The citizens of Tristan da Cunha – the most remote inhabited islands on Earth – have banned fishing and mining in their waters, creating the largest no- take zone in the Atlantic and the fourth largest worldwide.

The volcanic archipelago, a UK dependent territory 2,400km west of Cape Town, with a population of fewer than 300, has designated nearly 700,000km² of sovereign waters (about three times the land area of the UK) a Marine Protected Area.

“Our life on Tristan da Cunha has always been based around our relationship with the sea,” said James Glass, who has served as Tristan da Cunha chief islander, in a statement. “The Tristan community is deeply committed to conservation: on land, we’ve already declared protected status for more than half our territory. But the sea is our vital resource, for our economy and ultimately for our long-term survival.”

The islands and their waters are, says Jonathan Hall, RSPB’s former head of UK overseas territories, “one of the most pristine temperate ecosystems on the planet.”

Albatrosses that feed along the South American and African coasts and shearwaters that feed off Ireland all come here to breed. Blue sharks – the most heavily fished of all sharks – come here to pup from all around the South Atlantic,” adds Hall.
