In Kazakhstan, agricultural land has been degraded for decades, leading to an overall decline in crop yields. The purpose of the study is to conduct an environmental assessment of the current state of Kazakhstan’s soils to increase crop yields using soil protection methods. The following methods were used in the study: cartographic, analysis and synthesis, systematization, abstraction, specification, and forecasting. Agriculture accounts for 86% of Kazakhstan’s land. Active land use has led to various forms of degradation, resulting in 90 million hectares of eroded soils, of which 29.3 million hectares are almost completely eroded. In 2023, the average yield of grain crops was 9.3 c/ha, oilseeds – 7.1 c/ha, and vegetables – 275.4 c/ha. It is noted that the yield of grain crops in 2023 is 28% lower than in the previous period of 2020-2022, despite the increase in sown areas. Drought and soil degradation are the main reasons for the decline in grain yields. It is noted that the main biological constraints to grain production are soil drought, windstorms, degradation and extreme temperatures, especially in rainfed irrigated farming systems in arid lands such as southern Kazakhstan. In the northern and central parts of Kazakhstan, agricultural land is dominated by black and chestnut soils, and in the south by brown semidesert soils. The largest areas of eroded agricultural land are located in Almaty, Atyrau and Turkestan regions – over 30%, and the smallest – in Akmola, Karaganda, Kostanay and North Kazakhstan regions – 5%. Productive grain growing requires soil monitoring for the main mobile elements that affect plant yields. The average values for the Republic of Kazakhstan are: nitrogen content – 37.5 mg/kg, phosphorus – 16.8 mg/kg, potassium – 419.5 mg/kg, humus – 2.8%. The practical significance of the study is to expand and supplement the theoretical basis of research in the field of soil degradation, and the results obtained are proposed for a comprehensive environmental assessment of soils in Kazakhstan

“…It helps to separate the common and distinctive features and properties of the studied objects and their development processes. GIS applications include both hardware and software components (Cheshire, 2011, p. 55;Darbayeva et al, 2020). They combine various types of information, among them cartographic data presented in the form of a map, and may include information such as the location of the hydronomic names.…”

The article analyzes scientific approaches to the grouping of toponyms according to the geographical principles based on the materials of the Zhambyl region and comprehensively examines hydrographic terms. The importance of the study is due to insufficient work on the hydronymy of the Zhambyl region and the need to develop this direction in Kazakh science. The aim of the study is to group the hydronyms of the Zhambyl region based on geographical principles. The study used cartographic, statistical and GIS methods. Whilst analyzing hydrographic objects, 177 names of rivers were identified which were formed with the participation of indicator terms related to rivers. They were classified and grouped into the most common terms in the names of rivers such as the term sai 57%, the term su 25% and the term ozek 16%.

“…The relevance of the topic is determined by the increasing demand for forest recreational resources of the West Kazakhstan region. As a result of long-term research , it was revealed that 630 species of vascular plants belonging to 72 families and 309 genera grow in the floodplain forests of the Ural River within the West Kazakhstan region (Ramazanova et al, 2022;Ramazanova et al, 2020). The largest families are Poaceae -72 species (11.4%), Asteracae -65 species (10.3%), Fabaceae -38 species (6.0%), Rosaceae -37 species (5.9), Lamiaceae -36 species (5.7%), Caryophyllaceae -35 species (5.6%), Brassicaceae -29 species (4.6%), Chenopodiaceae -25 species (4.0%), Apiaceae -24 species (3.8%), Liliaceae -24 species (3.8%), etc.…”

Thus, in the floodplain forests, the presence of widely distributed families, such as Poaceae, Suregaceae, Scrophulariacae, Polygonaceae, which are distributed throughout the floodplain of the Urals, can be traced.…”

The relevance of the topic is determined by the increasing demand for forest recreational resources of the West Kazakhstan region. The forests of the West Kazakhstan region are under the influence of recreational activity, which is growing every year and leads to the transformation of the natural environment. The purpose of the study is to determine the influence of recreation on the processes of soil erosion in the forests of the West Kazakhstan region. An increase in the recreational load and the steepness of the slopes leads to degradation of the forest floor and grassy cover. The remnants of these materials move downhill under the influence of visitors, and the soil surface is compacted. The porosity coefficient of the upper soil layer decreases as recreational loads increase. This leads to a decrease in soil water permeability and an increase in surface water runoff. The study showed that the runoff coefficient, the air-dry mass of the forest floor and the porosity coefficient are closely related. These relationships characterize an increase in the water runoff coefficient with a decrease in the air-dry mass of the forest litter and the porosity coefficient. In the field in 2023, based on the morphological description of the profiles, the degree of soil erosion in the selected woodlands was determined.
