Buried deep inside the Arctic Circle, the Global Seed Vault is a giant project that protects the world’s most valuable seeds from global disasters and ensures the world’s food supply. Opened in 2008, it has been described as ‘the ultimate back up plan’. Permafrost and thick rock ensure that the seeds remain frozen in the vault even without power. However, in May 2017 meltwater gushed into the entrance of the vault, it was produced as a result of rising temperatures in the Arctic caused by climate change. Though the meltwater did not reach the seeds, there is now growing concern that the Global Seed Vault is no longer an impenetrable policy for the humanity’s food supply. This resource takes a look at what happens at the vault, the geopolitics of seed saving, and how climate change may be changing the landscape of Svalbard.

Where is the Global Seed vault?

The Global Seed Bank is based on the Norwegian Island of Spitsbergen, part of the Svalbard archipelago which is located in the Arctic Ocean, halfway between Norway and the North Pole. Buried over 100 meters deep into a mountain, it is one of the world’s largest untouched areas and it is the farthest north that a person can reach on a scheduled flight. This makes it an ideal location for the vault because it is both remote yet accessible. The area itself is geologically stable and humidity levels are low. It is also well above sea-level therefore protected from ocean flooding according to worst case scenario sea level rises.

Why was the Global Seed Vault established?

There are many national, regional and international seed collections and gene banks around the world at various institutions and universities. For example, the Millennium seed bank which is based in Royal Botanic Gardens at Kew in London and aims to preserve the botanical heritage of the UK. But these seedbanks are vulnerable to potential damage from external forces such as extreme weather, or conflict, but also from everyday accidents such as fires.

The Global Seed Vault was opened by the Norwegian Government in February 2008 and is managed in partnership with the Crop Trust. As the environmental, social and political landscape of the world changes it is important to keep as many different crop varieties as possible for future scenarios where food supply may be in jeopardy. Alongside the national seedbanks that exist, scientists and researchers working at these gene banks will also send copies to Svalbard to ensure there is a back-up.

What happens there?

Currently, there are around 930,000 samples of seeds held in the vault. It has the capacity to store 4.5 million varieties - with each sample of that variety containing around 500 seeds - meaning that in total 2.5 billion seeds can be housed in the Global Seed Bank.

A temperature of -18ºC is required for optimal storage of the seeds and they are stored in special foil packages which are sealed in boxes and stored on shelves. The vault has low metabolic activity as a result of low temperature and moisture levels and this ensures the seeds are safe for a long period of time.

Why is international co-operation important to the success of the seedbank?

Any organisation or country can send seeds to the vault; there or no restrictions. This means that the vault is an example of international co-operation towards global issues. Without the unique environment of the Global Seed Vault national seedbanks are potentially more precarious. They can be compromised by natural disasters and geopolitical unrest. For example, in 2006 Typhoon Milenyo hit the Philippines and caused irrevocable damage to the Philippine national genebank (Grain, 2007). In October 2015, the first withdrawal from the seedbank was made so that researchers, at the International Centre for Agricultural Research in Dry Areas (ICARDA) in civil war-torn Aleppo in Syria could continue their studies in safe new centres in Lebanon and Morocco (CNN, 2015). ICARDA is particularly valuable as it contains seeds of crops that grow in world’s driest regions (Nature, 2015).

How is the arctic changing?

2016 was the hottest year on record as a result of climate change. This led to extreme weather globally. Svalbard and the Arctic warm up more quickly than other areas of the world and at the end of 2016 the average temperature at the site of the vault (Spitsbergen) was 7°C above normal which pushed the permafrost above melting point (The Guardian, 2017). This led to melting and heavy rain, rather than the anticipated light snow that usually falls. As a result, meltwater gushed into the 100m long entrance, which later froze to ice requiring hacking out.

The vault was designed to exist without human intervention in a worst case scenario, but it is currently being monitored 24 hours a day. Vault managers are now working to waterproof the tunnel and dig trenches into the mountain the channel meltwater and rain away. The Global Seed Vault is designed with the view that the permafrost it is encased by, is per definition, permanent. However in an increasing changing climate is this incredibly important doomsday vault safe?

Key Words

Civil War
A war between two organised groups that are part of the same state, or country

Gene bank
This is a type of repository that preserves genetic material. For example, by stocking seeds, or freezing cuttings from plants. It can also include the freezing of sperm of egg in zoological freezer

Permafrost
Permafrost is a permanently frozen layer below the Earth’s surface. It consists of soil, gravel, and sand, usually bound together by ice. Permafrost usually remains at or below 0C (32F) for at least two years.

Typhoon
A type of tropical storm that are formed over the Northwest Pacific Ocean

Lesson Ideas

Pupils can take a look at videos and images of the Global Seed Vault. What do they already know about Svalbard? Ask pupils to draw a diagram of the vault explaining its design and structure. How is this ‘impenetrable deep freezer’ provided by the environment?

Ask pupils to research either Typhoon Milenyo (2006) or the civil war in Aleppo, Syria (2015). Discuss: how important is international co-operation in dealing with natural and man-made disasters? How can we think about local, national and global scales as being interconnected by something as small as a seed? Map these connections on a world map if possible.

Consider which plants and crops pupils believe should be added to the Global Seed Bank to secure the global food supply. What are these seeds?

2016 was the hottest year on record and affected the security of the Global Seed Bank. Ask pupils to design a poster to raise awareness of vault and to encourage understanding of climate change in the Svalbard region.
