The PAGES LandCover6k Working Group was active from 2014-2021.
Provide the climate modeling community with information on past land use consisting of:
- Pollen-based estimates of land-cover change in quantitative terms, i.e. m2/m2 for plant functional types and three land-cover types, i.e. summer-green and evergreen trees and open land.
- Archaeology/history-based information on major land-use types and associated quantifiable variables relevant to global processes.
Land-use change may imply land-cover change that will affect climate in different ways.
The goal of PAGES’ LandCover6k Working Group was to use pollen, archaeological and historical data to provide information on past land cover and land use change that can be used to evaluate and improve Anthropogenic Land-Cover Change (ALCC) scenarios for palaeoclimate modelling and the study of land-use as a climate forcing.
The latter will improve our understanding of past land cover-climate interactions and the effect of current and future land-use change on tomorrow’s climate.
LandCover6k consisted of four activities:
- Pollen-based land-cover reconstructions (Land Cover, LC).
Coordinator: Marie-José Gaillard.
- Archaeology/History land-use reconstructions (Land Use, LU).
Coordinators: Kathy Morrison, Marco Madella, Nicki Whitehouse.
- Anthropogenic Land-Cover Change (ALCC, HYDE-KK) modeling.
Coordinators: Kees Klein Goldewijk, Jed O. Kaplan.
- Co-design of climate model experiments with the PMIP Community (Clim).
Coordinators: Sandy Harrison, ECR Kamolphat Atsawawaranunt.

LandCover6k and ArchaeoGlobe
LandCover6k and ArchaeoGlobe are two collaborating initiatives that still have to be harmonized. They should not be confused as they do not, for the time being, have the same goals and methods. However, we hope that the two initiatives can be harmonized and merged in the future. Here, we inform on the current differences between the two initiatives. More detailed information can be obtained from the coordinators of the respective initiatives.
The categories LandCover6k and ArchaeoGlobe use to record quantitative data are not the same, as they are collected for different purposes. You are all most welcome to participate in both activities, but read more about the differences between the two activities below to avoid any confusion:
LandCover6k: The goal of LandCover6k was to produce datasets on past land-cover and land-use on continental and global spatial scales that are useful for climate modeling studies on land-use as a climate forcing. The latter was therefore the focus and priority of LandCover6k. It also implies specific methods that are not the same as those used in ArchaeoGlobe.
See above for "Activities" and the associated coordinators.
The LandCover6k LU work packages coordinators were still the same. See the full list of names under the subheading "Work packages" here.
ArchaeoGlobe: The goal of ArchaeoGlobe is to assess levels of knowledge on four land use categories for 10 distinct timeslices of the Holocene - 1. Foraging/hunting/gathering/fishing; 2. Extensive agriculture; 3. Intensive agriculture; 4. Pastoralism.
