Geological and prehistoric studies in North-East Niger over the last fifteen years are now pointing to a synthesis of knowledge concerning both the climatic events occuring in this currently desert region over the last ten millenaries, and the human populations that lived there over the same period. Several remains discovered and dated by the author since 1978 in the Air and the Ténéré provide solid evidence for the new hypothesis that a process of neolithization began in the South Sahara from the tenth millenary before our time, and was favoured by the then humid climatic conditions. The material culture that began at that time is characterized by lithic tools and ceramic work, whose evolution over five and a half thousand years is presen...
