Signs of record drought along China’s longest river

A month-long heatwave and record low rainfall have resulted in an unprecedented drought along the Yangtze, China's longest river.

Lakes and tributaries have receded as a result of the drought, exposing riverbeds and even a 600-year-old Buddhist stone carving and rocks below the famous Guanyin Pavilion, in Wuhan, Hubei province.

Low river levels have reduced the ability of hydro-electric power stations in the area to generate energy.

Emergency measures imposed to save electricity include factories closing, shops reducing opening hours and office buildings switching off air conditioning - all in response to the double-whammy of high demand for electricity and low production.

In big cities sited along the river, Shanghai is switching off its famous waterfront lights and the city of Luzhou is turning off street lights at night, in an attempt to ease pressure on the power grid.

Summer rainfall in the Yangtze river basin is the lowest since records began in 1961, according to China's Ministry of Water Resources.

Similarly, sustained regional heatwaves have also broken all established records, according to China's National Climate Centre.

Temperatures peaked last week, with the National Meteorological Centre issuing its highest 'high temperature alert' for six consecutive days between 12-17 August.

Forest fires have broken out in the Sichuan province, with the Chongqing municipality being particularly badly affected.

The low water level has also affected drinking water supplies in local communities, forcing the authorities to release water from the Three Gorges and Danjiangkou reservoirs to alleviate shortages, state broadcaster CCTV reports.

Across the region, the drought poses a threat to China's autumn crops, with thousands of acres' worth already lost in Sichuan province.
