A Guide to USWRLD--The USDA-MSU Version of the IIASA World Food and Agriculture Model and Computer Program

The USWRLD system is the USDA-Michigan State University adaptation of the world food and agriculture model developed by the Food and Agriculture Program of the International Institute for Applied Systems Analysis. This guide provides analysts and computer programmers with (a) a functional description of the model’s representation of the world food and agriculture system and, in particular, the U.S. component; and (b) a description of the structure and use of its FORTRAN program. This will enable both analysts and programmers to communicate with each other in (a) incorporating model improvements and extensions; (b) implementing policy scenarios and options; and (c) interpreting simulation results.
