    What this call funds

    This call funds large demonstration projects that use nature-based solutions to reduce pollution (nutrients, chemicals, plastics, microplastics) and restore biodiversity across connected freshwater, coastal and marine ecosystems. Projects must test and scale up these solutions in real sites, engage public authorities and stakeholders, and monitor results to show measurable progress toward EU ocean and water restoration goals. Funding is expected to support four grants, one for each major European sea/river basin.
