Our simplified model was developed in Swarm using agents with heterogeneous preferences and a landscape with heterogeneous properties. The context of this work is a larger project that includes surveys of the preferences of residents and data on historical patterns of development. Our broader goal is to use the model to evaluate the ecological effects of alternative policies and designs. We begin by evaluating the influence of a greenbelt, which is located next to a developing area and in which no development is permitted. We present results of a mathematical model that illustrates the necessary trade-off between greenbelt placement and greenbelt width on its effectiveness at delaying develop- ment beyond. Experiments run with the ABM are validated by the mathematical model and illustrate analyses that can be performed by extending to two-dimensions, variable agent preferences, and multiple, and ultimately realistic, patterns of landscape variability. %B Proceedings of IEMSS 2002 %P 190 - 195 %8 2002/// %G eng
