Available in PDF, EPUB and Kindle. Book excerpt: This report contains a collection of papers from a workshopâ€"Strengthening Science-Based Decision-Making for Sustainable Management of Scarce Water Resources for Agricultural Production, held in Tunisia. Participants, including scientists, decision makers, representatives of non-profit organizations, and a farmer, came from the United States and several countries in North Africa and the Middle East. The papers examined constraints to agricultural production as it relates to water scarcity; focusing on 1) the state of the science regarding water management for agricultural purposes in the Middle East and North Africa 2) how science can be applied to better manage existing water supplies to optimize the domestic production of food and fiber. The cross-cutting themes of the workshop were the elements or principles of science-based decision making, the role of the scientific community in ensuring that science is an integral part of the decision making process, and ways to improve communications between scientists and decision makers.
Download or read book Water Productivity in Agriculture written by J. W. Kijne and published by CABI. This book was released on 2003 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: First title in a major new seriesAddresses improving water productivity to relieve problems of scarcity and competition to provide for food and environmental securityDraws from scientists having a multitude of disciplines to approach this important problemIn a large number of developing countries, policy makers and researchers are increasingly aware of the conflicting demands on water, and look at agriculture to be more effective in its use of water. Focusing on both irrigated and rain-fed agriculture, this book gives a state of the art review of the limits and opportunities for improving water productivity in crop production. It demonstrates how efficiency of water use can be enhanced to maximize yields. The book represents the first in a new series of volumes resulting from the Comprehensive Assessment of Water Management in Agriculture, a research program conducted by the CGIAR's Future Harvest Centres, the Food and Agriculture Organization of the United Nations and partners worldwide. It will be of significant interest to those working in areas of soil and crop science, water management, irrigation, and development studies.
Download or read book Irrigation Water Pricing written by François Molle and published by CABI. This book was released on 2007-01-01 with total page 367 pages. Available in PDF, EPUB and Kindle. Book excerpt: Much hope has been vested in pricing as a means of helping to regulate and rationalize water management, notably in the irrigation sector. The pricing of water has often been applied universally, using general and ideological policies, and not considering regional environmental and economic differences. Almost 15 years after the emphasis laid at the Dublin and Rio conferences on treating water as an economic good, a comprehensive review of how such policies have helped manage water resources an irrigation use is necessary. The case-studies presented here offer a reassessment of current policies by evaluating their objectives and constraints and often demonstrating their failure by not considering the regional context. They will therefore contribute to avoiding costly and misplaced reforms and help design water policies that are based on a deeper understanding of the factors which eventually dictate their effectiveness.

Download or read book Production Economics written by Chauncey T. K. Ching and published by Transaction Publishers. This book was released on 1985-01-01 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: By combining information from microeconomics, mathematics, production functions, and temporal and spatial related production analyses, this book provides a variety of essential information to agricultural economics, economics, and business students. Empirical application of production theory and technique is presented at great length; actual data collected from various agricultural enterprises and experiments are used for production function analyses; and methodological and statistical problems commonly encountered in empirical research are carefully addressed. This book fulfills two great needs in the agricultural economics profession: a textbook suitable for senior-level and graduate students that develops and illustrates how calculus and linear algebra can be used in understanding production economics; and for a scholarly work that illustrates empirical applications and results of production function analyses and production theory.

These sources provide a broad spectrum of experience from less-developed to more-developed countries. The aim has been to make an assessment of the claims concerning irrigation water charging as a tool for cost recovery (achieving financial sustainability) and demand management (achieving resource sustainability).
Download or read book The Economics and Management of Water and Drainage in Agriculture written by Ariel Dinar and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 930 pages. Available in PDF, EPUB and Kindle. Book excerpt: Jan van Schilfgaarde, USDA Agricultural Research Service and National Research Council Committee on Irrigation-Induced Water Quality Problems In 1982, a startling discovery was made. Many waterbirds in Kesterson National Wildlife Refuge were dying or suffering reproductive failure. Located in the San Joaquin Valley (Valley) of California, the Kesterson Reservoir (Kesterson) was used to store agricultural drainage water and it was soon determined that the probable cause of the damage to wildlife was high concen trations of selenium, derived from the water and water organisms in the reservoir. This discovery drastically changed numerous aspects of water management in California, and especially affected irrigated agriculture. In fact, the repercussions spilled over to much of the Western United States. For a century, water development for irrigation has been a religiously pursued means for economic development of the West. The primary objective of the Reclamation Act of 1902 was, purportedly, the development ofirrigation water to support family farms which, in turn, would enhance the regional economy (Worster, 1985).
