Adapting cities for climate resilience is crucial as climate change increases the frequency and severity of extreme weather events. This study outlines a comprehensive set of resilience strategies aimed at enhancing urban resilience across four key domains: water, food, shelter, and energy. These strategies, applicable to both new and existing neighborhoods, range from simple, short-term measures to complex, long-term initiatives. A three-pronged evaluation framework, consisting of three platforms, is introduced to assess these strategies where criteria are initially selected based on their impact on strategy adoption and implementation. This framework employs hypothetical scores and weights that can be adjusted for specific urban contexts through detailed studies. Key outcomes of the evaluation conducted in the first platform include a systematic method to rank strategies based on six criteria: cost, infrastructure impact, scalability, regulatory and zoning challenges, community acceptance, and maintenance needs. For example, community gardens and rainwater harvesting systems are highly scalable and accepted, whereas green roofs require more investment and maintenance. The second and third platform of the framework facilitate the identification of strategies that enhance resilience across each of the resilience domains, as well as across several domains. The results highlight the top-performing strategies under different weighted scenarios. Strategies like green roofs strategy scores high in domains like water management, due to its capacity to absorb and manage stormwater, and energy, by providing natural insulation that reduces heating and cooling demands. Additionally, green roofs contribute to food production when utilized for urban agriculture and enhance shelter by improving building durability and increasing biodiversity This data-driven framework supports the strategic prioritization of resilience strategies, enhancing urban planning and investment decisions globally. Its modularity ensures adaptability to diverse urban settings and climatic issues.

随着气候变化加剧极端天气事件的发生频率和严重程度,城市的气候适应能力至关重要。本研究概述了一套全面的抗灾战略,旨在提高城市在水、食物、住房和能源四个关键领域的抗灾能力。这些战略既适用于新建社区,也适用于现有社区,既有简单的短期措施,也有复杂的长期举措。为评估这些战略,引入了一个由三个平台组成的三管齐下的评估框架,其中的标准最初是根据其对战略采纳和实施的影响来选择的。该框架采用了假设分数和权重,可通过详细研究根据具体城市情况进行调整。第一个平台的主要评估成果包括根据成本、基础设施影响、可扩展性、监管和分区挑战、社区接受度和维护需求这六项标准对战略进行排序的系统方法。例如,社区花园和雨水收集系统具有很高的可扩展性和可接受性,而绿色屋顶则需要更多的投资和维护。该框架的第二和第三个平台有助于确定可增强每个复原力领域以及多个领域复原力的战略。结果突出显示了在不同加权情景下表现最佳的战略。绿色屋顶战略因其吸收和管理雨水的能力,在水资源管理等领域得分较高;绿色屋顶战略因其提供天然隔热性能,可降低供暖和制冷需求,在能源等领域得分较高。此外,屋顶绿化在用于城市农业时有助于粮食生产,并通过提高建筑耐久性和增加生物多样性来改善居住环境。其模块化设计可确保适应不同的城市环境和气候问题。
