             abstract = "Forest degradation is widespread around the world, due to multiple 
                         factors such as unsustainable logging, agriculture, invasive 
                         species, fire, fuelwood gathering, and livestock grazing. In the 
                         Brazilian Amazon forest degradation from August 2006 to July 2016 
                         reached 1,1 869 800 ha. The processes of forest degradation are 
                         still poorly understood, being a missing component in 
                         anthropogenic CO(2)emission estimates in tropical forests. In this 
                         work, we analyzed temporal trajectories of forest degradation from 
                         August 2006 to July 2016 in the Brazilian Amazon and assessed 
                         their impact on the regional carbon balance. We combined the 
                         degradation process with deforestation-related processes 
                         (clear-cut deforestation and secondary vegetation dynamics), using 
                         the spatially-explicit INPE-EM carbon emission model. The 
                         trajectory analysis showed that 13% of the degraded area ended up 
                         being cleared and converted in the period and 61% of the total 
                         degraded area experienced only one event of degradation throughout 
                         the whole period. Net emissions added up to 5.4 GtCO(2), 
                         considering the emissions from forest degradation and 
                         deforestation, absorption from degraded forest recovery, and 
                         secondary vegetation dynamics. The results show an increase in the 
                         contribution of forest degradation to net emissions towards the 
                         end of the period, related to the decrease in clear-cut 
                         deforestation rates, decoupled from the forest degradation rates. 
                         The analysis also indicates that the regeneration of degraded 
                         forests absorbed 1.8 GtCO2 from August 2006 and July 2016-a 
                         component typically overlooked in the regional carbon balance.",
