In Hong Kong, Cleaner Water, Dirtier Air

Ronnie Wong’s swimming career began with a dive into Victoria Harbour. In 1968, the 16-year-old competitive swimmer joined hundreds of other men and women in a 1.5-kilometre race from the Star Ferry pier in Tsim Sha Tsui to Queen’s Pier in Central.

“The moment I jumped in the water, I didn’t care about anything, just to head towards City Hall as fast as I could,” says Wong. He won the race. He won the following two years as well.

But the race, which had been launched in 1912, soon came to an end. By 1978, the harbour had become so polluted that the race was cancelled. In its final decade, Wong remembers the swim was as much of an obstacle course as it was a race. “The water was so dirty you would bump into a dead chicken or a piece of wood,” he says.

Harbour pollution continued to worsen in the 1980s. In 1988, fewer than half the city’s beaches were clean enough to swim. Locally-raised fish and oysters were so toxic the public was warned not to eat them. The “fragrant harbour,” as Hong Kong is known in Chinese, became notorious for the sickening stench of its waters.

Recently, however, things have begun to change. In the mid-2000s, Wong, who competed twice at the Olympics and is now the secretary of the Hong Kong Amateur Swimming Association, went diving in the harbour’s waters and noticed they seemed cleaner than before. “Before, you couldn’t even see a few feet in front of you, but now you can see three to four metres away,” he says.

Hong Kong Tastes Like Honey

Posted in Asia Pacific, Environment, Food, Society and Culture by Christopher DeWolf

I’ve always liked honey. Who doesn’t? But I never really understood it. Back in Canada, when I ventured into the supermarket and gazed at the various kinds of honey for sale, I was mystified by the clover honey and blueberry honey, which I bought and tried, only to find it had the same musty sweetness as any kind of honey.

That changed last month when I visited the Wing Wo Bee Farm in Hong Kong. To get there, my girlfriend Laine and I took the train to Shatin MTR station, trudged through the crowds heading to IKEA, and walked up the hilly paths that lead through the village of Pai Tau. After ten minutes, as houses gave way to thick woods, we found ourselves in front of a collection of wood boxes. Wind rustled through the leaves of the trees overhead. The warbly sound of a horn floated down from the monastery. I barely noticed the thousands of bees buzzing around.

We were greeted by the farm’s owner, Yip Ki-hok, a slight, ruddy-skinned man who spoke with the accent of his native Wai Yeung, a small town about 100 kilometres north of where we were standing. (Hong Kong, which is pronounced Heung Gong in standard Cantonese, came out as Hiong Gong when Yip spoke).

“These are Chinese bees — foreign bees need more space, they like big open fields, so they aren’t suitable for Hong Kong,” Yip said as he gestured towards the boxes, which each contain more than 10,000 bees. “They extract liquid from mountain trees. In the winter they go to ap geuk mok, these trees right above here. The flowers bloom after the winter solstice until mid-February.”

Bees in the City

It’s late on a sunny morning and Michael Leung is skulking around on the roof of an old factory building, tending to the potted flowers that feed his hungry workers: an army of 30,000 bees.

“Right now this roof is just used for smoking, but eventually we want to cover at least half of it with beehives,” he says, gathering dead plants that he was too busy to water while participating in the Detour art and design festival last December.

The hives are housed in three wooden boxes, each with a small entrance giving bees access inside. As hundreds bees pour out of the boxes, new bees arrive with bundles of pollen tucked under their appendages.

“Look,” says Leung. “Some of the pollen is yellow, some is orange.” He looked around at the surrounding walls and rooftops. His withered plants were the only green things in sight. “I’m not sure where they’re getting it. Maybe it’s one of the parks nearby.”

Leung, a 27-year-old product designer, is an unlikely beekeeper. For one thing, he didn’t know anything about bees more than a year ago. “I used to be really scared of them,” he says. Now he is the brain behind HK Honey, a new project that aims to promote local food and urban agriculture by uniting Hong Kong beekeepers and designers.

“It’s unclear where our food actually comes from,” says Leung. “The goal is to introduce local food through a creative medium.”

The Pearl River Megalopolis

Shenzhen from above

“China to create largest mega city in the world with 42 million people,” announced a breathless headline in Sunday’s Telegraph, detailing plans to combine the cities of Guangdong province’s Pearl River Delta (PRD) into a massive urban conurbation. “Over the next six years, around 150 major infrastructure projects will mesh the transport, energy, water and telecommunications networks of the nine cities together, at a cost of some 2 trillion yuan,” the British newspaper reported, noting that the new megalopolis would be “26 times larger geographically than Greater London, or twice the size of Wales.”

The news generated quite a bit of chatter as it circled around the Internet, much of it predicated on the mistaken assumption that China would be building an entirely new city of 42 million. “What about all the cities already constructed but still empty?” wrote one commenter on CNNGo in reference to the master-planned, never-lived-in city of Ordos, in Inner Mongolia. “Time to beef up security on the Hong Kong border,” tweeted a former Hong Kong resident.

The reality is less exciting. The PRD is already home to more than 42 million people and it already functions as a megalopolis with an economy worth a little under US$300 billion (about the same as the metropolitan areas of Shanghai, Boston, San Francisco and Milan). The billions of dollars in new infrastructure will complement an already well-developed network of highways, railways and waterways. In fact, the concept of a huge megalopolis tied together by roads and rail is nothing new: the Taiheyo Belt in Japan is an interconnected urban area of 80 million people linked by shikumen trains running every few minutes. Boston, New York, Philadelphia, Baltimore and Washington form a mostly interconnected urban region of more than 50 million people.

Bringing a River Back to Life

The Kai Tak River near Nga Tsin Wai Village

Wallace Chang still remembers how disgusting the Kai Tak River was when he was a child living near its banks in the 1970s. “The water was in between grey and black and it flowed very slowly, almost stagnant,” he recalls.

That didn’t stop him and his friends from going near. “We didn’t have a playground nearby so we played on the pipes that ran across the river and tried not to fall in. It was a challenge.”

It wasn’t always that way. Originally, the Kai Tak River, which runs from the Kowloon Hills to Victoria Harbour, by way of the old Kai Tak Airport, was a country stream known as the Long Jin River. During World War II, however, the Japanese Army converted it into a 2.4-kilometre drainage canal. As fields gave way to factories and squatter villages in the 1960s and 70s, the river became an open-air sewer as waste was illegally dumped into its water.

By the 1980s, the river was so polluted that passengers arriving at the airport often remarked on the foul smell. According to an old story, the comedian Bob Hope once arrived, stepped off the plane and asked what the horrible stench was. A friend informed him it was sewage. “Yes I know, but what have they done to it?” Hope replied.

Chang never did fall in the river’s foul water. He grew up to become an associate professor of architecture at the Chinese University of Hong Kong. The river changed, too. After the factories along its banks closed in the 1990s and the government cracked down on illegal dumping, the water became significantly cleaner. Fish returned and so did the birds that eat them.

Snow Isn’t So Bad After All

Posted in Asia Pacific, Canada, Environment, Society and Culture by Christopher DeWolf

It started with the new white curtains my girlfriend and I bought for our bedroom in Hong Kong. They’re opaque enough to block any potential embarrassment but shear enough to let light through, because there’s nothing I hate more than waking up in a dark room. After we installed them, they had an unintended effect. Sitting in the living room in the afternoon, my eye would wander to the bedroom, where for a second the slightly transparent curtains would trick me into thinking the window was iced over.

Later, lying in bed one sleepless night, I heard the sound of a shovel being scraped across pavement. My mind drifted to snowy nights in Montreal, when neighbours would get a head start on the falling snow by clearing their steps and front walks before going to bed. It created a peculiar chorus to the muffled hymn of car tires and footsteps trudging through the snow.

Recently, I’ve come to appreciate the seasonality of Canadian weather, which I took for granted until I moved to Hong Kong two and a half years ago. Hong Kong does have distinct seasons — I never realized 12 degrees could feel so cold until I experienced my first winter monsoon, when a chilly, dry wind blows from the north — but the differences between them are subtle. Only a small proportion of trees here lose their leaves in the winter; the best way to tell what season it is is by which tree flowers are blooming.

Clean(ish) Water at Last

Posted in Asia Pacific, Environment, Public Space by Christopher DeWolf

For years, the seven beaches along Hong Kong’s Rambler Channel presented swimmers with a conundrum: awesome views, filthy water. Pollution at the beaches was so bad in the 1990s that the government withdrew lifeguards and put up banners warning people not to enter the water.

Now, more than a decade after the beaches were closed, new sewerage and water treatment facilities have improved the water quality to such an extent that the government has deemed it clean enough for swimming. Lifeguards will return to four of the beaches next summer and the rest will be re-opened by 2013, when new changing rooms and other facilities are built.

The water quality at Anglers’, Approach, Casam, Gemini, Hoi Mei Wan, Lido and Ting Kau beaches has improved by 70 percent since 2005, according to figures released earlier this month by the government.

That improvement comes thanks to a new water treatment plant in Sham Tseng and the opening last year of a new sewerage system in the villages along Castle Peak Road, which had previously relied on leaky septic tanks. So far, 210 of the area’s 400 village houses have been connected.

“These seven beaches have been subjected to different sources of pollution from every direction since the 1990s,” said Elvis Au Wai-kwong, the Environmental Protection Department’s assistant director of water policy. Raw sewage flowed directly into the sea from restaurants and houses, a problem that intensified as the population near the beaches increased from 26,000 in 1996 to 37,000 today.

The Cheonggyecheon Experience

What amazed me most about Cheonggyecheon was its freedom. Here was a stream running through the middle of Seoul, one of the world’s largest cities, and it gurgled as contentedly as any country creek. You can walk next to the water, sit next to it, wade in and feel its sharp chill on your calves.

It becomes all the more remarkable when you realize that, ten years ago, it was little more than a sewer running beneath a traffic-clogged highway. For decades, Cheonggyecheon was buried under an expressway; it was famously restored in the early 2000s. (David Maloney wrote an exhaustive account of its history a few years ago.) When I visited Seoul last year, it was one of the things I was most eager to see, and luckily enough, I happened to be staying a short walk from it.

After the expressway was demolished, a six-kilometre linear park was built along the stream, from the business district near Gwanghwamun in the west to another river, Jungnangcheon, in the east. The stream runs several metres below street level, and descending towards the stream is a liberation from the noise and exhaust above it. Late at night, I sat next to the water and watched two couples wade into the stream, pants rolled up, giggling as they splashed around. During the day, kids played on stepping stones that traverse the water.

Cheonggyecheon is one of the best-designed examples of urban nature I have encountered. Its impact has been fare-reaching. Fewer cars enter central Seoul now and public transit use is up. Summer temperatures around the stream have been reduced by several degrees since the stream was restored.

Along the Buriganga

Ferries on the Buriganga

Ferry canoe buriganga

While railways are the nerves and sinews of India, rivers are the lifelines linking the cities and towns in neighbouring Bangladesh.

Last spring, I was in Dhaka, the congested capital, with my brother. The city of 14 million people lies on the banks of the Buriganga. After getting lost in the atmospheric narrow warren of streets in the old city for a few hours, our perspective eventually opened up upon reaching the wide, pitch-black river. Dozens of small canoes were parked on the trash-strewn riverbank. Skinny boatmen in lungis beckoned out for business with raised hands, offering to take people across. A one hour cruise can be had for a little over a dollar, probably less if you’re a miserly jerk who wants to argue over pennies.

A Chilly Fall Day? Perfect for a Swim

Posted in Asia Pacific, Environment, Public Space, Society and Culture by Christopher DeWolf

The first time I visited Beijing, almost two years ago, I had no idea about the existence of Sichahai, the three interconnected lakes just northwest of the city’s imperial heart. Built more than 800 years ago during the Jin Dynasty, the lakes later became the northern end of the Grand Canal, a 1,700-kilometre waterway that was for centuries the backbone of China’s economy. Today, they are one of the most beautiful spots in Beijing, ringed by willow trees and ancient buildings.

As lovely as they are, though, what makes them so memorable is not the scenery so much as the way they remain the setting for ordinary Beijing life. Walk north along the banks of Houhai, the largest of the three lakes, and you’ll pass by cycling hutong dwellers, people practising tai chi and playing traditional instruments. What stood out to me the first time I visited were the swimmers. It was early March and there was still ice on the lakes, so I was astonished to see a group of men emerge from the frigid water in tiny bathing suits, their skin as red as cooked lobsters.

255 Years Ago Today: The Lisbon Earthquake

On this morning 255 years ago, Lisbon was one of the richest cities in the world. Wealth had been flowing in from Portugal’s colonies ever since the great wave of Portuguese exploration began in the 1400s. A new palace and opera house had recently been completed, and the 300,000 or so residents were observing one of the biggest feasts of the church calendar, All Saints Day.

Then disaster struck in the form of a massive earthquake, estimated to be about 9 on the Richter scale of intensity (by comparison, February’s Chilean quake measured 8.8 while Haiti’s one a month earlier was 7.2). Fires and a tsunami followed, and by the time fires had burned themselves out, the waterfront and much of the sumptuous new construction was gone.

But the city was rebuilt quickly, under the guidance of a man who was, in effect, probably the greatest urbanist of his day, the Marquês de Pombal. Evidence of his leadership can be seen still in the lovely centre of Lisbon.

After the Great Fire of London in 1666, a portion of London’s centre was rebuilt along lines suggested by Christopher Wren. In the early part of the 1700s, Turin had also been expanded beyond the city walls, following plans which featured squares and streets laid on grids. Pombal, acting as the king’s right hand man, and his engineers looked to both these major changes in urban structure for ideas, but in the end forged ahead to plan a new city center that was the largest urban reconstruction project ever undertaken until Napoleon III hired Baron Georges-Eugène Haussmann to remake Paris more than 100 years later.

How to Clean Hong Kong’s Toxic Air

Posted in Asia Pacific, Environment, Transportation by Christopher DeWolf


While Hong Kong’s air is significantly cleaner than cities in mainland China, its roadside air pollution is more than five times worse than other major cities like New York

Hong Kong’s roadside air pollution hit record-high levels last month, with new data from the Environmental Protection Department showing that pollution at roadside monitoring stations reached “very high” levels for 9.5 percent of the time in July, August and September. The previous record, set in 2004, was 8.2 percent.

The findings have added to growing alarm about the impact of roadside air pollution. Even as Hong Kong’s overall air quality improves, pollution in the streets is getting worse. But unlike other environmental problems, like climate change, environmentalists say there are a number of straightforward ways of dealing with roadside air pollution, by implementing stricter emission controls and reducing the amount of traffic on the streets.

“When the streets in Central are pedestrianized on Sundays, the air quality is fine, but on normal working days, it keeps getting worse,” says Hung Wing-tat, an associate professor of civil engineering at the Polytechnic University and a director of the Conservancy Association, a green group that has been lobbying the government for more action on air pollution.

Life Under the Landing Gear

Posted in Environment, History, United States by Christopher Szabla

The approach to Hong Kong’s old Kai Tak Airport was notorious: planes that swooped down toward its runways passed so close to the rooftops of Kowloon City that they practically risked tangling their landing gear in laundry lines. Nearly thirty years ago, life on Neptune Road, hard by Logan Airport in East Boston, wasn’t quite so dramatic. But the noise pollution resulting from planes descending near its closely-packed triple-deckers was bad enough for the Environmental Protection Agency to become involved in monitoring the neighborhood’s habitability.

The EPA’s agents didn’t arrive in the area alone. As part of the agency’s Documerica project, dedicated to chronicling the environmental problems of the 1970s, photographer Michael Philip Manheim joined them, capturing the lives of residents living on and around Neptune Road. Recently, his 1973 collection of photos from the neighborhood became available, along with the rest of the Documerica photographers’ work, on the U.S. National Archives’ Flickr account.

There’s no longer a noise problem in Kowloon City, which has been free of din since Kai Tak Airport shut down in 1998. Neptune Road, too, has grown relatively quiet — but not because of any changes made at Logan. Beginning shortly before Manheim shot its streets and accelerating through the 1970s, the neighborhood was systematically acquired by Massport, the agency that runs the airport, and almost entirely demolished. Manheim’s photos are now among the few records of one of Boston’s long-forgotten corners.

Hong Kong’s Air Conditioning Addiction

It was just one night but it seems most people in Hong Kong could not go without air conditioning. Last Wednesday, about 50,000 households switched off their air-con units for Hong Kong’s first No Air Con Night, an event organized by the eco-group Green Sense to raise awareness of the environmental impact of air conditioning.

But for the remaining 2,285,000 homes in the city, it was business as usual.

“I tried to sleep without the A/C on, but it was too noisy to keep the windows open and the room heated up so fast,” one Mongkok resident said.

In just a few decades, Hong Kong has evolved into an air-con dependent city, with most people spending their days in housing estates, shopping malls and office towers that become furnaces without the cooling systems. The dependence continues at night as temperatures soar in our high-rise, heat island homes. So much so that air con accounts for 60 per cent of the city’s power consumption in summer.

When it comes to air conditioning, we seem to have built ourselves into a corner. Now, some are looking for a way out.

“Even in the 1990s, schools were not air conditioned, many buses had no air con and there were not as many shopping malls,” said Gabrielle Ho, the project manager of Green Sense. “Now the first thing people do when they get home is switch on the air con. Everywhere is so air-conditioned, people have gotten used to it.”
