As flood risks increase, maintaining and upgrading these systems may become increasingly expensive.
Extreme weather events such as Hurricane Sandy demonstrated how vulnerable urban infrastructure can be when storm surges overwhelm protective barriers.
Scientists warn that future storms could have even greater impacts if subsidence and sea-level rise continue simultaneously.
A Global Urban Challenge
New York is not alone in facing this issue.
Many major cities around the world are experiencing significant land subsidence.
Among the most affected are:
Jakarta, Indonesia
Jakarta has become one of the fastest-sinking cities on Earth. Some districts have subsided by several meters over recent decades, prompting Indonesia to relocate parts of its national capital.
Mexico City, Mexico
Built on the former bed of Lake Texcoco, Mexico City continues sinking due to groundwater extraction and soft underlying sediments.
Shanghai, China
Rapid urban development and groundwater use have contributed to measurable land subsidence in parts of Shanghai.
Venice, Italy
Venice faces both subsidence and sea-level rise, creating ongoing challenges for preservation efforts.
These examples demonstrate that sinking cities are becoming a global concern as urban populations continue growing.
Can the Problem Be Stopped?
While it may not be possible to completely halt natural geological processes, cities can take steps to reduce their vulnerability.
