            "description": "The Gravity Recovery and Climate Experiment Follow-On (GRACE-FO) mission  is a joint Earth-science project launched in 2018 by NASA and the German Research Centre for Geosciences to continue the work of the earlier GRACE mission. It consists of two satellites flying about 137 mi (220 km) apart in the same orbit around Earth, constantly measuring tiny changes in the distance between them. These variations occur because changes in Earth’s gravity, caused by shifting masses such as melting ice sheets, groundwater depletion, and ocean circulation, slightly alter the satellites’ speeds and separation. By precisely tracking these changes, GRACE FO allows scientists to map how water moves across the planet, improving our understanding of climate change, sea-level rise, and global water resources.This visualization uses data from GRACE FO to create an index based on percentile dryness, categorizing the dregree of wetness or dryness within three domains: groundwater storage, root zone soil moisture, and surface moisture. It updates weekly, and extends back over a period of a year from the current week.This visualization is created for use within the Earth Information Center (EIC). || ",

After examining many environmental and climate factors, the team of hydrologists led by Matt Rodell of NASA's Goddard Space Flight Center, Greenbelt, Md. concluded that the loss is almost entirely due to human consumption.Groundwater comes from the natural percolation of precipitation and other surface waters down through Earth's soil and rock, accumulating in aquifers - cavities and layers of porous rock, gravel, sand, or clay. In some subterranean reservoirs, the water may be thousands to millions of years old; in others, water levels decline and rise again naturally each year. Groundwater levels do not respond to changes in weather as rapidly as lakes, streams, and rivers do. So when groundwater is pumped for irrigation or other uses, recharge to the original levels can take months or years. The animation shown here depicts the change in groundwater levels with respect to the 2003-2009 mean, as measured each month from January 2003 to June 2013. || ",

That has been the case over a broad stretch of the Middle East where observations by NASA's twin GRACE (Gravity Recovery And Climate Experiment) satellites show a sharp decline in underground freshwater reserves over the last decade. Following a drought in 2007, hundreds of new wells were drilled in the Tigris and Euphrates river basin to obtain water for drinking and agriculture. The basin occupies 339,688 square miles of the Middle East, covering parts of Iraq, Iran, Syria and Turkey. By late 2009, the region lost 73 million acre-feet of water—equal to 60 percent of the volume of the Dead Sea—due to pumping from underground reservoirs. NASA scientists say this extraction is happening at a much faster rate than rainfall is restoring the groundwater.

            "description": "During the past decade, groundwater beneath the northern Indian states of Punjab, Haryana, and Rajasthan has decreased by more than 88 million acre-feet. That's nearly eight times the amount held in Lake Mead, the largest reservoir in the United States. Now at risk of experiencing severe shortages of this vital resource are the 120 million inhabitants of those regions. Using NASA's twin GRACE (Gravity Recovery and Climate Experiment) satellites, scientists measured tiny shifts in the Earth's gravitational field to determine the rate of groundwater change in India. Areas in red had slightly less mass due to a net loss of groundwater and therefore exhibited a weaker gravitational pull on the orbiting satellites. Areas in blue had greater mass and a stronger gravitational pull due to a net gain. Watch the data visualization in the first video below to see how India's groundwater supply declined over the six-year period between 2002 and 2008. || ",

            "description": "One of the biggest changes to global agriculture is less about the food itself as it is about the water we use to grow it. In some areas, farmers are using freshwater resources - including groundwater - at an alarming rate. The GRACE satellites enable scientists to discover changes to underground aquifers by monitoring changes in the Earth's gravity. In northern India, farmers rely heavily on irrigation to grow crops, and the resulting massive aquifer depletion creates an uncertain future for the region.

            "description": "Scientists using data from NASA's Gravity Recovery and Climate Experiment (GRACE) have found that the groundwater beneath Northern India has been receding by as much as one foot per year over the past decade. After examining many environmental and climate factors, the team of hydrologists led by Matt Rodell of NASA's Goddard Space Flight Center, Greenbelt, Md. concluded that the loss is almost entirely due to human consumption.Groundwater comes from the natural percolation of precipitation and other surface waters down through Earth's soil and rock, accumulating in aquifers - cavities and layers of porous rock, gravel, sand, or clay. In some subterranean reservoirs, the water may be thousands to millions of years old; in others, water levels decline and rise again naturally each year. Groundwater levels do not respond to changes in weather as rapidly as lakes, streams, and rivers do. So when groundwater is pumped for irrigation or other uses, recharge to the original levels can take months or years. More than 109 cubic km (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, and triple that of Lake Mead, the largest manmade reservoir in the U.S. The animation shown here depicts the change in groundwater levels as measured each November between 2002 to 2008. || ",
