Dimeyeva L.A., Salmukhanbetova Zh.K., Malakhov D.V. MAPPING RANGELANDS OF WILD UNGULATES IN THE BARSA KELMES NATURE RESERVE (KAZAKHSTAN) // Arid Ecosystems. 2022. Vol. 28. № 4 (93). P. 153-162. | PDF
The article presents a medium–scale Rangeland map of the Kaskakulan cluster area in the Barsa Kelmes Nature Reserve, where wild ungulates – kulans, saigas and goitered gazelles live. Ground and remote sensing data were used to develop the map. The author’s methodology and a set of spectral indices were used processing satellite data. Based on the interpretation of satellite images, maps of seasonal rangeland yields have been developed which were considered in calculating the aboveground phytomass. The legend to the map is a system of headings that take into account zoning, ecological and physiognomic vegetation types and soil conditions. The types of rangelands are reflected in the legend by 15 mapping units, for each the aboveground phytomass for the seasons of the year is given.The map can be used for assessment of forage resourses of the territory and determination of the permissible number of wild ungulates to maintain ecosystems in a balanced state.

Smagulov Ye.N. SPATIAL DIFFERENTIATION OF CLIMATE CHANGE IMPACT ON AGRICULTURE IN AKMOLA REGION // Arid ecosystems. 2021. V.27. № 3 (88). P. 72-80.
Long-term dynamics of average air temperatures and annual precipitation amounts confirms the reality of climatic changes that began in the 70th of the last century in the Akmola region that is one of the leading agricultural regions of Kazakhstan. Cultivation of cereals, in particular, spring wheat, which is known to be extremely sensitive to climatic and weather conditions, prevails in the structure of agricultural production of the region. Based on the analysis of climatic indicators for 1931-2019, according to the available data of meteorological stations, the intraregional features of climate change, which led to an increase in the yield of grain crops, were identified. Correlation analysis established a high dependence of yield on the climatic conditions of the warm period. With the preservation of the current level of farming culture and the continued growth of average temperatures, a decrease in yield is expected in dry-steppe and southern steppe regions of the region. In the northern steppe regions, more intense trends in climatic indicators of the cold months favor an increase in yields and an expansion of agricultural production. Further development of agriculture in Akmola region requires taking into account intraregional differences in the intensity of climatic trends. In order to avoid the negative consequences of climate change, it is proposed to introduce adaptation technologies, to diversify agricultural production, to develop organic agriculture and actively to support agricultural producers.
