Depleting groundwater resource of Northern India

Groundwater Change in India (2002-08)

In a recent press release from University of California -Irvin, reported the evidence of depleting groundwater resource in Northern India. Using satellite data, UC Irvine and NASA hydrologists have found that groundwater beneath northern India has been receding by as much as 1 foot per year over the past decade – and they believe human consumption is almost entirely to blame.

Study results have been derived from data from twin satellites called GRACE (Gravity Recovery and Climate Experiment). These twin satellites launched in March 2002, are making detailed measurements of Earth’s gravity field which will lead to discoveries about gravity and Earth’s natural systems.

According to study results, more than 109 cubic kilometers (26 cubic miles) of groundwater disappeared from the region’s aquifers between 2002 and 2008 – double the capacity of India’s largest surface-water reservoir, the Upper Wainganga,
People are pumping northern India’s underground water, mostly to irrigate cropland, faster than natural processes can replenish it, says Jay Famiglietti and Isabella Velicogna, UCI Earth system scientists, and Matt Rodell of NASA’s Goddard Space Flight Center.
Groundwater depletion in northwest India is a known problem, but Rodell’s data suggest that the loss rate is around 20% higher than the Indian authorities have previously estimated.
“If measures are not soon taken to ensure sustainable groundwater usage, consequences for the 114 million residents of the region may include a collapse of agricultural output, severe shortages of potable water, conflict and suffering,” said Rodell.
