The indicator on recreational and educational services of Mediterranean wetlands (RES-MW), developed by the MWO and the Mediterranean Agronomic Institute of Montpellier (IAMM) during the period 2011-2016, is intended to measure the human and social impacts that wetlands generate on the visitors to these ecosystems. The logic behind the indicator is that a natural capital (wetlands), when made accessible through a constructed capital (infrastructures and services provided by managers), generates an impact on human and social capitals (visitors). The study was carried out in 27 Mediterranean wetlands spread in 10 countries in different sub-regions. In each site, 150 visitors were interviewed, or 4050 persons in total, with 3717 validated questionnaires. The large majority of visitors interviewed (61%) were nationals of the countries involved in the study. The synthesis for decision-makers includes a series of recommendations to increase the positive impacts on visitors to wetland sites
