Message de Nadja Zupan Hajna, ancien President de l'Union Internationale de Spéléologie (UIS) :
I am very pleased to share that the UNESCO Executive Board has today adopted the decision on the International Day of Caves and Karst (IDCK) — co-sponsored by 59 countries! The final proclamation will take place at the UNESCO General Conference this November in Uzbekistan. Let’s keep our fingers crossed for a positive outcome and for global recognition of caves and karst!October 9, 2025
The final decision of UNESCO will be made in just 3 weels :)
