The Creation

Purpose. To characterize the methodological approaches that we develop in the formation of a system of information support for the creation and maintenance of the functioning of modern sustainable agricultural landscapes and to show the results of their implementation on the example of the territory of some agricultural enterprises of the Kharkiv region. Methods. Cartographic, geoinformation analysis, calculation, statistical and mathematical. Results. Some results of the work of the collective on the issues of information support for the creation and maintenance of the functioning of modern sustainable agricultural landscapes. Namely, verification of erosion models, studies of the functionality of shelter belts, the formation of an agroeconet (an extensive network of natural and quasi-natural landscapes) on agricultural land massifs, which ensures the maintenance of stable functioning of meso and macrolevel agrolandscapes, as well as the experience of using magnetic prospecting methods to verify the results of mathematical modeling of erosion processes. Conclusions. A number of methodological approaches to information support of the formation of sustainable agricultural landscapes in the natural and socio-economic conditions of Ukraine have been developed. They relate to the functioning of anti-erosion measures of permanent action, the processes of modern transformation of agro-landscapes, the ecological impact of erosion processes on the environment. The connection between the length of forest belts per unit of arable land and soil erosion is shown. A methodical approach has been developed to estimate the amount of soil washed away from arable land and to calculate the measures necessary to eliminate its harmful effects on the environment.

The aim of the work was the landscape analysis of agricultural geographical landscapes in the Altai Territory and elaboration of measures aimed at the rational use of agricultural lands. Environmental and landscape (landscape) approach became the main method of scientific research used in the analysis of modern agricultural landscapes. The cartographic method, using GIS-technologies, made it possible to digitize the obtained materials. Synthesized maps of agro-ecological, natural and other zoning of territories are based on topographic, soil, geobotanical and other thematic maps made during land surveying during the field survey. Retrospective analysis, induction and deduction methods,analysis and synthesis, as well as the abstract-logic method were also used in the work. Our main result was the analysis of land use territory for agricultural enterprise in municipal district of Altai Krai. Exploration of lands indicates a pronounced plant-growing specialization of JSC “Pobeda” with a developed animal breeding direction. Limiting factors affecting the rational use of land are natural and climatic conditions, terrain,unsystematic anthropogenic activity and, as a result, the development of erosion processes. The degree of eroded and deflated arable land is more than 50%, hay and pasture lands are also very unstable. Landscapes have been typified, based on which eleven types of land have been identified and their geomorphological description has been carried out. The first five types of land can be used for agricultural production with limitations compensated by crop technology and erosion control measures, the sixth and seventh types require grassing and, in some cases,conservation, the eighth and ninth types can be partially used for pasture and area valorization; the remaining two are not suitable for agricultural use but should be potentially used for planting and forest management. As a result of the presented transformation of agricultural lands, the structure of cultivated areas has changed. The area of arable land decreased by 877 ha, and of pastures by 365 ha,while the area under hayfields, fallow lands, and forest lands increased by 295, 191, and 875 ha respectively. Low-productive lands were withdrawn from agriculture. We suggested that the sustainability of agricultural land use was mainly caused by the reduction of anthropogenic load and increase in ecological equilibrium of the territory.

From acceptance of the 1948 Plan of Field-Protective Afforestation to the present (2019), this article considers the new agroforestry paradigms protracted formation. Scientific achievements from the 1940s, introduced into practice, served as the basis for decisions on natures global transformation. Pilot facilities from the beginning of the 20th century (the Bogdinsky agroforestry stronghold, the Stone-steppe oasis) still serve as reference objects for agroforest reclamation of territories, with a scientific approach that allows them to function productively today. The plans main idea is to combat drought and desertification of steppe lands, erosion processes, and to prevent sand and dust storms. Creation of 5709 thousand hectares of protective forests, afforestation of 1106 thousand hectares of ravines, fixing and afforestation of sand on an area of 322 thousand hectares, and implementation of many planned activities during a short period locate this plan among other ambitious international projects. The authors draw attention to the time of creation and the volume of plantings of paramount importance, that is, state protective forest belts and protective forest plantations. Understanding the importance of agroforestry for modern agricultural landscapes led to formation of sustainable and durable agroforestry systems in subarid landscapes based on a combination of agricultural and landscape-ecological ideologies. Allegedly, considering terrain ecotopes, three-dimensional evaluation of the agrolandscape and a non-linear approach make it possible to create multifunctional, highly productive agroforestry systems in critical agriculture zones.

On the example of the territory of the Altai Krai, the article traces the consequences of destruction of the natural landscapes structure, the creation of artificial elements of their ecological framework of agricultural landscapes, which currently needs restoration and optimization. The thesis is substantiated that the ecological frame of the Altai Krai territory should be as close as possible to the structure of its natural landscapes, which will ensure the productivity of farmland. The most important elements of the ecological framework of forest-steppe and especially steppe landscapes are forest belts, for the creation of which it is necessary to use elements of a water-erosion network, tree species that form a zonal type of vegetation. Creating a system of protective forest plantations in combination with ponds and terrace embankments can increase crop yields up to 25-50 centners per hectare. Landscape planning can serve as a tool for creating an ecological framework for a territory.

Based on generalization of literary sources, normative legal, stock materials and experimental data, the complex situation of soil degradation is highlighted. Different types and intensity of the manifestation of soil degradation, their distribution and characteristics are described. The threatening situation of manifestation of degradation processes in some regions of Ukraine is shown, among which soil erosion occupies the leading place. More than 4.5 million hectares are occupied by medium and strongly ground soils, including 68 thousand hectares completely lost their humus horizon. Particularly large areas of eroded soils are distributed on arable land in the Vinnytsia, Luhansk, Donetsk, Odesa, Chernivtsi and Ternopil regions, where the average annual ground wash is 24.5–27.8 t/ha with a tolerance of 2.5–3.7 t/ha. As a result of erosion processes from the total area of agricultural land, about 500 million tons of fertile soil layer is washed out on average annually, which contains about 24 million tons of humus, 0.96 million tons of nitrogen, 0.68 million tons of phosphorus and 9.4 million tons of potassium equivalent to 320–333 million tons of organic fertilizers, and ecological and economic losses due to erosion exceed 9 billion UAH. Flat soil was associated with linear erosion. The main indicators characterizing the degree of damage to land by linear erosion are the density of ravines, the distance and area between them, the slope, the properties of soils and rocks, the morphometric parameters of the ravines and their catchment areas. According to various estimates, the area of land affected by linear erosion in the country increases by 5–10 thousand ha annually. The effect of the ravines on the complete destruction of the land, deformation of the soil cover is highlighted. Information on various types of soil pollution by poison chemicals, industrial waste is given. According to the prediction of scientists in such a situation, 120–150 years on the planet can destroy the fertile soil layer. Key words: erosion, dehumidification, pollution, waterlogging, acidity, degraded land.

Purpose: to establish the basic principles of the organization of reclamed agricultural landscapes and to substantiate the use of the agricultural landscape approach in the organization of the territory. Materials and Methods. When preparing this article, the materials of Russian scientists dealing with the issues of soil fertility conservation and ecological sustainability of reclaimed agricultural landscapes were considered. The methods used were analysis, generalization, synthesis and other methods of working with literary sources on this issue. Results. In performing the work, the main principles and indicators were determined, such as productivity, sustainability, the rule of transforming measures for the natural environment, optimization of the agricultural landscape, authenticity, principles of the formation of reclaimed agricultural landscapes, the complexity of the reclamation impact, the required diversity, the uniqueness of the reclamation impact. The basic requirements for the preservation of soil fertility of reclaimed irrigated agricultural landscape have been established. It was found that to maintain ecological balance within the irrigated agricultural landscape, it is necessary to adhere to the indicators of the reclamation load of the natural environment. The limits of agricultural lands saturation in reclaimed agricultural landscapes for various agro-climatic zones have been substantiated and recommended. Conclusions. It has been determined that the coefficient of reclamation loading of irrigated lands, showing the maximum share of irrigated lands that can be irrigated in a particular climatic zone, varies from 0.3 in the forest-steppe zone to 0.60–0.85 in the semi-desert and desert zone. This suggests that with an increase in moisture supply, this indicator decreases, the recommended amount of agricultural land in various agroclimatic zones varies from 30 to 87 %, while the area of arable land should not exceed 20–25 % in a very dry zone, and with an increase in moisture supply, it can increase up to 80 % in the semi-arid zone. The amount of irrigated land in the reclaimed agricultural landscape should not exceed 18–20 %. Irrigated meadows and pastures should account for 1–2 to 5–6 % of the area.

The article is devoted to the formation of the institutional environment of ecologically safe agricultural land use through the model of harmonization of ecological and economic interests of the subjects of agricultural land use. The structure of agricultural land use is based on criteria, the content of which represents both economic and environmental interests of society. For example, the landowner (land user) is interested in converting his land into the most economically attractive - arable land, which reflects his private economic interests, and on the other - society is interested in maintaining the optimal state of agricultural landscapes, which in turn provides the optimal ratio of destabilizing, stabilizing and stabilizing reflecting the public environmental interests [7]. Usually such differentiation of interests of subjects of agrarian land use causes situations of impossibility to agree them voluntarily. Therefore, there is an urgent problem in effective regulatory policy in the field of land use, in particular through the formation of the institutional environment of environmentally friendly agricultural land use through the model of harmonization of environmental and economic interests of agricultural land users. In the article, it is clarified that the institutional model of harmonization of ecological and economic interests of subjects of agrarian land use provides for the introduction of tools to eliminate the conflict of ecological and economic interests, which includes a number of tools, levers and techniques, in particular: -adaptation paradigm; formation of ecological consciousness of land users, ecological morality and ethics; development of the organizational and economic mechanism of formation of ecologically safe agrarian land tenures and land uses optimum through a combination of market and state levers of influence; regulatory and legal support of ecological safety of agricultural land use; optimization of the organizational structure of land use management.

Agricultural land use systems have been optimized for producing provisioning ecosystem services (ES) in the past few decades, often at the expense of regulating and cultural services. Research has focused mainly on the supply side of ES and related trade-offs, but the demand side for regulatory services remains largely neglected. The objective of this paper is to evaluate the usefulness of participatory geographic information system (PGIS) methods for demand assessment in larger rural and agrarian contexts by identifying spatially explicit demand patterns for ES, thereby enlarging the body of participatory approaches to ES-based land use management. Accordingly, we map, assess, and statistically and spatially analyze different demands for five ES by different stakeholder groups in agricultural landscapes in three case studies. The results are presented in a stakeholder workshop and prerequisites for collaborative ES management are discussed. Our results show that poor correlation exists between stakeholder groups and demands for ES; however, arable land constitutes the highest share of the mapped area of demands for the five ES. These results have been validated by both the survey and the stakeholder workshop. Our study concludes that PGIS represents a useful tool to link demand assessments and landscape management systematically, especially for decision support systems.

Purpose: to study the indicators of melt water runoff from arable land of various compaction and to assess its quantitative and qualitative characteristics based on long-term data. Materials and methods. Studies of the intensity of melt water runoff were carried out in the Azov zone of Rostov region in the period 1964–2018 by a number of researchers, including the author of the article. Results. The runoff indicators for a 55-year period are characterized by significant fluctuations. Analysis of long-term data revealed that the indicator of melt water runoff rate from loose arable land for the period 1964–2018 averaged 9.0 mm/year and on compacted arable land averaged 17.5 mm/year. On loose arable land, the maximum runoff rate for a 55-year period is 25.3 mm, on compacted arable land it is 47.3 mm. As a result of the analysis of the data, it was revealed that the average water reserve in snow on the surface of the fall-plowed land is 43.7 mm, and 48.7 mm on the winter wheat sowing. In general, for two agrophonies, the runoff indicator for the period 1964–2018 was most often characterized as weak and very weak only on loose arable land. Calculations of statistical indicators of runoff data revealed that they are not uniform, for example, the coefficient of runoff variation from loose arable land was 115.4 %, and from compacted arable land 70.4 %, with a coefficient of variation above 33 %, the aggregate is considered heterogeneous. Rostov region, having a large agricultural potential, is experiencing significant problems from the impact of negative natural processes, among which one of the first places belongs to erosion processes. Conclusions. In the course of generalization of long-term data on melt water runoff from arable land of varying degrees of compaction, indicators that made it possible to plot the flow availability curves were obtained. The use of the results obtained makes it possible to predict the occurrence of runoff of various intensities and thereby prevent its negative impact on agricultural land with the minimal material costs.

Questions of creation the environmentally friendly agricultural land as a priority direction of greening the economy of regional system are considered. The role of environmentally friendly land as part of a balanced agricultural nature, quality characteristics which are the basis of agro-ecosystems preservation, productivity increasing, prevent degradation and agricultural landscapes restoration is analyzed. The article presents the issue of improving soil quality continues needs to be urgent. In particular, the task of improving the quality of agricultural land and considering the qualitative characteristics as an object of management remains unresolved, which necessitates further systematic research in this direction. The purpose of the article is to substantiate the essence of soil quality management, the creation of land masses with appropriate soil characteristics as a means of obtaining safe products of standardized quality, maintaining the quality of the natural environment, preventing its degradation and using innovative industrial technologies in alternative agricultural systems. It is substantiated that qualitative soil properties and fertility are inextricably linked. The processes of soil formation and soil fertility are determined by a number of natural factors and the nature of economic activity, which affects not only the arable layer but also deeper soil horizons, as well as groundwater and groundwater. The optimal parameters of fertility indices should be established for each type of soil, ie they can vary according to the fertility patterns as a combination of soil properties and modes that ensure the productivity of the land, the high quality and safety of the agricultural products derived from them. It is determined that the management of ecological agriculture will facilitate the creation of land uses with special characteristics, which are achieved through the implementation of the general laws of agriculture and a number of principles, among which the principles of environmental orientation are combined with the principles that facilitate their implementation.

Agricultural lands of the Russian Federation are intensively subjected to degradation and desertification as a result of irrational economic activity, which, against the background of unfavorable climatic factors, led to the destruction of natural ecosystems, degradation of the soil cover and ultimately to the creation of the unfavorable ecological environment. About 65 % of 130 million hectares of arable land, are exposed to water and wind erosion. Only by water erosion, 10 % of arable land lost 30–60 % of fertility and almost 25 % lost 10–30 %. As a result of deflation 25million hectares of agricultural land in the European part of the Russian Federation are degraded to varying degrees. The concept of the anti-degradation arrangement proposes to use environmental-economic geoinformational monitoring. Within the framework of this approach, the development of cartographic and mathematical models in three time environments is proposed: pre-agricultural, modern degraded, and certainly improved condition. The ecological and economic analysis makes it possible to synthesize information flows and analyze the most important degradation processes. The most important tool for implementing ther adaptive-landscape anti-degradation arrangement of agricultural landscapes is precision farming, which consists of several subsystems: decision-making, monitoring, agronomic techniques, specialized equipment, etc. Computer technologies and telecommunications allow to speed up and optimize production by combining technology and people, which helps reduce costs. Precision agriculture is impossible without using modern advances in collecting, processing and storage of various, often heterogeneous, agricultural information.
