Ocean acidification and sea warming could harm unique Mediterranean habitats and species which are associated with important recreational ecosystem services. Luís Campos Rodrigues (ENT; ICTA/UAB) is the leading author of a study developed in the context of the European Union Project MedSeA (http://medsea-project.eu/). The study aimed at estimating recreational costs associated with a potential degradation of gorgonians communities and the higher abundance of stinging jellyfish at scuba diving areas. For that purpose, a Choice Experiment was developed for scuba divers at the Marine Protected Area of Medes Islands (Catalonia; NW Mediterranean). Estimates of welfare values include a cost of €60/dive for a scenario involving a local extinction of gorgonians, followed by a cost of €26/dive associated with a potential abundance of stinging jellyfish species.
