September 13, IYCK towards IDCK

On September 13, 2021, we had the honor of presenting the fascinating world of caves and karst at UNESCO Headquarters in Paris. This groundbreaking event, which took place as part of the International Year of Caves and Karst (IYCK), laid the foundation for the UIS initiative to proclaim September 13 as the International Day of Caves and Karst (IDCK). Let us continue to raise awareness and appreciation for these natural wonders that play such an important role in our world! Nadja Zupan Hajna UIS President

Call for support for the IDCK proclamation

The International Union of Speleology (UIS), in cooperation with the Slovenian National Commission for UNESCO, is actively promoting the establishment of the International Day of Caves and Karst (IDCK – September 13). Why September 13th? Because there is no other international day on this date, because no nationality is favored and because on this day in 2021 caves and karst were presented to UNESCO for the first time (although the UIS was founded on September 16), and because UNESCO representatives like the idea. You can read more about the UIS proposal in a new UIS Bulletin 66-1. It does not matter if your country or region already celebrates a specific cave day other than the International Day of Caves and Karst proposed here, it's just important that the public learns…

International Journal of Speleology – call for papers

The International Journal of Speleology, the official journal of the Union Internationale de Spéléologie, is excited to announce a call for papers for a Special Issue on Cave monitoring: the good, the bad, and the nice. Understanding the dynamics of cave environments requires intensive and extensive measurements and monitoring of the physical, chemical, geomorphological, and hydrological parameters, encompassing all features of the caves (geology, hydrology, morphology, air, water, biota, and human impact). Technological advances have shifted observations from sporadic to continuous monitoring, albeit methods vary significantly in frequency, precision, accuracy and duration. Historically, measurements were taken on a “need to know” basis, often focusing on specific parameters like air temperature, while overlooking potentially crucial factors such as CO2 levels or water, soil or rock temperature. Additionally, the lack of affordable…
