Enablers and barriers of harnessing food waste to address food insecurity: a scoping review.

Despite producing sufficient food for the global population, the growing prevalence of food insecurity in developed countries is cause for concern. The millions of metric tons of food wasted each year could be used instead to drastically lower rates of food insecurity and address food sustainability. In this scoping review, we aimed to identify barriers to and enablers of harnessing food waste across food sectors, including food retail, households, and food rescue organizations, to address food insecurity in a developed country, Australia. The findings demonstrate that research on and responsibility for harnessing food waste for food insecurity has predominantly fallen on ill-equipped food rescue organizations. Three primary policy advancements paramount to harnessing food waste to address food insecurity include (1) improving partnerships and subsidies to minimize transportation costs for redistributing imperfect or surplus food from farmers and retailers to those who with food insecurity; (2) enhancing existing partnerships and subsidies to stably involve more nutrition experts in food rescue organizations to improve the quality of foods being redistributed to those facing food insecurity; and (3) initiating interventions and campaigns that combine the following 5 characteristics: free to the participants; address food literacy; use multiple mass-media tools; are age tailored; and frame messages within personal values.
