The Sahara Desert's expansion is causing significant environmental and socio-economic issues. As mentioned, the southward creep of the desert into the Sahel is exacerbating drought conditions, making it difficult for local populations to maintain their agricultural and pastoral livelihoods. The loss of this farmland leads to food insecurity, pushing communities into poverty and increasing competition for resources. This can, and sometimes has, resulted in conflict and displacement as people migrate in search of more habitable areas.
