3 Assess and value

Navigation Arrows Previous NextPreviousNext

Objectives of this section
This section develops the presentation of three sets of methodologies which may be implemented and/or selected during the triage process: ecological, social and economic methods and offers a toolbox for marine ecosystem services assessment and valuation.

Numerous methods can be used to assess marine ecosystem services. Basically, these methods belong to natural sciences or social sciences, and for some of them try to cross concepts and principles from both realms. A systematic review of the ecosystem services assessment methods has been recently carried out by the US Environmental Protection Agency [EPA, 2009].

This section of the e-learning module develops the presentation of the sets of methodologies which have been implemented in the VALMER case study sites. These sets of methodologies include: ecological assessment methods (habitats-functions-services relationship assessment, sensitivity assessment), social sciences methods (interviews, surveys, multi-criteria analysis), economic methods (transport costs, choice experiment, ecosystem accounting, Bayesian belief networks) and cross-methods (INVEST, system dynamic modelling).
