The scientific community recommends a substantial improvement in the knowledge of aquifers, the establishment of reliable monitoring networks and a greater involvement of the administration and users to achieve a sustainable management of aquifers. The main objective of the AQUIFER project is to capitalise, test, disseminate and transfer innovative practices for the preservation, monitoring and integrated management of aquifers, which support decision-making in groundwater management. It also aims to improve technology transfer to local stakeholders, create new synergies and develop common tools in a context of water scarcity and environmental threats. The main innovative element of the AQUIFER project is the consideration of the problem in its entirety: experimentation of management tools on the “quantity” and “quality” components of water: recharge management, hydrological monitoring and network modelling, in particular. It is also intended to detect, test and implement innovations thanks to the 3 water clusters linked to a network of actors in the water sector, and the creation of a decision-making tool to disseminate good practices through the creation of a transnational web platform.
