The notable pattern that the countries of the Sahel region share is their location in a transitional zone between the Sahara Desert to the north and the savanna ecosystems to the south. This semi-arid region, encompassing parts of countries like Mali, Niger, and Chad, faces challenges such as desertification and food insecurity. The Sahel's climate patterns are characterized by low and highly variable rainfall, impacting agricultural productivity and economic stability. Consequently, countries in this region often experience similar developmental issues related to climate and resource management.
