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.

Daniel McCool not only chronicles the history of water development agencies in America and the way in which special interests have abused rather than preserved the country’s rivers, he also narrates the second, brighter act in this ongoing story: the surging, grassroots movement to bring these rivers back to life and ensure they remain pristine for future generations. The culmination of ten years of research and observation, McCool’s book confirms the surprising news that America’s rivers are indeed returning to a healthier, free-flowing condition. The politics of river restoration demonstrates how strong grassroots movements can challenge entrenched powers and win. Through passion and dedication, ordinary people are reclaiming the American landscape, forming a “river republic” of concerned citizens from all backgrounds and sectors of society. As McCool shows, the history, culture, and fate of America is tied to its rivers, and their restoration is a microcosm mirroring American beliefs, livelihoods, and an increasing awareness of what two hundred years of environmental degradation can do. McCool profiles the individuals he calls “instigators,” who initiated the fight for these waterways and, despite enormous odds, have succeeded in the near-impossible task of challenging and changing the status quo. Part I of the volume recounts the history of America’s relationship to its rivers; part II describes how and why Americans “parted” them out, destroying their essence and diminishing their value; and part III shows how society can live in harmony with its waterways while restoring their well-being—and, by extension, the well-being of those who depend on them.

Water is newsworthy: there is, or will be, a world water crisis. Aggravated by climate change, we are approaching the limits of human exploitation of freshwater resources, notably in growing essential food. The complexities and uncertainties associated with improving our management of fresh water take the potential remedies out of the hands of simple, local, hard engineering and into much larger units – the basin, the ecosystem and the global context, and also require longer term perspectives. The Third Edition follows the same structure as its predecessors, presenting the historical and scientific backgrounds to land-water interactions and establishing the links with development processes and policies. Throughout, its two major messages are that our new philosophy should be one of ‘humans in the ecosystem’ and that the guidance from science, being uncertain and contested, must be operationalized in a participatory system of governance based on participation. Following a review of progress towards these elements in the developed world, the international case studies update the situation in the developing world following the Millennium Development Goals, our new emphasis on poverty and on global food supplies. This book covers the multitude of scientific research findings, development of ‘tools’ and spatial/temporal scale challenges which have emerged in the last decade. Tensions are highlighted in the current and future role of large dams, country studies are retained (and considerably updated) and development contexts are explored in greater depth as a dividing line in capacity to cope with land and water stress. "Technical issues" have been expanded to cover major droughts, environmental flows and the restoration of rivers and wetlands. A separate chapter picks up these themes under terms of their relationship with uncertainty and the widespread perception that a new ethos of adaptive management is needed in the water sector. For students of geography, environmental science, hydrology, and development studies this innovative edition provides a reasoned, academic basis of evidence for sustainable, adaptive management of rivers and related large-scale ecosystems using more than 600 new sources. It will also prove invaluable for lecturers and practitioners.

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.

Enlarged, enhanced and internationalized edition of the first restoration ecology textbook to be published, with foreword by Dr. Steven Whisnant of Texas A&M University and Chair of the Society of Ecological Restoration. Since 2006, when the first edition of this book appeared, major advances have taken place in restoration science and in the practice of ecological restoration. Both are now accepted as key components of the increasingly urgent search for sustainability at global, national, and community levels – hence the phrase 'New Frontier' in the title. While the first edition focused on ecosystems and landscapes in Europe, this new edition covers biomes and contexts all over the world. Several new chapters deal with broad issues such as biological invasions, climate change, and agricultural land abandonment as they relate to restoration science and ecological restoration. Case studies are included from Australia, North America, and the tropics. This is an accessible textbook for senior undergraduate and graduate level students, and early career scientists. The book also provides a solid scientific background for managers, volunteers, and mid-career professionals involved in the practice of ecological restoration. Review of the first edition: "I suspect that this volume will find its way onto the shelves of many restoration researchers and practitioners and will be used as a key text in graduate courses, where it will help fill a large void. My own copy is already heavily bookmarked, and will be a constant source of research ideas and lecture material."

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.
