  1. NSFC Project (No.70933005) Climate Risk and Resilient City:Challenge and Awareness in China PAN Jihua, ZHENG Yan, XIE Xinlu, ZHOU Yamin, WANG Jianwu, ZHU Shouxian, et al. December 2nd 2011, Durban, South Africa Institute of Urban & Environmental Studies (IUE), Chinese Academy of Social Sciences (CASS)

  2. Contents • Climate risks and challenges for adaptation in China • Challenges for building resilient cities • Make city more resilient and low carbon: Integrate adaptation and mitigation into urban strategy

  3. Climate Risks in China & Challenges for adaptation

  4. Economic Losses of GDP in total Weather related disasters in China (1990-2010) Economic Losses of GDP in different weather disasters in China (2003-2010)

  5. Climate Vulnerability Mapping for China (2005-2010)

  6. The top 3 most Vulnerable provinces were Gansu, Ningxia and Guizhou, which is consistent with the climate capacity discrepancy. The West regions are more vulnerable than the coastal and East regions in China, since the former ones were more sensitive to climate hazards and socially vulnerable. CHALLENGES: Geographical unbalance in climate risks and vulnerability Increasing wealth and more exposed physical capitals: esp in coastal developed areas Aging society with more exposure population Preliminary findings:

  7. Challenges for building resilient cities

  8. Fast Urbanization in China since 1980s Shanghai, Tianjin, Guangzhou, Ningbo, Hongkong, …ranking among top 20 coastal cities with high climate risk by 2050 (OECD,2008）

  9. Vulnerable mega-cities in China

  10. Vulnerability measurement for mega-cities in China Chongqing ranked in the top one vulnerable city among the 4 municipalities, cause its more vulnerable population rate, higher climate sensitivity and environmental disasters.

  11. Weakness & Strengths of China’s Mega-cities Financial capacity Technical capacity Engineering infrastructures Institutional capacity Ecological health Mainstreaming Adaptation and DRR into Urban planning Challenges: More aging and wealthier cities in future Disparity in economic and social vulnerability Consolidating Urbanization with large poverty population Challenges for building resilient cities

  12. Make city more resilient and low carbon

  13. 46.6% 6.22亿人 URBANIZATION IN CHINA 12th FYP: 47.5%51.5%，annual avg rate 0.8%= 12 million urban population

  14. 1790-2050 USA urbanization China facing more challenges than that of developed countries 1920-1960年 年均提高0.47个百分点

  15. Make city more resilient and low carbon: Integrate adaptation and mitigation into city strategy • Adaptation • Reduce the vulnerability: lifeline of city • Low carbon adaptation: urban green lands, green power, environmental infrastructures, etc. • Synergy between mitigation and adaptation • Planning • Urban planning: transport, residential settlement • Industry planning: resources dependant sectors • Spatial planning: population and land using • Technology • Green building, smart grid, etc • Adaptive technologies • Management and governance
