Two-thirds of the world’s food comes today from just nine plants: sugar cane, maize (corn), rice, wheat, potatoes, soybeans, oil-palm fruit, sugar beet and cassava. In the past, farmers grew tens of thousands of crop varieties around the world. This biodiversity protected agriculture from crop losses caused by plant diseases and climate change.Today, seed banks around the world are doing much of the work of saving crop varieties that could be essential resources under future growing conditions. The Svalbard Global Seed Vault in Norway supports them all. It is the world’s most famous backup site for seeds that are more precious than data.Tens of thousands of new seeds from around the world arrived at the seed vault on Svalbard, a Norwegian archipelago in the Arctic Ocean, in mid-October 2024. This was one of the largest deposits in the vault’s 16-year history.And on Oct. 31, crop scientists Cary Fowler and Geoffrey Hawtin, who played key roles in creating the Global Seed Vault, received the US$500,000 World Food Prize, which recognizes work that has helped increase the supply, quality or accessibility of food worldwide.The Global Seed Vault has been politically controversial since it opened in 2008. It is the most visible site in a global agricultural research network associated with the United Nations and funders such as the World Bank.These organizations supported the Green Revolution – a concerted effort to introduce high-yielding seeds to developing nations in the mid-20th century. This effort saved millions of people from starvation, but it shifted agriculture in a technology-intensive direction. The Global Seed Vault has become a lightning rod for critiques of that effort and its long-term impacts.I have visited the vault and am completing a book about connections between scientific research on seeds and ideas about immortality over centuries. My research shows that the Global Seed Vault’s controversies are in part inspired by religious associations that predate it. But these cultural beliefs also remain essential for the vault’s support and influence and thus for its goal of protecting biodiversity.[embedded content]Backup for a global networkSeveral hundred million seeds from thousands of species of agricultural plants live inside the Global Seed Vault. They come from 80 nations and are tucked away in special metallic pouches that keep them dry.The vault is designed …
