More effective control of the tsetse fly in Africa will reduce constraints imposed by the livestock disease, trypanosomiasis. Trypanosomiasis lowers livestock productivity, and in some areas, may limit the ability of farmers to keep livestock and plough the land using animal traction. Control of ...

The effects of 4 years grazing by sheep and goats at various stocking rates on soil surface features, bulk density, organic C, N and P contents and pH were investigated in Sadore, Niger. Studies were also conducted in a fallow subjected to 9 years of intensive grazing. Although grazing reduced (P...
