Abstract. Information on historical land-cover change is important for understanding human impacts on the environment. Over the last decade, global models have characterized historical land-use changes, but few have been able to relate these changes with corresponding changes in land-cover. Utilizing the latest global land-use change data, we make several assumptions about the relationship between land-use and land-cover change, and evaluate each scenario with remote sensing data to identify optimal fit. The resulting transition rule can guide the incorporation of land-cover information within earth system models.

Short summary
Earth system models require information on historical land cover change. We present a transition rule to generate land cover change from newly developed land use dataset (land-use harmonization, LUH2). The resulting forest cover, vegetation carbon and emissions from land use and land cover change are simulated and evaluated against remote sensing data and other studies. This rule can guide the incorporation of land-cover information within earth system models for CMIP6.
