Assessment of the Soil Cover in the Dried Aral Seabed in Kazakhstan and Climate Change in the Region

The dried Aral seabed is a newly developed anthropogenic salty desert (Aralkum). It is a catastrophic region for all of Central Asia, including Kazakhstan. This research allows us to obtain a better understanding of the transported material properties from the dried seabed during soil deflation caused by storms. The seabed is mainly flat plains and undulating ridge plains. The main soil types of the desert are saline soils, including different kinds of solonchaks and sands. The soil texture is sandy loam, and the soils are calcareous and alkaline (pH 7.7–8.6). Carbonates in the soils range from 4.86 to 8.51%, and the soils are susceptible to deflation processes. The humus content in soils is very low (<?2%). The soil cover is contaminated with heavy metals such as Cd, Zn, Cu, and Mn, which can lead to air/water pollution and vegetation/soil degradation. The monitoring of climatic parameters has indicated aridification in the region. The mean monthly temperature and potential evaporation in the region increased by 2 °C (23.81%) and 76 kg m?2 (7.81%), respectively, from 1986 to 2020.
