We analysed the full set of food crop commodities reported in national food supply and pertinent national production data provided by FAO [19]: for food supply, calories (kcal capita−1 d−1), protein (g capita−1 d−1), fat (g capita−1 d−1) and food weight (g capita−1 d−1); for production, production quantity (tonnes), harvested area (ha) and gross production value (million US$).

For example, according to the USDA, “[W]hen fish are caught in U.S. waters and then processed in a foreign country that foreign country of processing must appear on the package as the country of origin.” Seafood must declare where it was caught and — if it’s outside the United States — where it was processed. After aggregation, 53 crop commodities remained in food supplies data, and 132 crop commodities in production data (electronic supplementary material, table S1).
