英文摘要	Silvopastoral systems (SPS) offer both environmental and economic benefits, including climate change mitigation through carbon sequestration. Important features are tree density and animal stock rate. The objective of this study was to evaluate the long-term trajectory of sustainable livestock carrying capacity and carbon budget developing an Agent-Based Model (ABM) for an SPS. The ABM outputs the performance of animal growth, forage, and trees in several scenarios over 10-year periods. Rotational grazing and forestry presence in paddocks allowed the achievement of a balance among forage availability, cattle demand and trees. The model fit very well in predicting Live weight gain and Live weight (LW) for cattle. The average length of fattening cycles was 258 +/- 24 days, and an annual yield of LW exported of the system of 98.7 +/- 2.6 kg ha-1. A balance of carbon-neutral or marginally positive in beef production was achieved with a ratio of 380 steers at a 606-ha grazing area with 13% forested surface. Estimated carbon emission exhibited an inverse exponential relationship with weight gain. The average emission was 24.9 kg of CO2e per unit of LWG, for an average gain of 0.388 kg animal-1 day-1. The ABM is a valuable tool for understanding the complexity of these systems, generating emergent properties. The results revealed a conflict between the economic-productive and the environmental dimension. So as to achieve a neutral carbon system, it is necessary to maintain a lower number of livestock heads than the property's potential (0.72 vs 0.79 livestock units per hectare). Future research should include economic and other environmental variables in the model.
