In Norway's Svalbard archipelago, inside a mountain and near the Arctic town of Longyearbyen, lies the Svalbard Global Seed Vault — a monumental project aimed at safeguarding global biodiversity in crops. Celebrated for its robust structure, the vault is cut deep into the permafrost, making it an ideal repository for the world’s agricultural seeds. Its primary role is to serve as the ultimate safeguard against accidental losses in genebanks around the world due to natural disasters, equipment failures, wars, and other calamities.
The vault, which was opened in 2008, has received many contributions over the years, one of the more recent being a shipment of tomato seeds from Algarrobo, a municipality on Spain’s Costa del Sol. This deposit is a collaborative effort with a Spanish research center aimed at preserving genetic diversity in the humble tomato — a staple in global diets.
The reason for selecting this location in the Arctic Circle for the vault is primarily due to its geological stability and cold climate. These conditions are optimal for seed preservation. The permafrost offers a natural freezing barrier, maintaining the seeds in frozen stasis at -18 degrees Celsius (-0.4 degrees Fahrenheit), even in the event of power loss which could compromise artificial cooling systems. Positioned around 130 meters (426 feet) above sea level ensures the vault is safe from potential sea-level rises.
Capable of storing up to 4.5 million seed samples, the Svalbard Global Seed Vault acts as a backup for the world's 1,700 genebanks and any community gardens or local seed-saving projects that request to use the facility. Each seed sample submitted to the Seed Vault remains the property of its depositor, who has the sole right to access and use the seeds.
Importantly, the Seed Vault is not without its concerns and challenges. For example, in 2017, the entrance tunnel was flooded due to melting permafrost, though no seeds were harmed. This incident led to the upgrading of the vault, highlighting the challenges of maintaining a facility meant to potentially last centuries.
By sending seeds from regions like the sunny Costa del Sol to the cold confines of the Svalbard archipelago, researchers underscore a commitment to global agricultural resilience. As climate change poses increasing risks to biodiversity, such seed banks will play a crucial role in ensuring that the genetic diversity of the world’s food crops is not only maintained but protected for future generations. The Svalbard Global Seed Vault stands as a significant global initiative in this urgent and ongoing endeavor.
