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.

Rising geopolitical tensions and global trade volatility have revealed a key power struggle: supply chains are a matter of national security. This year’s annual report from the congressional U.S.–China Economic and Security Review Commission warns that China has begun weaponizing key supply chain chokepoints, from critical minerals to foundational semiconductors, creating risks that reach far beyond trade.

In this episode, we’re joined by Livia Shmavonian and Josh Hodges, two commissioners of the U.S.–China Economic and Security Review Commission, along with Professor Yossi Sheffi, Director of the MIT Center for Transportation and Logistics. They discuss key findings from this year’s report: why companies have been slow to recognize the strategic nature of their dependence on China, how subsidies and overcapacity distort global competition, and why innovation remains the United States’ greatest advantage. From U.S. manufacturing limitations to critical mineral processing to market access in China, the conversation explores what’s at stake, what must change, and how companies and policymakers can prepare for a future where supply chain strategy is inseparable from national security.

As global supply chains face new waves of political uncertainty, regulatory change, and economic pressure, one thing remains clear: sustainability still matters. The latest State of Supply Chain Sustainability Report from the MIT Sustainable Supply Chain Lab reveals that despite federal environmental rollbacks and shifting investor priorities, companies continue to see sustainability as central to long-term success.

In this episode, we’re joined by Dr. Josué Velázquez Martínez, director of the lab, and Dr. Sreedevi Rajagopalan, a research scientist in the lab. They unpack key findings from this year’s survey—why 80% of firms say sustainability is vital to their future, where companies stand in tracking Scope 3 emissions, and which energy sources could redefine sustainable freight transportation. From biofuels and hydrogen to the data behind carbon accounting, the conversation explores what’s driving progress and why collaboration may be the most necessary sustainability strategy of all.
