Central China drought worst in over 50 years: reports
May 25, 2011 by Dan Martin
A Chinese farmer walks through his dried up field in Huangpi, central China's Hubei province on May 9, 2011. The drought plaguing central China for months has left more than one million people without proper drinking water and crimped output of hydroelectric power, China's second-biggest energy source.
Central China's worst drought in more than 50 years is drying reservoirs, stalling rice planting, and threatens crippling power shortages as hydroelectric output slows, state media said Wednesday.
Rainfall levels from January to April in the drainage basin of the Yangtze, China's longest and most economically important river, have been 40 percent lower than average levels of the past 50 years, the China Daily said.
The national flood and drought control authority has ordered the Three Gorges Dam, the world's largest hydroelectric project, to increase its discharge of water by 10 to 20 percent for the next two weeks.
The measure is aimed at sending badly needed water to the Yangtze's middle and lower reaches for drinking and irrigation.
Water-marks in more than 1,300 reservoirs in Hubei province, where the dam is located, have dropped below allowable discharge levels for irrigation, the paper quoted Yuan Junguang, Hubei's reservoir management director, as saying.
Rainfall in some areas is as much as 80 percent lower than usual while the provinces of Anhui, Jiangsu, Hubei, Hunan, Jiangxi and Zhejiang along with Shanghai municipality are mired in their worst droughts since 1954.
"Without adequate water, we lost the spring planting season for rice," Hubei farmer Zhou Xingtao was quoted as saying.
It said many other farmers in Hubei have lost their existing crops or given up on planting summer rice, fearing the emergency water supplies will be inadequate to sustain their fields, with more hot and dry weather forecast.
The agricultural impact is likely to further alarm officials already trying to tame high prices of key items such as food.
Chinese farmers prepare to pump water from a drying up reservoir at a well in eastern China, where a record drought threatens to push global food prices up. Rainfall levels from January to April in the drainage basin of the Yangtze, China's longest and most economically important river, have been 40 percent lower than average levels of the past 50 years, the China Daily said.
China -- and the Yangtze river region in particular -- is prone to the alternating threats of crippling drought followed by devastating flooding.Just last summer, sustained torrential rainfall across the region caused widespread flooding and even some concern over whether the giant Three Gorges Dam would be able to contain the deluge.
More than 3,000 people were reported killed in the flooding and related landslides.
Nearly every year, some part of China suffers its worst drought in decades, and meteorological officials have said previously the extreme weather may be due to climate change.
The State Grid, China's state-owned power distributor, reportedly said this week that 10 of its provincial-level power grids were suffering severe shortages due to the drought's impact on hydroelectric generation, including Shanghai and the heavily populated southwestern Chongqing region.
China could face a summer electricity shortage of 30 gigawatts -- the most severe power shortfall since 2004, the company said.
The drought also is posing a threat to the Yangtze basin's highly-endangered population of freshwater dolphins, as water levels have plunged as much as three metres (10 feet) in key dolphin areas, raising the risk of stranding the animals.
Chinese farmers dig a new well at their farm in Huangpi, central China's Hubei province on May 9, 2011. Nearly every year, some part of China suffers its worst drought in decades, and meteorological officials have said previously the extreme weather may be due to climate change.
There are an estimated 1,000 of the dolphins -- fewer than the giant panda -- and that number is falling due to pollution and other environmental woes.China last week said the Three Gorges Dam has caused a host of ills that must be "urgently" addressed, in a rare admission of problems in a project it has long praised as a world wonder.
The State Council, or cabinet, acknowledged problems with water pollution, relocation of area residents, and seismological risks from the huge reservoir behind it.

We're swamped with rain here and the Mississippi River is out of its banks!
I hope that these weather extremes will encourage scientists to "get real" about the Sun's influence on Earth's changing climate.

It rains, it's global warming/climate change, it stops raining, it's hot, it's cold. "[Scientists] have said it may be due to climate change."
A few years ago a well meaning knucklehead kid from Greenpeace approached me outside a DC subway train station telling me how climate change is depriving Atlanta of water with their reservoir running low at the time (as an excuse to ask for money, of course). "Are you saying that it will not rain again in Georgia?" I rhetorically questioned back.
China gets droughts and we get floods. $#It happens. Anyone ever heard of the dust bowl? Go read the first chapter or two from Steinbeck's "Grapes of Wrath". The world really needs some perspective on things. We have better recorded history in history and yet perspective is so lacking. I suppose the multi-year drought in Oklahoma and Kansas back then was man-made too, but then how did it get fixed?

Yes, Earth's climate is controlled by a variable star - the Sun [1].
The Sun, life itself, and the cosmos are powered by dynamic competition between the attractive force of gravity and the repulsive force between neutrons [2].
World leaders, Al Gore, the UN's IPCC and an army of government-paid climatologist ignored these experimental facts [1,2] and generated "scientific-evidence" of CO2-induced global warming.
Fortunately President Eisenhower warned us that government science might one day become corrupt in his 1961 farewell address to the nation [3].

My understanding is that historically, Texas has only (half of - it is on a border) one semi-natural lake (the result of an earthquake and a man-made log jam, if the stories are true). All the rest are man-made. Texas is covered in lakes. Whether intended for the overall environment (doubtful), or just for local usage, building all those lakes turned out to be one of the best things for Texas' environment that man could probably do. My knee-jerk reaction to stories about droughts (regardless of political slant, and even in the absence of one) is "build more lakes".
Easier said than done, obviously, but still I think it is a good idea. Just avoid things like the "Three Gorges" debacle if possible, OK?
