National Environmental Research Institute MARE: Management perspective HELCOM MONAS - member of the MARE board Marine Convention focusing on the state and development in both the open sea and coastal water Can MARE give advice on measures to be taken (catchment and the sea) to: –fulfil the 50% reduction target on nutrient loading –fulfil the future ecological quality objectives (EcoQO’s) Can MARE be used presenting and assessing the results of HELCOM monitoring programmes?

National Environmental Research Institute Decisions taken in HELCOM are based on common agreement - no “Directives” or “laws” Focus on measures within the HELCOM catchment, but measures on ship traffic, emissions outside HELCOM catchment, dredging etc. are also important MARE seems unique by combining measures, economy, catchment and state/development in the sea, with a ecosystem, holistic and a large scale approach There are strong requirements to a system that set up priorities on measures and costs between countries

National Environmental Research Institute Important to give clear messages as: –NEST is a decision support system - not a decision system –NEST provides overall “average” solutions both on measures and for the state in the Baltic Sea - not details on how and where! –state in coastal areas are mainly dependent on local inputs - other information required! Threat: results from NEST could be used as an excuse for doing nothing!

National Environmental Research Institute Requirements to MARE: –general acceptance by scientists and decision makers in the countries - recommended/used in many countries: not a “Swedish” model –open system: possible to link with/include national detailed models, open for developing NEST in countries –overall acceptance of the applied methodology: important to develop the catchment and economical parts of NEST –general acceptance of applied assumptions –input data accepted/possible to change –agreement on economical functions and results –included more ecological target variables (EcoQO’s) –provide time lags, uncertainties, probability

National Environmental Research Institute –easy available and good documentation –easy and fast to use for both scientists and managers –easy to make alternative scenarios –results from NEST: realistic, simple, easy to explain –don’t allow unrealistic scenario and solutions –usable in relation to the WFD and EU Marine Strategy –free of charge –involve local scientists and decision makers in further development and institutionalisation of NEST –institutionalisation should ensure that the system is updated and developed in future
