The JRU in brief

The Joint Research Unit Soil, Agro- and Hydro-systems, spatialization (UMR SAS) is established in Rennes with a secondary site in Quimper.

We study the interactions between agriculture and the environment using a integrative and spatialized approach of rural areas. Our main interests are water, nitrogen carbon and phosphorus cycles in cultivated landscapes, as well as multi-criteria assessment of agrosystems. Our research contributes to elaborate sustainable agricultural systems, to improve rural landscape management, to preserve natural resources such as water, soil, atmosphere and landscape quality.

UMR SAS includes experts in soil science, hydrology, agronomy, environmental assessment, animal science, bioclimatology and geomatics. It develops models and computer-based tools (MEANS platform, TERRIT’EAU, SYST’N, GEOSAS…) and runs long term experimental facilities such as   Agrhys catchments, EFELE site and MEGEVE plateforms. It is part of the OSUR research consortium and maintain regular collaborations with many institutions around the world.
