This report serves as a call to action to strengthen urban resilience in response to the growing challenges of land subsidence and climate-related risks. It aims to raise awareness of land subsidence and its compounding effects when combined with sea-level rise and extreme weather events. Rather than offering technical solutions, the report provides high-level, foundational insights into the issue of sinking cities, presents four illustrative use cases and offers actionable recommendations for public and private sector stakeholders. By framing land subsidence as a critical factor accelerating the impacts of climate change in urban environments, the report underscores the need for cohesive, coordinated, cross-sector dialogue and long-term resilience planning. Without consensus-driven, decisive and collective action, many of the world’s most dynamic coastal and inland cities will face increasing threats to their prosperity and liveability. –National and local governments: Policy- makers can use this report to deepen their understanding of the drivers and impacts of subsidence, draw lessons from the strategies adopted by peer cities and identify opportunities for collaboration with other sectors. –Private sector: Businesses with operations or supply chains in affected areas can use the report to investigate their exposure to subsidence-related risks. They can explore opportunities to address the root causes and develop adaptive solutions across markets in collaboration with relevant stakeholders. For the purposes of this report, “sinking” refers specifically to land subsidence, the downward movement of the Earth’s surface. While many locations may experience sinking due to sea-level rise or other factors, this report relates sinking to subsidence as a standalone phenomenon and its interaction with climate risks such as sea-level rise and extreme weather. Additionally, data is taken from different sources and publications, highlighting the challenge of fragmented information; yet, the findings point to similar outcomes.How to use this report Resilient Economies: Strategies for Sinking Cities and Flood Risks 10
