World Farmland Food Capacity Map

How many people could this land feed?

Move the cursor across Earth to estimate the yearly food calories produced in a 10 km × 10 km square, expressed as people receiving 2,250 kcal per day.

Deep red (0/100) shows land with no estimated crop-food calorie production in the historical source. Yellow is intermediate, and deep green is high. Oceans remain uncoloured; shorelines are approximate.

What this measures

Based on EarthStat/Cassidy et al. (2013) estimates for 41 major crops, broadly representing circa-2000 agriculture. The dataset combines reported crop production with the share of crop calories ultimately available as human food, including estimated feed-to-food conversions.

Every original 5-arcminute cell is converted to annual food-calorie output per 100 km² by correcting for its latitude-dependent ground area. A small 10 km square around the cursor samples that raster. The reported number is annual calories divided by 821,250 kcal per person (2,250 × 365).

The map smooths colours between the original 5-arcminute (~5–9 km) raster cells so they are easier to read. This is only visual interpolation, not new measurement detail. The cursor retains the underlying source-cell calculation. The 0–100 score uses a square-root colour scale, capped at the 99th percentile of populated agricultural source cells. It is a relative visual index, not a percentage of food requirements or a calibrated probability.

Crucial limits: This is a historical crop-output energy equivalent. It is not a forecast of what uncultivated land could grow, not a measure of soil fertility, and not a promise of a nutritious diet. Food distribution, seasonal variation, protein, micronutrients and losses between production and consumption are not captured. Historical values may differ substantially from today's production.
