The Environmental Research Observatory (ERO) AgrHyS focuses on the response times of changing Agro-Hydro-Systems for hydro-chemical fluxes.
An Agro-Hydro System is defined as a catchment influenced by agricultural activity.
This type of catchment is constrained globally by two kinds of forcage:
- The farming activity which induces:
- Changes in spatial structures (plot’s size and shape, buffer zones, wetland transformation, spatial organization of crops and farming)
- Modifications in input flux either water fluxes (irrigation), or organic and mineral fluxes (fertilization, pesticides…)
- The climate as for any ecosystem, with:
- A short term huge variability
- Long term trends related to global changes
