The Zou watershed is a significant hydrographic unit located in a region with complex interactions between agro-pedo-geological components and pastoral resources. This study aims to analyze the agro-pedo-geological characteristics and sustainable management of pastoral resources in the Zou watershed at the outlet of Domé in Benin. The data used to describe these characteristics and their spatial distribution comprise climatological, planimetric, pedological, and geological data. The results reveal that the watershed is influenced by a Sudanian climate in the north and a subequatorial climate in the south, with an average annual precipitation of 1116 mm over the period 1991-2020. The classification of vegetation cover shows dominance of savanna (66.31%), plantations (15.61%), and fields and fallows (9.61%), with implications for forage availability and biodiversity. The soils in the watershed are diverse, with a predominance of tropical ferruginous soils, influencing water retention and vegetation production. The geology of the watershed indicates the presence of ancient Precambrian rocks such as granite, gneiss, granito-gneiss, embréchites, and quartzites. These findings underscore the importance of sustainable management of natural resources to ensure long-term availability of water and forage in the region.
