The paper deals with the possibilities of further use of environmentally degraded and polluted areas on the example of (mining and industrial) activities residues in the Central Spiš region in eastern Slovakia. On the example of the Slovinky mining tailing pond, the Markušovce mining tailing pond, and two mining dumps in Rudňany, we deal with the analysis of their condition in terms of heavy metal content, as well as the real and potential alternative use of these sites. Data were collected using field trips and field research in sediment sampling in all localities and by preparing a questionnaire for opinion polls. The content of heavy metals from all four places, the results of field trips, and the questionnaire were analyzed. The article points out the current state of these objects in terms of their load with heavy metals and considers their possible alternative uses, especially in terms of geotourism or education. The implementation of geotourism in the studied sites brings along benefits, not only for visitors and students, but also has a positive impact on sites themselves and on the local community. The results of such analyses should also serve as a basis (starting point) in planning the renewal and further development of such areas.
Region of Middle Spiš is among the most environmentally burdened areas in Slovakia. It is the result of a long tradition of industry and mining in the region. Rich deposits of copper and iron ores in the Slovak Ore Mountains necessitated the expansion of mining and metallurgical activities in the region of Middle Spiš. Mining activity and the bulk of the industrial activity in the area was closed early 90s of the 20th century. Centuries-long mining and industrial activities had and continues to have negative effects on all components of the environment, which is among the environmentally degraded and heavily burdened. The paper deals with the analysis of the quality and the environmental load of soils and water impacts of mining and industrial activities. The main aim of the articles the analysis of heavy metals of the sample in the soils and water and their comparison with the results during active mining and industrial operation. Our aim is to try to point out on the continue contamination of selected elements of the environment.
Urbanization, increasing road networks, agricultural intensification, and land abandonment are widespread land change processes found in most European landscapes. As land changes affect animal species and their populations, there is a need to evaluate the effects of future developments on the viability of protected species. In this paper, we model population size and viability of selected indicator species for a selected area in Slovakia. Our results indicate that selected species are viable in the current landscape composition. However, the expected spread of settlement and the increase of road density in this area would likely lead to decline and loss of viability of species. Similarly, continuous land abandonment followed with spontaneous reforestation would likely trigger a decline of grassland species. In contrast, developing a biocorridor and restoration of existing green elements as modeled in our conservation scenario would strongly improve the viability of all species and avoid the impact of the expected developments. Our results underline the actions that prevent further loss of biodiversity in human-dominated landscapes and, thus, have particular importance for landscape planning and decision-making processes.
The main objective of the paper is to analyze and evaluate what are the manifestations and impacts of suburbanization in the hinterland of the city of Presov. The first manifestations of suburbanization started in 1996 and continue even nowadays. This process brings several consequences, economic, social, demographic, environmental, etc. When looking at migration flows, Presov has shown a long-term decline in population. The municipalities located in its hinterland show an increase in population. In this paper we will focus mainly on the impacts of suburbanization in the landscape - landscape fragmentation, arable land grabbing and leapfrog development. The emphasis of the paper is on the analysis of aerial and historical imagery and field research to provide mapping and photo-documentation of spatial aspects in the study area.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
