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.

Milkfish Production Dualism in the Philippines: a Multidisciplinary Perspective on Continuous Low Yields and Constraints to Aquaculture Development

Published: 
January 1, 1984
U.S. Agency for International Development
Perennial low milkfish yields from underutilized brackish water ponds in the Philippines result primarily from the low fertilizer application rates of most farmers. The purpose of this study, based on a 1981 survey of 447 milkfish farmers in four climatic zones and on data from a previous survey...Read more

Improving Irrigation Management Through Farmer Organization: Responses to a Program in Sri Lanka

Published: 
January 1, 1984
U.S. Agency for International Development
More than most countries, Sri Lanka depends on the irrigated production of paddy to feed its population. About two-thirds of the area devoted to paddy is irrigated, and irrigated areas produce 80% of the total rice crop. There are currently several experiments in Sri Lanka aimed at promoting farmer...Read more
