Rainfall, water, sediment yields and evaporation were quantified in three catchment areas with undisturbed rain forest, selectively logged forest, and forest with shifting cultivation respectively. Despite a considerable regional variation in rainfall(1700-2300 mm/a), annual evaporation rates were similar (1209-1314 mm/a). The impact of land use practices on water yield is negligible compared to the effect of rainfall.

One of the environmental consequences of slash-and-burn farming is the loss of forest system carbon which in turn contributes to atmospheric change and impacts upon global climates. International attention has become focused upon the development of alternatives to slash-and-burn agriculture to alleviate poverty, protect biodiversity and reduce climate change. Before alternative land use systems can be evaluated in terms of carbon sequestration, baseline measurements of carbon dynamics resulting from current practices are required.

n all African towns specific modes of transport - mechanized and non- mechanized - have developed which play an essential role in distributing food between different markets and supplying the whole informal trading sector. These modes of transport, which provide an ideal service for the small volumes handled and the weak financial capacity of the wholesalers and retailers, play an essential role in maintaining low-cost inter-urban redistribution. What is known about the “artisanal” sector of urban goods transport?
