Singapore’s air quality worsens to ‘unhealthy’ levels amid Indonesia’s denial of causing haze

Singapore ’s 24-hour PSI air pollution reading in the east of the island rose as high as 117, with a reading between 101 and 200 deemed ‘unhealthy’

Seven Indonesian provinces have declared a state of emergency for land and forest fires, but the country denies haze from Indonesia had spread to other countries

Singapore said air quality in the centre and east of the island has reached “unhealthy” levels and warned that hazy conditions may be widespread due to forest fires in Indonesia, increasing tension in the region over cross-border air pollution that causes respiratory illness and can slash tourism revenue.

Singapore’s 24-hour PSI air pollution reading in the east of the island rose as high as 117, according to the National Environment Agency website on Saturday. An index reading between 101 and 200 is deemed “unhealthy”, while a level above 300 is categorised as “hazardous”.

Indonesia said seven provinces have declared a state of emergency for land and forest fires, but denied that haze from Indonesia had spread to other countries.

“Up until this morning, we have not detected any transboundary haze,” Laksmi Dewanti, director general of climate change control at the Ministry of Environment and Forestry, said at a press briefing. Satellite imagery on Saturday showed more than 7,700 hotspots – seven times the number recorded a year ago, she said.

A week ago, Malaysia complained that smoke from fires in Indonesia’s southern Sumatra and Kalimantan had reached Malaysia, shrouding some areas of the country and causing air quality to drop. Indonesia denies that it was the source of the pollution.

The choking smoke from fires is a recurring problem in Southeast Asia, disrupting tourism and, at its worst, causing severe respiratory illness and costing local economies billions of dollars. It mostly originates from natural or man-made fires in Indonesia and Malaysia during the dry season. Many of the blazes result from illegal burning to clear farmland for cash crops such as palm oil, a practice that persists despite years of government efforts to stamp it out.

Malaysia blames Indonesia for haze sparked by cross-border fires, prompting rebuff from Jakarta

Indonesia’s foreign ministry said earlier that Malaysia sent a letter to the environment and forestry ministry, describing the latest air quality situation and offering to cooperate on dealing with the forest fires if needed.
