From cities to biofuels, competition for water is accelerating. Climate change threatens to intensify the onset and severity of the water crisis in several regions of the developing world: this is already happening throughout much of Asia, the Mediterranean, southwestern Australia, and the southwestern US. Along with water shortages, unsafe water becomes an increasingly widespread problem, too. As water crises trigger food and health crises, billions may slip further into poverty, leading to greater social and political unrest, new wars, and worsening national security. Out of Water doesn't just illuminate the coming global water crisis: it presents innovative solutions in agriculture, engineering, governance, and beyond, including state-of-the art techniques for integrated water management. This book will help raise the level of debate about water to the highest levels of government, and identify workable reforms and incentives to help water users utilize this crucial resource far more efficiently.

Water is the next oil over which nations will fight wars. Severe water shortages already affect some 450 million people living in 29 countries, and analysts have predicted that tensions over water rights in Asia, Africa, and the Middle East could explode into violent clahses and even full-blown wars if governments do not manage existing water supplies more efficiently. Worldwide, 220 river basins are shared by two or more countries and the tensions caused by water scarcity will escalate in this century---the water shortage problems will be exacerbated by global warming and its associated unpredicatable weather patterns. In 2001, the CIA predicted that by 2015, almost half of the world?s population, more than 3 billion people, will live in "water-stressed"countries. How can communities that don't have millions of dollars to hire multinational engineering companies to build highly advanced (but also highly energy and chemical intensive) water- and wastewater-treatment systems? This book is full of practical, low-cost, effective, ecological and economically sustainable, environmental friendly solutions for communities. In the 762 pages (with 185 diagrams and 910 photographs), readers will be introduced to many types of ecologically designed and engineered water- and wastewater-treatment systems, which communities can build with locally available labor, expertise, and resources.

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.

Always considered a classic renewable resource, after a hundred thousand years of farming and industry, rivers in many parts of the world are running dry and the groundwater is over pumped. In addition, the rate at which water sources are becoming contaminated with waste from humans, industry, and agriculture is truly alarming. Do these factors add up to a water crisis that merits drastic, large-scale action? Not necessarily say the editors of Water Crisis: Myth or Reality. They challenge this pessimism, concluding that while there are serious global water issues to be considered, the concept of a global water crisis is largely overstated. The book examines the issues and explores which conditions are permanent and unchangeable and which are remediable and changeable. The chapters explore when and where severe regional and local water problems occur and make suggestions about how they may be solved in a deliberate, non-crisis manner. The book covers recent breakthroughs in desalination technologies, the eco-sanitation revolution, international trade in agricultural products, methods of governance and negotiation in water allocation, and pricing and devolution of property rights and the roles they play in solving water issues. The editors, along with a panel of world-renowned experts, suggest that water issues can be solved over the next few decades using new technologies and processes.

This is the eBook version of the printed book. This Element is an excerpt from Out of Water: From Abundance to Scarcity and How to Solve the World’s Water Problems (9780131367265) by Colin Chartres and Samyuktha Varma. Available in print and digital formats. The “Blue Revolution”: how to overcome the emerging global water crisis that will lead to food crises, unrest, and uncontrolled mass migration Lack of water for growing food will be one of the 21st century’s most critical issues. If we don’t change how we manage water, the future will consist of increasingly frequent food crises, social and political unrest, and potential mass migrations out of areas most severely affected. We need to consider a “Blue Revolution.”

The Times Book of the Year pick ‘Smart, sobering, and scholarly. ’ – Steve Brusatte, the Sunday Times bestselling author of The Rise and Fall of Dinosaurs A gripping, thought-provoking and ultimately optimistic investigation into the world’s next great climate crisis – the scarcity of water. Water scarcity is the next big climate crisis. Water stress – not just scarcity, but also quality issues caused by pollution – is already driving the first waves of climate refugees. Rivers are drying out before they meet the oceans and ancient lakes are disappearing. It’s increasingly clear that human mismanagement of water is dangerously unsustainable, for both ecological and human survival. And yet in recent years some key countries have been quietly and very successfully addressing water stress. How are Singapore and Israel, for example – both severely water-stressed countries – not in the same predicament as Chennai or California? In The Last Drop, award-winning environmental journalist Tim Smedley meets experts, victims, activists and pioneers to find out how we can mend the water table that our survival depends upon. He offers a fascinating, universally relevant account of the environmental and human factors that have led us to this point, and suggests practical ways to address the crisis, before it’s too late.

A radical new approach to tackling the growing threat of water scarcity Water is essential to life, yet humankind’s relationship with water is complex. For millennia, we have perceived it as abundant and easily accessible. But water shortages are fast becoming a persistent reality for all nations, rich and poor. With demand outstripping supply, a global water crisis is imminent. In this trenchant critique of current water policies and practices, Edward Barbier argues that our water crisis is as much a failure of water management as it is a result of scarcity. Outdated governance structures and institutions, combined with continual underpricing, have perpetuated the overuse and undervaluation of water and disincentivized much-needed technological innovation. As a result “water grabbing” is on the rise, and cooperation to resolve these disputes is increasingly fraught. Barbier draws on evidence from countries across the globe to show the scale of the problem, and outlines the policy and management solutions needed to avert this crisis.
