Estimating the yield effect of soil degradation


, : Estimating the yield effect of soil degradation. Journal of Soil and Water Conservation 47(6): 486-490

Cost-benefit analysis is often used to examine the returns to conservation measures. A commonly-used approximation in such exercises consist of using a constant estimate of the yield decline induced by soil degradation over the period of analysis. This approximation is shown to distort significantly the results of the analysis, both quantitatively and qualitatively.
