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.

Abstract
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.

Abstract: (french)
Au Niger, la dégradation des terres touche chaque année plus de 100.000 hectares de terres arables dans un contexte où les besoins en produits agricoles et forestiers ne cessent de croitre. Cette étude menée dans la commune de Kollo a pour objectifs, d’évaluer les retombées économiques en matière de GDT et d’analyser la dynamique d’occupation des terres. La méthodologie de l’étude est basée sur une double approche, l’utilisation de la cartographie pour l’analyse de l’occupation/utilisation des sols et l’analyse coûts-avantages pour calculer les retombées économiques. L’étude s’est déroulée dans la commune de Kollo précisément à Sakey Koira Tegui sur un site sylvopastoral récupéré en 2005 par l’utilisation de la charrue Delfino. Les principaux résultats montrent en deux décennies, une régression importante (- 40%) des formations végétales naturelles dans la commune, une augmentation (+ 10%) des terres dégradées et (+63%) de surface de culture. En termes d’utilisation des SE, 63 % des ménages utilisent la biomasse du site, 54% les PFNL et 27% le bois. Pour un coût de 54 800 francs pour la restauration d’un hectare, la Valeur Nette Actualisé est de 9 967 634 FCFA sur une période de 13 ans. Ainsi, pour chaque franc investi dans la GDT, le retour sur investissement est de 182 francs.
