This database presents an update and expansion of the History Database of the Global Environment (HYDE, v 3.3) and replaces former HYDE 3.2 version from 2017. HYDE is and internally consistent combination of updated historical population estimates and land use. Categories include cropland, with a new distinction into irrigated and rain fed crops (other than rice) and irrigated and rain fed rice. Also grazing lands are provided, divided into more intensively used pasture, converted rangeland and non-converted natural (less intensively used) rangeland. Population is represented by maps of total, urban, rural population and population density as well as built-up area.
Details
The period covered is 10 000 BCE to 2023 CE. Spatial resolution is

contains: a Baseline estimate scenario, a Lower estimate scenario and an
Upper estimate scenario. Currently only the baseline scenario is available
in pastclim
More details on the dataset are available on its dedicated website.
