cambodian-villagers-say-dam-construction-is-forcing-endangered-dolphins-upstream-due-to-noise-from-the-dam-construction-site

Cambodian villagers are worried that the few remaining Irrawaddy dolphins in a pool in the Mekong River could die off as they are forced to migrate upstream into Laos to escape disturbances caused by the construction of a massive hydropower dam project, local residents and activists said Thursday.

Only three endangered Irrawaddy dolphins, also known as Mekong River dolphins, are now left in the Cheuteal transboundary pool between southern Laos and northern Cambodia’s Stung Treng province, whereas eight were in the area in 2010.

Members of the Preah Rumkel ecotourism community in the province’s Thalaborivat district said Irrawaddy dolphins have been moving two miles upstream into Laotian waters because of noise from explosions at the construction of the 260-megawatt Don Sahong Dam along the Mekong River in southern Laos, less than a mile from the Cambodian border.

The small Mekong River village of Preah Rumkel was set up in 2007 with assistance from an environmental NGO as a community-based ecotourism site to support the local community and improve residents’ livelihoods. Community members manage the tourism site themselves. The half-completed dam lies about one kilometer (0.6 mile) away from the community.

Besides the noise from the dam construction site, the chemicals discarded into the river by construction workers have also forced the dolphins upstream, said Phay Vanna, a member of the Preah Rumkel ecotourism community.

He said he wants the Cambodian government to hold Laos, which is building the dam, accountable.

“I would like the prime minister and civil society organizations to send some experts to conduct additional feasibility studies to hold Laos accountable for the impact caused by the dam’s construction,” he said. “I am a community member. I have witnessed the real impact.”

Gone for good?

Residents are also concerned that their incomes will fall as fewer tourists visit the area when the dolphins are gone for good.

Once in Laotian waters, the Irrawaddy dolphins may succumb to gill nets—vertical panels of nets lined up across a river to catch fish—whose use is not prohibited in Laotian waters as it is in Cambodian ones.

Switzerland-based World Wide Fund for Nature (WWF) says use of the nets is one of the main reasons for the decline in the population of Irrawaddy dolphins, which become entangled in the nets and drown.

The organization wants gill nets banned from a two-kilometer (1.2-mile) radius around the Cheuteal Pool, where they are currently in use, and increased enforcement against fisherman who violate the ban.

Huoth Seng, a Preah Rumkel villager, said he is not happy with recent remarks by Cambodian Prime Minister Hun Sen regarding his approval of the Don Sahong Dam.

On Nov 23, during a meeting in Siem Reap with leaders from Laos and Vietnam about development in the Golden Triangle area, Hun Sen said feasibility studies had been conducted and that the dam project would have no impact in terms of lack of water or fish migrations.

But the dam construction is affecting several thousand families who rely on selling souvenirs, accessories, and food to tourists who come to see the dolphins, he said.

“I didn’t see any transnational studies or research on the impact of the dam project,” he told RFA’s Khmer Service. “What I have seen is that the project is implemented. Now that the communities have been impacted, I wonder who will be held accountable.”

‘We don’t agree with him’

Civil society groups also accuse the prime minister of turning a blind eye to other issues related to the dam’s construction that are affecting thousands of people in the area.

Ek Chamroeun, coordinator of the Fisheries Action Coalition Team (FACT), a group of NGOs that advocate for fisheries issues and monitor policy reforms, said the dam project has also been a disaster for food security.

“Though Hun Sen said there is no impact, we don’t agree with him,” he said. “We are concerned because we see the real impact on the communities regarding the dam project.”

According to WWF, the Irrawaddy dolphin population has dropped by 50 percent this year in Cambodia, and the large aquatic mammals are functionally extinct in Laos with too few potential breeding pairs available to ensure the population’s survival.

About 80 Irrawaddy dolphins remain in the Mekong River in Cambodia.

Japan to compensate 3,400 residents over US base noise nuisance

The Japanese government has been ordered to compensate around 3,400 residents living near the US military base in Futenma for various inconveniences, including loud noise leading to distress and insomnia.

Following similar rulings in 2010 and 2015, the Naha district court in Okinawa asked Japan to pay 2.46 billion yen ($22 million) in damages to the plaintiffs, Efe news reported.

The court ruled in favour of thousands of locals, who had filed a class action suit demanding 10 billion yen in damages for distress and insomnia caused by the din from the base.

However, the petitioners’ demand for suspension of flights was rejected.

While the Futenma air base, spread over 480 hectares, is currently located in the central area of the city of Ginowan, surrounded by houses and public buildings, Tokyo and Washington had decided to move it out to a less densely populated area on Okinawa island in Henoko coastal area.

In June 2015, the same court had ordered damages worth 754 million yen for around 2,200 people, while 2010 saw another court asking the administration to cough up 369 million yen in compensation, while dismissing demands to halt flights at the base.

Okinawa houses over half of the nearly 47,000 US soldiers, and 74 per cent of American military installations, in Japan.

Karachi: Hazardous noise pollution

Karachi: Hazardous noise pollution

Hazardous noise pollution

M Wasif Masood

The insensitive use of load speakers has become a nuisance in Karachi, especially in Gulistan e Johar, block 14 residential area.

The builders paid a handsome amount to all concerned authorities to convert that particular residential area into expensive commercial space and the entire residential area is now housing the the Banquets Halls and Wedding halls. The most annoying thing is the loudspeakers they used till late night. People seem to believe that every occasion like marriages and birthday parties would be incomplete without the blaring of loudspeaker and fireworks.

karachi-noise-hazard
karachi-noise-hazard

Noise pollution is already one of the greatest problems that people living in Karachi have to deal with. The excessive use of loudspeakers makes it even worse. Of course there are occasions when their use is necessary but I see no justification in using them in residential areas. All elite Ministers are living in peace but they should think about the peace of common taxpayer too.

The worst hit by this improper use of loudspeakers in residential areas are elderly and the children. Due to excessive noise the elderly cannot sleep properly and the children cannot concentrate on their studies. Will the concerned authorities intervene and do something to regulate these issues and bring the officials to book who gave permission to run a marriage hall in residential area.

Many ways to reduce urban noise in China

Many ways to reduce urban noise in China

According to a recent report issued by the Ministry of Environmental Protection, a quarter of Chinese cities exceeded the limits on noise pollution last year. Beijing News commented on Monday:

Chinese residents are no stranger to noise pollution, ranging from late-night construction to daytime traffic. They suffer from a variety of noises on a daily basis, but their complaints are often ignored or not dealt with properly.

Noise pollution, in effect, can be as harmfull as air, water and soil pollution, as it is a major cause of insomnia, even heart attacks.

There have been successful attempts to curb noise pollution in some countries. In Japan, construction sites are always surrounded with heavy shields to prevent noise and dust from spreading out. Germany has specific limits on road decibels and has applied noise reducing technology to its roads.

In comparison, China’s solutions to the noise problems, be they technological or legislative, still lag far behind. Neither the environmental protection authorities, who are supposed to take care of industrial noise, nor the police that should play a role in curbing traffic noise do their job properly. And public complaints about urban noise pollution often fall on deaf ears.

Building roadside shields should be a viable solution to traffic noise pollution. But they are poorly built even absent in many cities due to the lack of cooperation among departments. The noise pollution policies need to have more teeth to effectively tackle the problem.

Immersion sound check for old buildings

KOLHAPUR: The dilapidated buildings along the Ganesh idol immersion routes are turning out to be the biggest concern for the civic authorities.
On the one hand, the Kolhapur Municipal Corporation (KMC) has issued notices to the tenants of 45 such buildings to vacate the structures fearing high-decibel sound can damage those and lead to accidents. On the other hand, it wants the mandals to keep the sound level low along the stretches dotted with the dilapidated buildings to avert any accident because of the high-decibel beats.
The KMC had identified these dilapidated buildings during a survey held a couple of years ago. The civic authorities have now now written to the police administration to ensure that the tenants in the buildings are not present inside at the procession time. If possible, the KMC wants these people to be relocated somewhere else till the procession ends.
The KMC has termed these building dangerous to live in after a structural audit and even disconnected water and electricity supply to ensure the tenants leave. But over the last one month, the KMC has stopped the drive to remove residents of the dangerous buildings.
The civic authorities claimed that most tenants in these buildings were in legal disputes with the respective owner. “The KMC cannot demolish these buildings in the absence of any legal provisions in such a situation,” a KMC official said. Records available with the divisional ward offices reveal that over 40 such buildings should be demolished at the earliest. There are over 90 dilapidated buildings in the city.
KMC divisional engineer S K Mane said, “Through the notice, we have asked the tenants not to stay in the buildings until the processions end. No one should stand on the balconies as they may collapse due to the high-decibel sound. We had asked the tenants and owners to remove the buildings on their own last year. The KMC will not be responsible for any casualty if such a building collapses. Police have been asked to vacate these buildings during the immersion procession.”
Sources said the civic authorities have sought permission from the district administration to demolish the buildings. But the district authorities require more time to study the legal disputes before ordering demolition. Most Ganesh mandal processions pass through Deval Club, Mirajkar Tickti, Mahadwar Road, Papachi Tickti and Gangavesh.

Almost all the dangerous buildings are located along the immersion routes of the major mandals, that use high-decibel sound system to attract revellers, particularly the youth. The immersion procession lasts for more than 24 hours. Pandals of many political parties are also set up along the immersion routes and such sound systems are used for announcements.
“We have installed CCTV cameras along the immersion routes to keep a watch and avert any untoward incident. In case of the dilapidated buildings, we have asked police to ensure that enough space is left between the procession and the building so that rescue operations can be carried out effectively if there’s an emergency. The list of the dangerous buildings along the immersion route will be circulated to the mandals, so that they can reduce the sound volume. Police are entitled to frame charges against mandals if any such building collapses because of the high-decibel sound,” Mane said.
The noise levels should not exceed 50 decibels (dB) in the hospital areas, while the cap is 55db in the residential areas (see graphics). Last year, police had booked 62 mandals for flouting the noise norms. The civic authorities said the dilapidated buildings may not sustain any sound above 80 dB.
Mahendra Shelke, a resident of Malkar Tickti, said, “This year, police have categorically asked the mandals not to use Dolby system during the immersion processions. Even if any accident occurs, the mandals are not held responsible because of their influence. The procession routes should be changed as most of those pass through the congested and old city areas dotted with old buildings.”

PORTABLE NOISE MONITORING TECHNIQUE AIMS TO IDENTIFY AND MAP OUT NOISE POLLUTION

August Schiess, University of Illinois at Urbana-Champaign
09/01/2016
Urban noise is sometimes seen as merely a harmless annoyance for people who live near busy streets or train stations, but it can cause health problems such as sleep disturbance, hearing loss, hypertension, and heart-related diseases.

Arrays are mounted to the top of an electric vehicle to measure noise levels.
Arrays are mounted to the top of an electric vehicle to measure noise levels.
Researchers have therefore been seeking ways to understand and combat the rising levels of urban noise. A team at the Advanced Digital Sciences Center (ADSC) has developed a signal processing technique that measures urban noise through portable microphones secured to the top of a moving vehicle, enabling the creation of a wide-ranging map of noise pollution.

“With a comprehensive understanding of the levels and types of noise pollution in urban areas, we can then analyze this information to create well-designed soundscapes that can alleviate the bad effects of environmental noise on physical and mental human health,” said Cagdas Tuna, a postdoctoral researcher at ADSC, a University of Illinois research center in Singapore.

Current noise-monitoring techniques are built into microphones fixed to the ground—they only measure sound from that vantage point, making a city-wide noise map an incredibly expensive idea. However, with the team’s portable solution, sound can be measured in as many locations as possible in the neighborhoods travelled by the vehicle.

To gather acoustic signals, they mount a microphone arrangement on an electric vehicle—the quiet engine keeps it from interfering with other external sounds. While driving along, the sensors identify a variety of noises and can pinpoint the location of sounds in relation to the vehicle.

Advanced signal processing tools recover and generate the noise-sources into an acoustic map at multiple frequencies.

“We have developed several different acoustic imaging algorithms, based on the multiple-location measurement scheme, to generate 2D acoustic maps,” said Tuna, a University of Illinois alumnus in electrical and computer engineering. “The maps show the noise-levels and locations of dominant noises.”

The team has been testing the new technique on Singapore streets over the past year. Tuna, who presented this work at the 23rd International Congress on Sound & Vibration (ICSV23) in July 2016, will continue to develop this technique by collecting more measurements around noisy areas such as construction sites.

This acoustics team at ADSC working on the project includes CSL and ECE Professor and ADSC Director Doug Jones, Tuna, Shengkui Zhao, ADSC research scientist, and Thi Ngoc Tho Nguyen, ADSC Senior Software Engineer.

NO HORN, PLEASE. WE ARE INDIA’S SECOND NOISIEST

By: Aparna Anil; http://www.bangaloremirror.com/

In the first part of our campaign, we look at honking, the bane of eardrums across city

The incessant blare of horns is a background score that almost every Bengalurean has come to live with. But what if we were to tell you that 93.7 per cent of people who use their horns do so for no reason whatsoever: that’s what a recent study discovered. In fact, the study claims that Bengaluru is India’s second noisiest city when it comes to honking.

“From the results of the three-day survey conducted as part of a ‘Culture of the City’ study, looks like people of Bengaluru imagine there is a Right to Honk,” says Harish Bijoor, who heads the consulting firm that performed the study for a multinational company. “Bengaluru, today, stands as the second noisiest city in India,” he says, adding that he could not divulge details as to which city topped the list due to the nature of the study.

If you go by that, things have got worse because a few months ago, the Central Pollution Control Board (CPCB) labelled Bengaluru India’s sixth noisiest city.

The high decibel level in Bengaluru is mostly an offshoot of frustration. The study finds: “Forty-two per cent of people honk because the traffic is moving slowly. Another 41 per cent says they honk because others drive badly, “says Bijoor. He adds that the survey’s responses showed that people often used honking like a swear word.

The responses included: “If I don’t honk, somebody else will”, “It is my way of telling them they are wrong”, “It is a way of me using bad language”, etc. “Honks categorised as necessary are those that can avoid an accident or save a life,” says Bijoor elaborating on the categorizations. Those are cases where people honk to caution somebody of their vehicle’s presence when it’s absolutely necessary, or when they honk to attract the attention of an animal crossing the road, which cannot be alerted otherwise.

Another interesting side the study focused on the honking habits of cab drivers – both those who work for cab aggregators and individual drivers. The results showed that drivers who work cab aggregators always tend to honk more than others.

The study also found that women drivers honk less than their male counterparts. “If we take the rate of honking on a scale of 10, then women would be 2, whereas men would be around 8.6,” says Bijoor.

The qualitative study was conducted by deploying 80 people at 80 different junctions in the city .They were deputed for collecting both direct responses from drivers and making observational recordings. Conducted on a sample of 48,000 people, the study has come up with a representative map of the honking intensity at these junctions.

“As this survey was conducted for a global organization, we cannot reveal the exact findings as to which part of the city is the noisiest,” says Bijoor.
The response to the study shows that a majority of Bengalureans see honking as a part of life. They are not particularly annoyed by it and neither do they think of proactive measures to bring down the decibel levels.

The study focusing on the noise levels in cities is also an attempt to look at the decibel levels in third world countries. “Usually, the noise levels in third world countries tend to be higher,” says Bijoor.
