The article deals with the issues of the current state and the degree of anthropogenic transformation of landscapes. On the example of the landscapes of the Andropovsky district of the Stavropol Territory, the types of land use are analyzed, and the anthropogenic load is estimated. The obtained data allow us to identify the places most exposed to anthropogenic impact and in need of preventive measures to protect the landscapes. The results of the study can be used to optimize the structure of land use in the Andropovsky district and for further research on the problems of anthropogenic impact on landscapes.

With the increasing number of megacities, the constant expansion of their borders, and the often chaotic, unreasonable land-use planning, even those sites with potential recreational use suffer from enormous anthropogenic pressure. Defining the limits of ecosystem stability is one of the most important scientific research, which allows setting permissible anthropogenic impact in the land cadastre zoning of megacities. This investigation presents the integral assessment of net anthropogenic load on the environment and boundaries of the natural soil geochemical background change.

Land Use Structure

Purpose. To assess of the land use structure of Ternopil city united territorial community and justify the priority areas for its optimization. Methods. Descriptive, comparative-geographical, geoinformation, statistical, mathematical, geoecological analysis and optimization modeling. During the study, special methods were used to determine the anthropogenic load, coefficients of ecological stability and anthropogenic transformation of the Ternopil city united territorial community. Results. Analyzing of the land use structure of Ternopil city united territorial community, it was found that the share of natural lands within it is only 32.5%. The main geoecological problems of the land use of Ternopil city united territorial community are the imbalance of land structure, the lack of master plans of rural settlements and territorial boundaries, the lack of inventory and regulatory monetary valuation of land. The coefficient of anthropogenic transformation of the territory of Ternopil city united territorial community is 6.7, which corresponds to the category of highly transformed landscapes. The coefficient of ecological stability of the Ternopil city united territorial community is 0.28, the territory is ecological unstable with a score of anthropogenic load of 3.22. The geoecological assessment of the land use structure of Ternopil city united territorial community, testified the need to optimize the structure of land and to introduce effective scientifically sound measures. Conclusions. To correct and improve the situation, bringing the territory of the Ternopil city united territorial community to ecological stability, it is necessary to implement optimization measures. In the study we have developed an optimization model of land use in the Ternopil city united territorial community, which provides for the reduction of arable land by 18%, increase in forest cover by 12% and bringing the share of natural lands to the optimal 50%. The implementation of such an approach requires a change in the purpose of individual land plots and the organization of their landscape-adapted use.

The Impact

Land use changes influence the water balance and often increase surface runoff. The resulting impacts on river flow, water level, and flood should be identified beforehand in the phase of spatial planning. In two consecutive papers, we develop a model-based decision support system for quantifying the hydrological and stream hydraulic impacts of land use changes. Part 1 presents the semi-automatic set-up of physically based hydrological and hydraulic models on the basis of geodata analysis for the current state. Appropriate hydrological model parameters for ungauged catchments are derived by a transfer from a calibrated model. In the regarded lowland river basins, parameters of surface and groundwater inflow turned out to be particularly important. While the calibration delivers very good to good model results for flow (Evol =2.4%, R = 0.84, NSE = 0.84), the model performance is good to satisfactory (Evol = −9.6%, R = 0.88, NSE = 0.59) in a different river system parametrized with the transfer procedure. After transferring the concept to a larger area with various small rivers, the current state is analyzed by running simulations based on statistical rainfall scenarios. Results include watercourse section-specific capacities and excess volumes in case of flooding. The developed approach can relatively quickly generate physically reliable and spatially high-resolution results. Part 2 builds on the data generated in part 1 and presents the subsequent approach to assess hydrologic/hydrodynamic impacts of potential land use changes.

Abstract Human activity is a factor strongly influencing the current state of vegetation. The abandonment of traditional land use enables uncontrolled secondary succession. Libanotis pyrenaica, a host plant for Orobanche bartlingii, is a great example of species that spread as a result of this process, especially in the area of the Silesian-Cracow Upland. The aim of this study is to show that the expansion of L. pyrenaica caused by changes in land use promotes spreading of O. bartlingii - a species rare in Poland and Europe. During the field research conducted in the last decade, further localities of O. bartlingii were found. The gathered data were summarized to supplement the known distribution of the species and to present floristic and ecological characteristics of the phytocenoses with the participation of L. pyrenaica and O. bartlingii.

An effective implementation of the sustainable use of agricultural land program is impossible without reliable results of the current state of the problem. In this sense, the correct selection of indicators and methods for determining the level of stability is important. The authors proposes the definition of the agricultural land use sustainability integral indicator based on three methodological approaches: the construction of the indicators system, each of them reflects some aspects of the land use sustainability at the macro level (according to the specific issues); the construction of the integral indicator for comparing the countries’ land use sustainability. According to the given methods it has been proved that agricultural land use in the countries of the post-socialist camp has a positive dynamics, but the sustainability indicators for all indicators have not achieved yet. This study was supported in part by the Erasmus SUPPA program – Jean Monnet Associations Application No 611556-EPP-1-2019-1-UA-EPPJMO-SUPPA.

Urban Watercourse

The anthropogenic impact on urban rivers is very significant. Industrial enterprises, municipal, and agricultural organizations discharge wastewater directly into the rivers. In the samples of the studied water, certain properties were found. The water in the river is cloudy, brown in color, and in some places has a sharp smell. Extraneous impurities and foam were detected in water. Moreover, various chemicals were found, which are not characteristic to natural waters. The analyzed water is highly polluted as shown by the following chemical indicators, which reported results higher than the Maximum Allowable Concentration: Fe concentration is 24 times higher than standard, Cu is 5 times higher, Mn is 6 times higher, Al is 366 times higher, Hg is 3 times higher, Zn is 4 times higher, NO2 is 2.5 times higher, hydrocarbon pollution is 2.8 times higher, NH4 is 1.9 times higher. Therefore, it is necessary to immediately develop effective methods for monitoring the state of the watercourse, both economic and energetic. To save the sustainable development of the natural system.

The purpose of the publication is to present the results of the study of anthropogenic changes in the landscapes of the Forest-Steppe zone of Ukraine, implemented by assessing the indicators of landscapes anthropogenic transformation, their diversity and fragmentation. The basic research methods are methods of geospatial GIS analysis and decoding of remote sensing data of the Earth, geoinformation mapping. According to the indicators of anthropogenic transformation of landscapes at the level of physical-geographical regions and districts of the Forest-Steppe zone, the features of changes for the period 1992-2018 are determined. The results of assessment of anthropogenic changes in forest-steppe landscapes of Ukraine show that in 1992 as well as in 2018 the vast majority of the landscapes of the territory are strongly and excessively transformed by anthropogenic activity. Such patterns persist, despite the fact that during the analyzed period in part of the investigated area there is a certain decrease in anthropogenic pressure on landscapes. The regular relations between the indicators of anthropic landscape diversity and fragmentation of landscapes are determined, which corroborates to their certain conditionality by the degree and nature of anthropogenic transformation of the territory. The novelty of the study are the proposed methods of spatial and temporal changes in landscapes estimating and identifying such changes in landscapes at the level of physical and geographical regions for the period 1992-2018 and revealing trends in the structure of land use, especially agricultural lands, forests, built-up territories as the leading types of land use in the Forest-Steppe zone of Ukraine.
