Given the increasing environmental challenges due to urbanization and climate change, blue-green infrastructure (BGI) presents a sustainable solution for urban resilience, focusing on urban heat island (UHI) effects, urban flooding, and water quality improvement. BGI concepts remain underexplored due to the lack of universally established guidelines for their implementation. Thus, a review of the functions of BGI in global and Korean applications was conducted, resulting in the development of a framework for BGI implementation. The developed framework potentially offers step-by-step guidance for urban planners, policymakers, and researchers. The process begins with identifying the primary environmental problem that the BGI technology will address, followed by evaluating site characteristics and selecting the appropriate BGI type. A detailed design and model are then developed, with simulations conducted to assess the impacts and effectiveness of the BGI. If the simulation results are positive, approval from relevant institutions is sought, leading to construction. If necessary, the design is retrofitted to meet the required standards. Post-construction monitoring, maintenance, and continuous improvements are essential for ensuring the longevity of the BGI system. Additionally, the paper identifies key barriers to BGI adoption, including institutional, technical, and socio-cultural challenges, and proposes improvement measures applicable to Korean cities. By addressing such barriers, the integration of BGI can be enhanced, fostering climate resilience and improving urban livability in the face of climate change.
Abstract
