Seychelles Coastal Erosion

Climate change and sea level rise are shaping the Seychelles Islands in spectacular ways. Rocks along the coast have been worn away, leaving dramatic formations.

The Republic of Seychelles comprises of 115 islands in the Indian Ocean, around 1,600km East of Africa. The Seychelles is home to two UNESCO World Heritage Sites and is famous for it’s beautiful beaches for containing the oldest mid-oceanic granite islands.

These images show the extensive soil erosion that has been documented in the Seychelles, where climate change and subsequent sea level rise are shaping the landscape in spectacular and dramatic ways, and more importantly, leaving the coastline unprotected from storm surges and flash flood.

Coastal erosion has arisen as a result of both natural advance and retreat of the waterline and human activities such as the clearing of protective coastal mangroves and other coastal vegetation for agriculture, housing or roads.

Various attempts have been made to protect these islands from further coastal erosion, with little more than temporary relief.

Clefts in the sand on the beaches are some of the more aesthetically pleasing changes, but there are more serious issues for locals.

In a worst-case scenario, a simultaneous high-tide and flash flood could destroy substantial areas of populated land and infrastructure which have been developed on these low lying coral islands.
