Net forest-related greenhouses gas flux represents the net exchange of greenhouses gas between forests and the atmosphere between 2001 and 2020. This net flux layer is part of the forest carbon flux model described in Harris et al. (2021). Here, the average annual net fluxes in MtCO₂e is shown at global level and the average annual net fluxes in MtCO₂e/ha in protected areas and outside protected areas at national level.
The researcher estimated the Net Forest Carbon Flux calculating the balance between carbon emitted and sequestered by forests during the last 20 years (2001-2020). Negative values are found where forests sequestered more carbon from the atmosphere than what they emitted and positive values are found where emissions from stand-replacing forest disturbances were higher than removals. Emissions include all relevant ecosystem carbon pools (aboveground biomass, belowground biomass, dead wood, litter, soil) and greenhouse gases (CO2, NH4, N2O) while removals are into the aboveground and belowground biomass pools.
