This beautifully written and deeply personal collection of essays paints a progressive view of the American West as seen by a geologist. Ellen Wohl traces her twenty years of living and conducting research in the natural landscapes of the West as she investigates the conflict between environmental history and widely held romanticized views of the region. Wohl grew up in Ohio, subscribing to a common perception of the American West as an unchanged frontier. Moving to Arizona, she became enthralled with how the landscapes and ecosystems of the West have undergone change, both through geologic time and during the historical era of European settlement. These essays tell of her early training as a geomorphologist and provide a memorable account of her research in the rivers of the West. As the lessons accrue, Wohl gives us the benefit of her experience and shows how years of studying and living in the Colorado Rockies have enhanced her understanding of landscape change through time. Building on the literary tradition of Joseph Wood Krutch, Terry Tempest Williams, and John McPhee, Wohl provides an up-to-date portrait of the West and brings a new urgency to the call for conservation of the region's land, water, and resources.

In The Big Muddy, the first long-term environmental history of the Mississippi, Christopher Morris offers a brilliant tour across five centuries as he illuminates the interaction between people and the landscape, from early hunter-gatherer bands to present-day industrial and post-industrial society. Morris shows that when Hernando de Soto arrived at the lower Mississippi Valley, he found an incredibly vast wetland, forty thousand square miles of some of the richest, wettest land in North America, deposited there by the big muddy river that ran through it. But since then much has changed, for the river and for the surrounding valley. Indeed, by the 1890s, the valley was rapidly drying. Morris shows how centuries of increasingly intensified human meddling--including deforestation, swamp drainage, and levee construction--led to drought, disease, and severe flooding. He outlines the damage done by the introduction of foreign species, such as the Argentine nutria, which escaped into the wild and are now busy eating up Louisiana's wetlands. And he critiques the most monumental change in the lower Mississippi Valley--the reconstruction of the river itself, largely under the direction of the Army Corps of Engineers. Valley residents have been paying the price for these human interventions, most visibly with the disaster that followed Hurricane Katrina. Morris also describes how valley residents have been struggling to reinvigorate the valley environment in recent years--such as with the burgeoning catfish and crawfish industries--so that they may once again live off its natural abundance. Morris concludes that the problem with Katrina is the problem with the Amazon Rainforest, drought and famine in Africa, and fires and mudslides in California--it is the end result of the ill-considered bending of natural environments to human purposes.

Rivers in the Landscape: Science and Management offers a comprehensive and accessible overview of the current state of knowledge for river process and form, taking a holistic approach to the subject with coverage of integrated river science and management in practice. The processes and forms present in channelized surface flow–rivers–are systematically explored in this book to • emphasize the connectivity between rivers and the greater landscape by explicitly considering the interactions between rivers and tectonics, climate, biota, and human activities; • provide a concise summary of the current state of knowledge for physical process and form in rivers; • reflect the diversity of river environments, from mountainous, headwater channels to large, lowland, floodplain rivers and from the arctic to the tropics; • reflect the diverse methods that scientists use to characterize and understand river process and form, including remote sensing, field measurements, physical experiments, and numerical simulations; • reflect the increasing emphasis on quantification in fluvial geomorphology and the study of Earth surfaces in general; • provide both an introduction to the classic, foundational papers on each topic, and a guide to the latest, particularly insightful and integrative references. Aimed at advanced undergraduate students, graduate students, and professionals looking for a concise summary of physical aspects of rivers, this book emphasizes general principles and conceptual models, as well as concrete examples of each topic drawn from the extensive literature on river process and form.

Across much of the industrialized world, rivers that were physically transformed and ecologically ruined to facilitate industrial and agricultural development are now the focus of restoration and rehabilitation efforts. River Futures discusses the emergence of this new era of river repair and documents a comprehensive biophysical framework for river science and management. The book considers what can be done to maximize prospects for improving river health while maintaining or enhancing the provision of ecosystem services over the next fifty to one-hundred years. It provides a holistic overview of considerations that underpin the use of science in river management, emphasizing cross-disciplinary understanding that builds on a landscape template. The book frames the development of integrative river science and its application to river rehabilitation programs develops a coherent set of guiding principles with which to approach integrative river science considers the application of cross-disciplinary thinking in river rehabilitation experiences from around the world examines the crossover between science and management, outlining issues that must be addressed to promote healthier river futures Case studies explore practical applications in different parts of the world, highlighting approaches to the use of integrative river science, measures of success, and steps that could be taken to improve performance in future efforts. River Futures offers a positive, practical, and constructive focus that directly addresses the major challenge of a new era of river conservation and rehabilitation—that of bringing together the diverse and typically discipline-bound sets of knowledge and practices that are involved in repairing rivers. It is a valuable resource for anyone involved in river restoration and management, including restorationists, scientists, managers, and policymakers, as well as undergraduate and graduate students.

Water has long been the object of political ambition and conflict. Recent history is full of leaders who tried to harness water to realize national dreams. Yet the people who most need water--farmers, rural villages, impoverished communities--are too often left, paradoxically, with desiccated fields, unfulfilled promises, and refugee status. It doesn't have to be this way, according to Fred Pearce. A veteran science news correspondent, Pearce has for over fifteen years chronicled the development of large-scale water projects like China's vast Three Gorges dam and India's Sardar Sarovar. But, as he and numerous other authors have pointed out, far from solving our water problems, these industrial scale projects, and others now in the planning, are bringing us to the brink of a global water crisis. Pearce decided there had to be a better way. To find it, he traveled the globe in search of alternatives to mega-engineering projects. In Keepers of the Spring, he brings back intriguing stories from people like Yannis Mitsis, an ethnic Greek Cypriot, who is the last in his line to know the ways and whereabouts of a network of underground tunnels that have for centuries delivered to farming communities the water they need to survive on an arid landscape. He recounts the inspiring experiences of small-scale water stewards like Kenyan Jane Ngei, who reclaimed for her people a land abandoned by her government as a wasteland. And he tells of many others who are developing new techniques and rediscovering ancient ones to capture water for themselves. The solution to our water problems, he finds, may not lie in new technologies but in recovering ancient traditions, using water more efficiently, and better understanding local hydrology. Are these approaches adequate to serve the world's growing populations? The answer remains unclear. But we ignore them at our own peril.
