Climate change disrupts food production while food systems drive environmental degradation. Nearly 800 million people face food insecurity despite abundant global production, and unhealthy diets pose profound health challenges worldwide.
The Food for Humanity Initiative addresses these interconnected challenges through three integrated pillars. Our Food System Dynamics program reveals how climate shocks cascade through global food trade networks — from local harvests to global trade flows — exposing vulnerabilities invisible to traditional analysis. Operational Intelligence & Forecasting builds decision support across the full temporal spectrum, translating climate forecasts into actionable intelligence for frontline decision-makers and shifting from supply-driven alerts to demand-driven platforms that diverse stakeholders can query and act upon. The Living Lab provides hands-on learning where students integrate climate science with agricultural practice, from AI-controlled greenhouses at Lamont campus to circular food systems spanning Columbia's campuses and New York City's urban food ecosystem.
Deliberately lean in structure but active in impact, we educate future leaders, partner with researchers, humanitarian organizations, and city agencies to co-design frontline solutions, and coordinate across our network to mobilize funding, advance research, and get food security intelligence to the people who need it.

From “Just in Time” to “Just in Case”: Agrifood Systems Under Pressure
At a High-Level Political Forum 2026 side event at United Nations Headquarters, speakers described a global agrifood system facing increasingly interconnected shocks, from conflict and climate extremes to crop diseases, financial stress, and disruptions of critical trade routes.
FAO’s Máximo Torero noted that hunger is declining too slowly and unevenly, while acute food insecurity still affects more than 266 million people. Conflict remains the largest driver, followed by weather and climate extremes and economic downturns.
Making Healthy Diets Affordable Requires Careful Sequencing
Food for Humanity Interim Director Michael Puma attended a session at United Nations Headquarters in New York on the forthcoming 2026 edition of The State of Food Security and Nutrition in the World, focused on the high cost of a healthy diet.

For those of you interested in food systems, here’s an update from the Food for Humanity Initiative: “If you have been to the Lamont Doherty Earth Observatory (LDEO) campus, you may recall seeing a very nice but dormant greenhouse next to the Tree Ring Lab. The greenhouse originally came with the Lamont property that was donated to Columbia University in 1948, and had undergone extensive renovations in the early 2000’s thanks to the Department of Earth and Environmental Sciences Chair Kevin Griffin’s research funding…
