The Resilient Sea project aims to restore coastal vitality in the Central Baltic through nature-based solutions. By addressing both nutrient inflows and internal nutrient loads, the project enhances water quality, biodiversity, and ecosystem resilience.

Activities include restoring lagoon thresholds and fish passages, harvesting reed to improve habitats and water circulation, reintroducing submerged vegetation, and constructing wetlands and biochar filters to trap excess nutrients. Innovative methods, such as aluminium treatment and the DWTR phosphorus-binding technique, are piloted across multiple sites. Beyond direct interventions, Resilient Sea develops tools for upscaling, including a municipal toolbox for shallow bay protection, participatory habitat mapping, integrated planning guidance, and a pilot for biodiversity offsetting through Nature Credits. By combining ecological restoration with practical management tools, the project empowers local authorities, communities, and stakeholders to safeguard coastal ecosystems while testing scalable solutions for the wider Baltic region.
