Identifying the best strategies and actions for cities to build urban resilience: a review of the evidence

Cities play a key role in managing and preparing for local emergencies, such as flooding events. Better urban planning, design and management can help reduce environment and health impacts. Source: Unsplash, Juan Manuel Sanchez.

Cities need to be aware of their vulnerabilities to local emergencies. They also need to understand which urban planning, design and management strategies work best to build resilience. We reviewed the latest scientific evidence to identify the most effective preparedness strategies for different emergency scenarios, analysing co- and dis-benefits among them. Ideas and tools for local authorities and communities in general to build back better.

The problem

Cities can contribute a lot to health protection and wellbeing through urban resilience strategies and action. To do so, they need to know about what strategies are available and have proven to be effective in other cities, and understand the co- and dis-benefits among them. The academic literature about these links between health, urban planning and disaster management has not been consolidated; evidence from the local level is especially lacking.

What we did and why

In an aim to help local authorities and communities to build resilience, we carried out an evidence-based compilation of the best strategies and actions to build resilience at the local level. We identified a wide array of urban planning, design and management strategies, and analysed the co- and dis-benefits among them. We present them through eight cross-cutting issues (including urban form/models, green infrastructure, buildings, or transportation), making visible the environmental and health benefits associated with each strategy.

Our study’s contribution

This study brings together a wide array of strategies for local officers and planners to build resilience to emergencies; a compilation that (to the best of our knowledge) was not previously available, but rather dispersed in case studies and often focusing on single hazard types. The main contribution of this work is bringing together these concrete local actions through the lens of 8 cross-cutting issues related to urban planning and management, analysing how concrete actions might work together in an urban context.

Impacts for city policy and practice

The study can help local authorities and communities in general to:
• Understand/reflect on what type of vulnerabilities they might have to local emergencies and their associated environment and health impacts.
• Come up with ideas and tools to build resilience through concrete urban planning, design and management actions.
• Identify synergies, co-benefits and dis-benefits among strategies.
• Adopt an all-hazard, multi-risk approach to building urban resilience.
• Further integrate health protection considerations into mainstream urban planning and management.
