The development of exogenous processes on the Earth's surface is a large-scale problem. Due to the development of exogenous processes there are changes in the composition and structure of the earth's crust and its surface. The destruction of streets, houses and public buildings, roads and railways leads to enormous losses. To predict the development of soil degradation, erosion processes on agricultural lands, which lose annual production areas, leads to the formation of a ravine-beam system and reduces the productive amount of land owned by citizens – is a solution. The use of GIS technologies, remote sensing of the Earth and modern programming can partially solve the problem, as it is a rapid identification of areas that have undergone the process of soil degradation and possible prediction of the development of negative phenomena. The use of geodetic software, GIS, information layers of the Public cadastral map can help in the fastest finding of territories, development of the forecast of the further destructive action, development of the corresponding protective methods and their introduction. The areas with manifestations of exogenous processes - soil degradation in agricultural enterprises, where every year the area of highly fertile chernozems is lost, which leads to large losses and landslides in the forest-steppe and steppe settlements of Kharkiv region have been subject of our study. We investigated destructive processes by geodetic measurements in the territories of their manifestations, observations were carried out for 8 years. The development of exogenous processes on the Earth's surface was revealed, which was manifested in landslides in the settlements of the forest-steppe zone and degradation of agricultural lands in the steppe and forest-steppe part of Kharkiv region. The cause of the destruction of the earth's surface were factors independent of human activity. We built 3-D models of development of exogenous processes manifested in soil erosion and growth of the ravine-beam system and determined the degree of erosion after surveying and processing the results of geodetic measurements in the software Digitals. For 8 years, we made changes to the software, surveying the area and building a monitoring line. Also in the settlements on the territory of the two zones, we observed the development of landslides on the streets of the village. Milova and s. Nova Vasylivka, where there is an intensive development of exogenous processes. The use of GIS technologies and remote sensing of the Earth to monitor the development of exogenous processes simplifies the solution.

The research of forest cover development on agricultural lands in the Perm Prikamye was carried the example of taiga and forest-steppe types of landscapes. The Babkinsko-Yugovskoy and Irensko-Kungursky landscapes were select for research. Received information about the geosystem condition in different years using remote sensing data. All landscape changes were record during the formed stable snow cover. As a result, was divide into two classes - forested and treeless areas. Established, the main natural factors of land differentiation by an areas and a pace of withdrawal from agricultural use are the small contours of agricultural land and differences in soil fertility. The growth pace of forest geosystems within the forest-steppe landscape was 2.5 times higher than of the taiga. The research of the dynamics of forest cover showed that in the Perm Prikamye in the forest-steppe landscape substitution of anthropogenic geosystems with natural-anthropogenic ("wild") accompanied by the development of forest biogeocenosis, not steppe.

Purpose: determination and analysis of the relevance of the geographic information systems (GIS) use in assessing the degradation degree of agricultural land as a result of erosion processes. Discussion: the article is devoted to the problem of studying modern methods for assessing the state of agricultural lands subject to negative processes. Water and wind erosion (deflation) are the most widespread and harmful types of soil degradation. So, water erosion (19.32 % of the territory of the surveyed lands) is the most widespread on the agricultural lands of the Russian Federation. The main tool for identifying soil degradation processes is the monitoring system, and the most effective and promising method for assessing the degree of land degradation is the Earth remote sensing (ERS) method. All of the above, together with reclamation techniques (land reclamation, field-protective afforestation, etc.) is a means of preserving and improving the quality of agricultural land resources, including those prone to erosion and deflation. The main advantages and examples of detecting soil degradation using remote sensing data are presented. The analysis of information on the spread of negative processes on the lands of the Russian Federation is carried out. Based on the analysis of the current state of land erosion, it becomes urgently necessary to carry out a set of measures to stabilize and restore the fertility of agricultural land. Conclusions: objective and reliable data on the state of soil erosion can be obtained only by combining ground (agrochemical surveys) and remote sensing methods of the Earth. Since the assessment of the degree and territorial distribution of soil degradation types can be carried out with high reliability using aerospace photography materials and ground-based research data, it is necessary to use remote sensing methods of the Earth and geographic information systems more widely, in addition to field surveys.

Reliable information on the real state of agricultural lands will be required to the development of appropriate measures for the rational use of agricultural lands. To obtain such information, it is necessary to keep permanent and systematic records and inventories of land resources. Large-scale special plans and maps will be required for accounting, inventory and classification of agricultural land. Currently in Uzbekistan such cartographic materials are being created on the scale 1: 10 000 and 1: 25 000 by administrative and territorial units, farms or individual land plots. The article considers the issues of creation of special maps of agricultural land in scale 1:10000 on the example of Sharof Rashidov district of Jizzakh region using remote sensing data with very high spatial resolution KOMPSAT-3.

Purpose: analysis of the features of visual decoding of eroded soils and erosion processes according to remote sensing data. Methods. Remote sensing, field, comparative geographical, historical, cartographic, GIS analysis. Results. The main attention in the article is paid to the features of visual decoding of linear forms of erosion. Comparative analysis of aerial photographs of 1943 and modern satellite imagery for the Kharkov region shown that in the second half of the 20th century the growth of gullies was almost stopped due to large-scale anti-erosion measures carried out at that time. Currently the main erosion losses occur in sheet erosion and small gully erosion. The article provides a list of decoding features that determine linear forms of erosion in the images. It is shown problems that can arise during automatic decoding. As an example of artifact formations requiring the participation of a human analyst in the decryption process, the so-called "Turkish Wall" is shown, the traces of which can be erroneously diagnosed as a manifestation of linear erosion Conclusions. Automatic decoding of water erosion processes and an inventory of erosion landforms requires the obligatory monitoring of a qualified analyst to eliminate object identification errors.

The paper deals with the problem of restoring rare communities of meadow steppes after plowing using the example of the Volga forest-steppe state nature reserve. The author has studied 9 uneven-age deposits in three forest-steppe protected areas: Kuncherovsky 5, Poperechensky 2 and Ostrovtsovsky 2. The study of deposits of different ages was carried out by the method of periodic large-scale geobotanical mapping using modern GIS-technologies. Maps of vegetation of different scale (1:5000, 1:10000, 1:25000) have been created. Deposits areas that adjoined to the virgin steppe were studied by a method of geobotanical profiling. At the same time, profiles (out of 1025 sample plots of 4 m in size) were laid at a distance of 10 m from each other. About 500 geobotanical descriptions were made at 9 different-age deposits at different times. Restoration of meadow steppes is impossible without the introduction of elements of anthropogenic intervention (moderate grazing and regulated haying) into the existing protection regime. Restoration of the steppes in an absolutely protected mode is possible only on the slopes of the southern exposure in forest-steppe landscapes of erosion-denudation plains (Kuncherovskaya forest-steppe).

Purpose.The analysis of the agroecological state of agricultural lands of Ukraine and the factors that cause soil degradation are given in the article. Conclusions. Large-scale use of straw for energy may be one of the key factors in reducing organic carbon in the soil. This will activate the processes of humus mineralization. Therefore, the use of straw for energy production does not meet the criteria of sustainable development and violates Ukrainian legislation on land use. The sustainable bioenergy development must be based on the biomass of high-productive bioenergy plants, which should be grown on low-yielding and degraded (marginal) land.

Soil is a core element of the biosphere, and the soil cover is exposed to major processes that take place within this system. Therefore, it is very important to understand the results of soil research from the perspective of current global and local environmental problems. With the advent of new methods of spatial analysis and techniques for obtaining remote sensing data, geoinformation technologies offer great opportunities for analyzing the natural and ecological state of the region. Therefore, geoinformation analysis of the state of natural and anthropogenic transformed soils is an essential tool for their studying, forecasting the development of the natural environment, and working out the ways of rational farming. As forest territories have a beneficial effect on the natural and climatic situation in general, and vice versa, environmental degradation on agricultural lands will result in worsening the situation on forest lands, it is necessary to consider forest and agricultural areas in close integration with GIS technologies. It should be done to improve the overall natural environmental conditions. The study used soil survey data conducted in 2017-2019. Field and office studies were conducted: samples were taken in the field to determine the agrochemical parameters of the soil, and the data obtained were analyzed using mathematical and statistical methods. Digital cartographic materials were created using geoinformation technologies. The basis for a comprehensive natural and environmental assessment of forest and agricultural areas using geoinformation systems was laid. The studies conducted to identify changes in natural and anthropogenic transformed soils have shown that the contours of soil varieties have changed. In many cases, there is a deterioration in soil properties. The number of fertile chernozem has decreased. In areas with low crop cultivation, there are signs of a decrease in the humus horizon and the development of erosion processes. As a result of the conducted research, a single digital soil and geographical database for forest and agricultural territories were created. The developed methodology and algorithm for creating a database and digital cartographic basis using geoinformation technologies in environmental studies can be recommended as a base for similar studies both in the Republic of Bashkortostan and in other regions.
