Global Food Twin

The Global Food Twin is a model that estimates the most likely transportation routes for food flows between producing and consuming regions worldwide. By combining food balance sheets, production maps, trade data, transportation networks, and optimization algorithms, we've created the best guess of how food moves across the globe—from producing to consuming regions—accounting for the complex multi-modal transportation systems. Visit a proof of concept application visualizing this model and global food flows here.

A few facts about the Global Food Twin:

Comprehensive coverage: 82 food groups across 3,787 subnational administrative regions globally
Multi-modal transport: Maritime, land-based (rail, road, inland waterway), and combined transportation routes
Detailed routing: Actual geospatial routes including specific ports, rail lines, and road networks
