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.

To millions of people in the world, rice is the center of existence, especially in Asia, where more than 90 percent of the world's rice is grown. This book is about the trends and changes that have occurred in the Asian rice economy since World War II, but particularly since the introduction of new varieties of rice and modern technology in the mid-1960s. Although there is now a vast amount of literature and statistical data on various aspects of the subject, no single comprehensive treatment has previously been prepared. The Rice Economy of Asia not only provides such a treatment but also presents a clear picture of some of the critical issues dealing with productivity and equity --- as a glance at the table of contents will show. In addition to 18 chapters, there are an extensive bibilography, 150 tables, and 50 charts. The volume, as a whole, should be interesting and useful to decisionmakers at national and international levels, to professionals, and to students of development.
