    The abandonment of farmland has become a widespread phenomenon in post-socialist countries that have seen revolutionary changes in their economic systems. The phenomenon is notable in vineyard areas, where abandonment leads to the loss of the unique character of vineyard landscapes. This paper assesses the extent of vineyard abandonment in Slovakia and analyses the driving forces behind it. We used statistical and Corine Land Cover data to map the change in vineyard areas in Slovakia and analyse the pressure of underlying driving forces.

    Landscape structure not only reflects the natural settings of the landscape but also its history and the impact of human activity. Information about the characteristics of the landscape elements in terms of their structural functionality plays a central role in assessing their ecological quality. Statutory designation of sites plays a key role in conserving and maintaining valuable parts of the landscape. In this study, we investigated whether protection status influences functionality in case studies from the Czech Republic, representing three different landscape types.

    Calamagrostis villosa has recently expanded in Nardus stricta-dominated sub-alpine grassland of the Giant Mountains (Krkonoše/Karkonosze, the Czech Republic). To investigate whether this expansion has been promoted by high nitrogen deposition or by the cessation of agricultural management, grassland plots dominated by C. villosa were manipulated with four treatments: control (Con), fertilised (Fer), cut (Cut) and cut-fertilised (Cut-Fer).

    Alaria alata is a potential zoonotic parasite, which is widely distributed in Eurasia. To assess the risk of human infection, it is important to know the spatial distribution pattern of the parasite and factors influencing this pattern. To investigate these relationships, 1612 red fox (Vulpes vulpes) carcasses were randomly collected from the whole Hungarian territory, and the intestines were examined by sedimentation and counting technique. The spatial distribution of the parasite was highly clumped.

    This paper presents a complex analysis of both the contemporary and the historic development of the geomorphic regime of the transformed reach of the Morávka River in the Czech Carpathians. The assessment concentrates on the conditions and causes of the channel development in the last c. 200years compared with the state of European channels, especially those of the Carpathian zone. The Morávka R. pattern has undergone a rapid change in the last 50years, particularly in connection with the active channel narrowing and massive incision.

    This article explores the development of the social metabolism of Czech agriculture over the past 80 years and aims to describe the complex agricultural system from a biophysical perspective. As a Central European country, the Czech Republic's political system has experienced a number of turning points and changes in its history. Using the social metabolism concept and the material and energy flow method of analysis this article looks at the system from a biophysical perspective and explores the interactions between the economic system and nature.

    The status of urban forests and other green open spaces has always been ambiguous within the context of rural-urban peripheries. On one hand, most European countries have introduced protected green zones around cities to contain their sprawl and to provide urban dwellers recreational space and sanitation services since the early days of city planning policies. On the other hand, the ecosystems of green open areas remain under high pressure due to high demand for suburban land, causing issues ranging from illegal dumping to ecosystem fragmentation and forest loss.

    The migration of young people from rural areas is common in all agricultural regions of Russia, and Altai Krai, located in southwestern Siberia, is no exception. Out-migration, aversion to working in agriculture and the aging of farmers and farm managers are serious problems that raise questions about who will work in agriculture in the future. This paper aims to investigate factors that affect the decisions of agricultural students from Altai Krai to out-migrate or to return to their rural parental municipalities after finishing their university studies.

    REVEALS-based quantitative reconstruction of Holocene vegetation cover (expressed in plant functional types, PFTs) is used in the LANDCLIM project to assess the effect of human-induced land-cover change on past climate in NW Europe. Using the Czech Quaternary Pollen Database, this case study evaluates the extent to which selection of data and input parameters for the REVEALS model applications would affect reconstruction outcomes.

    The paper aims to position the concept of adaptive efficiency in planning theory, by providing insights on the conditions that explain why land use planning in some institutional contexts is able to adapt and improve more efficiently than in others. This is done by focusing on a specific planning goal: the control of residential sprawl. The paper presents a theoretical framework based on two models, one on the coordinating mechanisms regarding the use of land and one to explain institutional changes.
