After 2500 BC, people began to leave the Sahara due to increasingly arid conditions that transformed the region from a once fertile area with abundant water and resources into a desert. Climate change led to the gradual drying up of lakes and rivers, making farming and hunting unsustainable. As a result, communities migrated toward more hospitable areas, such as the Nile Valley and other regions with reliable water sources. This shift was part of a larger trend of human adaptation to changing environmental conditions.

As the rains diminished and grasslands transformed into desert, the landforms of the Sahara shifted dramatically. The once fertile plains gave way to vast sand dunes, rocky plateaus, and dry riverbeds, creating a harsh environment that was less conducive to agriculture. This transformation influenced migration patterns, as people sought more hospitable regions with water sources and fertile land, leading to movements towards the Nile Valley and regions further south. The evolving landscape not only impacted human settlement but also shaped the cultural and economic interactions among migrating populations.
