The assessment and mapping of ecosystem services (ES) has become an increasingly important instrument for environmental management and conservation priority-setting. As such, this practice can be used in ecosystembased Marine Spatial Planning (MSP). MSP is recognized as an opportunity to achieve socioeconomic and ecological goals simultaneously, to suggest solutions for sustainable management of marine environment and marine areas for conservation purposes. Our methodological approach aims at producing relevant scientific knowledge for prioritizing marine conservation and sustainable management actions, to be used in MSP and marine management.
