The International Day of Caves and Karst (IDCK), officially proclaimed by UNESCO, is celebrated on 13 September (https://www.caveskarstday.org/).
Caves and karst landscapes cover nearly one quarter of the Earth’s surface and provide essential ecosystem services, including water supplies for over a billion people, unique biodiversity, and valuable cultural and scientific heritage.
