World Soil Erosion and Conservation

Book Description
Land degradation from soil erosion has been considered by many to be a problem of significant proportion, affecting some 30-50% of the earth's land surface. At the time of the first publication of this book in 1993, estimates indicated that 10-15 million hectares of land were being lost each year through erosion and salinisation from irrigation and that at such a rate of loss, topsoil reserves on most sloping lands would be depleted within two hundred years. Since humankind's dependency on the land for food is almost total, soil erosion represents a real threat to the security of our food supply. The need for the immediate conservation of the world's soil resources is therefore clear. As part of the response to this need, the International Union for the Conservation of Nature's Commission on Ecology convened a special working group to consider the problem of world soil erosion and to propose practical solutions for soil conservation. This important book presents the outcome of their work.
Vegetation and Soils
Author: S. R. EyrePublisher: Routledge
ISBN: 1351300113
Category : Social Science
Languages : en
Pages : 344
Book Description
Vegetation and Soils is an introduction to the study of vegetation and soil distribution. In this accessible work, S. R. Eyre describes the distributions of these two important elements in the landscape. The book progresses regionally, and the land areas of the earth are subdivided according to the distribution of their main vegetation and soil types. The author argues that the nature of the soil is not determined by vegetation any more than it is determined by climate, but the nature of the vegetation always has some bearing on the nature of the soil, and vice versa.Eyre studies the ways in which plant communities and soil profiles develop and the complexity of the vegetation-climatic relationship. The middle and high latitudes are examined, as well as the tropical regions. In order to avoid broad generalizations of vast regions, the example of the British Isles is used to show that vegetation and soil maps can be misleading on a continental scale. The book concludes with a series of vegetation maps, which show the distribution of plant formations. Also included are tables providing climatic correlations with vegetation and a glossary of relevant terms.This classic work shows the intimate connection between vegetation development and soil development. For this reason, this book is a major contribution to the study of the physical aspects of geography and will be of particular interest to students of geography, botany, and agriculture.
Soils of South Africa
Author: Martin FeyPublisher: Cambridge University Press
ISBN: 1139495291
Category : Technology & Engineering
Languages : en
Pages : 289
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.
