Attempts at settling or sedentarizing nomadic herders in semi-arid and arid regions have been largely unsuccessful, partly on account of the difficulty of restricting the movements of domestic livestock in areas where low and irregular rainfall lead to scant and unreliable sources of water and grazing. But for the herders in sub-humid regions, where both water and vegetation resources are much more reliable and substantial, there appear to be different possibilities.

Eighteen plants traditionally used for the treatment of human and animal helminthiasis in Africa were screened for anthelmintic activity using the Nippostrongylus - rat model. Aloe barteri, Terminalia avicennioides, Annona senegalensis, Cassia occidentalis, Anogeissus leiocarpus and Diospyros mespiliformis showed significant activity, giving deparasitizations of 92, 89, 75, 69, 60 and 58% respectively compared to untreated controls.

This report presents the results of an exercise to model forest industry development in Liberia. It presents background information about Liberia and the forestry sector, then discusses the trends and projections in forest cover and production and trade of forest products. It suggests that forest resources will not be able to meet future demand for wood and recommends that forest plantations should be planted to meet this demand.

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.
