This study evaluates the effectiveness of four interventions, Women’ s Empowerment Groups (WEG), Prevention of Malnutrition in Children under 2 Approach (PM2A), Farmer Field Schools (FFS), and the Farmer to Farmer approach (F2F), implemented in the context of a five-year Development Food Assistance Program in South Kivu, Democratic Republic of the Congo. A community-matched quasi-experimental design was used. Primary outcome measures included Household Dietary Diversity Score (HDDS) and the Household Food Insecurity Access Scale (HFIAS). Mean HDDS was significantly greater than the control group for three interventions (FFS, WEG, PM2A; ß: 0.69–0.88, p < 0.001 for all) as was the difference in proportion of households achieving target HDDS compared to the control group (12.3–21.7%, p < 0.001 for all). HFIAS score was significantly lower for all interventions compared to the control group, but smaller gains were seen in F2F (ß: -2.06 - -4.59, p < 0.001 for all). The adjusted difference in proportion of households improving in HFIAS category compared to controls was significant for all groups, but smallest among F2F (15.0–26.7%, p < 0.05 for all). WEG, PM2A, and FFS interventions had significant effects on improving household dietary diversity and food security; the F2F approach was less effective. Food insecurity remained prevalent despite the interventions, suggesting more research is needed to understand the pathways through which they were effective and how interventions could be strengthened to improve food insecurity in post-conflict settings.

Democratic Republic of the Congo 1 Introduction People are considered food secure when they have access, at all times, to sufficient, safe, nutritious food to maintain a healthy and active life—the absence of these conditions is known as food insecurity (FAO 2008). The latest global esti- mates indicate that 795 million, around one of every nine people, are hungry and that of undernutrition prevalence, which measures the proportion of people unable to consume enough food for an active and healthy life, is 12.9% in devel- oping regions (FAO 2015). Household food insecurity is an underlying cause of undernutrition, which is associated with increased risk of child morbidity and mortality and longer- term outcomes of growth stunting and poor cognitive devel- opment (Black et al. 2013; Maluccio et al. 2009; Hoddinott et al. 2008). Programs aimed at improving food security are increasingly recognized as a sustainable approach to address- ing undernutrition (Ruel et al. 2013). Improved household food security has been shown to reduce risk of poor maternal and child anthropometric outcomes (McDonald et al. 2015; Sreeramareddy et al. 2015).
