It convenes 69 institutional and civil society partners (communes, provinces, SPW, farmers, fishermen, tourism operators, sanitation organisms, businesses, and residents) to deliver multi-year Action Programmes (652 actions in 2023-2025), invasive exotic species management (Himalayan balsam, Japanese knotweed, giant hogweed, crayfish), water quality monitoring aligned with the EU Water Framework Directive, flood risk management, and environmental education and awareness services to 34 partner communes.

Product overview
