Marine Ecosystem Services

Marine ecosystem services in Nordic marine waters and the Baltic Sea - possibilities for valuation

image of Marine Ecosystem Services

Marine Ecosystem Services (MARECOS) is an interdisciplinary study that provides relevant information for national, Nordic and international ecosystem services assessments and valuation in the implementation of marine policy.

This report aims to provide suggestions on how ecosystem condition assessments, being based on the Marine Strategy Framework Directive (MSFD), and the HELCOM indicator based assessments for the Baltic Sea, could be used for the assessment of ecosystem services.

By describing the potentials of linking data and knowledge describing the status of marine ecosystems and water quality to the values of the services and goods provided, the report offers useful information for policy and decision makers in the domain of the marine and aquatic policies around the Baltic and in the Nordic countries.



Literature study on the value of marine ecosystem services

The focus of this chapter is to describe the current knowledge of valuing marine ecosystem services. This is done by linking recent valuation studies and the results to environmental indicators, namely the descriptors of good environmental status (GES) in the Marine Strategy Framework Directive (MSFD) described in Chapter 5. The results are also linked to the HELCOM CORESET indicators. The valuation studies are assessed and described with reference to spatial explicitness, marginality, double-counting, and nonlinearities and threshold effects, as these factors are important determinants of the validity of the studies in an ES setting. The possibilities for benefit transfer and aggregation of values across larger geographic scales are also assessed.
