An analysis of household food waste determinants in Brazilian metropolitan areas

Abstract

Data from the UN's Food and Agriculture Organization reveal that about one-third of global food intended for human consumption is wasted annually. This study investigated the determinants of household food waste in Brazilian metropolitan areas using an online survey. An ordered logit model was employed due to the hierarchical nature of the dependent variable. The results indicated that higher income and education levels correlate with increased waste; however, affluent households exhibited an inverse relationship. Effective nutrition planning reduced waste, while certain kitchen tools, training, and socio-environmental awareness also contributed to waste reduction.
