International Conference "Man and karst" will be organized this year in Livno, on the edge of one of the most beautiful karst polje in the Dinarides by the Center for Karst and Speleology, Sarajevo, Bosnia and Herzegovina, University of Zadar, Department of Geography, Zadar, Croatia and University of Montenegro, Faculty of Philosophy, Nikšić, Montenegro. As before, the goal is to continue affirmation of karst potentials and protection of karst ecosystems and its karstic heritage. This is intended to be achieved through better connections and meeting people interested in karst issues and exchanging scientific news. We would also like to get the attention of attendees and report works dealing with changes in karst environments and landscapes, which may be the result of natural processes, and in particular the impact of man.
