Yangtze drought triggers debate over China's Three Gorges dam
Prolonged drought along the Yangtze has reduced China's longest river to record lows, triggering a debate over the Three Gorges dam's ability to generate power, state media said Thursday.
The Yangtze last year fell to its lowest level since records began in 1877.
The Ministry of Water Resources Wang Shucheng said earlier this month that extreme and abnormal climatic phenomena like drought and floods have occurred more frequently due to global warming in recent years, Xinhua said.
More than 2.6 million people in southwest China's Sichuan province and Chongqing municipality, upstream from the dam, have been suffering from drinking water shortages since late February, according to the agency.

Shrinking Lake Chad symbolizes Africa's plight
For 40 years, people living along the shores of Lake Chad have watched helplessly as it vanished before their eyes.
Stark warnings, grand pledges of action and prayers have failed to make a difference -- Africa's fourth largest lake has been drying up like snow melting in the sun since the 1960s, experts say.
Lake Chad, which lies in hot and arid territory on the southern edge of the Sahara desert, shrunk from 25,000 square kilometres (9,650 square miles) in 1964 to less than 2,000 square kilometres in 1990 -- the sort of problem that will be in the spotlight on World Water Day on Thursday.
For Lake Chad, climate change and increased human use of its waters for fishing and agriculture are blamed for the fall in the water level of what is the world's third largest totally landlocked lake.
However, older residents of Bol, a town about 150 kilometres (90 miles) north of the capital N'Djamena, say the lake's rise and fall is a cyclical phenomenon which occurs every 40 years.
"Children of today don't believe us but, we, who have seen the two eras, are surprised," Youssouf Bodoum Bani, the head of Bol's highest traditional regional authority said.
"Grandparents say to us that it's a cyclical phenomenon, every 40 years. The last rise in water level dates from the 1960s, at that time everything was under water. And since, the water has vanished little by little.
"We are awaiting the next rise but I admit that today I am sceptical."
