“…For instance, the fringe between the economic and the social approach is not well distinguished, leading to the frequent use of econometric methods to assess social preferences on ecosystem services. In other instances, the social approach is only implemented to assess cultural ecosystem services, disregarding the rest of the services (such as regulating, supporting, and provisioning) (Newton et al 2012;Plieninger et al 2013). The omission of the other types of services in the social valuation of ecosystem services might be due, among other reasons, to the expertise and amount of time that these methods require, and to the usual confusion between the category of socio-cultural ecosystem services [i.e., ''the nonmaterial benefits people obtain from ecosystems through spiritual enrichment, cognitive development, reflection, recreation, and aesthetic experiences '' (Millennium Ecosystem Assessment (MEA) 2005, p. 40] and the social approach of ecosystem services (which evaluates all ecosystem services).…”
