"Svalbard Global Seed Vault: 16,676 Seed Samples Banked in October as Ukraine Deposits Crops Under Fire"

On 13 October 2026, twenty-one genebanks from around the world added 16,676 seed samples to the Svalbard Global Seed Vault, the backup drive for the world's crops, buried in a mountain outside Longyearbyen, Norway. The shipment filled 47 boxes and took the vault's holdings past 1.4 million samples. Each sample is a duplicate of a collection held somewhere else on Earth, stored so that if the original is lost, the crop is not.

The vault, opened in 2008 and owned by Norway, is managed in partnership by the Norwegian Ministry of Agriculture and Food, NordGen and the Crop Trust. It has room for 4.5 million samples and is opened roughly three times a year. The October deposit was the year's second, following a February deposit that brought the first seeds from Guatemala and Niger and the vault's first-ever olive seeds. Days later, the vault's role earned it the 2026 Princess of Asturias Award for International Cooperation.

The largest contributors this time were the international research centres whose collections underpin breeding worldwide. The Mexico-based International Maize and Wheat Improvement Center (CIMMYT) sent 3,370 samples of wheat, triticale and maize; the International Center for Agricultural Research in the Dry Areas (ICARDA) in Lebanon sent 2,039; and the International Rice Research Institute (IRRI) sent 1,890 rice samples, including 410 first-time deposits, taking its backup coverage to 99.59% of its fully curated collection. The International Potato Center, which deposited wild potato and sweetpotato relatives, has now backed up 91% of its collection at Svalbard.

The deposit that says the most about why the vault exists came from Ukraine. Its National Center for Plant Genetic Resources sent 773 samples, including buckwheat, barley, millet and triticale, prepared and shipped while war puts its own genebank infrastructure at risk. Its head, Viktor K. Riabchoun, put the logic plainly: safety duplication means valuable genetic resources can be recovered if the original collection is damaged or lost. Italy's Council for Agricultural Research and Economics (CREA) joined as a first-time depositor with 271 samples of historic wheat and rice varieties, including Mentana, a wheat bred in the early twentieth century whose genes went on to feed wheat varieties around the world.

This is not the first time the backup has been called on. In 2015, ICARDA was forced to evacuate its headquarters in Aleppo, Syria, as war escalated, and withdrew seeds from Svalbard to replant its collection in Lebanon and Morocco, later returning a copy to the vault. That remains the vault's proof of concept: a duplicate is only worth something on the day the original fails, and on that day it is worth everything.

The numbers also show how the work is accelerating. In 2024, a record 61 genebanks deposited more than 64,000 samples, including 21 institutions depositing for the first time. The vault's collection stood at 1,378,238 samples at the end of 2025, and the October 2026 deposit alone added nearly 17,000 more. The question now is not whether the vault works. It is whether deposits keep pace with the diversity being lost in farmers' fields, where a variety that stops being grown stops existing except in a genebank. Svalbard cannot preserve what nobody bothers to send, and every deposit is a decision, made by people like the Ukrainian team working near hostilities, that some particular seed is worth carrying into the future.
