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

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.

Near Future

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.

Abstract. Surface runoff represents a major pathway for pesticide transport from agricultural areas to surface waters. The influence of man-made structures (e.g. roads, hedges, ditches) on surface runoff connectivity has been shown in various studies. In Switzerland, so-called hydraulic shortcuts (e.g. inlets and maintenance manholes of road or field storm drainage systems) have been shown to influence surface runoff connectivity and related pesticide transport. Their occurrence, and their influence on surface runoff and pesticide connectivity have however not been studied systematically. To address that deficit, we randomly selected 20 study areas (average size = 3.5 km2) throughout the Swiss plateau, representing arable cropping systems. We assessed shortcut occurrence in these study areas using three mapping methods: field mapping, drainage plans, and high-resolution aerial images. Surface runoff connectivity in the study areas was analysed using a 2 × 2 m digital elevation model and a multiple-flow algorithm. Parameter uncertainty affecting this analysis was addressed by a Monte Carlo simulation. With our approach, agricultural areas were divided into areas that are either directly connected to surface waters, indirectly (i.e. via hydraulic shortcuts), or not connected at all. Finally, the results of this connectivity analysis were scaled up to the national level using a regression model based on topographic descriptors. Inlets of the road storm drainage system were identified as the main shortcuts. On average, we found 0.84 inlets and a total of 2.0 manholes per hectare of agricultural land. In the study catchments between 43 and 74 % of the agricultural area is connected to surface waters via hydraulic shortcuts. On the national level, this fraction is similar (54 %). These numbers suggest that transport through hydraulic shortcuts is an important pesticide flow path in a landscape where many engineered structures exist to drain excess water from fields and roads. However, this transport process is currently not considered in Swiss pesticide legislation and authorisation. Therefore, current regulations may fall short to address the full extent of the pesticide problem. Overall, the findings highlight the relevance of better understanding the connectivity between fields and receiving waters and the underlying factors and physical structures in the landscape.

The paper studies the issue of the use of disposed agricultural land through the example of LLC “Alliance-agro in Sengileevsky district of the Ulyanovsk region. The authors consider the grounds for cultural and technical work and provide the results of a survey of unused arable land on the farm. A technology for the development of disposed agricultural land is proposed. Everyone knows that agricultural land is of particular importance as a means of agricultural production and is the second largest category of land in the unified land fund of the Russian Federation in terms of area, which includes the best and fertile lands making up the heritage of the country. Despite the fact that the schemes for the use of agricultural land are developed, many questions of a theoretical, methodological and applied nature need to be improved, since this is associated with incessant changes in the legal and organizational systems of land use. As a result of irrational use of land, degradation, littering, overgrowing with trees and shrubs of agricultural areas occurs. These processes lead to the fact that fertile lands are withdrawn from circulation. Our research is aimed to solve the problems in the field of the improvement of the cadastral registration of lands, the process of the organization of rational land use, as well as the most effective use of unused lands overgrown with trees and shrubs. The solution to this problem will help the rational transformation of the agricultural land use system and increase in their efficiency. Moreover it will help to solve the problem of the involvement of unused land in agricultural production and increase the efficiency of cadastral registration of agricultural land. As a result of the land clearing proposed by the authors, the sites of this object will be put into agricultural circulation, where any zoned agricultural crop can be grown from the first year of development in case of a favorable water-air regime in the root layer and complex agrochemical cultivation.

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.

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.

Long-term land changes are cumulatively a major driver of global environmental change. Historical land-cover/use change is important for assessing present landscape conditions and researching ecological environment issues, especially in eco-fragile areas. Arable land is one of the land types influenced by human agricultural activity, reflecting human effects on land-use and land-cover change. This paper selected Zhenlai County, which is part of the farming–pastoral zone of northern China, as the research region. As agricultural land transformation goes with the establishment of settlements, in this research, the historical progress of land transformation in agricultural areas was analyzed from the perspective of settlement evolution, and the historical reconstruction of arable land was established using settlement as the proxy between their inner relationships, which could be reflected by the farming radius. The results show the following. (1) There was little land transformation from nonagricultural areas into agricultural areas until the Qing government lifted the ban on cultivation and mass migration accelerated the process, which was most significant during 1907–1912; (2) The overall trend of land transformation in this region is from northeast to southwest; (3) Taking the topographic maps as references, the spatial distribution of the reconstructed arable land accounts for 47.79% of the maps. When this proxy-based reconstruction method is applied to other regions, its limitations should be noticed. It is important to explore the research of farming radius calculations based on regional characteristics. To achieve land-system sustainability, long-term historical land change trajectories and characteristics should be applied to future policy making.
