Book Description
In this groundbreaking book, veteran science correspondent Fred Pearce travels to more than thirty countries to examine the current state of crucial water sources. Deftly weaving together the complicated scientific, economic, and historic dimensions of the world water crisis, he provides our most complete portrait yet of this growing danger and its ramifications for us all. "A strong-and scary-case that a worldwide water shortage is the most fearful looming environmental crisis. With a drumbeat of facts both horrific (thousands of wells in India and Bangladesh are poisoned by fluoride and arsenic) and fascinating (it takes 20 tons of water to make one pound of coffee), the former New Scientist news editor documents a "kind of cataclysm" already affecting many of the world"s great rivers." -Publishers Weekly, starred review "Oil we can replace. Water we can"t-which is why this book is both so ominous and so important." -Bill McKibben, author of The End of Nature

Book Description
Large Rivers: Geomorphology and Management explores an important topic in geomorphology and sedimentology: the form and function of major rivers. Our knowledge of the big rivers of the world is limited. It is currently difficult to recognise large rivers of the past from relict sedimentary deposits or to structure management policies for long international rivers. This exciting book brings together a set of papers on large rivers of the world, as a unique introduction to a demanding subject. The book includes thirty chapters and is organised into three sections. The first part is on the environmental requirements for creating and maintaining a major river system. The second is a collection of case studies on 14 large rivers from different continents, covering a range of physical environments. The third section includes chapters on the measurement and management of large rivers. First book to offer in a single volume state-of-the-art knowledge on management and geomorphology of large rivers of the world A pioneering study, pushing the boundaries of our knowledge related to big rivers Includes comprehensive case studies covering the major large rivers of the world including Amazon, Mississippi, Nile, Congo, Indus, and Mekong Written by a leading team of distinguished, international contributors Large Rivers: Geomorphology and Management is essential reading for postgraduate students and researchers in fluvial geomorphology, hydrology, sedimentary geology, and river management. It is also of relevance to engineers and environmental consultants in the private and public sectors working on major rivers of the world.

Book Description
The conventional approach to river protection has focused on water quality and maintaining some "minimum" flow that was thought necessary to ensure the viability of a river. In recent years, however, scientific research has underscored the idea that the ecological health of a river system depends not on a minimum amount of water at any one time but on the naturally variable quantity and timing of flows throughout the year. In Rivers for Life, leading water experts Sandra Postel and Brian Richter explain why restoring and preserving more natural river flows are key to sustaining freshwater biodiversity and healthy river systems, and describe innovative policies, scientific approaches, and management reforms for achieving those goals. Sandra Postel and Brian Richter: explain the value of healthy rivers to human and ecosystem health; describe the ecological processes that support river ecosystems and how they have been disrupted by dams, diversions, and other alterations; consider the scientific basis for determining how much water a river needs; examine new management paradigms focused on restoring flow patterns and sustaining ecological health; assess the policy options available for managing rivers and other freshwater systems; explore building blocks for better river governance. Sandra Postel and Brian Richter offer case studies of river management from the United States (the San Pedro, Green, and Missouri), Australia (the Brisbane), and South Africa (the Sabie), along with numerous examples of new and innovative policy approaches that are being implemented in those and other countries. Rivers for Life presents a global perspective on the challenges of managing water for people and nature, with a concise yet comprehensive overview of the relevant science, policy, and management issues. It presents exciting and inspirational information for anyone concerned with water policy, planning and management, river conservation, freshwater biodiversity, or related topics.

Book Description
"Fundamentally, the salmon's decline has been the consequence of a vision based on flawed assumptions and unchallenged myths.... We assumed we could control the biological productivity of salmon and 'improve' upon natural processes that we didn't even try to understand. We assumed we could have salmon without rivers." --from the introduction From a mountain top where an eagle carries a salmon carcass to feed its young to the distant oceanic waters of the California current and the Alaskan Gyre, salmon have penetrated the Northwest to an extent unmatched by any other animal. Since the turn of the twentieth century, the natural productivity of salmon in Oregon, Washington, California, and Idaho has declined by eighty percent. The decline of Pacific salmon to the brink of extinction is a clear sign of serious problems in the region. In Salmon Without Rivers, fisheries biologist Jim Lichatowich offers an eye-opening look at the roots and evolution of the salmon crisis in the Pacific Northwest. He describes the multitude of factors over the past century and a half that have led to the salmon's decline, and examines in depth the abject failure of restoration efforts that have focused almost exclusively on hatcheries to return salmon stocks to healthy levels without addressing the underlying causes of the decline. The book: describes the evolutionary history of the salmon along with the geologic history of the Pacific Northwest over the past 40 million years considers the indigenous cultures of the region, and the emergence of salmon-based economies that survived for thousands of years examines the rapid transformation of the region following the arrival of Europeans presents the history of efforts to protect and restore the salmon offers a critical assessment of why restoration efforts have failed Throughout, Lichatowich argues that the dominant worldview of our society -- a worldview that denies connections between humans and the natural world -- has created the conflict and controversy that characterize the recent history of salmon; unless that worldview is challenged and changed, there is little hope for recovery. Salmon Without Rivers exposes the myths that have guided recent human-salmon interactions. It clearly explains the difficult choices facing the citizens of the region, and provides unique insight into one of the most tragic chapters in our nation's environmental history.

Book Description
Urban Rivers examines urban interventions on rivers through politics, economics, sanitation systems, technology, and societies; how rivers affected urbanization spatially, in infrastructure, territorial disputes, and in flood plains, and via their changing ecologies. Providing case studies from Vienna to Manitoba, the chapters assemble geographers and historians in a comparative survey of how cities and rivers interact from the seventeenth century to the present. Rising cities and industries were great agents of social and ecological changes, particularly during the nineteenth century, when mass populations and their effluents were introduced to river environments. Accumulated pollution and disease mandated the transfer of wastes away from population centers. In many cases, potable water for cities now had to be drawn from distant sites. These developments required significant infrastructural improvements, creating social conflicts over land jurisdiction and affecting the lives and livelihood of nonurban populations. The effective reach of cities extended and urban space was remade. By the mid-twentieth century, new technologies and specialists emerged to combat the effects of industrialization. Gradually, the health of urban rivers improved. From protoindustrial fisheries, mills, and transportation networks, through industrial hydroelectric plants and sewage systems, to postindustrial reclamation and recreational use, Urban Rivers documents how Western societies dealt with the needs of mass populations while maintaining the viability of their natural resources. The lessons drawn from this study will be particularly relevant to today's emerging urban economies situated along rivers and waterways.

Book Description
The American West, blessed with an abundance of earth and sky but cursed with a scarcity of life's most fundamental need, has long dreamed of harnessing all its rivers to produce unlimited wealth and power. In Rivers of Empire, award-winning historian Donald Worster tells the story of this dream and its outcome. He shows how, beginning in the mid-nineteenth century, Mormons were the first attempting to make that dream a reality, damming and diverting rivers to irrigate their land. He follows this intriguing history through the 1930s, when the federal government built hundreds of dams on every major western river, thereby laying the foundation for the cities and farms, money and power of today's West. Yet while these cities have become paradigms of modern American urban centers, and the farms successful high-tech enterprises, Worster reminds us that the costs have been extremely high. Along with the wealth has come massive ecological damage, a redistribution of power to bureaucratic and economic elites, and a class conflict still on the upswing. As a result, the future of this "hydraulic West" is increasingly uncertain, as water continues to be a scarce resource, inadequate to the demand, and declining in quality.
