Bringing Bt Brown's history to life for the young

Efforts by volunteers, educators help students appreciate historical site
Amelia Teng Straits Times 8 Jul 13;

ONCE upon a time, it was only heritage and nature buffs who visited. But in recent years, Bukit Brown cemetery has been attracting a younger crowd.

The historical site popped up on the public radar after plans to build a highway cutting through it were announced in 2011.

Since then, more than 20 secondary schools, junior colleges and polytechnics have organised trips for students, guided by tomb explorer Raymond Goh and other volunteers.

In March, 450 Raffles Girls' School students visited the cemetery. "We wanted them to experience Bukit Brown, rather than hear and read about it," said teacher Regina Lee, 46.

Student Angelia Lau, 16, who was there for the first time, said: "The number of enthusiasts in Singapore who would go out of their way to educate others about what they are passionate about heartens me."

Temasek Junior College took 54 young people to the cemetery in May. Vice-principal Samuell Ang said the tour was an opportunity for students to "see the connections between issues discussed in lessons and the on-going preservation efforts of Bukit Brown".

In language arts and humanities classes, students learn about the effects of urbanisation on the environment through literary texts. After the tour, they are encouraged to write poems about history and memories.

"The learning journey really taught me how to appreciate our culture and roots as I never knew there was so much significance behind every tombstone," said student Caleb Chia, 16.

The cemetery has also attracted people from outside Singapore. Last month, Mr Goh gave a tour to 30 students who were here for a three-week summer programme at the Future Cities Laboratory, which researches urban planning.

Among them was 30-year-old Tomas Janusas, an architecture and city planning graduate from the University of California, Berkeley, who is doing his master's in the same subject in September. "It is one of the most emotionally, spiritually and historically charged places in Singapore I have visited so far," he said.

Some students have chosen to "document" the cemetery through projects.

For instance, Mr Goh was one of the interviewees in an 18-minute documentary produced last year by three former Nanyang Technological University students from the Wee Kim Wee School of Communication and Information - Mr Pedro Shiu, Ms Janie Chee and Ms Siti Nurbaya Rameh.

Mr Goh, 49, a regional director of a health-care company, has been conducting tours at the cemetery for the public since 2007.

He said he is glad younger people are showing an interest in the site. "It is where they learn things in an authentic setting, things that history textbooks don't say."

Why PM2.5 matters when measuring air pollution

Grace Chua Straits Times 8 Jul 13;

EVEN after the dust from this year's great haze settles, a more insidious matter will remain: the issue of fine particles.

Whether in hazy periods or in normal times, one of the main culprits driving Singapore's air quality down is fine particulate matter less than 2.5 microns in size, or PM2.5 for short.

In a haze episode, the PM2.5 lingering in Singapore's air comes from burning plant matter; in non-haze periods, it is from diesel engines and industry. PM2.5, more than larger particles, can have long-term health effects.

When Prime Minister Lee Hsien Loong said last month that Sars is infectious but haze is not, and so Sars can kill while haze will not, he was right - mostly. These fine particles are not some virus passed from one person to the next, causing them to fall very ill.

But that does not mean they have no effect on your health. PM2.5 is fine enough to enter the bloodstream, and being exposed to PM2.5 increases the risk of death in general and from heart and lung illnesses - and for every 10-microgram increase in annual PM2.5 concentrations, the added risk of dying from overall causes, cardiopulmonary disease and lung cancer goes up 4 per cent, 6 per cent and 8 per cent respectively over a 16-year period.

Newer studies suggest that fine and very fine particles can also reach the brain. The cognitive performance in people exposed to such particles is lower than in those less exposed. The smaller particles may also increase the risk of neurodegenerative diseases like Alzheimer's and Parkinson's.

Worse, they can be a vehicle for other toxic substances, ferrying these into the bloodstream and across the protective blood- brain barrier into the brain.

But PM2.5 doesn't directly infect people like the Sars virus. Instead, your experience will vary depending on who you are and how long you were exposed.

Most studies and health advisories are based on annual PM2.5, a measure of long-term exposure; the World Health Organisation's short-term PM2.5 guidelines are based on studies of short-term PM10 exposure.

The most vulnerable include young children whose bodies are still developing; the elderly; pregnant women; and those with chronic heart and lung diseases.

Singapore should pay close attention to fine particulate matter - its air quality on this front could be much better. Since 2002, the annual PM2.5 has ranged from 16 to 23 micrograms per cubic metre - double its long-range targets. In non-haze years since 2005, the 24-hour PM2.5 has been 30 to 42 micrograms per cubic metre. In contrast, the annual level in Australia's Sydney is seven micrograms per cubic metre, and in Los Angeles, US, it is 14.8.

Some of these fine particles are emitted by vehicles or industry, others are formed by chemical reactions in the atmosphere.

To its credit, Singapore has tightened its vehicle emissions standards. By 2014, new diesel vehicles must meet the Euro V diesel standards, which will have particulate matter emissions standards of a maximum 0.005 g per km.

The National Environment Agency (NEA) has stepped up its booking of smoky vehicles, even installing video cameras in some of the vans to catch them in the act. And off-road diesel engines used in construction must also meet emissions standards.

Will this cost more? It depends. There are some 38,000 old diesel commercial vehicles on the roads, belching smoke. Any incentive scheme to switch to the new Euro standard would conflict directly with a different measure announced in this year's Budget, which allows commercial vehicle owners to extend their COEs for five years to manage rising costs.

But SMRT, for instance, upgraded some of its buses to Euro V five years ago, while SMRT and ComfortDelGro cab companies have also made the upgrade. So consumers may already have accepted these direct costs.

In any case, residents will have to decide what price they are willing to pay for cleaner air - if commercial vehicle owners use the best available technology, this will be a one-off cost for at least some years.

Should the country go further, imposing more stringent guidelines or publishing more data? It depends on what's practical and for whom. The World Health Organisation says that as each person's exposure and experience may vary, each country should do what it needs to achieve the lowest PM2.5 concentration it can.

Even the United States doesn't always meet its own standards. An American Heart Association review found that "at the end of 2008, 211 US counties (or portions of counties) were in non-attainment of the 2006 daily PM2.5 national ambient air quality standards". More stringent guidelines, then, would be useless if they were not achieved.

However, PM2.5 and its hazards could be better communicated. While the Pollutant Standards Index does include PM2.5 as a subset of PM10, or all particles smaller than 10 microns in size, the fraction of PM2.5 within PM10 may vary. Two PM10 readings may both be "100 micrograms per cubic metre" and produce the same PSI value. But one may be 90 per cent PM2.5, while the other 20 per cent PM2.5 - with very different health effects.

During the haze, NEA put out the 24-hour average PM2.5 readings in micrograms per cubic metre every hour. Last year, it began giving the 24-hour PM2.5 readings thrice a day. Previously, it gave just the annual average.

During the worst of the haze last month, there were calls for the PSI to be changed to include PM2.5, but the PSI can't be changed to do this in the middle of a crisis. It would be too confusing. Instead, the NEA added more information on PM 2.5, and issued its health advisories based on the more unhealthy of the 24-hour PM2.5 reading and PSI values.

In future, it should go further and either colour-code the PM2.5 reading, or convert it into an individual PSI value, using the same sort of charts used for other pollutants. In the long term, researchers are keen to work with the NEA to study in more detail how particulate matter is formed and dispersed in Singapore's tropical urban context, and where it goes.

The bottom line? PM2.5 matters - even after the haze is over.

NUS conducts study on permeable road surface

Monica Kotwani Channel NewsAsia 7 Jul 13;

SINGAPORE: Porous surfaces could be another means of controlling flash flooding in Singapore.

For instance, concrete slabs with hole in neighbourhood carparks is among the many methods adopted by urbanised countries like Singapore to mitigate flooding after heavy rains. The little grass patches in them absorb rainwater.

Channel NewsAsia understood the National University of Singapore has been studying the concept of permeable surfaces for minor roads and pavements in a bid to slow down the flow of water into drains after heavy rainfall.

When it rains, the water will be absorbed through a layer of porous concrete and flow through a layer of gravel to store water temporarily.

The gravel has about 30 to 40 per cent space in between to store water.

An overflow channel will drain water from the gravel layer during heavy storms or long periods of rain.

Below the gravel, a layer of geotextiles, or permeable fabrics, filters the water further into the ground.

Weep holes are present throughout the subsoil layer for water to seep through to the drains.

This whole process could result in holding up to a few hours of rainfall and take up to 24 hours to slowly seep into the ground.

However, an engineering expert said challenges could still exist.

Associate Professor Tan Soon Keat, deputy executive director at Nanyang Environment and Water Research Institution, elaborated: "Maintenance will be an issue. If water can go through, it also means debris will be trapped between the pebbles. This type of practice coupled with proper design of base layer, can be used in pedestrian walkways or perhaps pathways in parks, or pedestrian malls."

Prof Tan said such porous surfaces would be most feasible in areas that don't carry heavy loads such as trucks and cars.

The national water agency PUB recently imposed stricter flood prevention requirements on new developments.

From June this year, developers will need to implement on-site measures to slow down the flow of stormwater into public drains.

This rule will apply to new projects that are of size 0.2 hectares or more.

Green roof is one of such on-site measures designed to control stormwater runoff.

Made up of plants and green spaces, these popular features on top of commercial and residential developments serve two functions - treating water for it to be reused and slowing the release of water into drains after a heavy downpour.

Experts said it makes sense for developments to play their part.

Chong Kee Sen, vice president of The Institution of Engineers in Singapore, said: "In Singapore, what we experience is short duration, high intensity rainfall. We are designed for that situation that happens once in every 10 years. It would be relatively costly for us to have storm drainage for public drains to be sized to cater to such situations. In land scarce Singapore, this may not be a viable solution.

"What could be a good solution in this case, where each small little development plays their part in reducing the maximum rainfall into the drainage system, thereby preventing a flood situation and at the same time, reducing the cost in terms of construction of public drains."

A flood prevention idea ... using porous road surfaces
Monica Kotwani Today Online 8 Jul 13;

SINGAPORE — The National University of Singapore is studying the idea of using permeable surfaces for minor roads and pavements, which could help prevent floods by slowing down the flow of water into drains after heavy rainfall.

These surfaces would allow water to be absorbed into a layer of porous concrete and flow through a layer of gravel, to be stored temporarily.

About 30 to 40 per cent of the space in between the gravel is used to store the water, which will then flow through a layer of geotextiles, or permeable fabrics, before it exits through small openings into the drain.

The whole process could hold up to a few hours of rainfall.

However, an engineering expert said challenges still exist.

Indonesia: Sumatran Tigers Kill One, Trap Five Others in Aceh National Park

Nurdin Hasan Jakarta Globe 7 Jul 13;

Banda Aceh. Search and rescue crews began the long trek into the depths of the Gunung Leuser National Park on Saturday to rescue five men who spent the last three days trapped in a tree after Sumatran tigers killed and ate a sixth member of their party, police said.

A 30-member team entered the 7,927 square-kilometer national park on Saturday after villagers’ attempts to rescue the men were thwarted by the site of four Sumatran tigers near the base of the tree, Aceh Tamiang Police chief Adj. Sr. Comr. Dicky Sondani said on Sunday.

“It might need two or three days to walk on foot to the depths of Leuser jungle,” Dicky said. “If the tigers are still under the tree, we will have to shoot and anesthetize them so that we can rescue the five [men].”

The men, all residents of Simpang Kiri village in Aceh Tamiang district, entered the dense national forest in search of the agarwood — known locally as gaharu — a rare and extremely expensive type of heartwood used in the production of aromatic oils and incense. Resin-infused agarwood is the result of a mold that infects the alim tree (aquilaria malaccensis), an endangered tropical evergreen found in the jungles of Southeast Asia.

A kilogram of agarwood can fetch some Rp 5 million ($505), Dicky said, but the jungles of the Gunung Leuser National Park house dangerous tigers and elephants. The police recently had to rescue another group of men trapped in the park, he said.

“It’s worse this time because there are tigers waiting for the villagers,” Dicky said. “People keep entering the jungle to look for alim wood because it’s very expensive; up to Rp 5 million ($505) per kilogram. But, well, that’s the risk; there are many tigers and elephants in Gunung Leuser’s jungle.”

The men were attacked by tigers on Thursday after they caught and killed a tiger cub in a snare meant to catch a deer, police said. Nearby tigers drawn to the scene of the injured cub and pounced on the men, killing and eating 28-year-old David as the five others climbed a tree to safety.

The residents of Simpang Kiri village entered the national park after the men called for help on their cell phones. But as the villagers neared the tree, the site of four large tigers and David’s partially eaten remains kept the rescue party at bay.

They have remained in the tree for three days.

Tiger attacks have become increasingly common in Sumatra, where palm oil and pulp plantations have destroyed much of the rainforest, shrinking animal habitats and putting the endangered tigers in contact with local residents. More than a hundred Sumatran tigers are believed to roam the grounds of the Gunung Leuser National Park, according to reports.

Aceh Loggers Saved After Five-Day Standoff With Pack of Tigers
Nurdin Hasan Jakarta Globe 9 Jul 13;

Banda Aceh. Five men were rescued from a tree in the depths of Sumatra’s Gunung Leuser National Park on Monday, ending a five-day standoff with seven Sumatran tigers who had been circling the tree’s base, prepared to pounce.

Deliverance came when courageous tiger tamers shooed the carnivorous cats away.

The men, loggers from the village of Simpang Kiri in the Aceh Tamiang district, had occupied the tree since last Thursday.

A sixth member of the logging party identified as David, 28, failed to climb a tree. The tigers mauled and ate him.

The confrontation began when a snare set by the loggers to catch deer instead trapped a tiger cub, killing it.

The five remaining loggers took refuge in a tree and contacted relatives via cell phone; however, a rescue party sent from their village was deterred by the sight of four tigers waiting at the tree’s base. After requesting help from police, a 30-member team of police officers and Army soldiers was dispatched on Saturday.

“I just got a report several minutes ago from the team on location that [the five men] have been rescued after tiger tamers lured the tigers away, deeper into the jungle,” Aceh Tamiang Police chief Adj. Sr. Comr. Dicky Sondani told the Jakarta Globe on Monday afternoon, adding that the team and the five villagers were expected to arrive in Simpang Kiri on late Monday evening.

“The rescue team will also evacuate what’s left of the victim eaten by tigers, and hand the remains over to his family.”

Dicky said the rescue team had planned to use guns to anesthetize the tigers if they could not get the animals to leave, but decided against it, as they were afraid the protected animals would be injured or even killed.

There was also a worry that other tigers in the area could begin attacking villages in retaliation.

The team attempted to shoot firecrackers to scare the tigers away, but it drew the animals toward them instead, searching for the source of the sound.

After consulting with villagers, the team decided to hire the help of tiger tamers. By this time, the pack of tigers waiting at the tree’s base had grown from four to seven.

The tamers arrived on location on Monday and managed to induce the tigers away with “special chants,” Dicky said.

The police chief declined to offer any details of the chants used.

The men were in very weak condition, Dicky said, because they did not have anything to eat or drink for the past five days.

According to the tiger tamers, the tree in which the loggers sought refuge was located near a cave inhabited by a tiger pack.

“The area is in fact called Tiger Hill because it is inhabited by many of the protected animals,” Dicky said.

He blamed the six villagers for entering the protected area to search for a rare and extremely expensive type of heartwood referred to by locals as “alim wood.”

“Those alim wood hunters appeared to have entered a tiger’s den. It’s their own fault: entering a protected forest because they have been tempted with expensive alim wood.”

Dicky said police would not charge the five loggers.

He said the incident would hopefully serve as a lesson for other villagers planning to enter the forest.

“We’re calling on villagers not to enter the protected forests of the Gunung Lesuer National Park because it is very dangerous.”

19 bloggers honoured at annual awards

Young and old, they were feted for making an impact at the 6th S'pore Blog Awards
Poon Chian Hui Straits Times 7 Jul 13;


Mr Ivan Kwan’s post on what seemed to be an eviction notice to Pulau Ubin residents set the public abuzz. -- ST PHOTO: DESMOND LUI

When Mr Ivan Kwan conceived his now award-winning blog in 2008, it was out of a personal interest in nature and wildlife conservation.

The former research assistant never thought that his post in April on what seemed to be an eviction notice to Pulau Ubin residents would set the public abuzz.

It even got the Government to publicly apologise for the poorly- worded letter, which was really meant to inform 22 households that they had to pay rent to continue living on the island.

This helped Mr Kwan become one of 19 winners at the Singapore Blog Awards held yesterday at a River Valley Road venue.

"The post went viral, which was totally unexpected," said Mr Kwan, 31, who first learnt about the notice from a birdwatcher.

The Housing Board document had stated that the residents' homes were slated for "clearance", suggesting that they were to make way for an adventure park.

It also said that officers will determine the residents' "eligibility of resettlement benefits".

Puzzled, Mr Kwan posted pictures of the notice on his blog, The Lazy Lizard's Tales, along with a call to the authorities to clarify the issue. The possibility that the kampung houses were about to be lost drew strong public reactions.

"I was heartened to know that so many people treasure Pulau Ubin," said Mr Kwan, whose blog was judged the best among those dealing with environmental issues.

"Blogs have the ability to impact current affairs, because they have the power to reach hundreds, or even thousands of people."

The Singapore Blog Awards, which is in its sixth year, recognises people who devote their time and energy to setting up and running innovative and informative blogs.

Organised by Singapore Press Holdings' bilingual news and entertainment portal, omy.sg, it drew more than 1,500 blog registrations.

The winners included Ms Christina Gao's Travelgraphy for best photography blog and Ms Jasmine Koh for best lifestyle blog, Scissors Paper Stone. Ms Grace Tan's Working With Grace won best individual blog. The winners were chosen from a shortlist of 190 by a panel of judges and online votes.

One of the judges, blogger Walter Lim, said this year's contenders were of a higher quality, and were more diverse. Topics ranged from parenthood to poetry, said the corporate communications manager.

"There were also many nice personal stories," added Mr Lim, who hopes to see blogs on finance and health matters in the future.

"It is also fantastic to see older bloggers - it shows that the trend is quite mainstream, no longer confined to the younger generation."

The winner of the best food blog was Mr Tony Boey, 53, a full-time blogger who writes about where and what to eat in Johor Bahru.

"I wanted to have a bit of an adventure, to go to unfamiliar places," said the ex-civil servant, who set up Johor Kaki Food Guide in 2011. He drives to Malaysia almost every day, sampling food from street stalls to high-end restaurants.

So far, he has written about nearly 500 places. Among his top priorities now is to document as many retiring hawkers as he can.

Mr Boey said that being older than most local bloggers did not pose any barriers: "When I'm online, I actually forget my age."

Economic impact by haze may not be great: Ng Eng Hen

Woo Sian Boon Today Online 7 Jul 13;

SINGAPORE — While the Government has not yet “sat down” to discuss it, the haze “hasn’t had a great (economic) impact” as Singapore carried on with their lives, said Dr Ng Eng Hen, Chairman of the Haze Inter-ministerial task force, during an interview with the media on Friday.

In response to a question on whether the haze had significantly impacted Singapore’s economy, Dr Ng said that it has not been the Government’s priority to discover the economic impact of the haze as it was a “short” episode which occurred over two days and a weekend.

“I would say that the impact hasn’t been as large as compared to Sars, for example. Singaporeans basically got on with their lives, and I think we need to do that, not only for the economic impact, but because it shows our resilience,” he said.

The possibility that the haze might last for several weeks or more had led some economists to reportedly total up the possible damage to the Republic’s economy, as some suggested that any estimate of the haze’s cost should start at S$300 million a month.

Dr Ng reiterated on Friday the importance of going on normally — albeit with a slower pace — with daily lives to minimise impact on all levels, and not just on the economy.

He said: “If we continue as we are, I think we can minimise it and when I say economic impact, I don’t mean just dollars and cents. We talk about how our daily lives are affected — garbage collection, cleaning, our festivities that we like to attend, the social impact is actually very great as well.”

When asked if the Government will introduce new rulings for childcare centres or voluntary-welfare organisations to be fully air-conditioned, Dr Ng said that “it may not be sensible” to be “a completely air-conditioned nation”.

While he acknowledged that the haze has shaped Singapore’s behaviour, using an example of how the Ministry of Social and Family Development had rolled out a S$2.5 million fund to help childcare centres and kindergartens purchase air-conditioners or retrofit their centres, Dr Ng said that “major responses” should not be made.

Pointing out that the gap between this year’s major haze situation and the one which occurred in 1997, Dr Ng said: “(We are) dependent on wind and rain, we’ll just have to examine it ... We shouldn’t make major responses. Let’s study it.” WOO SIAN BOON

Better haze early warning system being “looked into”: Dr Ng
Better early warning system against haze lined up; agencies to sharpen contingency plans
Woo Sian Boon Today Online 7 Jul 13;

SINGAPORE — A better early warning system to predict if and when the haze will hit Singapore is currently being “looked into” by the Ministry of Environment and Water Resources (MEWR), with the Minister coordinating the country’s efforts pledging that government agencies will continue sharpening their contingency plans should the haze return.

Speaking to the media during an interview on Friday, Dr Ng Eng Hen, who is Chairman of the Haze Inter-Ministerial Committee, outlined several key lessons the authorities had gleaned from the haze episode — which hit hazardous levels two weeks ago — while stressing that the various ministries remain prepared to activate their plans if necessary.

While he pointed out that the National Environment Agency (NEA) had started issuing daily health advisories, and rolling 24-hr PSI readings as part of a “predictive system” to help Singaporeans better plan their activities during the haze period, Dr Ng said that “a better early warning system for haze” is needed as “we don’t really want to be caught by surprise”.

He said: “If we can have a better model ... At least we can tell Singaporeans, within a certain level of confidence that, ‘The hotspots are burning, the haze is headed this way, if the winds don’t change, it’ll hit us in ‘X’ number of hours, please be prepared’. It’s a simple statement that we can put out and it’ll be very useful.”

As such, MEWR and the NEA, with a team of health and weather experts, is currently looking into a system with a “more scientifically-based rigorous method”, which is based on the hotspots in Indonesia, weather patterns and historical data, to “better predict” if Singapore is “at risk of haze”.

When asked to elaborate when and how this early warning system will be rolled out, Dr Ng, who is also Defence Minister, did not indicate a timeline but revealed that better technology — such as satellite monitoring — is an advantage which can be leveraged on to do data “modelling”. Dr Ng, however, added that information from Indonesia on climate is necessary for a better predictive model.

He said: “We certainly want to ask them for better information on wind, rain so that we can predict better. The (ASEAN) agreement on transboundary haze actually operationalises that because there’s a clause that says more effective monitoring on hotspots as well as climatic conditions, so it’ll be very useful if that can be ratified.”

A better system is necessary as Dr Ng stressed that the haze is a “long-term problem” which can be expected to recur over the next few years. This is due to the scale of the area being set on fire as well as slashing and burning being the predominant method of forest-clearing in Indonesia.

Said Dr Ng: “Slashing and burning is the predominant method in Sumatra and other areas and has been practiced for decades, it isn’t a recent phenomenon ... I suspect that this practice will be hard to eradicate and change overnight.”

To “address the problem at its source”, Dr Ng said that a multi-pronged approach consisting of governmental diplomatic efforts, non-governmental organisations to encourage more sustainable practices on the ground and “avenues where consumers can help” is necessary.

When asked if Singapore is prepared if the haze returns and reaches hazardous levels, Dr Ng said he felt that Singaporeans are better prepared, while reiterating that the authorities’ main goal is to minimise disruption and ensure that life will go on as normally as possible.

In response to why there was a delay in the authorities’ announcement of their contingency plans, Dr Ng reiterated that the plans were in place but had to be customised to the specific “threat” Singapore might be dealing with.

He explained; “These contingency plans are generic in the sense that they respond to the haze, flu pandemic or terrorist threats ... But they have to be customised to the specific threat. It’s the haze now, couple of weeks hence, we might be hit by something else, and then we have to adapt.”

He also added that the haze crisis gave various agencies the opportunity to “validate their plans” and make sure that “they knew how to operationalise it”.

Dr Ng also said that the authorities’ responses and operation plans “have improved a lot over the years” from experience dealing with the Severe acute respiratory syndrome (SARS) or the H1N1 influenza infection.

He said: “We can never stop improving because if we’re slow, lives can be affected, but comparing across just this decade or so, I would say that our systems are much more structured in the way that we know which levels and things to activate.”

Singapore 'has learnt 5 key lessons from haze crisis'
Ng Eng Hen says the authorities will continue to monitor situation, fine-tune contingency plans
Feng Zengkun, Environment Correspondent Straits Times 7 Jul 13;

Singapore will be even better prepared for the haze if it returns with a vengeance, said Defence Minister Ng Eng Hen, pointing to five key lessons learnt from the latest episode.

At a press conference last Friday to assess the recent haze crisis, he added that the authorities will continue to monitor the situation and fine-tune contingency plans.

Dr Ng, who heads an inter-ministerial committee to tackle the haze problem, said: "I think we are better prepared, both our people and agencies. If the haze does return we are confident that Singaporeans will take it in our stride."

Last month, the annual haze in Singapore worsened to unprecedented levels, with the three-hourly Pollutant Standards Index (PSI) hitting a record 401 on June 21.

Air becomes hazardous when the index crosses 300.

Fires in Indonesia had led to the pollution here, before rain, fire-fighting efforts and winds gave Singapore a respite.

During a community event at Pasir Ris Elias Community Club yesterday, Deputy Prime Minister Teo Chee Hean also spoke about the recent crisis, saying episodes such as the haze were "a timely reminder of the importance of being prepared in different emergency situations".

Haze is a long-term issue

Dr Ng said the first thing Singaporeans need to realise is that the haze is a long-term problem.

Reports showed that both small farmers and large corporations in Indonesia are still burning forests to clear the land for crops.

"Our records on haze go as far back as the 1970s, and I suspect this slash-and-burn practice will be hard to eradicate and change overnight. This is an area where we need a multi-pronged approach," said Dr Ng, adding that Singapore must keep up diplomatic efforts with Indonesia.

Last week, Indonesia began preparations to ratify an Asean agreement on transboundary haze after meetings with Singapore and other Asean members.

The Republic also needs to enlist non-government groups to help spread environmentally friendly land-clearing practices in Indonesia, for example, mechanical methods such as using bull-dozers.

Better early warning system

At home, Dr Ng has called for a better early warning system for haze.

PSI readings, he pointed out, show what the air quality was like in the past hours or days, not what it would be in the near future. But a predictive model will help Singaporeans plan ahead.

The Government responded with health advisories for the next day, but he wants more to be done. He said the Environment Ministry is already looking at a better model to predict haze conditions. "I think it will help us all," Dr Ng said.

Information management is key

But how the information is presented to the public is also key.

While some preferred simple guidelines on how to react to the haze in the recent crisis, others expected detailed information.

"I agree that we can improve on this," said Dr Ng, explaining that the Government recognises the need to cater to different groups.

Asked why the relevant ministries' contingency plans were announced only almost a week after the haze hit record levels, given that the haze was a perennial problem, he stressed that the plans were in place but had to be "customised" for the specific crisis.

"These contingency plans are generic in the sense that they respond to say, the haze, flu pandemics, terrorist threats. Each time we have an emergency or crisis, they are updated."

The Singapore System is robust

Despite the challenges, Singapore was able to respond quicker this time, thanks to its experience in handling major events such as the severe acute respiratory syndrome (Sars) outbreak in 2003.

Dr Ng pointed out that the Government had distributed millions of face masks to homes and retailers within days. "Obviously there is room for improvement each time something happens, but we know our plans and structures are functioning as intended."

The authorities also rolled out other measures immediately, including subsidised medical treatment for haze-related conditions.

It also set up a fund to help childcare centres install air-conditioning to guard against the haze.

Singaporeans are resilient

But it was not just the Government which responded. Dr Ng lauded the initiatives taken by Singaporeans in helping one another fight the haze.

Not only did people get together to source and distribute masks, some even opened their air-conditioned homes so that others could take refuge from the haze, Dr Ng pointed out.

"That tells us the level of trust and care we have for one another," he said. "This is a good sign for nation-building. And I think if Singaporeans continue to respond this way it adds to our resilience."

Dr Ng said Singapore depended on Indonesia to solve the haze problem at its source.

"But if we take sensible precautions, look after ourselves and each other, the haze won't disrupt our lives. If the haze returns, I'm confident that Singaporeans will take it in (their) stride."

DR NG ENG HEN ON...

The health risks posed by the haze

We would like to tell Singaporeans, "You know what your health risks are when you are exposed to so many hours (of haze)"... But the data, unfortunately, is not that precise... Experts tell us that when conditions worsen, please stay indoors... that is the best they can do.

I think what people are doing - staying indoors, closing the doors, (using) fans, some using air purifiers - is the best that we can do on current evidence. Until somebody comes up with better studies to show that the risks actually are much more or much less, then we can calibrate it.

Why it took a while for the Government to announce its haze contingency plans

The plans were in place but we have to customise them to a specific threat. The fact that the haze went into unhealthy levels and we were able to activate masks, within a day or two, was a fairly quick response... This is in no way saying that we are satisfied with the response; we can always sharpen it... The fact that well over 80 per cent of Singaporeans polled said that Singapore would get through the haze, I think it's a measure of confidence in our system.

Whether Singapore can withstand a bigger crisis

I, personally, am gratified by the way Singaporeans have responded. There was a certain robustness in the systems, and more important than that, the way Singaporeans reached out to help one another.... it tells us the level of trust and care that we have for one another, which is essential in any crisis.

You can have the best-laid plans but if you don't have trust and care for one another, then you know it's each man for himself. So as long as we have that, I am confident that we can keep updating, keep strengthening...

Lessons learnt from recent haze episode
Saifulbahri Ismail Channel NewsAsia 7 Jul 13;

SINGAPORE: The Haze Inter-Ministerial Committee said the haze issue is a long term problem which Singapore and the region will have to face.

The Committee, which was activated when haze levels hit record highs in Singapore last month, believes the slash and burn method to clear forests in Indonesia is entrenched and hard to eradicate.

Recently, the Indonesian government has put in more efforts to reduce significantly the number of hotspots in the Riau province.

If the haze does return, the committee said it is confident that Singaporeans will take it in their stride as Singapore is better prepared as a result of lessons learnt during the recent haze episode.

After about two weeks of clear skies, the Haze Inter-Ministerial Committee headed by Defence Minister Ng Eng Hen shared lessons learnt from the recent haze episode.

Dr Ng said: "The first key lesson I feel we ought to learn despite all these developments which are positive in the recent weeks, is that the haze is a long term problem. Slash and burn is the predominant method in Sumatra and in other areas and have been practiced for decades. It isn't a recent phenomenon. Our records of haze go back as far back as 1970s and I suspect that this practice will be hard to eradicate and changed overnight."

Dr Ng believes a multi-prong approach is needed to deal with the problem.

This includes keeping up diplomatic efforts with the Indonesian government and getting help from non-governmental agencies to facilitate more sustainable practices.

In addition, a more robust early warning system will be useful to help Singaporeans prepare better for the haze and help them plan ahead.

Dr Ng said: "MEWR (Ministry of the Environment and Water Resources) is actually looking at the health experts and the weather experts, to come up with a better predictive model to look at the hotspots, weather patterns, historical data and correlate with actual haze conditions. I think all of us can recognise how difficult it is to predict weather. If we can have a better model, a model where we can trust or a more reliable model, I think it will help us all."

Singapore will continue to ask Indonesia for more information on wind and rain conditions to better predict the weather.

Another lesson learnt is about information management.

Information needs to be given out catering to different groups of people, and not to create fear or even panic.

The Committee is also determined not to let the haze overwhelm the nation.

Dr Ng said: "The key message then was that even if the haze worsens, turns hazardous, just slow down don't stop. Let's keep Singapore going. Don't allow the haze to overwhelm us. Let’s try to get on with our lives as much as possible because that's the way that we manifest our resilience and our ability to overcome."

When haze levels hit record highs, the immediate action taken was to restore confidence.

Masks were distributed to the poor and vulnerable.

"It was a good occasion for our contingency plans to be validated and I think we were able to respond much faster this time because of our experiences in the past decades - SARS, H5N1, and the Fukushima nuclear disaster. Each time that happened, we stepped up and just examined. The fact that the haze required us to activate plans gives us confidence that the so-called Singapore system works," said Dr Ng.

Even though the haze may have subsided for now, Dr Ng said government agencies will continue to sharpen its contingency plans and apply the lessons learnt. The Haze Inter-Ministerial Committee will also remain watchful during the dry season if the haze returns.

Thirty haze-related questions are expected to be fielded in Parliament during question time on July 8. They will cover legislation, health impact, contingency plans and safety of workers.

Indonesia: Police Name 24 Individuals, 1 Corporation Suspects Over Riau Fires

Ezra Sihite Jakarta Globe 6 Jul 13;

Twenty-four individuals and one corporation have been named suspects over their alleged roles in starting fires in Riau, Sumatra, that have ravaged forests and blanketed neighboring countries Singapore and Malaysia in hazardous haze.

“Until July 5, we have investigated numerous forest fire cases, and 24 individuals and one corporation have been named suspects,” Riau Police chief Brig.Gen.Condro Kirono reported to President Susilo Bambang Yudhoyono late on Friday during the launch of Yudhoyono’s official Facebook page and YouTube channel.

Condro said most suspects started the fires to clear land, adding that police have been questioning 14 witnesses from several firms suspected to be responsible for the blazes.

Conditions in Riau, he assured, are getting better following joint efforts by the police, the Indonesian Military (TNI), the Agency for the Assessment and Application of Technology (BPPT) and the National Disaster Mitigation Agency (BNPB) to put out the fires.

Meanwhile, Andri Hari, the Indonesian ambassador to Singapore, said that air quality in the city-state has been steadily improving.

“Since July 2, the PSI level has dropped to below 50, which is much better than a few weeks ago,” he reported to Yudhoyono via Google Hangout.

Andri said that Singaporeans were quite surprised that the Indonesian government managed to get the fires under control in such a short time.

Yudhoyono said the nation’s quick response to the catastrophe proved Indonesia’s commitment to putting out the fires.

“I don’t like hearing that Malaysia and Singapore think that we are not acting seriously in [handling the fires]. We are very serious about it, and we are continuing to monitor the situation,” he said.

PRECIOUS DISCOVERY: Timber concession area in Sarawak yields amazing find

Researchers from Sarawak Forestry Corporation collecting samples of the new species in Naha Jaley, Belaga recently

BELAGA: A NEW Rafflesia species was discovered in a timber concession area in Naha Jaley, Belaga recently.

Initial findings show its morphological characteristics resemble similar species, such as the Rafflesia keithii found in Sabah and the Rafflesia tuan-mudae found in Gunung Gading National Park.

"Its DNA does not show a complete match. It has overlaps between the two species. A detailed screening of the genome to determine its species is now being carried out, and it is possible that it may be new to science," said Sarawak Forestry Corporation managing director Datuk Ali Yusop yesterday.

Further research, funded by Pro-Natura Foundation Japan and headed by Sarawak Forestry environmental executive Bibian Diway, in collaboration with Japan Environmental Studies National Institute's Dr Yayoi Takeuchi and assisted by representative Abeng Awing from the local communities of Uma Balui, Naha Jaley and Belaga, will be carried out at the site.

Two more rafflesia sites along the banks of Sungai Bukoh and Sungai Keboho, both within the vicinity of Uma Balui, have also been discovered.

Though part of the Bakun Reservoir, these forested areas are also the hunting and farming grounds of local longhouse communities.

China hit by largest-ever algae bloom

(AFP) Google News 6 Jul 13;

BEIJING — The seas off China have been hit by their largest ever growth of algae, ocean officials said, with vast waves of green growth washing onto the shores of the Yellow Sea.

Pictures showed beachgoers swimming and playing in the green tide in the eastern city of Qingdao, while bulldozers shovelled up tonnes of algae from the sand.

The State Oceanic Administration said on its website that the algae, enteromorpha prolifera, started to appear a week ago and had spread across an area of 28,900 square kilometres (7,500 square miles).

The previous largest bloom was in 2008 when it affected around 13,000 square kilometres, it said.

Qingdao officials said they had removed around 7,335 tonnes of algae, the official Xinhua news agency reported.

The algal phenomenon is usually caused by an abundance of nutrients in the water, especially phosphorus, although the triggers for the enormous blooms which began to appear in the Yellow Sea in 2007 remain uncertain.

The China Daily quoted professor Bao Xianwen, of the Qingdao-based Ocean University of China, as saying: "It must have something to do with the change in the environment, but we are not scientifically sure about the reasons."

The algae are not toxic nor detrimental to water quality, but lead to extreme imbalances in marine ecosystems by consuming large quantities of oxygen and creating hydrogen sulphide.

Peak Water: Global threat to food supply as water wells dry up, warns top environment expert

Lester Brown says grain harvests are already shrinking as US, India and China come close to 'peak water'

Wells are drying up and underwater tables falling so fast in the Middle East and parts of India, China and the US that food supplies are seriously threatened, one of the world's leading resource analysts has warned.

In a major new essay Lester Brown, head of the Earth Policy Institute in Washington, claims that 18 countries, together containing half the world's people, are now overpumping their underground water tables to the point – known as "peak water" – where they are not replenishing and where harvests are getting smaller each year.

The situation is most serious in the Middle East. According to Brown: "Among the countries whose water supply has peaked and begun to decline are Saudi Arabia, Syria, Iraq and Yemen. By 2016 Saudi Arabia projects it will be importing some 15m tonnes of wheat, rice, corn and barley to feed its population of 30 million people. It is the first country to publicly project how aquifer depletion will shrink its grain harvest.

"The world is seeing the collision between population growth and water supply at the regional level. For the first time in history, grain production is dropping in a geographic region with nothing in sight to arrest the decline. Because of the failure of governments in the region to mesh population and water policies, each day now brings 10,000 more people to feed and less irrigation water with which to feed them."

Brown warns that Syria's grain production peaked in 2002 and since then has dropped 30%; Iraq has dropped its grain production 33% since 2004; and production in Iran dropped 10% between 2007 and 2012 as its irrigation wells started to go dry.

"Iran is already in deep trouble. It is feeling the effects of shrinking water supplies from overpumping. Yemen is fast becoming a hydrological basket case. Grain production has fallen there by half over the last 35 years. By 2015 irrigated fields will be a rarity and the country will be importing virtually all of its grain."
Running Low

There is also concern about falling water tables in China, India and the US, the world's three largest food-producing countries. "In India, 175 million people are being fed with grain produced by overpumping, in China 130 million. In the United States the irrigated area is shrinking in leading farm states with rapid population growth, such as California and Texas, as aquifers are depleted and irrigation water is diverted to cities."

Falling water tables are already adversely affecting harvest prospects in China, which rivals the US as the world's largest grain producer, says Brown. "The water table under the North China Plain, an area that produces more than half of the country's wheat and a third of its maize is falling fast. Overpumping has largely depleted the shallow aquifer, forcing well drillers to turn to the region's deep aquifer, which is not replenishable."

The situation in India may be even worse, given that well drillers are now using modified oil-drilling technology to reach water half a mile or more deep. "The harvest has been expanding rapidly in recent years, but only because of massive overpumping from the water table. The margin between food consumption and survival is precarious in India, whose population is growing by 18 million per year and where irrigation depends almost entirely on underground water. Farmers have drilled some 21m irrigation wells and are pumping vast amounts of underground water, and water tables are declining at an accelerating rate in Punjab, Haryana, Rajasthan, Gujarat and Tamil Nadu."

In the US, farmers are overpumping in the Western Great Plains, including in several leading grain-producing states such as Texas, Oklahoma, Kansas and Nebraska. Irrigated agriculture has thrived in these states, but the water is drawn from the Ogallala aquifer, a huge underground water body that stretches from Nebraska southwards to the Texas Panhandle. "It is, unfortunately, a fossil aquifer, one that does not recharge. Once it is depleted, the wells go dry and farmers either go back to dryland farming or abandon farming altogether, depending on local conditions," says Brown.

"In Texas, located on the shallow end of the aquifer, the irrigated area peaked in 1975 and has dropped 37% since then. In Oklahoma irrigation peaked in 1982 and has dropped by 25%. In Kansas the peak did not come until 2009, but during the three years since then it has dropped precipitously, falling nearly 30%. Nebraska saw its irrigated area peak in 2007. Since then its grain harvest has shrunk by 15%."

Brown warned that many other countries may be on the verge of declining harvests. "With less water for irrigation, Mexico may be on the verge of a downturn in its grain harvest. Pakistan may also have reached peak water. If so, peak grain may not be far behind."
