Few studies of land-use/land-cover change provide an integrated assessment of the driving forces and consequences of that change, particularly in Africa. Our objectives were to determine how driving forces at different scales change over time, how these forces affect the dynamics and patterns of ...

This study illustrates how productivity impacts resulting from livestock research can be measured using a herd simulation model, how the results of this model can be extended spatially using geographic information systems (GIS) to determine the potential increase in livestock production that woul...

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 ...

Trypanosomiasis diseases are caused by single-cell organisms and affect both humans and cattle. This indicative study modelled the effect of climate change and population growth on the future range of tsetse flies, their main vector, in sub- Saharan Africa. Projected climate change to 2030 has a ...

This paper addresses issues surrounding measurment of the potential productivity gains from new livestock technologies and the returns to international livestock research. The approach, applicable to many livestock production constraints and technologies, uses geographic information systems (GIS)...

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...

Better data: currently, the quality of GIS analyses is constrained by poor data on the distribution of current tsetse populations, non-human and human trypanosomosis prevalence, livestock population densities, agricultural production, biodiversity, soil fertility, land-use, infrastructure, income...

This paper highlights the growing divergence between the supply and demand for livestock products in sub-Saharan Africa with special reference to the Preferential Trade Area (PTA) region. Livestock diseases, especially theileriosis and trypanosomiasis, among other constraints, are identified as a...
