Besides the usual editor, Geologia Croatica also has a guest editor Dr. Ognjen Bonacci. He has been appointed guest editor for this volume since he was the scientifi c organizer of the international interdisciplinary con- ference Sustainability of the karst environment – Dinaric karst and other karst regions, September 23−26, 2009. The conference was organized by the Centre for Karst Gospić, and was held at the spectacular Plitvice Lakes (UNESCO World Heritage Site), Croatia. The objective of this international conference was to provide theoretical and practical contributions to the concept of sustainable development in karst regions, with specifi c emphasis on the experiences from the Dinaric karst region. Karst landscapes, in which dissolution of bedrock by water is the dominant process, characterise almost 20% of the con- tinents and more than a quarter of the Earth’s population lives on or near karst areas (FORD & WILLIAMS, 2007). Typi- cal karst topography is essentially related to subterranean drainage and therefore geomorphology and hydrology are closely interrelated. The Dinaric karst stretches the length of the eastern coast of the Adriatic from the Bay of Trieste in the north to the Drin River in the south. This karst area is some 600 km in length, and up to 200 km in width. However, karst landscapes are present in many parts of the world, but most of the time these areas are shaped by a multitude of processes. The karst landscape is a unique geological envi- ronment that extends not only on the surface but also under- ground, in a continuum of habitats and geo-ecosystems that still wait to be discovered and studied. More than eighty presentations and posters were pre- sented at the conference, and nine papers originated from presentations at the conference dealing with geological themes. All contributions have passed the regular reviewing procedure, since this is an ordinary volume of our journal Geologia Croatica although it is predominantly devoted to karst issues. Themes covered range from the evolution of caves, to understanding the hydrology of karst, and chal- lenges to sustainability in karst terrains. Sustainable devel- opment of surface and subterranean water resources in karst, and the overall karst environment has been threatened by current climate change and climate variability in combina- tion with anthropogenic impacts. Interdisciplinary studies are imperative in order to establish the possible consequences of such impacts and to fi nd practical solutions to protect karst systems. After the “karstic” papers, there are three other in- teresting contributions spanning palaeontological to geo- chemical issues. REFERENCES FORD, D. & WILLIAMS, P.
