Productivity and Efficiency

According to the U.S. Environmental Protection Agency, water efficiency is the smart use of our water resources through water-saving technologies and simple steps. Using water efficiently will help ensure reliable water supplies today and for future generations. Topics addressed in this theme provide insights, lessons, and guidance on how diverse stakeholders are working to improve water management and reduce water use.

Estimating Productivity of Water At Different Spatial Scales Using Simulation Modeling

Publication date:
January 1, 2001
U.S. Agency for International Development
Implementing real water saving measures in irrigated agriculture is only possible if all the components of the current water balance are clearly understood. Although measurement of all these components is infeasible on a spatial and temporal scale, hydrological simulation models can fill the gap...Read more

Alternate Wet/Dry Irrigation in Rice Cultivation: A Practical Way to Save Water and Control Malaria and Japanese Encephalitis

Publication date:
January 1, 2001
U.S. Agency for International Development
Due to increasing scarcity of freshwater resources that are available for irrigated agriculture, in the future it will be necessary to produce more food with less water. More irrigated land is devoted to rice than any other crop. One method to save water in irrigated rice cultivation is the...Read more

Bunds and Bugs in West Africa: Does Rice Irrigation Threaten Farmers' Health?

Publication date:
January 1, 1999
U.S. Agency for International Development
Wetland water management and irrigation schemes are thought to make a vector borne disease endemic worse in West Africa. The development and promotion of wetland/irrigated rice cultivation has been restrained because of such health concerns. With rapidly growing consumer demand for rice, and the...Read more
