The incidence and importance of fire in the Amazon have increased substantially during the past decade, but the effects of this disturbance force are still poorly understood. The forest fire dynamics in two regions of the eastern Amazon were studied. Accidental fires have affected nearly 50 percent of the remaining forests and have caused more deforestation than has intentional clearing in recent years. Forest fires create positive feedbacks in future fire susceptibility, fuel loading, and fire intensity. Unless current land use and fire use practices are changed, fire has the potential to transform large areas of tropical forest into scrub or savanna.

Reducing Carbon Emission by Slowing Deforestation: Initiatives in Brazil
Brazil could make a substantial contribution to climate change mitigation. Should the UNFCCC include a "reduction of emissions from deforestation and degradation" (REDD) mechanism in its post-2012 framework? About 75 per cent of Brazil's CO2 emissions do not result...
