Nomadic herders in the Sahara, Africa are facing a critical cultural crisis due to environmental change, specifically desertification and drought. These environmental challenges are forcing them to adapt their traditional ways of life and find new sources of income, which has major implications for their cultural identity and social cohesion. The other groups mentioned may also be facing challenges, but they do not currently face the same level of critical cultural crisis as the nomadic herders in the Sahara.
