En Sibérie, il y a une cabane en bois discrète qui n'a l'air de rien au premier abord mais ce bâtiment anodin servira d'entrée à un coffre-fort qui pourrait un jour sauver la race humaine.
 
Une installation de stockage surnommée " l'Arche de Noé des semences" destinée à mettre à l'abri  les graines alimentaire et les plantes rares de la planète contre un cataclysme planétaire est sur le point d'être construite juste en dessous.
 
Cette installation utilisera le froid naturel du permafrost de Sibérie pour préserver des échantillons jusqu'à une période de 100 ans. Elle est en cours de construction pour un coût de 227 millions de roubles (3,2 millions £).
 
Au moins 1,5 million de graines de plantes, de légumes, de céréales et de diverses autres sources de nourriture, seront rangées dans l'unité spéciale de cryoconservation à Iakoutsk, la ville la plus froide de la planète.
 
D'après le "Sibérian Times", elle permettra aux scientifiques de protéger beaucoup d'aliments importants et la vie végétale en voie de disparition contre le changement climatique, les guerre et les cataclysmes.
 
En 2008, une installation similaire a été créée en Norvège, mais la nouvelle installation dans le nord de la Sibérie est la seule de son genre à utiliser uniquement le système de refroidissement du pergélisol naturel.
 
Il existe déjà une petite unité contenant 100 000 échantillons sur le site mais la construction d'une nouvelle extension va le transformer en  plus grand dépôt de la planète.
 
Georgy Kuzmin, chercheur principal à l'Institut du pergélisol, une partie de la Branche Sibérienne de l'Académie des sciences de Russie a déclaré : «Le projet n'utilise pas de machines, d'électricité ou de gaz, il n'utilise que le froid naturel et les coûts d'exploitation sont minimes.»
 
 
 
 
Le bâtiment unique n'utilise pas de ventilateurs ou de pompes pour maintenir constante la température sous la terre froide, il s'appuie simplement sur l'air froid naturel.
 
La nouvelle extension sera en mesure d'accueillir 1,5 million d'échantillons de semences en provenance de la Russie et du reste du monde.
 
 
 
 
 
Les scientifiques veulent préserver un grand nombre des espèces les plus menacées de plantes et veillent à garder un stock de semences communes qu'ils n'auront pas besoin de replanter, pour un maximum de 100 années.
 
Ces semences seront placées dans des récipients en verre scellés spéciaux,  les températures glaciales à l'extérieur les préservant dans un congélateur naturel géant.
 
 
 
 
 
 
L'installation similaire du Svalbard, en Norvège ne s'appuie que sur des systèmes de refroidissement artificiels avec un pergélisol à une température de -18 degrés Celsius.
 
Selon les scientifiques de Sibérie, elle est moins sûre en raison des dangers d'une panne de courant présentant un risque pour garder l'installation réfrigérée.
 
Le réchauffement climatique peut également augmenter les températures des champs de glace norvégiens et faire fondre le pergélisol, chose qui ne est pas possible dans la République de Sakha.
 
Nikolai Goncharov, de l'Institut de la cytologie et de génétique à Novossibirsk, a déclaré : «C'est un site éternel, respectueux de l'environnement et qui ne peut pas être affecté par des catastrophes.»

Underneath THIS tiny hut lies the 'Noah's Ark' for world's food supply: Vault deep beneath the coldest city on the planet to become home to massive stockpile of seeds and plants

  • Pioneering facility will use the natural cold of Siberia's thick permafrost to preserve samples for up to 100 years
  • At least 1.5million seeds - from plants and vegetables - will be housed in the cryostorage unit in Yakutsk
  • It will enable scientists to protect many of the world's important foods and endangered plant life against Doomsday

In Siberia, there is an inconspicuous wooden hut that doesn't warrant a second glance. But this unremarkable building will be the entrance to a vault that could one day save the human race.

A storage facility dubbed the 'Noah's Ark for seeds' that will safeguard the planet's food supply and rare plants against Doomsday is about to be constructed underneath it.

The pioneering facility will use the natural cold of Siberia's thick permafrost to preserve samples for up to 100 years.

Being built at a cost of 227 million roubles (£3.2million), at least 1.5million seeds - from plants, vegetables, cereals and other food sources - will be housed in the special cryostorage unit in Yakutsk, the coldest city on the planet.

It will enable scientists to protect many of the world's important foods and endangered plant life against climate change, war, and disaster, reported The Siberian Times.

In 2008 a similar vault was created in Norway, but the new facility in northern Siberia is the only one of its kind that solely uses the unique natural permafrost cooling system.

There is already a small unit containing 100,000 samples on the site, in the Sakha Republic, but a new purpose-built extension will turn it into the largest anywhere on the planet.

Georgy Kuzmin, lead researcher of the Permafrost Institute - part of the Siberian Branch of the Russian Academy of Sciences - said: 'The project does not use any machinery or electricity or gas.

'It only uses natural cold and, respectively, the operating costs are minimal.'

The first part of the cryostorage facility in Yakutsk was opened in December 2012, some 35 years after Soviet scientists began an experiment in a mine at the Permafrost Institute.

At a depth of 12 metres they began the long-term storage of seeds from legumes at a temperature of about -7C using just the natural cold from permafrost.

Scientists were able to prove that seeds can be stored at that temperature, rather than colder, without losing any of their germinating capacity.

Later, about 1,000 seeds from crops common in the Sakha Republic, also known as Yakutia, were added to the vault along with some endemic, rare and endangered plant species.

By the time the new facility opened in 2012, there were 11,000 samples and there is now currently space for about 100,000 seeds from around Russia.

The unique building does not use any fans or pumps to keep the temperature under the ground cool and instead simply relies on the natural cold air.

The new phase will be able to accommodate 1.5million seed samples, and will be filled with collections from Russia and the rest of the world.

Scientists aim to preserve many of the most endangered species of plants as well as keep a stockpile of common seeds for up to 100 years that they won't need to replant.

They will be placed inside special sealed glass containers, with the freezing temperatures outside preserving them in a giant natural refrigerator. 

There is a similar storage laboratory in Svalbard, in Norway, but it relies upon artificial cooling measures as well as permafrost to lower temperatures to -18 degrees Celsius.

This, according to scientists in Siberia, makes it less safe because of the dangers of a power outage posing a risk to the ability to keep the facility cool.

Global warming may also raise the temperatures of the Norwegian ice fields and melt the permafrost, something that is not possible in the Sakha Republic.

Nikolai Goncharov, from the Institute of Cytology and Genetics in Novosibirsk, said: 'When global temperatures get warmer by five degrees, the glaciers on Svalbard will melt.

'To melt the permafrost in Yakutia temperatures need to rise by about 20 degrees.

'So we have quite a unique situation in which the permafrost can create storage in natural conditions that will keep the desired temperature.

'It is an eternal, and environmentally-friendly, system that cannot be affected by any disasters.'
