Potential Impacts of Climate Change in Rapidly Urbanizing Regions – A Case Study in Hangzhou (China) Region

Abstract

Climate change is expected to be a major driving force of landscape in the coming decades. It will have a multitude of potential impacts that vary in intensity and effect according to region and sector. In the context of global warming, the climate of China has changed significantly in the recent 100 years. According to "China's National Climate Changes Programme", there are mainly five aspects about the fact of climate changes in China: firstly, the annual average temperature increases; secondly, regional precipitations fluctuate considerably; thirdly, the frequency of extreme weather events increases in speed and intensity; fourthly, sea level rises; and fifthly, mountain glaciers retreat rapidly, with the trend accelerating. The reason for climate change in China caused by human activities is mainly irrational land use, which chiefly results from rapid industrialization and urbanization. This paper explores the potential impacts of climate change for the Hangzhou region. The aim is to conclude, on the one hand, some of Hangzhou’s sensitivities in relation to the expected primary effects of climate change, and on the other hand, to reflect on methodology to formulate preconditions as a scientific basis for further research by design on integrated adaptation options for future spatial developments to upgrade Hangzhou’s resilience in relation to climate change challenges.
