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.

This article discusses the patterns of the dynamics of the underground part of the ephemeral-wormwood semi-desert of the Kura-Araz lowland in conditions of climate change. It was found that regardless of the plant development phase, season of the year and climate change conditions in different years, the ratio of productive and unproductive roots of plants remains at a certain level. The authors of the article determine the objects and methods of research that were conducted by them in different time periods in different climatic conditions. The authors provide figures and data (in tables) illustrating repeated experiments and observations. On the basis of scientifically grounded descriptions, the authors come to the conclusion that with the deepening into the soil, a decrease in the root mass in plant communities occurs with a pronounced regularity.

The assessment of the global state of desertification highlights the need of information describing global extension of arid degradation and damage it causes. In the context of climate warming, which is noticed at the present time, all new regions will be exposed to drought, weakening the stability of the degraded lands. However the frequency of droughts increases in arid regions with high intensity. The efforts of scientists and practitioners have been reflected in the journal «Arid ecosystems» over the past 25-years, allowed us to obtain final information about the mechanisms of degradation of soils, vegetation and wildlife. Based on the scientific achievements in anthropogenic dynamics of desertification processes and resource potential of individual components of arid ecosystems, it is necessary to make a reasonable approach to the strategy and identify methods for implementing the presented concepts, programs and projects. Generalization of theoretical positions of productivity restoration, stability of a soil cover allowed to present fundamental research of the world arid lands as an independent concept of «green economy». Its main specific feature is the differentiation of human impact: natural and medical-biological. The last aspect includes the assessment of the social situation of people living in conditions of increasing droughts, dry spells and climate warming.
