Team presentation

The EA 3795 GEGENAA was created ex-nihilo in 2004, reassessed in 2008 with a modification of its contours (addition of Archaeology), then renewed in 2012 and 2017. In 2012 the GEGENAA is a founding member of the SFR Condorcet (FR CNRS n ° 3417) which we co-animate axis 1 "Production of Biomass and Environment". In the same way, we are members of the Georges Chappaz Institute of Vine and Wine in Champagne since its creation in 2015 and benefit from a research agreement with INRAP since 2012. We integrate in 2018 the SFR Cap SANTE in its Health / Environment axis. Resolutely transdisciplinary, the EA 3795 GEGENAA covers the scientific fields that concern the impacts of man and society on the components of their environments: water, soil, surface and geomaterials.
