It soon became apparent that soil degradation in the Ethiopian Highlands may be posing a threat not only in terms of the physical loss of soils, but also in terms of deteriorating, soil chemical fertility. This study has therefore emphasized both the physical and chemical deterioration of soils due to degradation.

In the Kinangop Plateau of Kenya where small holder farmers have been settled, varied climate and soils occur and the level of land use and management is not as high as may be expected. The climate and soils were therefore studied with a view to identity the constraints they present to land use and management and how the constraints may be rectified. Low temperatures and frequent frosts are the main climate constraints while imperfect drainage, low fertility and shallow effective rooting depth are some of the soil constraints.

Shifting cultivation, under its diverse forms of slash and burn system, is a traditional method of cultivating tropical upland soils, mostly for subsistence purposes. This traditional system of cultivation is in ecological balance with the environment and does not irreversibly degrade the soil resource, provided a sufficient length of fallow is allowed for soil restoration. However, increasing population pressures necessitate more intensive use of land. The consequence is extended cropping periods and shortened fallows.
