This dataset is one derivative product from GAEZ v4 for year 2015 that includes gridded (5-arcminute resolution) irrigated and rainfed crop harvested area and crop production for 26 different crops/crop categories (please see GAEZ_2015_Dimension_crops.csv for the full list).

FAOSTAT yield data for all countries and crops does not directly reported yield values for the years 2009-2010 and 2014-2016. Hence, yield values were calculated from production and area, ( http://www.fao.org/faostat/en/#data/QA ). For this dataset, the 2015 crop yield grids were computed by doing a grid cell by grid cell division of crop production by crop harvested area, for all crops, both irrigated and rainfed. For each crop, m, and grid cell, k, crop yield in 2015 was computed as the ratio of crop production in 2015 to crop harvested area in 2015. Note: For many grid cells and many crops, the harvested area in this dataset is zero and the yield value is reported as -3.39999999999999996e+38.

Unit of measure

Crop Yield: tonnes per ha (1000 kg ha-1; 0.1 kg m-2)
