• Perenco, a London-based oil and gas firm, is being sued by Peru’s 350,000-strong native Indian community over plans to bring its chainsaws, incinerators and heavy-lifting equipment into “Lot 67,” a vast, secluded area of the Marañon basin near Peru’s border with Ecuador. The company wants to establish whether the region has exploitable oil reserves. But rooting around in the area may also result in the Pananujuri and Taromenane tribes, who are said to inhabit the jungle’s deepest reaches, coming into contact with outsiders for the first time.
