Late glacial-early holocene environmental changes in tropical africa : a comparative analysis with deglaciation history

In tropical Africa, glacial-postglacial contrast in precipitation pattern is very great; glacial maximum extreme aridity was followed by the period of increased rainfall during 12,000-5,000 yr B.P. A map showing environmental conditions prevailed in the culmination of the early Holocene wet period at 9,000-8,000 yr B.P. was constructed using published data. The timing of onset and interruptions of the wet period by marked dry episodes at 10,500-10,000 yr B.P. and c. 7,500 yr B.P. were analyzed in connection with the deglaciation history
