HRVATSKI GEOLOŠKI INSTITUT CROATIAN GEOLOGICAL SURVEY Potential geopark Vis archipelago (Central Adriatic, Croatia) – sustainable development of world-class geotourism based on natural resources Tvrtko KORBAR1, Mirko BELAK1, Nikola BELIĆ1 , Staša BOROVIĆ1, Jakša BOŢANIĆ2, Izidora MARKOVIĆ VUKADIN3, Josip TERZIĆ1 1 Croatian Geological Survey, Zagreb, CROATIA [email protected] 2 Ribarska 10, Komiţa, Vis Island, CROATIA [email protected] 3 Institute for tourism, Vrhovec 5, HR-10000, Zagreb, CROATIA [email protected] Mediterranean Islands Conference: MIC - Vis, 21-24, September 2016 HRVATSKI GEOLOŠKI INSTITUT CROATIAN GEOLOGICAL SURVEY Central Adriatic (northern Mediterranean) Vis island archipelago (Croatia) encompasses the islands of Vis, Biševo, Brusnik, St. Andrija, Jabuka and Palagruža, along with many islets and scars. HRVATSKI GEOLOŠKI INSTITUT CROATIAN GEOLOGICAL SURVEY HIGHLIGHTS • the island of Vis has limited fresh-water supply that is completely predisposed by unique geological structure; • the archipelago deserves the highest level of protection and promotion as an extraordinary geoheritage that could be used for world-class sustainable tourism; • We propose a cooperation with local and regional authorities for an expert-based project for development of sustainable tourism; • geotourism has tendencies to extend out of crowded main season and attracts mostly environment-friendly tourists. • final goal: Geopark Vis - an excellent opportunity for inhabitants to organize the highest level of sustainable development in future. HRVATSKI GEOLOŠKI INSTITUT CROATIAN GEOLOGICAL SURVEY New geological map revealed that Vis archipelago is characterized by the most diversified natural geoheritage in the region, relative to its size.
