The human right to water entitles everyone to use sufficient, safe, acceptable, physically accessible and affordable water for personal and domestic uses. Clean water wherever found is essential to human survival: environmental degradation does not only render a scarce resource unusable; it also destroys natural ecosystems that support food production and biodiversity with repercussions for human health and eventually environmental security.
Groundwater has been estimated to provide almost half of all drinking water worldwide with approximately 2.5 billion people depending solely on this resource to satisfy their daily needs for water. Being the primary source of water available on earth today, the connection between a human right to water and the need to properly manage the scarce underground transboundary resources are significant. It is therefore vital to comprehend and account for groundwater dependence and the quantity and quality utilized.
