Why is Sahel growing smaller?

The Sahel region is experiencing shrinkage primarily due to climate change, which has led to increased desertification, reduced rainfall, and higher temperatures. These environmental changes negatively impact agriculture and water resources, making the land less viable for habitation and farming. Additionally, human activities such as deforestation and unsustainable land use practices exacerbate soil degradation, further contributing to the region's decline. Together, these factors create a cycle of vulnerability for communities in the Sahel, driving migration and increasing competition for scarce resources.
