We describe a method of fitting a model of germplasm distribution to climate data and illustrate it`s use in mapping the continental distribution of five Stylosanthes species. The climate data used are the monthly totals of rainfall and the monthly mean temperatures and diurnal temperature ranges...

Over the last two to three decades, West Africa has witnessed considerable changes in land use. Unprecedented increases in human population combined with changes in climatic patterns have reduced per capita arable land traditionally available for agricultural production. In the livestock sub-sect...
