AB: Global change issues have gained widespread interests, but hydrologic studies of the effects have been largely limited to surface and very near-surface processes. Global climate change/variability and human activities may also have pronounced effects on groundwater systems, including groundwater storage and fluxes (recharge and discharge rates). A new initiative in collaboration with the UNESCO International Hydrological Programme (IHP) will address various subjects (groundwater fluxes, storage, and quality), methods (simulation, data analysis, remote sensing, and paleo-reconstruction), and regions of the world. The aim is to investigate a range of high-priority research areas, including: 1) spatial and temporal scaling issues; 2) quantitative plant physiology and succession for environmental stress responses; 3) hydrological boundary conditions, including sea-level and snow-pack changes; 4) coupled atmospheric-hydrologic-oceanographic processes and their feedbacks; and 5) feedbacks associated with societal adjustments in land/water resource management. In this presentation, we review published and ongoing investigations in these areas to identify knowledge gaps and potential for collaborative research under the umbrella of a proposed international project on Groundwater Resources Assessments under the Pressures of Humanity and Climate change (GRAPHiC).
