Changes in land use are an indicator of human action on the environment. Several factors influence agropastoralists in the Yakouta watershed in land use and occupation. Climatic extremes are real catalysts for the degradation of the biophysical environment, which is reflected, among other things, in the reduction of plant resources and the drying up of arable land. The needs of rural societies materialize through the use of space and resources, according to techniques and spatial logic that depend on a more or less complex social organization. The pressures exerted on space determine the adaptation responses developed by populations in order to maintain or improve the productivity of the environment. The objective of this study is to establish the link between climate change and land-use strategies in the Yakouta watershed. The methodology consisted in linking remote sensing through the processing of multi-date satellite images (2002, 2010 and 2018) and the analysis of climate data from 1961 to 2018. The results obtained show that more than 35 per cent of the space under consideration has undergone a change of occupation. In terms of climate, the IPS index has made it possible to highlight not only the dry and wet periods recorded since 1961, but also to establish a link between changes in vegetation cover and drought. In the light of these results, the investigations also looked at the adaptation strategies deployed by local populations.
