The cultivation of newly introduced mung bean, a short-season crop with drought resistance, is gaining prominence as a potential remedy for precipitation deficits in arid lands. This thesis aims to quantify the impact of cropping mung beans on household income and food security. Cross-sectional household-level data were collected from 384 samples in East Belessa Woreda, Amhara, Ethiopia. The food consumption score (FCS) was used to measure food security. Collected data were analyzed using a logit regression model and Propensity score matching (PSM). The logit model was applied to estimate the propensity score by taking mung bean production participation as a dependent variable. Mung bean appears more likely cultivated by households that are led by Young age, unmarried, educated household heads and spouses and have a higher number of active families, larger farm sizes, access to credit, and agricultural extension. PSM impact estimation result shows participating in mung bean production significantly impacted participant households' annual income by 17,287 birr ($323) compared to the non-participants'. The finding reveals the need to expand agricultural extension services to create awareness about mung bean production in line with export standards and ways of mixing mung bean into the food diet. In addition, it necessitates smoothing the restriction on transacting mung bean from the Ethiopian commodity exchange authority to create a better market for the product.
