Xinjiang warns of more floods, risk to crops amid heatwaves

SHANGHAI • China's Xinjiang region yesterday warned of more flash floods and mudslides, and risks to agriculture as heatwaves swept across the region, accelerating the pace of glacial melt and posing hazards for its cotton production.

China has been baked by above-normal summer heat since last month, with some meteorologists blaming climate change. The excessively hot weather has driven up demand for electricity to cool homes, offices and factories. In agricultural regions, drought has been a concern.

Xinjiang's latest heatwaves have been particularly long-lasting and widespread, Dr Chen Chunyan, chief expert at the Xinjiang Meteorological Observatory, told state media. She said the extreme weather in the south and east of the region, more than twice the size of France, has already lasted for about 10 days.

Xinjiang's meteorological bureau renewed its red alert for the region - the highest in a three-tier heat warning system - yesterday, forecasting temperatures in Kashgar, Hotan, Aksu and Bazhou could exceed 40 deg C over the next 24 hours.

"Continued high temperature has accelerated glacial melting in mountainous areas, and caused natural disasters such as flash floods, mudslides, and landslides in many places," Dr Chen said.

The China Meteorological Administration said a day earlier that the glacial melting in Xinjiang poses a high risk of dam failure on a tributary of the Aksu River near China's border with Kyrgyzstan.

Mostly known for its deserts, Xinjiang is also home to long mountain ranges along its borders, including the Tian Shan mountains, the Pamirs, the Kunlun mountains and the Karakoram, which have become increasingly popular for Chinese tourists amid Covid-19 restrictions on international travel.

Temperatures in the oasis city of Turpan hit 45.8 deg C at 5pm.

Such heatwaves could also impact crops, especially cotton, Dr Chen said. Xinjiang accounts for production of about 20 per cent of the world's cotton, a water-thirsty crop.

The latest round of extreme temperatures has affected some 20 provinces. As of 5pm, 84 red alerts were in force across China, mostly in Xinjiang and the manufacturing provinces of Zhejiang and Fujian.

Temperatures in the city of Taizhou, in Zhejiang, hit an all-time high of 43 deg C yesterday.

"The hot and sunny weather is expected to continue tomorrow (Sunday) and the day after," state media quoted Taizhou's meteorological bureau as saying.

Chinese experts have called for more investment and adaptive measures to mitigate the health risks caused by climate change.

Professor Huang Cunrui from Tsinghua University's Vanke School of Public Health said adaptation and mitigation are necessary to protect people's health from climate-related risks. However, current funding for adapting to climate change in the health sector accounts for very little among climate finance projects, he said.

"Net benefits from well-protected health such as a reduction in hospitalisations, morbidity and premature deaths, can outweigh the economic costs of mitigation measures," he said.
