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, many coastal cities around the world are facing the threat of flooding and inundation. However, a crucial part of this issue that often goes overlooked is the fact that many of these cities are also sinking.

Subsidence, or the gradual sinking of the land, is a serious issue in many coastal areas. This subsidence can be caused by a variety of factors, including the extraction of groundwater, the construction of buildings and infrastructure, and natural geological processes. In some cities, the rate of subsidence is even faster than the rate of sea-level rise, exacerbating the risk of flooding and increasing the vulnerability of these areas to the impacts of climate change.

Despite the growing recognition of the threats posed by sea-level rise, many cities are not adequately addressing the issue of subsidence. In order to effectively adapt to and mitigate the impacts of climate change, it is crucial that cities take into account both sea-level rise and subsidence in their planning and development efforts.

By implementing measures to address subsidence, such as restricting groundwater extraction, improving building codes, and investing in sustainable infrastructure, cities can help to build resilience against the dual threats of sea-level rise and sinking land. Failure to address subsidence could have disastrous consequences for coastal communities, leading to increased flooding, property damage, and displacement of residents.

It is clear that cities need to act urgently to address the complex and interconnected challenges of sea-level rise and subsidence. By taking proactive steps to mitigate these issues, cities can better prepare themselves for the impacts of climate change and ensure the long-term sustainability and resilience of their communities.
