Impact of Crop Diversification: Insights on Improving Household Food Security and income Generation in Southern Ethiopia
This study employs Propensity Score Matching (PSM) Model to assess the impact of integrated cultivation of Enset, Coffee, and Avocado on dietary diversity and household income in the southern and southwestern regions of Ethiopia. Using data from various sources, the analysis investigates how different crop combinations in smallholder farming systems influence both nutritional outcomes and economic stability for local households. The study compares households that adopted integrated crop cultivation (treatment group) with those that did not (control group) to estimate the causal effects. The findings reveal that integrated crop cultivation significantly enhances dietary diversity and boosts household income. The R-squared values for dietary diversity (0.65) and household income (0.70) demonstrate strong model fits, indicating substantial explanatory power. Sensitivity analyses and cross-validation confirm the robustness of these results. The study underscores the potential of crop diversification in enhancing food security and economic resilience in smallholder systems. Policy recommendations emphasize the promotion of crop diversification and improved market access to maximize these benefits. Future research should explore the long-term effects and consider broader geographic contexts to validate and expand upon these findings.
