sustainability concept, geography, regions, Krkonoše Mts.

The article is aimed at the possibilities of application of the sustainability concept on the regional level, with special regard to possibilities of spatial differentiation based on the analysis of sustainability, which can be projected into sustainable management of regions. After introducing some basic remarks on the sustainabi-lity concept the article discusses potential of geographical science for the research of sustainability and highlights contribution of geography to renewal of the paradigm of sustainability that seems to stagnate mostly at the global level. Theoretical suggestions are then briefly applied to the region of the Giant Mts. (Krkonoše), Czech Republic, which, as a Biosphere Reserve, are predestined to be such a research issue. The main contributions of geography to the sustainability concepts are seen in the ability of synthetic approach to the research issues and ability of spatial differentiation, which enables us to examine lower hierarchical levels.

ecological network dynamics, ecological stability, landscape protection, renewable energies

An ecological network is a set of ecosystems linked into a spatially coherent system, which might change over time but needs to keep its conservation and stabilizing potential. The aim of the paper is to show how an ecological network in the study area of Záhorie changed over fifty years, to analyse former and remaining ecological connections in the landscape and to highlight current barriers to network operation. The following aim is to outline the potential negative environmental effects of renewable energy sources and the necessity to locate renewable energy installations under the constraints of nature conservation. Land cover databases representing the state of the landscape in 4 time horizons (1954, 1979, 1992 and 2003) were used for the analysis of landscape changes. Ecologically important segments identified in the land cover maps represent the most ecologically valuable areas and form the basis of the ecological stability system. The study focused on changes in stabilizing elements and changes in the ecological stability of the landscape system as they are important for the planning of any human activity. The present trends in energy management point to the fact that renewable energies will gain a more important position in the energy structure of the individual European Union (EU) countries. Assuming further expansion of renewable energy sources (RES) in the landscape, it is also expected that the anthropogenic impact on the landscape will increase. It may result in changes to the original geosystems. Territories primarily suitable for the development of RES represent a significant developmental potential and their environmental limits must be considered in relation to the existing anthropogenic layer, human interests and the protection of nature.

ethnic boundary, Slovaks, Hungarians, Galanta district

The ethnic boundary from the geographical point of view was presented as a spatial phenomenon. It is presented as a social boundary with projection in space; and the development of the ethnic boundary, here conceived being boundary between two ethnic groups – Slovaks and Hungarians. The development of the ethnic boundary in the Galanta district in the years 1880-1930 is described and presented in maps. The paper also contains a map of the ethnic boundary in 2001, portraying the outcomes of ethnic processes emerging in the fifties and sixties.

factors of migration, migration flows, structure of migrants, regional population forecast, variants, hypothesis

The paper deals with analysis and forecast of migration on the local level. The subject of our study is Petržalka, a city ward of Bratislava and the biggest urban structure in the Slovak Republic. We analyse recent migration situation, especially the main migration indicators, migration flows and structure of migrants. Factors of recent rapid change are analysed. Three main variants of future migration have been produced on the basis of this detailed analysis.

geomorphological division, units, boundaries, nomenclature, Slovakia

The paper deals with theoretical problems of the geomorphological (orographic) division of Slovakia and transposition of boundaries of geomorphological units from map with the scale 1:500 000 (Mazúr and Lukniš 1978) onto the scale 1:50 000. Criteria applicable to creation of boundaries to geomorphological units with occurrence of carbonate karst are evaluated. The change of hierarchy of geomorphological units (wholes, subwholes and parts), as well as delimitation of new units on the level of subwholes and parts for Slovakia is desirable for more detailed map scales.
