Chinese workers dig deep to keep crops watered after drought hits largest lake

With China’s biggest freshwater lake reaching historic low levels thanks to drought, work crews are digging trenches to keep water flowing to irrigate crops.

The dramatic decline of water coverage in Poyang Lake in the central province of Jiangxi would
have otherwise cut off irrigation channels to neighbouring farmlands in one of China’s key rice-growing regions.

Crews using diggers to create trenches only work after dark due to the daytime heat, the official Xinhua News Agency reported.

High temperatures have sparked mountain fires that have forced the evacuation of 1,500 people in south-west China, and factories have cut production as hydroelectric plants reduce their output amid drought conditions.

The drought and heat have wilted crops and shrunk rivers including the giant Yangtze, disrupting cargo traffic and reducing power output.

Fed by China’s major rivers, Poyang Lake averages around 1,400 square miles at high season, but has contracted to just 285 square miles amid the recent drought.

A wide area of western and central China has seen days of temperatures exceeding 40C in summer heat waves that have started earlier and lasted longer than usual.

In the hard-hit city of Chongqing, department stores have delayed their opening to 4pm. Residents
have been seeking respite from the heat in air raid shelters dating from the Second World War.

That reflects the situation in Europe and elsewhere in the Northern Hemisphere, with high temperatures taking a toll on public health, food production and the environment in general.
