日本語
イタリア・カターニアのトンド・ジョエニ流域を対象に、水文・水理モデル（HEC-RAS）と空間分析、都市計画基準を統合し、高密度市街地で自然基盤ソリューション（NBS）を導入すべき優先地区を特定する手法を提示した。洪水ハザード・リスクマップと土地利用・脆弱性・所有権等を重ね合わせた多基準評価により、ピーク流量抑制と浸透促進に有効な未建設地を抽出。NBS導入の大きな機会と、高密度市街地ゆえの制約の両方を示し、地中海都市の気候 resilient な雨水管理の意思決定を支援する。
English
This study develops an integrated methodology combining HEC-RAS hydrological-hydraulic modelling, spatial analysis, and planning criteria to identify and prioritize Nature-Based Solution (NBS) sites in the densely built Tondo Gioeni catchment in Catania, Italy. Flood hazard and risk maps for multiple return periods were overlaid with land-use, morphological, vulnerability, and land-ownership data in a multi-criteria evaluation. Results reveal significant opportunities for targeted NBS to mitigate peak flows and enhance infiltration, while highlighting constraints in compact urban settings, supporting climate-resilient stormwater management decisions in Mediterranean cities.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本でも都市型洪水・内水氾濫対策は喫緊の課題であり、グリーンインフラや流域治水の推進と親和的。ただし本論文は適応策・都市計画の枠組みが中心で、SSBJ・有報・TCFD等の開示制度との直接的な接続は薄い。日本の自治体・建設コンサルがNBS立地評価の手法論として参照する価値はある。
In the global GX context
Globally, this contributes to the growing literature on urban climate adaptation and green infrastructure, relevant to CSRD/TCFD physical-risk disclosure and municipal resilience planning. It offers a replicable multi-criteria framework for prioritizing NBS in dense Mediterranean cities, though it does not engage with corporate disclosure standards or transition finance directly.
👥 読者別の含意
🔬研究者:都市水文学・空間計画・多基準評価を統合したNBS立地選定手法の実証例として参考になる。
🏢実務担当者:建設・不動産・自治体の担当者が、内水氾濫リスクの高い市街地でグリーンインフラ候補地を評価する際の手順として活用可能。
🏛政策担当者:都市計画・治水政策において、NBSを優先的に配置するための評価基準設計の参考になる。
📄 Abstract（原文）
This study presents an integrated methodology for identifying and prioritizing suitable areas for Nature-Based Solutions (NBS) in highly urbanized Mediterranean contexts, focusing on the Tondo Gioeni catchment in Catania (Italy). The approach combines hydrological–hydraulic modelling, spatial analysis, and planning-based criteria to address increasing flood risks driven by extreme rainfall events and compact urban development patterns. Flood hazard and risk maps were produced using HEC-RAS simulations for different return periods, highlighting critical zones requiring intervention. These results were overlaid with land-use, morphological, and environmental datasets to identify unbuilt areas where NBS could effectively mitigate peak flows and enhance infiltration. Additional urban determinants, including zoning regulations, planning frameworks, population vulnerability, and land ownership, were incorporated into a multi-criteria evaluation to assess the feasibility and transformability of each site. Preliminary findings reveal significant opportunities for targeted NBS implementation but also emphasize the constraints associated with highly built-up urban settings. The proposed framework supports decision-making processes that integrate engineering, ecological, and planning perspectives for climate-resilient stormwater management in Mediterranean urban environments
