Why So Much Food is Lost: Inside Global Food Supply Chains

Global food systems produce more than enough to feed the world—yet nearly one-third of all food is lost or wasted. Much of that loss happens far upstream, driven by perishability, cold chain failures, infrastructure gaps, climate pressures, and supply chain inefficiencies that span continents. In this episode, we’re joined by Dr. Chris Mejía, founder and director of the MIT Emerging Market Economies Logistics Lab, along with Drs. David Hidalgo and Mauricio Gámez, researchers who model solutions for supply chain issues. They unpack why food supply chains are uniquely vulnerable to disruption, especially in emerging markets, and where the biggest opportunities exist to reduce loss. From circular economy models and food recovery strategies to AI-driven forecasting, optimization, and community-based distribution networks, the conversation explores how better logistics, smarter data, and cross-sector collaboration can help redesign food supply chains that are more resilient, sustainable, and equitable.
