How agricultural scientist Nicolai Vavilov shaped global crop preservation

Agricultural scientist Nicolai Ivanovich Vavilov, who lived from 1887 to 1943, established the world's first global seed bank in 1921 in Leningrad, now known as St. Petersburg. Vavilov traveled the world to collect seeds and crop varieties, gathering around 2.5 lakh varieties and species. He built this facility while working in the former USSR, and later inspired scientists to protect the seed bank during the Second World War despite dying in prison himself. One of his biggest contributions was a 1926 paper titled 'Studies on the origin of cultivated plants'. This work remains a key foundation today for studying and using crops and livestock, helping to protect plant genetic resources and farmer rights while also supporting the United Nations Convention on Biological Diversity. By combining genetics, evolutionary biology, and field studies across the former Soviet Union, Vavilov discovered that most of our crops came from just eight distinct regions of the world. He was the first person to map out these areas, which he called the centres of origin. His research showed that crop varieties and wild relatives are usually tied to specific geographic regions shaped by evolution and prehistoric human culture. While modern molecular biology notes that the centre of diversity may not always match the exact origin point of a crop, Vavilov's core concepts and collections continue to guide modern plant science and biodiversity discussions.
