An international "Arid land resource inventories"workshop held at La Paz. Mexico, in late 1980 concentrated on developing cost-efficient inventories for the arid regions of the world. Over 205 participants from 14 countries attended to discuss characteristics of the arid lands, inventory challenges and research needs. Papers were presented on planning techniques, classification systems, remote…

The present volume is an outgrowth from, but not a complete record of, the American Association for the Advancement of Science symposium held in Colorado. Eleven of the 15 papers listed at the symposium are included. Ten additional papers were written later especially for the volume. After the symposium, some of the papers were translated, and many were extensively rewritten in order to present…

Author uses as point of reference the 15 case studies prepared for the United Nations Conference on Desertification, held in Nairobi, Kenya, August 1977. A powerfully written tour of selected anti-desertification efforts around the world. The author paints a series of fascinating big pictures from particular areas of China, Australia, Tunisia, Iran, Israel, Iraq, or the USA. In each case he…

The Inter-Congress Meeting of the International Geographical Union Working Group on Desertification in and around Arid Lands, held at Tucson, Arizona, from 3 to 8 January 1979, was attended by 30 participants from 13 countries. It provided an occasion for reporting on research by members of the Working Group, and also for discussion on activities in connection with the forthcoming International…

Most studies of desertification acknowledge the role of human activity in affecting and often initiating the process. That human activity is in response to a variety of decisions on, and systems of, resource management. An understanding of those decisions should therefore help explain the role of human activity in the desertification process-in effect help to explain why resource management in…

Healthy and stable soils are essential for the production of the increased amounts of food required to meet the needs of the mounting population and the rising expectations of the world's malnourished poor. The book brings the issue of " saving our soils" to a high priority on the world's agenda.It describes theoretical and practical experiences in soil science from many regions of the world.
