But the researchers at Icarda had a backup copy. Beginning in 2008, long before the war, Icarda had begun to send seed samples â âaccessionsâ as they are called â to the Svalbard Global Seed Vault, the so-called doomsday vault, burrowed into the side of a mountain on a Norwegian island above the Arctic Circle. It was standard procedure, in case anything happened.
War happened. In 2015, as Aleppo disintegrated, Icardaâs scientists borrowed some of the seeds they had stored in Svalbard and began building anew. This time, they spread out, setting up one seed bank in Morocco and another just across Syriaâs border with Lebanon in this vast valley of cypress and grapes known as the Bekaa.
âWe are doing our best to recreate everything we had in Aleppo,â Mr. Shehadeh said.
The Aleppo headquarters still contains the largest collection of seeds from across the region â 141,000 varieties of wheat, barley, lentils, fava and the like â though neither Mr. Shehadeh nor his colleagues know what shape itâs in. They havenât been able to return.
Seed banks have always served as important repositories of biodiversity. But theyâre even more crucial, said Tim Benton, a food security expert at the University of Leeds, at a time when the world needs crops that can adapt to the rapid onset of climate change.
âWe have to grow considerably different things in considerably different ways,â Mr. Benton said. âCertainly for our prime crops, like wheat, the wild relatives are thought to be really important because of the genes that can be crossed back into the wheat lines we have in order to build resilience and adaptation to climate change.â
Especially important, Mr. Benton said, because they could easily vanish without protection.
