Ganiyeva S.A., Gurbanov E.A. SEASONAL DYNAMICS OF THE UNDERGROUND PART OF THE EPHEMERAL-WORMWOOD SEMI-DESERT OF THE KURA-ARAZ LOWLAND IN MODERN CLIMATIC CONDITIONS // Arid ecosystems. 2021. V. 27. № 1 (86). P. 54-61. | PDF
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.
