Coastal cities around the world face the pressing threat of sinking due to various factors, including land subsidence and rising sea levels. Among the fastest sinking coastal cities are Jakarta, Indonesia, experiencing rapid subsidence exacerbated by excessive groundwater extraction. Venice, Italy, famed for its canals, sinks at an alarming rate due to natural compaction of its underlying sediments and groundwater extraction. New Orleans, USA, contends with both subsidence and the weight of urban infrastructure, exacerbated by the loss of natural protective wetlands. These cities grapple with urgent challenges, highlighting the imperative for sustainable urban planning and climate adaptation measures.
