Water Harvesting And Supplemental Irrigation For Improved Water Use Efficiency In Dry Areas

With reference to West Asia and North Africa.

This book, which contains 14 chapters, covers all aspects of rainfed agriculture, starting with its potential, current status, rainwater harvesting and supplementary irrigation, to policies, approaches, institutions for upscaling, and impacts of integrated water management programmes in rainfed areas.

Improving Water and Nutrient Use Efficiency in Food Production Systems provides professionals, students, and policy makers with an in-depth view of various aspects of water and nutrient us in crop production. The book covers topics related to global economic, political, and social issues related to food production and distribution, describes various strategies and mechanisms that increase water and nutrient use efficiency, and review te curren situation and potential improvements in major food-producing systems on each continent. The book also deals with problems experienced by developed countries separtaely from problems facing developing countries. Improving Water and Nutrient Use Efficiency emphasizes judicious water and nutrient management which is aimed at maximising water and nutrient utilisation in the agricultural landscape, and minimising undesirable nutrient losses to the environment.

*First title in a major new series *Addresses improving water productivity to relieve problems of scarcity and competition to provide for food and environmental security *Draws from scientists having a multitude of disciplines to approach this important problem In 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.
