transformation of agriculture, land use, productive agricultural regions, Slovakia, Districts: Dunajská Streda, Levice, Prievidza, Stará Ľubovňa

The transformational changes after 1989 were reflected in many aspects of the life of our society; they also had a major impact on agricultural production and affected land use. These changes were caused primarily by major social changes including transformation of the economy and agriculture. Slovakia was also affected by globalization. The aim of this article was to characterize the changes in land use and their spatial distribution in relation to the transformation of society after 1989 using the examples of the Dunajská Streda, Levice, Prievidza and Stará Ľubovňa districts. The districts represent the productive agricultural regions of Slovakia. The prevailing processes in land use in the districts as a result of dominant factors will be documented.

crime, gender, age, fear, urban space, geographical research

Crime and fear of crime and its relevance for geographical research is assessed in this article. The focus is on the role of space in criminal processes and reactions. Crime and fear are considered spatial phenomena. Disposition of people to become victims was emphasized and fear of crime factors were identified including the socio-cultural ones, those linked to the biological body traits and social factors, as all of them are linked to space which can be one of the fear of crime triggers. Eventually a selection of the most important theories and methods in the geographical field was presented.

solar energy, photovoltaic, renewable energy, Slovakia

Solar energy plays an increasingly important role in the diversified mix of energy sources in Slovakia. By the end of June 2011, almost six hundred photovoltaic power plants had been completed with a total installed capacity of 467 MWp. In this paper, the solar resource potential in Slovakia and economic factors leading to a development of photovoltaic power plant projects at concrete sites are analysed. The conclusion is that the major factors influencing the localization of photovoltaic power plants are the development costs, feed-in tariffs and interest rates valid in the time of starting the project. The installed capacity of the photovoltaic power plants has shown a very weak correlation with the actual solar resource potential. The proposed change in the state support scheme preferring feed-in tariffs set via auctions should press investors to a thorough evaluation of the solar resource potential for all considered power plant sites.

debris flows, dendrogeomorphology, debris fan, the Moravskoslezské Beskydy Mts., the Bučací potok Brook

It is important to know the history of occurrence of debris flows, especially with respect to the potential prediction of their origins in future under the changed climate conditions. The temporal occurrence of debris flows in some localities in the Moravskoslezské Beskydy Mts is known. Nevertheless, it is necessary to replenish these data. Debris flows were dated using the dendrogeomorphic methods in the valley of the Bučací potok Brook on the northern slope of the Smrk Mt. Increment cores and cross sections from 35 predominantly broad-leaf trees growing near the debris flow track were used for dating. Eleven debris flow events from the last 70 years were identified. The reconstructed frequency of debris flows makes it obvious that activity has increased since the mid-1980s. Origins of all debris flows are connected with the occurrence of extreme short-term precipitation totals (often more than 200 mm/day). This study should contribute to the knowledge of debris flow chronology in the Moravskoslezské Beskydy Mts.

geomorphology, denudation chronology, planation surface, river valley, cave morphology, speleogenesis, paleomagnetisms, U-series dating, pollen analysis, Belianske Tatry Mts., Slovakia

Geological and geomorphological research in the Belianska Cave conducted during the last decade has gradually revealed its complicated multi-phased genesis especially during the pre-Quaternary period. The origins and evolutionary phases of the cave were formulated on the basis of detailed studies of the geological structures, cave morphology, composition and dating of sediments. The primary phreatic morphology with voluminous cupolas was sculptured by the deep phreatic waters ascending along a steep fault between the central and the edge of the eastern parts of the Belianske Tatry Mts. Fine-grained cave sediments as residues from dissolved carbonate rocks can be dated to ca 4.18–6.15 Ma. Some morphogenetic features of the cave give evidence of the hydrographical connection with the evolution of landforms in the eastern part of the Belianske Tatry Mts. and the adjacent area. On the basis of relicts of planation surfaces, the cave morphology and dating of cave sediments the multiple-phased development of the Biela River Valley in relation to the development of the subhorizontal epiphreatic passages in the upper (Pontian?) and the lower parts (Upper Pliocene, Lower Pleistocene) of the Belianska Cave were reconstructed.
