Abstract

Ensuring the sustainability and resilience of urban infrastructure systems in the face of climate change impacts is of paramount importance. This chapter emphasizes the integration of climate change considerations into decision-making processes for urban development. It introduces the concept of green-blue-gray infrastructure (GBGI), which combines three types of infrastructure to provide a comprehensive solution for adapting to and mitigating climate change impacts. The chapter highlights the numerous benefits of green infrastructure (GI), which has emerged as a sustainable urban system surpassing traditional gray infrastructure. GI has proven effective in regulating temperature, reducing energy consumption, improving air quality, managing floods, and enhancing drought resilience. However, the chapter also acknowledges the need for further research on the role of GI in flood management and calls for the application of theoretical frameworks in GI research. Additionally, the chapter discusses gray infrastructure (GRAI), which encompasses conventional infrastructures such as pipelines, roads, and bridges that have historically shaped urban development. However, GRAIs contribute to the proliferation of impermeable surfaces, impeding rainwater infiltration and leading to flooding and other environmental challenges. The chapter underscores the importance of integrating green and blue infrastructure elements into the existing gray infrastructure systems to optimize flood risk management and enhance urban resilience.
