Abstract
The Dominican Republic is the most visited insular tourist destination in the Caribbean, being its beaches its main attractiveness. This tourism generates 37% of the total revenues of the country, concentrated in coastal regions. As a result of this pressure, the coastal ecosystems are threatened by the increasing tourist development. Parameters such as site and dune morphology, beach condition, surface character of the seaward 200 m of the dune, pressure of use and recent protection measures make good regional comparison of beach-dune systems. A checklist was developed to calculate Vulnerability Index (VI) and Management Measures (MM) in 99 beach-dune systems of Dominican Republic allowing to identify and prioritize the different pressures. This method of study, associated with Geographical Information Systems (GIS), give more visibility to beach-dunes conditions, and by this facilitate the necessary decisions in the context of a sustainable management of coastal areas. The results indicate that the risk of beach erosion and degradation is directly related to the pressure of use of the coastal area.
