The crop evapotranspiration computing is a complex matter from many points of view, but also it represents a useful parameter in hydrological and climate studies. Due to climate changes, the natural systems are coming to be negatively affected. The seasonal and annual crop evapotranspiration under current climate (1991-2020) and future climate (2021-2050) were analysed using the mean annual temperature, mean annual precipitation, and mean monthly potential evapotranspiration for average of 30 years. The spatial distribution of crop evapotranspiration was calculated considering the evapotranspiration coefficients taken from literature using four stages of crops growth. Additionally, the absolute and relative changes of the annual crop evapotranspiration were carried out. The annual crop evapotranspiration varies in the actual period from 56 mm to 1297 mm, while in the future period the annual crop evapotranspiration varies from 59 mm to 1410 mm, which implies the impact of future climate warming on the crop evapotranspiration in the South East Europe. The heights values were identified in the South of Greece, in the southwestern sides of Romania, in the East sides of Bulgaria, Croatia and European Turkey. The maximum seasonal crop evapotranspiration were found in the mid-season, both for present and future. The minimum values of seasonal crop evapotranspiration were obtained in the cold season, when the mean air temperature and crop coefficients are lower. The absolute and relative changes indicate the high values in the South and southwestern sides of the South East Europe.
