Guardians of Life: Indigenous Wisdom, Science and Restoring the Planet | Kiliii Yuyan | TEDxBerkeley

Key Concepts

• Traditional Ecological Knowledge (TEK)
• Indigenous stewardship and conservation
• Cultural fire/prescribed burning
• Biodiversity and its relationship to indigenous territories
• Shark sanctuaries
• Keystone species
• Dam removal and river restoration
• Community-based conservation
• Importance of indigenous voices

1. Personal Anecdote: Singing to Orcas

• The speaker recounts an experience in 2009 in the San Juan Islands, Washington, where she and friends encountered orcas.
• Her friend suggested singing to the orcas. Initially hesitant, the speaker recalled a story from her Siberian native grandmother (Dai Khuch) that orcas are relatives and will visit if sung to.
• After singing, the orcas approached their kayaks, with one even nudging a kayak.
• This experience reinforced the speaker's belief in the deep knowledge embedded in her grandmother's stories.
• She mentions a similar experience with beluga whales in the Canadian Arctic, where singing attracted the whales.

2. Indigenous Territories and Biodiversity

• Indigenous territories comprise about 40% of all remaining land on Earth and contain more biodiversity than national parks.
• This realization led the speaker to become a National Geographic photographer, focusing on stories about indigenous communities and their connection to the land.

3. Case Study: Palau - Shark Sanctuary and Coral Reef Resilience

• Palau's coral reefs have high biodiversity and are resilient to climate change due to healthy fish populations, including reef sharks.
• The indigenous Palauans were the first to declare their waters a shark sanctuary.
• Image of a black banded seasake from Palau made the cover of National Geographic's Pictures of the Year in 2023.

4. Case Study: Australia's Wet Tropics - Cultural Fire and Keystone Species

• Australia's Wet Tropics, a UNESCO World Heritage site, is experiencing a decline in biodiversity despite government protection.
• Mature rainforest is taking over, impacting species like the cassowary, a keystone species that disperses seeds.
• The Jabukai people have lived in the Wet Tropics for up to 60,000 years and have shaped the landscape using cultural fire.
• Cultural fire, unlike destructive wildfires, is a cool, slow burn that consumes leaf litter and manages the forest.
• European colonizers banned indigenous fire practices, leading to an accumulation of flammable brush and devastating wildfires.
• The return of indigenous fire is helping to restore the landscape.

5. Traditional Ecological Knowledge (TEK)

• TEK is the knowledge indigenous peoples acquire over centuries of living in their homelands, crystallized into stories and songs.
• It involves community-based monitoring of the environment.

6. Case Study: Palau - "Bul" System of Fishery Management

• Palau uses an ancient sister system of fishery management called "bul."
• If a chief determines that a fish population is declining in a certain reef, he declares a "bul," closing that reef and opening another to maintain a healthy fishery.

7. Case Study: Greenland - Narwhal Conservation and Sled Dogs

• In Greenland, TEK is written down as the world's oldest written conservation law.
• To maintain narwhal populations, Inuit must hunt traditionally in kayaks, using hand-thrown harpoons, instead of rifles and motorboats.
• Sled dogs are critical to life in North Greenland, as they don't require fossil fuels and are well-adapted to the environment.
• Greenland sled dogs are semi-domesticated and closely related to wolves.

8. Case Study: Klamath River - Dam Removal and River Restoration

• Dams built on the Klamath River in the early 1900s blocked salmon and spread disease.
• A salmon-killing parasite thrived in the dammed river, decimating the salmon population.
• The Karuk and Yurok peoples fought for 30 years to remove the dams.
• Their efforts led to the largest dam removal project in history.
• By the summer of 2024, all the dams were down, and the river began to restore itself.

9. Case Study: Amazon Rainforest - Kofan People and Oil Drilling

• The Amazon rainforest is primarily indigenous land.
• The Kofan people in Ecuador have the highest biodiversity in any single region on Earth.
• Kofan leader Ugo Lucatante was sent to Seattle to gain a Western education and return to fight for his people.
• The Kofan fought against oil drilling for 50 years, becoming role models for conservation in Latin America.

10. Key Arguments and Perspectives

• The most beautiful and intact lands are beautiful because of their people, not in spite of them.
• Indigenous stewardship is essential for conservation.
• Traditional Ecological Knowledge (TEK) is a valuable resource for understanding and managing ecosystems.
• Conservation efforts should recognize and support the hard labor of indigenous communities.

11. Notable Quotes

• Madzle Christensen (Greenland): "Hunters are seeking balance that is why we take care of our place we are the balance that is why we're hunters."
• Ranger Toppsy Gibson (Australia): "Cultural fire is a very big thing...fire brings more wabes down to the beach and other little creatures it brings back that soft grass for them to eat."
• Ugo Lucatante (Amazon): "If the world truly wants to protect its forests then efforts like ours need to be recognized for what they are the hard labor of people who must also feed their families and raise their children."
• Lisa Hillman (Klamath River): "This land belongs to you you belong to this land so you must care for it."

12. Synthesis/Conclusion

The speaker emphasizes the critical role of indigenous communities in conservation and biodiversity preservation. Through personal anecdotes and case studies from around the world, she demonstrates the effectiveness of Traditional Ecological Knowledge (TEK) and the importance of supporting indigenous stewardship. The removal of dams on the Klamath River, the shark sanctuary in Palau, and the cultural fire practices in Australia are powerful examples of how indigenous-led initiatives can restore ecosystems and protect biodiversity. The speaker concludes by urging recognition and support for the hard work of indigenous peoples in protecting the world's most valuable natural resources.
