Drought in the USA & other world regions (Rev #2)

This is a collection of references on drought in the USA & world-wide water crises.

14 years into a devastating drought, it is on the verge of losing it all.

“The situation is as bad as you can imagine,” said Tim Barnett, a climate scientist at the Scripps Institution of Oceanography. “It’s just going to be screwed. And relatively quickly. Unless it can find a way to get more water from somewhere Las Vegas is out of business. Yet they’re still building, which is stupid.”

The crisis stems from the Las Vegas’s complete reliance on Lake Mead, America’s largest reservoir, which was created by the Hoover Dam in 1936 - after which it took six years to fill completely. “But over the last decade, as Las Vegas’s population has grown by 400,000 to two million, Lake Mead has slowly been drained of four trillion gallons of water and is now well under half full. Mr Barnett predicts it may be a “dead pool” that provides no water by about 2036.

Water shortage: middle east, asia, africa source: world-bank

However, another recent item in the news provides more evidence for the water crisis. Note this applies primarily to the Middle East, Africa, and Asia:

Salient quote: “Water shortages could strip off 14% of GDP in the Middle East and nearly 12% of GDP in the Sahel – without a radical shift in management, according to the bank’s projections.

Central Asia could lose close to 11% of GDP and east Asia about 7% under business-as-usual water management policies, according to a new report.“

Incredibly, nearly 2/3 of water is already being lost in some of these cities simply because of poor water infrastructure and leaky pipes. The added GDP losses are projected based upon climate change.
