pigrabbitbear writes "Farming, logging, and strip mining has long altered much of the Amazon rainforest, with slash-and-burn land-clearing techniques turning large portions of the forest into patchworks of pastures, second-growth forest, and degraded land. Now, rural people are increasingly moving to booming Amazonian cities; paradoxically, the land they're leaving behind is being ravaged by wildfires. A new paper published in PNAS shows that in the Peruvian Amazon, land use changes and depopulation have let large wildfires fly through converted land. It puts a damper on those optimistic that the urbanization of the Amazon may allow parts of the forest to recover, by centralizing populated areas and leaving old converted land to be slowly gobbled up by the encroaching forest."
