Aquaculture
According to the World Resources Institute, aquaculture—or fish farming—has grown rapidly to meet world fish demand, more than doubling production between 2000 and 2012. New research shows that aquaculture production will need to more than double again between now and 2050 to meet the demands of a growing population. Resources available in this sub-theme include aquaculture development strategies, country-wide aquaculture project reports, and institutional practices for aquaculture strengthening, among other resources that support improving aquaculture globally.

Steady and Unsteady Flow of Fresh Water in Saline Aquifers
Published:
June 1, 1972U.S. Agency for International Development, Colorado State University
Problems of flow involving fresh water overlying saline water in aquifers and methods for their analysis are reviewed. Equations amenable to mathematical solution generally involve the idealization of treating the fresh water as a distinct zone separated from the underlying saline water by a sharp...Read more
