The development of urbanisation is linked to qualitative and quantitative changes in the landscape and its components aimed at strengthening economic, administrative and cultural-social functions, which are associated with ever-increasing pressures on ecosystems and their individual components. These pressures are subject to various factors—socio-economic, political, environ-mental, etc. In this paper, we present an evaluation of the environmental impacts of the development of urbanisation in Slovakia. Independent Slovakia belongs to the young European states. The communist period lasted from 1948 to 1989. The character of landscape, the quality of the environment and also the degree of anthropisation of territory were dependent on a centrally managed economy. Urbanisation changes began to manifest themselves rapidly after 2000, when the economy was transformed and Slovakia was preparing to join the European Union (Slovakia joined the European Union in 2004). The transformation from central planning into a market economy was the basis of the changes, which was conditioned following strong pressure of investors on the landscape, the construction of technological parks, shopping and logistics centres and transport infrastructure and the construction of residential complexes. According to the European Environment Agency’s study on urban sprawl between the mid-1950s and the end of the 1990s, industry, commercial and transport services have grown at a significant rate and the residential areas at a moderate rate in Slovakia. On the other hand, Slovakia has areas where urbanisation has the opposite trend. Rural settlements are abandoned as well as large areas of agricultural land. The character of land use has fundamentally changed over the past 20 years. These changes not only have a spatial dimension but are associated with the emergence of various environmental problems. The paper deals with the impacts of anthropisation and industrialisation of Slovakia after 2000. The anthropisation process in Slovakia was determined through data processed in GIS and also through the statistical data representing land use. Based on the ecological significance of land use elements, the degree of anthropisation in Slovakiawas calculated.

This contribution deals with the use of data obtained from Landsat 8 satellite imaging to identify surface temperature variability in the example of the city of Bratislava, with an emphasis on identifying hotspots outside the built-up area, for example, on agricultural land—locations which are part of the European Network of Protected Areas. Surface temperature variability is presented in two time periods, on the daytime image taken on 26 July 2021 and on the nighttime image from 28 June 2021. Surface temperature is projected in a profile cut of the area. It vertically illustrates the temperatures of individual types of surfaces. Surfaces are classified by Urban Atlas classes. Areas reflecting the spatial distribution of the residential development in the city of Bratislava have been identified by satellite images in the studied area, and they represent a phenomenon of the urban heat island. Such areas were also identified outside the built-up area, in agricultural areas. The results of our research show that it is important to deal with UHI outside the built-up areas of cities and to orient the attention the territory planning and also to the proposal of measures for the management of these areas. Especially if these areas also include territories of the European system of protected areas, as it is in the case of Bratislava city (e.g., SPA029 Sysľovské polia). The results of reducing the impacts of climate change in cities concern not only the residents. In spatial planning, it is also necessary to address the management of non-built-up areas—localities with a quasi-natural character (e.g., areas with diverse vegetation cover). In order to recognize UHI within residential areas, it is essential to identify areas with significant differences between daytime and nighttime surface temperatures. Large differences between night and daytime surface temperatures can be seen in areas outside the built-up area in Bratislava on arable land where the difference is up to 8.0 °C (in the continuous housing class where the proportion of impermeable surfaces is higher than 80% with a temperature difference of 7.6 °C). Identification of overheated surfaces in the territory makes an important basis for modification of the landscape management and management of nature protection areas. It is important to propose measures related to the reduction in the negative impacts of climate change on the landscape and biodiversity.

Due to the falling water level in the Aral Sea and Muynak Lake, the content of salts dissolved in the water has gradually increased, and toxic elements have been deposited at the lake’s bottom and subsequently washed into the Aral region by the river. Bacteria, archaea and fungi are crucial for the cycling of several important inorganic nutrients in soils. From 15 genera and 31 species of recovered microscopic filamentous fungi, a big group was melanized, of which most of them were also phytopathogenic. The second group consisted of keratinophilic species. Isolated bacteria mainly included members of the genera Arthrobacter, Bacillus, Massilia, Rhodococcus and Nocardiopsis. High-throughput sequencing analysis permitted a better view of the mycobiome and prokaryotic communities (comprising archaea). The cultivation and sequencing approaches were shown to be complementary. The aim of the work was to identify soil microorganisms, including the order Halobacteriales, and to discover the differences in species diversity depending on soil salinity and the presence of PTEs in soil.
