UMR ECOSYS - Ecologie fonctionnelle et écotoxicologie des agroécosystèmes


History and localization of the unit

 The INRA-AgroParisTech ECOSYS Joint Research Unit was created on 1 January 2015 through merging of the Environment and Field Crops (EGC) unit (head of unit, Enrique Barriuso between 2010 and 2015), the INRA Physicochemistry and Ecotoxicology of Soils of Contaminated Agrosystems (PESSAC) unit (head of unit, Christian Mougin, 2010-15), and the INRA and AgroParisTech staff of the Soil Organic Matter team of the BIOEMCO unit. This last group of staff had been previously integrated to the EGC unit since 1 January 2014. The EGC unit was created at the Grignon site in 2000 by the grouping of two units: the Bioclimatology and Soil Science unit and the Plant Ecophysiology team of the Agronomy unit. The PESSAC unit was created at the Versailles site in 2006 as the INRA pole of terrestrial ecotoxicology. This unit was the result of the merging of the Soil Science unit from Versailles (INRA Environment and Agronomy division - EA) and the Xenobiotics and Environment team of the Phytopharmacy unit (INRA Plant Health and Environment division - SPE).

The ECOSYS supervisors are INRA (EA and SPE divisions, with the EA division as pilot division) and AgroParisTech (Agronomic, Forestry, Water and Environment Sciences and Engineering division - SIAFEE). Currently, the unit is located in three buildings, two at the Grignon site and one at the Versailles site. The whole unit will be regrouped in Saclay in 2021.

Structure of the unit

The unit is organized into disciplinary scientific teams, with transversal themes. Following the recommendations of the last evaluation committee, we started the five-year period with four scientific teams: Ecotoxicology, Soil Science, Plant Ecophysiology and Bioclimatology. In 2016, we merged these last two teams with the creation of the Eco&Phy team (Ecophysiology and Physical Chemistry of Vegetation-Atmosphere Interactions) (Fig. 1). Each of these three teams are preferentially located in one of the three buildings of the unit. Transversal themes are built on the conceptual framework of ecosystem services and define outputs from our research that contribute to certain ecosystem services. These transversal themes ensure a part of the valorization of the results, while simultaneously contributing to the structuring of the academic and R&D partnership as well as training through research. Technical groups common to the unit, whose staff remain attached to the scientific teams, ensure the development and maintenance of shared devices and tools. A "management and common services" team groups all support services and collective missions (Fig. 1).
