In hopes of bolstering our defenses in the event of a major food crisis, researchers sent tens of thousands of seeds from different types of rice last week to a "doomsday vault" in the archipelago Svalbard.
為圖壯大我們的防禦在一主要的糧食危機事件,研究人員上週送出數以萬種不同類型的水稻種子,往一在斯瓦爾巴群島的“末日庫”。
Contained in black boxes, the 42,627 samples of rice seeds traveled to the mountains of the Norwegian archipelago, about 746 miles (1,200 kilometers) from the North Pole. The Svalbard Global Seed Vault is buried deep inside the icy mountains, where it protects all of the world's important crop seeds in case of a man-made or natural disaster.
以黑盒裝載,42,627種的水稻種子樣版被送往挪威群島的山區,從北極大約七四六英里(1200公里)。斯瓦爾巴德全球種子庫是深埋在冰冷的山上,在那裡它保護世界上的所有重要農作物種子,假若有一人為或自然的災害。
The rice collection was sent from the International Rice Research Institute (IRRI), whose first deposit to the doomsday vault included 70,180 rice-seed samples sent in 2008. If ideal temperature and storage conditions remain inside the vault, seeds can be stored for hundreds of years, scientists say.
水稻的種類是由國際水稻研究所(IRRI)送出,它的第一筆末日庫存儲在2008年發出,包括70,180種水稻種子樣品。如果末日庫內的理想溫度和貯存條件依然,種子可以保存數百年,科學家們說。

北極熊的保護
Polar bear protection

The giant icebox of sorts, which was officially opened on Feb. 26, 2008, is designed to protect the world's crop diversity from natural or man-made disasters.

The vault, which officially opened on Feb. 26, 2008, is dug into the Platåberget mountain ("plateau mountain") located near the village of Longyearbyen, Svalbard – a group of islands north of mainland Norway. The arctic permafrost offers natural freezing for the seeds, while additional cooling brings the temperatures down to minus 0.4 degrees Fahrenheit (minus 18 degrees Celsius).

And if the mountain of snow enshrouding the storage rooms wasn't enough protection, what better bodyguard than one of nature's biggest beasts.

"The region on Svalbard surrounding the seed vault is remote, severe, and inhabited by polar bears," according to the Global Crop Diversity Trust, which helps to support the vault's operations.

The preciousness of such seeds is reflected in the inaccessible nature of the vault. "Anyone seeking access to the seeds themselves will have to pass through four locked doors: the heavy steel entrance doors, a second door approximately 115 meters down the tunnel and finally the two keyed air-locked doors," the Trust writes. "Keys are coded to allow access to different levels of the facility. Not all keys unlock all doors."

故障安全備份
Fail-safe backup
Like all seeds coming to the vault, the new ones are duplicates of those from other collections – in this case, duplicates are from those kept by IRRI's International Rice Genebank in Los Baños, in the Philippines.

So if seeds are lost due to natural disasters, war, or lack of resources, the seed collections can be reestablished from Svalbard.

The vault can hold 4.5 million seed samples — and since each sample contains about 500 seeds, a maximum of 2.25 billion seeds will fit into the vault. That means all the unique seed samples conserved today by the 1,400 or so genebanks located across the globe could have duplicates in the seed vault.
