ALFSEN, KNUT H.

Soil erosion and soil mining are important environmental problems in many developing countries and may represent a considerable drag on economic development. The cost of soil degradation depends, however, not only on the productivity effects it has on agricultural growth, but also on how the agricultural sectors are linked to the rest of the economy. This article describes an integrated economy soil-productivity model for Ghana, and through several simulated scenarios we calculate the drag on the Ghanaian economy of soil mining and erosion, and illustrate the effects of different policies aiming at a reduction in these environmental problems.
