Global or world models are concerned with the application of systems analysis to policy problems of intra and international interest. Typical problems of concern include population growth, ecological is-sues (forestry, fisheries, pesticides, insect infestation), energy and water resource availability and uses, the spread of diseases, and environmental models (acid rain, air pollution), Clark and Cole (1975), Holcomb (1976). Global models are usually highly aggregated in their structure and in their data requirements. However, such models can be developed by integrating lower-level and more detailed national or regional models. Of related interest are global and regional predictive models that deal with long-range weather or macro-economic activity.

Although the trail of global models leads back to Malthus and his publication of An Essay on the Principle of Population(1798), the modern development of global models begins with the use of systems analysis in the study of global...
