GLOBAL CLIMATE OBSERVING SYSTEM
ESSENTIAL CLIMATE VARIABLE - Groundwater
DomainTerrestrialDescriptionIt is estimated that groundwater accounts for around 30% of the world’s total freshwater resources, including those locked in snow and ice, and is by far the largest available reservoir of liquid freshwater. It is today the source of about one third of global water withdrawals. Estimates of the number of people who depend on groundwater supplies for drinking range from 1.5 to 3 billion. Global groundwater abstraction has at least tripled over the past 50 years, much more so in some regions. [GCOS-195 6.3.3]
