Scientists have made a groundbreaking discovery, identifying numerous cities around the world that are sinking at alarming rates. This finding has significant implications for coastal cities and their populations, with an estimated 200 million people potentially being forced to leave their homes in the future. The University of Rhode Island conducted a study analyzing 99 locations and found that many of these cities are sinking faster than sea levels are rising.
Among the most severely affected areas are Bangladesh, China, the Philippines, and Pakistan. These countries are experiencing sink rates of up to 5 cm per year. However, other regions are also at risk, including Tampa Bay, Auckland, Taipei, and Istanbul.
The study utilized satellite imagery spanning from 2015 to 2020 to reach these conclusions. Meng Wei, an oceanographer at the University of Rhode Island, highlighted the significance of these findings, stating that while many cities are preparing for rising sea levels, they are not adequately addressing the compounding effect of coastal subsidence.
Interestingly, the study also mentions Barcelona, although it is not sinking in general. The research identified specific areas, such as the airport, port, and a residential zone, that are sinking at a faster rate than the sea level is increasing.
The University of Rhode Island identified Chittagong in Bangladesh, Tianjin in China, Manila in the Philippines, and Karachi in Pakistan as the most severely sinking cities, with rates of up to 5 cm per year. One of the primary causes of these sinking coastal cities is excessive groundwater extraction. Additionally, increased human activity, such as mining and construction, is contributing to this issue.
Although the situation may seem dire, there is hope. If these affected communities make crucial decisions in the coming years, including changes in groundwater management, the sinking could potentially be alleviated.
It is essential for policymakers, city planners, and communities to be aware of this significant problem and take appropriate action to mitigate the sinking of these coastal cities. By addressing the root causes and implementing sustainable solutions, we can protect the livelihoods of millions of people around the world.
