The change in rice crop yield from 1989-2008. Crop yields, the amount of crop harvested per area of land, are used to measure a crop’s performance. Yield trends were calculated from a linear regression of annual crop yield data. Annual crop yield data was calculated from agricultural census reports from 226 countries. Values greater than 0 indicate that the crop yields are increasing over time. Values lower than 0 indicate that crop yields are decreasing over time.
