Evaluation of Costs Associated with Regional, Environmental Impact in Chesapeake Bay

Robert Walker

In this article, environmental impact in Chesapeake Bay is examined, particularly as it relates to the health and maintenance of Striped Bass populations valuable to both sports and commercial fisheries. A dynamic simulation model is developed using optimal control theory to calculate accumulating opportunity costs of fish population decline caused by pollution in the Bay. The model is then applied to the actual situation using data on Striped Bass populations and rates of habitat loss resulting from disappearing submerged aquatic vegetation. The model is set up to provide information that can be used in benefit-cost analysis, and the impact cost is calculated over time periods during which environmental conditions are modeled to change.
