N2 - The production and consumption of grain and energy need physical water resources which causes the virtual water circulation. The recycling of water requires energy, and the food production is associated with the consumption of biomass energy, which competes with the energy production for water. This paper uses the water footprint of food production and Water pressure index corrected to calculate Production and transfer of food and energy in Northeast China. The results show that the energy water footprint of the Northeast region was 4.3 × 108 m3 In 2000, it reached a maximum value of 4.39×108 m3 in 2012, and whereafter the energy water footprint fell to only 3.73×108 m3 in 2015. In Northeast China, more water is embedded in the outflow of food and in the inflow of energy. In 2000, the energy water footprint outflow was 1.54×108 m3, and the energy water footprint inflow in 2015 reached 1.89×108 m3. With the expansion of the food and energy production in Northeast China, water resources stress continues to rise. Except for Liaoning Province, the water resources pressure indices of Heilongjiang Province and Jilin Province are much higher than the national average.
