This study examines the issue of natural area protection in an urban environment. We report on the results of interviews conducted with a wide range of land use planners in the Chicago region. Of particular interest are the unique goals and challenges of land acquisition programs in a...

We use the location set covering problem to define a natural area site selection model for use in the Chicago region. This framework allows us to explicitly consider the equity of site distribution by stipulating that each population center has access to a recreational space within a specified...

Cost-effective strategies are needed to find and remove diseased trees in forests damaged by pathogens. We develop a model of cost-minimizing surveillance and control of forest pathogens across multiple sites where there is uncertainty about the extent of the infestation in each site and when...

This study uses optimal control theory to examine the dynamic features of agricultural landscapes characterized by spatial externalites. A stylized system of agricultural production and groundwater flow is used to illustrate how spatial externalities affect land use decisions over time. Policy...

In this paper, we use a simple urban economic model to study how choosing park locations within a city might contribute towards urban planning goals. For multiple possible park placements, we solve for the associated equilibrium urban structure, including the equilibrium rent gradient, city...
