wind energy, diffusion of innovation, social acceptance, regional development, Czech Republic

The paper deals with the initiation, localization and realization factors of wind energy development in the Czech Republic and analyses the relationship between the spatial distribution of this phenomenon and selected socio-economic, environmental and political-institutional indicators. The authors regard the development of wind energy as a process of spreading of a new technology in space and time or as an innovation diffusion which is in principle regionally uneven. The regional differences in the implementation of wind energy projects can be caused by a wide spectrum of interrelated factors, validity and significance of which in the conditions of the Czech Republic, is tested and interpreted. Emphasis is also put on the motivation factors and risk perception that induce the process of adoption or rejection of wind energy projects at the level of municipalities.

Land cover changes, driving forces, political changes, CORINE database, Czechia

The article deals with land cover change at a countrywide scale in the Czech Republic (i.e. Czechia) after the demise of the Communist regime in 1989. By using satellite images and calculating the change index, we were able to monitor the shifts from one class to another. Using a second method, we were able to analyse the differentiation within land cover structures within the individual spatial units (regions) of Czechia in 1990 and 2000. The article focuses on the consequences of political and economic processes as well as the determining influence of natural conditions on agriculture. With regard to the structure of land cover classes, the data revealed the growing heterogeneity of the regions of Czechia. Prior to 1989, the influence of the centrally planned economy on the uniformity of the land cover was considerable. Natural conditions did not play such an important role. By the end of the period of transformation, around the year 2000, the role played by natural conditions had become key in the changes in land cover.

protection of water sources, regional types, cluster analysis, Slovak Republic

The objective of the paper was to identify spatial relations between water sources, the rate of potential water resource hazard and also the typology of this relation, which can serve as a starting point for solving the problems with drinking water accessibility, supply and protection. Seventy-one Slovak districts were described by means of 7 parameters concerning water resource accessibility and hazard. For the use of cluster analysis, the principal component analysis (PCA) and setting of principal components on the file of 71 districts was performed. Orthogonal components were used as mutually independent variables of cluster analysis. Several variants of the hierarchical agglomerative method were tested. As a result, 14 regional types of water resource accessibility and hazard in the territory of the Slovak Republic were identified.

The main aim of this paper is to present the results of an analysis of the spatial localization of the Slovak diplomatic missions and embassies abroad and the foreign embassies accredited to the Slovak Republic with stress on the structure and geographical location of the various types of representative offices in the context of recent Slovak foreign policy.

accuracy, area weighting, dasymetric method, interpolation, land cover, road network, transformation

This paper introduces and evaluates some geographical data transformation methods which allow data allocation from spatially inconsistent zonal systems. The basic and simplest transformation method – areal weighting – is compared with complex techniques which use auxiliary information to improve the results of the interpolation process. Such auxiliary information is the length and type of road segments, the node counts in street networks and the class of urban fabric pursuing the CORINE land cover nomenclature. For comparison, different data types were used. Apart from the usually estimated variable – population counts – it was the area of agricultural land. These variables were available for the 1991 census districts and were estimated for the system of functional urban regions – FUR 91-B. The measures of global fit and spatial vizualisation of percent errors associated with all of the variables and methods were used to evaluate the results of estimation.
