This "breadbasket" underpins much of U.S. society, but it also relies almost entirely on a complex network of diminishing groundwater resources. In a short and provocative article, for GSA Today, Susan Stover and Rex Buchanan ask a simple question: "How long can the High Plains aquifer last? " This is a crucial question -- one that should force people across multiple disciplines and across multiple political divides to unite. The authors note examples for hope with good management, but this may take extraordinary efforts in a presently highly divided country. The article should get people, from all walks of life, collectively talking on a major issue. ARTICLEThe High Plains Aquifer: Can We Make It Last?

In the UK, about one third of the water that comes out of our taps is sourced from groundwater.

Groundwater supplies low after dry winter

The south of the country is particularly dependent on this underground store of water, with Cambridge Water and Cholderton Water relying entirely on the water found in the chalk and sandstone rock formations of the south-east. After a dry winter, groundwater levels are lower than normal for the time of year, and scientists from the British Geological Survey are keeping a close eye on the situation. Although February produced an average dose of rainfall for the south of England, it wasn’t enough to make up for the deficit resulting from a dry spell stretching all the way back to last summer. Met Office data reveals that, in the six months up to January 2017, much of the country was parched, with less than 70% of average rainfall falling across southern regions.

*****'Parched' Chinese city plans to pump water from Lake Baikal via 1,000km pipeline

According to reports in the Chinese media, urban planners in Lanzhou, the capital of Gansu province, have drawn up proposals to pipe water into the chronically parched region from Russia’s Lake Baikal, the deepest freshwater lake on earth. Li Luoli, an academic who is one of the plan’s cheerleaders, claimed the mega-project - roughly the equivalent of pumping water from Lake Como to London - was both theoretically feasible and “certainly beneficial” to China. “Once the technical issues are resolved, diplomats should sit down and talk to each other about how each party would benefit from such international cooperation,” said Li, the vice president of the China Society of Economic Reform, a state-run think tank.

Indian traders boycott Coca-Cola for 'straining water resources' More than a million traders in India are boycotting fizzy drinks including Coca-Cola and Pepsi after claims from from two Indian trade associations that foreign firms are exploiting the country’s water resources.

Indian traders boycott Coca-Cola for 'straining water resources'

Traders in the south Indian state of Tamil Nadu, which has a population bigger than the UK, will replace big brands with locally produced soft drinks. “These foreign companies are using up scarce water resources of the state,” said K Mohan, secretary of the Vanigar Sangam, one of the associations supporting the boycott. Concerns about excessive water usage by companies such as Coca-Cola and PepsiCo were heightened after low rainfall during the last monsoon.

In January, Tamil Nadu’s interim chief minister O Panneerselvam declared the state “drought-hit” and asked the central government for funds to help farmers. Keeping an eye on groundwater levels — UK groundwater in February 2017. BGS scientists analyse groundwater levels across the UK each month.

Keeping an eye on groundwater levels — UK groundwater in February 2017

The variation in levels gives us insight into how much water is stored in aquifers, and can give advance warning of drought or flood. At the end of January 2017, groundwater levels were low across much of the UK, as shown in Figure 1. Groundwater levels usually rise during the winter months, but it was unusually dry over the preceding six months and the onset of groundwater recharge was significantly delayed across much of the UK. South and south-east England, where the public water supply is particularly dependent upon groundwater sources, were most affected. These low levels might have signified the onset of a groundwater drought, "the sustained and extensive occurrence of below average availability of groundwater".

In Age of Extreme Weather, Industrial Farming Threatens Us All. Extreme weather is damaging to crop production and threatens food safety worldwide, according to a new study published in Nature on Wednesday. And the most developed nations like the U.S., which rely heavily on industrial monocultures for food production, are particularly vulnerable. The study, which evaluated cereal production losses due to extreme weather in 177 countries from 1964-2007, found that "droughts and extreme heat significantly reduced national cereal production by 9–10%....Furthermore, the results highlight ~7% greater production damage from more recent droughts and 8–11% more damage in developed countries than in developing ones.

" "That was a surprise to us," Navin Ramankutty, an agricultural geographer at the University of British Columbia and co-author of the study, told Mother Jones on Wednesday. As Ramankutty explained to CBC News, Tapping the Freshwater Ocean Under the Sea. Statoil, an oil and gas company based in Norway, has looked at fresh water for oil extraction, but isn’t rushing to develop it. According to Ola Anders Skauby, a company representative, any techniques they leverage need to be proven and cost efficient.

“The use of fresh water has been considered at Statoil, but currently there are no significant activities using fresh water due to uncertain improved recovery potential and costs,” Skauby says. Unchartered Territory If offshore fresh water becomes a viable resource, either for drinking or for improved oil recovery, legal disputes over rights to access and extraction will likely become an issue. So far, the situation has been relatively simple: each of the aquifers found to date is tied to a single nation. How much water does it take to make your favourite Christmas meals?
