How GEOGLAM Uses Satellite Data to Strengthen Global Food Security: A Look at Early Warning in Action

The Global Agricultural Monitoring (GEOGLAM) initiative, featured in this video from the Group on Earth Observations (GEO), brings together global partners to track crop conditions using satellite data. GEOGLAM helps identify early signs of food insecurity and provides trusted, consensus-based information to decision-makers before crises escalate.

One of the speakers in the video, Christina Justice—Early Warning for Early Action Co-Lead for NASA Harvest and Lead of the Crop Monitor for Early Warning at GEOGLAM—explains how the system supports faster and more informed response. “The Crop Monitor for Early Warning provides timely and consensus-based information on crop conditions and development that allows policymakers to act quickly before humanitarian crises arise,” she says.

The video includes a case study from Malawi, where GEOGLAM collaborated with the Food and Agriculture Organization (FAO) and the Malawian Ministry of Agriculture. By collecting in-season data and conducting field assessments, the team was able to provide timely crop condition updates to inform national planning and food security interventions.

This short video highlights how collaboration, transparency, and open data are helping countries build resilience to shocks and support vulnerable communities around the world.
