Changes in Carbon Dioxide Balance Associated with Land Use and Land Cover in Brazilian Legal Amazon Based on Remotely Sensed Imagery

The Amazon region comprises the largest tropical forest on planet and is responsible for absorbing huge amounts of CO2 from atmosphere. However, changes in land use cover have contributed to an increase greenhouse gas emissions, especially CO2, endangered indigenous lands protected areas region. objective this study was detect emissions removals associated with Brazilian Legal (BLA) through analysis multispectral satellite images 2009 2019. Gross Primary Production (GPP) CO2Flux variables were estimated by MODIS sensor onboard Terra Aqua satellite, representing carbon absorption vegetation during photosynthesis process. Atmospheric concentration GOSAT satellite. GPP showed effective flux BLA atmosphere, which weakly correlated precipitation (r = 0.191 0.133). absorbed 211.05 TgC annually but, due its partial conversion other uses, loss 135,922.34 km2 area resulted 5.82 less being absorbed. Pasture agriculture, comprise main conversions, increased 100,340.39 1.32 3.19 less, emitted close twice more, than these areas. concentrations 2.2 2.8 ppm BLA, hotspots observed southeast Amazonia, capture over years, mainly after 2013, north west BLA. This brings light dynamics, models, as related one biggest world reservoirs, Amazon, also important fulfillment international agreements signed Brazil reduce biodiversity conservation ecosystem services
