ABSTRACT

City strategic plans and enabling policies provide a framework for and inform future development across multiple scales. An exemplar city strategic plan will be one based on evidence, enabled by complementary policy outcomes, and built on the knowledge of the existing landscape. This study evaluated the plan quality of eighteen metropolitan strategic plans for city members in the 100 Resilient Cities initiative. A protocol was developed containing thirty-two indicators to assess plans capacity to act as a strategic planning tool to develop, analyse and implement strategies for the Urban Heat Island (UHI) and climate change mitigation and adaptation. The evaluation indicated that strategies addressing the UHI are rarely included in metropolitan plans. Strategic plans showed a lack of evidence-base to inform the potential actions. Urban warming is often linked to extreme weather events anticipated under climate change, not the UHI as a systemic and increasing phenomenon. We recommend that the pathway to addressing UHI mitigation and adaptation may lie in its nexus to aspects of climate change that concurrently can serve to support liveable and resilient cities.

摘要

城市战略计划和扶持政策为跨多个规模的未来发展提供了框架并提供了信息。一个示例性的城市战略计划将基于证据，辅以互补的政策成果，并以对现有景观的了解为基础。这项研究评估了100个抗灾城市计划中针对城市成员的18个大都市战略计划的计划质量。制定了包含32个指标的协议，以评估计划的能力，以作为制定，分析和实施城市热岛（UHI）和缓解和适应气候变化战略的战略规划工具。评估表明，针对城市居民健康问题的战略很少纳入大都市计划中。战略计划显示缺乏足够的依据来告知可能采取的行动。城市变暖通常与气候变化下预期发生的极端天气事件有关，而不是UHI作为系统性和日益加剧的现象。我们建议解决UHI缓解和适应问题的途径可能在于其与气候变化方面的联系，这些方面可以同时支持可居住和有弹性的城市。
