East Azerbaijan province is one of the important provinces in crop production, with the production of 7.28% of the country's wheat and 4.76% of barley, which has an important role in providing these two products. But in recent years, because of Multiple droughts, Decreased rainfall, and irregular distribution of that, The dire condition of running water in the basin of Urmia lake, Decreasing groundwater levels and increasing their salinity, etc., agricultural production, especially the production of these two products, is facing the challenge of water shortage, which has made the water consumption management to be of particular importance, especially in the agricultural sector. Accordingly, in this study, using one of the water management tools, namely water footprint, the components of the water footprint of wheat and barley have been investigated in 21 counties between 2007-2017. Based on the results, the average water footprint of irrigated wheat and barley in the second half of the study period are 2928 and 2888 m3/ton, and in Rainfed wheat and barley are 2998 and 2829 m3/ton, respectively. The average water productivity in both wheat and barley crops is 0.34, which shows that the cultivation of both crops has the same pressure on the province's water resources. In the most county of the province, the share of blue water footprint was more than green water footprint and In general, the share of blue, green, gray, and white water footprints for irrigated wheat is 33.5%, 20.6%, 12.6%, and 33.3% and In the irrigated barley, it is 34, 20.7, 15.5 and 29.8 percent, respectively. Also, for both rainfed wheat and barley, the share of green and gray water footprints is 88.3 and 11.7 percent.
