Your grandma is right. The bananas that you can buy today in your local supermarket are not as sweet as the ones that she ate in her childhood.

There are many types or “cultivars” of any given fruit—a cultivar is a cultivated plant that is chosen and given a special name because of its desired characteristics—and various types of cultivars (for example in apples, the Red Delicious in the 1870s) come in and out of favor over the years. In the middle of the 20th century, the dominant banana cultivar exported to North America and Europe was the Gros Michel. However, sometime around 1950, it became virtually extinct due to the rapid spread of the so-called “Panama Disease,” a fungal infection that attacks the roots of the banana plant. The Gros Michel was replaced with the more resilient but notably less tasty Cavendish cultivar.

Modern agriculture is generally focused on maximizing profit by extracting maximum possible crop yield. A small number of specially selected cultivars of any given crop are planted throughout the world, displacing in the process numerous other local varieties. This approach guarantees consistently high yields under normal conditions, but it also harbors a hidden danger.

Essentially, every single commercially grown plant is a clone of one of only a few specially selected strains of genetic material. Diversity of genetic material is thus reduced to a bare minimum, leaving crop species exposed to any disease that can exploit that single strain. With corn, wheat, and rice being grown worldwide in such a fashion, there is a concern that a newly mutated strain of fungus could wipe out an entire world crop in a matter of months, and cause massive food shortages.

To preserve the genetic diversity of major food crops, international institutions have established a series of green gene banks, which store samples of genetic material of various strains of each plant species.

The Svalbard Global Seed Vault is meant as a sort of safety net, a reserve of last resort and the vault functions like a genetic safety deposit box. It stores duplicate specimens from genebanks worldwide and each individual depositor owns the contents of their box. Access to individual specimens is regulated by their respective depositors.

The facility currently can conserve 4.5 million seed samples. With approximately 1.5 million distinct seed samples of crops thought to exist, the Svalbard Global Seed Vault can store roughly three of each sample. Under the current temperature conditions in the vault (temperatures similar to those in a kitchen freezer) the seed samples can remain viable to begin new crops for anywhere from 2000 to 20,000 years.

The seed bank is located in a purpose-built vault drilled into the side of a mountain on the northern island of Spitsbergen, Norway. The main storage is 120 meters inside a sandstone mountain, on a tectonically dead island. The vault employs robust security and preservation systems. Seeds are packaged in special four-ply packets and heat-sealed to exclude moisture. A local coal mine and power plant supply the electricity for refrigeration control. The northern location also serves as a natural fridge. In the case of complete power failure, at least several weeks will elapse before the temperature rises to the −3 degrees Celsius of the surrounding sandstone bedrock.

The Svalbard Global Seed Vault opened for deposits officially on February 26, 2008, with the construction of the vault financed entirely by the Norwegian Government. The operational cost is shared by Norway and the Global Crop Diversity Trust.
