Sustainable development - development that meets the needs of the present without compromising the ability of future generations to meet their own needs Ecosystem services Eutrophication- an increase in the concentration of nutrient content to an extent that increases the productivity of organic compounds in the waterbody

Boundaries for reduction of eutrophication • we have not yet fully understood the sources for nutrients high concentrations • visible effects from implementation of measures will not be discernible for decades • a warmer climate towards the end of century might exacerbate eutrophication and make impossible achieving to some strategic goal • political and legislation boundaries, differences in countries surrounding the Baltic Sea • different indicators of achieving strategic purposes • inability of marine ecosystem to stop the process of eutrophication itself when this process is already started • technical boundaries
