FABIO traces every ton of biomass from the field where it grew to the country where it was consumed — across 192 nations, 130 products, and 28 years.
When a German family sits down to a pork dinner, they are consuming Brazilian soybeans, Argentine sunflower meal, and Ukrainian maize — processed through Dutch feed mills and fattened in Niedersachsen barns. None of this is visible at the dinner table, and none of it appears in German agricultural statistics. FABIO was built to make these invisible connections quantifiable. It is, in essence, a wiring diagram for the global food system: 192 countries, 130 product categories, and 28 years of physical flows traced from primary production through processing, trade, and final consumption.
The technical achievement is formidable. Multi-regional input-output (MRIO) models have existed for manufactured goods since the 1970s, but food systems resist the same treatment. Biomass transforms — wheat becomes flour becomes bread, soybeans become oil and meal, cattle consume feed and produce beef and hides and manure. FABIO handles these transformations through physical supply-use tables that track mass balances, not just monetary flows. The result is a model where every ton is accounted for, where nothing appears from nowhere and nothing vanishes.
The policy implications are immediate and uncomfortable. FABIO reveals that Europe's apparent agricultural self-sufficiency masks massive embedded imports of land, water, and emissions from South America, Southeast Asia, and sub-Saharan Africa. When researchers used FABIO to calculate the deforestation footprint of European consumption, the numbers forced a reckoning: the EU's deforestation-free supply chain regulation, adopted in 2023, draws directly on the kind of supply-chain accounting that FABIO pioneered. The 36,000 downloads reflect a dataset that didn't just describe the food system — it changed how governments regulate it.
Countries whose biomass production exceeds domestic consumption, revealing the granaries of the world
Countries whose consumption depends most heavily on foreign agricultural land
| region | production Mt | consumption Mt | net import Mt | embedded land Mha | self sufficiency pct |
|---|---|---|---|---|---|
| EU-27 | 620 | 818 | 198 | 42 | 76 |
| China | 1,240 | 1,524 | 284 | 68 | 81 |
| United States | 890 | 603 | -287 | -34 | 148 |
| Brazil | 785 | 473 | -312 | -52 | 166 |
| Sub-Saharan Africa | 310 | 338 | 28 | 8 | 92 |
FABIO enables consumption-based deforestation accounting, linking European demand to tropical land clearing. The EU's 2023 Deforestation Regulation explicitly requires the kind of supply-chain traceability that FABIO's methodology provides, making this an academic tool with direct regulatory offspring.
By quantifying bilateral biomass dependencies, FABIO reveals which nations face supply chain fragility. Japan's 67% import dependence and Saudi Arabia's near-total reliance on foreign agricultural land expose vulnerabilities that the 2022 Ukraine crisis made painfully concrete.
Beyond biomass, FABIO enables calculation of embedded water, land, and carbon in food trade. These virtual resource flows dwarf direct resource trade in magnitude, revealing that food trade is the dominant mechanism through which wealthy nations externalize their environmental footprint to producing regions.
