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.

Socio-Economic Impact and Farmers' Assessment of Nile Tilapia Culture in Bangladesh
Published:
January 1, 1992U.S. Agency for International Development
A socioeconomic study of tilapia culture in seasonal ponds in Bangladesh indicated that these unused or under-used seasonal water bodies, most of which are actually ditches, can be beneficially used for farming tilapia. The tilapia culture technology is simple, requiring very low labor input and...Read more
