Désertification et civilisation nomade au Sahara: naissances conjointes

Abstract : Since the end of the Würm Ice Period the aridity of the Sahara has been increasing. Men of the Neolithic age have been confronted with a drastic choice : either develop in the remaining wet spots an intensive food production or take advantage of the immense desert areas with their scattered vegetable resources adapting themselves at several levels : biological, social, economic and cultural. Bio- anthropological studies made on some Tuaregs of Central Sahara have thus revealed very performing features in arid areas comparable to those of endemic species (camels, gazelles). The bio-economic, social and cultural over-adaptation of these nomadic shepherds which ensure them the control of large wastes is now threatened by arbitrary territorial, socio-economic patterns which thwart mobility, destroy environment, ruin vegetable and animal resources, devastate a subsoil good for such products as oil, gold or uranium, which, far from benefiting local people, renders them unable to survive in their desert.
