Deforestation-Induced Fragmentation Increases Forest Fire Occurrence in Central Brazilian Amazonia

Agricultural intensification increases deforestation fire activity in Amazonia

Fire-driven deforestation is the major source of carbon emissions from Amazonia. Recent expansion of mechanized agriculture in forested regions of Amazonia has increased the average size of deforested areas, but related changes in fire dynamics remain poorly characterized. We estimated the contribution of fires from the deforestation process to total fire activity based on the local frequency o...

Fire and deforestation dynamics in Amazonia (1973–2014)

Consistent long-term estimates of fire emissions are important to understand the changing role of fire in the global carbon cycle and to assess the relative importance of humans and climate in shaping fire regimes. However, there is limited information on fire emissions from before the satellite era. We show that in the Amazon region, including the Arc of Deforestation and Bolivia, visibility o...

Deforestation and Forest Fragmentation in the Amazon

Deforestation in Amazonia impacts riverine carbon dynamics

Fluxes of organic and inorganic carbon within the Amazon basin are considerably controlled by annual flooding, which triggers the export of terrigenous organic material to the river and ultimately to the Atlantic Ocean. The amount of carbon imported to the river and the further conversion, transport and export of it depend on temperature, atmospheric CO2, terrestrial productivity and carbon sto...

Deforestation in the Brazilian Amazonia and Spatial Heterogeneity: a Local Environmental Kuznets Curve Approach

There is a concern about the increasing pressure over the forest as economic growth increases. As for the Brazilian Amazon deforestation, there are noticeable intra-regional differences due to its occupation history, extensive area, economic structure and geographical aspects, inducing a strong spatial heterogeneity in this environmental phenomenon. This paper investigates locally the Environme...
