  • Water scarcity projections

    Things are changing globally — and long term trends are not very encouraging. The map here and its included commentary tell an extremely complex story. Water scarcity already affects every continent and around 2.8 billion people around the world at least one month out of every year. More than 1.2 billion people lack access to clean drinking water. It mostly affects arid and deserted areas, ...

  • Water policy at science–policy interface – challenges and opportunities for India

    Water scarcity is a serious concern in emerging economies, as it impacts human development, livelihoods, environment and economic growth. Policies should be formulated in a way that reflects the problem of water scarcity and is oriented towards providing solutions. The science–policy interface can play a key role in translating scientific knowledge into policy action and in mitigating water ...

  • Climate Change-Induced Water Scarcity: A Threat to Human Health

    Climate change might affect the development of water scarcity least in some areas of the world. Water scarcity means not only the availability but also the quality of water and sanitation. Climate change might reduce the capacity of the state to provide health care to the population. Thereby, climate change has direct and indirect impacts on human security and hence health effects may result from ...

  • Coping with water scarcity. An action framework for agriculture and food security

    This report aims to provide a conceptual framework to address food security under conditions of water scarcity in agriculture. The purpose of this report is twofold. First, to define a water accounting framework that allows water scarcity to be interpreted objectively. Second, to indicate where and how agricultural water management can play a more proactive and effective role in response to ...

  • The temporal–spatial assessment of water scarcity with the Water Poverty Index: a study in the middle basin of the Heihe River, northwest China

    This paper details an application of the Water Poverty Index (WPI) to evaluate the state of water resources in an inland river basin using a case study of the Heihe River Basin (HRB) located in northwest China. The WPI includes five components (resources, access, capacity, use, and environment) and has 13 indicators; each indicator is assigned an equal weighting. The selected set of ...

  • Return of the Leviathan? Hydropolitics in the developing world revisited

    The paper focuses on the evolution of water management regimes, water scarcity, and the transition to a new water legislation in South Africa that occurred with the passing of the 1998 National Water Act. It takes issue with the analysis offered by Turton & Meissner in their 2002 article ‘The hydrosocial contract and its manifestation in society: A South African case study’ (in Hydropolitics and ...

  • Evaluating water scarcity in the Southern African Development Community (SADC) region by using a climate moisture index (CMI) indicator

    Increasing water scarcity in the Southern African Development Community (SADC) region has underscored the need to improve our understanding of the management of water resources. Using total evapotranspiration (TET) and precipitation (P) data of the past 16 years this study used a modified version of the climate moisture index (CMI) in order to evaluate water scarcity throughout the SADC region, ...

  • The role of proximity in problem identification: risk of water scarcity in Texas

    This project seeks to determine whether proximity to major water sources (e.g. rivers or lakes) is associated with the public's perception of water scarcity. From a theoretical perspective, this project will aid our collective understanding of problem identification. From a practical perspective, this relationship could help inform decision makers about where support or resistance to a water ...

  • Water Hungry Coal - Burning South Africa’s water to produce electricity

    Safe, affordable and accessible water is regarded as one of our planet’s scarcest natural resources. This is particularly true on the African continent, where water insecurity is often an everyday reality. At the same time, equitable access to water is fundamental to life and human health and well-being. South Africa already struggles with water scarcity, and it is predicted that the ...

  • Environmental change and migration in Sub-Saharan Africa

    Environmental changes are especially pronounced in Sub-Saharan Africa (SSA). Land degradation is nowadays a major concern for 32 countries in Africa, and over 300 million people in SSA face water scarcity (UNEP, 2008). To what extent are environmental factors likely to trigger migration in SSA? To shed some light on the question, this paper provides the latest figures and information. The ...

  • Global Monthly Water Scarcity: Blue Water Footprints versus Blue Water Availability

    Freshwater scarcity is a growing concern, placing considerable importance on the accuracy of indicators used to characterize and map water scarcity worldwide. We improve upon past efforts by using estimates of blue water footprints (consumptive use of ground- and surface water flows) rather than water withdrawals, accounting for the flows needed to sustain critical ecological functions and by ...

  • America`s Water Risk: Water Stress and Climate Variability

    The emerging awareness of the dependence of business on water has resulted in increasing awareness of the concept of “Water Risk” and the diverse ways in which water can pose threats to businesses in certain regions and sectors. Businesses seek to secure sustainable income. To do so, they need to maintain a competitive advantage and brand differentiation. They need secure and stable ...

  • Water markets as a response to scarcity

    Existing water governance systems are proving to be quite ineffective in managing water scarcity, creating severe risk for many aspects of our societies and economies. Water markets are a relatively new and increasingly popular tool in the fight against growing water scarcity. They make a voluntary exchange possible between interested buyers and sellers of water rights. This paper presents ...

  • Challenges of Developing an EU Strategic Approach to Water Scarcity

    Water scarcity is a serious and growing problem in a number of EU Member States. EU water law has traditionally focused on water quality issues. However, the introduction in 2000 of the Water Framework Directive has provided the first coherent legal tool to address water scarcity and this has been supported by further policy aimed directly at water scarcity. However, there are also many local ...

  • Exploring water indices and associated parameters: a case study approach

    In the past 20 years, over 50 water indices have been developed to characterize human-water systems within the frameworks of water scarcity, water poverty, water vulnerability, and water security. This study compares existing water indices in Bangladesh and Sri Lanka to better understand which parameters (or lack thereof) contribute to the usefulness of water indices. Drawing on knowledge about ...

  • Hydropolitics is what societies make of it (or why we need a constructivist approach to the geopolitics of water)

    Although the study of hydropolitics (i.e. the geopolitics of water) is mainly an offshoot of the discipline of International Relations (IR), the use of IR conceptual tools remains largely implicit in the literature. As a result, theoretical exploration has been very limited in hydropolitics and is usually cast within IR's traditional divide between realism and liberalism. This is problematic ...
