都市の気候適応策として注目される自然を基盤とした解決策（NbS）について、リスクと実現可能性を統合した空間計画フレームワークを提案。バルセロナ、ボストン、ロッテルダムの3都市で、緑の屋根、透水性舗装、レインガーデン、都市公園の4タイプを対象に、洪水と熱ストレスに対する多災害リスクと実現可能性を空間分析。リスクと実現可能性の空間的クラスタリングを明らかにし、優先実施ゾーンと制約地域を特定。都市形態やガバナンスがNbS実装に与える影響を比較分析している。
English
This paper develops a transferable, SETS-based decision-support framework for spatially analyzing multi-hazard climate risk and feasibility of four nature-based solutions (green roofs, permeable pavements, rain gardens, urban parks) across Barcelona, Boston, and Rotterdam. Results reveal strong spatial clustering of risks and feasibility, with green roofs and permeable pavements highly feasible in dense, heat-prone areas, while rain gardens and parks are constrained by land and infrastructure. Overlaying risk and feasibility identifies priority zones for rapid implementation and flags high-risk/low-feasibility neighborhoods, supporting justice-oriented NbS planning.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では気候変動適応策としてNbSの導入が進むが、自治体ごとの計画策定に資する空間分析手法は限られる。本論文のフレームワークは、日本の都市部での洪水・熱ストレス対策の優先順位付けに応用可能であり、国土交通省や自治体の適応計画に示唆を与える。
In the global GX context
Globally, this paper contributes to the growing literature on climate adaptation and nature-based solutions by providing a transferable spatial planning framework that integrates risk and feasibility. It offers a comparative, cross-city perspective that can inform urban climate adaptation planning under frameworks like the EU's adaptation strategy and global resilience initiatives.

📄 Abstract（原文）
Abstract Urban areas increasingly turn to nature-based solutions (NbS) to adapt to climate-related risks, which require integrated and systemic planning evaluating risks and feasibility of implementation. Here we develop a transferable, SETS-based decision-support framework that spatially analyzes multi-hazard climate risk and feasibility for four NbS types: green roofs, permeable pavements, rain gardens, and urban parks, across Barcelona, Boston, and Rotterdam. Integrating spatial and statistical analyses, we identify where different kinds of NbS are both most needed and most feasible for mitigating urban flooding and heat stress. Results reveal strong spatial clustering of risks and feasibility across all cities, with heat risk showing the highest spatial autocorrelation. Across cases, green roofs and permeable pavements consistently exhibit high feasibility in dense, heat-prone urban areas, whereas rain gardens and urban parks are constrained by land availability and underground infrastructure. The comparative analysis highlights how urban morphology, governance structures, and socio-economic factors shape feasibility for NbS implementation. Overlaying risk and feasibility identifies priority high risk –high feasibility zones for rapid implementation and flags high-risk/low-feasibility neighborhoods where infrastructure deficits and vulnerability may constrain adaptation, supporting more justice-oriented, context-sensitive NbS planning.
