NbS - WATER MANAGEMENT

Title: Nature-based Solutions for Water Resilience in Thriving European Urban Areas

Abstract: Characterised by rising populations, consumption rates and persistent inequalities, cities are central to transformative economic and social development models. Traditional engineering approaches often fall short, revealing inefficiencies and vulnerabilities. The current trend emphasises urban adaptation and resilience through sustainable strategies that ensure a steady water supply while promoting ecological balance. This study identifies Nature-based Solutions (NbS) for water-sensitive European cities. Examining 77 projects in 46 cities, including interventions at three spatial scales, the paper highlights the importance of blue infrastructure and green space techniques. By improving flood protection, water quality and stormwater management, these strategies effectively mitigate the impacts of urban development, which is particularly relevant in Mediterranean countries facing water scarcity and more frequent extreme weather events. In summary, this study advocates a paradigm shift towards NbS to comprehensively address urban water challenges, promote sustainability and strengthen urban resilience in the face of escalating environmental pressures.

题目：基于自然的解决方案在欧洲繁荣城市地区的供水弹性

摘要：城市因其人口增长、消费率上升及持续的贫富不均而成为转型经济和社会发展模式的核心。传统的工程方法往往力不从心，暴露出其效率低下和脆弱性。当前的潮流强调通过可持续战略进行城市适应性和弹性建设，确保稳定的水源供应同时促进生态平衡。本研究旨在为对水敏感的欧洲城市识别基于自然的解决方案（NbS）。通过对46个城市的77个项目的考察，包括三个空间尺度的干预措施，论文突出了蓝色基础设施和绿色空间技术的关键作用。通过提升防洪能力、水质管理和暴雨径流管理，这些策略有效地缓解了城市发展的影响，这对于面临水资源短缺和极端天气事件发生频率增加的地中海国家尤为重要。总之，本研究倡导向NbS的范式转变，以全面解决城市水问题，促进可持续发展并增强城市面对日益加剧的环境压力的韧性。
