Unsustainable Groundwater Management

“Public perception of freshwater is often dominated by visions of rivers and lakes. Groundwater is rarely a part of that imagination. Historically, it has been a hidden resource, and it remains so even now. The irony is that aquifers contain over 98% of Earth’s liquid freshwater.

Global and national water data are not very reliable. It is estimated that on a global basis, groundwater provides 36% of potable water, 24% of industrial water supply and 42% of water for irrigation. These estimates vary. In some countries, agriculture consumes the lion’s share of groundwater. Withdrawals from the Arabian aquifer system, for example, account for 84% of the region’s freshwater resources, most of which is used for farming. Human dependence on groundwater and the associated challenges varies considerably from one place to another, even within countries. Groundwater levels in some of the most densely populated river basins, such as the Indus and the Ganges-Brahmaputra basins in South Asia, have been plummeting. Groundwater’s invisibility and the lack of political interest are two key reasons that exploited aquifers are neither easy nor quick to remedy.”
