The International Congresses Hypogea / UIS 2015-2021

UIS International Union of Speleology is the world reference organization for the scientific speleological activities, formed in 1965, counting members from all continents, represented by a delegate from each country (this delegate acts as the representative of all the country's cavers and speleologists). An elected Bureau runs the affairs of the UIS between the once-every-four-years General Assembly meetings held at the International Congresses. The actual speleological work of the UIS is done by the members of its Commissions and Working Groups, which are open to everyone who is interested. The Commission on Artificial Cavities is a part of the Department of Scientific research at UIS. The updated members of the Commission belong from the following countries: Australia, Belgium, France, Great Britain, Ireland, Israel, Italy, Netherlands, Portugal, Russia, Turkey and United States of America
