Impact of CSA Innovations on Household Food and Nutrition Security: Evidence From the Upper Blue Nile Highland of Ethiopia

Abstract

Background: Food insecurity remains a major challenge to smallholder farmers in the face of changing climate in the Upper Blue Nile Highlands of Ethiopia. To improve food and nutrition security of climate change vulnerable smallholder farmers in eastern Ethiopia, several climate-smart agriculture (CSA) innovations have been adopted and scaled-up. However, the impact of these innovations on household food and nutritional security was not systematically studied. This study examined the impact of selected CSA technologies on household food and nutrition security. Cross-sectional data were generated from 424 randomly selected rural smallholder agriculture households in the five selected agroecosystems of the Upper Blue Nile Highlands of Ethiopia. The study employed propensity score matching and endogenous switching regression estimation models. Results: Households that practiced crop residue management had an 8.46 higher Food Consumption Score (FCS) and a 0.4 higher Household Dietary Diversity Score (HDDS) than non-adopters. Similarly, households who adopted compost and agroforestry had a 0.462 and 0.446 higher Household Dietary Diversity Score (HDDS) than non-adopters, respectively. The endogenous switching regression analysis result showed that households that practiced crop residue management had an 22.6 higher Food Consumption Score (FCS) and a 2.2 higher Household Dietary Diversity Score (HDDS) than non-adopters. Similarly, households who adopted physical SWC had a 2.3 higher Food Consumption Score (FCS) than non-adopters. Whereas, compost and agroforestry had a 0.28 and 2.12 higher Household Dietary Diversity Score (HDDS) than non-adopters, respectively. Conclusions: This shows that households adopting CSA innovations are more likely to have higher food security compared to non-adopters. This suggests that promotion and scale-up of CSA innovations in the study area can enhance household food and nutrition security.
