karst, doline, sinkhole, contagious model, logistic growth, environmental hazards, co-regionalization, cokriging

The Pennyroyal Plain of Kentucky and the Western Highland Rim of Tennessee provide a 25,000 karst-depression population for detailed study of karst landform evolution. Application of the contagion model and cogent logistic growth functions revealed fundamental principles governing the initiation and evolution of this complex, multifaceted karst geomorphic system. Accurate mapping of karst depressions is a complex process involving multiple data sets with high resolution and the development of a spatial database containing relevant geologic and geomorphic karst parameters. Implementation of spatial analysis and a geographic information system is necessary for spatial data presentation and developing karst hazards predictions. Rates of urban development in the karst landscape of the Western Highland Rim are among the highest in the southeastern United States. Therefore, understanding karst evolution, mapping karst landforms and developing hazards maps are important goals for efficient land use and urban planning. This paper develops a link between quantitative assessment of karst terrane and application of spatial co-regionalization theory.

borderland, micro-regions, qualification, social infrastructure, Czechia

The paper deals with border regions of the Czech Republic. 110 micro-regions were delimited in the borderland. The urbanized part of the borderland was excluded. The following indicators were used for the analysis: the population development between the 1991 and 2001 census, age index, share of people with post-secondary education, ethnic structure, share of population employed in the primary sector, share of flats built after 1945, share of uninhabited flats, equipment with technical infrastructure and social services, unemployment rate. The qualifications of people was identified as the main problem of the Czech rural borderland. It is closely connected with the social infrastructure. Micro-regions with centres under 2,500 inhabitants are considered the most problematic.

land use changes, agricultural land, arable land, transformation of agriculture, Czech agriculture, Czechia

The objective of this article is to assess changes in the spatial structure of agricultural land use (SALU) in Czechia in four time horizons – 1845, 1948, 1990 and 2000. A quantitative approach was adopted based on a combination of two indicators – share of agricultural land in the total area (SAGL) and share of arable land in the agricultural land (SARL). The Basic Territorial Units (BTU’s) of Czechia (8 903) were classified into four types of SALU – intensive (A), sharply intermediate (B), moderately intermediate (C) and extensive (D). Two different methods of classification based on median values of SAGL and SARL were used. It was found that each SALU type creates compact zones found in specific natural conditions. The A type with prevailing arable land occupies lowlands and lower highlands whereas the D type with prevailing forests can be found in mountains and higher highlands. The two intermediate types (B and C) create a transition, but the pattern of their occurrence is less obvious, compact and stable. During development, the occurrence of intermediate types decreased, and all SALU types tended to separate spatially to create more compact zones. It was a result of the changing energy and material “metabolism” of Czech economy, modernization of agriculture and growing regional specialization

Czech-Slovak frontier area, anatomy of area, settlement system, transport system

The common frontier of the Czech Republic and the Slovak Republic has experienced several stages of development in the transition period. The principal aim of the paper is to explain the settlement and transport structure of this area based on its morphological features and historical development. Transport interactions representing the mobile structural elements have also been included. These transport interactions are in fact flexible responses to the changes in the commuting and migration linkages. Mobile elements formed an important part of our research because in contrast to position elements, they rapidly and markedly changed after 1989 (or after 1993). The final result of the study is the schematic graphic model, which along with the final chapter synthesizes our knowledge about the anatomy of the frontier area between Czechia and Slovakia.

geographic organization, nature of geography, idiographic, nomothetic

The paper reacts to recent contributions of Czech and Slovak geographers to the debate about the role of idiographic and nomothetic conceptions in geographic inquiry and understanding. This kind of debate has been overcome in Western geography. The idiographic and nomothetic conceptions deal with the nature of description of geographical facts and do not offer an adequate framework for their explanation. The paper documents shortcomings of the debate looking at three examples: Hartshorne/Schaefer’s discussion about exceptionalism in geography, the theory of geographical organization of Hampl and the concept of the hybrid idiographic-nomothetic nature of geography proposed by Matlovič. It concludes that retaining the prominent position of the issues of nomothetic and idiographic types of inquiry would rather obstruct than stimulate further disciplinary development in our geography.
