Climate change and global water resources

This paper assesses the implications of climate change for global hydrological regimes and water resources, suggesting increased water stress for billions by 2025.

The research method involved using climate change scenarios from Hadley Centre climate simulations to assess changes in global hydrological regimes. A macro-scale hydrological model simulated river flows at a spatial resolution of 0.5×0.5 degrees, and changes in national water resources were calculated and compared with national water use estimates.

The research examines the potential impact of climate change on global water resources, using climate scenarios from Hadley Centre simulations and a macro-scale hydrological model. It predicts changes in river flows, national water resources, and water stress for populations, considering both supply and demand pressures. The study indicates that climate change could exacerbate water stress in some regions while ameliorating it in others, with significant regional differences between scenarios. It highlights the sensitivity of impact estimates to climate and socio-economic scenarios and discusses the limitations of the analysis scale and impact indices definitions.
