By the performed researches, the need to recalculate the elements of irrigation regime depending on the possible climatic changes, which could affect Romania, in the future, as well as the possibility of low limited water supply, in the context of the climate modifications.The global warming is a phenomenon unanimely accepted by the international scientific community, being already emphasized by the observation data analysis, during long periods. The simulations achieved by global climatic models underlined the fact that the main factors which determine this phenomenon are both natural (variations of sun light and vulcano activity) and anthropogeneous ones (changes in atmosphere compositiopn due to human activities).To achieve the proposed objectives, the paper presents three possible climatic scenarios, such as:1.Tn –  current average temperatures;  2.Tn+2 o C – increasing, with 2 o C, of the current average temperatures; 3.Tn+5 o C – increasing, with 5 o C, of the current average temperatures. The need to apply irrigation for a certain area was established depending on the moisture deficit calculated as difference between water consumption and supply sources for both soil and crops.The ETRO value was highly precisely estimated, using Thornthwaite method, and to follow all the modifications of the elements of irrigation regime, the water soil balances for all crops under study were achieved.The paper tries to underline the negative impact of global warming, as well as to find practical solutions for farmers to counteract the drought effects.Following the researches on world plane, measures to limit the alert rhythm of climate change were taken. The measures were discussed in international summits, as those of Kyoto and Copenhagen.To achieve the researches, indirect methods to determine the water consumption were used due to lack of modern equipments.The proposals are very important for irrigated farming, because it is important to produce a lots and cheap, for food security.The paper presents high level of originality, no similar papers were performed till present, in Romania.The modification of elements in irrigation regime could lead to devastating economical effects for Romania’s agriculture. Following increasing of average temperatures, there could be catastrophic effects, even as danger for human beings, under the current economical context.
