The Resources axis

The scientific axis  Resources focuses on understanding the spatio-temporal dynamics of waters and soils under the joint influence of climate and agricultural activities changes. 

The objectives are to detect, understand and predict spatial and temporal changes in hydrological functioning, soil functioning, and carbon-nitrogen-phosphorus biogeochemical cycles. 

This axis (25 people) brings together skills in agronomy, soil sciences, hydrology and modelling.
