Effects of vegetable commercialization on household food security: a generalized propensity score matching approach

Abstract

The commercialization of smallholder farmers is seen as the most significant driver of improved food security and household welfare in most countries with low-agricultural economies. This study used a Generalized Propensity Score Matching (GPSM) approach to evaluate the average causal effects of vegetable commercialization levels on the food security status of households in Sabbata Hawas Woreda, Oromia Region, Ethiopia. Data were collected through surveys of 385 farm households, key informant interviews, focus group discussions, and observations. The results revealed that vegetable commercialization had both positive and negative effects on households’ food security. The MAHFP increased steadily as the levels of commercialization increased. However, the lower levels of commercialization are associated with negative outcomes for calorie intake, food consumption scores, and household dietary diversity scores. The caloric intake, HDDS, and FCS were improved after commercialization levels reached 50%, 40%, and 25% respectively. The findings indicate that an increase in commercialization may not always lead to consistent increases across all indicators of food security and it has heterogeneous effects on households with different levels of commercialization. The subsequent policy recommendations of the study results are that, even though smallholder commercialization strategies are crucial for ensuring increased food production, productivity, and incomes for food security, it still requires taking into account the heterogeneous food security effects of vegetable commercialization levels.
