Mountain depopulation is a worldwide phenomenon observed in all continents. It has varied socio-economic reasons; among others, the low profitability of traditional agriculture, the better job possibilities and the higher level of services in urban settlements. However, it is often recognized that depopulation is related to natural factors such as elevation, slope or lithology. It is also observed that protected areas are frequently established in depopulated mountain regions. Their primary aim is the conservation of nature, but they may help tourism development as well. Tourism, in turn, may slow down or even reverse the process of depopulation. In this study, we investigate the impact of topographic and lithologic factors, namely of karst settings, on mountain demographic processes and the relationship of protected areas and tourism through the example of the northern part of Zlatibor District (Western Serbia). The study area is characterized by mountains and hills at elevations from 200 to 1600 m a.s.l. Our aim is to find GIS-based statistical relationships between topographic, lithologic factors and demographic characteristics. In this area, mountain depopulation started after WWII, and we proved that this process was strongly controlled by topographic factors. The higher and more dissected the area, the more significant is the decrease of the population and the more advanced is the ageing. As a result, population density contrasts are much more pronounced now than 70 years ago. After WWII, depopulation and ageing became gradually more serious on karstic terrains than on non-karst. However, by using compound topographic and lithologic types, we proved that it is not the effect of karst, but the effect of topography. The flow of population from hills and mountains to valleys and basins are closely related to the restructuring of the economic sectors. At present, for the study area, the development of tourism is unequivocally nature-based and connected to protected areas, namely to Tara National Park, Zlatibor Nature Park and Šargan-Mokra Gora Nature Park. In this paper, we also demonstrate how lithology influences tourism possibilities. The leading role of Zlatibor in tourism development is largely thanks to its favourable position on a main transit route.

By the example of Tara National Park (NP), we present how the geoheritage can and should be presented in a NP where the primary role is played by biology. Tara NP has a rich geoheritage, especially its karst phenomena, which include gorges (e.g. the 1000-m-deep Drina Gorge), plateaus with dolines, dry valleys, and uvalas as well as springs and travertines. In addition, ophiolites also enrich the geoheritage; hence, the area has a high geodiversity. Large reservoirs of the territory provide an opportunity to study the anthropogenic impact on hydrology and geomorphology. After presenting the geoheritage elements of the area, we examine the views and knowledge of local people and visitors about karst and geotourism with the help of a questionnaire survey. The results show that local residents support the further development of tourism, but geotourism is a rather new concept for them. On the contrary, tourists are more familiar with geotourism. Among the development perspectives, tourists support those that involve only minor environmental changes, that is in agreement with NP policy. Finally, we formulate some suggestions about geotourism development in the area. First, we outline some plans for new geo-educational trails and viewpoints. Second, we highlight the possibility to increase the geo-content of some already existing programs (e.g. boat tours). Third, we emphasize that geotourism of Tara should be connected to neighbouring areas. A new geopark is already under planning, which would include the area of Tara NP as well.

This paper represents a case study examining attitudes of various stakeholders about Tara National Park (NP) (Serbia), identifying also the factors that shape these attitudes. The survey method was applied to a sample of 405 respondents (197 community members and 208 visitors). In addition, 15 interviews with specific key actors (NP executives and local key persons) were performed. The research confirmed the presence of different types of conflicts among stakeholders, mostly between the NP and the local population (primarily farmers) associated with land use in agriculture and the ban on the construction of facilities. The community recognizes tourism as the highest priority, unlike the NP leaders and visitors, who emphasize protection and conservation (especially biodiversity) as the primary goals of future NP development. The opinions of the local population are divided concerning support for the existence of the NP and the importance of it as a part of the national heritage. Most of them do not recognize the economic benefits resulting from the proclamation of the NP and do not see themselves as participants in the decision-making process. The findings also reveal that visitors strongly support tourism development and activities following the principles of nature protection. This category of respondents is only partly affected by the fact that this area has been declared a NP. The analysis shows that certain socioeconomic factors considerably influence the opinions of both community and visitors. Results suggest that future actions should be aimed at improving the coordination of various stakeholders, especially the NP and the community, through different social mobilization activities. Stimulating small businesses and providing incentives for agriculture and nature tourism development could be a useful step forward.
