Socio-political changes in the countries of Eastern and Central Europe in the era of socialism had significant effects on agricultural landscape. Collectivisation (1950 - 1970) lost almost all of traditional agricultural landscapes. On the other hand, the phenomenon of agricultural abandonment started to be significant after 1989. In the model area (part of The Polana Biosphere Reserve) these two processes that formed the agricultural landscape structure were analysed. The analyses were carried out using orthophotos that represented the landscape structure in 1949, 1986 and 2006. It was found that almost complete extinction of the traditional agricultural landscape represented by a mosaic of narrow fields and permanent grasslands occurred during the period. At the same time, increasing trend of abandonment processes was observed. In 2006, non-forestwoody vegetation covered 48% of agricultural land.Natural reforestation as the final stage of agricultural abandonment extended to 46% on the former agricultural land in 2006. Abandonment processes were the most significant already in the period of socialist agriculture. To describe the changes, landscape metrics such as Number of patches (NP), Mean patch size (MPS), Patch size standard deviation (PSSD) and Mean shape index (MSI) were used.

Agricultural land in many post-socialist countries passed through a similar scenario of eminent changes in the past decades. One of the important milestones was the process of collectivisation (in 1950−1970), transformation to market-oriented economy (after 1989) and the following integration into the European Union. These changes were often attended by the process of agricultural abandonment. This paper presents an approach to the evaluation of agricultural abandonment by analysis of land use change in chosen terrain attributes (slope levels and altitude levels) context. It studies the area of a northern part of the Poľana UNESCO (United Nations Educational, Scientific and Cultural Organization) Biosphere reserve that represents mountain agricultural landscape. All of the analyses were realised in GIS (geographic information systems), based on the orthophotos that represented the land use structure in 1949, 1986 and 2006. Dramatic decrease in real usage of agricultural areas attended by the process of secondary succession was observed especially in steep slopes and higher altitude levels. To quantify the changes, landscape metrics such as class area (CA), number of patches (NP) and mean patch size (MPS) were used. Changes in landscape classes had an influence on landscape diversity. It was expressed by decrease in Shannon‘s diversity index (SDI) and Shannon‘s evenness index (SEI).

Protected mountain areas are attractive tourist destinations, and the number of visitors to these areas is increasing. The extension of cable car operations into the summer season is a challenge for some protected areas. Our study focuses on visitor profiles and is based on the characteristics of socio-demographic and spatial behavior of cable car users of the Chopok area (Slovakia). The methods used involve recording visitors’ itineraries through the use of GPS loggers and conducting post-trip interviews with the study participants. In order to better understand visitors’ spatial behavior, the relationship between socio-demographic characteristics and trip itinerary parameters was analyzed. Additionally, three distinct visitor profiles based on cluster analysis were found in the investigated sample. The results can be used to enrich our knowledge concerning the spatial behavior of tourists in mountain environments, and more directly, for the management of cable car destinations located within protected areas.

UAV-based photogrammetry has many applications today. Measuring of snow depth using Structure-from-Motion (SfM) techniques is one of them. Determining the depth of snow is very important for a wide range of scientific research activities. In the alpine environment, this information is crucial, especially in the sphere of risk management (snow avalanches). The main aim of this study is to test the applicability of fixed-wing UAV with RTK technology in real alpine conditions to determine snow depth. The territory in West Tatras as a part of Tatra Mountains (Western Carpathians) in the northern part of Slovakia was analyzed. The study area covers more than 1.2 km2 with an elevation of almost 900 m and it is characterized by frequent occurrence of snow avalanches. It was found that the use of different filtering modes (at the level point cloud generation) had no distinct (statistically significant) effect on the result. On the other hand, the significant influence of vegetation characteristics was confirmed. Determination of snow depth based on seasonal digital surface model subtraction can be affected by the process of vegetation compression. The results also point on the importance of RTK methods when mapping areas where it is not possible to place ground control points.

Water retention is an important hydrological ecosystem service of active floodplain soils. The aim of the study was to evaluate the soil chemical, physical, and hydrological properties in Fluvisols in three different ecosystems that have an impact on water retention hydrological ecosystem services (WRHESs). We selected 16 localities along the Štiavnica River in Central Slovakia, 8 located in riparian zones (RZ), 5 in arable lands (AL), and 3 in grasslands (GL). Soil samples were collected from two layers (0–10 and 20–30 cm). In the laboratory, the soil physical (soil texture) and soil chemical properties (pH, soil organic carbon content, humic and fulvic acid ratio) were determined. Using undisturbed soil samples, the soil physical characteristics (particle density, bulk density, porosity, and actual soil moisture–SMa) were measured. With the help of pedotransfer functions, hydrological soil properties (field water capacity–FWC, wilting point–WP, available water capacity–AWC) were estimated. The recorded properties differed between the localities, ecosystems, and two layers. The SMa values showed a higher soil water retention potential of extensively used ecosystems, such as GL and RZ. However, the hydrological properties estimated by pedotransfer functions (FWC, WP, AWC) showed a higher soil water retention potential in AL localities. This indicated that for calculations, selected pedotransfer functions (particle size fractions, organic matter, and bulk density) and other soil or ecosystem properties (e.g., vegetation cover, meteorological conditions) have an impact on WRHESs. One such soil factor can be the quality of organic matter. On the basis of the results of the ANOVA, significant differences emerged between the different ecosystems for selected basic chemical, physical, and hydrological properties. The effect of the soil layer on the soil properties was revealed only in the case of SOC. The results indicated the effect of different ecosystems on soil WRHES and the importance of extensively managed ecosystems, such as RZ and GL. From this point of view, the reduction in the RZ and GL areas during a period of the last 70 years is negative. The findings should be taken into account in future sustainable floodplain management and landscape architecture.

The contribution deals with abandoning of agriculture land of the chosen mountain village area (cadastres Povrazník and Strelníky ÚvodSlovenské poľnohospodárstvo a následne poľnohospodárska krajina prešla za obdobie posledných desaťročí veľmi výraznými zmenami, ktoré priniesli svoje pozitívne, ako aj negatívne dopady. Tieto zmeny je obzvlášť vhodné analyzovať v podhorských a horských oblastiach, ktoré z hľadiska charakteru krajiny a úrodnosti pôd nemožno označovať za typicky poľnohospodárske. Poľnohospodárstvo a poľnohospodárska krajina tu má svoje charakteristické črty, ktoré dokumentujú historický vývoj týchto oblastí a dotvárajú ich prírodnú hodnotu.Etapa slovenského poľnohospodárstva od roku 1989 až po vstup do Európskej únie sa zvykne nazývať ako transformačné obdobie (Zaušková, Krajčovič, 2011). Po roku 1989 sa v dôsledku spoločensko-politických zmien ocitlo hospodárstvo Československa v recesii (Ižáková, 1994). Poľnohospodárstvo začalo čeliť veľmi pomalej reštrukturalizácii s problematickými privatizáciami štátnych majetkov a prudkým nárastom agrárnej nezamestnanosti. Transformácia bola legislatívne upravená zákonom č. 42/1992 Zb. o úprave majetkových vzťahov a vyrovnaní majetkových nárokov v družstvách. Situáciu zhoršovala neujasnenosť vlastníckych vzťahov, reštitúcie, vysoká rozdrobenosť pôdy, rast cien vstupov, nedostatok vlastného kapitálu, dlhy, ako aj nedostatočné úverové zdroje (Pitoňák, 1994). Mnohé družstvá boli transformované na iné právne formy, viaceré zanikli. Začali sa prejavovať výrazné dopady na krajinu, najmä v podobe procesov
