Urbanisation in third world countries is occurring under more difficult circumstances compared to what happened in developed countries. El Sammani etal (1989), suggested that the possible explanation for the terrible conditions found in some third world urban areas is that rural-urban migration is so massive as to make it impossible for cities to cope with demands for the various services. Rural-urban migration is accelerated by war and by
