Human Footprints in the Karst Landscape: The Influence of Lime Production on the Landscape of the Northern Dalmatian Islands (Croatia)

Throughout history, the production of lime on the Croatian islands, which are mostly made of limestone and dolomite, has been an important economic activity. In the northern Dalmatian islands, which are centrally positioned on the northeastern Adriatic coast, lime was produced for local needs, but also for the purposes of construction in the nearby cities of Zadar and Šibenik. On the basis of research into various written and cartographic archival sources relating to spatial data, in addition to the results of field research, various traces of lime production have been found in the landscape of the northern Dalmatian islands. Indications of this activity in the insular karst are visible in anthropogenic forms of insular relief (lime kilns, small quarries, stone deposits) and in degraded forms of Mediterranean vegetation. This activity has also left its mark on the linguistic landscape in the form of toponyms, indicating that lime kilns were an important part of the cultural landscape.

Analysis of Attendance and Speleotourism Potential of Accessible Caves in Karst Landscape of Slovakia

Caves represent natural phenomena that have been used by man since ancient times, first as a refuge and dwelling, and later as objects of research and tourism. In the karst landscape of Slovak Republic in Central Europe, more than 7000 caves are registered in a relatively small area, of which 18 are open to the public. This paper deals with the analysis of the speleotourism potential of 12 of these caves, administered by the Slovak Caves Administration. Based on the obtained data, we first evaluate the number of visitors in 2010–2019. Using a public opinion survey among visitors, we then evaluate the individual indicators of quality and each cave’s resulting potential. We use a modified standardization methodology and standardization of individual evaluation criteria weights for individual evaluation indicators. The resulting values of the potential of caves for speleotourism point to the great importance of these sites for domestic and foreign tourism and the protection of nature and landscape, as 5 of these caves have been part of the UNESCO World Natural and Cultural Heritage List since 1995.

Communication Networks as a Catalyst for Holistic Sustainability on Karst Landscapes

Equitable access to communication and education is a key aspect in ensuring sustainability in any natural area. Karst landscapes are especially susceptible to environmental degradation from natural and anthropogenic forces and can benefit from sustainable economic, social, and environmental practices. This study took place in Phong Nha-Kẻ Bàng National Park (PN-KB), a highly developed karst landscape in central Vietnam. Through in-depth interviews, this study explored the ways in which formal and informal communication networks between the diverse stakeholders living within the park can be used to better protect the landscape from further degradation. The research findings suggest that a lack of consistent communication between PN-KB’s residents, rangers, and governing officials has left the landscape vulnerable to extensive degradation and susceptible to catastrophic climatic events. Increasing communication between the stakeholder groups within the park will bolster economic opportunity and ensure equitable access to information and resources, both of which will promote sustainable practices and karst landscape protection.
