The Sahel is a semi-arid region located in Africa, stretching across the continent from the Atlantic Ocean in the west to the Red Sea in the east. It serves as a transitional zone between the Sahara Desert to the north and the Savanna to the south. The Sahel includes parts of several countries, including Mali, Niger, and Chad, and is characterized by its dry climate, limited rainfall, and unique ecosystems. This region faces significant challenges, including desertification, food insecurity, and climate change. The Sahel is home to diverse cultures and communities, relying on agriculture and livestock for their livelihoods. Efforts are ongoing to address these challenges and promote sustainable development in the area.
