Oscillatory spatial and temporal variability of precipitation in Polissia and Forest-Steppe and the impact of agricultural landscape transformation

The territories of Polissia and Forest-Steppe are of great importance to Ukraine, offering significant potential for the advancement of agriculture and forestry. In light of the pressing issue of global climate change, it is imperative that the active economic utilisation of these territories be guided by a commitment to the maintenance of ecological systems and the sustenance of ecosystem functions. The objective of this article was to ascertain the patterns of both spatial and temporal precipitation variability and to establish the impact of anthropogenic land transformation as a consequence of agricultural production. Within the study area, the average precipitation level was 625±68 mm and ranged from 535 to 1,160 mm. During the study period (1960-2023), there was a trend of increasing and decreasing precipitation. The southeast of the region was characterised by a decreasing trend in precipitation, while in the northwest and north, the time trend showed an increase in precipitation. Precipitation in the Carpathian region is much higher than in other parts of the territory. The presence of an oscillatory regularity in precipitation rhythm allows for consideration of two practical aspects: the possibility of forecasting future precipitation dynamics based on available information from previous years, and accounting for the fluctuating precipitation dynamics when recommending optimal crop rotations and selecting the most suitable range of crop varieties for cultivation
