“…Amongst the different natural hazards in Hungary, mass movements (primarily landslides) are concentrating only in small areas, while soil erosion by wind can amount to as much as 80-110 million m 3 annually, with 10% of the total area of the country being susceptible to wind erosion [45,50,51]. Soil erosion by water affects about 24.7% of the total area of Hungary [18,21].…”

As soil erosion is still a global threat to soil resources, the estimation of soil loss, particularly at a spatiotemporal setting, is still an existing challenge. The primary aim of our study is the assessment of changes in soil erosion potential in Hungary from 1990 to 2018, induced by the changes in land use and land cover based on CORINE Land Cover data. The modeling scheme included the application and cross-valuation of two internationally applied methods, the Universal Soil Loss Equation (USLE) and the Pan-European Soil Erosion Risk Assessment (PESERA) models. Results indicate that the changes in land cover resulted in a general reduction in predicted erosion rates, by up to 0.28 t/ha/year on average. Analysis has also revealed that the combined application of the two models has reduced the occurrence of extreme predictions, thus, increasing the robustness of the method. Random Forest regression analysis has revealed that the differences between the two models are mainly driven by their sensitivity to slope and land cover, followed by soil parameters. The resulting spatial predictions can be readily applied for qualitative spatial analysis. However, the question of extreme predictions still indicates that quantitative use of the output results should only be carried out with sufficient care.

Monitoring air pollution and environmental health are crucial to ensure viable cities. We assessed the usefulness of the Air Pollution Tolerance Index (APTI) as a composite index of environmental health. Fine and coarse dust amount and elemental concentrations of Celtis occidentalis and Tilia × europaea leaves were measured in June and September at three sampling sites (urban, industrial, and rural) in Debrecen city (Hungary) to assess the usefulness of APTI. The correlation between APTI values and dust amount and elemental concentrations was also studied. Fine dust, total chlorophyll, and elemental concentrations were the most sensitive indicators of pollution. Based on the high chlorophyll and low elemental concentration of tree leaves, the rural site was the least disturbed by anthropogenic activities, as expected. We demonstrated that fine and coarse dust amount and elemental concentrations of urban tree leaves are especially useful for urban air quality monitoring. Correlations between APTI and other measured parameters were also found. Both C. occidentalis and T. europaea were sensitive to air pollution based on their APTI values. Thus, the APTI of tree leaves is an especially useful proxy measure of air pollution, as well as environmental health.

The concept of landscape degradation interprets the process in landscape ecological sense, i.e. the degradation of one landscape forming factor leads to the degradation of the whole landscape. The consequence is a persistent decline in land productivity and in the provision of other ecosystem services. Global environmental change is driven mainly by human influence in the Anthropocene with an exponentially growing significance in time. Global environmental processes are very much interrelated. Because of population growth more food, fibre, clean water, energy etc. will be needed and there are two ways to achieve this, either to gain new areas for cultivation by changing present land use or to intensify cultivation in the areas with the best conditions for cultivation. Deforestation and forest degradation are dealt with in detail in the paper. The introduction of soil degradation processes follows the system given in the EEA Environmental Assessment Report (2003). The effect of landscape degradation on ecosystem services is well explained by the fact that approximately 20 per cent of the Earth’s vegetated surface shows persistent declining trends in productivity, mainly as a result of land/water use and management practices (UNCCD 2017). Landscape degradation processes of Hungary are discussed in the paper, including sheet, gully and wind erosion, soil sealing, salinization, physical degradation, landslides, desertification. An estimation of the aesthetical value of the landscape is provided as well concluding that the surface of the country represents a relatively high aesthetical value. The main conclusion is that Hungarian landscapes are well maintained and they belong to the most precious European landscapes. It should be added that all degradation processes represent important environmental problems to be combatted on the basis of a well-established policy making.
