摘要

Background

The COVID-19 pandemic exacerbated food insecurity in Nigeria, particularly among vulnerable households. Home gardening emerged as a potential strategy to improve access to nutritious foods and support incomes. This study examines the impact of home gardening on household nutritional security using cross-sectional survey data from Nigerian households.

Methods

Nutritional security is proxied by the Household Dietary Diversity Score (HDDS), a validated indicator that reflects the variety of food groups consumed over a reference period. To address sample selection bias—where households that engage in home gardening may systematically differ from non-participating households—the study applies a Heckpoisson regression model. This approach accounts for endogenous selection into home gardening and enables the consistent estimation of its impact on dietary diversity. The analysis also incorporates key household demographic and socio-economic variables, including marital status, household size, and age composition.

Results

The study shows that income derived from home gardening is significantly associated with higher dietary diversity, indicating that home gardening enhances access to nutrient-rich foods and supports improved nutritional outcomes. In addition, marital status, household size, and the presence of younger and older household members significantly influence dietary patterns, highlighting the role of socio-demographic factors.

Conclusions

The findings underscore the importance of promoting home gardening as a viable strategy to improve dietary diversity and strengthen household nutritional security, particularly during periods of economic and food supply shocks. Policymakers should consider incorporating home gardening initiatives into broader food security and livelihood programs.
