The Coconut Revolution

The Coconut Revolution is a 2001 multi-award winning documentary film about the struggle of the indigenous peoples of Bougainville Island. The movement is described as the "world's first successful eco-revolution" and has drawn parallels with the conflict depicted in the 2009 film.

The movie tells the story of the successful uprising of the indigenous peoples of Bougainville Island against the Papua New Guinea army and the mining plans of the mining corporation Rio Tinto Zinc (RTZ) to exploit their natural resources. The documentary reveals how the Bougainville Revolutionary Army (BRA) managed to overcome the marine blockade strategy used by the Papuan army by using coconut oil as fuel for their vehicles.
