“…Lal, 2011). Moreover, capital constraints restrict land users' access to expensive inputs, like fertilizer, that could compensate the deteriorative effects of land degradation (Requier-Desjardins et al, 2011). When land is degraded, its productivity is reduced and many other ecosystem services are deleteriously affected (FAO, 2011).…”

This study compares the results of two nationwide land degradation assessments for Senegal. The first approach is based on expert judgments, the second on trend analyses of Rainfall Use Efficiency (RUE). The comparison yields some interpretable results for extreme negative RUE slope values with maximum degrees of land degradation as indicated by experts, yet, overall, the correlation between both approaches proves to be low and without clear sign. As RUE trend analysis suffers from several inherent methodological problems and expert judgments are found to be consistent we consider expert opinions as the preferable option for a nation-wide land degradation assessment in Senegal. Yet, we argue that methodological improvements would increase the explanatory power of the expert approach and consolidate its position in a policy making framework.

The economics of land degradation has received relatively little attention until recent years. Although a number of studies have undertaken valuation of ecosystem services ranging from the global to the micro level, and quite a few studies have attempted to quantify the costs of soil erosion, studies that address the full costs of land degradation are still scarce. In this review, we attempt to analyze different land resource modeling and valuation techniques applied in earlier research and the type of data used in these analyses, and to assess their utility for different forms of land resource and management appraisal. We also report on the strengths and weaknesses of different valuation techniques used in studies on the economics of soil erosion, and the relevance of these valuation techniques. We make a case for the need for more appropriate models that can make the analysis more robust in estimating the economic costs of land degradation while recognizing the spatial heterogeneity in biophysical and economic conditions.

“…Currently, a wide range of valuation methods have been applied to estimate the costs of desertification or the benefits of combating it. These include productivity change approach (PCA), replacement cost approach (RCA), damage cost approach (DCA), state preference approaches (e.g., contingent valuation, and choice experiments), and benefit transfer approach (BTA) (Requier-Desjardins et al, 2011;Nkonya et al, 2011). The PCA and RCA are the most commonly used methods.…”

A preliminary conceptual framework is proposed for the estimation of the costs of desertification. This framework consists of assessment of the extent and severity of desertification, identification of various impacts, and valuation of the direct and indirect costs of desertification. Based on this framework, three well cited studies of the costs of desertification in China were critically reviewed. Limitations in these studies include double counting, confusion of short-term and long-term costs, and the lack of necessary adjustment of price parameters. Refinement of the estimates indicates that these limitations have caused serious overestimation or underestimation of the costs of desertification. To achieve more reliable and useful estimates, future studies need to overcome the above limitations and use the latest available data on desertification and its various impacts. A more comprehensive conceptual framework that includes the valuation of dryland ecosystem services could also be developed to guide future studies.
