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.

The paper focuses on the evaluation of some aspects of the spatial organization of economic development of regions in the V4 countries after their accession to the EU. It focuses on the confirmation or confutation of the application of two principles of spatial organization based on the context of polarization theories, namely the polarity between western and eastern regions (i.e. the West–East gradient) and the polarity between the capital and other regions of the country (i.e. the national metropolitan gradient) at national and supranational levels. In the evaluation of the spatial polarity, the remoteness of various regions of the V4 countries from the economic core area (the Blue Banana, respectively the capital of the country) acts as the independent variable, whereby two economic indicators, i.e. the average monthly wage and the unemployment rate were chosen as the dependent variables. The analysis showed that on the supranational scale of the research in the monitored period, the increase of spatial polarisation was recorded. The increasing role of the West–East gradient and declining role of the national metropolitan gradient in the dynamics of spatial polarity has also been confirmed. The analysis has not confirmed the scale shift of polarity according to the West–East gradient to the national level, but at the same time it has pointed out the significant influence of the national metropolitan gradient in Slovakia, the Czech Republic and Hungary at this assessment level.

The presented article is focused on a spatial analysis and identification of high and medium risk areas and their impact on potential for geotourism development in the Central Spiš region in Slovakia. To achieve this goal, we used a combination of two methods: the multi-hazard assessment method and the quantitative Geosite Assessment Model. The research results show that the geosites with the highest potential for the development of geotourism are also located in the low treat zone. These are mainly GS₉ adit Pavol (overall point value 16.25), GS₁ adit Rochus (15.25) and GS₈ adit Peter (14.00). On the other hand, geosites with a low point value for the development of geotourism, such as GS₁₀ sinkhole Baniská (7.75) and GS₅ tailings impoundment Markušovce (10.50), are located in the high treat zone. The obtained results show that even in the significantly anthropogenically burdened and economically underdeveloped post-mining landscape of the studied area, it is possible to identify positive impulses for further development. This concerns in particular the use of evaluated geosites in geotourism, with the aim of simultaneously supporting the protection of local cultural heritage, the natural environment and the socioeconomic development of the local community.

Presented paper deals with the issues of regional development and regional disparities in Slovakia in the years 2001-2014. Levelling respectively increase of regional disparities was evaluated through a set of 13 socio-economic indicators (gross birth rate, average monthly wage, monthly labour costs per employee, employment rate, unemployment rate, net monthly income and expenses per capita, completed dwellings, creation of GDP, labour productivity per employee in industry and construction, number of organizations focused on generating profit and number of freelancers) which were used in the territorial units at the level of self-governing regions of the Slovak Republic (NUTS III level). In terms of the evaluation and comparison of regional disparities were used the Gini coefficient and the coefficient of variation for mutual comparison and validation of divergent or convergent tendencies of regional disparities in Slovakia.

The topical issues for elaboration of new approaches to grow English oak (Quercus robur L.) seedlings with the purpose to establish sustainable plantations in forest-steppe Ukraine. The goal of the research is to elaborate a technology for growing the containerized seedlings of English oak. Oaks are among the most common tree species found throughout the world. Throughout history, oaks have provided humans and wildlife with shelter, and food. However Ukrainian forests face multiple natural and anthropogenic pressures. Climate change generates a particular threat for Ukrainian forests and stability of agroforestry landscapes. This paper considers the impacts of expected climate change on vulnerability of Ukrainian forests, especially for oaks. In response to forest depletion, stricter forest management practices emerged to replant, protect and maintain forest cover and the multi-functionality of forests in terms of wood production. Even though oaks have wide ecological amplitudes of suitable growing conditions, Ukrainian forests dominated by oaks often fail to regenerate naturally. In this regard, it is necessary to increase the cultivation of crops in containers. Field germination of oak seedlings in containers with different substrate composition was identified in the case study in the conditions of Ukrainian Left-bank Forest-Steppe. The height and diameter values of the seedlings were investigated and summarized including the influence of the root ball substrate composition. We tested different compositions of the substrate containing low-land peat, which is rich in nutrients and mixtures with different ratios of soil, humus and sawdust. The advantage over the control in germination ability, survival and condition has been experimentally proved for variants with the use of peat in the substrate and, to a large extent, for the variant with the use of soil, humus and sawdust. Among tested substrates, the peat-containing variant with equal portions of dark gray wooded middle loamy soil and peat (peat:soil = 1:1) and the variant of the three-component mixture soil:humus:sawdust = 4:2:1 are the most balanced in the basic soil parameters (acidity and nutrient content). In the same time they are the best among the studied ones for the productive growing of English oak seedlings. The use of containerized planting stock allowed foresters not only to significantly extend the terms of forest planting, which is particularly topical for Ukraine, but also to increase the root-taking of planting stock up to nearly 100% in forest-cultivated areas.
