Available in PDF, EPUB and Kindle. Book excerpt: The study of soils has taken on increased importance because a rapidly expanding population is placing demands on the soil never before experi enced. This has led to an increase in land degradation. Land degradation is one of the most severe problems facing mankind. Volume 11 of Advances in Soil Science was devoted entirely to this critical area of soil science. The editors of that volume, R. Lal and B.A. Stewart, defined soil degradation as the decline in soil quality caused by its misuse by humans. They further stated that soil degradation is a major concern for at least two reasons. First, it undermines the productive capacity of an ecosystem. Second, it affects global climate through alterations in water and energy balances and disruptions in cycles of carbon, nitrogen, sulfur, and other elements. Through its impact on agricultural productivity and environment, soil deg radation leads to political and social instability, enhanced rate of deforesta tion, intensive use of marginal and fragile lands, accelerated runoff and soil erosion, pollution of natural waters, and emission of greenhouse gases into the atmosphere. In fact, soil degradation affects the very fabric of mankind.

Download or read book Sustainable Resource Development In The Third World written by Doug Southgate and published by Routledge. This book was released on 2019-09-10 with total page 181 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over time, scientists, technologists, and resource managers in affiuent countries have devised and institutionalized methodologies for exploiting and managing natural resources in their own environments with considerable success. In doing so, they have provided models, at least of development and affiuence, that the less developed countries seek to employ. An international symposium involving both invited and contributed papers addressing the technological and institutional challenges of sustainable development of natural resources in the Third World was staged in September 1985 in Columbus, Ohio, co-sponsored by The Argonne National Laboratory of Argonne, Illinois, The Tropical Renewable Resources Program and the School of Natural Resources of The Ohio State University, and the United States Agency for International Development. This volume presents selected papers from the symposium.

Download or read book Food And Natural Resources written by David Pimentel and published by Elsevier. This book was released on 2012-12-02 with total page 531 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food and Natural Resources provides an understanding of the interdependency of food and natural resources that affect society. It is hoped that through these discussions a more complete understanding of these timely issues will emerge. This base of knowledge will help individuals and government leaders develop and implement the types of programs that will result in the effective use and management of land, water, energy, and biological resources for improved food production and a higher standard of living for everyone. The book begins by examining the intrinsic dynamics of natural ecosystems—especially the land, water, atmosphere, energy, and biological components. This is followed by chapters on the availability and interrelationships between population size, arable land, water, energy, and other biological resources; the loss of wild species of plants and animals; the availability of agricultural land for crops and livestock; and the impact of land degradation on food and other resources. Subsequent chapters discuss water use in agriculture; the mechanization of agriculture and food production; the principles and practices that can make agriculture environmentally and economically sound and sustainable; and the impact of population growth on the environment and food supply.

Available in PDF, EPUB and Kindle. Book excerpt: First Published in 2011. Latin America today is similar to Canada in the early 1900s-a sleeping giant, basically underpopulated, whose potential rests on the exploitation of enormous land, forest, mineral, and water reserves. This study, carried out over the period 1967-69, has involved travel throughout much of Latin America north of the Tropic of Capricorn and discussions with people in many different fields, including highway construction, forestry, colonization, and agricultural industries in the forest frontier regions and capital cities of the continent. The collection of data required about twelve months of the author in the field.
