Cities Aren’t Prepared for a Crucial Part of Sea-Level Rise: They’re Also Sinking

As sea levels continue to rise due to climate change, cities around the world are facing the threat of increased flooding and storm surges. However, there is a lesser-known but equally important factor at play: land subsidence, or sinking of the ground.

Many cities, especially those built on coastal areas or river deltas, are experiencing land subsidence due to factors such as excessive groundwater extraction, natural compaction of sediments, and inadequate infrastructure maintenance. This, coupled with rising sea levels, poses a double threat to these vulnerable urban areas.

Without proper mitigation measures, cities could face catastrophic consequences, including more frequent and severe flooding, damage to infrastructure, and displacement of communities. It is crucial that city planners and policymakers take into account both sea-level rise and land subsidence in their adaptation strategies.

Investing in measures such as improved drainage systems, sustainable groundwater management, and coastal defenses can help mitigate the impacts of both sea-level rise and land subsidence. Additionally, raising awareness among the public about the dual threat of sinking cities is essential for building community resilience and preparedness.

In conclusion, addressing sea-level rise is only part of the solution. Cities must also take into account the sinking ground beneath their feet in order to effectively adapt to the changing climate and protect their populations from the growing risks of flooding and other hazards.
