Second, arid areas, such as the African Sahel and other dry regions in Central America, Africa and Asia, are vulnerable to increases in temperature and changes in precipitation patterns. In many places deserts are expanding, and regions that were barely habitable will become uninhabitable. Studies have shown that local populations have long coped with difficult environmental conditions through migratory strategies: seasonal migration to towns (African Sahel) or pastoralism (Somalia). In such circumstances, desertification triggers adaptive changes in those migratory strategies.
