Article Synopsis
- The study examines variations in anthropogenic carbon net flux estimates from land, focusing on how definitions of "managed" vs. "unmanaged" forest land influence these calculations, using global Earth Observation datasets for accuracy.
- In Brazil, from 2001 to 2020, Earth Observation (EO) data classified Brazil as a net carbon sink, while national reports indicated a net carbon source, highlighting discrepancies that can be traced back to differing methodologies and factors used in both datasets.
- Results from Indonesia showed similar estimates between EO and national reports, but Malaysia revealed significant differences in both magnitude and sign, illustrating the complexities in accurately measuring forest carbon fluxes due to lack of detailed forest type data
The Brazilian Cerrado is one of the most biodiverse savannas in the world, yet 46% of its original cover has been cleared to make way for crops and pastures. These extensive land-use transitions (LUTs) are expected to influence regional climate by reducing evapotranspiration (ET), increasing land surface temperature (LST), and ultimately reducing precipitation. Here, we quantify the impacts of LUTs on ET and LST in the Cerrado by combining MODIS satellite data with annual land use and land cover maps from 2006 to 2019.

It comprises approximately 2 million km2 and is divided into 22 ecoregions, based on environmental conditions and vegetation. The most dominant vegetation type is cerrado sensu stricto (cerrado ss), a savanna woodland.
