Abstract

Climate Change is one of the most important environmental challenges that has a significant impact on fundamental resources, including water resources and so it is necessary to assess this phenomenon and predict its impact on the environment, environmental resources, agriculture and water resources. In this study, climatic parameters were simulated for six different climates of Iran using the general ocean circulation model GFDL-CM3 under two commonly used scenarios RCP4. 5 and RCP8. 5 and in two time periods of 2021-2040 and 2041-2060. Then results were used to predict the Water Footprint of agricultural crops for its two components; Blue Water and Green Water footprints. For this aim, 31 stations from all over Iran were selected and classified into six climate classes using the UNESCO classification and their 30-year meteorological statistics data were given as the input to the LARS-WG model. With the production of 200 series of data, meteorological data were generated over the desired time periods. The results showed that during future periods the temperature in the study areas will increase from 0. 5 ° C to 2. 03 ° C and rainfall changes will increase from-16 mm to 100. 2 mm. This will cause changes in green and Blue Water footprints in different climates of Iran from-13. 44% to 37. 53% in Green Water footprint and-18. 77% to 38. 20% in Blue Water footprint. Among the studied climates, the SA-K-W and PH-C-W climates will have the largest reduction in Green Water footprint and the highest increase in Blue Water footprint, and will be most affected by Climate Change and its consequences.
