WATER WORLD
60% of key S.Asian water basin not usable: study
by Staff Writers
Paris (AFP) Aug 29, 2016


Sixty percent of the groundwater in a river basin supporting more than 750 million people in Pakistan, India, Nepal and Bangladesh is not drinkable or usable for irrigation, researchers said Monday.

The biggest threat to groundwater in the Indo-Gangetic Basin, named after the Indus and Ganges rivers, is not depletion but contamination, they reported in the journal Nature Geoscience.

"The two main concerns are salinity and arsenic," the authors of the study wrote.

Up to a depth of 200 metres (650 feet), some 23 percent of the groundwater stored in the basin is too salty, and about 37 percent "is affected by arsenic at toxic concentrations," they said.

The Indo-Gangetic basin accounts for about a quarter of the global extraction of groundwater -- freshwater which is stored underground in crevices and spaces in soil or rock, fed by rivers and rainfall.

Fifteen-to-twenty million wells extract water from the basin every year amid growing concerns about depletion.

The new study -- based on local records of groundwater levels and quality from 2000 to 2012 -- found that the water table was in fact stable or rising across about 70 percent of the aquifer.

It was found to be falling in the other 30 percent, mainly near highly populated areas.

Groundwater can become salty through natural and manmade causes, including inefficient farmland irrigation and poor drainage.

Arsenic, too, is naturally present, but levels are exacerbated by use of fertilisers and mining.

Arsenic poisoning of drinking water is a major problem in the region.

Water shortage: The demise of the Maya civilization
Vienna, Austria (SPX) Aug 26, 2016
Something really drastic must have happened to the Ancient Maya at the end of the Classic Period in the 9th century. Within a short period of time, this advanced civilisation in Central America went from flourishing to collapsing - the population dwindling rapidly and monumental stone structures, like the ones built at Yucatan, were no longer being constructed. The reason for this demise r ... read more
