Brazil's Bolsonaro unveils bill to allow commercial mining on indigenous land

• Move by far-right president was a campaign promise
• Bolsonaro expects 'pressure from environmentalists'
• 'Genocide' fears for isolated tribes as ex-missionary named to head Brazil agency

Brazil's far-right president, Jair Bolsonaro, unveiled a controversial bill on Wednesday that would allow commercial mining on protected indigenous lands, delivering on a campaign promise that has shocked tribal leaders and environmentalists.

The bill to regulate mining including oil and gas projects, as well as hydroelectric dams, on indigenous reservations for the first time, will be sent to congress this week. Brazil's constitution currently does not rule out mining on reservations, but does not allow it because it has not been regulated.
