Accurate and precise measurements of global cropland extent are needed for monitoring the sustainability of agriculture at all scales. Recent advancement in remote sensing and land cover mapping methods have greatly increased the ability to estimate cropland area distribution and trends. This map of agreement/disagreement was produced by consolidating information at pixel level from six high-resolutions maps (10-30m). The input datasets represent the most advanced land cover and thematic layers available today for cropland area extent circa 2020. Main concepts and input datasets are described in the pre-print "Measuring the world's cropland area" (https://www.researchgate.net/publication/361812372_Measuring_the_world's_cropland_area) submitted for publication under Matters Arising of the Nature Food journal (https://www.nature.com/natfood/research-articles).
Pixel values in the map range from 0 to 6, where 0 represents pixels where all the six datasets agree that there is no cropland; 1 are pixels where only one of the dataset depicts cropland; 2 are pixels where two datasets depict cropland, etc.. Pixel values 4, 5, and 6 represent conditions of good and complete agreement among the input datasets. This map has a spatial resolution of 1km. Users are invited to refer to the metadata contact for access to higher resolution versions of the layer.
