How this figure is calculated

Agrifood systems — Emissions (CO2) divided by Land area (sq. km), matched on country and year. Neither publisher issues this ratio as a series; it is computed here from both.

Agrifood systems — Emissions (CO2) ÷ Land area (sq. km)

Computed from

Statizoid computes this series; the underlying measurements belong to the publishers named above. The arithmetic is applied to every country and year where both inputs report, and nothing is estimated unless the page says so.
