New NASA data show how the world is running out of water 21 of the world’s 37 largest aquifers have passed their sustainability tipping points, meaning more water was removed than replaced during the decade-long study period Underground aquifers supply 35 percent of the water used by humans worldwide Rain-starved California is currently tapping aquifers for 60 percent of its water use as its rivers and above-ground reservoirs dry up, a steep increase from the usual 40 percent. The aquifers under the most stress are in poor, densely populated regions, such as northwest India, Pakistan and North Africa.
