本研究は、CDP-ICLEI Track 2025に報告した833都市を対象に、気候適応における自然基盤ソリューション（NbS）とグレーインフラの採用パターンを分析した。頻度分析とコレスポンデンス分析の結果、NbSはグレーインフラを補完する形で採用され、生態系ハザードではNbS、水象ハザードではグレーインフラが優先されることが示された。NbS採用都市はガバナンス指標が高く、資金源も多様である。
English
This study analyzes adoption patterns of nature-based solutions (NbS) and grey infrastructure in climate adaptation across 833 cities reporting to the CDP-ICLEI Track 2025. Using frequency and correspondence analysis, it finds NbS complements rather than substitutes grey infrastructure, with NbS prominent for ecological hazards and grey infrastructure for hydrological ones. Cities adopting NbS show higher governance capacity and more diversified funding sources.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本の自治体は気候変動適応計画を策定しており、NbSの位置づけは重要。本研究成果は、ハザード特性に応じた適応策の選択や、自治体のガバナンス能力向上の根拠として活用できる。また、CDP-ICLEIへの報告が国際的なベンチマークとなる中、日本の都市の適応戦略を国際比較する際の参考になる。
In the global GX context
This study contributes to global climate adaptation scholarship by providing empirical evidence on NbS adoption patterns across 833 cities. It aligns with international frameworks like the CDP-ICLEI Track and informs policy on integrating NbS into urban adaptation planning. The findings support the global push for nature-based solutions as part of climate-resilient development.

📄 Abstract（原文）
Amid rapid urbanization and climate change, local governments face the challenge of how to position conventional grey infrastructure, nature-based solutions (NbS), and hybrid strategies within urban climate adaptation. In this context, this study aims to examine, through a descriptive-exploratory approach, the patterns of NbS adoption relative to grey infrastructure across 833 cities reporting to the CDP-ICLEI Track 2025 cycle. The research examines cities' adaptation actions, governance indicators, hazard profiles, and funding sources drawn from the publicly available CDP-ICLEI Track dataset, using frequency analysis and correspondence analysis. The Python programming language was used for analysis and reporting. The findings show that 59.4% of cities reported at least one NbS action; however, in most cities NbS complements grey infrastructure rather than substituting it. Adaptation strategy differs systematically by hazard type, with NbS prominent for ecological hazards and grey infrastructure dominant for hydrological ones. While cities adopting NbS display higher institutional capacity across all governance indicators examined, both strategies depend predominantly on local government resources. NbS projects appear comparatively more open to diversified funding sources. The findings indicate that NbS should be regarded not as a universal alternative but as part of an integrated adaptation approach positioned according to hazard profile.
