Abstract: Desertification, defined as the loss in productive capacity of the land, has spawned research in decision making involving multi-objective situations. In this study, computer simulation of both the physical and biological processes is used to assess various options available to resource managers. System dynamics of semiarid rangeland watersheds, the example used in this case, are simulated to determine the complex interactions between environmental processes and management actions. With the assumption that the computer simulation models are reasonable facsimilies of the real world, managers can determine the effect of proposed actions prior to their implementation.
