ABSTRACT
In January 1975, the Wright-Ingraham Institute sponsored a workshop which sought to examine the interrelationships of food, people, environment, and climate as they related to global prospects for the year 2000. Energy development and urbanization each suggest a conversion of land use from the present predominantly agricultural use of the watershed. In 1975, the Institute assembled an expanded team to continue the land use research effort. This group decided that it would be valuable to conduct a conference dealing with land use issues facing the watershed. The development of a mathematical model of the watershed system would have been far too complex a chore for a three-day conference. "Trade-off" is another term for cost — undertaking one activity at any time typically requires that another be given up at that time. Land use changes are a response to factors inside and outside the system; these changes in turn affect factors within the system and influencing subsequent changes.
