米国メリーランド州の3郡を対象に、カバークロップ、マルチ、不耕起、輪作、ストリップクロッピングの5つの農業GHG削減対策の費用対効果をCOMET-PlannerとUSDAのコストデータを用いて評価。カバークロップは最大の削減量（100エーカーあたり40〜71t CO2e）を示すが、削減コストは$190〜211/t CO2eと高い。ストリップクロッピングは最も費用対効果が高く、$10.04/t CO2eで24t CO2e削減。マルチは材料によりコストが大きく変動し、天然リーフマルチが$348/t CO2eと最も低い。

This study evaluates the cost-effectiveness of five agricultural GHG mitigation practices (cover cropping, mulching, no-tillage, crop rotation, strip-cropping) in three Maryland counties using COMET-Planner and USDA cost data. Cover cropping yields the highest reductions (40-71 t CO2e per 100 acres) but at high costs ($190-211/t CO2e). Strip-cropping is most cost-effective at $10.04/t CO2e with 24 t CO2e reduction. Mulching costs vary widely by material, with natural leaf mulch at $348/t CO2e and synthetic/wood chips exceeding $11,000 and $83,000/t CO2e.

📄 Abstract（原文）
Agriculture serves as both a contributor and a sink of greenhouse gas (GHG) emissions. Even though the USDA promotes climate-resilient agricultural practices, farmers face a critical challenge in identifying the most cost-effective GHG reduction strategies or practices. This study assesses the cost-effectiveness of reducing agricultural GHG emissions across five strategies- cover cropping, mulching, no- tillage, crop rotation, and strip-cropping by integrating COMET Planner with USDA NRCS cost data across three Maryland counties: Caroline, Wicomico, and Somerset. Findings reveal that cover cropping provides the highest GHG reductions, with total CO2 equivalent reductions ranging from 40 to 71 t CO2 e per 100 acres, depending on species and irrigation status. Despite these reductions, the average mitigation cost remains relatively high, ranging from $190 to $211 per t CO2e. Mulching generates consistent but smaller reductions (32 t CO₂ e per 100 acres) than cover cropping, with a wide range of cost variability across material types. Natural leaf mulch offers the lowest mitigation cost at approximately $348 per t CO₂ e, whereas synthetic materials and wood chips exceed $11,000 and $83,000 per t CO₂ e, respectively. Strip cropping emerges as the most cost-effective strategy, with CO₂ equivalent reductions of 24 t CO₂ e per 100 acres and mitigation costs as low as $10.04 per t CO₂ e. Overall, the analysis indicates significant differences in cost effectiveness across several conservation practices, with strip-cropping the most economically efficient choice, while mulching exhibits comparatively high costs relative to its GHG benefits. Cumulatively, cover cropping has been shown to reduce high amounts of GHG emissions.
