"This thought-provoking book demonstrates how processes of landscape transformation, usually illustrated only in simplified or idealized form, play out over time in real, complex landscapes. Trimble illustrates how a simple landscape disturbance, generated in this case by agriculture, can spread an astonishing variety of altered hydrologic and sedimentation processes throughout a drainage basin. The changes have spatial and temporal patterns forced on them by the distinctive topographic structure of drainage basins. "Through painstaking field surveys, comparative photographic records, careful dating, a skillful eye for subtle landscape features, and a geographer’s interdisciplinary understanding of landscape processes, the author leads the reader through the arc of an instructive and encouraging story. Farmers—whose unfamiliarity with new environmental conditions led initially to landscape destruction, impoverishment, and instability—eventually adapted their land use and settlement practices and, supported by government institutions, recovered and enriched the same working landscape. "For the natural scientist, Historical Agriculture and Soil Erosion in the Upper Mississippi Valley Hill Country illustrates how an initially simple alteration of land cover can set off a train of unanticipated changes to runoff, erosion, and sedimentation processes that spread through a landscape over decades—impoverishing downstream landscapes and communities. Distinct zones of the landscape respond differently and in sequence. The effects take a surprisingly long time to spread through a landscape because sediment moves short distances during storms and can persist for decades or centuries in relatively stable forms where it resists further movement because of consolidation, plant reinforcement, and low gradients. "For the social scientist, the book raises questions of whether and how people can be alerted early to their potential for environmental disturbance, but also for learning and adopting restorative practices. Trimble’s commitment to all aspects of this problem should energize both groups." —Professor Thomas Dunne, Bren School of Environmental Science and Management, UC Santa Barbara

A brand new edition of the definitive textbook on humankind’s impact on the Earth’s environment—now in full color This classic text explores the multitude of impacts that humans have had over time upon vegetation, animals, soils, water, landforms, and the atmosphere. It considers the ways in which climate changes and modifications in land cover may change the environment in coming decades. Thoroughly revised to cover the remarkable transformation in interest that humans are having in the environment, this book examines previously uncovered topics, such as rewilding, ecosystem services, techniques for study, novel and no analogue ecosystems, and more. It also presents the latest views on big themes such as human origins, the anthropocene, domestication, extinctions, and ecological invasions. Extensively re-written, Human Impact on the Natural Environment, Eighth Edition contains many new and updated statistical tables, figures, and references. It offers enlightening chapters that look at the past and present state of the world—examining our impact on the land itself and the creatures that inhabit it; the oceans, lakes, rivers and streams; and the climate and atmosphere. The book also takes a deep look at our future impact on the planet and its resources—our affect on the coastal environments, the cryosphere and the drylands, as well as the hydrological and geomorphological impacts. Fully updated to take account of recent advances in our understanding of global warming and other phenomena Offers current opinions on such topics as human origins, the anthropocene, domestication, extinctions, and ecological invasions Features a full-color presentation to allow for more and clearer photographs and diagrams Contains more international case studies than previous editions to balance UK examples Human Impact on the Natural Environment is essential reading for undergraduates in geography and environmental science, and for those who want a thorough, wide-ranging and balanced overview of the impacts of humans upon natural processes and systems from the Stone Age to the Anthropocene and who wish to understand the major environmental issues that concern the human race at the present time.

In the twentieth century, natural resource conservation emerged as a vital force in US politics, laying the groundwork for present-day sustainability. Merging environmental, agricultural, and political history, Joshua Nygren examines the political economy and ecology of agricultural conservation through the lens of the "conservation-industrial complex." This evolving public-private network—which united the US Department of Agriculture, Congress, local and national organizations, and the agricultural industry—guided soil and water conservation in rural America for much of the century. Contrary to the classic tales of US environmental politics and the rise and fall of the New Deal Order, this book emphasizes continuity. Nygren demonstrates how the conservation policies, programs, and partnerships of the 1930s and 1940s persisted through the age of environmentalism, and how their defining traits anticipated those typically associated with late twentieth-century political culture. The conservation-industrial complex promoted a development-oriented brand of conservation that aided the rise of large-scale, capital-intensive agriculture which continues today. It also reshaped the physical and political landscapes of the country, leading to impressive conservation victories and spectacular failures by privileging some environments, degrading others, and intensifying farm depopulation. In the name of environmental protection, agricultural conservation made rural America less equal.

Providence Canyon State Park, also known as Georgia’s “Little Grand Canyon,” preserves a network of massive erosion gullies allegedly caused by poor farming practices during the nineteenth century. It is a park that protects the scenic results of an environmental disaster. While little known today, Providence Canyon enjoyed a modicum of fame in the 1930s. During that decade, local boosters attempted to have Providence Canyon protected as a national park, insisting that it was natural. At the same time, national and international soil experts and other environmental reformers used Providence Canyon as the apotheosis of human, and particularly southern, land abuse. Let Us Now Praise Famous Gullies uses the unlikely story of Providence Canyon—and the 1930s contest over its origins and meaning—to recount the larger history of dramatic human-induced soil erosion across the South and to highlight the role that the region and its erosive agricultural history played in the rise of soil science and soil conservation in America. More than that, though, the book is a meditation on the ways in which our persistent mental habit of separating nature from culture has stunted our ability to appreciate places like Providence Canyon and to understand the larger history of American conservation.

A comprehensive treatment of the human role in modifying geomorphological forms and processes and their influence on the Earth's systems.

The late Professor Reds Wolman in his Foreword to the award-winning second edition said, "This is not your ordinary textbook. Environmental Hydrology is indeed a textbook, but five elements often found separately combine here in one text to make it different. It is eclectic, practical, in places a handbook, a guide to fieldwork, engagingly personal

The hidden history of an economic and cultural catastrophe that is threatening our very food supply—the disappearance of the American farmer. Taking on this story of heart and hardship, award-winning writer Brian Reisinger weaves forgotten eras of American history with his own family’s four-generation fight for survival in Midwestern farm country. Readers learn the truth about America’s most detrimental and unexplained socioeconomic crisis: How the family farms that feed us went from cutting a middle-class path through the Great Depression to barely making ends meet in modern America. Along the way, they’ll see what it truly takes to feed our country: accidents that can kill or maim; weather that blesses or threatens; resilience in the face of crushing economic crises, from inflation to COVID-19; and the tradition that presses down on each generation when you're not just fighting for your job, you're fighting for your heritage. With newly analyzed data, sharp historical analysis, conversations with some of modern farming’s most notable champions and critics alike, honest debate, and personal storytelling, Reisinger reveals the roots of a problem with stakes as high as they come. A vulnerable food supply chain, soaring prices for American families, environmental and ecological dilemmas, the security of our farmland from foreign adversaries, farmer suicides, addictions, a deepening urban-rural divide, and more worries than ever about what’s for dinner. These are all becoming the hallmarks of a food system that has long stood as a modern miracle. Land Rich, Cash Poor offers the honest truth about these issues, and a candid look at what we can do about them—before it’s too late.

Pressure on large fluvial lowlands has increased tremendously during the past twenty years because of flood control, urbanization, and increased dependence upon floodplains and deltas for food production. This book examines human impacts on lowland rivers, and discusses how these changes affect different types of riverine environments and flood processes. Surveying a global range of large rivers, it provides a primary focus on the lower Rhine River in the Netherlands and the Lower Mississippi River in Louisiana. A particular focus of the book is on geo-engineering, which is described in a straight-forward writing style that is accessible to a broad audience of advanced students, researchers, and practitioners in global environmental change, fluvial geomorphology and sedimentology, and flood and water management.

Whether referring to a place, a nonhuman animal or plant, or a state of mind, wild indicates autonomy and agency, a will to be, a unique expression of life. Yet two contrasting ideas about wild nature permeate contemporary discussions: either that nature is most wild in the absence of a defiling human presence, or that nature is completely humanized and nothing is truly wild. This book charts a different path. Exploring how people can become attuned to the wild community of life and also contribute to the well-being of the wild places in which we live, work, and play, Wildness brings together esteemed authors from a variety of landscapes, cultures, and backgrounds to share their stories about the interdependence of everyday human lifeways and wildness. As they show, far from being an all or nothing proposition, wildness exists in variations and degrees that range from cultivated soils to multigenerational forests to sunflowers pushing through cracks in a city alley. Spanning diverse geographies, these essays celebrate the continuum of wildness, revealing the many ways in which human communities can nurture, adapt to, and thrive alongside their wild nonhuman kin. From the contoured lands of Wisconsin’s Driftless region to remote Alaska, from the amazing adaptations of animals and plants living in the concrete jungle to indigenous lands and harvest ceremonies, from backyards to reclaimed urban industrial sites, from microcosms to bioregions and atmospheres, manifestations of wildness are everywhere. With this book, we gain insight into what wildness is and could be, as well as how it might be recovered in our lives—and with it, how we might unearth a more profound, wilder understanding of what it means to be human. Wildness: Relations of People and Place is published in association with the Center for Humans and Nature, an organization that brings together some of the brightest minds to explore and promote human responsibilities to each other and the whole community of life.
