Groundwater & Climate Change
Groundwater is the world’s largest accessible store of freshwater. It is the primary source of drinking water for half of the world’s population and supplies over one-third of the water used to irrigate land globally. As such, groundwater is critical not only to global freshwater security but also to global food security. Further, natural groundwater discharges sustain vital ecosystem services through the provision of baseflow to rivers, lakes and wetlands in many environments during periods of low or no rainfall. Growing demand for freshwater and increased variability in precipitation due to climate change both serve to intensify global dependence upon groundwater resources.
Despite the vital contributions of groundwater to human welfare and ecosystems, our understanding of the sustainability of current and projected groundwater demand, its impact on the earth system, and the impact of climate change on groundwater is limited. The IAH Commission on Groundwater and Climate Change (IAH-CGCC) and UNESCO-IHP GRAPHIC Programme are working together to improve our limited understanding of the relationships among groundwater, human development, and climate change. To achieve this goal, we have the following key objectives:
- to promote international and inter-disciplinary research among hydrogeologists, climate scientists as well as physical, social, and health scientists regarding the relationship between groundwater and climate change;
- to facilitate the dissemination of knowledge and exchanges of experiences related to groundwater and climate change through the organisation of conferences, lectures and meetings as well as the preparation of books, journal articles and popular articles; and
- to coordinate research activities and knowledge dissemination pertaining to groundwater and climate change with allied global initiatives.
