本研究はブラジルを対象に、統合的農業・アグロフォレストリーシステム（IS/AS）の気候変動緩和への貢献を統合評価モデル（BLUES）で分析。11の地域固有のIS/ASシステムを明示的にモデル化し、従来の慣行より経済的・戦略的に優位であることを示す。1.5°Cシナリオでは、メタン・亜酸化窒素の排出削減、炭素隔離の加速、大規模な炭素回収・貯蔵（CCS）や再森林化の必要性を低減し、食料・バイオエネルギー生産を確保する。
English
This study uses the Brazilian Land Use and Energy System (BLUES) integrated assessment model to evaluate the contribution of integrated agricultural and agroforestry systems (IS/AS) to land-use dynamics and climate mitigation in Brazil. Eleven region-specific production systems are modeled, showing that IS/AS are economically viable and strategically superior to conventional practices. Under 1.5°C-consistent scenarios, they substantially reduce agricultural emissions and enhance carbon sequestration while minimizing the need for CCS, reforestation, and pasture recovery, thus securing food and bioenergy production. IS/AS are foundational for sustainable land-use strategies.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では農地・森林の統合管理が注目されているが、本論文はブラジルの大規模な劣化農地での知見を提供。日本の農林業におけるカーボンファーミングやJ-クレジット制度への示唆があるが、直接的な政策連動は限定的。それでも、統合的農業システムの気候変動緩和ポテンシャルを定量的に示した点は、日本の農林業政策にも参考になる。
In the global GX context
This paper provides a detailed, region-specific modeling of integrated agroforestry systems in Brazil, demonstrating their strategic role in climate mitigation while reducing land-use competition. Globally, it offers a benchmark for nations with extensive degraded agricultural landscapes, such as those in the tropics, and supports the inclusion of such systems in Nationally Determined Contributions (NDCs). It also highlights the potential to offset the need for expensive CCS technologies.

📄 Abstract（原文）
Integrated and agroforestry systems (IS/AS) are increasingly recognised as pivotal pathways to reconcile agricultural productivity, ecosystem services, and climate mitigation. This study assesses the system-level contribution of IS/AS to land-use dynamics and greenhouse gas mitigation in Brazil using the Brazilian Land Use and Energy System (BLUES) integrated assessment model (IAM). Distinct from previous global assessments, we developed and explicitly represented eleven region-specific IS/AS production systems – two Integration-Livestock-Forest (ILF) systems, five Integration-Crop-Livestock (ICL) systems, two Integration-Crop-Livestock-Native Forest (ICLFn) systems and two Integration-Crop-Livestock-Commercial Forestry (eucalyptus/pine) systems – to capture heterogeneous productivity, input intensity, and carbon dynamics across diverse biomes. Our findings demonstrate that IS/AS are not only economically viable but also strategically superior to conventional practices, with their large-scale deployment primarily driven by their systemic expansion potential rather than marginal costs. Under 1.5°C-consistent scenarios, IS/AS substantially abate agricultural emissions, particularly methane (22 MtCO 2 e) and nitrous oxide (35 MtCO 2 e), while accelerating carbon sequestration in soils and biomass (15 MtCO 2 e). Crucially, their adoption alleviates land-use competition by minimising the need for extensive industrial carbon capture and storage (CCS), reforestation and pasture recovery – reductions of 86, 216 and 439 MtCO 2 e, respectively – thereby securing food and bioenergy production. These results underscore the role of IS/AS as foundational structural components of sustainable land-use strategies, providing a benchmark for climate policy in nations with extensive degraded agricultural landscapes.
