The geographical analysis of the Savannah Zones of north-eastern Nigeria revealed a basic insight on the differentiated development at the meso-regional level: The northern districts had a much lower population increase than the average. It was already arid land before the dramatic reduction of precipitation since the late 1960s. The quality of the soil for farming is rather poor despite specific minerals which give grass during the very short growing season a higher nutritional value than further south. Through studies at the local level, it became evident that on one side this is an area of out-migration of the local population but on the other side we have to register the influx of migrants from the even more dryer northern districts including Niger Republic. The rate of urbanisation in Nigeria increased rapidly from 15 to 36 %. Northern capitals like Kano and Maiduguri multiplied their number of inhabitants seven times but were overtaken by Gombe’s growth. In any case they are centres of social and cultural change as the preliminary findings of H. BALZEREK concerning the boom-town Gombe revealed. But social tensions seem to be inevitable as religious movements not only in big towns like Kano but even in Gombe were already analysed by WATTS (1993, 61). The bearer/ carriers of this movement are landless people who did not migrate to new land in the country side, they are hoping for new jobs in an urban environment. The social structure has changed since the time of the old Hausa towns, but their reliance on surplus of labour force appears to have continued
