7. Accounting for Erosion: More complexity
Problem: The Department is planning to force soil carbon methodology proponents to measure the impact of erosion and deposition on the calculation of on-farm abatement. “How could erosion/deposition be included in the abatement calculation?” Erosion (and hence deposition) is caused by soil being exposed to the elements. Soil carbon cannot be accumulated when earth is bare. Thus it can be assumed that there will be an inverse correlation between soil erosion (reductions) and soil carbon (increases). The good carbon farmer receives topsoil from paddocks of poor farmers. It would add unnecessary complexity to try to calculate the soil trading account. (See APPENDIX D) Practical solution: Abandon the requirement to track erosion and deposition and account for it in carbon accounting on farm. It would be conservative to do so.
