The range of work on Africa by geographers provides an redistribution policies. Adepoju (1982) notes four policy types: rural development, resettlement schemes, youth programs, and growth poles/administrative decentralization. If we add to these the types of programs devised to deal with unemployment in Third World cities or the supposed problem of excessive rural to urban migration (Todaro, 1976; Gilbert, 1982; World Bank, 1984), and add to the specifically rural and urban area policies those with a natural scope which aim to alter the internal terms of trades between rural and urban areas, the range of policy-related subjects becomes wide (Table 5.6), and yet any of them have been the subject of geographical enquiry as the illustrative references in the table demonstrate.
