The Green, Green Grass of China

ENVIRONMENT — New Canadian citizen planted 160,000 trees in 2008 Olympic host city

Jonathan Fowlie – Vancouver Sun – Friday, May 23, 2008

BEIJING – By all accounts, Sharon Li is a private woman, but as the world gets ready to descend on this city of air pollution and skyscrapers, she is about to make a giant impression.

Li, a recent Canadian citizen who splits her time between Richmond and China, owns 100 hectares in the 680-ha Olympic Forest Park just north of the Bird’s Nest stadium.

Over the last three years, the chairwoman of SenAo Culture and Art Development Co. Ltd. has been converting the land into an undulating vista of grass, water and trees so tranquil that visitors almost forget they are in China’s second-largest city.

In total, Li has planted 160,000 trees on the land, nearly 50,000 of them relocated from the site of the Three Gorges Dam.

She has also helped Canadian officials to establish the B.C. Canada Pavilion, which opened for its first full day Friday.

However, she refuses to talk about her work or take credit for any part of what she has done.

“I don’t need praise. I don’t need interviews,” she said Friday afternoon while perched in a chair beside a large pond.

“I just like working in the background silently.”

“I think it belongs to a lot of people,” she said of the park. “It’s not just about me.”

Li did, however, receive B.C. Premier Gordon Campbell when he made a brief visit to the park Friday. She told him she has bought 300 old heritage homes she plans to have reconstructed on the land. She added that she has moved a total of 320,000 trees from the Three Gorges Dam site but said most won’t grow in Beijing, so she donated them to a school in Shanghai.

Li said she would like to see some of those trees planted at a Canadian pavilion planned for Shanghai to coincide with the 2010 World Expo.

Campbell, who was in the park to plant a tree, agreed the relocated trees would fit nicely into the Shanghai pavilion.

Afterwards, he remarked on how impressed he was with Li and her achievements.

“What a great citizen! It’s a really exceptional example of what citizens can do when they put their minds to it.”

On Friday, workers throughout the park were still laying sod, planting trees and landscaping areas of the massive park, which is located in the north of Beijing.

Green Brothers To Tackle China’s Environmental Crisis

In pod we trust

An unlikely trio adopts a fun approach to spread the green message on the mainland

Dinah Gardner – SCMP – Updated on Apr 14, 2008

Take a geeky-looking US student, an idealistic young mainlander, and an actor from Toronto, mix in video, some naff rap lines – “Wind energy, hey/ Reduce emissions, hey/ It’s green energy/ Hey! Hey! Hey!” – and the result is the China’s Green Beat website.

Calling themselves the Green Brothers, the unlikely trio of John Romankiewicz, Zhao Xiangyu and Rene Ng have been highlighting efforts to tackle China’s environmental crisis through quirky videos that they post on their site, and now hope to persuade young people that it’s hip to be green.

A visiting Fulbright scholar, 24-year-old Romankiewicz says they got the idea for the podcasts while he was tutoring Zhao in English. “Each time we met, we ended up spending all our time discussing China and the environment,” he says.

Green Beat started last September as a blog funded with remaining money from Romankiewicz’s scholarship, but has since grown into a website (chinasgreenbeat.com) with five podcasts posted so far. Made in Putonghua with English subtitles, the earlier videos by Romankiewicz and Zhao, 20, featured topics such as Beijing’s recycling system, solar water heaters and biomass power plants.

The more recent addition of Canadian actor-director Ng, 32, who runs the Beijing International Theatre and Entertainment stage group, has injected more polish and humour into the productions. Take the episode titled Sun Zhe’s Transportation Adventures, in which the Green Brothers (kitted out in urban streetwear and comically dazzling bling) rap about the merits of public transport. The hero finds he becomes attractive to girls as soon as he starts taking the subway.

Such humorous efforts have won the brothers a growing number of fans, increasing respect and, more recently, international sponsorship. Last week, with help from China Dialogue, an international NGO with an environmental focus, they conducted a two-day workshop to teach university students how to make Green Beat-style videos.

The 30 participants came from all over the country – each representing a green group from their university – with 10 from Beijing and the remainder ranging from Xinjiang in the northwest to the manufacturing city of Wenzhou on the east coast.

Lacking the flash adopted by some larger NGOs, the workshop took a down-to-earth stance: the venue was a two-star hotel in the university district of Haidian and speakers were volunteers and students who took the bus to a recycling depot to practise shooting video.

Warming to Romankiewicz’s Putonghua efforts, Ng’s humour and Zhao’s enthusiasm – “This is just my passion,” he says – the participants exchanged real-life experiences and many came away fired up with ideas for producing their own podcasts.

They have a month to finish the assignment and the best short will win a 1,000 yuan (HK$1,115) prize.

Gao Wei-wei, a first-year law student at the University of Hong Kong, was touched by mainland participants’ tales of how their home villages had been poisoned by pollution. “My blood is boiling … to listen to these people’s stories from all over China,” she says. “Their stories took my breath away.”

The 19-year-old is already planning a video on excessive consumption in Hong Kong. “Hong Kong people are so materialistic. They waste so much,” says Gao, who views unsustainable consumption as the biggest threat to the environment in the region.

China Dialogue estimates there are now about 2,500 student environmental groups in the country. The number has grown steadily over the past decade, ranging from tiny groups such as Green Eyes, which was founded by a 17-year-old schoolboy eight years ago, to the sprawling China Youth Climate Action Network, which links climate change activist groups across the country.

Although the authorities tend to be wary of student movements, the green groups survive because they’re apolitical – there’s nothing subversive about picking up litter or encouraging people not to use plastic bags. “Green student groups don’t do anything controversial … it’s a pretty safe arena,” says Romankiewicz, who also researches renewable energy issues as an intern for information provider New Energy Finance.

And Green Beat is careful to keep it that way: at the workshop, students are told to avoid political comment when making the podcasts. “There’s no need at this point to make this political,” he says.

A graduate in materials science and engineering from Northwestern University, Romankiewicz says he was spurred into starting Green Beat by the pessimistic tone that foreign media took in covering environmental problems on the mainland.

Western reporters give the impression that the situation is hopeless, but there are good things going on, he says. “And the best way to inspire and encourage people to lead greener lives and make greener investments is through smart, fun and optimistic media.”

Romankiewicz rejects suggestions that Green Beat’s podcasts might lack bite. “You should be somewhat balanced and in the next few videos we’ll just be straight up,” he says. “But you can’t just make a video about pollution, saying it killed 20 people and then leave the viewer with no answers about how to solve this … there must be something people can do.”

The podcasts help show a more rounded picture of mainland efforts to heal environmental scars, says Zhao, who grew up in the coal-mining town of Qitaihe in Liaoning province. “We’re sick of western media only showing part of the truth with the environment story,” he says. “If you are a country with 1.3 billion people, how can you deal with this situation?”

Workshop participants such as Hou Xiaoting reckon Green Beat’s wacky methods work. “They’re doing really cool stuff, it’s a new way to promote the environment and it can attract a lot of people’s attention because it’s funny,” says the 23-year-old from Fudan University in Shanghai.

But given the gravity of China’s environmental woes, what can a group of students on a shoestring budget hope to achieve? The mainland is now the world’s biggest emitter of greenhouse gases and contains 16 of the world’s most polluted cities. Expanding deserts now cover about one quarter of land surface and, despite the central government’s enthusiastic initiatives, local officials obsessed with growth and wealth rarely take heed.

Zhao reckons the answer lies with young people. “Maybe these students can’t change the situation now, but in the future they will get jobs, they’re the future.”

The students agree. “A lot of Chinese people, including many young people, feel frustrated, but I have hope in this country,” says Zhao Yue, a 22-year-old from Liaoning now studying earth sciences at the University of Hong Kong. “I believe change is around the corner.”

Report: Identifying Dominant Sources of Respirable Suspended Particulates in Guangzhou, China

Yu Song, Wei Dai, Xuesong Wang,* Mingming Cui, Hang Su, Shaodong Xie, and Yuanhang Zhang, Department of Environmental Sciences, Peking University – January 1, 2008

Abstract

Respirable suspended particulates (RSP, i.e., particles with an aerodynamic diameter of 10 μm or less) were measured in 2004 and 2005 at seven sites in the rapidly developing Guangzhou area of China. The average RSP concentration was 126 μg m-3, a high level that could be very harmful to human health. The chemical species composition of the RSP, including organic and elemental carbon, water-soluble ions, and elemental compositions, was also analyzed. The organics and sulfate may be the major components of RSP mass concentrations. Positive matrix factorization (PMF) was used to identify the sources of RSP as secondary sulfates (32%), secondary nitrates (6%), biomass burning (15%), coal fly ash/cement (18%), sea salt (3%), crustal dust (5%), vehicle exhaust (6%), and coal-fired power plants (3%). Reducing coal combustion and controlling vehicle emissions would alleviate RSP pollution, as most of the precursors were components of coal burning emissions and vehicular exhaust.

Conclusions

Guangzhou, a rapidly developing megacity in China, suffers from a high level of RSP pollution. Our results show that organics and sulfate were dominant in RSP mass concentrations. Climatologic conditions, that is, high temperature, high RH, and strong solar radiation, determined by the geographic location of Guangzhou (low latitude and proximity to the sea), resulted in high rates of VOC transformation to secondary organics and SO2 transformation to secondary sulfate. However, ammonium nitrate was unstable at high temperatures. These results also demonstrated the spatial
variability of RSP levels. Urban and industrial areas often had higher levels of RSP pollution. Source apportionment identified three major sources contributing to RSP pollution: secondary products, coal fly ash/cement, and biomass burning.

To alleviate RSP pollution in Guangzhou, some control measures should be implemented. First, reducing or replacing coal-fired power stations with advanced coal gasification technologies and desulfurizing the smoke emitted by coal-fired manufacturing plants could be important pathways to control SO2 and coal fly ash emission. These methods could help abate the secondary sulfate and coal fly ash in RSP. Second, public transportation such as subways and buses should be improved to limit the further increase in the number of automobiles, given that more than 80% of vehicles in Guangzhou were private cars. The gaseous precursors of NOx and VOCs emitted mostly from motor vehicles could be transformed to SOC and secondary nitrate. Third, growing grass or paving bare surfaces may limit the amount of cement dust entering the air. Construction projects should be well managed. Finally, the contribution of biomass burning was high in Guangzhou, especially in suburban areas. Some measures should be implemented to control these cultivation activities in farmlands. It is important to note, however, that atmospheric pollution is a regional problem, and the government of Guangzhou will need to negotiate with other administrations to control RSP levels in the study area.

The factor analysis method is only one way to apportion the sources of RSP; other methods, such as the bottom-up approach, should be implemented to obtain the source inventory in the future. Accurate source profiles should also be measured to better represent the conditions in Guangzhou and may be better applied in the multivariate method. Although seven sampling locations were used in this study, the number of sites is insufficient for evaluation of RSP pollution across Guangzhou; dispersion models, for example, MODEL-3 and CAMx, that include physical and chemical
processes, could solve this problem.
