The Sahel region is a semi-arid zone in Africa that stretches across the continent from the Atlantic Ocean in the west to the Red Sea in the east. It lies between the Sahara Desert to the north and the Savanna to the south. The Sahel includes parts of several countries, including Mali, Niger, Chad, and Senegal, and is characterized by a mix of grasslands, shrubs, and occasional trees. This region faces significant challenges, including climate change, desertification, and food insecurity. The Sahel is home to diverse cultures and communities, relying on agriculture and livestock for their livelihoods. Efforts are ongoing to address these issues and promote sustainable development in the area.
