Scientist at INRAE / SAS

Phone: (+33) 2 23 48 52 27


Address: INRAE, UMR SAS, 65 rue de St-Brieuc, CS 84215, 35042 Rennes Cedex, France

Expertise: water quality, agricultural catchment functioning, agroecology in research, soil and water monitoring at all scales, soil ecosystem services

Keywords: water quality, agriculture, soil and water, agroecology


At SAS, I am currently involved in several research projects: C-N-P transfer in headwater catchments (long-term observatories) and climate drivers; nutrient fluxes in streams and rivers at multiple scales, and land-use and landscape factors; assessment of soil ecosystem services; citizen-based soil science. I am a senior expert on relationships between water quality and rural landscapes, specifically in the context of climate change.

Current projects
  • AgrHys Observatory (INRAE funding): C-N-P transfer in headwater catchments (long-term observatories) and their climate drivers.
  • ADAM (co-funding from the region and the water agency): C-N-P nutrient concentrations and fluxes from headwater catchments to streams throughout Brittany.
  • SoilServ (National Research Agency): assessment of soil ecosystem services.

At the national level of INRAE, I am the joint scientific director in Environment, and through that position, I am currently involved in national scientific coordination of soil and water issues within INRAE, between scientific departments, with other scientific research institutes (e.g. CNRS, Meteo France, CEREMA), as well with environmental agencies (OFB, Ademe), ministries in charge of environment and agriculture, NGOs and economic partners. I co-coordinate the interdisciplinary scientific prospective for research in agroecology. I contribute to the management of a variety of European projects on soil and water issues.

Current projects
  • Clé de Sol (Fondation de France funding): co-built (with UNCPIE, FNE, CA-GE) for a citizen-science project on soils. Co-coordination.
  • EJP SOIL (EU funding): European joint programme on soil, coordinated by Claire Chenu, and for which I coordinate INRAE's involvement for the entire project, and personally involved on a WP on the science-policy interface.
  • CSA Agroecollnet (EU funding): co-built a European network for scaling up agroecology in Europe. Co-coordinated by Heather McKahn. Co-coordination.
  • JPI water: member of the French mirror group; contribute to SRIA, coordinate INRAE's involvement.

Consulting experience

  • I am a regional expert in the Brittany MRAe (Mission for Environmental Assessment) of land planning at multiple scales and projects.
  • I co-coordinated the scientific collective expertise on eutrophication.
