Why are the coral reefs dying in the Maldives?
Why are the coral reefs dying in the Maldives?
The coral is not dead but is under stress, but is subject to increased chance of death. Temperature is not the only thing that can cause this; changes in light availability, nutrients or pH can also cause bleaching. In the Maldives, however, SST increase is the main driver.
What happened to the coral in the Maldives?
Maldivian coral reefs experienced two severe bleaching events in 1998 and in 2016. After the 1998 bleaching event, more than 90% of hard corals died (Bianchi et al., 2003, 2006), and it took 16 years for reefs to recover the pre-bleaching values of live hard coral cover (Morri et al., 2015).
What causes coral bleaching in the Maldives?
Two severe heat waves triggered coral bleaching and mass mortality in the Maldives in 1998 and 2016. The 2016 heat wave affected all reefs investigated, but reefs in atolls with higher human pressure showed greater coral mortality than reefs in atolls with lower human pressure.

Why is coral important to the Maldives?
Coral reefs in Maldives represent strategic natural offshore sea-defence. They are also important as habitat for baitfish and primary source of building material. Coral blocks have been historically mined and used for buildings and road construction.
Can coral recover from bleaching?
In some instances corals can recover from bleaching. If conditions return to normal, and stay that way corals can regain their algae, return to their bright colours and survive. It can take decades for coral reefs to fully recover from a bleaching event, so it is vital that these events do not occur frequently.
Where is the coral reefs of the Maldives?
