This study focuses on the valorization of woody plant species and local communities’ perceptions of climate change, in a context marked by declining rainfall, rising temperatures, and land degradation. Conducted in the rural commune of Kirtachi, the study aims to assess the different forms of use of plant species and vegetation formations, as well as farmers’ perceptions of climate change. Household surveys were carried out with 182 farming households across 20 villages. The results revealed an overall species richness of 86 species belonging to 29 families and 56 genera. Fabaceae was the most represented family (28.75%). Species richness was distributed across the surveyed formations, with 51 species recorded on plateaus, 34 in agroforestry parklands, and 32 within villages. Based on a preferential ranking established by farmers according to socio-economic and ecological benefits, 34 species were identified as priority species. Ten (10) main categories of woody plant use were identified: shade provision, fuelwood, food, soil fertility improvement, traditional medicine, fodder, service wood, windbreaks, construction, and trade. Climate change is perceived by local communities as a slight increasing trend in rainfall and temperature (XX%) and a slight decrease in wind intensity (XX%). According to 84.7% of respondents, these climatic stresses have resulted in reduced agricultural yields. In response, farmers implement a range of adaptation strategies, including physical and biological soil and water conservation measures, soil fertility management, agroforestry practices, livelihood diversification, and integrated production systems, thereby strengthening the resilience of both communities and ecosystems.
