Anthropogenic impact on agricultural land in the Republic of Kazakhstan
2022

The purpose of the article is to consider the features of the anthropogenic impact on agricultural land in the Republic of Kazakhstan (RK). The article deals with the current problem of agricultural land degradation, and desertification in Kazakhstan, where one of the causes is the anthropogenic activities of the population and the aridity of the country's climate. Most of the territory of Kazakhstan is located in conditions highly vulnerable to anthropogenic desertification when in combination with natural factors of desertification the ecological situation is sharply deteriorating. Another cause of land degradation is urbanization and intensive degradation of desert habitats — unsystematic road network, regulation of river flows, illegal cutting of saxaul for firewood for sale. As a result of urbanization and intensive agricultural development of the foothill strip in the south and east of the country, the natural vegetation cover is highly disturbed. Roads, pipelines, and power lines, which are being laid at an increasing rate, have a great impact on the fauna. The area of land occupied by mining enterprises is steadily growing. In the last 10 years, the areas of oil and gas extraction, development of uranium ores, etc. in Western Kazakhstan, the Eastern Caspian Sea region, the Betpakdala desert, etc. have been sharply increasing. As a result of insufficiently thought-out land management from water erosion 5.6 million hectares of arable land was affected and grain yield was reduced by 20–30%. Degradation of agricultural lands, including pastures, is 30–50% and higher % in 9 of 14 regions of Kazakhstan. The use of the existing model of agricultural development of raw materials leads to inefficient economic development and constantly increasing pressure on ecosystems. The soil in Kazakhstan is very vulnerable, as it is comprehensively affected by various anthropogenic factors that lead to the constant deterioration of its quality. Soils near the Aral Sea and the Caspian Sea are subjected to the most intensive degradation, as wind erosion is widespread there.

The search of effective methods of agricultural land protection from soil erosion under conditions of land relations’ reform in Ukraine is a complex ecological and economic issue requiring a system approach to its solution, adequate organizational and economic support and scientific argumentation. The topicality of the research is based on the importance of the problem of arable land protection from soil erosion, and its solution is related to ecologically safe land utilization keeping to the principles of balanced development of land management. The aim of the research is to develop scientific basis for the recommendations how to improve the system of erosion-safe agricultural land management under conditions of reforming land relations in Ukraine. The article presents scientific fundamentals of organization of erosion-safe land management in the context of the balanced development of nature management, analyses conditions of utilization and protection of land in erosion-unsafe landscapes; develop scientifically grounded recommendations as to improvement of a system of erosion-safe agricultural land management at a local level. In the process of the investigation a combination of methods were used: monographic, induction and deduction methods, system analysis, cartographic, experimental projecting. A contour organization of the territory is recommended to apply to protect arable land from soil erosion. Reimbursement of money payments and tax privileges can motivate landowners and land users to introduce anti-erosion measures. It is required to consider use value and non-use value of land resources in the process of their estimation for land payments.

Analysis of the condition of the Agila Dune is presented in this Article. The analysis is based on data collected during accurate geodetic measurements using LIDAR technology. The current state of the Agila Dune was compared to the data of the previous year's LIDAR points in order to ensure the reliability and value of the research. In the course of the study, eleven cross sections were compared by height differences with previous year‘s measurements. The condition of the Agila Dune was found to be the worst in three cross sections. First cross section‘s erosion measured at 13,98 meters, erosion in the fifth cross section – 9.90 meters, and erosion in the eighth cross section – 11.34 meters. The main reasons for the deterioration of the natural values of the Kursiu Nerija National Park are climate, wind, high visitor flows and the persistent failure to carry out comprehensive research. Therefore, in order to preserve these unique natural values, it is important to collect large-scale and high-precision data on the status of these values, to systematize, to analyse and take appropriate protective measures.

As result of land reform in Russian Federation the public administration of agricultural land has been totally transformed. Land reform was carried out in order to solve problems in the sphere of agriculture, housing construction, ecology, creating a plurality of land ownership forms, introducing land use payments, etc. The decision to cancel monopoly of state ownership in land and to create institution of private property was made. The land redistribution projects for each farm were made, where stock of shares, stock of land redistribution and stock of land administered by previous soviet village councils was represented. The example of the Samara region was used to develop mechanisms for transfer of public land to private ownership. Currently, the situation with use of the land in many agricultural enterprises can be considered as unsatisfactory due to unsystematic economic activity − there are no or are not implemented scientifically based crop rotations, natural soil fertility is not taken into account, there is no modern cartographic material indicating the size of the fields, degree of slope and degree of erosion. Significant deterioration of the agro-ecological situation and the spread of negative processes on arable land require changes in national land policy and development of comprehensive measures to organize rational use of land. In the near future, a significant modernization of national and federal land legislation is planned, which will affect all subjects of the Russian Federation in terms of the management and use of agricultural land.
