Slovakia is renowned for its remarkable and rare natural beauty, abundant in natural resources with several noteworthy geological features. However, the protection of nature has primarily been understood as the protection of biodiversity in Slovakia. For the conservation of geological diversity and landforms, very little has been done. Geoconservation or the protection of geodiversity is being applied to specific places known as geosites, where significant earth elements (geological, paleontological, geomorphological, hydrological and pedological) are protected, preserved and managed. Most geosites benefit from existing protected areas. Their protection is random and does not result from the recognition of their values. As discussed in the paper, geotourism related activities can undoubtedly contribute to promoting the protection of geosites in protected areas. Besides, through a geotourism approach, geodiversity can obtain public attention and positively influence the state of protected areas by its activities. Such initiatives not only can improve the protection of geological sites but also can play a crucial role in sustainable tourism development.

Geotourism as a globally growing phenomenon is based on several principles where sustainability plays a key role. The value of an individual site of visitors’ interest (geosite, geomorphosite, or site of geological heritage—a primary point of interest in geotourism) may be expressed via specific assessment methods. However, recent geosite assessment methods are primarily focused on various aspects of geoheritage (e.g., location, scientific value, representativeness, etc.) and very low attention is paid to the majority of geotourism participants—people for whom the various geotourism products are introduced and offered. The geotourism development itself would not be possible without interest of tourists (visitors) in such places. Without the knowledge of relevant visitor data incorporated within the assessment, as discussed in this paper, such values, representing the result of the geosite assessment process, cannot be effectively utilized to help future geosite development and management activities related to overall (geo)tourism progress.

Geotourism is sustainable tourism form which is primarily based on the existence of geoheritage. Many research studies have been devoted to assessing geoheritage in last two decades, from various perspectives. Depending on the assessment methods and results, authors of such studies often refer to potential geotourism development based on specific geoheritage values. This paper, based on a study and analysis of relevant literature retrieved from WoS and Scopus databases, focuses on assessment criteria and their relevance to geotourism development for the general public. The results show that the absolute majority of assessment methods are probably of high importance for experts. However, in terms of effective application of the assessment results to sustainable geotourism development, different criteria should be used, including visual attractiveness, uniqueness, accessibility, safety, and the possibility of gaining knowledge. In this regard, extensive research is required on how geoheritage and its interpretation appeal to visitors, especially among the lay public.

The constant consumption of resources exerts pressure on the environment. In this sense, waste management has obtained increasing attention from the view of a circular economy. The European Union deals with these mentioned aspects, trying maintain long-term competitiveness and to provide sustainable development in accordance with all related environmental aspects. This paper focuses on the evaluation of the production of communal waste in 36 EU countries. The main aim is to evaluate the success of countries’ efforts to decrease waste production and increase recycling rates. The methodology used for the evaluation included data collected from the publicly available database Eurostat, consequent analyses and evaluation in the statistical software JMP 13 through regression, distribution, and cluster analysis, and the interpretation of the results. The results of the cluster analysis showed that despite clear EU waste management legislation, EU member states have significantly different waste management systems at the national level. However, generally, we could see positive correlation between the generation of waste and recycling rates. Although, Malta, Austria, Greece, and Norway recorded a decreasing level of waste recycling over the last several years, some countries (Slovakia, Poland, Czech Republic, Latvia, Lithuania) had significantly lower recycling rates accompanied by low landfill taxes. The evaluation of waste production and recycling can be used for government policy in the area of waste management, as well as for individual communities dealing with communal waste.

This study examines the application of Geographic Information Systems (GIS) in tourism planning and sustainable destination management, using Gelnica, Slovakia, as a case study. The research highlights a key challenge—the absence of systematic visitor data collection—which hinders tourism market analysis, demand assessment, and strategic decision-making. The study integrates alternative data sources, including the Google Places API, to address this gap to analyse Points of Interest (POIs) based on user-generated reviews, ratings, and spatial attributes. The methodological framework combines data acquisition, spatial analysis, and GIS-based visualisation, employing thematic and heat maps to assess tourism resources and visitor behaviour. The findings reveal critical spatial patterns and tourism dynamics, identifying high-demand zones and underutilised locations. Results underscore the potential of GIS to optimise tourism infrastructure, enhance visitor management, and inform evidence-based decision-making. This study advocates for systematically integrating GIS technologies with visitor monitoring and digital tools to improve destination competitiveness and sustainability. The proposed GIS-driven approach offers a scalable and transferable model for data-informed tourism planning in similar historic and environmentally sensitive regions.
