From ecosystem services to benefits of the Baltic Sea - indicators and threats

image of From ecosystem services to benefits of the Baltic Sea - indicators and threats

Eutrophication, oil spills, and invasive species. Indicators and human benefits from ecosystem services of the Baltic Sea. These were the token of discussion at the ”Nordic Workshop on Economic Analysis of the State of the Baltic Sea, NorWEBS” in Helsinki on 19-20 November 2009, arranged by MTT Agrifood Research Finland. A joint researcher team of economists and marine experts assembled at the workshop to discuss the three main threats to the ecology of the Baltic Sea and find respective indicators of the state of Baltic Sea to be used in economic valuation. Economic valuation of the ecosystem services is required for a comprehensive cost-benefit analysis on protective measures. Based on the presentations and discussions held in the NorWEBS-workshop we propose a framework for deriving the combined benefits from the Baltic Sea ecosystem services.



NorWEBS –survey

The Nordic Workshop on Economic analysis of the state of the Baltic Sea (NorWEBS) survey was sent to 37 marine ecosystem experts and economists in all the littoral countries (Denmark, Estonia, Finland, Germany, Latvia, Lithuania, Poland, Russia, Sweden) and Norway in November 2009. The survey elicited information on the problems affecting the Baltic Sea, indicators of these problems, links between scientific measures and observable quality changes, and national special interests to provide input to valuation studies. The survey had 15 questions on three subjects: eutrophication, oil accidents and invasive species. The response rates were 52% (13/25) and 25% (3/12) for workshop participants and non-participants respectively. The discussion in the NorWEBS workshop in Helsinki 19.11.2009 to 20.11.2009 was based on these answers.
