Megjegyzések:: The increasing number of visitors and conflicts resulting from shared use in valorising sensitive wetlands make effective visitor and site management measures essential. In the course of this research, the landscape pattern, the current spatial distribution of tourist activities and the possible arrangement of expedient further development were examined. The study area, Lake Tisza, is an artificial lowland reservoir established in the 1970s with an area of 127 km2 in Hungary. Among its original functions, in addition to flood control, nature conservation and recreation have become the main profiles. The diverse hydro-ecological features and mosaic landscape structure allow for nature conservation and utilisation in tourism. This differentiated use is in line with the worldwide trend of favouring locations with multiple leisure activities in close proximity to each other. Based on the CORINE Land Cover (CLC) 2018 database, 12 different land use categories were identified in the study area. The largest proportion is represented by water bodies (53.29%), while inland marshes and broad-leaved forests cover 22.25% and 16.64%, respectively. The heterogeneity of the area is considerably enhanced by the high patch sizes of the categories pastures, broad-leaved forests and inland marshes. According to the Shannon diversity index, the most complex landscape diversity can be found in the Tiszavalk (1.5) and Poroszló (1.4) basins, considered to be the most suitable for ecotourism, while the lower values of the Sarud (1.1) and Abadszalók (1.1) basins provide suitable conditions for water sport activities and recreational tourism. Continuous adaptation to social needs and the joint protection of natural values is crucial for the sustainable development of Lake Tisza.

Cím:Biological geotextiles as a tool for soil moisture conservation / Kertész Ádám, Szalai Zoltán, Jakab Gergely, Tóth Adrienn, Szabó Szilárd, Madarász Balázs, Jankauskas Benediktas, Guerra Antonio, Bezerra Fernando, Panomtaranichagul Mattiga, Chau, Dao, Yi Zheng

Megjegyzések:Geotextiles have an important influence on soil moisture conditions. It is well known that the application of geotextiles increases soil moisture content of the soil, but there is a lack of information on how the different mats keep the soil moisture. The objective of this paper is to present the effect of biological geotextiles on soil moisture dynamics of the topsoil and to compare the effectiveness of various geotextiles in conserving soil moisture as well as comparing their role in soil moisture dynamics in the different climatic zones. Soil moisture measurements were carried out in the framework of the BORASSUS project at six study sites in Brazil, China, Hungary, Lithuania, Thailand, Vietnam. Soil moisture was measured by gravimetric method. All together six different kinds of biological geotextiles (Borassus, Buriti, Bamboo, Jute, Maize and Rice) and one synthetic geotextile were used. To study soil moisture dynamics of the geotextiles applied in Hungary 1000 cm3 soil monoliths were covered by Jute, Buriti and Borassus mats. The effects of natural rainfall events on soils and geotextiles were examined in detail. According to the results of this paper there is not much difference concerning the effect of biological geotextiles made from various materials on soil moisture conservation. There are, however, remarkable differences in conserving soil moisture according to the geographical location of the study sites. The favorable effect of geotextiles on soil moisture conservation could be statistically justified if annual precipitation amount is over 700 mm and the annual temperature range is below 28 °C.

Cím:The effects of uninsulated sewage tanks on groundwater. A case study in an eastern Hungarian settlement / Mester Tamás, Szabó György, Bessenyei Éva, Karancsi Gergő, Barkóczi Norbert, Balla Dániel
Dátum:2017

Megjegyzések:In our study we attempt to demonstrate the effects of uninsulated sewage tanks, which are the most importantsources of contamination in settlements without sewage systems, on groundwater quality. We comparedthe results of measurements carried out before and one and a half years after the construction of the sewage system.We established 3 m deep monitoring wells within a 25 m radius of a sewage tank, which were then sampled,and the level of groundwater was recorded. The 3D model constructed on the basis of the saturated zoneshows that the effluent wastewater formed a groundwater level dome with a height of more than 1 m. After thesewage tank was taken out of use the difference between the highest and lowest groundwater levels decreased toa few centimetres. In our study we investigated the spatial distribution of NH4+ (ammonium). Using the 3D modelwe were able to precisely determine the volume of water bodies with different levels of contamination. In anapproximately 25 m3 water body, in the immediate environment of a sewage tank in use we detected NH4+ ata concentration which was characteristic of undiluted wastewater (>90 mg?dm?3). After the sewage tank was takenout of use, the concentration in its immediate environment decreased by more than 50%, although almost everywherein the modelled area concentrations were measured above the limit value. Based on the above, we canconclude that the cleaning process has started, but the complete decontamination of the groundwater will takeseveral years.

Cím:Performance evaluation of machine learning algorithms to assess soil erosion in Mediterranean farmland : A case study in Syria / Safwan Mohammed, Ali Jouhra, Glory O. Enaruvbe, Bashar Bashir, Mona Barakat, Firas Alsilibe, Luc Cimusa Kulimushi, Abdullah Alsalman, Szilárd Szabó

Megjegyzések:The development of new techniques, such as machine learning (ML), can provide better insight into the processes and drivers of soil erosion and runoff. However, the performance of these techniques to assess soil erosion in agricultural landscapes is poorly understood. The aim of this study was to evaluate the performance of four machine learning algorithms, Generalized Linear Model (GLM), Random Forest Regression (RF), Elastic Net Regression (EN) and Multiple Adaptive Regression Splines (MARS), in predicting soil erosion and runoff in Syria. Soil erosion and runoff were measured on three experimental plots (2.25 m ??1.50 m ??0.50 m, 0.10 m depth in the soil), combined with 3 different slopes and land use types: RS (8%, olive), SS (12%, citrus), KS (20%, pomegranate). Both erosion and runoff were determined after rainfall events of >10?mm between October 2019 and April 2020. Based on 24 effective rainfall events, the average soil erosion was 0.18?0.14 kg/m2 per event in KS, 0.14?0.11 kg/m2 per event in SS, and 0.12?0.10 kg/m2 per event in RS. Regression analysis indicated strong relationship between the rainfalls and the runoff, the highest connection was recorded in the KS plot (r2=0.85; p<0.05, n=24). The analysis of covariance indicated that only the runoff had a significant impact on soil erosion (p=0.02) with a medium effect (?2p=0.26). However, the impacts of rainfall events and slope categories on soil erosion were limited (?2p<0.01) and not significant (p>0.05). ML techniques were usually efficient in the prediction, the RF and MARS models were the most accurate: RF had the strongest correlation with the measured values (r=0.85) with a low estimation error (0.06 kg/m2), but MARS's standard deviation (SD) was closer to the recorded values' SD. GLM and and EN were the weakest predictor models. Modelled values of the slightest slope (8%) had the worst accuracies, and the predictions of the 12% slope were the best in all models. This study provides important insights into the usefulness of machine learning techniques and algorithms in predicting the rate of soil erosion and runoff in agricultural dominated landscapes. We highlighted that the RF and MARS algorithms were better predictors of soil erosion and runoff in the coastal region of Syria.

Cím:Changes in the Patterns of Population Distribution and Built-up Areas of the Rural-Urban Fringe in Post-Socialist Context : A Central European Case Study / Pénzes, János; Hegedűs, László Dávid; Makhanov, Kanat; Túri, Zoltán
Dátum:2023
ISSN:2073-445X
Megjegyzések:The rapid and significant expansion of urban areas is observed worldwide; however, considerable differences are detected within the characteristics of the process. The rural-urban fringe is changing most dynamically from the aspect of land use and this tends to be relevant in the case of post-socialist cities in Central Europe even with a stagnating or decreasing population. Debrecen (Hungary) and its hinterland adequately represent the migration trends of Hungarian cities and the great administrative area provided wide intra-urban suburbanization processes. The current study put the emphasis on the analysis of the spatial pattern of built-up areas and the distribution of residents. In order to discover the processes of the post-socialist transition period, detailed point layers were created to illustrate every built-up parcel in the rural-urban fringe of Debrecen (for the years 1980, 2000, and 2020). The most important characteristics were discovered with the help of GIS methods-Kernel-density, grid pattern analysis of the object density, and analysis of land cover/land use changes using Corine Land Cover Change (CLCC) databases. The dynamic and extended expansion of built-up areas was seen until 2000, in which the outskirts (including hobby gardens) densified spectacularly. The urban sprawl has been less intensive since the millennium and the increase in built-up areas has become more concentrated. As a consequence of the transition period, extended territories-primarily the least dense parts of the rural-urban fringe-are faced with the disappearance of buildings due to agricultural cultivation reasons.

Cím:Effects of Land Use and Wildfires on the Habitat Selection of Great Bustard (OTIS TARDA L.) : Implications for Species Conservation / Zsolt Végvári, Orsolya Valkó, Balázs Deák, Péter Török, Sándor Konyhás, Béla Tóthmérész
Dátum:2016
ISSN:1085-3278
Megjegyzések:Increasing agricultural activities have been shown to affect soil and vegetation changes leading to serious biodiversity declines throughout the world. These effects are amplified in dry grassland areas, where resulting changes in habitat structure affect threatened animals on long temporal scales. Great bustards (Otis tarda) inhabit open landscapes where fire and grazing have been a part of the natural disturbance regime since historical times. Even fire and grazing are hypothesized to be important factors in the lifecycle of the species, studies are still missing on disturbance-related lekking distribution patterns of great bustards. We analyzed the importance of fires and grazing on the spatial distribution of lekking bustards controlling for habitat types, habitat diversity, distance from roads and social effects. Our standardized dataset spanned 31 years, being one of the largest datasets on bustard lekking. During the 31 years we observed 10 118 individuals at 639 observation points in Hortobágy National Park, East-Hungary. One of the most important predictors for total number of birds and number of males was the area burnt in previous years. We found that increased habitat diversity had a positive effect on female numbers. Models fit on second- and third-year burn data detected no substantial role of burning on lekking distribution. Our results suggest that introduction of a patch-burning management system in lekking areas could increase the availability of optimal lek sites for bustards. As an effective management tool, we suggest applying patch-burning annually in a spatially mosaic structure inside the area occupied by each sub-population unit.

Cím:The Eurasian crane (Grus grus) as an ecosystem engineer in grasslands: Conservation values, ecosystem services, and disservices related to a large iconic bird species / Orsolya Valkó, Sándor Borza, Laura Godó, Zsolt Végvári, Balázs Deák
Dátum:2022
ISSN:1085-3278
Megjegyzések:Large bird species, such as cranes are involved in human-wildlife conflicts as they often forage in croplands. The Eurasian crane (Grus grus) is a large bird species, protected across Europe, which, thanks to conservation programmes and its ability to utilise croplands for foraging, shows a strongly increasing population trend. This exaggerates the existing conflicts between crop farmers and cranes and is spilling over to natural habitats, where foraging by large flocks can lead to land degradation. No studies have evaluated the effects of foraging cranes on grasslands, despite the fact that these habitats provide important feeding grounds for cranes across their whole range. To fill this knowledge gap, we evaluated the ecosystem engineering effect of foraging Eurasian cranes on the vegetation of dry grasslands in Hungary. We used indicators of vegetation naturalness, forage quality, and floral resource provision to evaluate the ecosystem state from multiple aspects. We sampled 100 quadrats in disturbed patches and 100 in undisturbed grasslands in two seasons and 2 years (800 observations). Cranes created distinct vegetation patches with different species composition from undisturbed areas. We identified important trade-offs between the positive and negative effects of the foraging activity of cranes on different structural and functional components of the ecosystems. The crane-disturbed early-successional patches increased plant diversity and floral resources but decreased the area of undisturbed grasslands. Although crane-disturbed patches could provide forage for livestock early in the season, the forage quality became poor later in the year. We highlight the importance of monitoring the landscape-level extent of the disturbed areas.
