KnowSeas provides comprehensive scientific knowledge and practical guidance for the sustainable development of Europe's regional seas through the application of the Ecosystem Approach. The project aims to improve understanding of human impacts on marine environments, develop models for systems analysis, and address wicked problems in fisheries and coastal governance.

“Wicked” and “Tame” Problems “Tame” problem can be solved by careful rules-based or consensus management First order “fixes” Clear solutions no clear solution; there will be winners and losers “Wicked” problem involves moral judgements and value-based decisions: governance.

Regime shifts in all systems Thorsten Blenckner, Andrew Kenny, Peter Kershaw, Alberto Barausse, Georgi Daskalov, Maciej Tomczak, Alison Gilbert
Results- Drivers of regime shifts • Methods: • Regression Analysis on de-trended time-series of abiotic drivers vs. PC1s: Generalized Additive Model (GAM) • The most parsimonious model was identified using the Akaike Information Criterion (AIC)

THE PUBLIC VIEW KnowSeas Social Science
Conclusions (1) Recognition of the sea as a complex coupled social ecological system requiring an ecosystem approach to management is an important policy development Our perceptions of the environment and human values are critically important for its management Complexity is difficult to grasp, whether a scientist or a decision maker
Conclusions (2) Adaptive management is one towards an ecosystem approach but there are pitfalls and risks. We should be planning for the next adaptive cycle of the MSFD Serious mismatches of temporal and spatial policy and legislation reflect sectoral silo thinking; big picture science helps to maintain an overall vision and context for the MSFD and GES Beautiful
Conclusions so far • Severe non-linear changes ”regimes are detected” in the three regional seas • Potential drivers of such changes are: • Climate (North Sea, Baltic Sea) • Fishing pressure (Baltic Sea, Adriatic Sea) • Nutrient loading (Adriatic Sea)
