Abstract: This World Map of Organic Agriculture presents territories as proportional in size to their share of the total of world organic hectares (such a map can be referred to as an equal-area cartogram or a density-equalising map). The map accounts for 37.2 million hectares of organically managed agricultural land (certified organic and in-conversion organic) from 160 countries, and here distributed across the 200 territories of the reference map. It is generated by the Worldmapper GIS algorithm developed at the University of Sheffield as a cartographic visualisation tool.
