Po Valley (Panaro river, Comacchio valleys, Reno, Emilia Romagna coastal area)
MOTIVATION FOR CHOICE ACCORDING TO HAZARD EXPOSURE AND ASSET VALUE
– The delta of Po river is representing the transition between the river and the sea, and has therefore different hydraulic, morphological and biological characteristics
– Flooding, droughts, coastal erosion, potential storm surge
– Economic engine for Italy (agriculture fisheries, food, manufacturing)
– Biodiversity is at risk (UNESCO protected areas)
POSSIBLE NATURE-BASED AND HYBRID SOLUTIONS
– Seeding of deep rooting plants for river-bank reinforcement
– Debris usage to reduce subsidence
– Enhancement of biodiversity
– Filtration strategies to reduce eutrophication and preserve water quality
– Promote practices to reduce water usage, promoting alternative crops
– Artificial dunes and marine seagrass

The Bellocchio Beach is located at the Emilia Romagna coast of the Adriatic Sea. The beach is a fully natural area and part of the Po Delta Biosphere Reserve. It is strongly affected by marine erosion and in case of storm surges, sea water floods the lagoon threatening freshwater ecosystems and biodiversity. The site preserves a natural heritage, industrial activities (e.g., fish farms) and is embedded in one of the main touristic hubs of Europe. An artificial dune is being constructed as natural barrier between sea and land.
The river Panaro is a tributary of the Po river and flows for its greatest part in the province of Modena (north Italy) with a basin covering a surface of 1775 km2. The OAL aims at mitigating the risk of flooding related to soil erosion on the internal toe of the riverbank which can possibly trigger local or global collapse mechanisms.
Po di Goro
The Po di Goro is located in the Po Delta Biosphere Reserve in the northern part of the Emilia Romagna coast. The Po delta presents a unique identity and biodiversity with ecosystems ranging from coastal sand formations, lagoons, fishing ponds, marshes, fossil dunes, coastal pine forests, brackish wetlands to cultivated land. Tourism together with agriculture and fish farming constitute the main economic activity of local communities. During times of low river flow, salt intrusion reaches far upstream damaging fragile ecosystems. Planting halophytes with the capability of absorbing salts and keeping them inside their cells will support local adaptation.
