Eutrophication is one of the major threats to the biodiversity of the Baltic Sea. Good status of the sea cannot be reached before nutrients causing eutrophication (nitrogen and phosphorus) are reduced in the sea.

Improving municipal waste water treatment remains a remarkably cost-efficient measure to reduce phosphorus loads. BASE is assessing the nutrient reduction potential from small and scattered settlements in Leningrad and Kaliningrad regions in Russia.

Agricultural sector is the main source of land-based nutrient pollution. BASE is taking the good results achieved under BALTHAZAR and promoting increased capacity for organic manure management in Kaliningrad, Russia.
