Impact of land use change on the hydrology and erosion of rain forest land in South Cameroon

Reports & Research
December, 1997
Cameroon

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.

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?

Carbon dynamics in slash-and-burn agriculture and land use alternatives of the humid forest zone in Cameroon

Journal Articles & Books
November, 1997
Cameroon

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.

Data from slaughter (LWT) and warm carcass (HCWT) weights and dressing-out percentages (CYD%) of 209 Uda (Sahel) and 26 Djallonke sheep and 105 Djallonke goats were analysed by fitting a least-squares fixed-effects model. The model consisted of the effects of breed and sex on LWT and CYD% and the effects of breed, sex and LWT (as covariate) on HCWT for the sheep data. The effect of sex alone on LWT and CYD% was fitted for the goat data. As for the goat carcass data, HCWT was regressed on LWT for each sex subclass. Effect of breed significantly affected all carcass traits in the sheep.
