  • Structural conditions in German water supply

    Against the background of price controls for drinking water supply utilities in Germany, the comparability of utilities with regard to their specific structural conditions comes into focus. Relevant structural conditions were identified for the two main technical processes, namely water production (WP) and treatment, storage and distribution (TSD). A defined clustering process for comparable ...

  • Water supply in Jordan under drought conditions

    This paper discusses the Mujib Dam reservoir's storage during the drought years of 2007–2009. It has been concluded that the policy of unplanned water release during the dry year 2007, when little attention was paid to the possibility of a continuation of the drought, contributed to the remarkable lack of surface water storage during 2008, another dry year. For better management and planning, ...

  • High frequency monitoring needed to protect UK rivers - Case Study

    The science behind nutrient pollution in rivers is still poorly understood despite the fact that nitrate and phosphate concentrations in the UK’s rivers are mostly unacceptable, although an element of uncertainty exists about what an acceptable level actually is. Key to improving our understanding of the sources and impacts of nutrient pollution is high-resolution monitoring across a broad ...

  • The impact of privatisation on the sustainability of water resources

    More than two and a half millennia ago, the Greek philosopher Thales of Miletus said  “best of everything is water” (Biswas, 2005; p.229). Indeed, water still remains the source of life although the world has changed dramatically. Water is the most important natural resource on our planet Earth. It is the basis of life that all organisms depend on for survival. ...

  • Industry, Fresh Water and Sustainable Development

    Synopsis Industry, Fresh Water, and Sustainable Development is published jointly by the World Business Council for Sustainable Development and the United Nations Environment Programme (UNEP). The growing demands for water for human consumption, agriculture and industry means that fresh water must not be taken for granted, but be carefully used.  Industry has an important ...

  • Water

    Water is the most valuable asset on earth, which determines to a significant extent the development of life in all corners of the world. 95% of the amount of water on earth is chemically bound in rocks making it impossible to utilize and be part of the hydrological cycle. ...

  • Transboundary water allocation under water scarce and uncertain conditions: a stochastic bankruptcy approach

    Designing a feasible and stable water sharing mechanism for transboundary river basins is a big challenge. The stochastic and uncertain characteristics of water flow in these rivers is among the main reasons which make the formation of cooperative coalitions with feasible water allocations and self-enforceable allocation agreements difficult. When the water in these river basins is scarce the ...

  • Sustainable water resource management: the science behind the scene

    Working in the field of research is—in very many respects—challenging and intriguing. In fact, we as researchers are eager to challenge the unknown although we never can reach the ultimate truth. The most we can hope to accomplish is to draw, on the basis of new evidence and understanding, a model of the world that brings us closer to reality than any previous model. Progress along this road is ...

  • Water sector performance under scarcity conditions: a case study of Rajasthan, India

    This paper makes an attempt to assess the water sector under scarcity conditions in the State of Rajasthan. It adopts the criteria of physical, economic, financial and equity performance across sub-sectors. The assessment brought out clearly that no indicator has shown satisfactory performance in any of the sub-sectors. Though the urban drinking water sector is relatively better in performance, a ...

  • The California Water Sustainability Indicators Framework: Draft Final Report

    The Water Sustainability Indicators Framework grew out of regional projects developing indicators for water and watershed condition. The California Water Plan Update 2013 team decided to incorporate sustainability indicators into the Update in response to recommendations from the 2009 Update advisory process. This report describes the work completed in two phases by the UC Davis team between 2011 ...

  • Notes on Sustainable Water Resources: Migration and Global Environmental Change

    This report examines the environmental drivers of migration in the Mediterranean, with particular focus on the role of ecosystem services and the impact of environmental hazards as potential push and pull factors. Environmental drivers are just one set of potential drivers for migration described in the Foresight ‘drivers of migration’ pentagon alongside demographic, social, political ...

  • Assessment of vulnerability of river basins in Ghana to water stress conditions under climate change

    The Falkenmark indicator was used to assess vulnerability of the White Volta (106,000 km2) and Pra (20,023 km2) river basins in Ghana to water stress under climate change for the periods 2006–2035 (representing the 2020s) and 2036–2065 (2050s). The indicator is a commonly used measure of water stress and defines thresholds of 1,700, 1,000 and 500 m3/capita/annum ...

  • Revealing causal pathways to sustainable water service delivery using fsQCA

    This study aimed to build on theory and practice regarding the combinations of conditions that influence water service sustainability when external partners are involved. The study investigates 26 well projects that have been implemented in developing countries with the assistance of Engineers Without Borders-USA (EWB-USA). Using past literature on sustainable water service delivery in ...

  • Risk management of transboundary water resources: sustainable water management of the River Jordan basin area

    The River Jordan basin suffers from regional water scarcity, wide economic discrepancies and a long-lasting dispute over land ownership. Prolonged, widespread unsustainable management has significantly decreased the water flow and aggravated water pollution. The river is now seriously at risk of drying up, with the loss of a unique ecosystem with important religious and cultural significance. ...

  • Communication and the Narrative Basis of Sustainability: Observations from the Municipal Water Sector

    Numerous studies attempt to operationalize sustainability and seek to characterize objective, or at least standardized, metrics of sustainable conditions and/or operations. In this paper, we suggest that sustainability is better viewed as an emergent quality, defined in terms of specific institutions and situations. Observations from the water sector suggest that sustainability is not merely a ...

  • Sustainable water resources management in the Long Bien district of Hanoi, Vietnam

    The accelerated industrialization of Hanoi, Vietnam, coupled with a high population growth rate and changing climatic conditions create increasing pressure on the local water balance. Despite abundant precipitations, overexploitation endangers the groundwater resources, which are not able to sustain an adequate water supply. The present paper presents a sustainable approach for balancing the ...
