Description :
This article discusses the emergence of road networks and forest fragmentation in Central Amazônia. It implements a mixed-method approach including (1) field-based narratives of the social processes that gave rise to radial fragmentation in the hinterland of the town of Itaituba, an important settlement in the middle Tapajós valley; (2) remote sensing of the evolution of road networks, which we then link to deforestation in a temporal analysis of emergent fragmentation patterns; and (3) computational applications to compare the biodiversity implications of radial and fishbone landscape fragmentation.
