Abstract
This paper is the third component in a four part series that together describe an integrated modeling framework related to agricultural land use and water quality that has been constructed for the Upper Mississippi River Basin (UMRB). The purpose of this modeling system is to assess the cost-effectiveness of alternative policies concerning conservation practices on agricultural landscapes. The first two papers describe the data and modeling techniques used to calibrate the Soil and Water Assessment Tool (SWAT) model (Arnold et al., 1998) for the UMRB. In this companion paper, we identify a suite of conservation practices to place on parcels based on simple rules of thumb concerning proximity of a parcel to a water body, the slope of the land, and other land characteristics. We then assess the cost of this suite of practices and the water quality improvement predicted by the SWAT model. The economic models and data used to estimate the costs are described and summarized as are the spatial distribution of the conservation practices implied by the rule of thumb followed for conservation practice placements.
