Abstract: Agroecosystems are anthropised ecosystems where human activities, mainly agricultural practices, affect the innate functioning, leading to the provision of agroecosystem services (AES) and disservices (AEDS). This study presents a novel and integrated economic valuation of the AES and AEDS provided in a water-scarce Mediterranean area (south-eastern Spain), using a discrete choice experiment. The results reveal the social demand for AES and the disutility of AEDS, as well as the non-linearity in marginal utility for some of these AES and AEDS. Food provision, temperature regulation, leisure and recreation and biodiversity are socially perceived as AES. The water supply for irrigation switches between AES and AEDS depending on its provision level, while groundwater pollution is conceived as one of the AEDS. The integrated non-market value of AES and AEDS reaches 794 €/ha/year for the entire agroecosystem. This work provides guidelines for policy makers in the design of socially supported agricultural policies.
