Faced with the growing effects of climate change, Sahelian countries are confronted with major challenges in terms of environmental and socio-economic vulnerability. This study aims to assess the climate vulnerability of these countries in order to guide more targeted emergency and adaptation policies. To this end, we analyzed the influence of various climatic factors (temperature anomalies and extremes, precipitation), environmental factors (water stress, forest cover changes), and socio-economic factors (population growth, access to essential services) on the vulnerability of infrastructures and populations. Through Principal Component Analysis (PCA) complemented by Hierarchical Cluster Analysis and GIS mapping, three vulnerability profiles emerge: highly exposed countries (e.g., Niger, Chad, Mauritania), countries in transition (e.g., Mali, Burkina Faso), and relatively resilient countries (e.g., Cameroon, Nigeria). These findings call for targeted public policies, by optimizing water resource management, strengthening health infrastructures, and developing climate-adapted agricultural practice.
