註釋

Traditional linkages between ruminant livestock (cattle, sheep and goats) and soil productivity in the West African Sahel is reviewed, and the adequacy of such practices in light of changes taking place in the region is assessed. Suggestions are given for ways in which nutrient cycling could be improved and made part of a broader strategy to enhance sustainable crop-livestock production
