Addressing aquatic pollution and biodiversity loss through nature positive solutions from source to sea (HORIZON-MISS-2026-03-OCEAN-02)

This topic aims at directly engaging and supporting public authorities and other relevant socio-economic actors (e.g. farmers, landowners, aquaculture producers, tourist operators, fishers, businesses, water management authorities) in addressing aquatic pollution and biodiversity loss, thereby demonstrating and accelerating the transitions needed for achieving one or several objectives of the Mission “Restore our Ocean and Waters”. Proposals are expected to develop, test and upscale systemic approaches that reduce nutrient, chemical and plastic pollution from source to sea, while restoring ecosystem services across freshwater, coastal and marine environments.
