本研究はメキシコ熱帯地域の単作放牧（MC）と森林放牧（SP）の炭素フットプリントと炭素隔離を比較した。結果、SPはMCよりも総合的な炭素フットプリントが低く、土壌炭素隔離が高いことを示した。この成果は熱帯放牧システムの気候変動対策に貢献する。
English
This study compares the carbon footprint and soil carbon sequestration of monoculture (MC) and silvopastoral (SP) beef cattle systems in the Mexican tropics using LCA per ISO 14067. Results show SP has a lower carbon footprint overall despite higher emissions, due to greater soil carbon sequestration, and lower variability. Findings inform climate policies for tropical grazing systems.

日本のGX文脈において
日本では熱帯畜産は主流ではないが、牛肉輸入に伴うスコープ3排出評価やJ-クレジットの農業分野での応用に示唆を与える。また、LCA手法は日本の畜産システムにも適用可能。
In the global GX context
This study provides empirical LCA data for tropical livestock systems, relevant to global carbon footprinting standards (e.g., ISO 14067) and climate mitigation in agriculture. It highlights the potential of silvopastoral systems for carbon sequestration, which could inform supply chain decarbonization strategies for companies sourcing beef from tropical regions.
👥 読者別の含意
🔬研究者:Provides comparative LCA data on carbon footprint and sequestration in tropical cattle systems, useful for methodology development and cross-system comparisons.
🏢実務担当者:Demonstrates that silvopastoral systems can reduce carbon footprint compared to monoculture, offering a practical option for beef producers seeking lower emissions.

📄 Abstract（原文）
Advancing sustainable beef systems requires understanding the carbon footprint of livestock production. Mexico is responsible for high greenhouse gas (GHG) emissions from the livestock sector, an activity that extends across large areas of land in its tropical region. This study aimed to assess the contributions of two cattle grazing systems to climate change and to their carbon (C) sequestration potential, as well as to estimate their GHG balance. The analysis was conducted in accordance with the ISO 14067 standard based on the Life Cycle Assessment methodology. The “cradle-to-farm gate” approach was applied to evaluate the carbon footprint of 1 kg of live weight of calf, including C sequestration in two beef cow-calf grazing systems in the Mexican tropics: monoculture (MC) and silvopastoral (SP). Data collected from six cattle ranches (three monoculture and three silvopastoral), in the State of Yucatán, Mexico, were used. The system boundaries included pasture, feed supplements, agrochemicals, fossil fuels, electricity, and pesticides. The potential soil C equestration was estimated from the Ex-Ante Carbon-balance Tool version 9 of the Food and Agriculture Organization of the United Nations. The results revealed that MC systems exhibited lower GHG emissions than the SP, while soil C equestration was higher in the SP. The carbon balance shows a lower carbon footprint for the SP than the MC system, and the uncertainty analysis demonstrates that the SP system had lower variability than the MC. The outcomes of this study could be used to direct policies aimed at reducing the contribution of tropical grazing systems to climate change.
