Abstract

Geological and archaeological data from the now hyper-arid Eastern Sahara of Egypt, Sudan, Libya and Chad reveal close links between climatic variations and prehistoric occupation during the Holocene. At about 8,500 B.C.E., the Sahara´s margin shifted up to 800 km north to latitude 24° N within a few centuries, bringing monsoonal rainfall to most of the former desert. Savannah-type vegetation and the formation of lakes and temporary rivers resulted in the rapid dissemination of wild fauna and swift reoccupation of the entire Eastern Sahara by prehistoric populations. Relatively stable humid environments prevailed over 3,200 years until about 5,300 B.C.E. The roughly parallel southward retreat of monsoonal precipitation can be tracked the discontinuance of lacustrine deposits and the abandonment of prehistoric settlements at decreasing latitudes. The resulting southward movement of human settlement implied significant changes in pattern of behavior and land-use. - (IfL)
