日本語

本レビューは、熱帯地域における統合作物・家畜・森林（ICLF）システムの樹木構成要素に焦点を当て、木材生産、材質、温室効果ガス（GHG）緩和、生態系機能に関する知見を統合している。適切に管理された樹木は炭素隔離を高め、CH4やN2O排出を相殺し、土壌・生物多様性・農場収益性を改善する。導入は技術的・経済的制約に直面するが、ブラジルのABC+計画やNDC達成に貢献し得る。

English

This review synthesizes knowledge on the tree component of Integrated Crop–Livestock–Forest (ICLF) systems, focusing on wood production, timber quality, GHG mitigation, and ecosystem functioning in tropical environments. Well-managed trees enhance carbon sequestration, offset CH4 and N2O emissions, and improve soil, biodiversity, and farm profitability. Adoption faces technical and economic barriers, but optimized silviculture supports Brazil's ABC+ Plan and NDC targets.

📝 gxceed 編集解説 — Why this matters

日本のGX文脈において

ブラジル農業由来のGHG削減策に関する知見であり、日本のGX文脈（SSBJ・有報・Scope3）との直接接続は弱い。ただし、サプライチェーン上流の土地利用・農業排出（Scope3カテゴリ1）を評価する日本企業にとって、炭素隔離型農業の実装可能性を理解する参考資料となる。

In the global GX context

This paper contributes to the global literature on agricultural GHG mitigation and nature-based carbon sequestration, relevant to land-use and Scope 3 Category 1 accounting under GHG Protocol and emerging ISSB/CSRD disclosure of land-sector emissions. It offers empirical grounding for tropical agroforestry as a mitigation pathway, though it does not engage directly with TCFD/ISSB disclosure frameworks.

👥 読者別の含意

🔬研究者:熱帯ICLFシステムにおける樹木管理と炭素・GHG収支の関係を整理したレビューとして、土地利用排出モデリングやScope3算定研究の基礎資料になる。

🏢実務担当者:農産物・林産物を調達する企業が、サプライチェーン上流の炭素隔離型農業の可能性と制約を把握する際に参考となる。

🏛政策担当者:ブラジルABC+計画のような農業気候政策の設計において、樹木構成要素の多機能性と導入障壁を踏まえた支援策の検討に資する。

📄 Abstract（原文）

Integrated Crop–Livestock–Forest (ICLF) systems have emerged as a key strategy for sustainable agricultural intensification by simultaneously enhancing productivity, ecosystem services, and climate resilience in tropical environments. This review synthesizes current knowledge on the role of the tree component in ICLF systems, with emphasis on wood production, timber quality, greenhouse gas (GHG) mitigation, and ecosystem functioning. We discuss the conceptual basis and typologies of ICLF systems, the influence of spatial and temporal arrangements, and the biotic and abiotic factors regulating tree growth and productivity. The review further examines management practices—including species selection, tree density, thinning, and pruning—and their implications for wood yield, timber quality, and overall system performance. Evidence demonstrates that appropriately managed tree components enhance nutrient cycling, soil quality, biodiversity, animal welfare, and farm profitability while increasing carbon sequestration in aboveground biomass and soils. Trees also contribute to offsetting methane (CH4) and nitrous oxide (N2O) emissions, reinforcing the climate mitigation potential of ICLF systems. Despite these benefits, adoption remains constrained by technical, economic, and regional challenges, highlighting the need for site-specific recommendations and improved silvicultural management. Overall, optimizing the tree component can maximize the multifunctionality of ICLF systems, supporting sustainable wood production, ecosystem restoration, the implementation of Brazil’s ABC+ Plan, and the achievement of the country’s Nationally Determined Contributions (NDCs) under the Paris Agreement.
