Four billion people face severe water scarcity, new research finds | Environment | The Guardian
▻http://www.theguardian.com/environment/2016/feb/12/four-billion-people-face-severe-water-scarcity-new-research-finds

At least two-thirds of the global population, over 4 billion people, live with severe water scarcity for at least one month every year, according to a major new analysis.

The revelation shows water shortages, one of the most dangerous challenges the world faces, is far worse previously than thought.

The new research also reveals that 500m people live in places where water consumption is double the amount replenished by rain for the entire year, leaving them extremely vulnerable as underground aquifers run down.

Many of those living with fragile water resources are in India and China, but other regions highlighted are the central and western US, Australia and even the city of London.

Ground water is depleting in the Colorado River Basin
By Stuart Winter
28 August 2014

A recent study of water loss in the Colorado River Basin since late 2004, published in Geophysical Research Letters, has determined that 75 percent of the loss came from underground sources. Seven western US states (Wyoming, Colorado, Utah, New Mexico, Nevada, Arizona and California) rely on the Colorado River and its tributaries for water for both individual use and agriculture. It is estimated that agriculture by itself currently uses approximately 60 percent of Colorado River ground water.

Rising sea levels threaten Los Angeles | Climate News Network

As much of California and the western US endures a severe drought, the city of Los Angeles is at increasing risk from rising sea levels, researchers say.

LONDON, 22 February – Los Angeles, City of the Angels in southern California, sits on a flat shelf of the Pacific coast of America, with a view of the sea. And if climate scientists are right, it could soon have an even closer view of the sea.

The city of more than 12 million people occupies 12,000 square kilometres of land, much of it no more than three metres above sea level. By 2050, rising sea levels could pose a threat to the infrastructure, museums and historic buildings of this great capital of entertainment, education, business, tourism and international trade, according to a new study by the University of Southern California.

Drought intensifies in western US | Climate News Network

▻http://www.climatenewsnetwork.net/2014/02/drought-intensifies-in-western-us

In recent days California has announced its most severe water restrictions ever as drought continues to hit the state. Scientists say the region’s rainfall has been declining over the years and the consequences are serious.

LONDON, 3 February – January is the month when Californians put on their rain jackets – but not this year.

It’s the month which is usually wettest in the western US, when rivers and reservoirs are replenished: this year there was virtually no rain through January in much of the region, following on from an exceptionally dry period through much of 2013.
