This report addresses the global concern of water development and stresses the need for management of the water demand. Investments in water efficiency, recycling, and conservation are recommended over conventional water supply projects for greater cost behefits and production yield. Topic areas include: (1) water use trends in major crop producing regions; (2) investments in irrigation efficiency (with explanations and analyses of gravity systems, surge irrigation, sprinkler designs, micro-methods, and pitcher techniques); (3) new cropping patterns (containing data on the effects of conservation tillage on water storage and data on water consumption rates of selected crops); (4) recycling and reuse projects (including a listing of selected sites of large-scale water reuse programs); (5) urban water conservation problems (specifying savings with water efficient household fixtures); and (6) impact factors (technology, management practices, and governmental policies).
