Haze hits Singapore as hot spots in Sumatra increase

Singapore’s air quality fell into the unhealthy range yesterday, official readings showed, as increased forest fires from neighbouring Indonesia brought haze to the city-state. At 2pm, the 24-hour Pollutant Standards Index readings in the eastern and central part of Singapore was above 100, levels at which people are advised to reduce prolonged strenuous outdoor activities. Transborder haze is a perennial problem in Southeast Asia as regulatory loopholes make it hard for authorities to eliminate Indonesia’s slash-and-burn land clearing practices. Singapore’s National Environment Agency said 212 hot spots were detected on Indonesia’s nearby Sumatra island on Friday, up from 65 on Thursday and 15 the day before.
A brief shift in the wind direction on Friday afternoon blew some of the lighter haze toward Singapore, worsening the island nation’s in air quality, it said. The traditional land clearing methods are used almost every year to clear land in Indonesia for palm oil and pulp and paper plantations that public records show are owned both by domestic and foreign or overseas-listed companies.
Indonesia was dousing forest fires with water sprayed from helicopters and inducing rain through cloud-seeding, the environment minister said on Friday, denying that hazardous haze was crossing borders.
Earlier in the week Malaysia urged Indonesia to take action on the fires within Indonesia’s borders as the air quality in Malaysia hit unhealthy levels. Indonesia’s president Joko Widodo told reporters yesterday extreme dry weather was causing wildfires in many areas, but the situation was much better than in 2015 when 2.6mn hectares (642,4739 acres) of land got burned, according to an estimate from the World Bank. He urged the authorities and the local government to immediately put out any fires before they spread.
In 2015 and 2019, such fires burned millions of hectares of land in Indonesia and sent haze billowing across several southeast Asian countries, generating record emissions, scientists have said. The most severe haze conditions recorded in Singapore were in September 2015, when the 24-hour index exceeded 300 to the hazardous level, prompting school closures.
Transboundary haze
The perennial issue of transboundary haze has again sparked friction in Southeast Asia, with Malaysia’s environment minister writing to the Indonesian government this week calling for a regional response to the toxic smoke drifting across his nation. The letter comes just weeks after countries in Southeast Asia committed to a haze-free region by 2030.
What’s going on?
In recent weeks air quality in parts of Malaysia and Indonesia has spiked into the red, with indexes consistently showing readings above 150 - putting it in a bracket where people can experience health effects, and those with sensitive conditions could suffer more serious problems.
On the Indonesian side of Borneo island visibility was reduced to less than 10m, while schools have been shut in both Indonesia and Malaysia to minimise the health impact on young children. Malaysia has blamed the haze on Indonesia, saying that smoke from forest fires drifts over the border. Every few years, during the dry season, smoke from “slash and burn” land clearing, largely to make way for oil palm, pulp and paper plantations, engulfs much of the region, posing a threat to public health, education and businesses such as tourism.
How is the problem being addressed?
Despite pleas by Malaysia this week not to “normalise” the haze, Indonesia has flatly denied any responsibility. Indonesia’s environment minister Siti Nurbaya Bakar said on Friday that forest fires had declined and no haze was detected moving toward any neighbouring country. Indonesia has been addressing the fires by water bombing via helicopters, she said. Indonesia has in the past taken legal action against companies suspected of illegal burning, but each year fires continue with varying degrees of severity. In 2015 and 2019 Indonesia was struck by catastrophic blazes that burned millions of hectares of land, causing record-breaking emissions and engulfing some places in toxic yellow smoke.
Why does this keep
happening?
Under Indonesia law burning by small-scale local farmers is permitted provided it occurs on a maximum area of two hectares and necessary prevention measures are in place.
All large-scale planters are obligated to comply with sustainable palm oil standards, which prohibit burning. The regulations mean that slash and burn techniques continue to be used by small-holder farmers who rely on the cheap land clearance method and for whom compliance to the standards is voluntary.
Opaque supply chains, overlapping land claims and these regulatory loopholes mean that large companies, which are in some cases owned by firms based in countries such as Malaysia and Singapore, can sometimes avoid responsibility for illegal land clearance.
How is the region
responding?
The Association of Southeast Asian Nations (Asean) recently launched a co-ordinating centre for Transboundary Haze Pollution Control (ACC THPC). Intended to help members prevent, mitigate and monitor transboundary haze, the centre is in line with Asean’s commitment to achieve a haze-free region by 2030. This week Asean agriculture and forestry ministers also agreed to take collective action to minimise and eventually eliminate crop burning.
Is climate change making it worse?
Indonesia is home to the world’s third largest rainforest area and the government needs to take more action, environmentalists say. The country is experiencing exacerbated dry conditions due to the El Nino weather pattern this year. Greenpeace Indonesia says climate warming is increasing the intensity and frequency of forest and land fires, which are in turn fuelling the climate crisis.
Why palm oil?
Global consumption of palm oil, used in a wide range of products such as cookies, candles and as a cooking oil, is growing rapidly. Palm oil is the world’s most used edible oil, accounting for 60% of global vegetable oil exports. For Indonesia, the world’s biggest palm oil producer, the product is one of the biggest export earners after coal. Export earnings from palm oil and its derivatives stood at $39.28bn in 2022, according to Indonesian Palm Oil Association.
