Explosive Growth of Secondary Roads from Industrial Logging

Forest loss - (Secondary) roads from industrial logging fragment ecosystems (ChatGPT)

New roads in forest frontiers enable secondary roads that amplify human impacts. Roads are key proximate drivers of environmental impacts, including forest fragmentation.

"Tropical forests face widespread environmental threats from road expansion. Previous research established that roads enable human incursion, break up ecosystems, and intensify deforestation through land clearing, fires, and illegal resource extraction. The role of secondary roads in amplifying these effects has remained poorly quantified, leading to gaps in environmental impact assessments and conservation strategies.
Environmental impact assessments failed to account for the full scale of road-induced deforestation. " (source)

"In the tropics and beyond, roads are key proximate drivers of environmental impacts, including forest fragmentation. These secondary roads in turn can dramatically elevate forest and biodiversity losses."
