The article highlights the stages of work during which the impact of individual terrain properties on arable farming was identified. The possibility of using digital elevation models (DEM) to identify those characteristics that can have a significant impact on such lands was studied. Findings have been made about the relationship between these features and the sites, and their place among other arable land features has been determined. The initial step was to select the baseline data for the area under study and obtain it in the form we needed. Here, techniques for automated DEM acquisition are being developed. At the next stage, individual terrain characteristics, complexity of their acquisition and ranking by importance for this methodology were considered and analyzed. At the final stage the analysis of agricultural lands, their connection with the relief and its characteristics was carried out, practical conclusions were drawn and recommendations were made based on them. It should be noted that the study area — the Vindrei River basin — is very illustrative for showing the advantages of the technology being developed. Its territory is occupied both by extensive agricultural land and forest areas. During the development of the methodology it was important to demonstrate the possibilities of using the technology in the field of nature management and improving economic efficiency of the area.

Central Chernozem is one of the largest agricultural regions in Russia. As a result of the long period of natural resources use the anthropogenic load on agricultural lands is increasing. The result of agricultural nature management is the increase of land degradation processes. Voronezh Region has a high agro-climatic potential, most of the territory is occupied by agricultural land, arable land prevails among them. Soil degradation is the most acute problem. There is a need to assess the impact of agricultural natural resources use on land resources of the region. Modular coefficients for assessment of geochemical impact of agriculture and animal husbandry on agricultural systems are proposed. The developed factor is a tool for identification of negative land use processes and environmental problems. The article deals with the issues of ecologically oriented, scientifically grounded strategy of agricultural nature management. Ecological approach to assessment of soil quality in the future will develop a strategy for balanced land use. The article has a scientific and practical character and is aimed at the development of methods of ecological assessment of soil quality. The proposed methodological approach identifies destructive processes in soils. For ecologically oriented strategy of development of regions it is important to define maximum allowable agricultural loads for preservation of sustainable 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.

This study examines the impact of agricultural land use change into a petroleum mining area to farmers’ socioeconomic conditions around petroleum mining project area in Gayam District of Kabupaten Bojonegoro. The analyses used a mix method, using both quantitative and qualitative approaches. The quantitative approach is used to determine the impact of agricultural land use change on the social and economic aspects with the respondent farmers were supported with a scoring method to determine the condition of socioeconomic vulnerability of farmers, while the qualitative approach carried out through in-depth interviews to some informants who have been affected by the project. The results shows that the presence of the petroleum mining industry has not had a positive impact yet on the farmers’ socioeconomic conditions. By the 700 hectares of agricultural land conversion, the agricultural production capacity of the area tends to decrease, including by the decreasing of the productivity of some agricultural land in a radius of 500 m from the fenceof the mining area as they are affected by the fence’s spotlight. The farmers' income also tends to decrease because of the decreasing of their working hours as the big loss of agricultural land in the area. As a result, many farmers should work outside of the area to search replacement of the arable land. These situations lead to a moderate condition of social and economic vulnerability for the farmers, especially for those who still have sufficient assets to meet the needs of their economic.

In the Non-Black Earth Zone of Russia, since the 90s of the last century, the number of tractor and other agricultural machinery has sharply decreased. If in 1990 there were more than 30 thousand tractors of various capacities in the Tver region, then by 2020 there are 4 thousand tractors left in collective agricultural organizations, and approximately the same number of tractors are in private farms. The reduction occurred more than 8 times, with the remaining equipment having an average age of over 12 years. The renewal of tractor equipment in recent years has been happening at a rate of 1-2% per year, at the same time, 7-8% of the remaining tractors are written off annually. Directly connected with such dynamics is the reduction of acreage, which decreased by about 10 times, to 120 thousand hectares. And only in recent years there has been an increase in cultivated areas to 278 thousand hectares. At present, 551 thousand hectares of agricultural land are used for the production of agricultural products, that is, from 2,575 thousand hectares. Half of the agricultural land is arable land. More than 300 thousand hectares of arable land are idle, overgrown with forest, bushes, hogweed. The age of vegetation, forests on abandoned arable land reaches 10 years. In the near future, most of these lands may be completely decommissioned.

The subject of the study presented in this article is the economic relations arising due to the progress of the urbanization that leads to changes in agricultural production. For a long time in Russia a reduction of agricultural land, arable land and crops takes place. One reason for this is the global progress of urbanization. Changes in agricultural land use occur across the country however this process is uneven in different regions. Among all regions Moscow and Moscow region significantly stand out. The study showed that in the more urbanized regions of the country reduction of the agricultural land and changes in agricultural land use are greater than in less urbanized ones.

In the context of the rapid development of renewable energy in Germany in the last decade, and increased concerns regarding its potential impacts on farmland prices, this paper investigates the impact of wind energy and biogas production on agricultural land purchasing prices. To quantify the possible impact of the cumulative capacity of wind turbines and biogas plants on arable land prices in Saxony-Anhalt, we estimate a community-based and a transaction-based model using spatial econometrics and ordinary least squares. Based on data from 2007 to 2016, our analysis shows that a higher cumulative capacity of wind turbines in communities leads to higher farmland transaction prices, though the effect is very small: if the average cumulative capacity of wind turbines per community doubles, we expect that farmland prices per hectare increase by 0.4%. Plots that are directly affected by a wind turbine or part of a regional development plan, however, experience strong price increases.

This study focuses globally on the effects of desertification and drought on agricultural lands. Desertification, which shows more its effects from region to region all over the world and particularly on certain continents, contains factors that will disturb the human future. One of these negative factors is the risk of creating food vulnerability by directly damaging agricultural areas. The risk of desertification reducing the quality of human life and threatening other living plants and habitats is a very important issue that should be highlighted by the international system. In this context, the study draws attention to the negative impact of global desertification, as well as the reduction of agricultural and arable land and the risks of declining crop yields. Among other problems caused by desertification, the study emphasizes socio-economic instability due to migration and climate-related conflicts, world hunger and lack of grain and food. In the study, the literature on global desertification, drought and arable agricultural land was searched and selected source information from the literature is included in the study. In addition, the study was supported by maps, graphs, and tables, as well as desertification researches and analyzes. Due to the limitation of the pages, other factors, such as global warming triggering desertification, have not been addressed, and environmental issues, which are directly damaged by desertification other than arable agricultural areas, are excluded from the field of this study. Keywords: Desertification, drought, arable agriculture, food insecurity, hunger, vulnerability

Goal. Study of peculiarities of growing pine stands and prospects of their use in agroforestry of Zhytomyr Polissia on the example of agricultural lands of Malyn Vocational College. Methods. Field, laboratory, analytical, statistical. Results. On sod-podzolic sandy soils of Zhytomyr Polissia pine seedlings after three years of cultivation were 55.7 ± 3.43 cm in height. The maximum increase in height was observed during the third year of cultivation of the plantation, when at the beginning of the growing season with herbicide Targon Plus the impact of cereal vegetation reduced to a minimum, resulting in improved seedling growth conditions. The high preservation of pine plants and their intensive growth allow us to make optimistic forecasts about the feasibility of growing them as a forest component of agricultural landscapes, especially given the presence of biotically stable 15-year-old pine plantations created by similar agricultural techniques. They were laid at an initial density of 7.1 thousand seedlings per 1 ha, and later thinned to 2982 and 1691 plants/ha, respectively. With almost the same productivity indicators, higher tree height (by 17.0%) and larger average diameter (by 23.8%) allow thinner plantations to have a more positive impact on adjacent agricultural lands, grow more intensively and have higher productivity in the future. This indicates the expediency of pine plantations in the region of research as a forestry component of agrolandscapes a density at the age of 15 years of about 1700 trees per 1 ha.

The article presents an ecological and geographical analysis of the current state of land resources. The structure of land resources in UTC (United Territorial Community) is dominated by lands of agricultural and forestry use. They occupy the largest areas - 67072.3 hectares, 40004.8 hectares and their share in the structure of the land fund is 57.8%, 34.4%, respectively. The structure of agricultural lands of the district is dominated by agricultural lands, namely arable land. Its area is 67072.3 hectares (97.3%) The largest area of agricultural land is concentrated within the central part of the district. The largest area in the structure of agricultural land is occupied by arable land - 2500 - 3570.8 hectares. In the eastern and south-eastern parts of the district the share of arable land in the structure of agricultural lands is the highest (more than 70%). The share of pastures and hayfields in the structure of agricultural lands is 18.2% and 16.8%, respectively. The smallest share in the structure of lands of perennial plantations (1.6%). The largest areas of hayfields and pastures in the northern and northeastern part of the district, which is due to the natural features of the territory. Peculiarities of forestry use of land resources on UTC area are analyzed. Lands covered with forest vegetation there are unevenly distributed and are mainly subordinated to Brody Forestry. The largest areas of forestry land in the northern and southern parts of the district. Forests in the northern part are located within Male Polissya. Here in the area there is the highest forest cover (45 - 67%). Forest cover in the southern part of the district is 45 - 67%. The structure of lands occupied by forest vegetation is dominated by forest areas (96.0%), including covered with forest crops (71.0%) On the basis of the defined indicators the analysis of ecological stability of lands in UTC is carried out, also the anthropogenic loading on agricultural lands of the area is defined. This figure depends on the area of land of different species. Using the method of Shyshchenko P. H. (1982) we have determined the anthropogenic load on the agricultural lands of the district. This figure depends on the area of the land of different species. Within the district there are spatial differences in this indicator. The greatest anthropogenic load on agricultural land is in the central part of the district. Here the anthropogenic load is more than 6.6 (strongly converted). In the north-western part of the district this indicator is the lowest: 5.2-5.3. On the territory of other village councils agricultural lands are moderately transformed (6.1 - 6.5) The results of the study of the ecological condition of the land resources of the district are presented. The level of plowing, agricultural development of the district is analyzed. The central and southern part of the district is characterized by an unbalanced structure of land use, as there is a fairly high rate of plowing of agricultural land. The share of arable land here is more than 70% of the total area of agricultural land. The average value of this indicator is around 57.7%. The highest agricultural development is in the central part of the district (except for Brody town territorial community), and in the southern part (more than 60%). The maximum indicators of agricultural development are - 86.8-91%. The ecological condition of the land resources of the district was assessed and five groups with different levels of this indicator were identified. The ecological condition of land resources varies from optimal to catastrophic, depending on the ratio of arable land (R) and the share of ecological and stabilizing lands (ESL). Optimal and satisfactory ecological condition of land resources in the region on the area of 40.6%, critical - 25.7%, crisis - 20.4%, catastrophic - 13.3% Land resources are one of the most important resources of the district. In modern conditions, productive agricultural lands should be involved in intensive agricultural cultivation, and the rest should remain in a natural state, which will ensure ecological sustainability and balanced nature management. Key words: land resources, agricultural lands, agricultural development, ecological condition, ecological stability.


In order to address food security problems in Russia, insufficient attention is paid to the development and implementation of innovative technologies for the enrichment of agricultural lands and plants growing on them. Such technologies make it possible to purposefully bring the necessary micro and macro elements to agricultural plants, while ensuring, in turn, a significant increase in the consumer quality of agricultural products. The article discusses innovative technologies for the enrichment of agricultural land and plants growing on them, the use of which will increase the consumption of agricultural food raw materials from each hectare of arable land, as well as the quality of functional food products produced from it. This will increase the competitiveness of fortified products in the domestic and foreign markets and make an important contribution to improving the food security of the country. The analysis showed that one of the important directions of innovative developments and patents in the field of enrichment of agricultural lands and plants growing on them is the solution to the problem of providing the population of Russia and the world with regulatory requirements for micro and macro elements: iodine, selenium, magnesium, calcium, manganese, zinc, etc., as well as in vitamins by pre-sowing, root, and foliar enrichment of cereal, fruit-bearing and vegetable crops in open and in closed ground. All this, in turn, will help to provide the country's population with high-quality food products derived from enriched agricultural raw materials and increase its competitiveness in the domestic and foreign markets.
