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 ...

Large databases with multiple variables, selected because they are available and might provide an insight into establishing causal relationships, are often difficult to analyse and interpret because of multicollinearity. The objective of this study was to reduce the dimensionality of a multivaria...

In order to assess the economic impact of heartwater (Cowdria ruminantium infection) and model the impact of improved vaccines against the disease, a field study was conducted to provide data on livestock productivity indicators in Zimbabwe. Cross-sectional studies were performed in the two main ...

Questions as to whether public investment in international agricultural research is a `Good Thing' or not may best be addressed using two arguments: (1) justifications based on whether or not past investments have yielded substantial benefits to societies and the resource-poor; and (2) that futur...
