Urban areas are at particularly high risk from the impacts of climate change and extreme weather events due to the spatial concentration of people and economic activities. To understand better the climate benefits and co-benefits provided by green infrastructure in response to climate change in the Taipei Metropolitan Area, this study reviews the concepts of synergy, trade-offs and cobenefits in the literature related to green infrastructure, and also collects and organizes the existing research on the climate benefits of green infrastructure in Taiwan. The changes in green infrastructure from 1981 to 2015 are analyzed. An expert questionnaire is adopted to identify the synergies, tradeoffs and co-benefits of the Taipei Metropolitan Area’s green infrastructure in response to climate change. Analytical results show hat green infrastructure covered around 81.12% of the territory of the Taipei Metropolitan Area in 1981 and has since slightly decreased to a coverage of 78.22% in 2015. However, the total area of green infrastructure decreased by more than 10% in the highly urbanized core areas within the Taipei Metropolitan Area. The questionnaire results indicate that“runoff reduction due to interception and infiltration effects”is the most important benefit arising from the regulation of climate change through the installation of green infrastructure in the Taipei Metropolitan Area. The co-benefits of green infrastructure in addressing climate change given the effects on cultural services are greater than other categories of ecosystem services. Besides“runoff reduction due to interception and infiltration effects”, the main additional climate benefits provided by green infrastructure in the Taipei Metropolitan Area are synergy effects, which“provide habitat for native species”and enhance“aesthetics and quality of life.”The research suggests that governments should emphasize the co-benefits of those climate actions and make them evident in the daily lives of citizens to increase support for government action on climate change, thus enabling governments to perform climate mitigation and adaptation agendas while achieving other significant objectives. |
