Val di Cornia is an area within the Cornia River Mediterranean watershed in central Tuscany (Italy). The demosite area is of about 600 Km2. Groundwater, the main source of water in the area, has been overexploited since the 60s of the last century. During the last 5 years a community-based effort has been trying reverting such process by setting in practice nature-based solutions centred on the Cornia River. River restoration morphological works have been performed since 2017 in order to reconnect the river to the alluvial plain and regenerate riverine habitats, while at the same time, increasing aquifer recharge. Furthermore, a pilot infiltration basin Managed Aquifer Recharge scheme (Figure 2) started its operation in 2018 providing, during the recharge period, riverine wetland habitats mimicking cut meanders environments. All the technical works have been complemented by a two years long participatory process leading to the signature of The Cornia River Contract.
