Heartwater, caused by the rickettsial organism Cowdria ruminantium, is a serious constraint to livestock development in much of sub-Saharan Africa. Traditionally, the disease has been controlled by the use of chemical acaricides to control the vector tick. The University of Florida/USAID-supporte...

The potential impact and return to investment from introducing improved dualpurpose cowpea for food and fodder in northern Nigeria was investigated using a combination of farmers' workshops and village and household level surveys. Out of the 462 households surveyed, 41 % were adopters, 9% had bee...

Journal Article 1997

Autor: Reid, Robin S. Wilson, C.J. Kruska, R.L. Mulatu, W.

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...
