“The fire that we’re seeing today is a fire that’s directly related to deforestation,” Ane Alencar, the scientific director of Brazilian NGO IPAM (Institute of Environmental Research in Amazonia), told forest news website Mongabay. These are not wildfires, she said, but rather fires set by people seeking to create cattle ranches, intentionally ignited during the dry season each year. “They cut the trees, leave the wood to dry and later put fire to it, so that the ashes can fertilize the soil.”

As Brazilian president Jair Bolsonaro has expressed disdain for conserving the rainforest, his support for industrial growth has reportedly encouraged ranchers and other developers to move more brazenly into undeveloped forest land—much of which is indigenous territory.

Research has shown that indigenous management practices are the
