Abstract: Two case studies will be presented to illustrate the possibilities and challenges in providing economic estimates of the benefits provided by the marine and coastal cultural ecosystem services (ES), i.e. recreational use values and the non-use values (existence and bequest values) of preserving coastal and marine biodiversity.
In addition to providing monetary estimates for policy use, these studies also address important methodological challenges in ES valuation like the temporal stability of peoples preferences for coastal and marine ES, regional differences in preferences, definition of the “affected” population” to aggregate benefits over, scope effects (i.e. are people willing to pay more to preserve more CWC/avoid larger oil spills and ES damages), linking oil spill dispersion models and scientists´expert estimates of ES damages, and how to present temporal losses in complex ES in ways people can understand in stated preference surveys.
