Changing consumers' everyday food-related behaviors is crucial in addressing the global food waste challenge. A comprehensive framework of household food waste and consumer behavior is needed to guide targeted interventions and future research agenda. This study reviews developed nations' food waste and behavior studies, presenting a multi-level framework that emphasizes the interactions of factors influencing behavior and food waste. The research highlights the importance of exploring under-explored factors and interactions between factors across levels for effective interventions to reduce household food waste.
Changing the everyday food-related behaviours of consumers is a critical part of tackling the global food waste challenge. Comprehensive frameworks of household food waste and consumer behavior are needed to guide the development of targeted interventions and future research agendas. This study systematically reviews food waste and behaviour studies from developed nations to provide an overview of the current research field. It uses a multi-level perspective to organise the various factors influencing food-related behaviour and proposes a new, multi-level, framework of consumer behaviour and household food waste. A novel addition to the field, the framework gathers factors at micro (individual), meso (household), and macro (external to the household) levels and argues that behaviour and food waste emerge from their interactions. Our review also reveals a research domain with disciplinary and methodological `bald spots' and an over-emphasis on individual level factors. A multi-level research agenda focusing on under-explored factors and interactions between factors across levels is presented, and consideration given to multi-level interventions that support consumer behaviour change to reduce household food waste.
