Download or read book Proceedings of the Water Harvesting Symposium Phoenix Arizona March 26 28 1974 Classic Reprint written by Water Harvesting Symposium and published by Forgotten Books. This book was released on 2018-03-18 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Proceedings of the Water Harvesting Symposium, Phoenix, Arizona, March 26-28, 1974 Early in 1960, research programs in water harvesting were also initiated in Israel by Hillel and at the University of Arizona by Cluff. Hillel's work now relates primarily to soil smoothing and runoff farming Cluff has done a considerable amount of work on the use of soil sealing with sodium salts and on gravel-covered plastic membranes The most recent innovation in the construction of catchments appears to be the use of granulated wax spread over the ground surface so that the sun will melt the wax and cause it to flow into the soil. The resulting wax coating causes the soil, for some as yet unknown period of time, to become both water repellent and stabilized. After having presented these brief and incomplete excerpts from water harvesting history, as I know it, I would like to quote from a paper published in 1964, in which I attempted to outline the objectives we should strive for in research on water harvesting catchments (10) About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Available in PDF, EPUB and Kindle. Book excerpt: Dry areas suffer not only from limited rainfall but alsonatural leakage'-90% of rainwater is lost directly or indirectly, and is unavailable for agriculture or domestic use.

Book Agriculture in Semi Arid Environments

Download or read book Agriculture in Semi Arid Environments written by A.E. Hall and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: The semi-arid zones of the world are fragile ecosystems which are being sub stantially modified by the activities of mankind. Increasing human populations have resulted in greater demands on semi-arid zones for providing human susten ance and the possibility that this may enhance desertification is a grave concern. These zones are harsh habitats for humans. The famines that resulted from drought during the late 1960's and the 1970's in the African Sahel illustrated the unreliability of present agricultural systems in this zone. Large fluctuations in ag ricultural production have occurred in semi-arid zones of Australia, North Ameri ca, and the Soviet Union due to periodic droughts, even though considerable ag ricultural technology has been devoted to agricultural development in these zones. The challenge to mankind is to manage these different semi-arid zones so that pro ductivity is increased and stabilized, and environmental deterioration is decreased. Irrigation can be used to increase and stabilize agricultural production in semi-arid zones as discussed in Volume 5 of this series, Arid Zone Irrigation. The present volume, Agriculture in Semi-Arid Environments, focuses on dryland farming in semi-arid zones, and is relevant to the large areas of the world where rainfall is limiting and where water is not available for irrigation. This volume is designed to assist agricultural development in these areas and consists of reviews and analyses of available information by scientists working in Africa, Australia, and at the U ni versity of California.
