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

The simulation of land use change is important in environmental impact assessment and land use planning. We assessed the land use scenarios of China in the next 100 years based on the SMLC (surface modelling of land cover change) model and Dyna-CLUE (dynamic conversion of land use and its effects) model. Three SRES scenarios were evaluated: Global Economy (A1FI): lean government, strong globalization; Continental Markets (A2a): lean government, regional culture and economic development; Regional communities (B2a): much government intervention, regional cultural and economic development. Ten land cover types were simulated, which are cultivated land, woodland, grassland, built-up land, water area, wetland, nival area, desert, bare rock and desertification land. The SMLC model was used to calculate changes in area for each land use types in the future at country level while the spatially explicit land use model Dyna-CLUE was used to simulate land use pattern at 2 km2 resolution based on the country level areas demands for each land cover type. The results show that the cultivated land would decrease in all of the three scenarios, while in the A2a scenario, the cultivated land would decrease with the lowest rate because of the high population growth, high level of market protection and low agricultural efficiency; in the B2a scenario, it would decrease with the highest rate caused by the decreased population numbers and increased crop productivity. The nival area would decrease with the highest rate in the A1FI

Thématique n° 2 [ScienceDirect, via Biblio-SHS] Auteur : Hui Wang, Lanlan Wang, Fubing Su, Ran Tao Paru dans : Habitat International, Volume 36, Issue 2, April 2012, Pages 201-209 Abstract Rural residential land represents one of the most important land use types in China. However, the literature so far has paid insufficient attention to the patterns and efficiencies of this type of land use. To fill in this gap, this paper uses a national survey to analyze the institutional setups for rural residential land use, to assess the effectiveness of existing regulations, and to evaluate the efficiencies in rural residential land use. Farmers' subjective receptiveness toward rural residential property regulation reform is also investigated. We find that rural residential properties are inefficiently utilized under the existing land use regulations, that those who are younger and who had previous migration experiences are more likely to support the free trading of rural residential properties while the village cadres are more likely to oppose it. A coordinated policy reform package that includes free trading of rural residential properties and Household Registration System to facilitate permanent migration out of the countryside is proposed to address the existing efficiencies in China's rural residential land use. Highlights ► Rural residential land is an important land use type in China. ► Under existing regulations rural residential land is inefficiently used. ► A coordinated land-Hukou reform package is needed to address the inefficiency.

DOI : http://dx.doi.org.gate3.inist.fr/10.1016/j.apgeog.2011.11.006 [ScienceDirect, via Biblio-SHS] Auteur : Kai-ya Wu, Hao Zhang Paru dans : Applied Geography, Volume 34, May 2012, Pages 137-145 Abstract In this study, Hangzhou, the capital city of Zhejiang Province in eastern China was selected as a case study. Based on time series Landsat MSS/TM/ETM + imagery and historical census data, analysis of the relationship between land use dynamics, built-up land expansion patterns, and underlying driving forces from 1978 to 2008 was performed, using an integrated approach of remote sensing (RS) and geographic information system (GIS) techniques and statistical methods. The results showed that rapid expansion of built-up land in the Hangzhou Metropolitan Area (HMA) led to accelerated land use conversion. The built-up land increased from 319.3 km2 in 1978 to 862.5 km2 in 2008. Expansion patterns of built-up land in the HMA were essentially characterized by axial expansion centered on the former city proper before 1991. In 1996 and 2001, two significant administrative division adjustments for the former city proper and two neighboring municipalities occurred. This led to the success in implementing strategies of "frog-leaping development along the Qiantang River" and "crossing the Qiantang River and developing southward". Spatially, a closer linkage between the former city proper and two neighboring municipalities was established. Consequently, rapid development of infrastructures, facilities, intensive industrial parks, and urban and rural settlements along the Qiantang River resulted in the eastward and southward expansion of built-up land. Thus, from 1991 to 2008 the model of urban expansion resulted in a multi-nuclei pattern. Furthermore, as shown with detailed analysis, the growth pattern of built-up land of the HMA is highly correlated with socio-economic factors, including the gross domestic product (GDP), per capita disposable income, popul

Thématique n° 2 [ScienceDirect, via Biblio-SHS] Auteur : Lynn Price, Nan Zhou, David Fridleya, Stephanie Ohshitaa, Hongyou Lua,Nina Zhenga, Cecilia Fino-Chen Paru dans : Habitat International, Available online 28 January 2012 Abstract In 2009, China committed to reducing its carbon dioxide intensity (CO2/unit of gross domestic product, GDP) by 40-45% by 2020 from a s2005 baseline and in March 2011, China's 12th Five-Year Plan established a carbon intensity reduction goal of 17% between 2011 and 2015. The National Development and Reform Commission (NDRC) of China then established a Low Carbon City policy and announced the selection of 5 provinces and 8 cities to pilot the low carbon development work. How to determine if a city or province is "low carbon" has not been defined by the Chinese government. Macro-level indicators of low carbon development, such as energy use or CO2 emissions per unit of GDP or per capita may be too aggregated to be meaningful measurements of whether a city or province is truly "low carbon". Instead, indicators based on energy end-use sectors (industry, residential, commercial, transport, electric power) offer a better approach for defining "low carbon" and for taking action to reduce energy-related carbon emissions. This report presents and tests a methodology for the development of a low carbon indicator system at the provincial and city level, providing initial results for an end-use low carbon indicator system, based on data available at the provincial and municipal levels. The report begins with a discussion of macro-level indicators that are typically used for inter-city, regional, or inter-country comparisons. It then turns to a discussion of the methodology used to develop a more robust low carbon indicator for China. The report presents the results of this indicator with examples for 6 selected provinces and cities in China (Beijing, Shanghai, Shanxi, Shandong, Guangdong, and Hubei). The repor

Energy, monetary and human time variables as well as information on environmental pressures, have been combined to compare different typologies of households and the metabolism of different patterns of land use from an integrated perspective. The results show that urbanization strategies, aimed at shifting the current land use and at displacing the local population, while increasing the economic efficiency is also associated with an increase in fossil energy consumption and environmental pressure, as well as a reduction of the multifunctional characteristic of the area under investigation. Based on these findings the paper also offers a critical discussion of the Chinese rural development policy arguing that the multifunctionality of rural areas should be taken into account by Chinese policy-makers and planners as a viable strategy to achieve rural development targets. Highlights ► Urbanization strategies in China drive the land use change of rural areas. ► Forced migration decreases rural food self-sufficiency and diversification of risk. ► HEPA patterns have higher economic efficiency and energy intensity than LEPA. ► Rural-urban migrations favor the creation of mono-functional agricultural systems.

Xuefei Ren's work on the high-end of the building boom in China brings together the sociology of globalization with the study of architecture and the built environment. Building Globalization treats architectural production as crucial to the material and symbolic ways in which global cities are made. Based on Ren's doctoral research at the University of Chicago, the book draws on fieldwork conducted in Beijing and Shanghai between 2004 and 2008, covering the bull years leading up to the Beijing Olympics. China is now taken to exemplify the geo-demographic shift that has seen developing countries lead current processes of urbanisation. However the Chinese government's attitude towards quanqiuhua chengshi (global cities) and its support for rapid urban growth from the mid-late 1990s represented a striking reversal of official policy which had been to limit the growth of large cities and promote instead the development of small-medium centres (p.11). The re-scaling of state power to metropolitan level in the interests of enhancing urban competitiveness has been an international trend in recent decades. In China this has proved particularly effective in driving urban growth, given state ownership of land and government control over household registration, urban planning and development decisions. Metropolitan governments in China have the kind of ownership and discretionary powers of which the most boosterist western city mayors can only dream. Ren argues convincingly that the processes shaping these cities are increasingly transnational; in particular, the forces that make buildings 'operate beyond national boundaries, as seen in the circulation of investment capital, the movements of built-environment professionals, and the diffusion of new technologies' (p.6). However, while Chinese economic growth may have destabilized a global balance of power dominated by the triad of the USA, the European Union and Japan, Ren's analysis suggests that older core-peripher

[ScienceDirect, via Biblio-SHS] Auteur : Nesru H. Koroso, Paul van der Molen, Arbind. M. Tuladhar, Jaap A. Zevenbergen Paru dans : Land Use Policy, Volume 30, Issue 1, January 2013, Pages 417-426 Abstract This research investigates whether the process of transfers of urban land Use rights in China, particularly where the state plays a major role in the transfer of urban land, complies with basic principles of good governance. In order to assess market, an assessment framework is developed. A critical analysis of secondary data from official and non-official sources is done. Major changes since late 1980s in the institutional environment and subsequent results have been assessed. The findings reveal that the transfer of urban land Use rights in China is gradually responding to an improved governance system. Institutional reforms have led to a steady improvement in indicators such as transparency, efficiency, and access to information. Nonetheless, the market has significant weaknesses in addressing equity issues, engaging stakeholders, tackling corruption and dealing with expropriations. In general, the paper finds that the efficiency and effectiveness of the urban land market largely depends not on the type of tenure regime per sé, but rather on the system of governance in place. Highlights ► Based on existing data sources, this paper analyses the performance of the market for urban land Use rights in China. ► The assessment framework is based on governance principles like equity, participation, access to information, efficiency, and transparency. ► The result is that the market needs improvements regarding governance principles. ► However, a positive impact of the efforts of the government to improve can be observed.

Changes in sexual attitudes and behaviors and resurgence of the sex industry in China have increased concerns about HIV/AIDS and sexually transmitted infections (STI) epidemics. Little attention has been paid to the significant and growing sex industry in rural China. Promotion of barrier protection in this context is most effective to prevent STIs and pregnancy. The female condom (FC) is a barrier method that gives women more autonomy in its application, and has other advantages, but has been little promoted and tested in high risk contexts in China. The China/US Women's Health Project was designed to promote FC use in addition to male condoms (MC) through outreach intervention conducted in sex work establishments in rural and small urban towns in southern China, using the original prototype FC1. The study used quantitative and qualitative methods to document the pre-intervention context, intervention delivery process, and post-intervention outcomes of FC use. In this paper we compare post-intervention FC users and non-users in the first study sites, two rural towns in a single county in Hainan Province. Examination of cross-sectional six-month and 12-month surveys indicated that, despite relatively high MC use, about one-third of the women in sex work establishments in these rural towns had adopted FC at each post-intervention survey. Compared with non-users, FC users were more likely to be freelance women in boarding houses, more sexually experienced, married with children, more sexually active in the prior month, and more exposed to the intervention. The rural context hampered intervention implementation, particularly the significant limits in health and human resources available to manage prevention of HIV/STIs among women in the sex industry. These challenges highlight the need to better understand the context of the rural sex industry and capacity of local resources for better prevention efforts and the benefits that new prevention technologies like FC can of

[ScienceDirect, via Biblio-SHS] Auteur : Wilco Chan Paru dans : International Journal of Hospitality Management, Volume 31, Issue 4, December 2012, Pages 1130-1142 Abstract Achieving effective and objective energy benchmarking for hotels is integral in fostering the sustainable development of the lodging sector. In this work, we reveal the major and minor streams of hotel energy benchmarking and ascertain that the most popular approach in benchmarking is normalized energy use intensity (EUI) based on floor level. Previous efforts to establish EUI indicators using subsystem average, data envelopment analysis (DEA), and regression technique are also studied. We propose that hotel energy benchmarking based on floor area is useful from the top-down management perspective. However, on a practical perspective, energy benchmarking based on facilities should be the first priority for hotel management or owners. Compared with the general energy benchmarking in the building sector, we find that the hotel sector lags behind in the adoption of computer modeling for benchmarking. By conducting in-depth interviews with hotel engineers, system designers, and professors to identify the challenges faced by current hotel energy benchmarking, we gain deeper insights on the development of hotel energy benchmarking that reflect the current situation in China. A taxonomical approach focusing on four directions of hotel energy benchmarking is thus proposed. By coordinating with various types of stakeholders and implementing the proposed development plan, the local Construction Ministry, Tourism Bureau, and Energy Improvement Office can realize this conceptual hotel energy benchmarking in China.

Chen, Yiu Por. (2012). Land Use Rights, Market Transition, and Rural-urban Labor Migration in China (1980-84). UC Los Angeles: The Institute for Research on Labor and Employment. Online at: http://escholarship.org/uc/item/3pk220mn# This paper provides a systematic analysis of the way shifts in property utilization rights in China induced another sequence of institutional changes that led to the rise of rural-urban labor migration from 1980 to 1984, a critical period in the country's market transition. I show that the 1980s' HoUsehold Responsibility System (HRS), which brought family farming back from the communal system, endowed rural hoUseholds not only with land Use rights, but also with de facto labor allocation rights. These shifts in property relationspromoted a growth in agricultural market size as well as the emergence of intraprovincial non-hukou rural-urban migration, which may have made labor retention policies such as the small township strategy ineffective, and may have given the government an incentive to deregulate its subsequent labor market policy.

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

Abstract In 2011, China announced that it has reached an urbanisation rate of 50%. If we take rapid urbanisation as a given and that it is already well underway, it is still widely unclear what research needs to be conducted and policy changes made to support municipalities of fast transforming cities and to avoid repeating the development mistakes that have occurred in industrialised nations, i.e. driving urban growth with high consumption patterns without fully considering the environmental and social needs and occupants' behaviour and aspirations. The scale and pace of change requires a solid systems approach of urban development. The purpose of this paper is to explore the rapid urbanisation of Chinese cities with a focus on the plans for a new, on-going urban sub-centre in the north-west of Shanghai: Zhenru urban sub-centre. Information-rich urbanisation is a defining feature of the 21st century, reshaping cities and communities in China and in developing countries around the world. The paper compares two cases of urban development patterns for new sub-centres for polycentric city structures: it relates to new urban sub-centres in Berlin (Germany) and Shanghai (China), and the relationship of these sub-centres to 'Network City' theory. Network theory is useful in this context as the 'network' metaphor and concepts of decentralisation seem to have replaced the 'machine' metaphor which was based on efficiency based on the availability of cheap fossil fuels. The question to be addressed is how Chinese cities can be better steered towards more sustainable models of development. As cities aim to move towards more resilient urban ecosystems and polycentric systems, the case of Potsdamer Platz Berlin, compared to Zhenru sub-centre in Shanghai, is discussed. Both are transport-oriented developments promoting mixed-use density and less car-dependency. According to documentation of the Shanghai municipality, Zhenru urban centre, which is currently
