Food waste paradox: antecedents of food disposal in low income households

摘要

This article aims to identify antecedents of food waste among lower-middle class families - a paradox, given the financial constraints this population faces. The importance of this research is evident in escalating environmental pressures for better use of our planet's scarce resources. Given that most of the world is low-income, any behavioral change in this population is likely to have a considerable impact. Empirical data were collected from 14 lower-middle income Brazilian households, based on observations, in-depth interviews, photographs and a focus group (n=6). Five major categories of food waste antecedents were identified: (1) excessive purchasing, (2) over-preparation, (3) caring for a pet, (4) avoidance of leftovers and (5) inappropriate food conservation. Several subcategories were also found, including impulse buying, lack of planning and preference for large packages. Surprisingly, findings show that strategies used to save money - such as buying groceries in bulk, monthly shopping trips, preference for supermarkets and cooking from scratch - actually end up generating more food waste. This mitigates the savings made during the purchasing phase.
