都市洪水管理におけるNBSやグリーンインフラの類型論的限界を指摘し、機能・運用に基づく新たな解釈枠組みを提案。ロッテルダム、東京、コペンハーゲン、シンガポールの4事例を比較し、グレー・グリーン・ブルーインフラの機能的結合が重要であることを示した。特にブルーインフラがシステム全体の緩衝機能を担うと結論。
English
This study critiques typological approaches to Nature-Based Solutions and Green Infrastructure, proposing a functional-operational framework for urban flood mitigation. Comparing four international cases (Rotterdam, Tokyo, Copenhagen, Singapore), it finds that effectiveness depends on functional coupling of grey, green, and blue infrastructures, with blue infrastructure serving as a systemic buffer. The framework aids planners in implementing integrated ecological infrastructures.

日本のGX文脈において
日本では気候変動適応策として都市洪水対策が重要であり、東京都の地下調節池などが事例として含まれる。本枠組みは自治体のインフラ計画や国土強靱化に示唆を与えるが、直接的なGX（脱炭素）や開示要件とは関連が薄い。
In the global GX context
Globally, this research contributes to climate adaptation and urban resilience discourse, complementing TCFD/ISSB climate risk assessments by providing a functional framework for infrastructure planning. It offers a scalable approach for cities facing flood risks, relevant to climate adaptation strategies and resilience building.

📄 Abstract（原文）
Contemporary approaches to urban water management increasingly rely on concepts such as Nature-Based Solutions (NBSs), Green Infrastructure, and Blue-Green Infrastructure. Although these frameworks have gained broad acceptance, their typological character provides limited guidance for project-oriented decision-making, as they primarily describe infrastructure types rather than their functions within integrated hydrological systems. To address this gap, this study proposes a complementary functional-operational framework for interpreting ecological infrastructures in urban flood mitigation. Employing a qualitative comparative case study methodology, we analysed four diverse international models—the Dutch Water Squares (Rotterdam), Tokyo’s underground flood control system, Copenhagen’s Cloudburst Management Plan, and Singapore’s ABC Waters Programme—to examine the systemic interaction between grey, green, and blue infrastructures at different watershed scales. The results indicate that flood mitigation effectiveness depends less on the predominance of a single infrastructure type and more on the functional coupling among them. Specifically, three primary functions were identified: rapid conveyance (grey infrastructure), infiltration and thermal regulation (green infrastructure), and dynamic storage and biodiversity support (blue infrastructure). Despite the contextual limitations and varying scales of the selected cases, blue infrastructure universally emerges as a systemic buffer that enhances urban resilience by regulating excess volumetric flows. Ultimately, the proposed framework introduces an actionable interpretative layer that complements existing typological classifications, providing planners and urban designers with a robust, scalable basis for implementing integrated ecological infrastructures.
