The synergy/trade-offs between strategies of mitigating and adapting to climate change have been highlighted by the IPCC assessment reports. Despite awareness of green infrastructure (GI) for mitigating and adapting to climate change, attempts to use a systems approach for assessing their synergies and trade-offs remains limited. This study developed an ecological–economic model of the Taipei Metropolitan area. Changes of effects on climate change adaptation and mitigation provided by GI are simulated for assessing the overall climate change impacts of different GI strategies. We established a framework to analyze the temporal variation of the climate benefits of GI concerning the changes in carbon storage, accumulated runoff, and carbon dioxide emissions due to land use change. The results show that almost all GI strategies have synergies with mitigating and adapting to climate change. Implementing urban growth management strategies to preserve the integrity of GI is the most effective way to maximize synergies in a developing city. Although GI strategies can create synergistic effect, internal trade-offs can also emerge alongside synergies. Using a systems approach to simulate alternative climate strategies allows for joint consideration of mitigation and adaptation and to enhance synergies and eliminate trade-offs of urban climate policies.

探索台北城市绿色基础设施战略的协同/权衡 - 一种系统性方法


IPCC 评估报告强调了缓解和适应气候变化战略之间的协同/权衡。尽管人们意识到绿色基础设施 （GI） 可以缓解和适应气候变化，但使用系统方法来评估其协同作用和权衡的尝试仍然有限。本研究开发了台北都会区的生态经济模型。模拟 GI 对气候变化适应和减缓的影响变化，以评估不同 GI 策略对气候变化的整体影响。我们建立了一个框架来分析 GI 的气候效益在土地利用变化引起的碳储存、累积径流和二氧化碳排放变化方面的时间变化。结果表明，几乎所有的 GI 策略都与减缓和适应气候变化具有协同作用。实施城市增长管理战略以保持地理标志的完整性，是在发展中城市中最大限度地发挥协同效应的最有效方式。尽管 GI 策略可以产生协同效应，但内部权衡也可能与协同效应一起出现。使用系统方法来模拟替代气候策略，可以共同考虑缓解和适应，并增强协同作用并消除城市气候政策的权衡。
