It is widely acknowledged that food loss and food waste have a detrimental impact on the economy, the climate and the society, which has led to an increasing societal and academic interest in food loss and food waste reduction. Reducing food loss and food waste (henceforth FLW) is easier said than done, as it FLW is a complex and multifaceted problem, to which no straightforward solution exists. The objective of this project is to identify the drivers and barriers of FLW reduction behaviour from an actor perspective, and to explore possible solutions to the FLW problem across the food supply chain. The literature research specifically targets human behaviour within the food system. Insights from this report are intended to form a starting point for the development of successful intervention strategies to bring about behavioural changes that lead to FLW reduction throughout the food supply chain. An extensive literature search was performed in Scopus, Web of Science, ABI/Inform, CAB Abstracts and PsychInfo in November 2018. The exact same search was performed in October 2019, to add new publications in Q4 2018 and 2019 to the results. This search resulted in 489 papers. Based on title, abstract and our purpose of covering all actor domains, 63 papers were selected and summarized, highlighting the theoretical basis, actor in the chain, drivers for waste reduction, drivers for food waste, intervention description (if there was one) and the main results and conclusion. This literature study showed that most studies focus on drivers and barriers of FLW behaviour, and less on behavioural interventions to reduce FLW. Furthermore, the overview of drivers and barriers along the food value chain shows that most of them relate to the consumer level, followed by the retail and hospitality sector. It seems that the current literature provides fewer insights into behavioural drivers and barriers at the agricultural and manufacturing level. Most identified interventions focused at FLW of the consumers as end-user: interventions at the retail level focus on providing consumers with options (or opportunities) to reduce FLW, whereas household-level interventions focus on enhancing consumers' motivations and abilities to reduce FLW. Because a large part of FLW occurs at the consumer level, this focus is understanda...
