[ScienceDirect, via Biblio-SHS] Auteur : Shuxiao Wang, Jiming Hao Paru dans : Journal of Environmental Sciences, Volume 24, Issue 1, January 2012, Pages 2-13 Abstract This article analyzed the control progress and current status of air quality, identified the major air pollution issues and challenges in future, proposed the long-term air pollution control targets, and suggested the options for better air quality in China. With the continuing growth of economy in the next 10-15 years, China will face a more severe situation of energy consumption, electricity generation and vehicle population leading to increase in multiple pollutant emissions. Controlling regional air pollution especially fine particles and ozone, as well as lowering carbon emissions from fossil fuel consumption will be a big challenge for the country. To protect public health and the eco-system, the ambient air quality in all Chinese cities shall attain the national ambient air quality standards (NAAQS) and ambient air quality guideline values set by the World Health Organization (WHO). To achieve the air quality targets, the emissions of SO2, NOx, PM10, and volatile organic compounds (VOC) should decrease by 60%, 40%, 50%, and 40%, respectively, on the basis of that in 2005. A comprehensive control policy focusing on multiple pollutants and emission sources at both the local and regional levels was proposed to mitigate the regional air pollution issue in China. The options include development of clean energy resources, promotion of clean and efficient coal use, enhancement of vehicle pollution control, implementation of synchronous control of multiple pollutants including SO2, NOx, VOC, and PM emissions, joint prevention and control of regional air pollution, and application of climate friendly air pollution control measures.

With rapid economy growth, building energy consumption in China has been gradually increased. The energy consumption and indoor environmental quality of 51 office buildings in Hainan Province, a hot and humid area, were studied through collection of verified data in site visits and field tests. The result revealed that, electricity accounted for 99.79% of the total energy consumption, natural gas 0.17%, and diesel 0.04%. The air conditioning dominated the energy use with a share of 43.18%, equipment in the particular areas 26.90%, equipment in the office rooms 11.95%, lighting system 8.67%, general service system 7.57%, and miscellaneous items 1.73%. Statistical method including six indicators obtained the energy consumption benchmark with upper limit of 98.31 kW·h/m2 and lower limit of 55.26 kW·h/m2. According to ASHRAE standard (comfortable standard) and GB/T 18883-2002 (acceptable standard), the indoor environmental quality of 51 sampled office buildings was classified into three ranks: good, normal and bad. With benchmark of building energy consumption combined with indoor environmental quality, it was found that only 3.92% of sampled buildings can be identified as the best performance buildings with low energy consumption and advanced indoor environmental quality, and the buildings classified into normal level accounted for the maximum ratio.

Sur le site "The Urban China Initiaitve" 4/05/2012 By Li Jing ( China Daily) Urban leaders do more to safeguard environment, conserve resources Small and medium-sized cities are more livable than big cities such as Beijing and Shanghai gauged by their air quality, waste treatment capacity and built environment, according to newly published research by Urban China Initiative. A woman rides a bicycle on a windy day in Beijing. According to recently published research by Urban China Initiative, Beijing and Shanghai were absent from a ranking of the top 10 Chinese cities gauged by their environmental sustainability. [Photo/China Daily] UCI, a think tank launched by Tsinghua University, McKinsey & Co and Columbia University, gauged the sustainability of 112 major Chinese cities using 17 indicators in four categories - society, economy, environment and resources. Beijing ranked first in sustainability thanks to its heavy investment in social welfare - including social security, education and healthcare - and its economic achievements. The top 10 cities in overall score - including Xiamen, Fujian province, Haikou, the capital of Hainan province, Dalian in Liaoning province, and Shanghai - are all medium and large-sized cities. However, small and medium-sized cities are taking the lead in environmental sustainability. Both Beijing and Shanghai were absent from the top 10 in this category. According to the research, Haikou has the best air quality, while Hefei, capital of Anhui province, took the lead in waste treatment facilities. And Xining, the capital of Qinghai province, boasts the best built environment - man-made surroundings that serve as the setting for human activity. "Such a result shows that small cities have a better quality of life, though people living in megacities like Beijing and Shanghai have better access to medical and educational resources," said Jonathan Woetzel, co-chair of UCI, as well as a senior global dir

"Among all the ancient traditions that Chinese people observe during the lunar New Year, setting off firecrackers is the most controversial. Originally used to "drive bad luck away," firecrackers have been an intrinsic part of the Chinese New Year celebration for thousands of years. Yet, their contribution to air and noise pollution has always incurred debates about whether they should be banned. This year, the debate has been intensified by the severe air quality crisis many cities faced right before the festival. TLNLogo_Horizontal-215 MORE FROM TLN China Isn't Apple's Only Supplier A Confusing Flowchart for the Confused Chinese Traveler Chinese Web Users Weigh in on North Korea's Nuclear Test Towards the end of January, citizens in Beijing endured several waves of what many Western media outlets dubbed "airpocalypse." On January 29, the air quality index released by the U.S. embassy in Beijing peaked at 526, beyond "hazardous" and literally off the charts. Responding to the environmental disaster, many Web users spontaneously advocated to stop setting off firecrackers during the upcoming festival. A comment tweeted by Shi Shusi(@石述思), the editor-in-chief of the Workers' Daily, is representative. "Entering middle age, I suddenly realize that the majority of my family consists of seniors and children. So although I've loved firecrackers since childhood, I decided to quit using them for the sake of both tranquility for my family and clearer air. I request earnestly that everyone set off fewer firecrackers, and while doing it, try to keep your distance from seniors and children." As the anti-firecracker web users' voices multiplied, accounts of official media joined the campaign. China Central Television's Economics and Finance Channel (@央视财经) is one of them. "The air quality in Beijing has become poorer and poorer as we approach the New Year. If we still set off firecrackers, the air quality will not be not restorable. Here, our channel

DOI: http://dx.doi.org.gate3.inist.fr/10.1016/j.landusepol.2011.11.010 [ScienceDirect, via Biblio-SHS] Auteur : Jing Wang et al. Paru dans : Land Use Policy, Volume 29, Issue 4, October 2012, Pages 737-749 Abstract China has extremely scarce land resources compared to the world average. There is an urgent need for studies of the current situation and the trends in land-use change and assessment of the performance of land policies in China. Assessment of land-use change has long been hindered by a lack of accurate and reliable data. This paper uses the data obtained from the national land surveys of 1996 and land-use change surveys from 1997 to 2008, to analyze changes in land use and the policy dimension driving forces related to the changes, especially cultivated land, forestry land, grassland, as well as developed land. The aim of this analysis will be to derive the physical, social and economical driving forces of those changes to grasp the trends in land-use change and the effects of land policies and to formulate strategies for the protection and sustainable use of agricultural land. The results indicate that, although the overall change in land use was not large, cultivated land was significantly reduced and developed land rapidly increased. A great deal of high quality cultivated land was changed to developed land and low quality cultivated land generated from unused land, which has resulted in a serious threat to food supplies in China. Predictions using the methods of linear extrapolation and a BP neural network indicate that it is impossible to keep to a target of 0.12 billion hectares of cultivated land in the future under the mode of economic development used between 1996 and 2008. The results also indicate that the implementation of the laws and regulations about controlling the developed land and preserving cultivated land had significant effects on changes in land use, especially cultivated land and developed land. The results sugges

Thématique n° 2 [ScienceDirect, via Biblio-SHS] Auteur : Jing Wu, Joseph Gyourko, Yongheng Deng Paru dans : Regional Science and Urban Economics, Volume 42, Issue 3, May 2012, Pages 531-543, Special Section on Asian Real Estate Market Abstract High and rising prices in Chinese housing markets have attracted global attention. Price-to-rent ratios in Beijing and seven other large markets across the country have increased by 30% to 70% since the beginning of 2007. Current price-to-rent ratios imply very low user costs of no more than 2%-3% of house value. Very high expected capital gains appear necessary to justify such low user costs of owning. Our calculations suggest that even modest declines in expected appreciation would lead to large price declines of over 40% in markets such as Beijing, absent offsetting rent increases or other countervailing factors. Price-to-income ratios also are at their highest levels ever in Beijing and select other markets, but urban income growth has outpaced price appreciation in major markets off the coast. Much of the increase in prices is occurring in land values. Using data from the local land auction market in Beijing, we are able to produce a constant quality land price index for that city. Real, constant quality land values have increased by nearly 800% since the first quarter of 2003, with half that rise occurring over the past two years. State-owned enterprises controlled by the central government have played an important role in this increase, as our analysis shows they paid 27% more than other bidders for an otherwise equivalent land parcel.

8/05/2012 On May 3, Gengtian Zhang, Director of Research at the Urban China Initiative (UCI), gave a lecture on how to promote healthy urbanization for the National Development and Reform Commission (NDRC) in Sichuan Province. Most of the 100 delegates at the talk were urban planning and policy directors and professionals, mainly from the NDRC offices for Sichuan Province, Kuoquan County, and individual cities in Sichuan. Zhang's lecture described the direction and focus of urbanization development inChina, including some research results from an international perspective, and proposed how to promote healthy urban development in China's cities. The lecture focused on six main ideas critical to China's continuing urbanization, including promoting a healthy model of urban development, improving the quality of urban planning, promoting the welfare of migrant workers and their integration into urban areas, improving China's city layouts, advancing urban agglomeration and megaregion development, and improving urbanization policies and regulations. Zhang opened by discussing the significance of promoting the urbanization process from the perspective of expanding domestic demand and enhancing economic and social development. He also described the main findings of UCI's recent report, "The 2011 Urban Sustainability Index", particularly relating to its implications for sustainable development. He stressed that we should regard migrant worker integration into cities as most important task in the next phase of China's urbanization. In regards to urban layout and physical planning, he described the future Functional Area Plan for Chinese cities, including the "two horizontal and three vertical" urbanization strategy pattern (to make Lianyungang-Urumqi channel and Yangtze channel two horizontal axis, and make coastal line, Haerbin-Beijing-Guangzhou channel and Baotou-Kunming channel three vertical axis of Urbanization zoning strategy

Zacharias, John (2012) Resisting motorization in Guangzhou. Habitat International, 36 (1). pp. 93-100. Private motorization has accompanied unprecedented urbanization in China, as a matter of public policy. Planning at the provincial and city levels has supported the rapid build-up of the private car fleet in major cities through the development of regional and urban highway networks, higher capacity local streets and much higher standards for car parking in new developments. By contrast, urban planning until 1994 concentrated on the building of community and the support for a non-motorized lifestyle. Guangzhou experienced particularly rapid city-building during this period because it was at the centre of the market reforms launched in 1978. The communities that were built form a broad ring around the historic core of the city, constituting one of the most significant obstacles to government ambitions to maintain the recent growth rates in car ownership. Guangyuan and Jiangnanxi are examples of such middle-class, home-owning communities where daily life remains almost exclusively non-motorized. Self-organized groups in the community are increasingly vocal and active in their demands to enhance local environmental quality and restrict local motorization. Local municipal authorities, although increasingly active and autonomous, try to strike a balance between government objectives and local demands. The application of motorization illustrates the growing gap between high-level policy and grassroots urban planning in Guangzhou.

In common with other major economic centres in China, Shanghai's energy consumption has been increasing rapidly to support the high growth rate of its economy. To achieve rational, efficient and clean use of energy, together with improved environmental quality within the city, the Shanghai municipal government has decided to expand the supply and utilization of natural gas. Shanghai plans to increase the share of natural gas in its primary energy mix to 7 per cent by 2010, up from 3 per cent in 2005. This increase in natural gas demand has to be matched with a corresponding increase in supply. To date, the Shanghai region has relied on offshore extracted natural gas but this supply is limited due to the size of the reserves. Since 2005, the West-East pipeline has provided an alternative for Shanghai but demands from other regions could reduce the potential for expanding supplies from that source. Since domestic production will not be sufficient to meet demand in the near future, Shanghai is building a liquefied natural gas (LNG) regasification terminal at the Yangshan deep-water port that would allow an additional supply of more than 3 billion cubic meters per year of natural gas. Malaysia has already committed to supply LNG to the Shanghai terminal at a price that is significantly higher than the wholesale "city-gate" price for natural gas transported via pipeline, but still lower than the gas price to end-use consumers. The presence of both an LNG terminal and a transmission pipeline that connects Shanghai to domestic gas-producing regions will create gas-on-gas competition. This study assesses the benefits of introducing such competition to one of China's most advanced cities under various scenarios for demand growth. In this paper, the impact of imported LNG on market concentration in Shanghai's gas market will be analysed using the Herfindahl-Hirschmann index (HHI) and the residual supply index (RSI). Our results show that Shanghai remains a supply-constrained

Full Text available. As some of the most rapidly urbanizing places in the world, China's cities have a unique relationship with global climate change. The economies found in Chinese cities are extremely resource and energy intensive; as a result, they produce significant levels of greenhouse gas (GHG) emissions. This article provides comprehensive and detailed emissions inventories for Shanghai, Beijing, and Tianjin, which were found to be responsible for 12.8, 10.7, and 11.9 tonnes of carbon dioxide equivalent per capita (t CO2-eq/capita), respectively, in 2006. The majority of emissions were from electricity production, heating and industrial fuel use, and ground transportation. The prevalence of coal in the energy supply mix (including up to 98% in Tianjin) was a fundamental cause of high energy emissions. Non-energy emissions from industrial processes were also significant, including emissions from cement and steel production. The GHG inventories for Shanghai, Beijing, and Tianjin point to sectors requiring the most attention in terms of low-carbon growth. Compared to ten other global cities, Chinese cities are among the highest per capita emitters, alluding to the important challenge China faces of reducing emissions while improving the quality of life for urban residents. Accordingly, this article concludes with a discussion of the opportunities and issues concerning low-carbon growth in China, including the potential for renewable energy and the difficulties associated with emissions relocation and policy adoption.

Summary China has seen the largest human migration in history, and the country's rapid urbanisation has important consequences for public health. A provincial analysis of its urbanisation trends shows shifting and accelerating rural-to-urban migration across the country and accompanying rapid increases in city size and population. The growing disease burden in urban areas attributable to nutrition and lifestyle choices is a major public health challenge, as are troubling disparities in health-care access, vaccination coverage, and accidents and injuries in China's rural-to-urban migrant population. Urban environmental quality, including air and water pollution, contributes to disease both in urban and in rural areas, and traffic-related accidents pose a major public health threat as the country becomes increasingly motorised. To address the health challenges and maximise the benefits that accompany this rapid urbanisation, innovative health policies focused on the needs of migrants and research that could close knowledge gaps on urban population exposures are needed.

Abstract Taking Beijing as a case study, this paper analyses new trends in peri-urbanisation and the city's planning responses after 2000 in China. The results of the analysis show that the percentage of temporary migrant residents continues to grow in the peri-urban region and the social inequalities in relation to quality of life between local people and migrants have increased there. In particular, there is a concentration of thousands of young and well-educated migrants in the peri-urban region, resulting in a new kind of urban slum. Sprawling development still dominates Beijing's fringe. New planning policies related to an urban-rural integration strategy have played a positive role in improving living conditions in rural areas and reducing the social and economic gaps between urban and rural areas in the peri-urban region. However, planning in the peri-urban region is still facing new challenges due to vertically and horizontally fragmented management, growing market forces, and social discrimination caused by the remnants of the hukou mechanism. This suggests that it will not be easy to achieve the planning goal of urban-rural integration and harmony society unless further actions are taken to enhance political capacity of planning system in Beijing. The capacity-building of planning should be facilitated if institutional innovations can be made in arrangements of power, rights, public resources, accountability, and legitimacy in the planning system. Highlights ► Many new trends in peri-urbanisation have appeared after 2000 in Beijing. ► Peri-urbanisation contributes to growth in social inequalities. ► It will not be easy to achieve the planning goal of urban-rural integration. ► New urban-rural integration policies are facing challenges. ► The institutional capacity of planning needs to be reinforced.
