     abstract = "{This study examines the impact of anthropogenic water regulation (AWR)
        on hydroclimatic systems by incorporating an AWR module into the
        Community Integrated Earth System Model (CIESM), validated
        against GRACE satellite data. This approach assesses the
        influence of human activities, including irrigation and
        groundwater extraction, on global and regional hydrology and
        climate. Key findings include: Implementation of the AWR module
        significantly improves terrestrial water storage (TWS)
        simulation accuracy in CIESM. The correlation coefficient for
        global-scale TWS improved from 0.33 in the control (CTRL) to
        0.89 in the experiment (EXP). Notably, the model's performance
        enhanced in Northern India and the North China Plain, while the
        Central United States showed limited improvement. AWR markedly
        alters the global water cycle, evidenced by substantial
        increases in soil moisture (about 0.04 to 0.02 m3/m3) and
        evapotranspiration. These changes have led to increased latent
        heat flux (around 5 W/m<SUP loc=``post''>2</SUP>) and a decrease
        in temperature by 0.1 {\textdegree}C to 1 {\textdegree}C in
        heavily irrigated regions. The study highlights the role of AWR
        in modifying the energy balance, particularly in agricultural
        areas where irrigation exerts a significant cooling effect.
        Despite its potential, the study identifies considerable
        uncertainties in coupling AWR within the CIESM model, related to
        inherent model limitations, incomplete water intake data,
        variable groundwater levels, and simplifications in water
        transfer parameters. Future research should aim to refine these
        aspects, focusing on enhancing the physical mechanisms and
        performance of AWR modules in hydroclimatic simulations. In
        conclusion, this research underscores the substantial
        modifications in hydrological and climatic conditions due to
        human activities. The improved AWR scheme within CIESM provides
        valuable insights for understanding and predicting climate
        change impacts on water resources, demonstrating its utility in
        simulating complex hydroclimatic changes at both global and
        regional scales.}",
