This analysis measures trade-offs between soil loss and food production costs. It is made by means of multigoal interregional programming model. The trade-off curve is derived by means of the prior weighing technique. The results indicate that soil loss from agricultural land can be decreased considerably with very little increase in cost in efficiency in food production. However, the trade-off curve has a "corner" in it, and further reductions in soil loss give rise to sharp increases in food production costs. As higher costs are assigned soil loss, important shifts take place in the interregional patterns of crop production and land use. Also, further decreases in soil loss and increases in food production costs raise food prices for consumers.
