Singapore’s air quality unhealthy as Indonesia fires worsen

Singapore's air quality deteriorated to an unhealthy level on September 4 as forest fires in neighboring Indonesia continued to emit haze across South-East Asia. The city-state is currently one of the 10 most-polluted major cities worldwide, ranking third in IQAir's ranking. Minister for Sustainability and the Environment Grace Fu announced that the government had activated haze response plans for schools, workplaces, and community centers.

While most people could continue essential daily activities, the elderly and vulnerable were advised to check advisories before venturing outdoors. Singapore's Pollution Standards Index stood at 105, indicating unhealthy air quality. The fires and haze are a recurring issue often linked to traditional and commercial land-clearing practices.

However, this year's "super El Nino" weather pattern, expected to peak in September, threatens to exacerbate and prolong the adverse effects on public health and commercial activities across the region. The Indonesian part of Borneo saw an increase in fire hotspots, with authorities deploying 6,000 ground personnel and utilizing aerial water-bombing and weather modification to combat the flames.

Indonesia's biggest nickel complex may have to reduce its output by up to 40% due to drought affecting its water supply, while palm oil shipments are facing challenges due to drier waterways. Palm oil prices have increased by nearly 7% so far in the third quarter, nearing a two-year high. Other regions, such as Malaysia and Kalimantan, also faced deteriorating air quality, with Malaysia's Sarawak recording "hazardous" pollution levels.
