DOWNLOAD EBOOKHave agricultural management efforts begun in the desperation of the Dust Bowl brought us to where we need to be tomorrow? Questions about the environmental footprint of farming make this book required reading. Approximately 62% of the total U.S. land area is used for agriculture, and this land also provides critical ecosystem functions. Authors from each region of the continental United States describe the progress of soil and water conservation to date and visualize how agricultural production practices must change in future years to address the newest challenges.

DOWNLOAD EBOOKOnce the grain basket for South Africa, much of Lesotho has become a scarred and treeless wasteland. The nation's spectacular gullying has concerned environmentalists and conservationists for more than half a century, In Imperial Gullies: Soil Erosion and Conservation in Lesotho, Kate B. Showers documents the truth behind this devastation. Showers reconstructs the history of the landscape, beginning with a history of the soil. She concludes that Lesotho's distinctive erosion chasms, called dongas, often cited as an example of destructive land-use practices by African farmers, actually were caused by colonial and postcolonial practices. The residents of Lesotho emerge as victims of a failed technology. Their efforts to mitigate or resist implementation of destructive soil conservation engineering works were thwarted, and they were blamed for the consequences of policies promoted by international soil conservationists since the 1930s. Imperial Gullies calls for an observational, experimental and, most importantly, a fully consultative and participatory approach to address Lesotho's serious contemporary problems of soil erosion. The first book to bring to center stage the historical practice of colonial soil science and a cautionary tale of western science in unfamiliar terrain it will interest a broad, interdisciplinary audience in African and environmental studies, social sciences, and history. "Showers shows how local people understood that colonial contour conservation methods and road building actually stimulated gully erosion, something colonial scientists failed to realize. Overall it is undoubtedly one of the most important books written to date on any part of the environmental history of Africa. Moreover it stands out in the discipline of environmental history in general as an unusually sophisticated work of great insight and explanatory power."---Richard H. Grove, author of Green Imperialism: Colonial Expansion, Tropical Island Edens and the Origins of Environmentalism, 1600-1860 Kate B. Showers is a visiting research fellow and senior research associate at the Centre for World Environmental History, University of Sussex, England. She has lived in rural Lesotho and has served as head of research, Institute of Southern African Studies, National University of Lesotho.

DOWNLOAD EBOOKOver the past century American agriculture has shifted dramatically with small, commercial farms finding it increasingly difficult to compete with large-scale (mostly indoor) animal feeding operations (AFOs). In this book, Terence J. Centner investigates the environmental, social, economic, and political impact of the rise of the so-called factory farm, exposing the ramifications of the contemporary trend toward industrial-scale food production. Just as Rachel Carson's landmark Silent Spring used the disappearance of songbirds as a jumping-off point for a work that raised public awareness of pesticides' devastating environmental impact, Empty Pastures sees the dwindling numbers of livestock in the American countryside as a symptom of a broader transformation, one with serious consequences for the rural landscape and its inhabitants--animal as well as human. After outlining the rise of the AFO, Centner examines the troubling consequences of consolidation in animal farming and suggests a number of remedies. The issues he tackles include groundwater contamination, the loss of biodiversity, animal welfare, concentrated odors and other nuisances, soil erosion, and the economic effects of the disappearance of the small family farm. Inspired by largely abandoned traditional practices rather than a radical and unrealistic vision of a return to an idealized past, Centner proposes a series of pragmatic reforms for regulating factory farms to halt ecological degradation and revitalize rural communities.

DOWNLOAD EBOOKThis title, first published in 1951, examines the growth, fields, techniques, aims and trends of geography at the time. The book is divided into three parts, of which the first deals with the evolution of geography and its philosophical basis. The second is concerned with studies of special environments and with advances in geomorphology, meteorology, climate, soils and regionalism. The last part describes field work, sociological and urban aspects, the function of the Geographical Society and geo-pacifics. Geography in the Twentieth Century will be of interest to students of both physical and human geography.
