South-east Asia is battling the worst haze in a decade as wildfires in Indonesia have raised health concerns and outrage across the region, where droughts and floods are being worsened by a very strong warming cycle across the Pacific Ocean.
Millions of people across Indonesia, Singapore, Malaysia and the Philippines are suffering hazardous air from the fires, which are centred on the islands of Borneo and Sumatra and have destroyed more than 200,000 hectares, according to the latest available official data.
This year’s fires have been exacerbated by a strong El Niño, a cyclical weather pattern which intensifies both dry conditions and heavy rainfall.
