Symphony- a cumulative assessment
tool for MSP
Senior Analyst
What is the problem?

Symphony supports the Ecosystem
Approach in Swedish MSP
• We want to compare the environmental
impact of different plan alternatives
• Cumulative impact is what matters
• We develop a tool called Symphony
• Symphony is based on a scientifically
established method (Halpern et al 2008)

Ecosystem components in Symphony
We have produced about 30 maps of
ecosystem components based on existing data
• Examples: Benthic habitats, fish spawning
areas, porpoises, seabirds, plankton
• Aggregated maps indicate biodiversity
hotspots and sensitive areas

Human pressures in Symphony
We have produced about 25 maps of
human pressures based on existing data
• Examples: Shipping noise, fishing,
military explosions, wind farm bird
avoidance, eutrophication, coastal
exploitation
• About a third of the pressures are
related to MSP
• Aggregated maps indicate areas where
pressures are many and intense

Cumulative impact in Symphony
The cumulative impact is based on
• Number and intensity of ecosystem
components
• Number and intensity of human
pressures
• How sensitive each ecosystem
component is to each human pressure
This map helps to identify areas of
concern, and allows us to compare the
environmental impact of different plan
alternative

Symphony for Ecosystem Approach• We identify areas of particular sensitivity
• We examine the cumulative impact of the MSP draft
• We identify areas where impact is too high
• We analyze which pressures that contribute to the bad situation
• We use this information to discuss with stakeholders
• We develop alternative plan
• We examine the cumulative impact of the new alternative plan
• We iterate until good plan is found
• The method is transparent
• The method can be used in any country and as a basis for transboundary consultations
• HELCOM is using similar method, for assessment
