The GREENHOOD project is demonstrating innovative strategies to prevent and reduce nutrient excesses. The project will foster regional nutrient circularity and introduce governance measures that incentivise sustainable practices through region-specific, systemic approach that balances nutrient flows while ensuring economic viability for farmers, industries, and policymakers. The demonstration sites are in Spain, Belgium and the Netherlands, Finland and Norway. BIOEAST HUB CR is contributing to governance model activities, oversees the execution of communication and dissemination activities in Central and Eastern Europe as well as contributes in the execution of “regional twinning” programmes.
