Reconstructing Holocene European Land Cover Using Data-Model Integration. Mauri, A. 279-280:314+. Paper doi abstract bibtex The transition from hunter-gathers to agro-pastoralists led to profound changes in terrestrial ecosystem through deforestation, cultivation, grazing, irrigation and fire, which in turn may have affected regional and global climate over the Holocene. To address these issues, quantitative land cover reconstructions are needed. Previous attempts have been limited by: availability of primary data, availability of methods for interpolating palaeoecological records in space and time, and lack of coordinated efforts between paleoecologists and modelers. Within the ARVE group we have developed a new methodology to map past European land cover based on an innovative synthesis of palaeoecological data and vegetation modeling. The resulting land cover is a combination of potential natural vegetation and anthropogenic land use maps. Potential natural vegetation maps were produced by driving a dynamic vegetation model constrained by soil and pollen-derived palaeoclimate. The use of pollen-derived palaeoclimate represents a novelty in our methodology, which circumvents the use of global climate model output, known to be problematic in certain regions. In parallel, anthropogenic land use maps were produced by translating population estimates into forest cover estimates, distributed by land suitability for arable and pasture. These were optimized by taking into account technological development, archaeological data and pollen-based land use intensity maps for arable and pasture. Using the combination of potential vegetation and optimized anthropogenic land use maps we have produced high-resolution maps of land cover across Europe throughout the Holocene. In future, this will allow us to address a number of research questions, including 1) the time history of human impact in relation to conservation, biodiversity, and land degradation 2) the timing of the spread of civilization throughout Europe and 3) future sustainability of ecosystem processes in the face of human pressures.
