In the Brazilian Amazon, indigenous peoples hold a significant portion of the local forest. Their Lands as a whole cover approximately 110 million hectares and contain about 30% of forest carbon in the region, which corresponds to something around 13 billion tons of carbon. This is equivalent to about a year of global emissions of greenhouse gases (GHG). These territories play a key role in stopping the encroachment of deforestation in the region. Therefore, they play an extremely important role in the conservation of biodiversity and to achieve the GHG emissions reduction targets undertaken by Brazil through the law that established the National Policy on Climate Change (PNMC, Law n° 12,187/2009).
Natural and drought scenarios in an east central Amazon forest: Fidelity of the Community Land Model 3.5 with three biogeochemical models
Recent development of general circulation models involves biogeochemical cycles: flows of carbon and other chemical species that circulate through the Earth system. Such models are valuable tools for future projections of climate, but still bear large uncertainties...
