To create a strategic, ecosystem-based marine spatial plan, the Swedish government has developed the Symphony analytical tools using an integrated cumulative impacts framework. Modeling cumulative impacts allows them to better understand how multiple stressors affect a mosaic of ecosystems with varying vulnerability across space, and thus plan strategically to reduce impacts. Bridging the gap from synthesis science to informed decision-making requires the novel analysis to be incorporated into a planning conversation. By embedding the Symphony analysis in the SeaSketch platform, we are able to give a broad set of participants the ability to sketch zoning plans, evaluate the cumulative impacts, compare hypothetical zoning scenarios to a baseline of impacts, and co-develop a marine spatial plan informed by sophisticated science.
