Soils of South Africa


Book Description

Soils of South Africa is the first book in seventy years that provides a comprehensive account of South African soils. The book arranges more than seventy soil forms into fourteen groups and then provides, for each group: • maps showing their distribution and abundance throughout South Africa • descriptions of morphological, chemical and physical properties • a detailed account of classification and its correlation with international systems • a discussion of soil genesis which includes a review of relevant research papers • appraisal of soil quality from a land use perspective as well as for its ecological significance • illustrative examples of soil profiles with analytical data and accompanying interpretations. There is also a fascinating account of the special relationship that exists between South African animals and soil environments. Soils of South Africa should interest students and researchers in the earth, environmental and biological sciences, as well as environmental practitioners, farmers, foresters and civil engineers.

This Land, this South


Book Description

Here is the story of the long interaction between humans, land, and climate in the American South. It is a tale of exploitation and erosion, of destruction, disease, and defeat, but also of the persistent search for knowledge and wisdom. It is a story whose villains were also its victims and sometimes its heroes. Ancient forces created the southern landscape, but, as Albert E. Cowdrey shows, humankind from the time of earliest habitation has been at work reshaping it. The southern Indians, far from being the "natural ecologists" of myth, radically transformed their environment by hunting and burning. Such patterns were greatly accelerated by the arrival of Europeans, who viewed the land as a commodity to be exploited for immediate economic benefit. Cowdrey documents not only the long decline but the painfully slow struggle to repair the damage of human folly. The eighteenth century saw widespread though ineffectual efforts to protect game and conserve the soil. In the nineteenth century the first hesitant steps were taken toward scientific flood control, forestry, wildlife protection, and improved medicine. In this century, the New Deal, the explosion in scientific knowledge, and the national environmental movement have spurred more rapid improvements. But the efforts to harness the South's great rivers, to save its wild species, and to avert serious environmental pollution have often had equivocal results. Originally published in 1983 and needed now more than ever, This Land, This South was the first book to explore the cumulative impact of humans on the southern landscape and its effect on them. In graceful and at times lyrical prose, Albert Cowdrey brings together a vast array of information. Now revised and updated, this important book should be read by every person concerned with the past, present, or future of the South.
