Dear Authors:
Thank you for providing your reply to the referee comments and a short comment. The two referees evaluated that your manuscript has good scientific significance and fair to good quality, and also, I agree with the significance of this research topic that can gather interdisciplinary interests. You gave detailed comments how the manuscript can be revised from the original one. Especially, your justification and modification on the use of emulator, with supplementary figures, look enough convincing. After revision as described in your comments, the manuscript would be reconsidered. I look forward to receiving it.

Dear Authors:
Thank you for providing the revised manuscript with comprehensive reply comments. I confirmed that the manuscript has been greatly improved from the previous form, including the re-calibration of parameters in response to referee’s concern. Although the model-based study was technically challenging (i.e., use of vertical discretization in the emulator), the authors achieved a convincing assessment on the impact of soil erosion on global carbon cycle. Finally, I recommend that the manuscript is acceptable for publication.
