Beijing’s water crisis and economic collapse

(July 15, 2009) Beijing consumes more water than is deposited there by rainfall and snow and has been forced into major water mining projects. In the past, around 50 years ago, the city had numerous aquifers that could be tapped by relatively shallow wells of 2 to 3 meters. Now wells of 50 metres are required to access that water. Indeed of Beijing’s consumption of almost 4 billion cubic metres of water per annum, most still comes from the disappearing aquifers. The fear is that this source of water is rapidly drying up and that has the potential to plunge the capital into major water resource crisis.

Peak water? The limits of a resource

(May 29, 2009) Wise management and sustainable development of the world’s water resources is a task that has been postponed too long.  Much of the world is in crisis and parts of the United States are rapidly approaching that point. Water-poor regions can no longer expect to put off addressing the problem by pumping ever greater amounts of relict groundwater from shrinking aquifers. Geoscientists should play a leading role in designing innovative solutions such as aquifer storage and recovery (ASR) where seasonally-surplus water supplies are banked in porous underground formations for later use.

Drought plagues China’s crops

(March 1, 2009) Northern China is dry at the best of times. But a long rainless stretch has underscored the urgency of water problems in a region that grows three-fifths of China’s crops and houses more than two-fifths of its people – but gets only one fifth as much rain as the rest of the country.
