Abstract
This study examined the effectiveness of community-based campaigns in reducing household food waste in urban communities of Oyo State, Nigeria, specifically Atiba, Afijio, Oyo West, and Oyo East Local Government Areas. A cross-sectional survey was conducted among 255 adult household members selected through stratified random sampling across high, middle, and low-income zones. Data were collected using a pretested questionnaire capturing sociodemographic characteristics, campaign awareness, participation, exposure frequency, information sources, and self-reported changes in food waste behavior. Chi-square tests assessed associations between campaign participation and reported changes, while ordered logistic regression examined the influence of exposure intensity. Determinants of participation were analysed using binary logistic regression incorporating demographic, perceptual, and exposure-related predictors. Communication strategies were evaluated by categorising respondents’ information sources into media, interpersonal, institutional, mixed, and other channels. Results showed a significant association between campaign participation and reduced household food waste (χ²(4) = 16.755, p = 0.0022), with higher exposure increasing the odds of greater reductions (OR = 1.334, 95% CI: 1.036–1.718). Awareness was the strongest predictor of participation (OR = 34.045, p < 0.001). Media (30.6%), mixed (27.8%), and interpersonal (25.0%) channels were most common. Findings demonstrate that community-based campaigns can reduce household food waste, supporting urban environmental sustainability and resource conservation. It is recommended that policymakers and local authorities strengthen and scale up such campaigns, integrating diverse communication channels to sustain household behavioral change.
