Analysis of Nature-Based Solutions (NbS) Design Methods at Azabudai Hills : Focusing on the Relationship between Green Infrastructure Design Methods and NbS Global Criteria by IUCN

Purpose: In this study, we will examine the ecological green infrastructure among the nature-based design methods appearing in Azabudai Hills, and examine the application examples of each element and the results of resolving environmental and social issues according to the nature-based solution standards. Method: First, we conducted basic research on the definition and outline of the nature-based solution (NbS) design method, and examined the contents of the eight standards and 28 detailed indicators of the IUCN that implicitly summarized it. Based on this, we established the framework and scope of analysis for analyzing the nature-based solution design method applied to Azabudai Hills. Lastly, the green infrastructure design methods,especially focused on green space applied to Azabudai Hills, green network design methods, and others were analyzed, and based on this, the relationship between each design method and the solution to social crisis and the consistency with the nature-based solution standards were comprehensively organized. Result: Azabudai Hills has created a large-scale green space of approximately 24,000m² and through planting plans centered on approximately 320 native species, it is characterized by a biodiversity conservation design method that not only restores and preserves the natural ecosystem and secures biodiversity, but also responds to climate issues such as reducing the urban heat island phenomenon. In addition, it is expanding the scope of application of nature-based solutions by building a green network that connects green spaces not only inside but also outside the complex.
