Conventional agriculture is a significant driver of ecosystem service loss. In contrast, agroforestry is a land use option that can restore ecosystem services, such as carbon sequestration. Using field data from small proprieties we aimed to quantify carbon sequestration and its potential economic impact in coffee agroforestry systems (CAS) in Brazil. Allometric equations were used to estimate carbon stock and tree biomass, while net present value (NPV), internal rate of return (IRR), and payback period were used as economic feasibility parameters in a 16-year modeled scenario. Discount rate and carbon price applied was 6% and US$ 5.1 Mg CO₂e^-1, respectively. Total mean carbon stock in two years old and 16 years old CAS were 1.38 ± 0.63 Mg C ha^-1 and 59.69 ± 32.63 Mg C ha^-1, respectively. All CAS presented payback periods of two years, with a mean NPV of US$ 50,585.91 and a mean IRR of 89.93%. Carbon revenue impact on NPV and IRR was US$ 148.80 and 0.24%, respectively. Our results indicate that carbon sequestration economic impact does not encourage the adoption of coffee agroforestry systems. However, these systems can be an economically viable land use option that sequester large amounts of carbon comparable to forest patches.

常规农业是生态系统服务损失的重要驱动力。相反，农林业是一种土地使用选择，可以恢复生态系统服务，例如固碳。我们使用小规模的实地数据来量化碳固存及其对巴西咖啡农林业系统（CAS）的潜在经济影响。在16年的模拟情景中，使用了等速方程来估算碳储量和树木生物量，而将净现值（NPV），内部收益率（IRR）和投资回收期用作经济可行性参数。贴现率和碳价格分别为6％和5.1 Mg CO ₂ e ^-1美元。2岁和16岁CAS的总平均碳储量为1.38±0.63 Mg C ha ^-1和59.69±32.63 Mg C ha ^-1。所有CAS的投资回收期均为两年，平均NPV为50,585.91美元，内部收益率平均为89.93％。碳收入对净现值和内部收益率的影响分别为148.80美元和0.24％。我们的结果表明，碳固存的经济影响并不鼓励采用咖啡农林业系统。但是，这些系统可能是一种经济上可行的土地使用选择，与森林斑块相比，其固存了大量的碳。
