Volume of fresh groundwater abstracted by country in 2007 is expressed in million cubic meter. Information in the table is available from 1990 to 2015. Groundwater refers to water present in the earth's crust in a saturated or non-saturated soil, weathered mantel or consolidated rock formation. Groundwater supplies drinking water to at least half of the world's population, and accounts for more than 40% of the water used for irrigation. Over the past 50 years, groundwater abstraction has increased by more than 300%.For more information, visit the Environment Statistics Section website: https://unstats.un.org/unsd/environment/default.htm.
