Sinking islands, rising costs: The Maldives’ race against climate change

The Maldives are the lowest lying islands on Earth, and they’re sinking — by 2050, 80% of the island nation could become uninhabitable. The deterioration of coral reefs poses a threat to the country’s biodiversity, economy, and existence.

The capital city Malé has an elevation of only 2.3 meters above sea level at its highest point. More than 80% of the Maldives lie less than 1 meter above sea level. · Ishan Hassan, Ocean Image Bank
Since 1988, sea walls have been constructed to protect shorelines against erosion and sea level rise across the Maldives. The capital Malé is completely bordered by a sea wall.
Living coral is strong, unlike dead coral which are brittle and can easily break off during rough weather. When there is severe coral mortality, the subsequent reef degradation can lead to the height of the reef being reduced by as much as a meter, which is effectively the removal of a breakwater.

Coral bleaching is caused by rising sea temperatures and ocean acidification, threatening reef ecosystems, including those in the Maldives, which are the seventh largest in the word. · The Ocean Agency, Ocean Image Bank
The [fishing] industry is facing major declines in baitfish, which depend on coral reefs for habitat. Coral reefs are also nursery grounds for many pelagic and reef fish species that are commercially significant [...] A number of popular dive sites are now degraded, decreasing their economic and aesthetic value.

Fisheries account for 11% of total employment and 98% of exports in the Maldives.
The "City of Hope," Hulhumalé, is an artificial island built from seabed sand that serves as an extension of the capital, Malé, and is 3 feet higher than any natural island in the Maldives.
The majority of coral restoration projects in Maldives in the past three decades are centered around resort islands, which are largely disconnected from local communities. In the past few years, however, there have been increasing efforts from [...] island communities to restore their reefs. Adequate funding and technical support are barriers that are commonly faced to implement and scale up such projects.
