Abstract

The-Trans Tisza Regional Water Directorate area is one of the regions of the Carpathian Basin most exposed to the adverse effects of drought on agriculture. Climate change here increases the likelihood of extreme weather events. It is also true that the frequency of drought and extreme precipitation periods is increasing. A better understanding of all this is essential for water planning and control of water management to create conditions of adaptive, precision farming. This paper's research used daily rainfall data from 16 Trans-Tisza Regional Water Directorate hydro-meteorological stations between 1964 and 2022. We have shown that the change in extreme precipitation events is not statistically significant for the aggregated data of the 16 stations between 1964 and 2022. However, significant changes were detected after splitting the data series into two periods of equal length (1965-1993; 1994-2022) for further comparative statistical analysis. We showed a significant increase in the frequency of periods without precipitation of at least 25 days, according to the data of the hydro-meteorological station in the area of Nagybajom municipality. This, combined with the area's soil conditions, suggests that precision irrigation management is becoming essential to achieve desirable agricultural yields and that, where appropriate, it may be necessary to drain low-lying areas at risk of inland flooding.
