Groundwater levels are dropping across a much wider swath of the United States than is generally discussed, according to a new report, suggesting that the nation’s long-term pattern of groundwater use is broadly unsustainable.
Watch a video about the Columbia Water Center’s project to address a looming water crisis in north Gujarat, India.
As seductive as it is, depleting non-renewable aquifers to grow food is fundamentally unsustainable for the long term, as Saudi Arabia and other nations are finding out. According to a recent article by Lester Brown, in the 1970s the world’s largest oil producer realized it could use oil-drilling technology to tap deep underwater aquifers and—amazingly, [...]
A fascinating and frightening recent study from the National Resources Defense Council unveiled serious threats to water sustainability in the United States over the coming decades. In an era of rapidly unfolding climate change, the Council’s research found that more than 1,100 counties, or one third of all counties in the lower 48 states, face [...]
In part 1 of this interview, I talked with Columbia Water Center hydroclimatologist Stefan Sobolowski about the effects of continental snowcover on climate, and the implications of his research on climate change. In part 2, we talk about the problem of uncertainty in climate prediction models, extreme weather events, the regional variation of climate change effects and improved precipitation forecasting for India and the world.
Today, a growing number of scientists argue that global peak oil may be upon us—an argument that would seem to be supported by the increasingly heroic measures oil companies are taking (such as the ultra-deepwater drilling in the Gulf of Mexico) to keep up with global oil demand.
Many underground aquifers and even some surface water stored in lakes and glaciers can indeed be thought of as non-renewable—and thus subject to peak and decline–because they can be depleted faster than the natural recharge rate.
I recently came across an article in the Tehelka blog, which made me want to learn more. It was about a traditional water management system in the Uttarakhand region in northern India that has worked for years, but is being destroyed by funding meant to ‘modernize’ it.
The Economist has released a Special Report on Water, dated May 22nd, 2010, written by John Grimond. The 18 page report contains 9 short but substantial articles giving an overview of global water issues.
T Boone Pickens, well known for his strong opinions on renewable energy, is hoping that selling water to thirsty cities will be as commercially profitable as he’s found oil to be, and has been investing heavily in purchasing water rights. He opposes a public groundwater management plan that interferes with that.

The Guarani Aquifer in South America is a huge underground reservoir that lies under Paraguay, Uruguay, Argentina and Brazil, covering an area of land the size of Texas and California combined.
