Today 85 million people inhabit the drainage area of the Baltic Sea. The sea is one of the world’s largest brackish water areas and is inhabited by both marine and freshwater species. A mix of land-based human activities, such as agricultural, industrial, and urban activities exert a wide variety of pressures on the sea.

Some of the pressures on the Baltic Sea are exacerbated by the limited level of water exchange, which means that nutrients and other substances from the drainage area accumulate in the Baltic Sea and are only diluted slowly.

HELCOM has identified seven distinct pressures, which are assessed in this chapter:
