Rural Water Systems for Multiple Uses and Livelihood Security


Book Description

Rural Water Systems for Multiple Uses and Livelihood Security covers the technological, institutional, and policy choices for building rural water supply systems that are sustainable from physical, economic, and ecological points-of-view in developing countries. While there is abundant theoretical discourse on designing village water supply schemes as multiple use systems, there is too little understanding of the type of water needs in rural households, how they vary across socio-economic and climatic settings, the extent to which these needs are met by the existing single use water supply schemes, and what mechanisms exist to take care of unmet demands. The case studies presented in the book from different agro ecological regions quantify these benefits under different agro ecological settings, also examining the economic and environmental trade-offs in maximizing benefits. This book demonstrates how various physical and socio-economic processes alter the hydrology of tanks in rural settings, thereby affecting their performance, also including quantitative criteria that can be used to select tanks suitable for rehabilitation. - Covers interdisciplinary topics deftly interwoven in the rural context of varying geo-climatic and socioeconomic situations of people in developing areas - Presents methodologies for quantifying the multiple water use benefits from wetlands and case studies from different agro ecologies using these methodologies to help frame appropriate policies - Provides analysis of the climatic and socioeconomic factors responsible for changes in hydrology of multiple use wetlands in order to help target multiple use water bodies for rehabilitation - Includes implementable models for converting single use water supply systems into multiple use systems




WATER ACCOUNTING FOR WATER GOVERNANCE AND SUSTAINABLE DEVELOPMENT


Book Description

There is growing interest in water accounting, why it is needed, what benefits it brings, and equally important, how it can be put into practice. Water accounting is not a new idea, yet it is an alarmingly simple one. It is about quantifying water resources and uses of water, much like financial accounts provide information on income and expenditure. Interest in water accounting is based on the premise that ‘We cannot plan and manage what we do not measure’ – a statement that few would disagree with. However, given the current focus on water as a precious and limiting resource, the risks of extreme floods and droughts, and water’s central role in the 2030 Agenda, it is difficult to understand why so little attention is given to water accounting and to making sure we have enough water. Indeed, estimates suggest that by 2050, if we continue with our current approach to water management, global water demand will exceed supply by over 40%, which would put at risk 45% of global GDP, 52% of the world’s population, and 40% of grain production (WWDR, 2016). This concern is supported by the World Economic Forum that consistently ranks water crises as a top global risk (WEF, 2015). Reports from South Africa (January 2018) suggesting that Cape Town may be the world’s first major city to face the prospect of running out of water following severe drought, is a timely ‘wake-up call’ for everyone to focus on accounting for water.




Water infrastructure information on federal and state financial assistance.


Book Description

U.S. drinking water and wastewater systems encompass thousands of treatment facilities, collection facilities, and related works, and well over a million miles of pipes and conduits. While the investment, made over decades, in these facilities is enormous, even more funds will be needed in the future to support efforts to maintain clean and safe water. The estimated cost of the investments needed to repair, replace, or upgrade aging facilities, accommodate the nation's growing population, and meet new water quality standards ranges from $300 billion to $1 trillion over the next 20 years, according to various estimates.




Rural Community Water Supply


Book Description

Richard Carter weaves together the myriad of factors that need to come together to make rural water supply truly available to everyone. He concludes that ultimately, systemic change to the global web of injustice that divides this world into rich and poor may be the only way to address the underlying problem.




Toward a Financially Sustainable Irrigation System


Book Description

Water resource management policies worldwide are at a crossroads. On the one hand, a remarkable consensus on the principles of reform has emerged. On the other hand, it has turned out to be difficult to transfer the principles into reality. This document describes the distinctive experience of water reform in the state of Victoria, Australia, which has been a leader in the field. The document is a compelling "insiders' view" by three professionals who played central roles in the process. Although the Victoria experience emerges from a specific natural, cultural, historical and political context, the generic lessons on the technical and political reform procedures and the links between them are of profound relevance to those engaged in the water reform process throughout the world.




Safe Water From Every Tap


Book Description

Small communities violate federal requirements for safe drinking water as much as three times more often than cities. Yet these communities often cannot afford to improve their water service. Safe Water From Every Tap reviews the risks of violating drinking water standards and discusses options for improving water service in small communities. Included are detailed reviews of a wide range of technologies appropriate for treating drinking water in small communities. The book also presents a variety of institutional options for improving the management efficiency and financial stability of water systems.
