Abstract: The rural environment has always served as a place of agricultural and animal production, refuge, recreation and leisure for riparian towns in sub-Saharan Africa. With the strong climatic variability and the demographic growth, natural resources undergo intense exploitation which lead to often irreversible ecological imbalances. Biodiversity is plagued by deforestation, wildfires, water pollution, poaching, extinction, the introduction of invasive alien species and overgrazing. This dynamic of agro-pastoral resources was carried out in the Municipality of Ouassa-Péhunco in Benin. The objective of this research is to analyze the mapping of the dynamics of land use units in the Municipality of Ouassa-Péhunco in a context of socio-environmental changes. To carry out this study, the phytosociological records were made. Remote sensing data (SPOT 5 images from 1990, SPOT 6 from 2005 and SENTINEL from 2020) made it possible to assess the various spatiotemporal changes in land use. The mapping of spatiotemporal changes in vegetation revealed that the area of natural plant formations in the Municipality has sharply declined by more than 38.17% between 1990 and 2020 in favor of mosaics of fields and fallows. Closed formations (gallery and riparian forests, dense dry forests and open forests and wooded savannas) fell by 32.95%. Land tenure and land use methods constitute the agricultural management methods among farmers in the Municipality of Ouassa-Péhunco. Cultural practices are based on the exclusive use of chemical inputs.
