At the present time the great part of soils is exposed to various negative processes. One of the basic processes that lead to the degradation of soils in Ukraine is the erosion. According to the recent data, water and wind erosion covers 13.9 million hectares; it is about 33 % of the total arable land in the country. On this basis, the greater relevance belongs to the scientific studies displaying the features of negative phenomena of our soil, and, most importantly, the ways of solving of these urgent problems on the soil cover of Ukraine. The monograph «Soil erosion in Ukraine: the evolution of theory and practice» of such famous scientists in the field of Soil Erosion Science as Voloshchuk M. D., Petrenko N. I. and Yatsenko S. V. is one of such fundamental works. In the present monograph, considerable attention is paid to the periodization of the formation and development of the doctrine of soil erosion in Ukraine. The authors identify six basic stages of formation of the national Soil Erosion Science. The paper discusses the characteristic features of isolation of Soil Erosion Science as an independent scientific direction and a self-discipline, which are based on the works of such renowned scientists as P. S. Tregubov, M. N. Zaslavsky and G. I. Shvebs. A significant place in the monograph is devoted to the characteristics of the scientific centers of Ukraine, in which the Soil Erosion Science has been developed. These centers are distinguished by leading scientists, under the leadership of whom, the erosion processes have been studied. The authors of the monograph provides four main scientific centers of the country in the field of Soil Erosion Science development: National Scientific Centre «Institute of Agriculture of the National Academy of Agricultural Sciences» (central region), National Scientific Center «Institute for Soil Science and Agrochemistry Research named after O. N. Sokolovsky», Scientific-Technical Center «Fertility» (Kharkiv region), Odessa I. I. Mechnikov National University (south region), Lviv National Agrarian University, Institute of Ecology of the Carpathians of National Academy of Sciences of Ukraine, Ivan Franko National University of Lviv and others (west region). In addition to considering the features of the listed centers, in the work there is a presentation of a brief description of the project, research institutes, agricultural and agroforestry research stations that are active in a scientific work in relation to soil erosion processes. In the work, there are also the historical aspects and mechanisms for the further development of wind erosion researches. Considerable attention the authors of the monograph pay to the analysis of the current state, challenges and prospects of solving the problem on protecting the soil from erosion. The main problem of the country's soil, which is the cause of widespread erosion, is a very high agricultural development of the territory, more than half of which falls onto an arable land. At the end of the monograph, there are a large number of photos, provided by Professor M. D. Voloshchuk, which recorded various aspects of soil erosion manifestations, as well as the ways of its overcoming in the conditions of forest-steppe and steppe zones in Ukraine and on the territory of Moldova. The reviewed monograph is certainly a very relevant and timely generalizing scientific research that will be useful in the theoretical and practical use of students, academic staff of the natural and agricultural higher education institutions, research organizations.

Abstract Soil erosion by wind is the primary land degradation process which affects natural environments and agricultural lands. In agricultural lands, soil erosion by wind mainly results from removing of the finest and most biologically active part of the soil richest in organic matter and nutrients. Repeated exposure to wind erosion can have permanent effects on agricultural soil degradation. Knowing spatial and temporal changes in soil conditions and soil erodibility is essential to understand wind erosion processes. There are many methodologies to predict the susceptibility of landscape to erosion. The more complex is the scheme combining multiple factors, the more accurate the estimate is. There are very few studies on mapping the changes in soil grain size and erodible fraction due to wind erosion. Existing studies only deal with eroded soil units (where particles are removed – deflation) and not the eroded units (areas) to which the eroded particles are wound – accumulated. Prevailing wind direction should also be taken into account when mapping changes in erodible fractions of wind-eroded soils and the nature of the soil (whether soil particles accumulate or deflate). In this study the “historical“ grain size distribution of the soil in three cadastral areas using data from complex soil survey (1968) and year 2018/2019 was analysed. Erodible fraction change was also calculated and compared for both time periods.

Soil erosion, especially water erosion, is one of the most widespread types of soil degradation, not only worldwide, but also within the Czech Republic, where it endangers more than a half of the agricultural land. In addition to farming, the landscape structure has a significant impact on soil erosion in the conditions under study, where, especially in the post-war period, the collectivisation of large-scale arable land was accompanied by the abolition of the associated landscape elements. The agricultural production area of South Moravia is one of the most endangered areas in the Czech Republic, therefore, it was selected for our research, whose main objective was to verify the sensitivity of the selected physical, chemical and biochemical characteristics to identify the changes in the soil properties in the erosion processes at the identified erosion areas. The testing was carried out within a period of 5 years in 60 locations with Chernozems with cultivated corn. To assess the quality of the soil properties, indicators of soil quality from the physical, chemical and biological – biochemical groups were selected. The results of the analyses and the subsequent statistical evaluation showed that the chemical characteristics, especially those related to the quantity and quality of the organic matter, were the most sensitive to the changes in the soil properties. From the biochemical indicators, some enzymes, particularly dehydrogenase and acid phosphatase, reacted sensitively. The physical characteristics were not significantly affected by the erosion processes.

<p>The aim of the study was an integrated application of methods for the identification and complex assessment of ecosystem responses to abiotic stress factors as extreme runoff, muddy floods and soil erosion processes.  The protection of land with flysch geological structures with regard to and the problems caused by extreme runoff are a very important task in water management. The unsuitable management of land and irresponsible land use causes the formation of flash floods on watersheds and results in accelerated soil erosion. The decreasing soil quality and excessive sedimentation of eroded material in the water structures, which are components of flood protection structures, are a consequence of accelerated soil erosion. Research on and the design of measures were realized on five small watersheds in the cadastral area of the village of Vrbovce, which is situated in western Slovakia, on the edge of the flysch zone of the White Carpathians. Flash floods regularly recur in the village of Vrbovce, and extreme runoff causes the formation of rill erosion on the arable land. The soil erosion was modelled by the Universal Soil Loss Equation and the topographic factor was calculated by the Usle2D program. The results of the calculations show that 96.19 % of the agricultural land is endangered by accelerated soil erosion, with the values of the average annual soil loss greater than the limit for the tolerance of soil erosion. We calculated the direct runoff for five selected watersheds of the Teplica river tributaries with the CN-SCS method. The flooded areas in the village were modelled by the 2D hydrodynamic model MIKE21. A set of measures, i.e., polders, an infiltration trench and agrotechnical measures on the arable land, was designed outside the built-up areas of the village of Vrbovce for the reduction of the extreme runoff and accelerated soil erosion. Measures for the Teplica river revitalisation in the village were proposed. From the estimation of effectiveness of the measures proposed follows that we were able to reduce the amount of the soil erosion to values permissible for the norm by the proposed measures.</p><p>Key words: soil erosion, flash floods, flood protection, erosion control and river revitalisation practices</p>

Since soil erosion is one of the processes that have a significant negative impact on land resources, as well as the economy, it is very important to determine the main types of erosion, calculate the process of soil erosion, rationalize and organize its prevention. Soil erosion is most often observed on fine-grained soils, in areas with high humidity and strong winds, with severe erosion, soil fertility is lost, which accordingly leads to a deterioration in the quality of agricultural products. Today it is effective to use the RUSLE formula to determine the main factors affecting soil erosion processes. The article examines the Ulysai river basin, located in the Burlinsky district of the West Kazakhstan region. In the course of the study, the coefficient of soil erosion for pastures was 0.007...0.09 t/ha per year. On arable land, the value of the coefficient A of soil erosion was 0,2...0,83 t/ha per year.


Purpose. To reveal changes of climatic conditions in the region of Zaporizhia, which directly affect the development of soil erosion processes of the region Methods. System analysis. Results. It has been established that the process of climate warming is accompanied with an increase in average annual temperatures during the period of 2005-2017 by 1.7 ° С on the average. The general positive trend also indicates a significant increase in the sum of active temperatures above + 15 ° С. The average long-term increase in the sum of positive temperatures has been around 40 ° C per year according to the data of the meteorological observing station of Melitopol; at the same time, within the period of 2008-2012 there was a double growth of this indicator - up to 80 ° C per year. The change of wind circulation with the prevalence of western component leads to an overall increase in precipitation up to 500.0 mm on the average (the meteorological station of Melitopol). At the same time, the amount of rainfall is being redistributed towards the winter season, which causes an increase in dryness during the vegetation season. Both the increase in the average annual temperature and the redistribution of precipitation between seasons is accompanied with an increase in the frequency of droughts, especially from the second half of the twentieth century until the present time. In addition, an increase in the amount of rainfall in the winter period and the exposure of agricultural fields is followed with accelerated water erosion of the soil, with the deflation processes being activated in early spring. Conclusions. It has been revealed that changes in the climatic conditions, which are occurring on the territory of the region of Zaporizhia, are accompanied with an average long-term increase in the sum of positive temperatures, an increase in the average annual temperature of the air and a decrease in the wind-circulatory processes.The change in climatic conditions has caused the activation of water and wind erosion. Wind erosion is common on the surface adjacent to the Azov Sea coast, as well as on the surface of the Pryazovia Highlands and windward slopes. Water erosion processes are confined to short and steep slopes, which essentially depend on the amount of precipitation and soil properties.

The article presents a scientific literature review in the field of modern methods of monitoring wind erosion of soils such as: visual indicators of erosion, erosion bridge, close-range photogrammetry, cesium-137 and remote sensing cover. The brief description of each method, advantages and disadvantages, conditions and limitations of their applicability are given. When choosing the method, it is necessary to take into account the monitoring conditions, the area of the territory under consideration and the scale of research, time frames, financial and labor resources. It has been established that the most relevant, economically justified and promising, especially on large territories, are the remote sensing methods, which allow monitoring on different scales, and not only estimating the erosion activity, but also predicting it, thus providing the parties concerned with the necessary information for making right, prompt and timely economic decisions, aimed both at combating wind erosion and elimination of its consequences, and for organizing preventive measures as well. To improve the effectiveness of these methods it is also necessary to create databases, expand and accumulate soil information that can help verify, refine, process and calibrate the satellite data obtained. In order to understand aeolian processes and dust particle transport mechanisms one should create integrated methods that include remote sensing data, meteorological data, on the basis of which the improved models and maps would be developed, and erosion processes would be predicted. The scientific literature is mostly devoted to the interpretation of wind erosion in arid and semi-arid zones. The possibility of satellite monitoring of soil erosion in arable fields remains poorly studied. There are also practically no research results available on the transport of chemicals with micro-particles due to wind erosion. Both in Russia and abroad the attempts are made in soil erosion modelling, but the quality of the models is very limited by the lack of field data required for their calibration and verification. Eroded soils in the country are still identified using ground-based methods. However, field studies can only be conducted in a very limited area, in a few key points, and as a matter of fact it is quite complicated to conduct field studies on actively used agricultural lands.

The experience of the development and use of the system of dry farming in the Stavropol Territory is considered, the causes and prerequisites for the emergence of an adaptive-landscape farming system are identified. It is shown that the farming systems of the Stavropol Territory are in constant development, they function in conditions of the joint manifestation of water and wind erosion. As a result of degradation, a third of the arable land of the region is in the zone of erosion processes. The expediency of the development of a universal soil protection system of agriculture, aimed at protecting the soil from water and wind erosion, is substantiated.

After the reform in the mountainous zone of the Transcarpathian region, there are currently 15 territorial communities, which have united 75 village, settlement and city councils, which include 130 settlements. In this area 80.2% are hayfields and pastures. Another 0.5% of the area is occupied by perennial plantations, and 5.21 thousand hectares or 19.3% of the total area is allocated for arable land. The most susceptible to erosion processes are soils under row crops, in particular under potatoes and other roots. Withdrawal of eroded lands from agricultural lands is the most ecologically justified and economically feasible way of their use. Keywords: mountain zone of the Carpathians, structure of agricultural lands, soil, erosion processes.

Land degradation, especially soil erosion, is a societal issue that affects vineyards worldwide, but there are no current investigations that inform specifically about soil erosion rates in Chinese vineyards. In this review, we analyze this problem and the need to avoid irreversible damage to soil and their use from a regional point of view. Information about soil erosion in vineyards has often failed to reach farmers, and we can affirm that to this time, soil erosion in Chinese vineyards has been more of a scientific hypothesis than an agronomic or environmental concern. Two hypotheses can be presented to justify this review: (i) there are no official and scientific investigations on vineyard soil erosion in China as the main topic, and it may be understood that stakeholders do not care about this or (ii) there is a significant lack of information and motivation among farmers, policymakers and wineries concerning the consequences of soil erosion. Therefore, this review proposes a plan to study vineyard soil erosion processes for the first time in China and develop a structured scientific proposal considering different techniques and strategies. To achieve these goals, we present a plan considering previous research on other viticultural regions. We hypothesize that the results of a project from a regional geographic point of view would provide the necessary scientific support to facilitate deriving guidelines for sustainable vineyard development in China. We concluded that after completing this review, we cannot affirm why vine plantations have not received the same attention as other crops or land uses.
