand for natural resources requires changes in the existing socio-technical systems. Domestic material consumption could go up from 40 billion tons in 2010, to 89 billion tons by 2050. While there are a number of socio-technical alternatives that could result in significant improvements in the resource efficiency of urban systems in developed and developing countries (specifically bus-rapid transit, district energy systems and green buildings), we need to rethink the urban governance arrangements to get to this alternative pathway. We note modes of urban governance have changed over the past century as economic and urban development paradigms have shifted at the national and global levels. This time round we identify cities as leading actors in the transition to more sustainable modes of production and consumption as articulated in the Sustainable Development Goals. This has resulted in a surge of urban experimentation across all world regions, both North and South. Building on this empirically observable trend we suggest this can also be seen as a building block of a new urban governance paradigm. An ‘entrepreneurial urban governance’ is proposed that envisages an active and goal-setting role for the state, but in ways that allows broader coalitions of urban ‘agents of change’ to emerge. This entrepreneurial urban governance fosters and promotes experimentation rather than suppressing the myriad of such initiatives across the globe, and connects to global city networks for systemic learning between cities. Experimentation needs to result in a contextually appropriate balance between economic, social, technological and sustainable development. A full and detailed elaboration of the arguments and sources for this article can be found in chapter 6 of Swilling M et

    Full Text Available Access to clean water resources has always been a crucial factor in the history of mankind. Now, in the 21st century, water, as an increasingly scarce resource, will take a strategic role for the future development of global populations. As the former UN Secretary General Dr. Dr. Boutrous Boutrous Ghali predicts: “The wars of the 21st century will be fought not over oil, they will be fought over water.” [1]. In nine global examples will be demonstrated the different ways of dealing with water resources. That are: Mexico City, Egypt, Libya, DOW Terneuzen, Los Angeles, Israel, China and Singapore and also global trends, such as, scarcity & rural exodus and salinization of soil. Thereby, he explains the different kinds of water management to be observed. The most relevant prognosis of the WHO is, that to the end of 21st century Africa's population will grow over proportionally from 1 billion now up to nearly 4 billion [9]. That is why all efforts need to be concentrated on helping Africa create a sustainable economic development. The first and by far most important strategic step is to assure access to clean water resources in the rural and mostly arid regions of the continent. The lecturer shows several technological proposals on how to overcame problems like: water scarcity, rural exodus, salinization of soil and others. Such technologies could be successfully implemented in sustainable development programs in African countries.

    Energy Technology Data Exchange (ETDEWEB)

    Tao, W. C., LLNL


    Recent droughts in California have highlighted and refocused attention on the problem of providing reliable sources of water to sustain the State`s future economic development. Specific elements of concern include not only the stability and availability of future water supplies in the State, but also how current surface and groundwater storage and distribution systems may be more effectively managed and upgraded, how treated wastewater may be more widely recycled, and how legislative and regulatory processes may be used or modified to address conflicts between advocates of urban growth, industrial, agricultural, and environmental concerns. California is not alone with respect to these issues. They are clearly relevant throughout the West, and are becoming more so in other parts of the US. They have become increasingly important in developing and highly populated nations such as China, India, and Mexico. They are critically important in the Middle East and Southeast Asia, especially as they relate to regional stability and security issues. Indeed, in almost all cases, there are underlying themes of `reliability` and `sustainability` that pertain to the assurance of current and future water supplies, as well as a broader set of `stability` and `security` issues that relate to these assurances--or lack thereof--to the political and economic future of various countries and regions. In this latter sense, and with respect to regions such as China, the Middle East, and Southeast Asia, water resource issues may take on a very serious strategic nature, one that is most illustrative and central to the emerging notion of `environmental security.` In this report, we have identified a suite of technical tools that, when developed and integrated together, may prove effective in providing regional governments the ability to manage their water resources. Our goal is to formulate a framework for an Integrated Systems Analysis (ISA): As a strategic planning tool for managing

  4. The efficient and sustainable use of environmental resource systems

    Energy Technology Data Exchange (ETDEWEB)

    Gerlagh, R.


    The two main questions in this study are: (1) how to represent environmental resources within a dynamic, competitive economy, and (2) how to specify environmental policies that guarantee the efficient and sustainable use of these resources, and do not require day-to-day intervention. This study is organized as follows. In Chapter 2, both types of dynamic economies (dynastic and overlapping generations or OLG) are formally specified, and existence of equilibrium is proven. In particular, attention is paid to the consequences of including exhaustible resources with amenity values. It is shown that the equilibrium paths exhibit the specific features of path-dependence. This property implies that present policies have non-diminishing effects on future welfare, and points once more to the urgency of policy interventions. Chapter 3 focuses on efficiency aspects and on the capacity of environmental resources to produce an indefinite stream of valuable services. The chapter also introduces ALICE, an applied model that has a single environmental resource that possesses three specific characteristics: the resource has non-negligible amenity value and is therefore valuable, it is exhaustible, but, if no extraction takes place, the resource produces an indefinite stream of valuable services (the amenity value). An example is provided of strictly conservationist policies that create inefficiencies, and it is shown that efficiency is restored if property rights over the resource are given to the present generation, a policy known as grandfathering. However, it is also shown that, compared to the strictly conservationist policy, grandfathering improves welfare of the present generation while reducing it for future generations. Indeed, an unsustainable equilibrium path cannot be ruled out. Next, parameters are chosen such that the numerical outcomes of the stylized model become comparable with those of existing integrated assessment models that include climate change. The

  5. Impact of future energy policy on water resources in Kazakhstan (United States)

    Rivotti, Pedro; Karatayev, Marat; Sobral Mourão, Zenaida; Shah, Nilay; Clarke, Michèle; Konadu, D. Dennis


    As part of its commitment to become one of the top-30 developed countries in the world, Kazakhstan set out an ambitious target of increasing the share of renewables and alternative sources of energy in its power generation mix to 50% by 2050. This vision greatly contrasts with the current situation, with coal and natural gas power plants producing around 90% of total electricity in 2016. While this transition provides a unique opportunity to improve the sustainability of the national energy system, major natural resources challenges currently faced in the country should be taken into account. Particularly in the case of water resources management, the current system is characterised by significant losses, heavy reliance on irrigation for the agricultural sector, unevenly distributed surface water, vulnerability to climate change and variations in transboundary inflows, amongst other issues. In this context, this study aims to investigate the future availability of water resources to support food production and the transition to a new energy system. Given the challenges mentioned above, tackling this question requires an integrated analysis of the water-energy-food systems in Kazakhstan. This is done in three stages: (1) characterising the water supply and demand in the country; (2) establishing the linkages between water resources and activities in the power production and agricultural sectors; and (3) identifying potential conflicts at the nexus between water, energy and food, taking into account future energy policy scenarios, trends for food production and water resource use.

  6. Water resources of King County, Washington (United States)

    Richardson, Donald; Bingham, J.W.; Madison, R.J.; Williams, R.


    Although the total supply of water in King County is large, water problems are inevitable because of the large and rapidly expanding population. The county contains a third of the 3 million people in Washington, most of the population being concentrated in the Seattle metropolitan area. King County includes parts of two major physiographic features: the western area is part of the Puget Sound Lowland, and the eastern area is part of the Cascade Range. In these two areas, the terrain, weather, and natural resources (including water) contrast markedly. Average annual precipitation in the county is about 80 inches, ranging from about 30 inches near Puget Sound to more than 150 inches in parts of the Cascades. Annual evapotranspiration is estimated to range from 15 to 24 inches. Average annual runoff ranges from about 15 inches in the lowlands to more than 100 inches in the mountains. Most of the streamflow is in the major basins of the county--the Green-Duwamish, Lake Washington, and Snoqualmie basins. The largest of these is the Snoqualmie River basin (693 square miles), where average annual runoff during the period 1931-60 was about 79 inches. During the same period, annual runoff in the Lake Washington basin ( 607 square miles) averaged about 32 inches, and in the Green-Duwamish River basin (483 square miles), about 46 inches. Seasonal runoff is generally characterized by several high-flow periods in the winter, medium flows in the spring, and sustained low flows in the summer and fall. When floods occur in the county they come almost exclusively between October and March. The threat of flood damage is greatest on the flood plaits of the larger rivers, but in the Green-Duwamish Valley the threat was greatly reduced with the completion of Howard A. Hanson Dam in 1962. In the Snoqualmie River basin, where no such dam exists, the potential damage from a major flood increases each year as additional land is developed in the Snoqualmie Valley. 0nly moderate amounts of

  7. Virtual Water and Water Footprints: Overreaching Into the Discourse on Sustainability, Efficiency, and Equity

    Directory of Open Access Journals (Sweden)

    Dennis Wichelns


    Full Text Available The notions of virtual water and water footprints were introduced originally to bring attention to the large amounts of water required to produce crops and livestock. Recently, several authors have begun applying those notions in efforts to describe efficiency, equity, and the sustainability of resources and production activities. In this paper, I describe why the notions of virtual water and water footprints are not appropriate for analysing issues pertaining to those topics. Both notions lack a supporting conceptual framework and they contain too little information to enhance understanding of important policy issues. Neither notion accounts for the opportunity cost or scarcity value of water in any setting, or the impacts of water availability and use on livelihoods. In addition, countries trade in goods and services – not in crop and livestock water requirements. Thus, the notions of virtual water and water footprints cannot provide helpful insight regarding the sustainability of water use, economic efficiency, or social equity. Gaining such insight requires the application of legitimate conceptual frameworks, representing a broad range of perspectives from the physical and social sciences, with due consideration of dynamics, uncertainty, and the impacts of policy choices on livelihoods and natural resources.

    As we transition from fossil fuel reliance to a new energy future, innovative microbial biotechnologies may offer new routes to maximize recovery from conventional and unconventional energy assets; as well as contributing to reduced emission pathways and new technologies for carbon capture and utilization. Here we discuss the role of microbiology in petroleum biotechnologies in relation to addressing UN Sustainable Development Goal 12 (ensure sustainable consumption and production patterns), with a focus on microbially-mediated energy recovery from unconventionals (heavy oil to methane), shale gas and fracking, bioelectrochemical systems for the production of electricity from fossil fuel resources, and innovations in synthetic biology. Furthermore, using wastes to support a more sustainable approach to fossil fuel extraction processes is considered as we undertake the move towards a more circular global economy. © 2017 The Authors.

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

    Directory of Open Access Journals (Sweden)

    I.V. Zamula


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

  17. Overview of the Environmental and Water Resources Institute's "Guidelines For Integrated Water Resources Management" Project

    Energy Technology Data Exchange (ETDEWEB)

    Gerald Sehlke


    Integrated Water Resources Management is a systematic approach to optimizing our understanding, control and management of water resources within a basin to meet multiple objectives. Recognition of the need for integrating water resources within basins is not unique to the Environmental and Water Resources Institute’s Integrated Water Resources Management Task Committee. Many individuals, governments and other organizations have attempted to develop holistic water resources management programs. In some cases, the results have been very effective and in other cases, valiant attempts have fallen far short of their initial goals. The intent of this Task Committee is to provide a set of guidelines that discusses the concepts, methods and tools necessary for integrating and optimizing the management of the physical resources and to optimize and integrate programs, organizations, infrastructure, and socioeconomic institutions into comprehensive water resources management programs.

  18. Water resources management in Rostov region (Russia) (United States)

    Nazarenko, O.


    Proper management of water resources leads to the development of the region. Nowadays there is an urgent problem - water shortage. Many European countries face this problem, Russia is not the excluding. In addition, there is a problem not only of water quantity, but quality as well. Although Rostov region is well provided with fresh water, the water resources are unevenly disturbed within region. Rostov region is heavily populated and receive moderate rainfall. Groundwater has a limited capacity for renewal. At the same time, Rostov region is industrial and agricultural one that is why pressures from agriculture, industry and domestic users affect the quantity of water resources. Both water quality and availability must be integrated in long-term planning and policy implications concerning water management. In Russia there are high standards for water quality. Effectively managed water-supply and resource protection systems generate the indispensable basis for agricultural and industrial production. Throughout the Region, urban and rural development has thrived where water sources have been effectively managed. Rostov region can be divided into three parts: northern districts, central part of the region and southern ones. Main cities in the region have not enough available drinking water. In the region ground water is used for curing and water supplying purpose.

  19. Bringing ecosystem services into integrated water resources management. (United States)

    Liu, Shuang; Crossman, Neville D; Nolan, Martin; Ghirmay, Hiyoba


    In this paper we propose an ecosystem service framework to support integrated water resource management and apply it to the Murray-Darling Basin in Australia. Water resources in the Murray-Darling Basin have been over-allocated for irrigation use with the consequent degradation of freshwater ecosystems. In line with integrated water resource management principles, Australian Government reforms are reducing the amount of water diverted for irrigation to improve ecosystem health. However, limited understanding of the broader benefits and trade-offs associated with reducing irrigation diversions has hampered the planning process supporting this reform. Ecosystem services offer an integrative framework to identify the broader benefits associated with integrated water resource management in the Murray-Darling Basin, thereby providing support for the Government to reform decision-making. We conducted a multi-criteria decision analysis for ranking regional potentials to provide ecosystem services at river basin scale. We surveyed the wider public about their understanding of, and priorities for, managing ecosystem services and then integrated the results with spatially explicit indicators of ecosystem service provision. The preliminary results of this work identified the sub-catchments with the greatest potential synergies and trade-offs of ecosystem service provision under the integrated water resources management reform process. With future development, our framework could be used as a decision support tool by those grappling with the challenge of the sustainable allocation of water between irrigation and the environment.

  20. Sustainable Management of Mineral Resources-another view on criticality. (United States)

    Wellmer, F.-W.


    Generally investigations of criticality capture the supply risks on one hand and on the other hand the impact on the economy, the vulnerability to supply disruptions. The classification is a relative one and the analyses are always only a snapshot of a dynamic system: in the seventies of the last century chromium was generally considered the most critical metal. Today others are considered far more critical. These are especially the rare earth and the platinum group elements. Regardless in which direction technology develops these elements together with the steel alloy and electronic metal elements will most probably be the decisive elements to produce the high-tech products necessary for the well-being of Europe in the 21st century. These elements- often in small quantities- have a high economic lever effect. In a new research programme of the German Ministry of Education and Research they have been termed, therefore: economic-strategic raw materials. This paper will concentrate not so much on the critical materials as such, but on the factors critical in the background, critical to produce them: water, energy and the social acceptance of mining —the license to operate. From the point of sustainable management of mineral resources an important question with regard to critical aspects is also, how fast and to what extent mankind is able to reactivate the secondary materials in the technosphere to replace resource requirements from the geosphere under the limiting factors to minimize the environmental impact and energy needs. There will always be losses which have to be compensated from the geosphere (thermodynamical impossibility of a 100% closed loop, losses due to different redox potential, losses due to dispersal effects like wear and corrosion), however losses occurring today due to low scrap values can be minimized by better technology. Developments are well under way to replace more and more relative proportions of the major metal needs by material from the

  2. Resource Demand Growth and Sustainability Due to Increased World Consumption

    Directory of Open Access Journals (Sweden)

    Alexander V. Balatsky


    Full Text Available The paper aims at continuing the discussion on sustainability and attempts to forecast the impossibility of the expanding consumption worldwide due to the planet’s limited resources. As the population of China, India and other developing countries continue to increase, they would also require more natural and financial resources to sustain their growth. We coarsely estimate the volumes of these resources (energy, food, freshwater and the gross domestic product (GDP that would need to be achieved to bring the population of India and China to the current levels of consumption in the United States. We also provide estimations for potentially needed immediate growth of the world resource consumption to meet this equality requirement. Given the tight historical correlation between GDP and energy consumption, the needed increase of GDP per capita in the developing world to the levels of the U.S. would deplete explored fossil fuel reserves in less than two decades. These estimates predict that the world economy would need to find a development model where growth would be achieved without heavy dependence on fossil fuels.

  3. Enabling sustainable urban water management through governance experimentation. (United States)

    Bos, J J; Brown, R R; Farrelly, M A; de Haan, F J


    A shift towards sustainable urban water management is widely advocated but poorly understood. There is a growing body of literature claiming that social learning is of high importance in restructuring conventional systems. In particular, governance experimentation, which explicitly aims for social learning, has been suggested as an approach for enabling the translation of sustainability ideas into practice. This type of experimentation requires a very different dynamic within societal relations and necessitates a changed role for professionals engaged in such a process. This empirically focused paper investigates a contemporary governance experiment, the Cooks River Sustainability Initiative, and determines its outcome in terms of enabling social learning for attaining sustainable water practice in an urban catchment. Drawing on the qualitative insights of the actors directly involved in this novel process, this paper provides evidence of changes in individual and collective understanding generated through diverse forms of social interaction. Furthermore, the research reveals perceived key-factors that foster and/or hamper the execution of this new form of experimentation, including project complexity, resource intensity and leadership. Overall, this paper highlights that, while implementation of governance experimentation in a conventional setting can be highly challenging, it can also be highly rewarding in terms of learning.

  4. Water footprint as a tool for integrated water resources management (United States)

    Aldaya, Maite; Hoekstra, Arjen


    In a context where water resources are unevenly distributed and, in some regions precipitation and drought conditions are increasing, enhanced water management is a major challenge to final consumers, businesses, water resource users, water managers and policymakers in general. By linking a large range of sectors and issues, virtual water trade and water footprint analyses provide an appropriate framework to find potential solutions and contribute to a better management of water resources. The water footprint is an indicator of freshwater use that looks not only at direct water use of a consumer or producer, but also at the indirect water use. The water footprint of a product is the volume of freshwater used to produce the product, measured over the full supply chain. It is a multi-dimensional indicator, showing water consumption volumes by source and polluted volumes by type of pollution; all components of a total water footprint are specified geographically and temporally. The water footprint breaks down into three components: the blue (volume of freshwater evaporated from surface or groundwater systems), green (water volume evaporated from rainwater stored in the soil as soil moisture) and grey water footprint (the volume of polluted water associated with the production of goods and services). Closely linked to the concept of water footprint is that of virtual water trade, which represents the amount of water embedded in traded products. Many nations save domestic water resources by importing water-intensive products and exporting commodities that are less water intensive. National water saving through the import of a product can imply saving water at a global level if the flow is from sites with high to sites with low water productivity. Virtual water trade between nations and even continents could thus be used as an instrument to improve global water use efficiency and to achieve water security in water-poor regions of the world. The virtual water trade

  7. Strategies for sustainable management of renewable resources during environmental change. (United States)

    Lindkvist, Emilie; Ekeberg, Örjan; Norberg, Jon


    As a consequence of global environmental change, management strategies that can deal with unexpected change in resource dynamics are becoming increasingly important. In this paper we undertake a novel approach to studying resource growth problems using a computational form of adaptive management to find optimal strategies for prevalent natural resource management dilemmas. We scrutinize adaptive management, or learning-by-doing, to better understand how to simultaneously manage and learn about a system when its dynamics are unknown. We study important trade-offs in decision-making with respect to choosing optimal actions (harvest efforts) for sustainable management during change. This is operationalized through an artificially intelligent model where we analyze how different trends and fluctuations in growth rates of a renewable resource affect the performance of different management strategies. Our results show that the optimal strategy for managing resources with declining growth is capable of managing resources with fluctuating or increasing growth at a negligible cost, creating in a management strategy that is both efficient and robust towards future unknown changes. To obtain this strategy, adaptive management should strive for: high learning rates to new knowledge, high valuation of future outcomes and modest exploration around what is perceived as the optimal action. © 2017 The Author(s).

  8. Learning for sustainability: participatory resource management in Cambodian fishing villages. (United States)

    Marschke, Melissa; Sinclair, A John


    Considerable attention is now being given to the role and importance of education and learning implications of participatory resource and environmental governance. The contention is that such learning has the potential to transform behaviour, and in the case of resource management, may help change current patterns in resource use towards a more sustainable social-ecological system. Our purpose is to establish the opportunities for learning afforded to those participating in local level resource management committees in two Cambodian fishing communities and consider the learning outcomes from such opportunities. Our approach was qualitative and used a case study design. The findings establish a wide range of committee resource management activities that resulted in both instrumental (e.g., learning about administrative procedures) and communicative (e.g., insights into the need to conserve mangroves) learning. It was revealed that such learning can lead to changes in behaviour at the community level (e.g., managing local waste). Our findings also indicated a number of motivators and enablers of learning such as opportunities for dialogue, leadership and the presence of declining resources.

  9. Characterizing water resources and trends of sector wise water consumptions in Saudi Arabia

    Directory of Open Access Journals (Sweden)

    Shakhawat Chowdhury


    Full Text Available Understanding of water resources and trends of water consumptions is important to offer sustainable water resources management strategy. In this research, water resources and trends of water consumptions in Saudi Arabia were investigated. The non-renewable groundwater reserves were estimated to be 259.1–760.6 billion cubic meters (BCM with an effective annual recharge of 886 million cubic meters (MCM. The total internal renewable water was estimated to be 2.4 BCM/year. Approximately 1.4 BCM/year of runoff is collected by 302 dams. The country produces approximately 1.06 BCM desalinated water annually. The wastewater treatment plants treat approximately 0.73 BCM/year of domestic wastewater from which 0.33 BCM is recycled. The water demand in 2009 was 18.51 BCM in which 83.5% were for agriculture. From 2004 to 2009, agricultural water demand was decreased by 2.5%/year, while the domestic and industrial water demands were increased by 2.1%/year and 2.2%/year, respectively. Between 1999 and 2008, domestic water subscribers were increased by 22.7%, while the annual domestic water consumption was increased from 1391 (609–2164 to 3818 (1687–7404 m3/subscriber. The industrial water demands were increased from 56 to 713 MCM/year between 1980 and 2009. Following characterization, nonlinear equations were developed to predict the domestic, industrial and agricultural water demands. The predicted water demands were within 1–10% of the historically reported values. The findings might be useful in understanding water sources, water demands and identifying new sources for sustainable water resources management.

  10. Mapping Climate Change Vulnerability Distribution of Water Resources in a Regional Water Supply System (United States)

    Liu, T.; Tung, C.; Li, M.


    In recent years, the threat of increasing frequency of extreme weather rise up human attention on climate change. It is important to know how climate change might effect regional water resources, however, there is not much information to help government understanding how climate change will effect the water resources locally. To a regional water supply system, there might be some hotspots more vulnerable to climate. For example, the water supply of some area is from the water of river. When the storm occurred, the water can't be treated due to high density of suspended sediment in the river. Then the water supply in this area is more vulnerable to climate. This study used an integrated tool - TaiWAP (Taiwan Water Resources Assessment Program) for climate change vulnerability assessment on water resources, which includes 10 GCMs output of SRES A2, A1B, B2 scenarios, weather generator, GWLF model, and Analytic Hierarchy Process (AHP) tool. A water supply system is very complex which needs dynamic modeling to determine the vulnerability distribution. This study used a system dynamics model- VENSIM connected with TaiWAP to simulate a water supply system and evaluate vulnerability of each unit in a water supply system. The vulnerable hotspots will be indicated in the system and the adaptive strategies will be applied to strengthen the local vulnerable area. The adaptive capacity will be enhanced to mitigate climate change impacts on water supply system locally to achieve sustainable water uses.

  11. A full value-chain Water Footprint Assessment to help informed decision in corporate sustainability strategies (United States)

    Zhang, Guoping; Chico Zamanilo, Daniel; Bai, Xue; Ren, Xiajing; Chen, Rong; Qin, Jun


    This study evaluated the water footprint (WF) of five production facilities along Muyuan Foodstuff Co. Ltd's (Muyuan) value chain, and assessed the sustainability and impact of their water footprints at the river catchment level. Muyuan, a large-scale, integrated pig breeder and producer in China, is keen to fulfil its corporate social responsibilities and committed to ensuring food quality and security, promoting environmental protection, and participating in catchment water resources management. Formulating corporate water related sustainability strategies, however, has been challenging. This study carried out a comprehensive Water Footprint Assessment (WFA) for Muyuan's full value chain to assist in formulating such strategies and setting up action plans with water footprint reduction targets. The study showed that that the water footprint of the supply chain, resulting from crops and crop products used in Muyuan's feed production facility is a major contributor to Muyuan's facilities' water footprint. From the perspective of the direct WF at the facilities, addressing the impact on water quality from effluents (i.e. the grey water footprint) at hog farms is a critical component of any water sustainability strategy. From the blue WF perspective, there are opportunities to reduce blue water consumption at hog farms through improved technology and implementation of best practices. The water footprint sustainability assessment in this study indicated that Muyuan operates in a catchment which is already under water stress and is a hotspot in terms of both blue water scarcity and water pollution level. The study helped identify potential water-related risks and opportunities for improving Muyuan's water use efficiency as well as ways Muyuan could contribute to sustainable water resources management in the catchment within which it operates. This is an innovative application of WFA in the livestock sector and supports the development of Muyuan's corporate water

  15. Increasing Awareness of Sustainable Water Management for Future Civil Engineers (United States)

    Ilic, Suzana; Karleusa, Barbara; Deluka-Tibljas, Aleksandra


    organised together with civil engineering students from the University of Rijeka. The aims of this field visit are: to learn about traditional water supply from an underground storage of rain water called cisterna; and to find out from inhabitants about their current water usage habits and expectations, and how these might change when they get water from the main water supply system. This joint activity has been beneficial for both groups of students. The engineering students become aware of the importance of the social aspects in designing the water supply system, while the geography students learn about the engineering challenges entailed. Both groups learn that water consumption increases with the provision of water through pipeline systems and that this needs to be taken into account in the design of water supply and management of water resources. Importantly, they learn the benefits of traditional sustainable water supply methods, which could be implemented as primary or additional sources of water supply in other areas.In summary, both groups of students develop their professional knowledge and skills as well as generic and transferable skills, which are very important for those who will continue to a career in the design and management of water systems.

  17. Environmental and natural resource implications of sustainable urban infrastructure systems (United States)

    Bergesen, Joseph D.; Suh, Sangwon; Baynes, Timothy M.; Kaviti Musango, Josephine


    As cities grow, their environmental and natural resource footprints also tend to grow to keep up with the increasing demand on essential urban services such as passenger transportation, commercial space, and thermal comfort. The urban infrastructure systems, or socio-technical systems providing these services are the major conduits through which natural resources are consumed and environmental impacts are generated. This paper aims to gauge the potential reductions in environmental and resources footprints through urban transformation, including the deployment of resource-efficient socio-technical systems and strategic densification. Using hybrid life cycle assessment approach combined with scenarios, we analyzed the greenhouse gas (GHG) emissions, water use, metal consumption and land use of selected socio-technical systems in 84 cities from the present to 2050. The socio-technical systems analyzed are: (1) bus rapid transit with electric buses, (2) green commercial buildings, and (3) district energy. We developed a baseline model for each city considering gross domestic product, population density, and climate conditions. Then, we overlaid three scenarios on top of the baseline model: (1) decarbonization of electricity, (2) aggressive deployment of resource-efficient socio-technical systems, and (3) strategic urban densification scenarios to each city and quantified their potentials in reducing the environmental and resource impacts of cities by 2050. The results show that, under the baseline scenario, the environmental and natural resource footprints of all 84 cities combined would increase 58%–116% by 2050. The resource-efficient scenario along with strategic densification, however, has the potential to curve down GHG emissions to 17% below the 2010 level in 2050. Such transformation can also limit the increase in all resource footprints to less than 23% relative to 2010. This analysis suggests that resource-efficient urban infrastructure and decarbonization

  19. Criticality of Water: Aligning Water and Mineral Resources Assessment. (United States)

    Sonderegger, Thomas; Pfister, Stephan; Hellweg, Stefanie


    The concept of criticality has been used to assess whether a resource may become a limiting factor to economic activities. It has been primarily applied to nonrenewable resources, in particular to metals. However, renewable resources such as water may also be overused and become a limiting factor. In this paper, we therefore developed a water criticality method that allows for a new, user-oriented assessment of water availability and accessibility. Comparability of criticality across resources is desirable, which is why the presented adaptation of the criticality approach to water is based on a metal criticality method, whose basic structure is maintained. With respect to the necessary adaptations to the water context, a transparent water criticality framework is proposed that may pave the way for future integrated criticality assessment of metals, water, and other resources. Water criticality scores were calculated for 159 countries subdivided into 512 geographic units for the year 2000. Results allow for a detailed analysis of criticality profiles, revealing locally specific characteristics of water criticality. This is useful for the screening of sites and their related water criticality, for indication of water related problems and possible mitigation options and water policies, and for future water scenario analysis.

  20. Conservation program works as an alternative irrigation districts in sustainable water management of agricultural use

    Directory of Open Access Journals (Sweden)

    Víctor Manuel Peinado Guevara


    Full Text Available Water scarcity is an issue of worldwide concern since it is already having an impact on social development. Mexico is not an exception to this problem because in several regions of the country are great difficulties in supplying water, primarily for agricultural use. In Sinaloa, it had been mentioned repeatedly by the media that in the Irrigation District 063, located in the northern of the state, there are problems of water scarcity, and yet there still exist difficulties in conserving the resource. More than 49% of the water used for agriculture is wasted. To resolve this problem, producers and government agencies spend significant resources for investment in water conservation. However, the results have not been entirely satisfactory because the waste is high, a situation that motivates them to study more deeply the main weaknesses that affect sustainable resource use. Farmer’s participation in the administration of water infrastructure is important, as well as providing financial resources for the conservation of water system; and participation in activities of construction and repaired of water infrastructure. Farmer’s should also plan and design strategies for water conservation. This situation requires an appropriate level of technology and intellectual, rather than local producers and thus no complicated sustainable resource management. That is what local producers don’t have and therefore it complicates the sustainable management of the resource.

  1. Sustainable Water Supplies in Uppsala, Sweden? (United States)

    Eriksson, Bert


    This is a description of a transdisciplinary three-day project with upper secondary school students around ecosystem services and sustainability. Uppsala (200 000 inhabitants) gets its municipal water from wells in the esker that dominates the landscape in and around the town. This esker was formed by glacial melt water around 11 000 BP, at the end of the latest glaciation and was lifted above sea level by post-glacial land rise from 6000 BP. To keep up the water table in the esker, water from river Fyris is pumped up and infiltrated in the esker. The river is also the recipient of wastewater downstream of the town, and the river runs out into Lake Mälaren that in its turn spills out into the Baltic Sea through Stockholm. The esker and river can thus be a central topic to work around, in Biology and Geography in upper secondary school, concerning recent and future water supplies, quaternary geology, limnology and landscape history. The fieldwork is carried out during three days in a period of three subsequent weeks. 1. One day is used to examine the water quality in the river above the town, organisms, pH, levels of nitrogen and phosphorous, conductivity and turbidity. Then the direction of the water is followed, first up to the infiltration dams on the esker, and then along the esker to the wells in the town. The formation of the esker and other traces in the landscape from the latest glaciation is also studied, as well as the historical use of the esker as a road and as a source of gravel and sand. The tap water that comes from the wells is finally tested in school in the same way as in the river. 2. The second day is used to follow the wastewater from households to the sewage plant, where the staff presents the plant. The water quality is tested in the same way as above in the outlet from the plant to the river. 3. The third day consists of a limnological excursion on the lake outside the mouth of the river where plankton and other organisms are studied, as

  2. Developing Sustainable Spacecraft Water Management Systems (United States)

    Thomas, Evan A.; Klaus, David M.


    It is well recognized that water handling systems used in a spacecraft are prone to failure caused by biofouling and mineral scaling, which can clog mechanical systems and degrade the performance of capillary-based technologies. Long duration spaceflight applications, such as extended stays at a Lunar Outpost or during a Mars transit mission, will increasingly benefit from hardware that is generally more robust and operationally sustainable overtime. This paper presents potential design and testing considerations for improving the reliability of water handling technologies for exploration spacecraft. Our application of interest is to devise a spacecraft wastewater management system wherein fouling can be accommodated by design attributes of the management hardware, rather than implementing some means of preventing its occurrence.

    Wang, Chengshuai; Xu, Lirong; Fu, Xin


    In this paper, the method of the water ecological footprint (WEF) was used to evaluate water resources carrying capacity and water resources sustainability of Tuhai River Basin in Shandong Province. The results show that: (1) The WEF had a downward trend in overall volatility in Tuhai River Basin from 2003 to 2011. Agricultural water occupies high proportion, which was a major contributor to the WEF, and about 86.9% of agricultural WEF was used for farmland irrigation; (2) The water resources carrying capacity had a downward trend in general, which was mostly affected by some natural factors in this basin such as hydrology and meteorology in Tuhai River Basin; (3) Based on analysis of water resources ecological deficit, it can be concluded that the water resources utilization mode was in an unhealthy pattern and it was necessary to improve the utilization efficiency of water resources in Tuhai River Basin; (4) In view of water resources utilization problems in the studied area, well irrigation should be greatly developed at the head of Yellow River Irrigation Area(YRIA), however, water from Yellow River should be utilized for irrigation as much as possible, combined with agricultural water-saving measures and controlled exploiting groundwater at the tail of YRIA. Therefore, the combined usage of surface water and ground water of YRIA is an important way to realize agricultural water saving and sustainable utilization of water resources in Tuhai River Basin.

  12. Self-Sustaining Thorium Boiling Water Reactors

    Directory of Open Access Journals (Sweden)

    Ehud Greenspan


    Full Text Available A thorium-fueled water-cooled reactor core design approach that features a radially uniform composition of fuel rods in stationary fuel assembly and is fuel-self-sustaining is described. This core design concept is similar to the Reduced moderation Boiling Water Reactor (RBWR proposed by Hitachi to fit within an ABWR pressure vessel, with the following exceptions: use of thorium instead of depleted uranium for the fertile fuel; elimination of the internal blanket; and elimination of absorbers from the axial reflectors, while increasing the length of the fissile zone. The preliminary analysis indicates that it is feasible to design such cores to be fuel-self-sustaining and to have a comfortably low peak linear heat generation rate when operating at the nominal ABWR power level of nearly 4000 MWth. However, the void reactivity feedback tends to be too negative, making it difficult to have sufficient shutdown reactivity margin at cold zero power condition. An addition of a small amount of plutonium from LWR used nuclear fuel was found effective in reducing the magnitude of the negative void reactivity effect and enables attaining adequate shutdown reactivity margin; it also flattens the axial power distribution. The resulting design concept offers an efficient incineration of the LWR generated plutonium in addition to effective utilization of thorium. Additional R&D is required in order to arrive at a reliable practical and safe design.

    The current economic paradigm, which is based on increasing human population, economic development, and standard of living, is no longer compatible with the biophysical limits of the finite Earth. Failure to recover from the economic crash of 2008 is not due just to inadequate fiscal and monetary policies. The continuing global crisis is also due to scarcity of critical resources. Our macroecological studies highlight the role in the economy of energy and natural resources: oil, gas, water, arable land, metals, rare earths, fertilizers, fisheries, and wood. As the modern industrial technological-informational economy expanded in recent decades, it grew by consuming the Earth's natural resources at unsustainable rates. Correlations between per capita GDP and per capita consumption of energy and other resources across nations and over time demonstrate how economic growth and development depend on "nature's capital". Decades-long trends of decreasing per capita consumption of multiple important commodities indicate that overexploitation has created an unsustainable bubble of population and economy.

  19. RESOLVE Projects: Lunar Water Resource Demonstration and Regolith Volatile Characterization (United States)


    To sustain affordable human and robotic space exploration, the ability to live off the land at the exploration site will be essential. NASA calls this ability in situ resource utilization (ISRU) and is focusing on finding ways to sustain missions first on the Moon and then on Mars. The ISRU project aims to develop capabilities to technology readiness level 6 for the Robotic Lunar Exploration Program and early human missions returning to the Moon. NASA is concentrating on three primary areas of ISRU: (1) excavating, handling, and moving lunar regolith, (2) extracting oxygen from lunar regolith, and (3) finding, characterizing, extracting, separating, and storing volatile lunar resources, especially in the permanently shadowed polar craters. To meet the challenges related to technology development for these three primary focus areas, the Regolith and Environment Science and Oxygen and Lunar Volatile Extraction (RESOLVE) project was initiated in February 2005, through funding by the Exploration Systems Mission Directorate. RESOLVE's objectives are to develop requirements and conceptual designs and to perform breadboard concept verification testing of each experiment module. The final goal is to deliver a flight prototype unit that has been tested in a relevant lunar polar environment. Here we report progress toward the third primary area creating ways to find, characterize, extract, separate, and store volatile lunar resources. The tasks include studying thermal, chemical, and electrical ways to collect such volatile resources as hydrogen, water, nitrogen, methane, and ammonia. We approached this effort through two subtasks: lunar water resource demonstration (LWRD) and regolith volatile characterization (RVC).

  20. Public participation in water resources management: Restructuring model of upstream Musi watershed (United States)

    Andriani, Yuli; Zagloel, T. Yuri M.; Koestoer, R. H.; Suparmoko, M.


    Water is the source of life needed by living things. Human as one of living most in needs of water. Because the population growth follows the geometrical progression, while the natural resource increases calculates the arithmetic. Humans besides needing water also need land for shelter and for their livelihood needs, such as gardening or rice farmers. If the water absorption area is reduced, water availability will decrease. Therefore it is necessary to conduct an in-depth study of water resources management involving the community. The purpose of this study is to analyze community participation in water resources management, so that its availability can still meet the needs of living and sustainable. The method that used the level of community participation according to Arstein theory. The results obtained that community participation is at the level of partnership and power delegation. This level of participation is at the level of participation that determines the sustainability of water resources for present and future generations.

    Full Text Available Climate change impacts on water resources – The most recent scientific assessment by the Intergovernmental Panel on Climate Change (IPCC [6] concludes that, since the late 19th century, anthropogenic induced emissions of greenhouse gases have contributed to an increase in global surface temperatures of about 0.3 to 0.6o C. Based on the IPCC’s scenario of future greenhouse gas emissions and aerosols a further increase of 2o C is expected by the year 2100. Plants, animals, natural and managed ecosystems, and human settlements are susceptible to variations in the storage, fluxes, and quality of water and sensitive to climate change. From urban and agricultural water supplies to flood management and aquatic ecosystem protection, global warming is affecting all aspects of water resource management. Rising temperatures, loss of snowpack, escalating size and frequency of flood events, and rising sea levels are just some of the impacts of climate change that have broad implications for the management of water resources. With robust scientific evidence showing that human-induced climate change is occurring, it is critical to understand how water quantity and quality might be affected. The purpose of this paper is to highlight the environmental risks caused by climate anomalies on water resources, to examine the negative impacts of a greenhouse warming on the supply and demand for water and the resulting socio-economic implications.

  4. Urban water metabolism indicators derived from a water mass balance - Bridging the gap between visions and performance assessment of urban water resource management. (United States)

    Renouf, M A; Serrao-Neumann, S; Kenway, S J; Morgan, E A; Low Choy, D


    Improving resource management in urban areas has been enshrined in visions for achieving sustainable urban areas, but to date it has been difficult to quantify performance indicators to help identify more sustainable outcomes, especially for water resources. In this work, we advance quantitative indicators for what we refer to as the 'metabolic' features of urban water management: those related to resource efficiency (for water and also water-related energy and nutrients), supply internalisation, urban hydrological performance, sustainable extraction, and recognition of the diverse functions of water. We derived indicators in consultation with stakeholders to bridge this gap between visions and performance indicators. This was done by first reviewing and categorising water-related resource management objectives for city-regions, and then deriving indicators that can gauge performance against them. The ability for these indicators to be quantified using data from an urban water mass balance was also examined. Indicators of water efficiency, supply internalisation, and hydrological performance (relative to a reference case) can be generated using existing urban water mass balance methods. In the future, indicators for water-related energy and nutrient efficiencies could be generated by overlaying the urban water balance with energy and nutrient data. Indicators of sustainable extraction and recognising diverse functions of water will require methods for defining sustainable extraction rates and a water functionality index.

  5. Using NASA Products of the Water Cycle for Improved Water Resources Management (United States)

    Toll, D. L.; Doorn, B.; Engman, E. T.; Lawford, R. G.


    NASA Water Resources works within the Earth sciences and GEO community to leverage investments of space-based observation and modeling results including components of the hydrologic cycle into water resources management decision support tools for the goal towards the sustainable use of water. These Earth science hydrologic related observations and modeling products provide a huge volume of valuable data in both near-real-time and extended back nearly 50 years. Observations of this type enable assessment of numerous water resources management issues including water scarcity, extreme events of drought and floods, and water quality. Examples of water cycle estimates make towards the contributions to the water management community include snow cover and snowpack, soil moisture, evapotranspiration, precipitation, streamflow and ground water. The availability of water is also contingent on the quality of water and hence water quality is an important part of NASA Water Resources. Water quality activities include both nonpoint source (agriculture land use, ecosystem disturbances, impervious surfaces, etc.) and direct remote sensing ( i.e., turbidity, algae, aquatic vegetation, temperature, etc.). . The NASA Water Resources Program organizes its projects under five functional themes: 1) stream-flow and flood forecasting; 2) water consumptive use and irrigation (includes evapotranspiration); 3) drought; 4) water quality; and 5) climate impacts on water resources. Currently NASA Water Resources is supporting 21 funded projects with 11 additional projects being concluded. To maximize the use of NASA water cycle measurements end to projects are supported with strong links with decision support systems. The NASA Water Resources Program works closely with other government agencies NOAA, USDA-FAS, USGS, AFWA, USAID, universities, and non-profit, international, and private sector organizations. International water cycle applications include: 1) Famine Early Warning System Network

  6. Assessing Groundwater Resources Sustainability Using Groundwater Footprint Concept (United States)

    Charchousi, Despoina; Spanoudaki, Katerina; Papadopoulou, Maria P.


    Over-pumping, water table depletion and climate change impacts require effective groundwater management. The Groundwater Footprint (GWF), introduced by Gleeson et al. in 2012 expresses the area required to sustain groundwater use and groundwater dependent ecosystem services. GWF represents a water balance between aquifer inflows and outflows, focusing on environmental flow requirements. Developing the water balance, precipitation recharge and additional recharge from irrigation are considered as inflows, whereas outflows are considered the groundwater abstraction from the aquifer of interest and the quantity of groundwater that is needed to sustain ecosystem services. The parameters required for GWF calculation can be estimated through in-situ measurements, observations and models outputs. The actual groundwater abstraction is often difficult to be estimated with a high accuracy. Environmental flow requirements can be calculated through different approaches; the most accurate of which are considered the ones that focus on hydro-ecological data analysis. As the GWF is a tool recently introduced in groundwater assessment and management, only a few studies have been reported in the literature to use it as groundwater monitoring and management tool. The present study emphasizes on a case study in Southern Europe, where awareness should be raised about rivers' environmental flow. GWF concept will be applied for the first time to a pilot area in Greece, where the flow of the perennial river that crosses the area of interest is dependent on baseflow. Recharge and abstraction of the pilot area are estimated based on historical data and previous reports and a groundwater flow model is developed using Visual Modflow so as to diminish the uncertainty of the input parameters through model calibration. The groundwater quantity that should be allocated on surface water body in order to sustain satisfactory biological conditions is estimated under the assumption that surface

  12. Irrigated agriculture and groundwater resources - towards an integrated vision and sustainable relationship. (United States)

    Foster, Stephen; Garduño, Héctor


    Globally, irrigated agriculture is the largest abstractor, and predominant consumer, of groundwater resources, with large groundwater-dependent agro-economies now having widely evolved especially in Asia. Such use is also causing resource depletion and degradation in more arid and drought-prone regions. In addition crop cultivation practices on irrigated land exert a major influence on groundwater recharge. The interrelationship is such that cross-sector action is required to agree more sustainable land and water management policies, and this paper presents an integrated vision of the challenges in this regard. It is recognised that 'institutional arrangements' are critical to the local implementation of management policies, although the focus here is limited to the conceptual understanding needed for formulation of an integrated policy and some practical interventions required to promote more sustainable groundwater irrigation.

  13. Water resources of Iberia Parish, Louisiana (United States)

    White, Vincent E.; Prakken, Lawrence B.


    IntroductionInformation concerning the availability, use, and quality of water in Iberia Parish, Louisiana, is critical for proper water-resource management. This fact sheet summarizes the availability, past and current use, use trends, and water quality from groundwater and surface-water sources in the parish for water managers, parish residents, and others to assist in stewardship of this vital resource. Previously published reports and data stored in the U.S. Geological Survey’s National Water Information System are the primary sources of the information presented here.In 2010, about 31.24 million gallons per day (Mgal/d) of water were withdrawn in Iberia Parish, Louisiana, including about 23.13 Mgal/d from groundwater sources and 8.11 Mgal/d from surface-water sources. Withdrawals for public supply and industrial use each accounted for about 32 percent of the total water withdrawn. Other water-use categories included rural domestic, livestock, rice irrigation, general irrigation, and aquaculture. Water-use data collected at 5-year intervals from 1960 to 2010 indicated that water withdrawals in Iberia Parish peaked at about 58.57 Mgal/d in 1975.

  14. Sustainability of uranium mining and milling: toward quantifying resources and eco-efficiency. (United States)

    Mudd, Gavin M; Diesendorf, Mark


    The mining of uranium has long been a controversial public issue, and a renewed debate has emerged on the potential for nuclear power to help mitigate against climate change. The central thesis of pro-nuclear advocates is the lower carbon intensity of nuclear energy compared to fossil fuels, although there remains very little detailed analysis of the true carbon costs of nuclear energy. In this paper, we compile and analyze a range of data on uranium mining and milling, including uranium resources as well as sustainability metrics such as energy and water consumption and carbon emissions with respect to uranium production-arguably the first time for modern projects. The extent of economically recoverable uranium resources is clearly linked to exploration, technology, and economics but also inextricably to environmental costs such as energy/water/chemicals consumption, greenhouse gas emissions, and social issues. Overall, the data clearly show the sensitivity of sustainability assessments to the ore grade of the uranium deposit being mined and that significant gaps remain in complete sustainability reporting and accounting. This paper is a case study of the energy, water, and carbon costs of uranium mining and milling within the context of the nuclear energy chain.

  15. World Water Resources Assessment for 2050 (United States)

    Oki, T.; Agata, Y.; Kanae, S.; Musiake, K.; Saruhashi, T.


    nticipated water scarcity in the first half of this century is one of the most concerned international issues to be assessed adequately. However, even though the issue has an international impact and world wide monitoring is critical, there are limited number of global estimates at present. In this study, annual water availability was derived from annual runoff estimated by land surface models using Total Runoff Integrating Pathways (TRIP) with 0.5 degree by 0.5 degree longitude/latitude resolution globally. Global distribution of water withdrawal for each sector in the same horizontal spatial resolution was estimated based on country-base statistics of municipal water use, industrial water use, and agricultural intake, using global geographical information system with global distributions of population and irrigated crop land area. The total population under water stress estimated for 1995 corresponded very well with former estimates, however, the number is highly depend on how to assume the ratio how much water from upstream of the region can be considered as ``available'' water resources within the region. It suggests the importance of regional studies evaluating the the water quality deterioration in the upper stream, the real consumption of water resources in the upper stream, and the accessibility to water. The last factor should be closely related to how many large scale water withdrawal schemes are implemented in the region. Further studies by an integrated approach to improve the accuracy of future projections on both the natural and social sides of the water resources should be promoted. About the future projection of the global water resources assessment, population growth, climatic change, and the increase of water consumption per capita are considered. Population growth scenario follows the UN projection in each country. Change in annual runoff was estimated based on the climatic simulation by a general circulation model by the Center of Climate System

    Full Text Available Al-Ain is the second largest city in the Emirate of Abu Dhabi and the third in the UAE. Currently, desalination plants are the only source of drinking water in the city with an average daily supply of 170 MIG. Recently, Abu Dhabi Urban Planning Council (UPC released Al-Ain 2030 Plan. Projects suggested in this plan, over and above the expected natural population growth, will certainly put additional stress on the water resources in the city. Therefore, Al-Ain city seems to be in urgent need for an integrated water resources management strategy towards achieving sustainable development. This strategy will contain three main components; namely, a Water Demand Forecasting Model (WDFM, a Water Budget Model (WBM, and a Water Resources Optimization Model (WROM. The main aim of this paper is to present the WBM that estimates all inflows and outflows to assess water resources sustainability in the city.

  17. Sustainable water management under future uncertainty with eco-engineering decision scaling (United States)

    Managing freshwater resources sustainably under future climatic and hydrological uncertainty poses novel challenges. Rehabilitation of ageing infrastructure and construction of new dams are widely viewed as solutions to diminish climate risk, but attaining the broad goal of freshwater sustainability will require expansion of the prevailing water resources management paradigm beyond narrow economic criteria to include socially valued ecosystem functions and services. We introduce a new decision framework, eco-engineering decision scaling (EEDS), that explicitly and quantitatively explores trade-offs in stakeholder-defined engineering and ecological performance metrics across a range of possible management actions under unknown future hydrological and climate states. We illustrate its potential application through a hypothetical case study of the Iowa River, USA. EEDS holds promise as a powerful framework for operationalizing freshwater sustainability under future hydrological uncertainty by fostering collaboration across historically conflicting perspectives of water resource engineering and river conservation ecology to design and operate water infrastructure for social and environmental benefits.

    X. Huang


    Full Text Available The Dujiangyan Water-Conservancy Project is a great water irrigation works in Chinese cultural history, which led the Min River water to the vast Chengdu Plain, and created fertile and pretty "land of abundance". Now Chengdu is facing increased water demand stress due mainly to rapid urbanization. This paper first analyses the available water resources of Chengdu based on historical hydrological data from 1964 to 2008. The results show that the average annual water resources were 8.9 billion m3 in 1986 and 7.9 billion m3 in 2008 under various environmental conditions. The future tendency of water demand in city development planning is predicted by the Policy Dialogue Model (PODIUM. Finally, the strategies for water resources exploitation accompanying the sustainable development pattern are studied. The result illustrates that rational and careful management are required to balance the gap between water supply and demand

  19. Water Intensity of Electricity from Geothermal Resources (United States)

    Mishra, G. S.; Glassley, W. E.


    BACKGROUND Electricity from geothermal resources could play a significant role in the United States over the next few decades; a 2006 study by MIT expects a capacity of 100GWe by 2050 as feasible; approximately 10% of total electricity generating capacity up from less than 1% today. However, there is limited research on the water requirements and impacts of generating electricity from geothermal resources - conventional as well as enhanced. To the best of our knowledge, there is no baseline exists for water requirements of geothermal electricity. Water is primarily required for cooling and dissipation of waste heat in the power plants, and to account for fluid losses during heat mining of enhanced geothermal resources. MODEL DESCRIPTION We have developed a model to assess and characterize water requirements of electricity from hydrothermal resources and enhanced geothermal resources (EGS). Our model also considers a host of factors that influence cooling water requirements ; these include the temperature and chemical composition of geothermal resource; installed power generation technology - flash, organic rankine cycle and the various configurations of these technologies; cooling technologies including air cooled condensers, wet recirculating cooling, and hybrid cooling; and finally water treatment and recycling installations. We expect to identify critical factors and technologies. Requirements for freshwater, degraded water and geothermal fluid are separately estimated. METHODOLOGY We have adopted a lifecycle analysis perspective that estimates water consumption at the goethermal field and power plant, and accounts for transmission and distribution losses before reaching the end user. Our model depends upon an extensive literature review to determine various relationships necessary to determine water usage - for example relationship between thermal efficiency and temperature of a binary power plant, or differences in efficiency between various ORC configurations

  20. Sustainable Water Systems for the City of Tomorrow—A Conceptual Framework

    Directory of Open Access Journals (Sweden)

    Xin (Cissy Ma


    Full Text Available Urban water systems are an example of complex, dynamic human–environment coupled systems which exhibit emergent behaviors that transcend individual scientific disciplines. While previous siloed approaches to water services (i.e., water resources, drinking water, wastewater, and stormwater have led to great improvements in public health protection, sustainable solutions for a growing global population facing increased resource constraints demand a paradigm shift based on holistic management to maximize the use and recovery of water, energy, nutrients, and materials. The objective of this review paper is to highlight the issues in traditional water systems including water demand and use, centralized configuration, sewer collection systems, characteristics of mixed wastewater, and to explore alternative solutions such as decentralized water systems, fit for purpose and water reuse, natural/green infrastructure, vacuum sewer collection systems, and nutrient/energy recovery. This review also emphasizes a system thinking approach for evaluating alternatives that should include sustainability indicators and metrics such as emergy to assess global system efficiency. An example paradigm shift design for urban water system is presented, not as the recommended solution for all environments, but to emphasize the framework of system-level analysis and the need to visualize water services as an organic whole. When water systems are designed to maximize the resources and optimum efficiency, they are more prevailing and sustainable than siloed management because a system is more than the sum of its parts.

  1. Improvements in crop water productivity increase water sustainability and food security—a global analysis (United States)

    Brauman, Kate A.; Siebert, Stefan; Foley, Jonathan A.


    Irrigation consumes more water than any other human activity, and thus the challenges of water sustainability and food security are closely linked. To evaluate how water resources are used for food production, we examined global patterns of water productivity—food produced (kcal) per unit of water (l) consumed. We document considerable variability in crop water productivity globally, not only across different climatic zones but also within climatic zones. The least water productive systems are disproportionate freshwater consumers. On precipitation-limited croplands, we found that ∼40% of water consumption goes to production of just 20% of food calories. Because in many cases crop water productivity is well below optimal levels, in many cases farmers have substantial opportunities to improve water productivity. To demonstrate the potential impact of management interventions, we calculated that raising crop water productivity in precipitation-limited regions to the 20th percentile of productivity would increase annual production on rainfed cropland by enough to provide food for an estimated 110 million people, and water consumption on irrigated cropland would be reduced enough to meet the annual domestic water demands of nearly 1.4 billion people.

  2. Application of natural resource valuation concepts for development of sustainable remediation plans for groundwater. (United States)

    Connor, John A; Paquette, Shawn; McHugh, Thomas; Gie, Elaine; Hemingway, Mark; Bianchi, Gino


    This paper explores the application of natural resource assessment and valuation procedures as a tool for developing groundwater remediation strategies that achieve the objectives for health and environmental protection, in balance with considerations of economic viability and conservation of natural resources. The natural resource assessment process, as applied under U.S. and international guidelines, entails characterization of groundwater contamination in terms of the pre-existing beneficial services of the impacted resource, the loss of these services caused by the contamination, and the measures and associated costs necessary to restore or replace the lost services. Under many regulatory programs, groundwater remediation objectives assume that the impacted groundwater may be used as a primary source of drinking water in the future, even if not presently in use. In combination with a regulatory preference for removal or treatment technologies, this assumed exposure, while protective of human health, can drive the remedy selection process toward remedies that may not be protective of the groundwater resource itself or of the other natural resources (energy, materials, chemicals, etc.) that may be consumed in the remediation effort. To achieve the same health and environmental protection goals under a sustainable remediation framework, natural resource assessment methods can be applied to restore the lost services and preserve the intact services of the groundwater so as to protect both current and future users of that resource. In this paper, we provide practical guidelines for use of natural resource assessment procedures in the remedy selection process and present a case study demonstrating the use of these protocols for development of sustainable remediation strategies.

  3. Establishing Vulnerability Map of Water Resources in Regional Water Supply System (United States)

    Liu, T. M.; Tung, C. P.; Li, M. H.


    In recent years, the threat of increasing frequency of extreme weather rise up human attention on climate change. To reduce the threat of water scarcity, it is important to know how climate change might affect regional water resources and where the hotspots, the vulnerability points, are. However, there is not much information to help government understanding how climate change will affect the water resources locally. To a regional water supply system, there might be some hotspots more vulnerable to climate due to the lack of water treatment plants or tape water pipe system. And also, there might be some hotspots more vulnerable due to high population and high industrial product value when they expose to the same threat of water scarcity. This study aims to evaluate the spatial vulnerability distribution of water resources and propose the adaptive plan for southern region of Taiwan. An integrated tool - TaiWAP (Taiwan Water Resources Assessment Program) for climate change vulnerability assessment on water resources, which includes 10 GCMs output of SRES A2, A1B, B2 scenarios, weather generator, GWLF model, and Analytic Hierarchy Process (AHP) tool is used for climate impact assessment. For the simulation of the complex water supply system, the system dynamics model- VENSIM which is connected with TaiWAP is adopted to simulate a water supply system and evaluate vulnerability of each unit in a water supply system. The vulnerable hotspots will be indicated in the system and the adaptive strategies will be applied to strengthen the local vulnerable area. The adaptive capacity will be enhanced to mitigate climate change impacts on water supply system locally to achieve sustainable water uses.

  4. NASA's Applied Sciences for Water Resources (United States)

    Doorn, Bradley; Toll, David; Engman, Ted


    The Earth Systems Division within NASA has the primary responsibility for the Earth Science Applied Science Program and the objective to accelerate the use of NASA science results in applications to help solve problems important to society and the economy. The primary goal of the Earth Science Applied Science Program is to improve future and current operational systems by infusing them with scientific knowledge of the Earth system gained through space-based observation, assimilation of new observations, and development and deployment of enabling technologies, systems, and capabilities. This paper discusses one of the major problems facing water resources managers, that of having timely and accurate data to drive their decision support tools. It then describes how NASA?s science and space based satellites may be used to overcome this problem. Opportunities for the water resources community to participate in NASA?s Water Resources Applications Program are described.

  6. Managing Water Sustainability: Virtual Water Flows and Economic Water Productivity Assessment of the Wine Trade between Italy and the Balkans

    Directory of Open Access Journals (Sweden)

    Pier Paolo Miglietta


    Full Text Available The management of natural resources in economic activities has become a fundamental issue when considering the perspective of sustainable development. It is necessary to rethink every process in order to reach efficiency from different points of view, not only environmentally but also economically. Water scarcity is growing because of economic and population growth, climate change, and the increasing water demand. Currently, agri-food represents the most water consumptive sector, and the increasing importance of international trade in this industry puts freshwater issues in a global context that should be analyzed and regulated by sustainable policies. This analysis is focused on virtual water flows and economic water productivity related to the wine trade, and aims to evaluate water loss/savings achieved through bilateral trade relations. The choice fell on Italy, the first wine producer in the world, and the Balkan countries. The latter are new markets for wine production/consumption, in which Italian wines are strongly positioned for different reasons. The results show that, from a national point of view and considering wine trade, Italy exports water in virtual form to the Balkan countries, more than it imports, so that in effect it partially uses its own water resources for the wine supply of the Balkans. The latter, on the other hand, being a net importer of wine, partially depends on Italian water resources and exerts less pressure on their own water basins in the supporting wine supply. We also observed that the wine trade between Italy and the Balkans implies global water savings.

    Full Text Available Nowadays, it is important to achieve and to sustain an organization’s competitive advantage in complex environments. This paper evaluates different concepts that have led to such benefits. The study sheds light on resource based view (RBV and its role to reach sustainable competitive advantage (SCA within banking industry of Iran. A valid research instrument was utilized to conduct a survey of 150 top- and middle-level managers from Mellat bank of Iran. With a response rate of 81.3 percent, 122 questionnaires were returned while a number of valid and usable questionnaires were 101. In order to determine validity of questionnaire, the content validity and Cronbach's alpha were used to determine the reliability of the questionnaire (RBV questionnaire 0.934, SCA questionnaire 0.843. The study utilized structural equation modelling, and a series of exploratory and confirmatory factor analyses and they tested the integrated model of MKM and SCA. Statistical support was found for the hypothesized relationships. Moreover it has been shown that RBV had the greatest effect on the market centered SCA, while it had the least influence on the financial centered. The findings offer valuable insights on the generalizability of MKM in a research setting. Structural equation modeling has been implemented and the study also used freedman test to rank the factors and the results show that communication was the most important factor (4.41, followed by process (4.03, knowledge implementation (2.79, decision making (2.54 and human resources (1.22 was the last important factor.

  8. Nonregenerative natural resources in a sustainable system of energy supply. (United States)

    Bradshaw, Alex M; Hamacher, Thomas


    Following the lead of the European Union in introducing binding measures to promote the use of regenerative energy forms, it is not unreasonable to assume that the global demand for combustible raw materials for energy generation will be reduced considerably in the second half of this century. This will not only have a favourable effect on the CO(2) concentration in the atmosphere, but will also help preserve fossil fuels-important as raw materials in the chemical industry-for future generations. Nevertheless, associated with the concomitant massive shift to regenerative energy forms, there will be a strong demand for other exhaustible raw materials, in particular metals, some of which are already regarded as scarce. After reviewing the debate on mineral depletion between "cornucopians" and "pessimists", we discuss the meaning of mineral "scarcity", particularly in the geochemical sense, and mineral "exhaustion". The expected drastic increase in demand for mineral resources caused by demographic and societal pressures, that is, due to the increase in in-use stock, is emphasised. Whilst not discussing the issue of "strong" versus "weak" sustainability in detail, we conclude that regenerative energy systems-like nearly all resource-consuming systems in our society-do not necessarily satisfy generally accepted sustainability criteria. In this regard, we discuss some current examples, namely, lithium and cobalt for batteries, rare earth-based permanent magnets for wind turbines, cadmium and tellurium for solar cells and copper for electrical power distribution.

  9. Sustainable Development Strategy for Russian Mineral Resources Extracting Economy (United States)

    Dotsenko, Elena; Ezdina, Natalya; Prilepskaya, Angelina; Pivnyk, Kirill


    The immaturity of strategic and conceptual documents in the sphere of sustainable development of the Russian economy had a negative impact on long-term strategic forecasting of its neo-industrialization. At the present stage, the problems of overcoming the mineral and raw material dependence, the negative structural shift of the Russian economy, the acceleration of the rates of economic growth, the reduction of technological gap from the developed countries become strategically in demand. The modern structure of the Russian economy, developed within the framework of the proposed market model, does not generate a sustainable type of development. It became obvious that in conditions of the market processes' entropy, without neo-industrial changes, the reconstruction of industry on a new convergence-technological basis and without increasing the share of high technology production the instability of macroeconomic system, the risks of environmental and economic security of Russia are growing. Therefore, today we need a transition from forming one industry development strategy to the national one that will take into account both the social and economic and environmental challenges facing Russia as a mineral resources extracting country.

  10. From economics to resources: Teaching environmental sustainability in Peru's public education (United States)

    Adriazola-Rodriguez, Ana

    This dissertation examines the teaching of environmental awareness in Peru's public educational system and how it needs to be consciously taught and improved in order to overcome contamination and pollution of resources and decrease poverty. This is a situation afflicting a significant percentage of Peruvians, who face difficulty in surviving and living well because the scarcity of clean air and water, unpolluted land, and affordable energy, which are basic environmental resources. The teaching of environmental awareness, as mandated by Educational Peruvian Laws and curriculum, should be redesigned to promote environmental ethical awareness and sustainability to guard Peru's natural and cultural resources, bounty and beauty before it is too late. In this way, education will promote a better level of life for the majority of Peruvians. Peruvian public education is presently in a state of emergency, as has been recognized by the former minister of education Javier Sota Nadal (2004-2006). Only 10% of students leaving high school understand what they read and only 4% do well in mathematics. A number of reasons contribute to this tragedy. Among them is principally the low quality of teaching and the inadequate budget available for public education. Peru's laws, echoing the Universal Declaration of Human Rights, and mandate good and free education and guarantee the right to live well. The reality is that none of these rights are properly given to the majority of poor Peruvians. This dissertation offers a course of action to teach and spread out not only environmental awareness, but also environmental ethics and sustainability from a personal perspective. This rounded concept, if applied, will form citizens able to guard, protect, and preserve natural and cultural resources. The needed environmental ethics and sustainability education will gradually guarantee, from early in life, a truthful way to love, care, protect and preserve the ecosystem. Also encompassed within

  12. Modeling resource basis for social and economic development strategies: Water resource case (United States)

    Kosolapova, Natalia A.; Matveeva, Ludmila G.; Nikitaeva, Anastasia Y.; Molapisi, Lesego


    The article substantiates that the effectiveness of implementing socio-economic development strategies is to a large extent determined by the adequate provision of basic resources. The key role of water resources in economic strategic development is empirically illustrated. The article demonstrates the practicability of strategic management of water resources based on the principle of a combination of river basin management approaches and the consideration of regional development strategies. The Game Theory technique was used to develop economic and mathematical tools for supporting decision-making in meeting the needs of regional consumers under water balance deficit conditions. The choice of methods was determined from two positions: the methods should allow for the possibility of multi-variant solutions for the selection of optimal options for the distribution of limited water resources between different consumers; the methods should be orientated on the maximum possible harmonization of multidirectional and multi-scale interests of the subjects in the water management system of the different regions (including the state) in order to achieve a balance. The approbation of developing a toolkit for the example of the regions located in the Don and Kuban river basins resulted in the appropriate selection of priority regions for the allocation of water resources in terms of strategic management as well as the determination of measures of ensuring the sustainable use of the river basins under consideration. The proposed tools can be used for coordinating decisions on the water supply of regional economic systems with actual and projected indicators of socio-economic development of the respective regions for a strategic perspective.

  13. Linking water resources to food security through virtual water (United States)

    Tamea, Stefania


    The largest use of global freshwater resources is related to food production. While each day we drink about 2 liters of water, we consume (eating) about 4000 liters of ''virtual water'', which represents the freshwater used to produce crop-based and livestock-based food. Considering human water consumption as a whole, most part originates from agriculture (85.8%), and only minor parts come from industry (9.6%) or households (4.6%). These numbers shed light on the great pressure of humanity on global freshwater resources and justify the increasing interest towards this form of environmental impact, usually known as ''water footprint''. Virtual water is a key variable in establishing the nexus between water and food. In fact, water resources used for agricultural production determine local food availability, and impact the international trade of agricultural goods. Trade, in turn, makes food commodities available to nations which are not otherwise self-sufficient, in terms of water resources or food, and it establishes an equilibrium between food demand and production at the global scale. Therefore, food security strongly relies on international food trade, but also on the use of distant and foreign water resources, which need to be acknowledged and investigated. Virtual water embedded in production and international trade follows the fate of food on the trade network, generating virtual flows of great magnitude (e.g., 2800 km3 in 2010) and defining local and global virtual water balances worldwide. The resulting water-food nexus is critical for the societal and economic development, and it has several implications ranging from population dynamics to the competing use of freshwater resources, from dietary guidelines to globalization of trade, from externalization of pollution to policy making and to socio-economic wealth. All these implications represent a great challenge for future research, not only in hydrology but in the many fields related to this

  14. Macroecology Meets Macroeconomics: Resource Scarcity and Global Sustainability (United States)

    Brown, James H.; Burger, Joseph R.; Burnside, William R.; Chang, Michael; Davidson, Ana D.; Fristoe, Trevor S.; Hamilton, Marcus J.; Hammond, Sean T.; Kodric-Brown, Astrid; Mercado-Silva, Norman; Nekola, Jeffrey C.; Okie, Jordan G.


    The current economic paradigm, which is based on increasing human population, economic development, and standard of living, is no longer compatible with the biophysical limits of the finite Earth. Failure to recover from the economic crash of 2008 is not due just to inadequate fiscal and monetary policies. The continuing global crisis is also due to scarcity of critical resources. Our macroecological studies highlight the role in the economy of energy and natural resources: oil, gas, water, arable land, metals, rare earths, fertilizers, fisheries, and wood. As the modern industrial technological-informational economy expanded in recent decades, it grew by consuming the Earth’s natural resources at unsustainable rates. Correlations between per capita GDP and per capita consumption of energy and other resources across nations and over time demonstrate how economic growth and development depend on “nature’s capital”. Decades-long trends of decreasing per capita consumption of multiple important commodities indicate that overexploitation has created an unsustainable bubble of population and economy. PMID:24882946

  15. China’s Land Resources Dilemma: Problems, Outcomes, and Options for Sustainable Land Restoration

    Directory of Open Access Journals (Sweden)

    Lulu Zhang


    Full Text Available Pressing issues such as water and food security, health, peace, and poverty are deeply linked to land degradation. We use China’s major land restoration programs as a case offering perspective on the existing problems in China’s major policies for improving degraded land and maintaining land resources in three dimensions. The shortcomings and outcomes in terms of biophysical consequences, socioeconomic benefits, and political goals are addressed, namely (i non-integrated land resources management creates new problems while solving existing problems, (ii non-participatory processes and “one-size-fits-all” measures compromise socioeconomic benefits, and (iii implementation outcomes conflict with policy targets for sustainable land management and development. Based on discussions for more sustainable land management, we conclude that China needs to create a new mode of ‘economy and environment’ in plans and actions of restoring degraded land resources. Establishing multifunctional land-use systems based on formulating and balancing multiple benefits/services across socio-ecological sectors can be an option to achieve such a mode. At the end, recommendations are given for research and implementation that are not only vital for China but also relevant for other regions since the challenges of afforestation and sustainable land development faced in China are not unique.

  17. Factors affecting sustainability of rural water schemes in Swaziland (United States)

    Peter, Graciana; Nkambule, Sizwe E.

    The Millennium Development Goal (MDG) target to reduce the proportion of people without sustainable access to safe drinking water by the year 2015 has been met as of 2010, but huge disparities exist. Some regions, particularly Sub-Saharan Africa are lagging behind it is also in this region where up to 30% of the rural schemes are not functional at any given time. There is need for more studies on factors affecting sustainability and necessary measures which when implemented will improve the sustainability of rural water schemes. The main objective of this study was to assess the main factors affecting the sustainability of rural water schemes in Swaziland using a Multi-Criteria Analysis Approach. The main factors considered were: financial, social, technical, environmental and institutional. The study was done in Lubombo region. Fifteen functional water schemes in 11 communities were studied. Data was collected using questionnaires, checklist and focused group discussion guide. A total of 174 heads of households were interviewed. Statistical Package for Social Sciences (SPSS) was used to analyse the data and to calculate sustainability scores for water schemes. SPSS was also used to classify sustainability scores according to sustainability categories: sustainable, partially sustainable and non-sustainable. The averages of the ratings for the different sub-factors studied and the results on the sustainability scores for the sustainable, partially sustainable and non-sustainable schemes were then computed and compared to establish the main factors influencing sustainability of the water schemes. The results indicated technical and social factors as most critical while financial and institutional, although important, played a lesser role. Factors which contributed to the sustainability of water schemes were: functionality; design flow; water fetching time; ability to meet additional demand; use by population; equity; participation in decision making on operation and

  20. Advancing Water Footprint Assessment Research: Challenges in Monitoring Progress towards Sustainable Development Goal 6

    Directory of Open Access Journals (Sweden)

    Arjen Y. Hoekstra


    Full Text Available This special issue is a collection of recent papers in the field of Water Footprint Assessment (WFA, an emerging area of research focused on the analysis of freshwater use, scarcity, and pollution in relation to consumption, production, and trade. As increasing freshwater scarcity forms a major risk to the global economy, sustainable management of water resources is a prerequisite to development. We introduce the papers in this special issue by relating them to Sustainable Development Goal (SDG number 6 of the United Nations, the goal on water. We will particularly articulate how each paper drives the understanding needed to achieve target 6.3 on water quality and pollution and target 6.4 on water-use efficiency and water scarcity. Regarding SDG 6, we conclude that it lacks any target on using green water more efficiently, and while addressing efficiency and sustainability of water use, it lacks a target on equitable sharing of water. The latter issue is receiving limited attention in research as well. By primarily focusing on water-use efficiency in farming and industries at the local level, to a lesser extent to using water sustainably at the level of total water systems (like drainage basins, aquifers, and largely ignoring issues around equitable water use, understanding of our water problems and proposed solutions will likely remain unbalanced.

  1. Sustainable Human Presence on the Moon using In Situ Resources (United States)

    McLemore, Carol A.; Fikes, John C.; McCarley, Kevin S.; Darby, Charles A.; Curreri, Peter A.; Kennedy, James P.; Good, James E.; Gilley, Scott D.


    New capabilities, technologies and infrastructure must be developed to enable a sustained human presence on the moon and beyond. The key to having this permanent presence is the utilization of in situ resources. To this end, NASA is investigating how in situ resources can be utilized to improve mission success by reducing up-mass, improving safety, reducing risk, and bringing down costs for the overall mission. To ensure that this capability is available when needed, technology development is required now. NASA/Marshall Space Flight Center (MSFC) is supporting this endeavor, along with other NASA centers, by exploring how lunar regolith can be mined for uses such as construction, life support, propulsion, power, and fabrication. Efforts at MSFC include development of lunar regolith simulant for hardware testing and development, extraction of oxygen and other materials from the lunar regolith, production of parts and tools on the moon from local materials or from provisioned feedstocks, and capabilities to show that produced parts are "ready for use". This paper discusses the lunar regolith, how the regolith is being replicated in the development of simulants and possible uses of the regolith.

  3. Water Resources Impacts on Tribal Irrigation Projects (United States)

    Minihane, M.


    The Bureau of Indian Affairs (BIA) Branch of Irrigation and Power provides oversight and technical support to select irrigation projects and systems on tribal lands. The BIA provides operations and maintenance support for 16 irrigation systems. To make the best use of limited resources, the BIA must incorporate climate change impacts on hydrology and water management for these irrigation systems in the coming decades. The 16 irrigation projects discussed here are divided into three climatological regions: the Pacific Northwest Region, the Greater Rocky Mountain Region, and the Western, Southwest, & Navajo Region. Significant climate projections that impact irrigation systems in one or more of these regions include increased temperatures and evaporative demand, earlier snowmelt and runoff, an increase in floods, an increase in heavy precipitation events, an increase in the frequency and intensity of droughts, and declining water supplies. Some irrigation projects are particularly vulnerable to these climate impacts because they are in already water-stressed areas or areas in which water resources are over-allocated. Other irrigation projects will have to adjust their storage and water management strategies to accommodate changes in the timing of streamflow. Overall, though, the BIA will be better able to assist tribal nations by incorporating expected climate impacts into their water resources management practices.

  4. Water resources transfers through southern African food trade: water efficiency and climate signals (United States)

    Dalin, Carole; Conway, Declan


    Temporal and spatial variability of precipitation in southern Africa is particularly high. The associated drought and flood risks, combined with a largely rain-fed agriculture, pose a challenge for water and food security in the region. As regional collaboration strengthens through the Southern Africa Development Community and trade with other regions increases, it is thus important to understand both how climate variability affects agricultural productivity and how food trade (regional and extra-regional) can contribute to the region's capacity to deal with climate-related shocks. We combine global hydrological model simulations with international food trade data to quantify the water resources embedded in international food trade in southern Africa and with the rest of the world, from 1986-2011. We analyze the impacts of socio-economic changes and climatic variability on agricultural trade and embedded water resources during this period. We find that regional food trade is efficient in terms of water use but may be unsustainable because water-productive exporters, like South Africa, rely on increasingly stressed water resources. The role of imports from the rest of the world in the region's food supply is important, in particular during severe droughts. This reflects how trade can efficiently redistribute water resources across continents in response to a sudden gap in food production. In a context of regional and global integration, our results highlight opportunities for improved water-efficiency and sustainability of the region's food supply via trade.

  5. Efficient Use of Water Resources in the Steel Industry

    Directory of Open Access Journals (Sweden)

    Valentina Colla


    Full Text Available In the steel sector water management aims at improving the sustainability of the production cycle, resulting in resource efficiency benefits and in reduced water demand and costs. To be reused, water needs to be cooled and desalinized to avoid salt concentration in water circulation systems. The presented work includes two case studies carried out in an integrated steelmaking plant, respectively, to evaluate the possible implementation of ultrafiltration and reverse osmosis to reduce salt concentration in water streams and to investigate, through modelling and simulation, a process integration solution to improve water efficiency. Results showed that most salts are removed by reverse osmosis and that its coupling with ultrafiltration allows obtaining very high quality water; reuse of desalinated wastewater resulted in being more suitable and economically viable than its discharge. Moreover, modelling and simulation showed that the considered blowdown could be reused without significant changes in the receiving water network area. The industrial implementation of water recovery solutions can lead to a decrease of fresh water consumption, effluent discharge, and to improvement of product quality and equipment service life. The considered desalination technologies are transferable and easily implementable, and modelling and simulation are very useful in order to evaluate process modifications before real implementation.

  6. Water resource conflicts in the Middle East. (United States)

    Drake, C


    This article discusses the causes and sources of water resource conflict in the 3 major international river basins of the Middle East: the Tigris-Euphrates, the Nile, and the Jordan-Yarmuk. The physical geography of the Middle East is arid due to descending air, northeast trade winds, the southerly location, and high evaporation rates. Only Turkey, Iran, and Lebanon have adequate rainfall for population needs. Their mountainous geography and more northerly locations intercept rain and snow bearing westerly winds in winter. Parts of every other country are vulnerable to water shortages. Rainfall is irregular. Water resource conflicts are due to growing populations, economic development, rising standards of living, technological developments, political fragmentation, and poor water management. Immigration to the Jordan-Yarmuk watershed has added to population growth in this location. Over 50% of the population in the Middle East lives in urban areas where populations consume 10-12 times more water than those in rural areas. Water is wasted in irrigation schemes and huge dams with reservoirs where increased evaporation occurs. Technology results in greater water extraction of shallow groundwater and pollution of rivers and aquifers. British colonial government control led to reduced friction in most of the Nile basin. Now all ethnic groups have become more competitive and nationalistic. The Cold War restrained some of the conflict. Israel obtains 40% of its water from aquifers beneath the West Bank and Gaza. Geopolitical factors determine the mutual goodwill in managing international water. The 3 major water basins in the Middle East pose the greatest risk of water disputes. Possible solutions include conservation, better management, prioritizing uses, technological solutions, increased cooperation among co-riparians, developing better and enforceable international water laws, and reducing population growth rates.

  11. Policy Sciences in Water Resources Research (United States)

    Cummings, Ronald G.


    As the newly appointed Policy Sciences Editor for this journal, I would like to take this opportunity to introduce myself to WRR's readership as well as to offer a few comments concerning my views of policy sciences in water resources research. I am an economist working in the area of natural resources and environmental management. As such, I've spent a good part of my research career working with noneconomists. During 1969-1972, I worked in Mexico with hydrologists and engineers from Mexico's Water Resources Ministry in efforts to assess management/investment programs for reservoir systems and systems for interbasin water transfers. Between 1972 and 1975, while serving as Chairman of the Department of Resource Economics at the University of Rhode Island, my research involved collaborative efforts with biologists and soil scientists in studies concerning the conjunctive management of reservoirs for agricultural and lagoon systems and the control of salinity levels in soils and aquifers. Since 1975, at which time I joined the faculty at the University of New Mexico, I have worked with engineers at the Los Alamos National Laboratory in developing operation/management models for hot, dry rock geothermal systems and, more recently, with legal scholars and hydrologists in analyses of water rights issues. Thus I am comfortable with and appreciative of research conducted by my colleagues in systems engineering, operations research, and hydrology, as well as those in economics, law, and other social sciences.

    Due to the adaption, dynamic and multi-objective characteristics of complex water resources system, it is a considerable challenge to manage water resources in an efficient, equitable and sustainable way. An integrated optimal allocation model is proposed for complex adaptive system of water resources management. The model consists of three modules: (1) an agent-based module for revealing evolution mechanism of complex adaptive system using agent-based, system dynamic and non-dominated sorting genetic algorithm II methods, (2) an optimal module for deriving decision set of water resources allocation using multi-objective genetic algorithm, and (3) a multi-objective evaluation module for evaluating the efficiency of the optimal module and selecting the optimal water resources allocation scheme using project pursuit method. This study has provided a theoretical framework for adaptive allocation, dynamic allocation and multi-objective optimization for a complex adaptive system of water resources management.

  18. Issues of Sustainability of Coastal Groundwater Resources: Benin, West Africa

    Directory of Open Access Journals (Sweden)

    Andrew D. Mullen


    Full Text Available The largest city in Benin, West Africa (Cotonou, is reliant upon groundwater for its public water supply. This groundwater is derived from the Godomey well field which is located approximately 5 Km north of the coast of the Atlantic Ocean and in close proximity to Lake Nokoue—a shallow lake containing water with elevated concentration of chloride and other elements. Historical data indicate increased chloride concentration in a number of wells nearest to the lake, with unknown contribution from groundwater encroachment from the coastal area. Hence, there is substantial interest in better characterizing this groundwater system for the purpose of determining appropriate management practices and degree of sustainability. Among the efforts attempted to date are a series of numerical models ranging from assessment of flow to a recent effort to include density-dependent transport from the lake. In addition, substantial field characterization has been pursued including assessment of shallow water chemistry along the region of the coastal lagoon and border of the lake, characterization of hydraulic response to pumpage in the aquifer system, estimation of the distribution of electrical resistivity with depth along the coastal lagoons, and installation of multi-level piezometers at seven locations in the lake. When integrated across methods, these numerical and field results indicate that the lake remains a primary concern in terms of a source of salinity in the aquifer. Further, the coastal region appears to be more complex than previously suggested and may represent a future source of salt-water encroachment as suggested by current presence of saline waters at relatively shallow depths along the coast. Finally, hydraulic testing suggests that both natural and pumping-based fluctuations in water levels are present in this system. Substantial additional characterization and modeling efforts may provide a significantly greater understanding of the

    The design of urban systems that allow the introduction of techniques for the recycling and drainage of rainwater represents a new aspect for the development of urban planning with sustainability criteria, since its main objectives include: the optimisation of the use of water as a resource in cities, the minimisation of the impacts on the natural cycle of water, and the protection of the ecosystem upon which it depends. Our proposal is based on the so-called water-sensitive ur...

  20. Sustainable water demand management in the face of rapid urbanization and ground water depletion for social–ecological resilience building

    Directory of Open Access Journals (Sweden)

    Md. Arfanuzzaman


    Full Text Available Necessity of Sustainable water demand management (SWDM is immensely higher in the rapidly urbanized mega cities of the world where groundwater depletion and water deficit are taking place perilously. This paper focuses on the present condition of water demand, supply, system loss, pricing strategy, groundwater level, and per capita water consumption of Dhaka city, Bangladesh. The study founds population growth has a large influence on water demand to rise and demand of water is not responsive to the existing pricing rule adopted by DWASA. It emerges that, water demand is increasing at 4% rate an average in the Dhaka city since 1990 and groundwater table goes more than 70 m down in central capital due to extensive withdrawal of water. The study suggests an integrated SWDM approach, which incorporates optimum pricing, ground and surface water regulation, water conservation, sustainable water consumption and less water foot print to ease groundwater depletion. In order to attain sustainability in water demand management (WDM the study recommends certain criteria under economic, social and environmental segment to administer the increasing water demand of growing population and conserve the fresh water resources of the world’s mega cities for social–ecological resilience building.

  1. Entropy, recycling and macroeconomics of water resources (United States)

    Karakatsanis, Georgios; Mamassis, Nikos; Koutsoyiannis, Demetris


    We propose a macroeconomic model for water quantity and quality supply multipliers derived by water recycling (Karakatsanis et al. 2013). Macroeconomic models that incorporate natural resource conservation have become increasingly important (European Commission et al. 2012). In addition, as an estimated 80% of globally used freshwater is not reused (United Nations 2012), under increasing population trends, water recycling becomes a solution of high priority. Recycling of water resources creates two major conservation effects: (1) conservation of water in reservoirs and aquifers and (2) conservation of ecosystem carrying capacity due to wastewater flux reduction. Statistical distribution properties of the recycling efficiencies -on both water quantity and quality- for each sector are of vital economic importance. Uncertainty and complexity of water reuse in sectors are statistically quantified by entropy. High entropy of recycling efficiency values signifies greater efficiency dispersion; which -in turn- may indicate the need for additional infrastructure for the statistical distribution's both shifting and concentration towards higher efficiencies that lead to higher supply multipliers.

  2. Geospatial Data Standards for Indian Water Resources Systems (United States)

    Goyal, A.; Tyagi, H.; Gosain, A. K.; Khosa, R.


    Sustainable management of water resources is fundamental to the socio-economic development of any nation. There is an increasing degree of dependency on digital geographical data for monitoring, planning, managing and preserving the water resources and environmental quality. But the rising sophistication associated with the sharing of geospatial data among organizations or users, demands development of data standards for seamless information exchange among collaborators. Therefore, due to the realization that these datasets are vital for efficient use of Geographical Information Systems, there is a growing emphasis on data standards for modeling, encoding and communicating spatial data. Real world hydrologic interactions represented in a digital framework requires geospatial standards that may vary in contexts like: governance, resource inventory, cultural diversity, identifiers, role and scale. Though the prevalent standards for the hydrology data facilitate a particular need in a particular context but they lack a holistic approach. However, several worldwide initiatives such as Consortium for the Advancement of Hydrologic Sciences Inc. (USA), Infrastructure for Spatial Information in the European Community (Europe), Australian Water Resources Information System, etc., endeavour to address this issue of hydrology specific spatial data standards in a wholesome manner. But unfortunately there is no such provision for hydrology data exchange within the Indian community. Moreover, these standards somehow fail in providing powerful communication of the spatial hydrologic data. This study thus investigates the shortcomings of the existing industry standards for the hydrologic data models and then demonstrates a set of requirements for effective exchange of the hydrologic information in the Indian scenario.

  3. Frontier In-Situ Resource Utilization for Enabling Sustained Human Presence on Mars (United States)

    Moses, Robert W.; Bushnell, Dennis M.


    The currently known resources on Mars are massive, including extensive quantities of water and carbon dioxide and therefore carbon, hydrogen and oxygen for life support, fuels and plastics and much else. The regolith is replete with all manner of minerals. In Situ Resource Utilization (ISRU) applicable frontier technologies include robotics, machine intelligence, nanotechnology, synthetic biology, 3-D printing/additive manufacturing and autonomy. These technologies combined with the vast natural resources should enable serious, pre- and post-human arrival ISRU to greatly increase reliability and safety and reduce cost for human colonization of Mars. Various system-level transportation concepts employing Mars produced fuel would enable Mars resources to evolve into a primary center of trade for the inner solar system for eventually nearly everything required for space faring and colonization. Mars resources and their exploitation via extensive ISRU are the key to a viable, safe and affordable, human presence beyond Earth. The purpose of this paper is four-fold: 1) to highlight the latest discoveries of water, minerals, and other materials on Mars that reshape our thinking about the value and capabilities of Mars ISRU; 2) to summarize the previous literature on Mars ISRU processes, equipment, and approaches; 3) to point to frontier ISRU technologies and approaches that can lead to safe and affordable human missions to Mars; and 4) to suggest an implementation strategy whereby the ISRU elements are phased into the mission campaign over time to enable a sustainable and increasing human presence on Mars.

  4. Dynamic Programming Applications in Water Resources (United States)

    Yakowitz, Sidney


    The central intention of this survey is to review dynamic programming models for water resource problems and to examine computational techniques which have been used to obtain solutions to these problems. Problem areas surveyed here include aqueduct design, irrigation system control, project development, water quality maintenance, and reservoir operations analysis. Computational considerations impose severe limitation on the scale of dynamic programming problems which can be solved. Inventive numerical techniques for implementing dynamic programming have been applied to water resource problems. Discrete dynamic programming, differential dynamic programming, state incremental dynamic programming, and Howard's policy iteration method are among the techniques reviewed. Attempts have been made to delineate the successful applications, and speculative ideas are offered toward attacking problems which have not been solved satisfactorily.

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

  6. Water resources review: Wheeler Reservoir, 1990

    Energy Technology Data Exchange (ETDEWEB)

    Wallus, R.; Cox, J.P.


    Protection and enhancement of water quality is essential for attaining the full complement of beneficial uses of TVA reservoirs. The responsibility for improving and protecting TVA reservoir water quality is shared by various federal, state, and local agencies, as well as the thousands of corporations and property owners whose individual decisions affect water quality. TVA's role in this shared responsibility includes collecting and evaluating water resources data, disseminating water resources information, and acting as a catalyst to bring together agencies and individuals that have a responsibility or vested interest in correcting problems that have been identified. This report is one in a series of status reports that will be prepared for each of TVA's reservoirs. The purpose of this status report is to provide an up-to-date overview of the characteristics and conditions of Wheeler Reservoir, including: reservoir purposes and operation; physical characteristics of the reservoir and the watershed; water quality conditions: aquatic biological conditions: designated, actual, and potential uses of the reservoir and impairments of those uses; ongoing or planned reservoir management activities. Information and data presented here are form the most recent reports, publications, and original data available. 21 refs., 8 figs., 29 tabs.

  7. Law, Water and Sustainable Development: Framework of Nigerian Law - Country Legislation

    Directory of Open Access Journals (Sweden)

    Olawale Ajai


    Full Text Available The central issues of economic development and environmental protection in the current social, political and economic environment relate to water – an overlooked or less glamorous natural resource. For example, topical and sometimes controversial issues such as crude oil and minerals extraction, pollution control, biodiversity protection, energy and power, resource control, revenue allocation and political participation, etc., relate directly or indirectly to water resources management. This paper seeks to identify and present in a schematic and conceptual manner and to highlight the usefulness of folklore for sustainable development and evaluate the usefulness of recruiting traditional institutions into the institutional framework for modern sustainable water resources management in Nigeria It also discusses the emergent law on water resources as well as the issues concerning the domestic and international riparian law, in particular the River Niger and Lake Chad basins and explores how folklore, comparative law and international law may be adopted and adapted to aid the development and application of water law, and by direct implication sustainable development in Nigeria.

  8. The Water Resources Board: England and Wales’ Venture into National Water Resources Planning, 1964-1973

    Directory of Open Access Journals (Sweden)

    Christine S. McCulloch


    Full Text Available An era of technocratic national planning of water resources is examined against the views of a leading liberal economist and critics, both contemporary and retrospective. Post Second World War Labour Governments in Britain failed to nationalise either land or water. As late as 1965, the idea of public ownership of all water supplies appeared in the Labour Party manifesto and a short-lived Ministry of Land and Natural Resources, 1964-1966, had amongst its duties the development of plans for reorganising the water supply industry under full public ownership. However, instead of pursuing such a politically dangerous takeover of the industry, in July 1964, a Water Resources Board (WRB, a special interest group dominated by engineers, was set up to advise on the development of water resources. In its first Annual Report (1965 WRB claimed its role as "the master planner of the water resources of England and Wales". The WRB had a great deal of influence and justified its national planning role by promoting large-scale supply schemes such as interbasin transfers of water, large reservoirs and regulated rivers. Feasibility studies were even carried out for building innovative, large storage reservoirs in tidal estuaries. Less progress was made on demand reduction. Yet the seeds of WRB’s demise were contained in its restricted terms of reference. The lack of any remit over water quality was a fatal handicap. Quantity and quality needed to be considered together. Privatisation of the water industry in 1989 led to a shift from national strategic planning by engineers to attempts to strengthen economic instruments to fit supply more closely to demand. Engineers have now been usurped as leaders in water resources management by economists and accountants. Yet climate change may demand a return to national strategic planning of engineered water supply, with greater democratic input.

    Fertile soils are a fundamental resource for the production of biomass and provision of food and energy. A growing world population and latest climate targets lead to an increasing demand for bio-based products which require preserving and - ideally - improving the long-term productivity of soils as a bio-economic resource. At the same time, other soil functions and ecosystem services need to be maintained: filter for clean water, carbon sequestration, provision and recycling of nutrients, and habitat for biological activity. All these soil functions result from the interaction of a multitude of physical, chemical and biological processes which are insufficiently understood. In addition, we lack understanding about the interplay between the socio-economic system and the soil system and how soil functions benefit human wellbeing, including SDGs. However, a solid and integrated assessment of soil quality requires the consideration of the ensemble of soil functions and its relation to soil management. To make soil management sustainable, we need to establish a scientific knowledge base of complex soil system processes that allows for developing models and tools to quantitatively predict the impact of a multitude of management measures on soil functions. This will finally allow for the provision of options for a site-specific, sustainable soil management. To face this challenge, the German Federal Ministry of Education and Research (BMBF) recently launched the funding program "Soil as a Sustainable Resource for the Bioeconomy - BonaRes". In a joint effort, ten collaborative projects and the coordinating BonaRes Centre are engaged to close existing knowledge gaps for a profound and systemic assessment and understanding of soil functions and their sensitivity to soil management. In BonaRes, the complete process chain of sustainable soil use in the context of a sustainable bio-economy is being addressed: from understanding of soil processes using state-of the art and

    Energy Technology Data Exchange (ETDEWEB)

    McCarthy, Kathryn A. [Idaho National Lab. (INL), Idaho Falls, ID (United States)


    Welcome to the 2014 Light Water Reactor Sustainability (LWRS) Program Accomplishments Report, covering research and development highlights from 2014. The LWRS Program is a U.S. Department of Energy research and development program to inform and support the long-term operation of our nation’s commercial nuclear power plants. The research uses the unique facilities and capabilities at the Department of Energy national laboratories in collaboration with industry, academia, and international partners. Extending the operating lifetimes of current plants is essential to supporting our nation’s base load energy infrastructure, as well as reaching the Administration’s goal of reducing greenhouse gas emissions to 80% below 1990 levels by the year 2050. The purpose of the LWRS Program is to provide technical results for plant owners to make informed decisions on long-term operation and subsequent license renewal, reducing the uncertainty, and therefore the risk, associated with those decisions. In January 2013, 104 nuclear power plants operated in 31 states. However, since then, five plants have been shut down (several due to economic reasons), with additional shutdowns under consideration. The LWRS Program aims to minimize the number of plants that are shut down, with R&D that supports long-term operation both directly (via data that is needed for subsequent license renewal), as well indirectly (with models and technology that provide economic benefits). The LWRS Program continues to work closely with the Electric Power Research Institute (EPRI) to ensure that the body of information needed to support SLR decisions and actions is available in a timely manner. This report covers selected highlights from the three research pathways in the LWRS Program: Materials Aging and Degradation, Risk-Informed Safety Margin Characterization, and Advanced Instrumentation, Information, and Control Systems Technologies, as well as a look-ahead at planned activities for 2015.

  2. Assessing The Ecosystem Service Freshwater Production From An Integrated Water Resources Management Perspective. Case Study: The Tormes Water Resources System (Spain) (United States)

    Momblanch, Andrea; Paredes-Arquiola, Javier; Andreu, Joaquín; Solera, Abel


    The Ecosystem Services are defined as the conditions and processes through which natural ecosystems, and the species that make them up, sustain and fulfil human life. A strongly related concept is the Integrated Water Resources Management. It is a process which promotes the coordinated development and management of water, land and related resources in order to maximise the resultant economic and social welfare in an equitable manner without compromising the sustainability of vital ecosystems. From these definitions, it is clear that in order to cover so many water management and ecosystems related aspects the use of integrative models is increasingly necessary. In this study, we propose to link a hydrologic model and a water allocation model in order to assess the Freshwater Production as an Ecosystem Service in anthropised river basins. First, the hydrological model allows determining the volume of water generated by each sub-catchment; that is, the biophysical quantification of the service. This result shows the relevance of each sub-catchment as a source of freshwater and how this could change if the land uses are modified. On the other hand, the water management model allocates the available water resources among the different water uses. Then, it is possible to provide an economic value to the water resources through the use of demand curves, or other economic concepts. With this second model, we are able to obtain the economical quantification of the Ecosystem Service. Besides, the influence of water management and infrastructures on the service provision can be analysed. The methodology is applied to the Tormes Water Resources System, in Spain. The software used are EVALHID and SIMGES, for hydrological and management aspects, respectively. Both models are included in the Decision Support System Shell AQUATOOL for water resources planning and management. A scenario approach is presented to illustrate the potential of the methodology, including the current

  4. Agricultural Impacts on Water Resources: Recommendations for Successful Applied Research (United States)

    Harmel, D.


    We, as water resource professionals, are faced with a truly monumental challenge - that is feeding the world's growing population and ensuring it has an adequate supply of clean water. As researchers and educators it is good for us to regularly remember that our research and outreach efforts are critical to people around the world, many of whom are desperate for solutions to water quality and supply problems and their impacts on food supply, land management, and ecosystem protection. In this presentation, recommendations for successful applied research on agricultural impacts on water resources will be provided. The benefits of building multidisciplinary teams will be illustrated with examples related to the development and world-wide application of the ALMANAC, SWAT, and EPIC/APEX models. The value of non-traditional partnerships will be shown by the Soil Health Partnership, a coalition of agricultural producers, chemical and seed companies, and environmental advocacy groups. The results of empowering decision-makers with useful data will be illustrated with examples related to bacteria source and transport data and the MANAGE database, which contains runoff nitrogen and phosphorus data for cultivated, pasture, and forest land uses. The benefits of focusing on sustainable solutions will be shown through examples of soil testing, fertilizers application, on-farm profit analysis, and soil health assessment. And the value of welcoming criticism will be illustrated by the development of a framework to estimate and publish uncertainty in measured discharge and water quality data. The good news for researchers is that the agricultural industry is faced with profitability concerns and the need to wisely utilize soil and water resources, and simultaneously state and federal agencies crave sound-science to improve decision making, policy, and regulation. Thus, the audience for and beneficiaries of agricultural research are ready and hungry for applied research results.

    In order to assess the sustainable use level of fisheries resources, Zhoushan Fishing Ground was selected as a demonstration. Based on 24 indicators related to the resource-environment subsystem and economic subsystem, principal component analysis was employed to analyze the indicator system in each subsystem, and grey relative relationship analysis was computed as a indicator to evaluate the sustainable use level of fisheries resources. The results indicated that the sustainable use of fisheries resources was at a lower level before 1962, and gradually rose to the top in 1974. It has sharply declined since 1978, and dropped to almost the lowest level in 1983, being 51.72% of 1974.

    Full Text Available The Tarim Basin in Xinjiang province in northwest China is characterized by a hyper arid climate. Climate change and a strong increase in agricultural land use are major challenges for sustainable water management. The largest competition for water resources exists between irrigated fields and natural riparian vegetation, which is dependent on seasonal flooding of the Tarim River. In addition to numerous water management measures implemented by the Chinese government, the Sino-German project SuMaRiO (Sustainable Management of River Oases along the Tarim River provided a decision support system based on ecosystem services for the Chinese stakeholders. This tool will help to implement sustainable land and water management measures in the next 5-year plan.

  8. Water resources of Sweetwater County, Wyoming (United States)

    Mason, Jon P.; Miller, Kirk A.


    Sweetwater County is located in the southwestern part of Wyoming and is the largest county in the State. A study to quantify the availability and describe the chemical quality of surface-water and ground-water resources in Sweetwater County was conducted by the U.S. Geological Survey in cooperation with the Wyoming State Engineers Office. Most of the county has an arid climate. For this reason a large amount of the flow in perennial streams within the county is derived from outside the county. Likewise, much of the ground-water recharge to aquifers within the county is from flows into the county, and occurs slowly. Surface-water data were not collected as part of the study. Evaluations of streamflow and stream-water quality were limited to analyses of historical data and descriptions of previous investigations. Forty-six new ground-water-quality samples were collected as part of the study and the results from an additional 782 historical ground-water-quality samples were reviewed. Available hydrogeologic characteristics for various aquifers throughout the county also are described. Flow characteristics of streams in Sweetwater County vary substantially depending on regional and local basin characteristics and anthropogenic factors. Because precipitation amounts in the county are small, most streams in the county are ephemeral, flowing only as a result of regional or local rainfall or snowmelt runoff. Flows in perennial streams in the county generally are a result of snowmelt runoff in the mountainous headwater areas to the north, west, and south of the county. Flow characteristics of most perennial streams are altered substantially by diversions and regulation. Water-quality characteristics of selected streams in and near Sweetwater County during water years 1974 through 1983 were variable. Concentrations of dissolved constituents, suspended sediment, and bacteria generally were smallest at sites on the Green River because of resistant geologic units, increased

  9. Evaluation and Countermeasures on sustainable development of nickel resources in China (United States)

    Lin, Zhifeng


    Nickel is an important strategic resource in China. With the gradual reduction of nickel re-sources and the increasing competition of the global mineral resources market, the safety of nickel resources in China has been seriously threatened. Therefore, it is very important to evaluate the sustainable develop-ment of nickel resources in China and put forward the corresponding countermeasures. In this paper, the concept and research situation of sustainable development are analyzed. Based on the specific development of nickel resources in China, this paper uses AHP to evaluate the safety of nickel resources in china. Finally, it puts forward the concrete measures to implement the sustainable development strategy of nickel resources in China.

  10. Integrated water resources management using engineering measures

    Directory of Open Access Journals (Sweden)

    Y. Huang


    Full Text Available The management process of Integrated Water Resources Management (IWRM consists of aspects of policies/strategies, measures (engineering measures and non-engineering measures and organizational management structures, etc., among which engineering measures such as reservoirs, dikes, canals, etc., play the backbone that enables IWRM through redistribution and reallocation of water in time and space. Engineering measures are usually adopted for different objectives of water utilization and water disaster prevention, such as flood control and drought relief. The paper discusses the planning and implementation of engineering measures in IWRM of the Changjiang River, China. Planning and implementation practices of engineering measures for flood control and water utilization, etc., are presented. Operation practices of the Three Gorges Reservoir, particularly the development and application of regulation rules for flood management, power generation, water supply, ecosystem needs and sediment issues (e.g. erosion and siltation, are also presented. The experience obtained in the implementation of engineering measures in Changjiang River show that engineering measures are vital for IWRM. However, efforts should be made to deal with changes of the river system affected by the operation of engineering measures, in addition to escalatory development of new demands associated with socio-economic development.

  11. Planning for Regional Water Resources in Northwest China Using a Dynamic Simulation Model (United States)

    Chen, C.; Kalra, A.; Ahmad, S.


    Problem of water scarcity is prominent in northwest China due to its typical desert climate. Exceedence of sustainable yield of groundwater resources has resulted in groundwater depletion, which has raised a series of issues such as drying wells, increasing pumping costs and environmental damage. With a rapid agricultural and economic development, population increase has added extra stress on available water resources by increasing municipal, agricultural and industrial demands. This necessitates efficient water resources management strategies with better understanding of the causes of water stress and options for sustainable development of economy and management of environment. This study focuses on simulating the water supply and demand, under the influence of changing climate, for Shanshan County, located in northwest of China. A dynamic simulation model is developed using the modeling tool Stella for monthly water balance for the period ranging from 2000-2030. Different future water demand and supply scenarios are developed to represent: (1) base scenario- with current practices; (2) change of the primary water source; (3) improvement of irrigation efficiency; (4) reduction of irrigation area; and (5) reduction of industrial water demand. The results indicate that besides growing demand, the low water use efficiency and low level of water reuse are the primary concerns for water scarcity. Groundwater recharge and abstraction could be balanced by 2030, by reducing industrial demand by 50% and using high efficiency irrigation for agriculture. The model provided a better understanding of the effect of different policies and can help in identifying water resources management strategies.

  12. Sustainability is possible despite greed - Exploring the nexus between profitability and sustainability in common pool resource systems. (United States)

    Osten, Friedrich Burkhard von der; Kirley, Michael; Miller, Tim


    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.

  13. Semantic Synchronization of Key Registers in a Model for Drinking Water Resources Management

    Directory of Open Access Journals (Sweden)

    B. Drašković


    Full Text Available Research was oriented to spatial-cadastral information-presentation system (SCIPS and its application to the process of drinking water resources management, with the aim of improving the quality and availability of spatial and other relevant data about these resources. Authors define a model of drinking water resources management on a SCIPS platform, which improves the efficiency of information exchange in the individual interactions of social, government and private participants witch supply users with drinking water. The model is oriented to achieving a high level of availability and multiple uses of data in a wider geographic area based on the principles of cooperation, coordination and collaboration of various elements in a drinking water distribution system. Application of that model, in which key registers are semantically synchronized, may provide more rational and more sustainable usage of drinking water resources and avoiding of potential conflicts of interest or jurisdiction over those resources.

  14. Water-controlled wealth of nations: Using Water Footprints to Estimate Nations Carrying Capacities and Demographic Sustainability (United States)

    Suweis, Samir; Rinaldo, Andrea; Maritan, Amos; D'Odorico, Paolo


    Population growth is in general constrained by food production, which in turn depends on the access to water resources. At a country level, some populations use more water than they control because of their ability to import food and the virtual water required for its production. Here, we investigate the dependence of demographic growth on available water resources for exporting and importing nations. By quantifying the carrying capacity of nations based on calculations of the virtual water available through the food trade network, we point to the existence of a global water unbalance. We suggest that current export rates will not be maintained and consequently we question the long-run sustainability of the food trade system as a whole. Water rich regions are likely to soon reduce the amount of virtual water they export, thus leaving import-dependent regions without enough water to sustain their populations. We also investigate the potential impact of possible scenarios that might mitigate these effects through (1) cooperative interactions among nations whereby water rich countries maintain a tiny fraction of their food production available for export; (2) changes in consumption patterns; and (3) a positive feedback between demographic growth and technological innovations. We find that these strategies may indeed reduce the vulnerability of water-controlled societies.

  15. Integrating science, policy and stakeholder perspectives for water resource management (United States)

    Barbour, Emily; Allan, Andrew; Whitehead, Paul; Salehin, Mashfiqus; Lazzar, Attila; Lim, Michelle; Munsur Rahman, Md.


    Successful management of water resources requires an integrated approach considering the complex relationships between different biophysical processes, governance frameworks and socio-economic factors. The Ecosystem Services for Poverty Alleviation (ESPA) Deltas project has developed a range of socio-economic scenarios using a participatory approach, and applied these across different biophysical models as well as an integrated environmental, socio-economic model of the Ganges-Brahmaputra-Meghna (GBM) Delta. This work demonstrates a novel approach through the consideration of multiple ecosystem services and related socio-economic factors in the development of scenarios; the application of these to multiple models at multiple scales; and the participatory approach to improve project outcomes and engage national level stakeholders and policy makers. Scenarios can assist in planning for an uncertain future through exploring plausible alternatives. To adequately assess the potential impacts of future changes and management strategies on water resources, the wider biophysical, socio-economic and governance context needs to be considered. A series of stakeholder workshops have been held in Bangladesh to identify issues of main concern relating to the GBM Delta; to iteratively develop scenario narratives for business as usual, less sustainable, and more sustainable development pathways; and to translate these qualitative scenarios into a quantitative form suitable for analysis. The combined impact of these scenarios and climate change on water quantity and quality within the GBM Basin are demonstrated. Results suggest that climate change is likely to impact on both peak and low flows to a greater extent than most socio-economic changes. However, the diversion of water from the Ganges and Brahmaputra has the potential to significantly impact on water availability in Bangladesh depending on the timing and quantity of diversions. Both climate change and socio

  17. Water Electrolysis for In-Situ Resource Utilization (ISRU) (United States)

    Lee, Kristopher A.


    Sending humans to Mars for any significant amount of time will require capabilities and technologies that enable Earth independence. To move towards this independence, the resources found on Mars must be utilized to produce the items needed to sustain humans away from Earth. To accomplish this task, NASA is studying In Situ Resource Utilization (ISRU) systems and techniques to make use of the atmospheric carbon dioxide and the water found on Mars. Among other things, these substances can be harvested and processed to make oxygen and methane. Oxygen is essential, not only for sustaining the lives of the crew on Mars, but also as the oxidizer for an oxygen-methane propulsion system that could be utilized on a Mars ascent vehicle. Given the presence of water on Mars, the electrolysis of water is a common technique to produce the desired oxygen. Towards this goal, NASA designed and developed a Proton Exchange Membrane (PEM) water electrolysis system, which was originally slated to produce oxygen for propulsion and fuel cell use in the Mars Atmosphere and Regolith COllector/PrOcessor for Lander Operations (MARCO POLO) project. As part of the Human Exploration Spacecraft Testbed for Integration and Advancement (HESTIA) project, this same electrolysis system, originally targeted at enabling in situ propulsion and power, operated in a life-support scenario. During HESTIA testing at Johnson Space Center, the electrolysis system supplied oxygen to a chamber simulating a habitat housing four crewmembers. Inside the chamber, oxygen was removed from the atmosphere to simulate consumption by the crew, and the electrolysis system's oxygen was added to replenish it. The electrolysis system operated nominally throughout the duration of the HESTIA test campaign, and the oxygen levels in the life support chamber were maintained at the desired levels.

  18. Integrated management of water resources in urban water system: Water Sensitive Urban Development as a strategic approach

    Directory of Open Access Journals (Sweden)

    Juan Joaquín Suárez López


    Full Text Available The urban environment has to be concerned with the integrated water resources management, which necessarily includes the concept of basin unity and governance.  The traditional urban water cycle framework, which includes water supply, sewerage and wastewater treatment services, is being replaced by a holistic and systemic concept, where water is associated with urbanism and sustainability policies. This global point of view cannot be ignored as new regulations demand systemic and environmental approaches to the administrations, for instance, in the management of urban drainage and sewerage systems. The practical expression of this whole cluster interactions is beginning to take shape in several countries, with the definition of Low Impact Development and Water Sensitivity Urban Design concepts. Intends to integrate this new strategic approach under the name: “Water Sensitive Urban Development” (WSUD. With WSUD approach, the current urban water systems (originally conceived under the traditional concept of urban water cycle can be transformed, conceptual and physically, for an integrated management of the urban water system in new models of sustainable urban development. A WSUD implementing new approach to the management of pollution associated with stormwater in the urban water system is also presented, including advances in environmental regulations and incorporation of several techniques in Spain.

  20. Cyanobacteria: A Precious Bio-resource in Agriculture, Ecosystem, and Environmental Sustainability (United States)

    Singh, Jay Shankar; Kumar, Arun; Rai, Amar N.; Singh, Devendra P.


    Keeping in view, the challenges concerning agro-ecosystem and environment, the recent developments in biotechnology offers a more reliable approach to address the food security for future generations and also resolve the complex environmental problems. Several unique features of cyanobacteria such as oxygenic photosynthesis, high biomass yield, growth on non-arable lands and a wide variety of water sources (contaminated and polluted waters), generation of useful by-products and bio-fuels, enhancing the soil fertility and reducing green house gas emissions, have collectively offered these bio-agents as the precious bio-resource for sustainable development. Cyanobacterial biomass is the effective bio-fertilizer source to improve soil physico-chemical characteristics such as water-holding capacity and mineral nutrient status of the degraded lands. The unique characteristics of cyanobacteria include their ubiquity presence, short generation time and capability to fix the atmospheric N2. Similar to other prokaryotic bacteria, the cyanobacteria are increasingly applied as bio-inoculants for improving soil fertility and environmental quality. Genetically engineered cyanobacteria have been devised with the novel genes for the production of a number of bio-fuels such as bio-diesel, bio-hydrogen, bio-methane, synga, and therefore, open new avenues for the generation of bio-fuels in the economically sustainable manner. This review is an effort to enlist the valuable information about the qualities of cyanobacteria and their potential role in solving the agricultural and environmental problems for the future welfare of the planet.

  7. Water Resources Management for Shale Energy Development (United States)

    Yoxtheimer, D.


    The increase in the exploration and extraction of hydrocarbons, especially natural gas, from shale formations has been facilitated by advents in horizontal drilling and hydraulic fracturing technologies. Shale energy resources are very promising as an abundant energy source, though environmental challenges exist with their development, including potential adverse impacts to water quality. The well drilling and construction process itself has the potential to impact groundwater quality, however if proper protocols are followed and well integrity is established then impacts such as methane migration or drilling fluids releases can be minimized. Once a shale well has been drilled and hydraulically fractured, approximately 10-50% of the volume of injected fluids (flowback fluids) may flow out of the well initially with continued generation of fluids (produced fluids) throughout the well's productive life. Produced fluid TDS concentrations often exceed 200,000 mg/L, with elevated levels of strontium (Sr), bromide (Br), sodium (Na), calcium (Ca), barium (Ba), chloride (Cl), radionuclides originating from the shale formation as well as fracturing additives. Storing, managing and properly disposisng of these fluids is critical to ensure water resources are not impacted by unintended releases. The most recent data in Pennsylvania suggests an estimated 85% of the produced fluids were being recycled for hydraulic fracturing operations, while many other states reuse less than 50% of these fluids and rely moreso on underground injection wells for disposal. Over the last few years there has been a shift to reuse more produced fluids during well fracturing operations in shale plays around the U.S., which has a combination of economic, regulatory, environmental, and technological drivers. The reuse of water is cost-competitive with sourcing of fresh water and disposal of flowback, especially when considering the costs of advanced treatment to or disposal well injection and lessens

  8. Increasing life expectancy of water resources literature (United States)

    Heistermann, M.; Francke, T.; Georgi, C.; Bronstert, A.


    In a study from 2008, Larivière and colleagues showed, for the field of natural sciences and engineering, that the median age of cited references is increasing over time. This result was considered counterintuitive: with the advent of electronic search engines, online journal issues and open access publications, one could have expected that cited literature is becoming younger. That study has motivated us to take a closer look at the changes in the age distribution of references that have been cited in water resources journals since 1965. Not only could we confirm the findings of Larivière and colleagues. We were also able to show that the aging is mainly happening in the oldest 10-25% of an average reference list. This is consistent with our analysis of top-cited papers in the field of water resources. Rankings based on total citations since 1965 consistently show the dominance of old literature, including text books and research papers in equal shares. For most top-cited old-timers, citations are still growing exponentially. There is strong evidence that most citations are attracted by publications that introduced methods which meanwhile belong to the standard toolset of researchers and practitioners in the field of water resources. Although we think that this trend should not be overinterpreted as a sign of stagnancy, there might be cause for concern regarding how authors select their references. We question the increasing citation of textbook knowledge as it holds the risk that reference lists become overcrowded, and that the readability of papers deteriorates.

  9. Risk forewarning of regional development sustainability based on a natural resources and environmental carrying index in China (United States)

    Fan, Jie; Wang, Yafei; Ouyang, Zhiyun; Li, Lijuan; Xu, Yong; Zhang, Wenzhong; Wang, Chuansheng; Xu, Weihua; Li, Jiuyi; Yu, Jianhui; Zhou, Kan


    It is a matter of public consensus that China's high growth rate has been achieved at the expense of natural resources and the environment, leading to serious risks to sustainability. This research, which proposes a theoretical model to forewarn of risks to regional developmental sustainability in China, constitutes the first empirical evaluation of this to be undertaken there. The results show that: (a) the areas at risk cover almost 43% of the land and 44% of the population of mainland China. In those areas, 83.56% of people at risk are threatened by the low carrying capacity of the environment and limited water resources. (b) With 70% of the total population living in "at risk" areas, urbanization zones remain as the primary category suffering from overload across China. Extensive industrialization has resulted in environmental pollution, which contributes the most to the forewarning status, while the secondary cause is found to be the special coupling of the scarcity of natural water resources and their inefficient use. In addition, most urban conglomerations suffer from pollution by industrial production and household consumption, which tends to extend to their surrounding agricultural areas. Extensive mineral exploitation in ecologically fragile areas has made them increasingly more vulnerable to disturbances from their neighboring resource-driven urban areas. The paper uses these findings to suggest how to intensify the special regulatory administration of resources and the environment, and to transform approaches to industrialization, in order to address sustainable development issues in developing countries.

  15. Water Budgets: Foundations for Effective Water-Resources and Environmental Management (United States)

    Healy, Richard W.; Winter, Thomas C.; LaBaugh, James W.; Franke, O. Lehn


    INTRODUCTION Water budgets provide a means for evaluating availability and sustainability of a water supply. A water budget simply states that the rate of change in water stored in an area, such as a watershed, is balanced by the rate at which water flows into and out of the area. An understanding of water budgets and underlying hydrologic processes provides a foundation for effective water-resource and environmental planning and management. Observed changes in water budgets of an area over time can be used to assess the effects of climate variability and human activities on water resources. Comparison of water budgets from different areas allows the effects of factors such as geology, soils, vegetation, and land use on the hydrologic cycle to be quantified. Human activities affect the natural hydrologic cycle in many ways. Modifications of the land to accommodate agriculture, such as installation of drainage and irrigation systems, alter infiltration, runoff, evaporation, and plant transpiration rates. Buildings, roads, and parking lots in urban areas tend to increase runoff and decrease infiltration. Dams reduce flooding in many areas. Water budgets provide a basis for assessing how a natural or human-induced change in one part of the hydrologic cycle may affect other aspects of the cycle. This report provides an overview and qualitative description of water budgets as foundations for effective water-resources and environmental management of freshwater hydrologic systems. Perhaps of most interest to the hydrologic community, the concepts presented are also relevant to the fields of agriculture, atmospheric studies, meteorology, climatology, ecology, limnology, mining, water supply, flood control, reservoir management, wetland studies, pollution control, and other areas of science, society, and industry. The first part of the report describes water storage and movement in the atmosphere, on land surface, and in the subsurface, as well as water exchange among these

  16. Ethnographic Approaches to Understanding Social Sustainability in Small-scale Water Systems (United States)

    Wutich, A.


    Social sustainability is an important, but often neglected, aspect of determining the success of small-scale water systems. This paper reviews ethnographic approaches for understanding how indigenous knowledge enhances social sustainability of small-scale water systems, particularly in small-scale water systems threatened by water scarcity. After reviewing the literature on common-pool and traditional resource management strategies, the paper will focus on the case of a community-managed small-scale water system in Cochabamba, Bolivia. This study uses ethnographic evidence to demonstrate how indigenous institutions can be used to manage a small-scale urban water system sustainably. Several factors were crucial to the institution's success. First, indigenous residents had previous experience with common management of rural irrigation systems which they were able to adapt for use in an urban environment. Second, institutional rules were designed to prioritize the conservation of the water source. Third, indigenous Andean social values of uniformity, regularity, and transparency ensured that community members perceived the system as legitimate and complied with community rules. Fourth, self-governance enabled community members to quickly adapt to changing environmental conditions, such as seasonal scarcity and groundwater overdraft. The paper concludes with a discussion of the promise and limitations of ethnographic approaches and indigenous knowledge for understanding social sustainability in small-scale water systems.

    Full Text Available Community knowledge and local institutions play a significant role in sustainable comanagement, use and conservation of natural resources. Looking to the importance of these resources, a project, funded by the National Innovation Foundation (NIF, Ahmedabad, India was implemented to document the community knowledge associated with agriculture and natural resources in few selected Monpa tribe dominating villages of West Kameng and Tawang Districts of Arunachal Pradesh, India. Dynamics of various indigenous practices, gender role, culture and informal rural social institutions, cultural edges significantly contribute in managing and using the natural resources sustainably. Experiential learning and location specific knowledge play a pivotal role in ecosystem sustainability. Study also indicates the synergistic relation existing between local knowledge and ecological edges, thereby helping in sustaining livelihood in high altitude. Indigenous resource management systems are not mere traditions but adaptive responses that have evolved over time.

  1. A pathway to a more sustainable water sector: sustainability-based asset management. (United States)

    Marlow, D R; Beale, D J; Burn, S


    The water sectors of many countries are faced with the need to address simultaneously two overarching challenges; the need to undertake effective asset management coupled with the broader need to evolve business processes so as to embrace sustainability principles. Research has thus been undertaken into the role sustainability principles play in asset management. As part of this research, a series of 25 in-depth interviews were undertaken with water sector professionals from around Australia. Drawing on the results of these interviews, this paper outlines the conceptual relationship between asset management and sustainability along with a synthesis of the relevant opinions voiced in the interviews. The interviews indicated that the participating water authorities have made a strong commitment to sustainability, but there is a need to facilitate change processes to embed sustainability principles into business as usual practices. Interviewees also noted that asset management and sustainability are interlinked from a number of perspectives, especially in the way decision making is undertaken with respect to assets and service provision. The interviews also provided insights into the research needed to develop a holistic sustainability-based asset management framework.

  2. OysterFutures: Integrating Stakeholder Objectives with Natural System Models to Promote Sustainable Natural Resource Policy (United States)

    North, E. W.; Blair, J.; Cornwell, J. C.; Freitag, A. E.; Gawde, R. K.; Hartley, T. W.; Hood, R. R.; Jones, R. M.; Miller, T. J.; Thomas, J. E.; Wainger, L. A.; Wilberg, M. J.


    Achieving effective natural resource management is challenged by multiple and often competing objectives, a restricted set of policy options, and uncertainty in the performance of those options. Yet, managers need policies that allow continued use of natural resources while ensuring access for future generations and maintenance of ecosystem services. Formal approaches are needed that will assist managers and stakeholders in choosing policy options that have a high likelihood of achieving social, ecological, and economic goals. The goal of this project, OysterFutures, is to address this need by improving the use of predictive models to support sustainable natural resource policy and management. A stakeholder-centered process will be used to build an integrated model that combines estuarine physics, oyster life history, and the ecosystem services that oysters provide (e.g., harvest, water quality) to forecast outcomes under alternative management strategies. Through a series of facilitated meetings, stakeholders will participate in a science-based collaborative process which will allow them to project how well policies are expected to meet their objectives using the integrated model. This iterative process will ensure that the model will incorporate the complex human uses of the ecosystem as well as focus on the outcomes most important to the stakeholders. In addition, a study of the socioeconomic drivers of stakeholder involvement, information flow, use and influence, and policy formation will be undertaken to improve the process, enhance implementation success of recommended policies, and provide new ideas for integrating natural and social sciences, and scientists, in sustainable resource management. In this presentation, the strategy for integrating natural system models, stakeholder views, and sociological studies as well as methods for selecting stakeholders and facilitating stakeholder meetings will be described and discussed.

  3. Greenlandic water and sanitation-a context oriented analysis of system challenges towards local sustainable development. (United States)

    Hendriksen, Kåre; Hoffmann, Birgitte


    Today, as Greenland focuses on more economic and cultural autonomy, the continued development of societal infrastructure systems is vital. At the same time, pressure is put on the systems by a lack of financial resources and locally based professional competences as well as new market-based forms of organization. Against this background, the article discusses the challenges facing Greenland's self-rule in relation to further develop the existing water and wastewater systems so that they can contribute to the sustainable development of Greenland. The article reviews the historical development of the water supply and wastewater system. This leads to an analysis of the sectorisation, which in recent decades has reorganized the Greenlandic infrastructures, and of how this process is influencing local sustainable development. The article discusses the socio-economic and human impacts and points to the need for developing the water and sanitation system to support not only hygiene and health, but also local sustainable development.

  4. Water Policy Reforms in South Korea: A Historical Review and Ongoing Challenges for Sustainable Water Governance and Management

    Directory of Open Access Journals (Sweden)

    Ik-Chang Choi


    Full Text Available This study aims to provide an opinion on the state-of-the-art of changes and reforms of water policies in South Korea, as well as the challenges along with their implications for sustainable water governance and management. In parallel with change in water resource characteristics generated by physical, environmental and socio-economic challenges such as: (1 uncertainties about climate change (flooding and drought including seasonal and regional variation in precipitation; (2 significant increase in water use caused by rapid urbanization and population growth in industrialized urban areas; (3 inadequate water pricing mechanism which covers only around 80% of the production cost and makes it harder to maintain water systems; and (4 recursive water quality degradation and conflicts over water rights between regions resulting from non-point source pollution in highland versus lowland areas, Korean water policies have been developed through diverse reforms over 100 years. Nevertheless, new challenges for sustainable water management are continuously emerging. To meet those challenges we provide two ideas: (i provider-gets-principle (payment for ecosystem services of cost-benefit sharing among stakeholders who benefit from water use; and (ii water pricing applying full-cost pricing-principle internalizing environmental externalities caused by the intensive water use. Funds secured from the application of those methods would facilitate: (1 support for upstream (rural low income householders suffering from economic restrictions; (2 improvement in water facilities; and (3 efficient water use and demand management in South Korea’s water sectors. We expect that this paper can examine the lessons relevant to challenges that South Korea faces and offer some implications on the formulation of new integration and further reforms of the institutions, laws and organizations responsible for managing water resources in South Korea.

  7. Collaborative Research for Water Resource Management under Climate Change Conditions (United States)

    Brundiers, K.; Garfin, G. M.; Gober, P.; Basile, G.; Bark, R. H.


    We present an ongoing project to co-produce science and policy called Collaborative Planning for Climate Change: An Integrated Approach to Water-Planning, Climate Downscaling, and Robust Decision-Making. The project responds to motivations related to dealing with sustainability challenges in research and practice: (a) state and municipal water managers seek research that addresses their planning needs; (b) the scientific literature and funding agencies call for more meaningful engagement between science and policy communities, in ways that address user needs, while advancing basic research; and (c) empirical research contributes to methods for the design and implementation of collaborative projects. To understand how climate change might impact water resources and management in the Southwest US, our project convenes local, state, and federal water management practitioners with climate-, hydrology-, policy-, and decision scientists. Three areas of research inform this collaboration: (a) the role of paleo-hydrology in water resources scenario construction; (b) the types of uncertainties that impact decision-making beyond climate and modeling uncertainty; and (c) basin-scale statistical and dynamical downscaling of climate models to generate hydrologic projections for regional water resources planning. The project engages all participants in the research process, from research design to workshops that build capacity for understanding data generation and sources of uncertainty to the discussion of water management decision contexts. A team of “science-practice translators” facilitates the collaboration between academic and professional communities. In this presentation we contextualize the challenges and opportunities of use-inspired science-policy research collaborations by contrasting the initial project design with the process of implementation. We draw from two sources to derive lessons learned: literature on collaborative research, and evaluations provided by

  8. Integrated water resources management : A case study in the Hehei river basin, China (United States)

    Jia, Siqi; Deng, Xiangzheng


    The lack of water resources experienced in different parts of the world has now been recognized and analyzed by different international organizations such as WHO, the World Bank, etc. Add to this the growing urbanization and the fast socio-economic development, the water supply of many urban areas is already or will be severely threatened. Recently published documents from the UN Environmental Program confirms that severe water shortage affects 400 million people today and will affect 4 billion people by 2050. Water nowadays is getting scarce, and access to clean drinking water and water for agricultural usage is unequally distributed. The biggest opportunity and challenge for future water management is how to achieve water sustainability to reduce water consumption. Integrated Water Resources Management (IWRM) is a process which promotes the coordinated development and management of water, land and related resources in order to maximize economic and social welfare in an equitable manner without compromising the sustainability of vital ecosystems. We take the Heibe river basin where agriculture water there accounted for 90% of total water consumption as an example to study the impacts of IWRM on regional water resources. We calculated the elasticity of substitution values between labor and land, water by each irrigation areas to find the variable elastic value among irrigation areas, and the water-use efficiency based on NPP estimation with the C-fix model and WUE estimation with NPP and ET. The empirical analysis indicated that the moderate scale of farmland is 0.27-0.53hm2 under the condition of technical efficiency of irrigation water and production. Agricultural water use accounted for 94% of the social and economic water consumption in 2012, but water efficiency and water productivity were both at a low stage. In conclusion, land use forms at present in Heihe river basin have a detrimental impact on the availability of ecological water use. promoting water

  9. Water resources of southeastern Bucks County, Pennsylvania (United States)

    Graham, Jack B.; Mangan, John W.; White, Walter F.


    This report has been prepared as a contribution to the development of southeastern Bucks County, Pa. It summarizes available information on the water resources of this 90-square mile area and evaluates current supplies. Future development of the area may change both the available quantity and the quality of the water supply. The effective development of the area demands a continuing knowledge of the water used and the potential quantity and quality of water available from both underground and surface sources. The area is strategically important to a great industrial section of the Bast. Its eastern boundary is a 26-mile segment of the Delaware River along the extreme southeastern border of Bucks County, Pa. (fig. 1). The present.population of the area is about 40,000, including 24,800 in Bristol Borough and Township and 6,770 in Morrisville. The area is traversed by both the Pennsylvania and the Reading Railroads and also by U.S. Highways 1 and 13. These are main transportation routes connecting the great market outlets of Philadelphia and New York. The Delaware River'is navigable from Morrisville to the sea. The area is only a short distance upstream from the Port of Philadelphia, which ranks second only to New York as the most important seaport in the United States. The area is mostly flat, open land 10 to 60 feet above mean sea level. It contains several large Industries, concentrated chiefly in the Bristol area (pi. 1). There are also scattered industries in the Morrisville, Langhorne, and Bensalem areas. However, Bucks County retains some of the characteristics of a farming region. Truck farming and gardening are still carried on to a considerable extent. Along Delaware River below Morrisville the mining of sand and gravel is an Important industry. The facts summarized in this report have been accumulated over a period of 25 years or more by Federal, State, and local agencies in connection with Investigations for other purposes. Most of the data used in this

  13. Water management in Republika Srpska in the function of developing sustainability

    Directory of Open Access Journals (Sweden)

    Đukić Veljko N.


    Full Text Available Sustainability, as strategic development approach in the world in the past decade- has become an inevitable response to the growing pressure to the available natural resources. If we separate four key problems of humanity -water, food, energy and the environment- we face that the solution in the other three crisis complex decisively depends on the water: the food and energy production depends on water, the environment protection is the most sensitive in the water eco-systems. Therefore, the fact that, 'the water has become the resource of The 21st Century', Dublin Conference on Development and Agenda 21 (Chapter 1.3.2 provided the definition: 'The sustainability has become basic principle to all development strategies, especially in the development of the water resources domain.' The key problem, which makes water potentials of RS relative is extremely big space and time distribution of the rainfall and outflow. The most concise: the water distribution is such that it lacks water where it is most needed (in the northern part of RS where the most valuable land resources are and the industrial potentials, and the flows are the poorest in the time of the year (vegetation, warm season when the needs for water are the highest and when the most serious problems on water quality protection are. Having in mind the fact that, Republic of Srpska and Bosnia and Herzegovina have insufficient monitoring data available, as well as the level of the development of the method for evaluation of the ecological status, in the overall territory of Republic of Srpska, actually in two parts of the watershed; it is not possible to achieve the full level of comparison and high level of reliability of the results for evaluation of ecological status of the ground waters. Until we overcome the shortage of the existing system, it is necessary to establish method to define the level of reliability during the evaluation of ecological and chemical status.

  14. Sustained adoption of water, sanitation and hygiene interventions: systematic review. (United States)

    Martin, Nina A; Hulland, Kristyna R S; Dreibelbis, Robert; Sultana, Farhana; Winch, Peter J


    To understand factors that influence sustained adoption of water, sanitation and hygiene (WASH) technologies or behaviours. Systematic review of the current literature. Articles were gathered from databases of peer-reviewed articles and grey literature, and screened for relevance. After exclusion, we created a descriptive map of 148 articles and analysed in-depth 44 articles that had an explicit focus on promoting or evaluating sustained adoption or programme sustainability. Twenty-two of these articles met our definition of measuring sustained adoption. Definitions of sustained adoption varied widely and were often inadequate, making comparison of sustained adoption across studies difficult. The time frame for measurements of sustained adoption is frequently inadequate for examination of longer-term behaviour change. Ideally, an evaluation should specify the project period and describe the context surrounding adoption, make measurements at multiple time points, diversify measurement methods and describe and measure a range of factors affecting sustained adoption. Additional consideration needs to be given to developing behaviour change models that emphasise factors related to sustained adoption, and how they differ from those related to initial adoption. © 2017 John Wiley & Sons Ltd.

  16. Water footprints of cities - indicators for sustainable consumption and production (United States)

    Hoff, H.; Döll, P.; Fader, M.; Gerten, D.; Hauser, S.; Siebert, S.


    Water footprints have been proposed as sustainability indicators, relating the consumption of goods like food to the amount of water necessary for their production and the impacts of that water use in the source regions. We further developed the existing water footprint methodology, by globally resolving virtual water flows from production to consumption regions for major food crops at 5 arcmin spatial resolution. We distinguished domestic and international flows, and assessed local impacts of export production. Applying this method to three exemplary cities, Berlin, Delhi and Lagos, we find major differences in amounts, composition, and origin of green and blue virtual water imports, due to differences in diets, trade integration and crop water productivities in the source regions. While almost all of Delhi's and Lagos' virtual water imports are of domestic origin, Berlin on average imports from more than 4000 km distance, in particular soy (livestock feed), coffee and cocoa. While 42% of Delhi's virtual water imports are blue water based, the fractions for Berlin and Lagos are 2 and 0.5%, respectively, roughly equal to the water volumes abstracted in these two cities for domestic water use. Some of the external source regions of Berlin's virtual water imports appear to be critically water scarce and/or food insecure. However, for deriving recommendations on sustainable consumption and trade, further analysis of context-specific costs and benefits associated with export production will be required.

  17. Basic criteria for a sustainable water management at the U.S.-México border: the case of ambos Nogales

    Directory of Open Access Journals (Sweden)

    Luis Ernesto Cervera Gómez


    Full Text Available This article aims to analyze some basic criteria for a sustainable use of water in an international watershed shared by Mexico and the United States. The study area comprises the region of Ambos Nogales, which is located inside the Upper Santa Cruz River Basin. This portion of the watershed represents the main ecosystem and the main source of water for urban and rural populations located in this region. Following criteria of sustainability the authors revise and adapt to the case of Ambos Nogales, a set of guidelines proposed by the Pacific Institute for Studies in Development, Environment, and Security. These guidelines include the following elements: basic water requirements needed to maintain quality of life in the population and the health of ecosystems; water quality that meets certain minimum standards; human actions and their impact on long-term renewability of freshwater stocks and flows; collection of data concerning water resources, use and quality of water; institutional mechanisms to prevent and resolve conflicts; and a democratic process of water-planning and decision-making. These twin cities have a long history of cooperation and conflict linked to water resources, which makes available enough information to create a diagnostic about the water management inside a binational arena, and allowing to explore possibilities for a better water resources management under a sustainable regime and from an international perspective. Keywords: Sustainability, binational water management, ambos Nogales region.

  19. Development of an integrated water resources management plan for the Lake Manyara sub-basin, Northern Tanzania (United States)

    Ngana, J. O.; Mwalyosi, R. B. B.; Madulu, N. F.; Yanda, P. Z.

    Water resources management in Lake Manyara sub-basin is an issue of very high significance as the sub-basin hosts a number of national and global assets of great socio-cultural, ecological and economic values. The sub-basin comprise of a Biosphere Reserve with boosting tourism from Lake Manyara National Park with a variety of wildlife population, large livestock population and highly fertile land for agricultural production. The prevailing system of uncoordinated water resources management in the sub-basin cannot sustain the ever increasing water needs of the various expanding sectors, therefore a strategy must be sought to integrate the various sectoral needs against the available water resources in order to attain both economic and ecological sustainability. Through participatory approach with the stakeholders, the study has established key issues, demonstrated considerable experience in water resources management in the sub-basin including existence of water boards, water committees in some districts as well as land resources management practices However, a number of constraints were noted which inhibit sustainable water resources management including ignorance of water policies, conflicting sectoral policies, lack of coordination between sectors, high in migration rates into the basin, heavy in migration of livestock, conflicts between sectors, poor land use resulting in soil erosion and sedimentation, lack of comprehensive data base on water resources and water needs for : domestic, tourism, livestock, irrigation, wild life and environmental flows. As a way forward it was recommended that a basin wide legally mandated body (involving all levels) be established to oversee water use in the sub-basin. Other strategies include capacity building of stakeholders on water natural resources management policies, water rights and enforcement of laws. This progress report paper highlights the wealth of knowledge that stakeholders possess on water resources management and

  20. Estimating Companies and Sectoral Sustainability in Resource Consumption

    Directory of Open Access Journals (Sweden)

    Ramona CRUCERU


    Full Text Available The economic growth during the last decades has been associated with a continuously increasing intensive use of material resources, in spite of the technological progress. The historical data over a century reveals that the current economic system supports to a certain degree the inefficient use of resources by allowing large waste, low conversions factors, pricing below true costs. The paper intends to address some interesting points based on observations derived from statistical evidence on resource indicators. The resource efficiency indicators relate to the following broad categories - overall (national resource consumption/ efficiency and industry resource consumption/efficiency. In the paper, the first category is addressed by involving the resource productivity - measured as the volume of Gross Domestic Product in market prices (GDP over Domestic Material Consumption (DMC, it is studied for the period 2000-2009 based on the Eurostat database. The indicator has increased by 16 %, with a slightly larger rhythm as compared to the growth in GDP (around 12 % over the same period, indicating that in the EU27 there was placed in a separate and decoupled growth pattern from that one of domestic resource consumption. Yet the evolution was very specific at the member states’ level depending on domestic context – the economic structure, the competitiveness level, the impact of financial crisis etc. Even if the most frequently used to estimate the efficiency of the resource consumption is resource productivity, the link with other time series or structure indicators bring to light new perspectives in revealing the patterns of consumption and policy actions to improve the resource efficient use.
