Engineering Strategies For Smart City Resilience

This is how China is designing flood-resistant cities. They are using modern technology that can be replicated in flood-affected areas around the globe. With a focus on innovative engineering and sustainable practices, Chinese urban planners are implementing advanced drainage systems, green spaces, and permeable surfaces to mitigate flooding risks. In cities like Zhengzhou, which experienced devastating floods in 2021, authorities are taking proactive measures by constructing elevated walkways, improving water retention areas, and incorporating natural features into urban landscapes. These strategies aim to absorb excess rainwater and reduce runoff, enhancing the resilience of urban infrastructure. Additionally, smart technologies such as real-time data monitoring and AI-driven predictive models are being integrated into city planning. These tools enable quick responses to weather changes, allowing for timely evacuations and better resource allocation during flooding events. China's approach not only addresses immediate flood risks but also promotes sustainable development by prioritizing environmental harmony. By sharing these technologies and strategies with other nations, China is leading the way in global efforts to combat climate change and protect vulnerable communities from the impacts of flooding. This comprehensive approach showcases the potential for innovation in urban planning, setting a precedent for flood resilience worldwide. ©: Business Insider

Extreme heat events pose significant risks to transportation infrastructure and services globally. Asphalt pavements, steel rails, aviation networks, public transit systems, and active transport modes face substantial pressures from heat exposure, with rippling impacts on operations, safety, user comfort, and asset maintenance costs. Elevated temperatures considerably accelerate road infrastructure deterioration, causing up to 75% reduction in pavement life by 2100. This necessitates various changes in standards (e.g. thickness increases and reconstruction expenses over $60,000 per km) to adapt pavements. Rutting emerges as the primary pavement failure mode, escalated by 0.036” to 0.134” over 100 years, with a strong correlation to temperature rise. Additionally, proactive climate adaptation strategies prove far less costly than reactive approaches for pavements. Some countries exhibit a 40x difference in costs between proactive and reactive strategies by 2100. In collaboration with Global Facility for Disaster Reduction and Recovery (GFDRR) and The World Bank we organized a set of expert working group meetings and developed an actionable, forward looking climate resilient agenda for preparing transportation systems for heatwaves. We have identified low regret strategies and adaptation pathways that cities can use to prepare transportation systems. Consideration of heat equity is an important part of this process. Our ideas are summarized today in the Nature Magazine paper (https://lnkd.in/gWDCMsKf) where we provide call for action to improve the resilience of global transport systems to future heatwaves. A full report that identifies the barriers, impacts, technologies and policy actions is in review and will be released in the future. If anyone is interested in discussing climate-resilient transportation systems and want to discuss these ideas, please feel free to get in touch with us.

Whiplash Weather: Building Resilience for Extreme Climate Events As our planet grapples with extreme weather events, the concept of ‘Whiplash Weather’ is becoming increasingly relevant. This phenomenon, characterized by rapid weather shifts from calm to extreme conditions, demands a proactive approach to ensure our communities are prepared and resilient. In a world of cities, underpinning urban planning with the Outdoor City framework is essential to help cities adpat to extreme weather, protect vulnerable neighborhoods and engage folks in a healthier outdoor centric lifestyle. Here’s a couple points from the Outdoor City strategy to fortify against these unpredictable climate patterns, including those noted in the #worldeconomicforum top global risks: 1. Enhance Natural Systems with Adaptive Strategies: By viewing natural systems through a lens of adaptability, we can strengthen their ability to cope with diverse weather conditions. This approach not only preserves the environment but also acts as a buffer against extreme weather. 2. Multifunctional Infrastructure for Whiplash Weather: As we develop infrastructure, it’s crucial to embrace a ‘Dig Once’ philosophy. This means designing spaces for multiple purposes, such as a playfield that doubles as a catchment area for groundwater runoff and storm surges. Efficient and versatile infrastructure is key. 3. Decentralizing Energy Resources for Resilience: Building a green, localized energy infrastructure is essential. This approach not only aids in creating a climate-resilient energy system for all weather conditions but also propels us towards a net-nature energy portfolio. 4. Cultivating a Dynamic Workforce at Innovation’s Forefront: There’s a growing need for first responders and disaster management experts. Embracing technology can enhance early warning systems, leading to better preparedness. We need a new generation equipped with tech skills at the intersection of innovation, readiness, and community involvement. 5. Community Empowerment for Enhanced Preparedness: Strong communities are the backbone of resilience. By building a volunteer corps and emphasizing better communication, including early warnings and local training, we can create a network of support. This approach ensures neighborhoods, cities, states, and nations are better prepared for the next extreme event. As we face the challenges of Whiplash Weather, these five strategies offer a roadmap for building resilience and ensuring a safer, more sustainable future for all. #extremeweather #adaptation #naturesolutions #urbanplanning #outdoorcity #davos
