Resumo: The objective of this study was to estimate the carbon balance in two silvopastoral systems (SPS) for rearing dairy heifers: Eucalyptus and african-mahogany based. Emissions of GHG were calculate based on IPCC protocols. Carbon stocks in trees were estimated through allometric equations and local references and the estimation of carbon storage in the forest component considered only the wood for solid products and the root system, while the biomass of the root system of the pasture was considered as a carbon pool as well. The net carbon balances of the silvopastoral systems were -137.18 Mg CO2e ha?1 and -47.54 Mg CO2e ha?1 for eucalyptus-based SPS and african-mahogany based SPS, respectively, showing the potential of both systems for mitigating climate change.
