“…Violation of the scientifically based rotation of crops in crop rotations was facilitated by the parceling of agricultural land as a result of the reform of land relations (almost 85% of farmers farm on land plots up to 100 hectares in size), while the effective conduct of agricultural activities in market conditions in most cases can be ensured only by large-scale production. However, the concentration of large land allotments by agricultural holdings in one area not only creates threats of regional monopoly for the economy of the industry and the social development of rural areas, but also causes a further decrease in soil fertility due to the cultivation of highly profitable, export-oriented agricultural crops (grain and oil groups), which significantly deplete land resources [7,11,18,23].…”

Modern global trends in the development of agricultural land use convincingly prove the need to solve, along with the task of providing the population with food, the problems of environmental protection, preservation of biodiversity, reproduction of soil fertility [4,10,24]. That is why such systems of land use are formed, which prioritize not the maximum productivity of crops, but the preservation of functional connections between natural elements of the environment. Adaptive landscape systems of land use fully correspond to such directions, the main principles of which are environmental friendliness, adaptability, scientific capacity and biogenicity [2,6,11,30].Such principles make it possible to move from the concept of total intensification of land resources, the consequence of which is the degradation of the soil cover and the entire surrounding natural environment, to the concept of nature conservation adaptive landscape land use and ecologically balanced agroecosystems [5,7,26].An important step on the way to the formation of adaptive landscape land use systems is the rationalization of the structure of crops, taking into account the geomorphological, soil and economic conditions of specific regions [1,15]. Optimizing the structure of cultivated areas is the main, cheapest and ecological means of increasing the productivity of agroecosystems, ensuring more complete use of the bioclimatic potential of territories [5,12,28].However, radical transformations in the agrarian sphere of our country are mainly caused by market conditions without taking into account the requirements of environmental safety, have led to a significant increase in the share of highly profitable technical crops and a decrease in the area of crops of the fodder group; in particular, perennial grasses, which form the basis of soil-protective crop rotations [4,18]. Scientifically unsubstantiated expansion of the areas of intensive crops, as shown by the practice of the previous period and today, leads to the strengthening of degradation processes: erosion develops on sloping territories, dehumification and depletion of nutrients on plains; since economic entities on the land, in the vast majority, do not have the opportunity to compensate for the nutrients removed from the soil with the harvest of agricultural crops at the expense of organic and mineral fertilizers [1,12,14].The aggravation of these environmental problems today can lead to even greater economic losses and social troubles in the future, related to the food security of the country and the normative state of the natural environment [11,29]. Therefore, in order to ensure highly efficient, ecologically safe use of land resources, it is

“…The latter not only protect the soil surface from the destructive effects of torrential rains and strong winds, but also have a positive effect on the main parameters of soil fertility. Despite the fact that with extreme manifestations of erosion processes, the main anti-erosion load is carried by permanent measures that form the framework of an ecologically sustainable agro-landscape, the intensity of these processes largely depends on the properties of the soil cover, since the soil itself is the main component of any agricultural landscape and, at the same time, the object of direct influence of water erosion or deflation [5,7,11,23].…”

To ensure sustainable functioning of the agricultural sector of the state economy, balanced development of rural areas, increasing the ecological sustainability of agricultural landscapes is of key importance, especially in conditions of adverse climate changes [5,7,20,32].Climatic changes on a planetary scale can manifest differently at the level of individual regions, which is due to the indirect effect of climate on other interconnected factors of the ecosystem (in particular, soil-forming processes) [2,15,24].Taking this into account, in the Polissia zone of Ukraine, under the conditions of a change in the hydrothermal regime, the spread of such negative processes as desertification, impoverishment of natural systems, degradation of wetlands, accelerated mineralization of peatlands, frequent fires in coniferous forests, etc. is predicted. In addition, climate change can lead to "an increase in the number, intensity, coverage and duration of extreme weather and climate events", the frequent change of which increases the danger of deflation during droughts and water erosion during torrential rainfall [4,8,10,13,17].For the formation of the climate of Ukraine, which is generally considered favorable for agricultural production, the "microclimate manifested by the heterogeneity of horizontal and vertical gradients of climatological indicators" is important due to the complex interaction of the active surface in the systems of natural and anthropogenically modified landscapes, the functioning of which largely depends on level of economic development of the territory [5,22,24,30].A significant share of arable land in the structure of Polish agricultural landscapes increases their already significant ecological vulnerability to adverse external influences. Therefore, the solution to the problem of increasing the ecological sustainability of agrolandscapes in the conditions of Polissia should include, along with their anti-erosion management, optimization of the structure of land and cultivated areas (necessarily on the basis of relevant land management projects), and ensuring the ecological sustainability of the soil cover itself [1,6,11,18].The basis of anti-erosion management of agrolandscapes is permanent action measures, in which field protection forest strips play a special role [3,4]. It is the latter, in addition to providing reliable protection of the soil cover from deflation processes,

“…The consequences of such short-sighted policy are very tangible, especially in the industrial regions of our country, where due to man-made pollution, improper mining, unjustified land reclamation, global climate change, the earth is intensively degraded [4,22,26,28].…”
