International audience Climate change in Siberia and more generally in high latitudes, is impacting strongly the environment and the societies. If the present climate warming evolves as projected, these impacts are likely to increase, greatly affecting ecosystems, cultures, lifestyles and economies. The CLASSIQUE French research project is focused on these questions, with a special attention to land cover evolution, forest vulnerability and permafrost reduction in Siberia. It mobilizes climatologists, hydrologists, agronomists, demographers, geographers and specialists of scientific mediation in a trans-disciplinary effort to better quantify (1) future changes of climate and vegetation properties in Siberia; (2) the consecutive evolution of the agricultural potential of the region; (3) the demographic and societal effects of these changes; and (4) the interactions and feedbacks induced. The chosen approach aims to develop integrated models able to predict the evolution of land cover and hydrology and the links with the Russian population. To predict the future impacts of climate change on Siberian ecosystems, the two French vegetation models (the ISBA and the ORCHIDEE models) will be used and various databases will be developed for their validation on the past thirty years and to identify possible trends. A large interest will be devoted to remote sensing archives which provide surface monitoring and spatial integrated variables on the last thirty years. Various satellite products will be gathered and developed at different scales to assess land surface variables like, land cover / land use and changes, albedo, surface temperature, fire and vegetation dynamics as well as soil moisture, wetlands, snow cover, freezing and thawing periods, etc. A presentation of preliminary products developed and satellite database status will be presented.
