Anthromes 12K DGG v1
Anthromes 12K DGG version 1 maps global changes in anthromes over the past 12,000 years from 10,000 BCE to 2017 CE at 60 time points using the HYDE 3.2 land use and population dataset. This version used an updated classification scheme and analyzed data in an equal area Discrete Global Grid format (~96 km² hexagonal “DGG cells”) using an R-code-based system.
Mapping anthromes in DGG format is a major improvement over the geographic grid units used in all prior anthromes versions (5 arc minute grid cells compatible with climate models), overcoming spatial biases in anthrome classification and global statistical assessments of biodiversity in anthromes.
The Anthromes 12K DGG v1 dataset was published April 19, 2021.
