Regenerative marine farming for a living South Baltic Sea.
SeaGarden advances community-led regenerative marine farming to cut nutrient pollution and restore the South Baltic Sea.
Why SeaGarden
The challenge
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.
The solution
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.
Turning nutrient pollution into a regenerative cycle.
No feed, no fertiliser — just the sea's own species doing the work.
01 Cultivate
Communities grow native seaweed, mussels and aquatic plants on simple, low-cost lines — no feed, no fertiliser.
02 Absorb
As they grow they take up the excess nitrogen and phosphorus that drive eutrophication straight out of the water.
03 Restore
Water clears, oxygen returns, and habitat and biodiversity recover in and around the farm.
04 Harvest
The biomass is harvested — permanently removing those nutrients from the sea, for good.
A regenerative cycle — repeated season after season.
Who is this for?
Built for the people who manage, work and live by the coast.
What we deliver
Three flagship outputs, free and open.
Standards, an interactive toolbox and hands-on guidance — the heart of the SeaGarden Knowledge Hub.
Joint Framework Guidance
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.
Decision-Support Toolbox
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.
Technical Toolkit for Practitioners
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.
On the water
Pilot Sea Gardens across four countries.
Living laboratories in Germany, Poland and Lithuania, building on a Danish forerunner farm — where nutrient removal, biodiversity and viability are put to the test.
How the work is structured
Four work packages, one regenerative goal.
Management & Coordination
Smooth, efficient project execution: coordination, financial management, quality, risk, and continuous communication between partners and stakeholders.
Technical and Integrated Knowledge Base for Regenerative Marine Farming
Builds the shared technical knowledge base: reviews methods, develops the Decision-Support Toolbox and Technical Toolkit, and makes tools openly available to maximise uptake.
Implementing Community-Driven Regenerative Marine Farms – Pilot actions
Establishes pilot “Sea Gardens” in the South Baltic for community-based regenerative marine farming, testing nutrient-removal performance and refining techniques.
Cross-Border Knowledge Hub and Uptake Pathways for Community-Based Marine Farm Solutions
Anchors long-term impact: the SeaGarden Knowledge Hub, cross-border uptake, capacity building, and policy alignment.
Our partners
A six-partner consortium around the South Baltic.

The SeaGarden website is live
The SeaGarden website is now published at seagarden.ku.lt. The site sets out what regenerative marine farming is and why it matters for the South Baltic, introduces the six partners and the pilot Sea Gardens planned for Germany, Poland and Lithuania alongside the Danish forerunner farm, and explains how the work is organised across the four work packages. News and events are published as the project runs. The Knowledge Hub is where SeaGarden’s three flagship outputs will be published as they are completed: the Joint Framework Guidance, the Decision-Support Toolbox and the Technical Toolkit for Practitioners.

SeaGarden partners meet in Kerteminde on 23–24 September
The SeaGarden consortium meets in Kerteminde, Denmark, on 23–24 September 2026 for the second part of the project kick-off. It is the first time the partners from Lithuania, Germany, Poland and Denmark come together in person, after the online kick-off in June. The two days pair working sessions with time on the water. Day one covers good practices for implementing community-driven regenerative marine farms — methodologies, site selection and monitoring. Day two turns to policy integration, guidance and knowledge infrastructure, and the co-design of the project’s Decision-Support Tool.

SeaGarden consortium holds its online kick-off
The SeaGarden consortium met online on 19 June 2026 for the project’s official kick-off, three weeks after the project started on 1 June. Partners from Lithuania, Germany, Poland and Denmark used the session to confirm governance arrangements, walk through the work plan and agree the first activities of the 36-month project. Klaipeda University leads the project and coordinates WP1 Management & Coordination. The meeting confirmed the leadership of the three thematic work packages: Gdynia Maritime University leads WP2, building the technical knowledge base behind the Decision-Support Toolbox and Technical Toolkit; Alles Alge leads WP3, establishing the pilot Sea Gardens; and EUCC – The Coastal Union Germany leads WP4, which anchors long-term impact through the SeaGarden Knowledge Hub, capacity building and policy alignment.
