Nowadays, agricultural production is highly exposed to the increasingly frequent extreme environmental events (drought, alternating inland water). In Hungary, the South Alföld Region is the driest area in the country. In 2022, 200 millimeters of precipitation fell in this area instead of the average annual precipitation of 500-550 millimeters, which results in a precipitation deficit of 300-350 millimeters. Adapting to such extremes means technical and financial difficulties for farmers. An accurate knowledge of forecasting systems (meteorological forecasts) and local natural systems (topography, soil properties, groundwater properties, vegetation cover) would make adaptation easier. The long-term, seasonal changes in the groundwater level we can be said to be constant, but if we take some examination, we can determine that this is not the case. It is difficult to identify the causes of fluctuations only by observing short-term water level records. The long-term groundwater-level records in the Hármas-Körös Sub-catchment area, were thoroughly analysed along with the results from the cumulative rainfall, and knowing the prevailing soil type. With our analysis, we assess the trends of the groundwater level (by examining the water levels of eight groundwater monitoring wells) and expected changes by examining the twenty-year monthly average data series of the sub-catchment area.
