Patrimoine géologique et géomorphologique : base pour le géotourisme et la création d un géoparc UNESCO dans le Dahar (Sud-est tunisien)

The presence of geoheritage of international value is the basis of any candidature as a UNESCO Global Geopark. Within the framework of the elaboration of a roadmap for the creation of a UNESCO Global Geopark in South-East Tunisia, a geological and geomorphological study was carried out. The selected geoheritage can be divided into two main families : palaeontological and sedimentological sites, which provide complete documentation of the opening of the southern Tethysian margin, from the Triassic to the Cretaceous, and geomorphological and landscape sites (cultural geomorphosites), which offer an exceptional range of adaptations of human societies to the morphoclimatic context. This analysis of the geoheritage is the basis for the implementation of a strategy of geoconservation, geotouristic enhancement and, ultimately, the creation of a geopark in the Djebel Dahar. It demonstrates the importance of the interrelationships between the cultural, tangible and intangible, heritage and the geomorphological context.
