El segundo objetivo busca iniciar una discusión acerca de las implicaciones que tienen para la biodiversidad los diferentes patrones de la fragmentación forestal.

El artículo busca también extender la literatura sobre las carreteras para tomar en cuenta los procesos sociales y conductas individuales que crean la arquitectura de la red vial. Las carreteras impactan al cambiar la cobertura de la tierra en todas partes, y es bien conocido su papel en la deforestación amazónica. El primer objetivo del artículo es ampliar el debate sobre la fragmentación, abocando los procesos sociales que la generan gracias a la construcción de carreteras. This is accomplished through 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.Įste artículo versa sobre el surgimiento de redes viales y la fragmentación de la selva en la Amazonia Central, región que ha sido afectada por igual por asentamientos espontáneos y planeados. The article pursues its objectives by implementing a conceptual framework that extends the pattern-to-process paradigm of landscape ecology by adding a (social) process-to-pattern component. Our specific focus is the geometry of settlement associated with urban nodes, referred to here as radial fragmentation. The second objective is to open a discussion about the biodiversity implications of different patterns of forest fragmentation.

The article also seeks to extend the literature on roads to address the social processes and individual behaviors that create the road network architecture. Roads impact land cover change worldwide, and their role in Amazonian deforestation is known. The first objective of the article is to broaden the discussion of fragmentation by addressing social processes that generate it through the construction of roads.

This article addresses the emergence of road networks and forest fragmentation in Central Amazônia, which has been impacted by both spontaneous and planned settlement.
