Interactions among Amazon land use, forests and climate: prospects for a near-term forest tipping point
Some model experiments predict a large-scale substitution of Amazon forest by savannah-like vegetation by the end of the twenty-first century. Expanding global demands for biofuels and grains, positive feedbacks in the Amazon forest fire regime and drought may drive a faster process of forest degradation that could lead to a near-term forest dieback. Rising worldwide demands for biofuel and mea...
متن کاملAbrupt increases in Amazonian tree mortality due to drought-fire interactions.
Interactions between climate and land-use change may drive widespread degradation of Amazonian forests. High-intensity fires associated with extreme weather events could accelerate this degradation by abruptly increasing tree mortality, but this process remains poorly understood. Here we present, to our knowledge, the first field-based evidence of a tipping point in Amazon forests due to altere...
متن کاملRoad building, land use and climate change: prospects for environmental governance in the Amazon
Some coupled land-climate models predict a dieback of Amazon forest during the twenty-first century due to climate change, but human land use in the region has already reduced the forest cover. The causation behind land use is complex, and includes economic, institutional, political and demographic factors. Pre-eminent among these factors is road building, which facilitates human access to natu...
متن کاملCerrado conservation is essential to protect the Amazon rainforest.
Despite widespread deforestation the forests of Amazonia still cover more than 5 million km and may host up to a quarter of the world’s terrestrial species (Dirzo and Raven 2003)—many of which are still undocumented. Conservation of these forests is important, not just for the biodiversity they contain, but also for the vital ecosystem services they provide. Historically, the greatest threat to...
متن کاملLand Use and Land Cover Change Dynamics across the Brazilian Amazon: Insights from Extensive Time-Series Analysis of Remote Sensing Data
Throughout the Amazon region, the age of forests regenerating on previously deforested land is determined, in part, by the periods of active land use prior to abandonment and the frequency of reclearance of regrowth, both of which can be quantified by comparing time-series of Landsat sensor data. Using these time-series of near annual data from 1973-2011 for an area north of Manaus (in Amazonas...
