Although tourism is a major engine of economic growth, it also creates a burden hard to manage, and has a great impact on the conservation of the heritage. The project aims to reduce the impact of human activities (tourism-related ones) on cultural heritage, with a special focus on 2 kind of cultural destinations that can benefit from and be affected by mass tourism: Old towns & Sites of particular cultural heritage or archaeological interest for visitors, including UNESCO World Heritage Sites, so present in the MED territories. In that framework, HERIT-DATA plans to develop of a sustainable and responsible tourism management towards cultural heritage in MED regions, in particular by taking advantage of technology and innovation in management tools (Smart Cities), as well as other policy and social measures. The partners will develop, test and transfer a series of knowledge and solutions (Models, Strategy, Artificial Intelligence & Big Data based-on platform and App, etc.) in line with the current sectoral changes and characteristics of smart destinations, able to collect, generate, integrate and analyse information and transform it into behaviour changes, according to ICZM recommendations. The results will also contribute to decision-making processes from a holistic perspective and for all stakeholders: Planners (Public Administration & Tourism or Heritage Managing bodies); Visitors (coastal and cruise tourists visiting heritage sites), local stakeholders and host citizens.
