Book Description
It is not the purpose of this work to propose a specific format for the settlement of the city's current difficulties with the valley, to resolve the environmental questions associated with Los Angeles's proposed groundwater pumping program, or to promote any cause associated with the developing situation in the Owens Valley. But by performing the essential historical task of separating what happened from what did not, and by distinguishing in this way the choices which have been made from those which have yet to be decided, it is my hope that this effort will help to establish that common basis for understanding which is essential for the debate over specific issues to proceed most effectively. This book, then, is scarcely the last word on the Owens Valley conflict: the final chapter, after all, has yet to be written. The story that has emerged here is at once very different and more troubling than the conventional treatments of the conflict as a simplistic political morality play. Any attempt to deal with so controversial a subject, however, is almost certain to spark controversy itself. For that reason, with the exception of a small collection of private letters, this work is constructed entirely from the published documents and other materials available to the general public, anchoring the narrative in sources the reader can consult to trace the line of my argument on any point with which he or she may disagree. In addition, the work as a whole has been reviewed for technical accuracy by officials of the Los Angeles Department of Water and Power, although the department is in no way responsible for the content of this study or the conclusions drawn from it.

Book Description
Far more than oil, the control of water wealth throughout history has been pivotal to the rise and fall of great powers, the achievements of civilization, the transformations of society's vital habitats, and the quality of ordinary daily lives. Today, freshwater scarcity is one of the twenty-first century's decisive, looming challenges, driving new political, economic, and environmental realities across the globe. In Water, Steven Solomon offers the first-ever narrative portrait of the power struggles, personalities, and breakthroughs that have shaped humanity from antiquity's earliest civilizations through the steam-powered Industrial Revolution and America's century. Meticulously researched and masterfully written, Water is a groundbreaking account of man's most critical resource in shaping human destinies, from ancient times to our dawning age of water scarcity.

Book Description
For centuries, falling water has been used in parts of the world to create energy to run grinding stones at mills and irrigation systems for crops. This interesting book shows how the use of this "clean" form of energy, called hydroelectricity, is being expanded to help us build a more sustainable future. Discover how other forms of water-based energy, such as energy from ocean waves and tides, are being harnessed and used to help create electricity to power our homes, offices, and factories.

Book Description
"If the wars of the last century were fought over oil, the wars of this century will be fought over water." -Ismail Serageldin, The World Bank The giant dams of today are the modern Pyramids, colossally expensive edifices that generate monumental amounts of electricity, irrigated water, and environmental and social disaster. With Deep Water, Jacques Leslie offers a searching account of the current crisis over dams and the world's water. An emerging master of long-form reportage, Leslie makes the crisis vivid through the stories of three distinctive figures: Medha Patkar, an Indian activist who opposes a dam that will displace thousands of people in western India; Thayer Scudder, an American anthropologist who studies the effects of giant dams on the peoples of southern Africa; and Don Blackmore, an Australian water manager who struggles to reverse the effects of drought so as to allow Australia to continue its march to California-like prosperity. Taking the reader to the sites of controversial dams, Leslie shows why dams are at once the hope of developing nations and a blight on their people and landscape. Deep Water is an incisive, beautifully written, and deeply disquieting report on a conflict that threatens to divide the world in the coming years.
