The late 20th century has witnessed increasing crises in the world's marine fisheries. A causal analysis of these reveals that a common element are various manifestations of spatial inequity. This most frequently includes the inequity of access rights to the resource, but factors such as variations in resource depletion, spatio-temporal variations in stock recruitment, the imposition of regulatory zoning, destruction of marine ecosystems and the siting of mariculture facilities are other examples. To resolve some of these problems, management practices must be improved.

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.
