HCMC is among the fastest sinking cities in the world, subsiding by 16.2 mm annually, with groundwater extraction and high-rise buildings to blame, a study has found.

 

The study, led by Singapore's Nanyang Technological University, noted that with sea levels rising as ice sheets melt, land subsidence would worsen this issue, Singaporean newspaper Straits Times reported.

 

Cheryl Tay, a PhD student at the university and the first author of the study, said as coastal cities in Asia focus on growth and urbanization, demand for groundwater extraction also increases, leading to rapidly sinking land.
