A system-wide interdisciplinary conceptual framework for food loss and waste mitigation strategies in the supply chain

YesThe issues of food loss and waste (FLW) in the global supply chains have recently attracted attention. However, the causes of and strategies for mitigating FLW at different stages of the supply chains remain under researched. Our research aims to address these gaps in knowledge in a three-fold way: i) we identified the key causes (through root-cause analysis) of FLW in the supply chain of developed and less developed countries; ii) we systematically classified measures and policies that have been implemented to mitigate FLW; and iii) we developed an interdisciplinary conceptual framework for waste utilisation practices that can contribute towards the triple bottom-line in food systems. A root-cause analysis was performed and mitigation strategies identified by systematically analysing and synthesising the research published over the past 20 years (1998 to 2018) in the areas of FLW in the supply chain. We propose a conceptual model for the prevention of FLW utilising a systems approach through the concept of a circular economy. Since the agri-food sector is largely interdisciplinary, in our proposed model, we have also demonstrated a method of integrating contributions from multiple disciplines towards achieving total depollution (zero waste) in the supply chain.Support provided by the British Academy/Leverhulme Small Research Grant, Reference No: SG160072, for the development of the study
