A diverse group of agricultural interventions aim to improve the nutritional status of women and children. These interventions range from the cultivation of bio-fortified crop varieties to home gardening to livestock intensification. We systematically review 42 evaluations of agricultural interventions for improved maternal and child nutrition. Using these evaluations, we identify three intervention typologies - Enhancement, Diversification, and Substitution - that reflect the differential impact of interventions on household livelihoods and patterns of food consumption. Our typologies allow for a nuanced approach to categorize and generalize about pathways of impact for agricultural interventions. In applying our typologies to existing evaluations, we summarize the evidence base and emphasize areas for further inquiry, particularly in terms of understanding these interventions amid complex environmental, political and economic local contexts.
