Interreg South Baltic 2021–2027 · Regenerative Marine Farming
SeaGarden advances community-led regenerative marine farming to cut nutrient pollution and restore the South Baltic Sea.
Why SeaGarden
Across the South Baltic, coastal waters are under pressure from nutrient pollution, unsustainable resource use and limited cross-border cooperation. Eutrophication damages marine life, reduces biodiversity and threatens the communities that depend on clean water.
Community-based regenerative marine farming — cultivating native seaweed, aquatic plants and mussels — removes nutrients, improves water quality and increases biodiversity, without added feed or fertiliser. Well established in the western Baltic but underrepresented in the South Baltic, SeaGarden brings it here through joint frameworks, decision-support tools and practical guidance.
Communities grow native seaweed, mussels and aquatic plants on simple, low-cost lines — no feed, no fertiliser.
As they grow they take up the excess nitrogen and phosphorus that drive eutrophication straight out of the water.
Water clears, oxygen returns, and habitat and biodiversity recover in and around the farm.
The biomass is harvested — permanently removing those nutrients from the sea, for good.
A regenerative cycle — repeated season after season.
What we deliver
Standards, an interactive toolbox and hands-on guidance — the heart of the SeaGarden Knowledge Hub.
A concise transnational document setting standards and best practices for regenerative marine farming; integrates permitting rules, nutrient-uptake guidelines and sustainable water-use practices, aligned with EU and regional environmental directives.
An interactive online tool that displays local environmental and hydrographic data, maps suitable sites, and compares farming methods, with customised guidance for each user group.
A practical collection of methods, tools and technical guidance translating research and pilot results into ready-to-use solutions for communities, farmers, NGOs and SMEs.
