Anais do XIX Simpósio Brasileiro de Sensoriamento Remoto

The regrowth of vegetation in previously deforested areas in the Brazilian Amazon plays an important role in the global carbon cycle, functioning as a dynamic carbon sink. Here, we used multi-temporal post-deforestation land cover trajectories and RADAR-derived above ground biomass (AGB) maps to quantify the patterns of biomass accumulation at different stages of vegetation regeneration in the Brazilian Amazon for the years 2008 and 2010. Our results showed that the combination of trajectories based on TerraClass product with AGB maps was consistent for tracking AGB changes across the Brazilian Amazon, showing the potential biomass increase across the regeneration process. Although the dynamics of the regeneration process can be interpreted in relation to Shrubby pasture, Regeneration with pasture and Secondary vegetation classes, the amount of accumulated biomass by them will depend on the previous class and the regeneration time.
