The Guardian: Photographs of a smog-wreathed Tiananmen Square and the iconic headquarters of China Central Television dominated reports of Chinese pollution last year, but analysis shows nine other Chinese cities suffered more days of severe smog than the capital in 2013.
The worst was Xingtai, a city of more than 7 million people south-west of Beijing, which was hit by 129 days of “unhealthy air” or worse – the threshold at which pollution is considered at emergency levels – and more than twice as many days as the capital experienced.
Beijing suffered 60 days of pollution above emergency levels, sparking reports of an “airpocalypse”, a boom in sales of air purifiers and masksand measures to tackle the problem including the destruction of open-air barbecues and a crackdown on fireworks for Chinese new year.
Last week, the Chinese premier, Li Keqiang, “declared war” on pollution, saying it was “nature’s red-light warning against the model of inefficient and blind development.”
The new analysis by Energy Desk, a site published by Greenpeace, is based on Chinese government data of fine particulates (PM2.5s), that have been linked by studies to increases in lung cancer and heart failure. It ranked cities against the US air quality index, based on how many experienced “very unhealthy” days or worse, roughly equivalent to levels the Chinese government considers an emergency.
Fang Lifeng, Greenpeace east Asia climate and energy campaigner, said: “China’s air pollution crisis usually makes the headlines when the smog cloud hits Beijing, but this research shows just how widespread this problem really is. There are now millions of Chinese people living in cities with air pollution above emergency levels for a third of the year, while other urban areas have gone a whole 12-month period with hardly any days of good-quality air.”
Beijing only had 13 days considered “good” on the US index last year, with 70 days of moderate air pollution, 64 at unhealthy for sensitive groups, 148 unhealthy days, 45 very unhealthy, 14 deemed hazardous and one day that registered at “beyond index”, ie off the scale. Weather conditions in Beijing and the surrounding regions often compound the particulates generated by coal burning, cars and industry, with cold winter air trapping the pollution.
China is not the only country suffering air pollution problems, and far from the worst. Iran is home to four of the world’s most polluted cities, with Quetta and Peshawar in Pakistan also in the top 10 alongside Kanpur and Ludhiana in India, data from the World Health Organisation shows.
Started in year 2010, ‘Climate Himalaya’ initiative has been working on Mountains and Climate linked issues in the Himalayan region of South Asia. In the last five years this knowledge sharing portal has become one of the important references for the governments, research institutions, civil society groups and international agencies, those have work and interest in the Himalayas. The Climate Himalaya team innovates on knowledge sharing, capacity building and climatic adaptation aspects in its focus countries like Bhutan, India, Nepal and Pakistan. Climate Himalaya’s thematic areas of work are mountain ecosystem, water, forest and livelihood. Read>>
