The vault is on the Norwegian island of Spitsbergen and contains almost a million packets of seeds, each a variety of an important food crop. When it was opened in 2008, the deep permafrost through which the vault was sunk was expected to provide “failsafe” protection against “the challenge of natural or man-made disasters”.
In an international ceremony in 2015, representatives of the Andean indigenous communities who helped establish the Potato Park in Cusco, Peru, deposited 750 (types of?) potato seeds in the Svalbard seed vault.

According to the Svalbard vault database 712603 potato seeds from 4280 accessions from 6 genebanks are currently stored.
Hege Njaa Aschim, from the Norwegian government, which owns the vault:
“It was not in our plans to think that the permafrost would not be there and that it would experience extreme weather like that.”Fortunately, the meltwater did not reach the vault itself, the ice has been hacked out, and the precious seeds remain safe for now at the required storage temperature of -18C.
“A lot of water went into the start of the tunnel and then it froze to ice, so it was like a glacier when you went in,”

Hege Njaa Aschim:
“It was supposed to [operate] without the help of humans, but now we are watching the seed vault 24 hours a day.”The vault’s managers are now waiting to see if the extreme heat of this winter was a one-off or will be repeated or even exceeded as climate change heats the planet. The end of 2016 saw average temperatures over 7C above normal on Spitsbergen, pushing the permafrost above melting point.
“We must see what we can do to minimise all the risks and make sure the seed bank can take care of itself.”
Hege Njaa Aschim:
“The question is whether this is just happening now, or will it escalate?”The Svalbard archipelago, of which Spitsbergen is part, has warmed rapidly in recent decades, according to Ketil Isaksen, from Norway’s Meteorological Institute.
The vault managers are now taking precautions, including major work to waterproof the 100m-long tunnel into the mountain and digging trenches into the mountainside to channel meltwater and rain away.
They have also removed electrical equipment from the tunnel that produced some heat and installed pumps in the vault itself in case of a future flood.
Aschim said there was no option but to find solutions to ensure the enduring safety of the vault:
“We have to find solutions. It is a big responsibility and we take it very seriously.”
“We are doing this for the world.”
