Anthropogenic impact on agricultural land in the Republic of Kazakhstan
2022
Zhyrgalova, Alima | Zhildikbayeva, Aizhan
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.

All land of the Republic of Belarus can be classified by categories (7 categories), types of lands (14 types), land users, forms of ownership and types of rights to land plots. The total area of land in the Republic of Belarus is 20760 thousand hectares, including agricultural land occupies 9103.0 thousand hectares (43.8%) of the total area of the republic; settlements, horticultural associations, dacha cooperatives – 849.0 thousand hectares (4.1%); industry, transport, communications, energy, defence and other purposes – 622.2 thousand hectares (3.0%); environmental, health, recreational, historical and cultural purposes – 868.7 thousand hectares (4.2%); forest fund – 8656.4 thousand hectares (41.7%); water fund – 37.3 thousand hectares (0.2%); reserve land – 623.4 thousand hectares (3.0%). The basis of the land resources used in the agro-industrial complex of the republic is arable land, meadows and land under permanent crops, which in general occupy 8387.1 thousand hectares, or 40.4% of the total area of land. The state owns 20683.6 thousand hectares (99.63%) of land, private property – 76.4 thousand hectares (0.37%) of the total area of all lands of the republic. In terms of environmental stability, the territory of the republic belongs to medium-stable territories, the coefficient of environmental stability is 0.63, and in terms of the degree of anthropogenic load – to territories with a relatively low anthropogenic load, the coefficient of anthropogenic load is 2.79.

2019
Zudilin, S., Samara State Agricultural Academy (Russian Federation) | Konakova, A., Samara State Agricultural Academy (Russian Federation)
The zones of ecological trouble cover about 15% of the territory of Russia, where the main production capacities and the most productive agricultural lands are concentrated. The Samara region is characterized by a distinct natural zonality from a typical forest-steppe in the North with a forest cover close to 30%, to an open dry steppe in the South with a natural forest cover of only 0.1...0.2%. The article presents an analysis of land use in the Samara region on the example of the Borsky municipal district. Research methods include environmental analysis and statistical data analysis.The article presents an analysis of the land use of the Borskiy municipal district. During zoning, the territory of the district is divided into the northern, central and southern parts. Assessment of environmental and economic parameters showed heterogeneity of the territory and the need for detailed consideration of climatic, soil, economic conditions in the design of landscape optimization systems, even in the municipal area. In general, the district's land fund experiences an average anthropogenic load, the ecological stability of the territory as a whole is characterized as unstable stable. In comparison with other areas of the Central MES, the municipal Borskiy district belongs to the category with an average ecological intensity with a stabilization index of 0.59 units due to the beneficial influence of the Buzuluksky area.
