Each section of the portal is designed to respond to the needs of the facilitators of all of thecatchment areas. The creation of a specific fact sheet describing each catchment area in France isan innovative approach. The information contained in these sheets comes from external databasesbut also from data directly entered by some of the portal’s users. This web portal is linked toother websites in order to make the selection of useful documentation easier and indicate trainingsessions for stakeholders involved in all catchment areas. Finally, the portal disseminates the workcarried out by the resource centre and by numerous partners of this project.
