Food loss is a major problem throughout the world and there are many reasons why food loss occurs. This research investigates the impact of country level factors on food loss across the harvest, storage, processing, and transportation stages of the global food supply chain. A thorough literature review was carried out to examine various research papers on factors causing food loss and the most pertinent country level factors were chosen for the study. Food loss and country level factors data was obtained for several countries and spanning several years, and multiple regression analysis was carried out. The findings of this research and similar studies in future can have a significant impact on devising policies and fuelling investments to improve food supply chain infrastructure for reducing food loss across the world.
