Influencing across multiple levels: The positive effect of a school-based intervention on food waste and household behaviours.

Changing consumer food waste-related behaviours is critical to meeting global targets of halving food loss and waste. This paper presents a food waste reduction intervention trialled in five Australian schools and explores its influence on food provisioning practices, changed behaviours and food waste. Consisting of a mix of educational, skills-based, and whole-of-school-events, the intervention sought to reduce food waste by encouraging students to be more involved at home in choosing and/or preparing food to take to school. Students reported greater involvement in the target behaviours and there was a reduction in avoidable food waste in participating schools. Utilising a multi-level perspective, this study demonstrates how food-related practices and behaviours emerge from the interactions of macro and meso-level factors and highlights the value of this perspective when designing food waste reduction interventions.

Towards a multi-level framework of household food waste and consumer behaviour: Untangling spaghetti soup.

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.

Unpacking sustainabilities in diverse transition contexts: solar photovoltaic and urban mobility experiments in India and Thailand.

It is generally accepted that the concept of sustainability is not straightforward, but is subject to ongoing ambiguities, uncertainties and contestations. Yet literature on sustainability transitions has so far only engaged in limited ways with the resulting tough questions around what sustainability means, to whom and in which contexts. This paper makes a contribution to this debate by unpacking sustainability in India and Thailand in the context of solar photovoltaic and urban mobility experimentation. Building on a database of sustainability experiments and multicriteria mapping techniques applied in two workshops, the paper concludes that sustainability transition scholarship and associated governance strategies must engage with such questions in at least three important ways. First, there is a need for extreme caution in assuming any objective status for the sustainability of innovations, and for greater reflection on the normative implications of case study choices. Second, sustainability transition scholarship and governance must engage more with the unpacking of uncertainties and diverse possible socio-technical configurations even within (apparently) singular technological fields. Third, sustainability transition scholarship must be more explicit and reflective about the specific geographical contexts within which the sustainability of experimentation is addressed.
