This paper examines how controlling livestock trypanosomiasis, transmitted by tsetse-fly (Glossina spp.), affects the rate and location of agricultural expansion in Ghibe Valley, Ethiopia. Control of the disease will reduce animal mortality, increase productivity per animal and cause livestock po...
The question of whether the contentious situation at the Ngorongoro Conservation Area, Tanzania, engendered by human population growth, agricultural intensification and perceptions of proper and sustainable land use, is a prevalent problem on a broader continental scale is addressed.
In southwestern Ethiopia, recent chaotic events, changes in land tenure and introduction of tsetse fly [Glossina tachinoides] control have precipitated changes in the use of land and other natural resources. In turn, these changes have initiated shifts in rangeland biodiversity. Unexpectedly, sma...
For at least five decades, tsetse biologists have observed that the populations of some species of tsetse (particularly species in the morsitans group of flies) decline as fly habitat is converted into cultivated land and host populations are decimated by hunting. Some have even suggested that ts...
It has been hypothesized that the presence of the tsetse fly has protected the biological diversity of the African continent by preventing over-use of ecosystems by people and their livestock. Our objective was to evaluate how changes in land-use, a likely impact of tsetse control, affect selecte...
More effective control of tsetse-transmitted trypanosomiasis may open vast areas of Africa to livestock production, both increasing food production and endangering biodiversity on the continent. This paper Reports on the Development of a conceptual model of the linkages between trypanosomiasis co...
To understand the environmental impacts of controlling trypanosomosis, there are two principle questions to answer: 1) How does controlling trypanosomosis affect the pattern and rate of land-use/land cover change? 2) If these changes occur, how do they affect ecosystem structure and function? For...
Agricultural expansion is a major cause of biodiversity loss worldwide. In Africa, biologists have observed that the populations of some tsetse species, which transmit human and livestock trypanosomosis, decline or disappear as human populations grow and farmers clear fly habitat for cultivation....
