Pumping Groundwater Raises Sea Level

Posted on May 24, 2012. Filed under: Science | Tags: , , |

For many crops around the world, farmers must supplement rainfall with irrigation — and much of this added water comes from underground reservoirs. Globally, extraction rates now greatly exceed that of groundwater recharge, and have begun raising sea levels.

Pumping groundwater, some 70 percent of it to irrigate crops, has recently become a potent force in global sea-level rise, two new studies conclude.
It sounds obvious: Once brought to the surface, water will eventually run into the seas, says hydrologist Yoshihide Wada of Utrecht University in the Netherlands.But until now, most major assessments of factors affecting sea-level rise — such as those reported by the Intergovernmental Panel on Climate Change — ignored the role of groundwater extraction, he says. For instance, the IPCC has assumed that groundwater extraction would be largely balanced by river water impounded by dams.
Such an assumption was probably accurate until about 1980, says Yadu Pokhrel of Rutgers University in Piscataway, N.J. Since then, the balance has shifted, he says, and groundwater extraction is now developing into a growing force behind sea-level rise.
In recent years, sea level has been rising around 3.1 millimeters each year. Besidesgroundwater depletion, other major contributors include themelting of glaciers and polar ice fields, and the expansion of ocean water as it heats up.By 2003, groundwater removal was responsible for about 34 percent of that sea-level rise, Pokhrel and his colleagues report online May 20 in Nature Geoscience. They added all human water-use components to a computer program that projects climate impacts, assuming that any water demands not met by surface water came from groundwatersources.
Wada’s team also found groundwater pumping to be a bigger contributor than thought. By 2000, these researchers report online May 8 in Geophysical Research Letters , global groundwater depletion was causing sea levels to rise some 0.57 millimeters each year — around 18 percent of current annual sea-level increases and an amount of water roughly equivalent to twice as much as dams were holding back. This analysis, unlike Pokhrel’s, used globally recorded data on groundwater extraction.
This imbalance stands to onlygrow, Wada notes. His team adapted computer programs to, for the first time, project how humans’ water use wouldaffect sea level through 2050. By then, the scientists calculate, reservoir impoundment would prevent about 0.1 millimeters rise in sea level, while groundwater depletion would increase sea level by more than eight times that amount.
The new studies confirm groundwater extraction as animportant and growing factor in sea-level rise, says Leonard Konikow of the U.S. Geological Survey in Reston, Va. But he challenges the magnitude reported by the new studies. His own analysis, published last September in Geophysical Research Letters , pegged groundwater extraction’s impacts at only 13 percent of the recent increase.
“Many people think that groundwater pumping effects will be small or localized,” Pokhrel says. But the new data, he says, show that cumulatively, these withdrawals are changing sealevel globally.

Mobile Vs TV: Mobile is Winning?

Posted on May 24, 2012. Filed under: Mobile, Technology | Tags: , , , |

Mobile and Tablets seems to be winning as the prime entertainer and information source as far as youth is concerned, says a recent TCS Survey.

Days after The Mobile Indian reported about the increase in IPL viewership via mobile phones, a recent survey has now said that the young generation prefers Facebook and mobiles for entertainment over the traditional television.
The TCS GenY survey 2011-12, which quizzed 12,300 high school students across 12 cities in India, said that television is the least favourite mode of entertainment for the young generation with less than one per cent of respondents voting for it. On the other hand, 28 per cent opted mobile phones as their preferred mode of entertainment.
The survey said that in Mumbai 98.77 per cent of high school students own mobiles, and 59 per cent of them access the Internet through their phones.
Tablet penetration, too, is higher in the metros with 15 per cent listing it as the device of choice for Internet access, while it stands at 7 per cent in mini-metros.
The TCS Survey also said that increasingly India’s urban Gen Next is turning to text and chat as alternatives to voice. Also, 50 per cent of those surveyed in metros said that they used SMS the most to communicate while 45 per cent used IM (Instant Messenger) and 38 per cent used Facebook or Twitter – all significantly higher than the number of students in metros who said they used email (34 per cent) for the same purpose.
Social networks like Facebook is the clear favorite among students to connect with their peers with 88 per cent of respondents from the six metros having a presence on this social platform. One-third of all respondents said that it was their preferred site. Other platforms like Orkut and India-based networks like Apnacircle, iBibo and Hi5 are more popular in mini-metros compared to metros.
Tweeting as a medium of communication is now being used by one in three students in the TCS survey, though only 1 per cent listed it as their preferred site.

No More Updates for Symbian: Nokia

Posted on May 24, 2012. Filed under: Mobile, Technology | Tags: , , , , , , , |

Symbian Belle is the last ever version of Symbian as Nokia has reportedly shelved plans to bring the Carla and Donna upgrades for the operating system.

There will not be any more updates for the Symbian operating system after the Belle upgrade, Nokia has reportedly said.
The Finnish handset manufacturer had assured support from its Symbian operating system after it inked a deal with Microsoft to bring devices with the Windows platform of the later. Analysts then termed the deal as the death knell for the Symbian but Nokia has several times in the past promised support for the operating system.
However, now an Italian Nokia fan site, Nokialino reported that the Finnish handset maker has shelved its plan to bring the Carla and Donna upgrades for its Symbian operating system. Nokialino has quoted Mathias Fiorin, theproduct marketing manager of Nokia for South Europe, as saying this.
Thus, Symbian Belle which was announced back in March this year for Symbian based smartphones will be the last and the final build of the operating system being made available to the users globally. After this there will be no name change for the operating system so no more Symbian Carla or Donna in the pipeline.
Nokia will be issuing feature packs as it was done just about a couple of weeks before for the devices with faster processors to unlock newer functionalities. Following this there will be another feature pack that will be launched in place of a new operating system and that should pretty much seal the fate for Symbian operating system.
As far as new functionalities are concerned we notice that the Symbian Belle feature pack1 brought along just a handfulof them and similar thing is being expected by the upcoming feature pack 2 also, if any.
But there is still hope as Nokia is yet to announce the sad demise of the operating system officially.
