Özet

Hızlı kentleşme ve iklim değişikliği ekseninde yerel yönetimler, kentsel iklim adaptasyonunda geleneksel gri altyapıyı, doğa temelli çözümleri (DTÇ) ve hibrit stratejileri nasıl konumlandıracakları sorunuyla karşı karşıyadır. Bu çerçevede çalışma, CDP-ICLEI Track 2025 dönemine veri sunan 833 kentte DTÇ'nin gri altyapıya kıyasla benimsenme örüntülerini betimsel-keşifsel bir yaklaşımla incelemeyi amaçlamaktadır. Araştırma, kamuya açık CDP-ICLEI Track veri seti üzerinden kentlerin adaptasyon eylemlerini, yönetişim göstergelerini, tehlike profillerini ve finansman kaynaklarını frekans analizi ve uyum analizi aracılığıyla incelemektedir. Analiz ve raporlamada Python programlama dili kullanılmıştır. Bulgular, kentlerin %59,4'ünün en az bir DTÇ eylemi raporladığını; ancak DTÇ'nin çoğu kentte gri altyapıyı ikame etmekten çok ona eşlik ettiğini göstermektedir. Adaptasyon stratejisi tehlike türüne göre sistematik biçimde farklılaşmakta; ekolojik tehlikelerde DTÇ, hidrolojik tehlikelerde gri altyapı öne çıkmaktadır. DTÇ uygulayan kentler incelenen tüm yönetişim göstergelerinde daha yüksek kurumsal kapasite sergilerken, her iki strateji de baskın biçimde yerel yönetim kaynaklarına dayanmaktadır. DTÇ projeleri çeşitlenmiş finansman kaynaklarına görece daha açık görünmektedir. Bulgular, DTÇ'nin evrensel bir alternatif değil, tehlike profiline göre konumlanan bütünleşik bir adaptasyon yaklaşımının parçası olarak değerlendirilmesi gerektiğine işaret etmektedir.

Abstract

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.
