Comparison of total blue water use (TBWU) between statistics and corresponding values in this study. (a) Scatter plots of simulated average TBWU and corresponding statistical BWU for 31 provinces from 1991–2019. (b) Comparison of TBWU simulated by this study, Chiarelli et al.22, Mialyk et al.23, and Wang et al.25 with statistical data for 31 provinces in 2016. Box plots of RMSE (c), NRMSE (d), MAE (e), and R2 (f) for rice, wheat, and maize from 2005–2013 at the city scale compared with Zhou et al.19.
