  1. 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

  2. Ecosystem services (ES) SupportingES • Biogeochemicalcycles • Primaryproduction • Food webdynamics • Biodiversity • Habitats • Resilience Cultural ES • Recreation • Aestheticvalue • Science and education • Culturalheritage • Inspiration • The legacy of the sea RegulatingES • Impactclimate and air quality • Sediment retention • Less eutrophication • Biologicalregulation • Regulation of pollutants Provisioning ES • Food • Inediblegoods • Energy • Space, waterways • Chemicals • Ornamental resoueces • Genericresources

  3. Potential measures to reduceeutrophication Phosphorusreduction • Less rearing of livestock, pigs and fowl • Less fertiliseruse • Increasewastewatertreatment at sewageworks • Private sewagetreatment systems • Catch crops • Morewetlads • Non-phosphate detergents • Bufferzones Nitrogen reduction Less rearing of livestock, pigs and fowl Less fertiliseruse Increasewastewatertreatment at sewageworks Private sewagetreatment systems Catch crops Morewetlads Spreadingmanure at different times of year Energy forest Catalyticconverters at power plants Catalyticconverters on ships Catalyticconverters in trucks Grassland

  4. 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
