This book gives decision makers, health professionals and analysts a comprehensive view of the arguments and challenges associated with establishing the value of drinking-water interventions. The experts who have contributed to this publication provide guidance on assessing the benefits from improving access to safe drinking water and from reducing the burden of water-related diseases. They show how to compare the value of these benefits to the costs of the interventions, with special reference to small-scale drinking water systems.
The geographies of health and development is an emerging sub-discipline, tying in with many of the conceptual, theoretical and practical components of other disciplines working in health, health care, economics, and international development. Spatially and theoretically grounded in geography, this collection offers a fresh perspective on the dialectic relationships between health and development. Health problems in a developing context take on much higher rates of prevalence as a result of the varied cultural, structural and economic vulnerabilities of the people they impact. This book begins by exploring some of the circumstances surrounding the distinctive health inequities currently facing many developing countries, including malaria, maternal mortality and HIV/AIDS. This is followed by a discussion of how matters of physical access and human resource issues and, perhaps most importantly, the challenges of financing, together shape the access and utilization of health care. Examining how the environment interacts to influence the health of the people that live there, the next section includes discussion around challenges of food (in)security, and the importance of clean and uncontaminated water for health. Finally, the book explores the influence of globalization on health, specifically within the urban environment, against the backdrop of global health policy.
A common characteristic of water demand in urban areas worldwide is its inexorable rise over many years; continued growth is projected over coming decades. The chief influencing factors are population growth and migration, together with changes in lifestyle, demographic structure and the possible effects of climate change (the detailed implications of climate change are not yet clear, and anyway will depend on global location, but must at least increase the uncertainty in security of supply). This is compounded by rapid development, creeping urbanization and, in some places, rising standards of living. Meeting this increasing demand from existing resources is self-evidently an uphill struggle, particularly in water stressed/scarce regions in the developed and developing world alike. There are typically two potential responses: either "supply-side" (meeting demand with new resources) or "demand-side" (managing consumptive demand itself to postpone or avoid the need to develop new resources). There is considerable pressure from the general public, regulatory agencies, and some governments to minimise the impacts of new supply projects (e.g. building new reservoirs or inter-regional transfer schemes), implying the emphasis should be shifted towards managing water demand by best utilising the water that is already available. Water Demand Management has been prepared by the academic, government and industry network WATERSAVE. The concept of the book is to assemble a comprehensive picture of demand management topics ranging from technical to social and legal aspects, through expert critical literature reviews. The depth and breadth of coverage is a unique contribution to the field and the book will be an invaluable information source for practitioners and researchers, including water utility engineers/planners, environmental regulators, equipment and service providers, and postgraduates.

This research report presents the findings of the first phase of the action-research project "Models for implementing multiple-use water supply systems for enhanced land and water productivity, rural livelihoods and gender equity." Multipleuse water services, or "mus" in short, is a participatory, integrated and poverty-reduction focused approach in poor rural and peri-urban areas, which takes people's multiple water needs as a starting point for providing integrated services, moving beyond the conventional sectoral barriers of the domestic and productive sectors.
Sub-Saharan Africa, the poorest region worldwide, has only recently begun to fully address the issues of meeting the water needs of its rapidly growing population, to reduce the deepening poverty besetting the region and to accelerate economic growth. The Nile Basin, characterized by sharp spatial and temporal variations in water resources and including countries with different economies, social and political structures and capacities, illustrates the challenges of developing and managing the waters of the Nile River and its tributaries, lakes and wetlands equitably among its 10 riparian countries. Ethiopia, the major source of the Nile but one of the poorest countries in the Nile Basin, has recently begun to implement plans to harness more Nile water through hydroelectric and irrigation development both for national use and for transboundary development as part of the Nile Basin Initiative. The Ethiopian government and communities, by using different management approaches and resources, are trying to boost water, energy and food production, strengthen conservation efforts and mitigate potential repercussions of water resources development. These initiatives and programs have not been comprehensively examined. In this study, the editors address these and other issues surrounding water resources management in all economic and water sectors in Ethiopia within the setting of the Nile Basin, the first comprehensive treatment of this subject. The wide scope of this book is consistent with the tenets of integrated water resources management, which demand that all water uses be managed in an integrated fashion for optimum and sustainable benefits to all water users, both humans and ecosystems. This book reveals the impacts of various resource management approaches and practices in Ethiopia and the Nile Basin. Specifically, it examines how deforestation and prevailing land use practices have exacerbated soil aridity and flood events, why irrigated agriculture and hydropower development have caused floodplain degradation, livelihood hardships and water-related diseases, where industrial and agricultural development is increasingly polluting water resources, how household water supplies can be obtained through rainwater harvesting and the dependence on hydropower reduced through alternative energy sources and how misguided government policies have impeded efforts to deal with these and other challenges. Results reveal dynamic interrelationships between these processes and identify the human and environmental driving forces, which must be understood in effective integrated water resources management. Another unique contribution of this book is the examination of the role of government and communities in managing water resources in Ethiopia. Results show that the top-down approach used by the socialist Derg government in soil and water conservation and social programs exacerbated water problems and reduced community participation. Moreover, the failure of its economic program reduced agricultural production, increasing dependency on relief food and further impeding community initiatives in soil and water conservation activities. Many elements of central planning persist in spite of the decentralization drive by the current government, but there is evidence that integration of the top-down and bottom-up approaches to water resources management is necessary (and feasible) to strengthen and up-scale programs to the national level. The book identifies a number of customary water and soil management practices and institutions that may strengthen especially community-based rainwater harvesting, small-scale irrigation, reforestation, soil and water conservation and flood control efforts. This is an important book for researchers and students of resources management, rural development, hydrology and African studies.
Focusing primarily on understanding the steady-state hydraulics that form the basis of hydraulic design and computer modelling applied in water distribution, Introduction to Urban Water Distribution elaborates the general principles and practices of water distribution in a straightforward way. The workshop problems and design exercise develop a tem
In a short space of time, the right to water has emerged from relative obscurity to claim a prominent place in human rights theory and practice. This book explores this rise descriptively and prescriptively. It analyses the recognition, use and partly impact, of the right to water in international and comparative law, civil society mobilisation and public policy. It also scrutinises the normative implications of the right to water with a focus on challenges and puzzles it creates for law and policymaking. These questions are explored globally and comparatively within different dynamics of the sector - water allocation, water access and urban and rural water reform - and in conjunction with the right to sanitation. This multi-disciplinary volume reveals the diverse ways in which the right to water has been adopted, but also its limitations when faced with the realities of political economy, political ecology and partly, traditional legal thought.
Of the world's 6 billion people, 1.1 billion lack access to safe drinking water. The aim of this booklet is to highlight and promote the right to water as a fundamental human right. It looks at who is affected, the responsibility of governments and the implications for other stakeholders
