Ano: 2005 Temporal and Spatial Evaluation of Soil Conservation Policies AgEcon Lakshminarayan, P.G.; Babcock, Bruce A.. This paper presents estimates of the benefits and costs of alternative soil conservation policies in a spatially and temporally consistent framework. The policies considered are implementation of soil conservation practices with an objective of reducing erosion to a site's tolerance level and a policy with an objective of a voluntary 50% reduction in conventional tillage. Costs and erosion benefits of these two policies are compared with that obtained from CRP. The changes in erosion and cost are estimated relative to 1992 levels. The analysis is conducted on every NRI point in a 12-state region in the north central United States. Erosion metamodels estimated using site-specific resource, production, topography, and weather data make such an endeavor...
