Sweetpotato production in unimodal rainfall farming systems in sub-Saharan Africa is constrained by inadequate quality planting material. Technologies for efficient production of sweetpotato planting material are imperative to improve this sub-sector. Consequently, two separate field experiments,...
The Andean blackberry (Rubus glaucus) is an important source of income in hillside regions of Colombia. However, growers have little reliable information on the factors that affect the development and yield of the crop, and therefore there is a dearth of information onhowto effectively manage the...
Climate change is predicted to have major impacts on small-scale farmers in Mexico whose livelihoods depend on rain-fed maize. We examined the capacity of traditional maize seed systems to provide these farmers with appropriate genetic material under predicted agro-ecological conditions associate...
Inadequate nutrition and helminthiasis were among the important constraints to smallscale dairy production identified in a 4-country survey among traditional dairy producers. Consequently, multi-locational trials to study helminth control and supplementary feeding to grazing cattle are being impl...
The purpose of the study was to characterize the differences in epidemiology (risks of infection. morbidity. mortality) and potential control of East Coast fever (ECF) between the selected strata. Evidence of Theileria parva infection was assessed by increased antibody levels as measured in an in...
In Peru, strong growth in urban demand for industrially processed dairy products has induced a rapid increase in milk production along the coast but not so much in the Andean highlands, where an increase in milk production would create the greatest benefits. A farm–household optimisation model wa...
