Root water uptake is described from the local scale, to the field scale and to the regional and global scales. The local macroscopic model can be incorporated in Soil-Plant-Atmosphere Continuum (SPAC) numerical models, like the SWAP, HYSWASOR, HYDRUS,ENVIRO-GRO and FUSSIM models. These SPAC models in turn can be used for upscaling, first to the field scale and from there to the regional and global scales. As Global Climate Models (GCMs) show a strong sensitivity to continental evaporation, closer rootwater-uptake modeling might improve soil vegetation control instead of uncontrolled continental evaporation
