#Bangkok in danger of flooding unless old drainage improved, say academics.


BANGKOK will not be safe from the severe impact of major storms unless there is a huge improvement in the capital’s drainage system and canal network, academics have warned as more heavy rain is predicted for the capital.


A group of academics on water management, disaster prevention and city planning said at a public seminar at Chulalongkorn University yesterday that Bangkok’s drainage system was old, poorly maintained and unable to drain the water adequately, which increases the risk of Bangkok being severely flooded if another storm hits.

Thailand Global Warming Academy director Thanawat Charupongsakul said that Bangkok lacked the preparedness to cope with a storm. The widespread flooding in 55 areas of the city last Saturday showed that Bangkok could not withstand even a portion of the deluge and it took a day to drain the floodwater.

“It is not frequent for Bangkok to be directly hit by tropical storm, but the city is situated on the storm route and was hit directly several times in the past, such as in 1952 and 1983,” Thanawat said.

.
He said that the precipitation within a six-hour period on Saturday night exceeded 214 millimetres and broke a 10-year record. 

If the rain was measured per hour, it was only 40 millimetres, which was within Bangkok’s drainage capacity, but it still flooded and showed the inability of the system to handle the volume, he said.

He warned that Bangkok will suffer badly from flooding if a storm hits the city directly with up to 300 millimetres of rain per hour.
“Bangkok’s sewage system is already more than 30 years old. It is suffering from a lack of maintenance, land sinking problems, and garbage and sediment clogging, which greatly reduce the drainage capacity,” Thanawat said.

“Moreover, the construction of a floodwall along the Chao Phraya River also increases the water level in the river higher than the water level in the drainage system and canals, which makes the water drainage to the river hard and slow,” he said.

He also pointed out that the lack of separation between sewage from households and rainwater drainage also hinders drainage, because more than 10 million citizens in Bangkok release around 6 million cubic metres of wastewater into the system every day.

Terdkiat Sakkhamduang , the former chairman of Thai Urban Designers Association, suggested that Bangkok’s drainage system has to be entirely improved and the city plan also has to be revised.

Water pumps ready

“We have learned a lesson from the flaws in Bangkok’s city plan that prioritise too much in replacing canals with expanding the road network. We should learn from our past and restore the canals, as the canal network can drain water far better than the sewage system,” Terdkiat said.

Bangkok governor Pol General Aswin Kwanmuang warned yesterday that Bangkok would face more heavy rains overnight, which may be as severe as the downpour last Saturday. He said Bangkok Metropolitan Administration (BMA) had prepared for the downpour by getting the water pumps ready and lowering the water level in the canals.

  Interior Minister General Anupong Paochinda also affirmed that Bangkok residents should not be worried over the potential danger of flooding from northern run-offs, as the Royal Irrigation Department was in control of water in dams and 12 water-retention fields in upstream areas could absorb floodwater before it reached the capital. 

Chai Nat’s Chao Phraya Dam was currently receiving about 2,500 cubic metres of water per second, which was in balance with the level it released, he said.

Myanmar’s AIDS-related deaths decline 52% in 6 years


A new global report says that Myanmar’s AIDS-related deaths have declined by 52 percent in six years.

The UNAIDS report on the global HIV epidemic said the decline was the steepest in Asia and the Pacific.

The report, “Ending AIDS: progress towards the 90-90-90 targets”, was released by UNAIDS on July 20.
It said an estimated 8000 people died from AIDS-related causes in Myanmar in 2016, a 52pc decrease from 2010.

Oussama Tawil, country director of UNAIDS Myanmar, said new HIV infections declined by 26pc. “The decline is a strong indicator of Myanmar’s national HIV response,” he said.

“This shows the country’s leadership, commitment and engagement are having results which are saving thousands of lives,” he said.

The estimated number of people living with HIV in Myanmar is 230,000, and 57pc were accessing life-saving antiretroviral therapy.

New HIV infections have fallen by 26pc since 2010, and there were an estimated 11,000 new infections in 2016, according to UNAIDS.

It said that 88pc of women living with HIV in Myanmar were accessing services for the prevention of mother-to-child HIV transmission.

The national HIV prevalence among key populations is at 28.5pc for people who inject drugs, 11.6pc for men who have sex with other men, and 14.6pc for female sex workers.

“While we are now seeing positive results in the reduction of deaths and new infections, Myanmar’s momentum must be sustained to achieve its goal of ending the AIDS epidemic as a public health threat by 2030,”said Tawil.

The National Strategic Plan on HIV and AIDS (2016-2020 aims for the achievement of global 90-90-90 targets, meaning 90pc of people living with HIV know their status, 90pc of people living with HIV who know their status receive treatment, and 90pc of people living with HIV on treatment have suppressed viral loads.

Moreover, it aims for 90pc of key populations to have access to HIV prevention services and 90pc of people living with and affected by HIV to report zero discrimination, especially in health, education and the workplace.

Tawil said that Myanmar will have challenges to end the HIV epidemic but is likely to achieve those goals.

‘’Continued commitment and support from the government, donors, international and national non-government organisations, community networks and people living with HIV groups are crucial to achieving the country’s HIV response targets,” he said.

The UNAIDS Program Coordinating Board adopted a new strategy to end the AIDS epidemic as a public health threat by 2030. The UNAIDS 2016–2021 Strategy is one of the first in the United Nations system to be aligned to the Sustainable Development Goals, which set the framework for global development policy over the next 15 years, including ending the AIDS epidemic by 2030.

Myanmar is in good position compared to other regional countries: While Myanmar has 57pc treatment, treatment coverage in some countries in the Asia-Pacific on average is only 47pc.

Haze in the South 'easing' #Thailand


Particulate measurements within safe limits in 7 provinces

 NEWS that the dire haze situation in the South has improved comes as the government launched numerous measures aimed at easing the impact of the problem on people and businesses.

The Royal Thai Air Force has even sprayed water over hard-hit densely populated areas of Songkhla province in a bid to protect the health of people.

The smog has played havoc in the Southern region for many days, as winds brought smoke from Indonesia's bush fires.

"Now, the overall haze problem has eased," Government Spokesman Maj-General Sansern Kaewkamnerd said yesterday.


He said Prime Minister General Prayut Chan-o-cha was worried about the haze's impact on people and had instructed relevant agencies to tackle the problem seriously.

The urgent measures are rainmaking operations, water spraying, the distribution of facial masks, and discussions with Indonesia over the problem.

The amount of particulate matter up to 10 microns in size (PM10), Sansern said, had not exceeded the safe limit of 120 micrograms per cubic metre of air in Surat Thani, Phuket, Songkhla, Yala, Narathiwat, Satun and Pattani as of press time yesterday.

Phuket Governor Chamroen Tipayapongtada said the haze situation in his province had shown signs of improving. He said there had not been any more flight delays because of poor visibility after 24 flights to and from Phuket were delayed between 6am Thursday to 6am yesterday.

Suratin Lianudom, a former mayor of Tambon Rassada Municipality, yesterday lodged an open letter with the Indonesian president via the provincial Phuket authority demanding that Jakarta pay serious attention to preventing the haze problem.

"Smog has affected the normal lives of people," he said in the letter.

Suratin said many tourists had been unable to connect with flights back to their home countries in time because of haze-caused flight delays.

Many children and elderly people in Phuket had developed health problems because of the haze, he said.

Yesterday, haze delayed at least four flights at Krabi International Airport, while Ranong Hospital deputy director Dr Arun Sattayapisan said the number of patients at the hospital had jumped by more than 30 per cent in the past few days because of the smog.

"Ranong doesn't have a station to check air quality. So we really don't know whether the air quality has dropped dangerously," he said.
