The Raposa Serra do Sol Indigenous reserve in Brazil’s Roraima state covers 1.75 million hectares (4.32 million acres) along the nation’s border with Venezuela and Guyana. It is home to 26,705 Indigenous people.
The territory has been under pressure from invaders for decades, even after being demarcated in 2005. But illegal incursions are reaching a new peak now, with an estimated 2,000 to 5,000 gold miners operating in the reserve.
Incendiary speeches by Brazilian President Jair Bolsonaro have emboldened the miners, say experts, while attempts to crackdown on wildcat mining in the Yanomami Territory in the Amazon rainforest may have pushed illegal miners operating there into the Cerrado savanna where most of Raposa Serra do Sol is located.
