• Resumen

  • Coastal ecosystems provide key services, but human activities and natural phenomena such as coastal erosion can strongly affect them. These changes can induce severe ecological and economic damages. This study aims to evaluate temporal changes in a protected area (Regional Park of Maremma, Southern Tuscany, Italy) in terms of both ecological and economical damage associated with ecosystem services loss observed over the period 2001–2014. Studies were performed using remote sensing as well as field verification for more critical habitat types. Results show an overall reduction of the habitat in flooded areas. During the study period total Ecosystem Services Values (ESV) decreased by more than 13% and the major contributor to that changes is loss of wetlands (net reduction of about 4.3 M US$/y), not directly beach erosion. Although this study proposes a first order approximation in terms of ESVs of considered biomes, these values are set to increase in the near future as knowledge and technologies improve. Therefore, wetlands management plans are crucial in this context, and could have much more significant effects on ecosystem efficiency and resources for future generations than beach erosion prevention.
