- W2109554807 abstract "THE question of the progressive desiccation of Africa and the consequent expansion of the desert areas has received considerable attention in the scientific literature dealing with the continent. In West Africa it is the region comprising the Sahara and the western Sudan which has been most closely studied from this point of view. It is widely believed that this region is becoming increasingly arid and that the populous countries between the Sahara and the humid belt bordering the Gulf of Guinea are in process of degeneration into an inhospitable wilderness. Important contributions to this subject have been made in recent years by Professor E. P. Stebbing,1 who taljes a more gloomy view of the future of West Africa than any of his predecessors in this field. He believes that the fertility of the farmlands of the northern provinces of Nigeria is threatened by the encroachment of sand from the Sahara and that the natural vegetation is dying out and being replaced by drier types owing to the drying up of the water supplies. The northern provinces of Nigeria have a population of eleven and a half millions, with an average density of 40-58 to the square mile. They form a rich agricultural region with an export trade in groundnuts, cotton, and hides and skins which is a most important factor in the economic life of the Protectorate. In 1936 the export of groundnuts alone was 218,389 tons, with a cash value of ?2,847,414. The groundnuts are grown in the most northerly districts, precisely those which, according to Professor Stebbing, are in immediate danger from the advancing Sahara. The destruction of these districts would have serious consequences for Nigeria, and the note of warning sounded by Professor Stebbing cannot be ignored. There are however observers with considerable experience in West Africa who are not in accord with many of Professor Stebbing's conclusions. The problem of desiccation was recently investigated by an Anglo-French Forestry Commission, to which the present writer was attached, and which toured northern Nigeria and the French Niger" @default.
