We identified cropland and pastureland abandonment as important drivers for total land use change fluxes in Europe according to the bookkeeping model BLUE. We also used factorial simulations to identify carbon dioxide fertilization and nitrogen deposition as playing important roles in the net biome production reported by the DGVM ORCHIDEE. Taken together, these results point to areas in which uncertainty reduction would have the greatest overall impact of the total net carbon fluxes reported by these models. Such uncertainty reduction is essential to using independent research models in monitoring, reporting, and validation of official greenhouse gas inventories by member states to the UNFCCC.
