Years: 5085BCE - 4942BCE
Africa has entered a dry phase by 5000 BCE, and the climate of the Sahara region has gradually become drier.
The population has trekked out of the Sahara region in all directions, including towards the Nile Valley below the Second Cataract, where they make permanent or semi-permanent settlements, thereby laying the groundwork for the rise of Egyptian civilization.
A major climatic recession occurs, lessening the heavy and persistent rains in central and eastern Africa.
Dry conditions will prevail in eastern Africa from this time forward.
