[ScienceDirect, via Biblio-SHS] Auteur : XiaoFang Sun, TianXiangYue, ZeMeng Fan Paru dans : Procedia Environmental Sciences, Volume 13, 2012, Pages 590-597 18th Biennial ISEM Conference on Ecological Modelling for Global Change and Coupled Human and Natural System Abstract Land use changes affect many aspects of Earth System functioning, for example in impacting global carbon cycle, contributing to climate change, or increasing soil erosion. 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

DOI : http://dx.doi.org.gate3.inist.fr/10.1016/j.proenv.2012.01.113 [ScienceDirect, via Biblio-SHS] Auteur : Gengyuan Liu, Zhifeng Yang, Bin Chen, Meirong Su (State Key Joint Laboratory of Environmental Simulation and Pollution Control, School of Environment, Beijing Normal University, Beijing) Paru dans : Procedia Environmental Sciences, Volume 13, 2012, Pages 1189-1203, 18th Biennial ISEM Conference on Ecological Modelling for Global Change and Coupled Human and Natural System Abstract In this paper, a dynamic low-carbon model was developed to show a quantitative and consistent future snapshot. This study presents three scenarios for Chongqing's energy consumption and related CO2 emissions up to 2020, which includes basic development scenario, macro-policy control development scenario and low carbon development scenario. It explains the crucial technologies for Chongqing city as it leaves a business-as-usual trajectory and embarks on a low carbon pathway. A major finding from the scenario analysis is that low carbon and energy-saving policies can dramatically improve Chongqing's position. Under the low carbon scenario, several suggestions for policy making are proposed. This dynamic low-carbon model would benefit from the allocation of decision-making powers in the areas of regulation, policy-making and planning for low carbon development.

Siu Yu Lau, Stephen Gonzalez Martinez Paula In: ACE©, AÑO 7 núm.20, OCTUBRE 2012 China is going through one of the most dramatic social and cultural transformations in its history. In this speed change scenario, the never - questioned conventions in the western architecture have been betrayed. Invention, reinterpretation sometimes even revolution, never represent a step further as they did in the XXI century theoretical thinking. To engage architectural thoughts with the booming economy could contribute to the definition of a contemporary Chinese architecture, far from the generic city, in a society that has evolved from pre-modernism to post-industrialism in a short period of time. Through the analysis of Hong Kong, and a series of case studies, a conclusion to this scenario is sought.

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

unded under the European Commission's Seventh Framework Programme, URBACHINA is a collaborative project managed by a consortium of 11 leading Chinese and European research institutions. Coordinated by CNRS (France's National Centre for Scientific Research), URBACHINA will analyse China's urbanisation trends for the next 40 years and define possible future scenarios with reference to concepts of sustainability. European Union - China cooperation URBACHINA is a research project, which places strong emphasis on the cooperation between the EU-China. Although Europe and China have followed different urbanisation paths, there is nonetheless room for mutual learning. One of the main objectives of this project is to strengthen the collaboration between Chinese and EU researchers and policy-makers driven by the common goal of building sustainable cities.
