Abstract	Information on carbon (C) sequestration potential of agroforestry practices (AP) is needed to develop economically beneficial and ecologically and environmentally sustainable agriculture management plans. The synthesis will provide a review of C sequestration opportunities for AP in temperate North America and the estimated C sequestration potential in the US. We estimated carbon sequestration potential for silvopasture, alley cropping, and windbreaks in the US as 464, 52.4, and 8.6 Tg C yr−1, respectively. Riparian buffers could sequester an additional 4.7 Tg C yr−1 while protecting water quality. Thus, we estimate the potential for C sequestration under various AP in the US to be 530 Tg yr−1. The C sequestered by AP could help offset current US emission rate of 1,600 Tg C yr−1 from burning fossil fuel (coal, oil, and gas) by 33 %. Several assumptions about the area under different AP in the US were used to estimate C sequestration potential: 76 million ha under silvopasture (25 million ha or 10 % of pasture land and 51 million ha of grazed forests), 15.4 million ha (10 % of total cropland) under alley cropping, and 1.69 million ha under riparian buffers. Despite data limitation and uncertainty of land area, these estimates indicate the important role agroforestry could play as a promising CO2 mitigation strategy in the US and temperate North America. The analysis also emphasizes the need for long-term regional C sequestration research for all AP, standardized protocols for C quantification and monitoring, inventory of AP, models to understand long-term C sequestration, and site-specific agroforestry design criteria to optimize C sequestration.
