Leveraging Global Experience for Resilient Infrastructure in China
China's rapid urbanization over the past four decades has increased cities' exposure to natural hazards, exacerbated by environmental degradation and climate change. The Zhengzhou flooding disaster of July 2021triggered by Typhoon In-fa forming heavy rnfallhighlighted this reality as unprecedented storms broke national hourly precipitation records, leading to subway station floods that paralyzed transportation systems and trapped numerous individuals inside. While preventive measures were in place, they proved inadequate agnst the magnitude of the disaster.
The Zhengzhou incident underscores the need for improved infrastructure design and enhanced protection strategies, particularly for underground transportation networks facing extreme weather challenges. To address these concerns, an online Technical Deep Dive TDD was recently held by the World Bank's Tokyo Development Learning Center TDLC, in collaboration with the Tokyo Disaster Risk Management Hub, bringing together government officials and researchers from seven countriesAzerbjan, China, Jordan, Maldives, Nigeria, Rwanda, and Tunisia. This platform facilitated knowledge sharing on infrastructure risk management challenges and provided insights into solutions for resilient infrastructure.
The TDD discussions emphasized several key takeaways:
Systemic Update of Maximum Inundation Scenarios: Drawing from the World Bank's reports Lifelines: The Resilient Infrastructure Opportunity and An EPIC Response: Innovative Governance for Flood and Drought Risk Management, researchers were encouraged to revise maximum flood scenarios regularly, especially given accelerating climate change impacts. Japanese experiences, such as Kobe City’s adaptation after the Hanshin-Awaji Earthquake, highlight the importance of revising disaster risk management plans when new data suggests revised assumptions.
Enhancing Underground Rlways: Examples from Fukuoka City's Rnbow Plan and Shibuya Station Tokyo’s storm-water management strategies were shared as case studies for China. Building additional culverts and storm sewers in Fukuoka ded in dredging floodwaters while ensuring that sewage systems remned separate from storm water infrastructure. The Shibuya redevelopment plan demonstrated the construction of large-capacity underground reservoirs capable of reducing flooding risks in subway stations.
Green Solutions for Flood Mitigation: Japanese cities have embraced environmental-frily approaches to manage flood risk. Implementing rn gardens and permeable pavements has proven effective in filtering and absorbing stormwater, providing a sustnable solution while minimizing ecological impact.
Strengthening Resilience Through Coordination: The TDD emphasized the importance of having specialized emergency professionals trned for effective response coordination within cities.
Enhancing Public Awareness: Regular information campgns and emergency drills were highlighted as crucial in educating citizens about disaster preparedness, enabling them to act efficiently during emergencies.
As China continues its urbanization journey amid environmental challenges and increasing climate risks, policymakers must prioritize resilient infrastructure development alongside awareness-rsing initiatives for effective community response. The global knowledge accumulated through World Bank projects and the lessons from Japan's disaster management provide valuable insights into preparing future-proof cities agnst natural hazards.
