This study developed a new integrated assessment method for sandy beaches, using three recreational Italian beaches as case study, with the purpose of obtaining their economic value. The method was based on a geomorphological assessment of the beaches and a carrying capacity evaluation; an economic analysis through the elicitation of the willingness to pay (WTP); a social assessment of beachgoers’ attitude and opinion. For the selected beaches, which differed for typology, location, shape, level of urbanization and tourism, we identified the available surfaces for recreational uses trough the observation of satellite images. WTP results indicate that respondents would be willing to pay a contribution from 9 to 15€ per season. WTP is principally positive correlated with some variables like beach frequentation, residence in the localities, available services on the beach. The value of the selected beaches was calculated multiplying the sustainable carrying capacity of each site with their related maximum WTP. It was found that the values of the beaches varied from more than 50M€/season at a popular urban beach to 1M€/season at a remote natural beach. The comparison of beach valuation and investments made by managers of the beaches show a gap. Therefore, the huge non-market value of these beaches might need decision-makers to guarantee continuous beach restoration measures.
