Cím:Trends and hotspots in landscape transformation based on anthropogenic impacts on soil in Hungary, 1990-2018 / Balogh Szabolcs, Novák Tibor József
Dátum:2020
ISSN:2064-5031 2064-5147
Megjegyzések:The transformation of the landscapes due to the anthropogenic activities is increasing worldwide. These changes are also manifested in the change of soil-forming processes. The land cover (LC) changes evaluated according to their influence on anthropogenic features of soils allows to distinguish between LC changes result-ing increased and decreased human impact (HI). In our study, we assess the changes of HI on landscapes and its spatial distribution across Hungary. The changes were evaluated by using LC data of four periods between 1990 and 2018 reclassified based on the related anthropogenic soil features. To identify the hotspots of the changes 1?1 grids were applied in which the direction (increasing, neutral or decreasing HI) and frequency (number of landscape patches with LC changes) of changes were evaluated. In our research, the hotspots were identified over the studied four periods. We point out that the spatial distribution of hotspots is very differ-ent. The hotspots of the increased human impact are 2,449 cells (643.0 km2) between 1990 and 2018, and the most of it localized in the Pest Plain (67), Csepel Plain (64) and Nagykálló-Nyírség (60). Most of the multiple hotspots are in the outskirts of Budapest to Kiskunlacháza, Bugyi, Délegyháza. As we examine the decreasing hotspot data we found 1,679 cells (1,524.9 km2) between 1990 and 2018. In largest number, they occur on the Kiskunság Sand Ridge (38), Majsa?Szabadka Sand Ridge (37) and Nagykállói-Nyírség (36). Multiple hotspots are located in settlements Izsák, Ásotthalom, Vatta and Nyírmihályi. Regions with numerous hotspots require special management to moderate its negative consequences on soils to consider both increased anthropisation, but also extensification of land use and their consequences.

Cím:Changes of the cultural landscape on Hajdúhát (Hungary)-from agricultural landscape to the monoculture / Márta László, Balogh Szabolcs, Novák Tibor József
Dátum:2019
Megjegyzések:The structural diversity, and complexity of land use and landscape components was studied in detail based on historic maps and recent remote sensed data in a study area on loess plateau of Hajdúhát, covered by chernozemic soils with 2500 ha extent dominated even traditionally by agricultural land use, first of all by crop production. At the end of the 19th century, at starting prosperity of individual farming in Hungary 79 individual farms could be found on the study area, in 1941 95, in 1962 154. In following period of the socialist restructuration of agriculture, the ongoing industrialization and expansion of intensive farming the earlier network of farms practically declined. In number of farms a strong decrease can be detected: in 1989 44, according the most recent remote satellite images only 38 farms still exists, and only 23 are in use. At the same time, the share of plough lands increased from 1751 ha (70%) at the beginning of the 19th century, to 2250 ha (90%) in recent times. Extent areas of former wetlands and meadows were occupied by plough lands. Until the 50s of the 19th century wetlands covered totally more than 500 ha (20%), actually they cover less than 10 ha (0.4%), extent of the mown meadows decreased to their third. The orchards, represented originally by an area of 0.8 ha, disappeared completely. The decline of the farm network is also detectably in changes of the road density. Int he first period the total length of roads was 93 km within the study area (3.72 2 km?km-), but it decreased to contemporary times to less than 50 km (2 km?km-2). Based on our results the spatial diversity, and complexity of the landscape characterized even earlier by plough lands showed ongoing reduction, and in recent condition could be characterized rather as agricultural monoculture instead of traditional cultural landscape.

Cím:Top-and subsoil mixing due cultivation as degradation risk on chernozemic arable lands / László Márta, Balogh Szabolcs, Novák Tibor József
Dátum:2019
Megjegyzések:Variability in depth of organic rich layer, vertical distribution of secondary carbonates, nutrient content and changes in bulk density can heavily influence topsoil fertility after long term cultivation and applying homogeneous plough depth. Increasing cultivation depth contributes also to mixing of organic- and nutrient poor subsoil to the fertile topsoil layer, which can be considered as a risk of soil degradation process. In case of erosion is associated with increasing plough depth and intensity, the natural variability and spatial pattern can disappear, and soil fertility decreases. In our study the soil vertical variability within Chernozem covered arable parcells of Hajdúság and Mezőföld loess plateaus were investigated in microscale. Arable parcells on homogeneous, flat loess coverd areas with low relief energy were sampled in detail (20-50 meter distances). Vertical distribution of SOC, N, P and secondary carbonates were measured. In Hajdúság, we found, that even on very flat areas, there are serious differences in vertical carbonate and humus status of the soils, and due to ongoing long time deep cultivation and mixing surficial soil layers, the topsoil quality can be degraded. In Mezőföld additional erosion contributes to decrease of topsoil fertility. The degradation influences even soil classification status, and should be minimized for sustainable use.

Cím:How geoecological components of a terroir can be altered by spatial changes of vineyards : a case study from Eger Wine District (Hungary) / Tibor József Novák, Balázs Hegyi, Szabolcs Balogh, Bence Czímer, Péter Rózsa
Dátum:2023
ISSN:0014-0015 2702-5985
Megjegyzések:Terroir is a concept referring interactions of natural (topography, lithology, climate, soil etc.) and human (eco nomic conditions, traditions, cultivation practices, etc.) factors; therefore, terroir is spatially delimited and subjected to en vironmental, socio-economic, and temporal changes. The geoecological background of wine districts are considered more stable among them, but, because of its natural diversity and the spatial changes of production sites, changes in abiotic terroir components might occur too. In this study the spatial changes of grape production sites in Eger Wine District (Hungary) across two and a half centuries (1784 to 2018), and their consequences on the composition of the geoecological factors (lithology, topography, soil characteristics) were analyzed. Modernization of cultivation, urbanization and increase of built up areas around the central settlement resulted in decreased concentration, i.e. increased spatial dispersion to more remote vineyards further from Eger. It also has consequences on the lithological and topographical composition of the production sites. Besides the slightly increasing extent of vineyards (from 5346 ha to 7413 ha) we found a distinct decrease of vineyards at higher elevations and a substantial increase at lower elevations. Distribution according to slope gradient changed also remarkably, with the share of vineyards on <5% slopes from 38% to 65%. These changes resulted in transformations of pedological characteristics according to the comparison of vineyard's extent with soil map data: vineyards shifted to slightly acidic, more fertile (i.e. deeper soil layer with higher organic carbon content) soils. The share of vineyards with different lithology and parent material also changed: loose, calcareous Tertiary sediments decreased almost to half, and the share of vineyards over acidic volcanics and their weathered regoliths almost doubled. Comparing these two dominant lithological types and soil profiles derived from them, different pedological characters and taxonomic status were found (Phaeozems and Vertisols). However, comparison of these two lithological types based on main topsoil characteristics (pH, SOC, carbon ates, depth of fertile soil layer, N, P, K content) according to 25 randomly chosen surficial soil samples at production sites, showed no significant differences.. In the case of this particular wine district, spatial changes of the production sites affected mostly the distribution by elevation, by slope gradient, but did not alter significantly the surface soil character of the terroir.

Cím:A novel approach to quantifying the degree of anthropogenic surface transformation : the concept of 'hemeromorphy' / Rózsa Péter, Incze József, Balogh Szabolcs, Novák Tibor József
Dátum:2020
ISSN:0014-0015
Megjegyzések:The degree of human geomorphological impact was estimated as a ratio of natural geomorphological processes and geomorphological processes triggered or facilitated by humankind. A typical Central European cultural landscape of diverse land use and relief was considered as a pilot area. Based on topography maps and landforms the natural material fluxes were calculated. By overlapping historical maps, modern maps and remotely sensed data, the duration and extent of different land use types were mapped, and were assigned to each landscape unit. Anthropogenic material fluxes were calculated for the land use types identified. Dividing the summarized anthropogenic material fluxes by natural ones, the anthropic geomorphological transformation ratio (rAG) was estimated. The value of rAG is independent of the efficiency and intensity of processes; it merely expresses the relation of effectiveness between human induced and natural processes. Since the calculated index is based on estimated values and there is, at least theoretically, no upper limit, the term ♭hemeromorphy' was introduced and the values were classified in corresponding ♭hemeromorphy' categories. For the smallest landscape units with the same degree of ♭hemeromorphy' the term ♭hemeromorphotop' was applied. This interpretation makes the comparison of landscape units possible according to their anthropogeomorphological transformation, independently of the intensity and quality of their geomorphological processes.

Cím:A historic geographic approach to the anthropic disturbance in the Bükk region / Sütő László, Balogh Szabolcs, Novák József Tibor, Homoki Erika, Rózsa Péter
Dátum:2021
ISSN:1789-4921 1789-7556
Megjegyzések:This paper introduce a historical geographical study on the process of land cover transformation in the Bükk Region, which can be regarded as a two-faced area concerning its anthropogenic disturbance. Based on historic mapping that began as early as the late 18th century, a database was produced, and the data was interpreted in the context of economic and social processes that took place in the area. Results could be presented in maps using the so-called Anthropogenic Disturbance Index (ADI). These maps demonstrate the peculiar land use pattern in the Bükk Region, namely co-habitation of the significantly transformed margins and the natural or quasi-natural central part. Between them, there are linear areas of intermediate disturbance. These areas, however, due to the foundation and activity of the Bükk National Park and modification of their economic value after the change of the political system, have not increased during the last several decades; rather a re-naturalization of the landscape is aimed.
