Conteúdo:	Prediction of soil organic carbon (SOC) stocks, tree carbon stocks, enteric emissions, and beef production is essential for evaluating low-carbon livestock systems. However, there is still limited information regarding the use of mechanistic models capable of simultaneously integrating these components under tropical integrated production systems. This study evaluated the performance of the Manure-DeNitrification-DeComposition (Manure-DNDC) model to simulate SOC stocks and estimate the emission intensity of beef production in integrated crop-livestock-forest (ICLF) systems of the Brazilian Cerrado. Methods: Experimental data collected from 2008 to 2016 at the Embrapa Beef Cattle experimental site in Campo Grande, Mato Grosso do Sul, Brazil, were used to evaluate native vegetation (NV), integrated crop-livestock (ICL), and integrated crop-livestock-forest systems (ICLF14 and ICLF22). The Manure-DNDC model was applied to simulate SOC dynamics, beef production, and enteric emissions, and model estimates were compared with measured field data. Results: The model showed good agreement between simulated and measured SOC stocks, beef production, and enteric emissions across the evaluated systems. Annual additional SOC stocks were estimated at -0.025 Mg CO2e ha-¹ year-¹ for NV, +1.06 Mg CO2e ha−¹ year-¹ for ICL, +0.83 Mg CO2e ha-¹ year-¹ for ICLF22, and +0.30 Mg CO2e ha-¹ year-¹ for ICLF14. Emission intensity was estimated at 7.7 kg CO2e kg-¹ live weight gain (LWG) for ICL, whereas negative net values were observed for ICLF22 (-31.5 kg CO22 kg-¹ LWG) and ICLF14 (-69.5 kg CO2e kg-¹ LWG).Discussion: The Manure-DNDC model satisfactorily represented greenhouse gas (GHG) emissions and carbon sequestration under Brazilian Cerrado conditions. The findings highlight the potential of ICLF systems to mitigate GHG emissions and reduce the carbon footprint of beef production.
