Abstract

1. Katsina province lies in the densely populated Sudan zone of Nigeria, an area in which the human factor is at least as important as the physical environment in determining the nature of the ecosystem. 2. The vegetation types are described and mapped, and the area of cultivable land is found to be 1.5-1.7 acres (0.6-0.7 ha) per head. 3. It is deduced that about 1 acre (0.4 ha) per head is required for subsistence crops each year; and it is suggested that, when compared with the total area of cultivable land available, this figure provides a useful means of estimating the intensity of the human factor under conditions of peasant farming in Africa. 4. It is concluded that Katsina Province is in the final stage of transition from shifting to sedentary cultivation. Conditions are compared with those at Mokwa where the traditional pattern of shifting cultivation is still unimpaired by rising population densities.
