Global Water Resource Issues

The world's water resources are coming under increasing stress, a stress that will become critical globally sometime during the next century. This is due to the rapidly rising population demanding more and more water and an increasing level of affluence. The book discusses the background to this issue and the measures to be taken over the next 20-30 years to overcome some of the difficulties that can be foreseen, and the means of avoiding others, such as the hazard of floods. It looks at the water resource and its assessment and management in an integrated fashion. It deals with the requirements of agriculture and of rural and urban societies and to a lesser extent with those of industry and power, against the background of the needs of the natural environment. It presents a number of ways and means of improving the management of national and international affairs involving fresh water. It highlights the importance of fresh water as a major issue for the environment and for development.

Water scarcity is an increasing problem in many parts of the world, yet conventional supply-side economics and management are insufficient to deal with it. One of the key water management options for water demand is water trading. This book explores the role of water trading, as an instrument of integrated water resources management.

How is water scarcity becoming a serious problem worldwide—including in the United States? This book provides a broad overview of water, sanitation, and hygiene problems faced by both developing and developed nations around the globe and suggests how these problems can be solved by imaginative and innovative thinking. Human society depends on sufficient clean water. In many parts of the world, however, this most basic commodity is in very short supply. Even in developed, first-world nations, climate change and other factors have begun to create alarming water supply issues. The Global Water Crisis: A Reference Handbook provides a detailed overview of this important topic, enabling readers to understand the nature of the world's water, sanitation, and hygiene (WASH) problems and to know what resources are best for conducting their own research on the topic. The first chapter of the book provides the historical background information pertaining to the world's water and sanitation problems; the second chapter documents the problems, explores the issues, and presents potential solutions for understanding the nature of WASH issues. The other sections provide the needed resources for readers to study the issue of the global water crisis further: perspective essays, primary documents, biographical profiles, data and documents, an extended annotated bibliography, a chronology, and a glossary.

This is a Festschrift in honour of Professor Asit K. Biswas, for his manifold contributions to water resources policy and management and his extensive efforts over six decades to generate, synthetize, apply, and disseminate knowledge at national and global levels. Global Water Resources: Festschrift in Honour of Asit K. Biswas includes invited contributions on global water issues from 23 globally renowned leaders in the public and private sectors, as well as academia, who have made significant contributions to the field of water resources policy, management, development and governance. The vision and expertise of this distinguished group of experts provides a unique focus on unfolding water issues and their bearing on world development This book will be of great value to scholars, students, and policymakers interested in water resource governance, sustainable development, and climate change. The chapters in this book were originally published as a special issue of the International Journal of Water Resources Development.

The Global Water System in the Anthropocene provides the platform to present global and regional perspectives of world-wide experiences on the responses of water management to global change in order to address issues such as variability in supply, increasing demands for water, environmental flows and land use change. It helps to build links between science and policy and practice in the area of water resources management and governance, relates institutional and technological innovations and identifies in which ways research can assist policy and practice in the field of sustainable freshwater management. Until the industrial revolution, human beings and their activities played an insignificant role influencing the dynamics of the Earth system, the sum of our planet‘s interacting physical, chemical, and biological processes. Today, humankind even exceeds nature in terms of changing the biosphere and affecting all other facets of Earth system functioning. A growing number of scientists argue that humanity has entered a new geological epoch that needs a corresponding name: the Anthropocene. Human activities impact the global water system as part of the Earth system and change the way water moves around the globe like never before. Thus, managing freshwater use wisely in the planetary water cycle has become a key challenge to reach global environmental sustainability.

In this concise introduction to water resources, Shimon Anisfeld explores the fundamental interactions between humans and water, including drinking, sanitation, irrigation, and power production. The book familiarizes students with the current water crisis and with approaches for managing this essential resource more effectively in a time of rapid environmental and social change. Anisfeld addresses both human and ecological problems, including scarcity, pollution, disease, flooding, conflicts over water, and degradation of aquatic ecosystems. In addition to providing the background necessary to understand each of these problems, the book discusses ways to move towards better management and addresses the key current debates in the water policy field. In the past, water development has often proceeded in a single-sector fashion, with each group of users implementing its own plans without coordination with other groups, resulting in both conflict and inefficiency. Now, Anisfeld writes, the challenge of water management is figuring out how to balance all the different demands for water, from sanitation to energy generation to ecosystem protection. For inquiring students of any level, Water Resources provides a comprehensive one-volume guide to a complex but vital field of study.

How much water does the world need to support growing human populations? What factors influence water quality, droughts, floods, and waterborne diseases? What are the potential effects of climate change on the world's water resources? These questions and more are discussed in this thorough introduction to the complex world of water resources. The strength of the book is its coverage of the fundamentals of the science of water, aquatic ecology, geomorphology and hydrology, supplemented by internet resources and examples from water resource issues in the news to engage the student. The book begins with a short history of human use and influence on water, followed by chapters on the geomorphology, hydrology, chemistry, and biology of lakes, rivers, and wetlands. Major disease issues, worldwide water quality and quantity problems, and potential solutions are addressed. Water laws, water allocation, and the conflicts involved are discussed using US and international examples. Students in departments of environmental studies, life science, Earth science, and engineering will benefit from this broad survey of these crucial issues.

The United Nations World Water Development Report, published every three years, is a comprehensive review providing an authoritative picture of the state of the world's freshwater resources. It offers best practices as well as in-depth theoretical analyses to help stimulate ideas and actions for better stewardship in the water sector. It is the only report of its kind, resulting from the collaboration and contributions of the 26 UN agencies, commissions, program, funds, secretariats and conventions that have a significant role in addressing global water concerns.The news media are full of talk of crises - in climate change, energy and food and troubled financial markets. These crises are linked to each other and to water resources management. Unresolved, they may lead to increasing political insecurity and conflict.Water is required to meet our fundamental needs and rising living standards and to sustain our planets fragile ecosystems. Pressures on the resource come from a growing and mobile population, social and cultural change, economic development and technological change. Adding complexity and risk is climate change, with impacts on the resource as well as on the sources of pressure on water.The challenges, though substantial, are not insurmountable. The Report shows how some countries have responded. Progress in providing drinking water is heartening, with the Millennium Development Goal target on track in most regions. But other areas remain unaddressed, and after decades of inaction, the problems in water systems are enormous and will worsen if left unattended.Leaders in the water sector can inform decisions outside their domain and manage water resources to achieve agreed socioeconomic objectives and environmental integrity. Leaders in government, the private sector and civil society determine these objectives and allocate human and financial resources to meet them. Recognizing this responsibility, they must act now!Two volume set: 336 + 96 pages (case studies). Includes CD-ROM.Published jointly with UNESCO Publishing.
