Disappearing Coasts: How Are Island Nations and Coastal Cities Fighting Rising Seas?
Seas are becoming deeper every year which leads to disappearing coasts, which is prompting island nations to react in many different ways.
How Are Island Nations Reacting?
The Maldives have elevated Hulhumalé to about 2 meters above sea level and in a 2026 paper, it claims that while other islands disappear, their own islands are expanding. Tuvalu reportedly reclaimed about 8 hectares in Funafuti. Since 2014, villages of Fiji have been relocating, as reported by our article on sinking islands.
What Are Cities Doing?
MOSE barriers of Venice have been closed for about 108 high tides between the years 2020 to 2025 and 30 times in early 2026 respectively, while its researchers conclude that no plan can safeguard the city as it is now. Even though Miami is elevating roads and utilizing pumps, seawater continues increasing in its porous limestone. In Jakarta, where land has gone down by around 2.5 meters over the last decade (disappearing coasts), is now constructing a wall against the sea and a new capital in the country.
Can Walls Save Lives?
Even though barriers give time, the experts are now starting to talk about managed transformation instead of preservation, like raising land or moving to location as well as reducing emissions. You may also refer to one of our articles regarding sinking cities.
