This Book includes selected papers that has been published in the Water journal Special Issue (SI) on Water Supply and Water Scarcity. Moreover, an overview of the SI is included. The papers selected for publication in the SI include review and research papers on water history, on water management issues under water scarcity regimes, on rainwater harvesting, on water quality and degradation, and on climatic variability impacts on water resources. Overall, the issue identify and highlight the main challenges in water sector, and particularly in management and protection of water resources and in use of alternative (non-conventional) water resources, especially in areas with demographic change and climate vulnerability in order to achieve sustainable and secure water supply. Furthermore, general guidelines and possible solutions for an improved and sophisticated water management system are proposed and discussed, such as the adoption of advanced technological solutions and practices that improve water-use efficiency and the use of alternative water resources, to address the growing environmental and health issues and to reduce the emerging conflicts among water users.

It is zero hour for a new US water policy! At a time when many countries are adopting new national approaches to water management, the United States still has no cohesive federal policy, and water-related authorities are dispersed across more than 30 agencies. Here, at last, is a vision for what we as a nation need to do to manage our most vital resource. In this book, leading thinkers at world-class water research institution the Pacific Institute present clear and readable analysis and recommendations for a new federal water policy to confront our national and global challenges at a critical time. What exactly is at stake? In the 21st century, pressures on water resources in the United States are growing and conflicts among water users are worsening. Communities continue to struggle to meet water quality standards and to ensure that safe drinking water is available for all. And new challenges are arising as climate change and extreme events worsen, new water quality threats materialize, and financial constraints grow. Yet the United States has not stepped up with adequate leadership to address these problems. The inability of national policymakers to safeguard our water makes the United States increasingly vulnerable to serious disruptions of something most of us take for granted: affordable, reliable, and safe water. This book provides an independent assessment of water issues and water management in the United States, addressing emerging and persistent water challenges from the perspectives of science, public policy, environmental justice, economics, and law. With fascinating case studies and first-person accounts of what helps and hinders good water management, this is a clear-eyed look at what we need for a 21st century U.S. water policy.

An objective look at America's rapidly shrinking water supply Once believed to be a problem limited to America's southwest, water shortages are now an issue coast to coast, from New England to California. In Aqua Shock: The Water Crisis in America, author Susan J. Marks provides a comprehensive analysis of the current conflicts being waged over dwindling water supplies. She presents the findings of university studies, think tanks, and research groups, as well as the opinions of water experts, including Peter Gleick, president of the Pacific Institute for Studies in Development, Environment, and Security. The book Explains where our water comes from and who controls it, as well as the cost of water on cash, commodities, and capitalism Describes the risks of running out of water Details how we can preserve and protect our most precious, yet most undervalued natural resource Right now, battles over water supplies rage across the country. Aqua Shock is an objective look at how we arrived at this crisis point and what we can do-and should be doing-to solve the water crisis in America.
