A System-Wide Interdisciplinary Conceptual Framework For Food Loss And Waste Mitigation Strategies In The Supply Chain

The issues of food loss and waste (FLW) in the global supply chains have recently gained attention. However, causes for FLW and their mitigation strategies for curbing FLW at different stages of the supply chains remains under researched. Our research aims to address these research gaps in a three-fold way: i), we identified key causes (through root-cause analysis) of FLW in the supply chain of developed and less developed countries; ii), systematically classified measures and policies, which have been implemented to mitigate FLW; iii), developed an interdisciplinary conceptual framework for waste utilisation practices that can contribute towards the triple bottom-line in food system. A root-cause analysis was performed, and mitigation strategies identified by systematically analysing and synthesizing the extant research published over the past 20 years (1998 to 2018) in the areas of food loss and waste in the supply chain. A conceptual model for the prevention of FLW utilising a systems approach through the circular economy concept has been proposed. Since the agri-food sector is largely interdisciplinary, we have also demonstrated a method of integrating contributions from multiple disciplines in our proposed model towards achieving a total depollution (zero waste supply chain).
