Presentation Title: Shared Learning Across Coast Cities: Impacts, Vulnerability and Socio-Ecological Responses

 

Summary

Urban growth is a complicated process involving the spatial-temporal changes of all socio-economic and physical components at different scales. Usually, urban growth is dependent on socio-economic variables and spatial variables. Urban growth also can respond to climate change by adapting to its impacts and reducing vulnerability related to climate change in the short- and long-term. Responding to climate change involves an iterative risk management process that includes both adaptation and mitigation, which can provide a wide variety of policies and countermeasures from the government, and patterns of urban growth in response to climate change.

The impact of climate change on urban infrastructure was the focus of this research. Using Shanghai, China as a case study, the eco-vulnerability assessment, urban infrastructure distribution and strategies for urban sustainability were explored.

Key Lessons Learned

  • In comparison to the cities in this study, Shanghai ranks third highest in terms of environmental challenges.
     
  • The Shanghai average temperature has risen over the last 15 years. The rate of change is higher than the national average rate of change.
     
  • The urban heat island in Shanghai is increasing per year and precipitation has become more irregular.
     
  • Sea level rise increases are found in the China East Sea, higher than other estuary areas in China.
     
  • Tropical cyclones are increasing in intensity and becoming more frequent (the highest in 100 years).

Policy/Practice Implications of Research

  • Master planning that includes eco-network planning incorporating greenways and walkways is important for adaptive capacity to climate change.
     
  • Planning must integrate the water supply system, power and gas system, and communications system.
     
  • Strategies for urban infrastructure including flood control construction have given priority investment to the city-center area, but upstream and rural areas must also be included.

Knowledge Gaps and Needs

This framework could be applied to other estuary cities, in order to enhance urban green infrastructure development and the coordination of urban growth and environmental protection to reduce climate change impacts.
