TENDENCIES OF CLIMATIC INDICES IN THE ROMANIAN IRRIGATION SYSTEMS

The aim of this investigation was to evaluate the tendencies of climate aridity of areas where irrigation systems are present, based on meteorological parameters such as precipitations, potential evapotranspiration and water deficit as expressed by the average value of the ratio between precipitation and potential evapotranspiration (P/ETP). The impact of climate changes was done by comparing the time periods of 1961–2000 with 2001–2016, at NUTS5 level where there is potential for crop irrigation. The results showed that for the time period of 2001–2016, the mean values of precipitations decreased down to399 mm, and the potential evapotranspiration increased up to716 mm. Therefore, the water deficit expressed as average value of the ratio P/ETP decreases from 0.594 to 0.557. There is a higher water deficit in most areas where the irrigation systems are present, and, therefore, the near future trend is to increase the water deficit over time
