Chile’s ‘Noah’s Ark’ for Seeds Preserves Biodiversity in Arid North

Deep in the Atacama Desert of Chile, a unique facility is working to safeguard the nation’s botanical heritage. The Initihuasi Seed Bank, nestled near the town of Vicuña, is preserving plant life against potential catastrophes, including the growing threat of climate change. This effort represents a critical step in ensuring the future of Chilean agriculture and biodiversity.

A Remote Repository for Resilience

Located a few miles outside Vicuña – a town notable as the birthplace of Nobel laureate Gabriela Mistral – the Initihuasi Seed Bank is intentionally isolated. Researcher Ana Sandoval explained that the remote location is a key security measure, protecting the seeds from events like wars and other large-scale disruptions. The facility itself is built to withstand earthquakes, with thick concrete walls and a walk-in freezer maintaining a constant -4 degrees Fahrenheit and 15% humidity. Seeds are stored in aluminum pouches, a precaution against seismic activity.

Did You Know? Chile is home to 4,655 plant species, and 46% of those are found nowhere else on Earth.

Preserving a Legacy

The Initihuasi Seed Bank isn’t simply archiving existing species; it’s also working to recover those previously thought lost. Sandoval highlighted the case of a blue crocus, exported to Europe as an ornamental plant, which was rediscovered in the Andes 50 years after being declared extinct. Seeds were collected and brought to the bank for preservation. Another specimen, declared extinct at the turn of the 19th century, is also safeguarded within the facility.

The bank operates as part of a national network, with duplicates of some seeds – including bean species – sent to a facility in Colombia and maize species to Svalbard, a Norwegian archipelago in the Arctic Circle, for additional security. This collaborative approach ensures the long-term preservation of Chile’s plant genetic resources.

Expert Insight: The creation of seed banks like Initihuasi demonstrates a proactive approach to mitigating the risks posed by environmental change. By preserving genetic diversity, these facilities provide a crucial resource for adapting agricultural practices and ensuring food security in the face of unpredictable conditions.

Facing a Changing Climate

Carlos Furche, director of the national network of seed banks and a former Minister of Agriculture for Chile, described the facility as a “Noah’s Ark” for Chilean agriculture. He emphasized that global agriculture’s survival depends on its ability to adapt, and that Chile is particularly vulnerable to the effects of climate change. Furche anticipates significant shifts in environmental conditions within the coming decades, and believes the seed bank will be essential for meeting these new challenges.

Frequently Asked Questions
