Gaia Exploration Club

Gaia Exploration Club Gaia Exploration Club (GEC) is a SEC-registered non-government organization devoted to the exploration, study, and conservation of the environment.

The Gaia Exploration Club was formed in 1996 as a SEC registered non-government organization by Mark Dia with the intention of finding like-minded individuals who wanted to do various outdoor sports activities such as caving, diving, hiking and rock climbing. The goal was to develop an organization devoted to the exploration, study and conservation of the environment. Initially having a few member

s, the group has now grown into a solid organization with caving projects in different parts of the country. The organization is composed of individuals with different expertise, all seeking to maximize their contribution to the ideals of the group and in the process discover their potential. From the vision of exploration and conservation, four subsections were formed – terra, sub-terra, hydro and anthro. Terra is the exploration of earth features and terrestrial flora and fauna. Sub-terra is the section devoted to the exploration of the caves and karst areas, pushing the frontiers of underground exploration including underwater cave systems. Hydro section is the exploration of water bodies and life within through SCUBA or through the use of kayaks. Anthro section is the study and exploration of human history and culture.

UNESCO Proclaims the International Day of Caves and Karst!

At today’s General Conference of UNESCO in Samarkand (12 November 2025), 13 September was officially proclaimed the International Day of Caves and Karst — a global recognition of the significance of the hidden world beneath our feet.
The initiative was proposed to UNESCO by the Republic of Slovenia, following the proposal of the International Union of Speleology (UIS), in close cooperation with the Slovenian National Commission for UNESCO, the Permanent Delegation of Slovenia to UNESCO, and the Karst Research Institute ZRC SAZU, where the UIS headquarters has been based in Postojna, Slovenia.
Caves and karst cover nearly one quarter of the Earth’s land surface and provide drinking water to over a billion people. They preserve unique subterranean biodiversity, geological archives, and invaluable cultural heritage. Yet, they remain among the least understood and most fragile ecosystems on our planet.
The International Day of Caves and Karst will help raise global awareness, promote research, education, and international cooperation in science, environmental protection, culture, and sustainable tourism.
The UIS warmly thanks all UNESCO Member States that supported the initiative, as well as the UNESCO scientific programmes (IGGP, MAB, IHP) and international partners including the International Science Council (ISC), IUCN, and more than 150 organizations worldwide that endorsed the proposal. Our sincere appreciation goes to the Slovenian National Commission for UNESCO and the Permanent Delegation of the Republic of Slovenia to UNESCO in Paris for their dedicated diplomatic efforts and continuous support.
From now on, September 13 will unite the global cave and karst community in celebrating and protecting these vital landscapes — for science, for nature, and for humanity.
Don’t forget, in 2026 we will celebrate the first ever International Day of Caves and Karst on 13 September!
Nadja Zupan Hajna, UIS Past President
