The effect of climate change on crop water requirements of URBC command were observed with assumption of no change in the regulations relating to agriculture and irrigation over the period of 15 year during 1998 to 2013 in the study area of command of Ukai right bank main canal, Gujarat. The variation of CWR was observed due to the increase in temperature and greenhouse gases, whereas the change in rainfall and thunderstorms were non predictable parameter. Global warming is badly influencing the temperature and precipitation, which will directly have impact on the root zone in soil media, moisture condition and required volume of ground water. Although crop water requirement estimation is prerequisite for planning, development and functioning of water resources projections, it seems that the practice of estimating CWR using current data only is no longer going to work and the planning should be done in light of implication of global as well as local climate change effects. This study reveal the clear difference over the period of 15 year duration the CWR for the same command area has been considerable amount of 142.59 Day Cusec. This means Average CWR per year was 9.50 Day Cusec due to climate change effect. This study will be useful for decision makers to evaluate the negative effects of climate change to crop water demand in URBC and better planning for water resources management.
