Abstract. In irrigated lands of the Aral Sea Basin, salt-affected areas are increasingly rising and 
this negatively impacts agricultural development and food security in such countries located in the 
basin. Drivers, increasing salt-affected areas, are assumed to be climate change, unregulated high

groundwater levels and its increased mineralization, poor functioning of the collector-drainage 
system, and insufficient compliance with agro-technical requirements. These drivers, in turn, lead to 
the withdrawal of arable land from agricultural purposes and a significant drop in crop yields. This is 
especially the case in the irrigated areas of the lower reaches of the Amu Darya and Syr Darya rivers, 
including Uzbekistan, southern Kazakhstan, and Turkmenistan. In regard to Uzbekistan, the research 
on soil salinity assessment was conducted in the irrigated areas of the Syrdarya province by analyzing 
raw data derived from traditional methods from 2000 to 2015, as well as from 2016 to 2019 using the 
integrated traditional and GIS-based methods. Based on the results of field and laboratory studies on 
spatio-temporal soil salinization changing dynamics in the province, such maps were created to 
investigate similar spatial patterns on soil salinity over time by using the GIS-based interpolation 
method.
The results of the research work revealed that soil salinity highly depends on soil conditions and 
its relief, and climatic factors of the province. Regarding the main findings of the research, 
agricultural specialists and farms are distinctly encouraged to take the following measures to address 
the actual soil salinity condition in the irrigated areas of the province: targeted and wisely use of 
irrigation water; exist drainage networks are in perfect working condition and monitoring their full 
effective operation; and, lastly, accelerating the integration of innovative GIS technologies into 
traditional methods.
