A critical review of on-farm food loss and waste: future research and policy recommendations

Abstract

Abstract On-farm food loss and waste is estimated to be 16% of the total agricultural-related greenhouse gas emissions globally, and reductions in these emissions have the potential to make a significant impact on climate change. There is a plethora of research being undertaken in this area across countries, food supply chains and stakeholders. However, differences in definitions, quantification methods, understanding of drivers and proposed solutions can be difficult to navigate. This narrative review provides a critical overview of the current research landscape of on-farm food loss and waste. The review has two objectives. Firstly, it provides a stock-take of on-farm food loss and waste definitions, quantification methods, causes and management options. Secondly, it provides researchers, policy makers and industry stakeholders with recommendations on opportunities to be pursued.
