Check the PanBaltic potential of macroalgae cultivation and of harvesting wild stocks in the user-friendly ODSS online platform

Sustainable cultivation and harvest of macroalgae plays a key role in meeting the goals of blue growth initiatives in the coming years as maritime activities are expected to increase.

To secure space for macroalgae cultivation, spatial planners need to know which environmental variables drive plant production as well as where productive areas are located. First, University of Tartu pooled together all available data on environmental proxies and algal production to quantify relationships between macroalgal production and the environment as well as to predict macroalgae production at the Baltic Sea scale. Second, they built a similar model for macroalgal beach-cast and predicted the potential beach-cast production at the Baltic Sea scale. The resulting maps are useful for maritime spatial planning because they enable to detect the most suitable areas for macroalgae farming and/or beach-cast harvesting. From the range of suitable sites, it is then possible to detect areas that allow long term cultivation actions while considering trade-offs and avoid conflict with existing industries (e.g. fisheries, shipping routes etc). Information is accessible for everyone through the user-friendly ODSS online platform at http://www.sea.ee/bbg-odss/Map/MapMain This guides public authorities interested in setting up / investing in / funding a farm in their region to private actors who want to get involved in the macroalgae business.
