Haze woes lIkely to lInger, worsen #AsiaNewsNetwork

Haze woes likely to linger, worsen #AsiaNewsNetwork


(The Nation/ANN)-VISITING CHIANG MAI on Tuesday, Prime Minister Prayut Chan-o-cha issued an order to end the haze crisis in the North within seven days, alongside declaring it part of the national agenda.

However, environmental groups like Greenpeace are saying that such an unprecedented short-term directive would do little to resolve what has become a persistent crisis requiring serious long-term measures.

Greenpeace country director Tara Buakamsri said the haze was not simply an environmental matter, but rather demands multidisciplinary knowledge to bring under control.

“About four years ago, judging from the number of hotspots there are now, we had the same old problem,” he said. “It’s the same story and we still haven’t effectively undertaken anything to address it.”

Tara was referring to the 10,133 large, open fires that the Geo-Informatics and Space Technology Development Agency (GISDA) observed in the North between January and May 2016.

Unlike the smog that enveloped Bangkok early in the year, the haze crisis in the North stems largely from spontaneous dry-season forest fires and other fires deliberately set to clear farmland.

GISDA has found that the number of hotspots in nine northern provinces including Chiang Mai has been climbing since early March. From the dozens initially seen, the number soared in mid-March, surpassing last year’s record for the same period.

As of this past Monday, the agency recorded 6,069 hotspots, compared to 4,722 in the same period last year.

The statistics echo those of the Royal Forestry Department, which recorded at least 5,909 hotspots in the North on Monday. Of these, 641 were burning outside forestlands, 772 were on farms abutting forests, and 4,496 were within forests.

Chiang Mai, Mae Hong Son, Lampang, and Tak are worst off, accounting for 63 percent of the fires observed. Chiang Mai alone had 1,033.

Most observers believe the northern blazes are closely tied to the region’s traditional farming practices.

Haze Free Thailand, a project run by the Research University Network, has been studying the causes since last year, looking for possible solutions.

Most of the fires are set during the dry season and are the result of different land-use patterns, it has found.

Every January and into February, farmers set fires in their lowland fields to burn off scrub from the previous crop and prepare the soil for planting the next one.

Every February and into March, people who forage for mushrooms and other woodland edibles set fires within forests and clear undergrowth to set firebreaks, and sometimes trigger out-of-control forest fires.

Critical factors have now begun contributing to the haze problem, particularly clearing highland forests for mono-crop cultivation and rotational farming. Corn has become the most popular crop in the region as more farmers sign contracts with agro-giants.

Project researchers found that bans imposed on outdoor burning every March and April do not deter farmers from burning off the leftover stubble in their fields ahead of the rainy season.

During mid-March, Tara had also observed smoke pouring into the North from neighboring countries, again the product of cropland burning.

Based on GISDA’s MODIS satellite imagery from March 11 to 17, it had captured 728 hotspots in Laos, 446 in Myanmar and 103 in Cambodia.

During that same period, the level of PM2.5 – particulate matter 2.5 microns or less in diameter – topped the World Health Organisation safe standard (25 micrograms per cubic meter of air) across 80 percent of Thailand.

It was clear, Tara said, that transboundary pollution was significantly adding to Thailand’s woes.

The positive note to this year’s haze crisis, he said, is that more citizens are now aware of the health risks posed by the fine dust particles in the air, and their loud complaints have caught the government’s attention.

Tara pointed out that the problem has impacts beyond the health of humans and the environment, extending to the economy as well.

Environmentalists have also noticed more fires in forests this year than in community woods.

Tara blames this on soured relations between farmers and forestry officials, who are perceived to be heavy-handed following the military orders when farms are found to be overlapping on forests.

This conflict, he said, also needs to be doused.

As for the pollution crossing borders, Tara said Southeast Asian countries cannot place much hope in the Asean Agreement on Transboundary Haze Pollution because it’s had a scant practical effect, due to member-countries’ shared policy of not interfering in each other’s internal affairs.

Instead, he said, the solution could lie in other means. Singapore, for example, has a law against business operators elsewhere creating air pollution.

Other countries should consider similar legislation, Tara said.

“But that would require a strong government, one that dares face up to big business. And big business often has a heavy influence in politics today, so I’m not sure if we could enforce similar laws here,” he said.

Of the world’s 100 most polluted cities, 99 are in Asia

Of the world’s 100 most polluted cities, 99 are in Asia

The world’s filthiest air is in India, but weighted by population it’s worse in Bangladesh. China’s notoriously unbreathable air is improving, while Jakarta is in danger of out-smogging Beijing, data from air monitoring stations all over the world has revealed.

Of the 100 most polluted cities in the world in 2018, 99 were in Asia, according to a global report on annual air pollution levels by Beijing-based monitoring firm AirVisual and environmental group Greenpeace published on Thursday.

Half of the world’s 50 most polluted cities are in India, and 22 are in China, with Pakistani and Bangladeshi cities making up the rest. In the top 100 smoggiest cities, 33 are in India, and 57 are in China.

The world’s largest country, however, has seen improvements in air quality in 33 of its dirtiest cities, thanks to emissions regulations and extensive air quality monitoring. Another 24 Chinese cities saw smoggier skies in 2018.

Eleven Indian cities in the top 100 have welcomed cleaner skies this year, while air quality has become smoggier in eight of them, where a cocktail of bad air from traffic, industry, and agricultural and waste burning contributes to the haze.

However, 14 of India’s most polluted cities had no data for 2017.

Gurgaon, also known as Gurugram, a city southwest of India’s capital, New Delhi, has the world’s most polluted air, with the annual average level of PM2.5—small particles considered the most dangerous to human health—more than 13 times higher than the World Health Organisation’s (WHO) air quality guidelines of 10μg/m3.

Average concentrations of pollution in Chinese cities fell by 12 percent from 2017 to 2018.

Yan Boquillod, director of air quality monitoring at AirVisual, told Eco-Business that the report’s standout air quality performer was China’s capital.

“Beijing has seen a dramatic drop in air pollution in recent years, particularly in the winter months, largely as a result of factory closures,” he said.

Beijing has seen PM2.5 levels drop from ‘unhealthy’ to the ‘unhealthy for sensitive groups’ between 2017 and 2018.

Four years ago, an air quality reading of around 200 µg/m³ was accepted as “normal” in Beijing, noted Boquillod, who is based in Beijing. In 2018, pollution dropped to roughly a fifth of that level.

However, Beijing air is still almost six times over WHO’s guidelines, and in February this year saw PM2.5 levels climb to a five-year high, up 28 percent year on year.

Hold your breath, you’re in Jakarta

In Southeast Asia, Jakarta registered the most polluted air in the sub-region last year. The Indonesian capital saw air quality worsen by 53 percent in a year, one of the biggest drops in a report that covered 3,000 cites all over the world.

Jakarta’s 2018 pollution levels, four and half times over WHO’s a target, were just 12 percent lower than in Beijing’s. The city, which has more coal-fired power stations near it than any capital city in the world and notoriously bad road congestion, hosted the Asian Games in 2018, and athletes collapsed due to the smog.

Hanoi, in the industrial north of Vietnam, is Southeast Asia’s second most polluted city, while three out of the five most polluted places in Southeast Asia are in Thailand.

Yeb Sano, the executive director, Greenpeace Southeast Asia, said that burning fossil fuels—coal, oil, and gas—was the most common culprit of global air pollution, which results in an estimated seven million premature deaths and costs the world’s economy US$225 billion a year.

Sano pointed out that climate change was making air pollution worse, by changing atmospheric conditions and exacerbating forest fires.

“Local and national governments can help tackle the effects of air pollution by providing adequate monitoring and reporting infrastructure,” Sano noted.

“What we need to see is our leaders thinking seriously about our health and the climate by looking at a fair transition out of fossil fuels while telling us clearly the level of our air quality, so that steps can be taken to tackle this health and climate crisis,” he said.
