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.

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.

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.

[ScienceDirect, via Biblio-SHS] Auteur : Steffen Lehmann Paru dans : Habitat International, Available online 4 January 2012 Abstract The purpose of this paper is to explore the rapid urbanization of Chinese cities with a focus on the plans for a new, ongoing urban sub-centre in the north-west of Shanghai: Zhenru Urban Sub-Centre. Information-rich urbanization is a defining feature of the 21st century, reshaping cities and communities in China and in developing countries around the world. The scale and pace of change requires a solid systems approach of urban development. In 2011, China announced that it has reached an urbanization rate of 50%. If we take rapid urbanization 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 industrialized nations, i.e. driving urban growth with high consumption patterns without fully considering the environmental and social needs and occupants' behaviour and aspirations. This 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 decentralization seem to have replaced the 'machine' metaphor which was based on efficiency based on the availability of cheap fossil fuels. 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 cur

Development zones are the important carriers of China's promoting industrialization and attracting international investment in the past 30 years and act as the primary means of city expansion. In this article, we analyse the low efficiency of land use problem existing in China's current development zones. Comparing with the general old city update phenomenon, we make a detailed illustration on the feasibility and comparative advantage of redevelopment of development zones. On this basis, combining with the investigation practice, we propose the basic redevelopment models of development zones and analyse the typical redevelopment cases of development zones in Xi'an, Shanghai, Changzhou, Hangzhou and Nanjing.
