In Niger, land degradation affects more than 100,000 hectares of arable land each year in a context where the need for agricultural and forestry products continues to grow. The objectives of this study, conducted in the commune of Kollo, are to evaluate the economic benefits of SLM and to analyze the dynamics of land use. The methodology of the study is based on a double approach, the use of cartography for the analysis of land use/land cover and cost-benefit analysis to calculate the economic benefits. The study took place in the commune of Kollo, precisely in Sakey Koira Tegui, on a silvopastoral site reclaimed in 2005 by the use of the Delfino plow. The main results show a significant regression (-40%) of natural vegetation formations in the commune, an increase (+10%) in degraded land and (+63%) in cultivated land. In terms of the use of ES, 63% of households use biomass from the site, 54% use NTFPs and 27% use wood. For a cost of 54,800 francs for the restoration of one hectare, the Net Present Value is 9,967,634 FCFA over a period of 13 years. Thus, for each franc invested in SLM, the return on investment is 182 francs.
