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.

Tropical Fishery System Model: Corecs - Continuous Recruitment Simulation

Publication date:
March 1, 1988
U.S. Agency for International Development
The objective of this paper was to develop a continuous-time probabilistic simulation model which depicts salient features of the TFS. Simulation has been defined by Minsky (1986) as a situation in which one system mimics the behavior of another. in principle, a modern computer can be used to...Read more

User's Guide to CORECS -- Continuous Recruitment Simulation Model

Publication date:
March 1, 1988
U.S. Agency for International Development
CORECS is a widely applicable finite time-step (At), numerical population simulation model. The model was designed for applications to a tropical context by utilizing continuous versus discrete decision variables. It was specifically designed to produce stochastic age-independent population...Read more
