Global groundwater map -Due to water shortage problems on local, regional and even global levels, the interest in groundwater has increased considerably during the past decades. In order to support the sustainable management of groundwater resources, it is necessary to map, model and quantify the stored volume and average annual replenishment of groundwater, while determining its chemical quality. The World-wide Hydrogeological Mapping and Assessment Programme (WHYMAP (link is external)) was created in 1999 in order to contribute to worldwide efforts towards better managing the Earth’s water resources, particularly groundwater. It is a joint programme of the United Nations Educational, Scientific and Cultural Organization (UNESCO), the Commission for the Geological Map of the World (CGMW (link is external)), the International Association of Hydrogeologists (IAH (link is external)), the International Atomic Energy Agency (IAEA (link is external)) and the German Federal Institute for Geosciences and Natural Resources (BGR (link is external)).
