Finding innovative ways to fight eutrophication in the Baltic Sea

Time: 14:00-14:50

Venue: Lindgrenrummet

We can bring life back to the oxygen-free bottom areas in the Baltic Sea. The poor ecological state of the sea is affecting economic growth and the tourism industry in all nine countries sharing the Baltic Sea coastline. What can be done to reduce eutrophication? We will showcase how oxygenation of vulnerable bottom areas can partly solve the problem. 

The external input of phosphorus from countries around the Baltic Sea has halved since the 1980s. Despite this, the phosphorus content is increasing due to the large internal source of phosphorus linked to anoxic bottom areas of the sea. This internal source has been estimated to be three times greater than the external source. The total input of phosphorus is currently 130,000 tonnes per year. If we want to seriously reduce eutrophication in the Baltic Sea, we must radically decrease its phosphorus content. A large reduction can only be achieved by reducing the internal source. The internal source of phosphorus can be eliminated by oxygenating the anoxic bottom areas.

After an estimated 10 years, the Baltic Sea should be in a condition similar to that during the 1950s, when the external source was roughly the size it is now and the internal source was small. The panel debate is exploring how this can be done and who will benefit from such measures.
