Pasture area as a fraction of total agricultural area (sum of pasture and cropland). This share, given by HYDE 3.1, is used to derive cropland and pasture area fraction for KK10 and KK10D scenarios, for which original data are provided only for total land use, representing the sum of pasture and croplands. This share is given specifically for each year where HYDE data are available, but shown here only for 1500 (Left) and 1850 (Right). This share changes little before 1500 and after 1850. Pasture area as a fraction of total agricultural area is zero in the Americas in 1500 CE and before, reflecting that pasture land use was minor or absent in agricultural systems of the pre-Columbian Americas.
