本稿は、ドイツ・バイエルン州の酪農システムを対象に、泥炭地の再湿潤と鉱質土壌での飼料生産強化による温室効果ガス排出削減の可能性を評価した。再湿潤により泥炭地からの排出は約84%削減され、製品カーボンフットプリントは14-53%低減されるが、泥炭地面積割合が21.8%を超える農場では生産減少が生じる。地域スケールでは、強化生産による余剰飼料が再湿潤による不足を補えることを示した。政策支援としてEU共通農業政策の活用を提案している。
English
This study combines LCA with LandscapeDNDC to assess GHG mitigation in Bavarian dairy farms through peatland rewetting and intensified forage production on mineral soils. Rewetting reduces peatland emissions by 84% and product carbon footprint by 14-53%, but a threshold of 21.8% peatland share exists beyond which farms face production deficits. At regional scale, forage surplus from intensification outweighs deficits by nearly twofold, though increased nitrogen losses must be managed. The authors recommend EU CAP payments to incentivize this transition.

本稿はドイツの泥炭地酪農を対象とするが、土地利用転換によるCO2削減と生産性維持のトレードオフ分析は、日本における水田や湿地の保全と農業生産の両立にも示唆を与える。EU共通農業政策の活用提案は、日本の農業環境政策にも参考となる。
In the global GX context
This paper contributes to the literature on agricultural GHG mitigation, particularly the role of peatland rewetting. It provides a quantitative framework for assessing trade-offs between emissions reductions and food production, which is relevant for national climate plans and LULUCF accounting. The findings are applicable to other regions with peatland agriculture, such as Northern Europe, Indonesia, and Southeast Asia.

📄 Abstract（原文）
Peatland rewetting is crucial for Germany to achieve net greenhouse gas (GHG) neutrality by 2045 as it can help to drastically reduce emissions in the LULUCF sector. This study combines farm-level Life Cycle Assessment with the biogeochemical model LandscapeDNDC to evaluate three different Bavarian dairy farm systems with varying peatland shares, quantifying GHG mitigation potential of rewetting and associated trade-offs in forage production. Rewetting reduces peatland emissions by about 84%, lowering total product carbon footprint by 14-53%. However, a biophysical compensation failure threshold (X crit ) is identified at a peatland share of 21.8 %. Farms below this threshold can maintain forage production by intensifying mineral soils, while those exceeding it, such as high peat share farms (40% peatland), face structural shortfalls and can realistically rewet only half of their peatland area without production losses. At regional scale, a circular solution appears biophysically feasible. Aggregated results for the Ammer region indicate that the potential forage surplus from intensification on mineral soils exceeds deficits associated with peatland rewetting by nearly two-fold, while additional emissions from intensified production and increased transport remain small relative to mitigation gains. Practical implementation, however, needs to manage increased nitrogen losses on intensified mineral soils and account for site-specific socio-economic constraints. Realizing this transformation requires EU Common Agricultural Policy payments to incentivize regional cooperation and address associated socio-economic implications of transitioning away from drained peatland use, providing the necessary framework for integrating alternative land-use and restoration goals.
