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.

Published:
January 1, 1995U.S. Agency for International Development
The recent development of technology for the ocean culture of juvenile giant clams (family Tridacnidae) in the South Pacific has brought attention to the predatory activities of a hitherto little studied mesogastropod genus, Cymatium (family Ranelidae). The results of research into relevant aspects...Read more

Published:
January 1, 1995U.S. Agency for International Development
A major problem perennially faced by an agricultural economy like the Philippines is low agricultural productivity. With the scarcity of agricultural land that can be additionally cultivated, the country's thrust therefore is towards maximizing productivity in this sector to adequately feed...Read more

March 1, 1992U.S. Agency for International Development
Aquatic resources are important for livelihood and consumption. Fish, including finfish, crustaceans, mollusks and seaweeds, are the fifth most important agricultural commodity. Developing countries catch and produce 52 million tons annually, over half of the world production. At least 50 million...Read more

Published:
June 1, 1991U.S. Agency for International Development
The Work Plan for Cycle II outlined experiments designed to test the hypothesis that organic maintenance fertilizer inputs would perform better, in terms of fish production and of water quality, than inorganic inputs with equivalent contents of total nitrogen and phosphorus. The CRSP freshwater...Read more

Published:
June 1, 1988U.S. Agency for International Development
Monte Carlo optimization with constraints was used to estimate parameters of "skew-normal" selectivity curves for gillnets. Non-linear functions of mesh size were explored in addition to the linear ones described by Wulff (1986). This methodology can be used to estimate the parameters for...Read more
