This review finds agriculture-nutrition research to have a strong geographic focus on sub-Saharan Africa, concerned especially with nutritional impacts on women and children. Few projects consider the entire evidence chain linking agricultural input or practice to nutritional outcomes. There is comparatively little current research on indirect effects of agriculture on nutrition, or the effect of policies or governance. Most research is focused on undernutrition and small farmer households. There is very little work on the cost-effectiveness of agricultural interventions.
