The plots were classified into three agroforestry designs: D1 (shade trees -coffee on slopes), D2 (shade trees -coffee-banana on slopes), and D3 (shade trees -coffee-banana in the valley). The CO2Fix model was used to simulate the total C stocks at a fifty-years projection under the baseline and climate change scenarios in the three agroforestry designs with coffee.<span class="CharOverride-8">&nbsp;<strong>Results.</strong>&nbsp;</span>The total C in the baseline was 124.59, 107.43, and 102.320 t ha<sup><span class="CharOverride-4">-1</span></sup>&nbsp;for D1, D2, and D3, respectively. There were decreases between 0,77 and 8,75 t ha<sup><span class="CharOverride-4">-1</span></sup>&nbsp;in the low total C stocks under climate change scenarios in the three agroforestry designs evaluated. There were no statistically significant differences between agroforestry designs in the baseline and under climate change scenarios. Although variations were found, total C stocks were maintained over time. The tree cohort was the main storage source of total C storage.<span class="CharOverride-8">&nbsp;<strong>Conclusion.&nbsp;</strong></span>It was possible to simulate, in a fifty-year projection, the carbon stocks in aboveground biomass and soil in the baseline, under different climate change scenarios, using the CO2Fix model, in agroforestry systems with coffee from the Catuai Amarillo S. de S.S. Society.</p> ER -
