Tourism is sometimes described as a worthwhile activity for a developing economy. Among countries of emergent Africa, for example, Kenya derives a significant portion of its national economic advancement from tourism. But cogent socio‐economic arguments modify the general proposition for Kenya, as for several other developing countries. If these reservations are accorded proper attention, the tourist may yet prove the unwitting agent for development. If, however, the cost‐benefit construct is not adjusted to take account of these further factors, tourism in emergent Africa may end up by the way it is going in the Caribbean and several other parts of the Third World: a source of economic, cultural, social and ultimately political friction.
