Abstract

This technical report describes the methodologies and procedures that researchers from the Center for Agricultural and Rural Development and the Department of Economics employed to estimate the costs of adopting new conservation practices and changing agricultural land use in the state of Iowa with the goal of improving water quality. In brief, economic models and data on land use and conservation practices were combined with a watershed-based hydrological model, the Soil and Water Assessment Tool (SWAT), to estimate the costs of obtaining water quality changes from the hypothetical placement of a broad-based set of conservation practices.
