In recent year,:, a large number of computer-based
models have been developeA tc help the agricultural community
analyze trends, identify problems, and evaluate policy
altecnatives. Over 50 modelF with potential for focd and
agricultural issue analysis dere identified. These models vary
by scope. size, methodology, and issues covered. They can be
viewed a.s a hierachical set of analytical tools which can be
used to address several levels of problems, such as local issues
of a specific crop, regional issues iavolving several farm
iaputs, national issues integrating nutrition with production
policies, or global problems addressing population, wealth, and
food. Many of the models identified are single or multicrop
models and are usually confined to a particular region of the
world. Other models are designed to aid understanding of
specific policies or issues such as grain reserve costs under
varying conditions. Still others are highly aggregated, treating
the agriculture as a whole, and are intended to predict general
levels of activity over the short run. A smaller number of
large-scale models exist that are not limited to any particular
time frame and, in some cases, are actually a series of
iateracting submodels combining agricultural and nonagricultural
issues. These models attempt to portray the total food system,
including key factors, such as demography, environment, and
pollution, that influence the system. (Author/SC)](ViewImageLocal?handle=hein.gao/gaobaagyv0001&div=1&collection=&method=preview&ext=.png&size=3)
