本論文は、バイオ燃料持続性や森林減少評価を左右する世界土地利用モデルGTAP-BIOとGLOBIOMを、経済構造・間接土地利用変化・炭素会計・不確実性・再現性・環境正義の観点から批判的に比較する文献レビューである。7つの論点を示し、モデル選択がグローバルサウスの小農・先住民に不均等な影響を与えうると指摘。シナリオ調和や不確実性開示、参加型評価を含む「透明で公正な環境モデリング枠組み」を提案する。
English
This critical review compares GTAP-BIO and GLOBIOM, two global land-use models shaping biofuel, deforestation and climate assessments, across model architecture, indirect land-use change, carbon accounting, uncertainty and environmental justice. Drawing on 2020-2026 literature and cases from Indonesia, Brazil and Africa, it finds structural non-equivalence and uneven representation of smallholders and Indigenous peoples. It proposes a Transparent and Just Environmental Modelling Framework with scenario harmonisation, uncertainty disclosure and participatory appraisal.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本企業のバイオ燃料・農産物調達やScope 3土地利用変化算定は、こうした国際モデルの前提に依存する。モデルの透明性・再現性を問う本稿の視点は、SSBJや有報でのサプライチェーン開示の根拠づけを考える上で示唆を与える。
In the global GX context
Land-use models like GTAP and GLOBIOM underpin biofuel sustainability rules and indirect land-use change factors used in disclosure and trade policy. The paper's call for transparency, uncertainty disclosure and distributive safeguards speaks directly to ISSB/CSRD expectations that modelled estimates be traceable and accountable, and to climate-justice debates in global disclosure.
👥 読者別の含意

📄 Abstract（原文）
Global land-use models increasingly shape assessments of biofuel sustainability, agricultural trade, deforestation and climate mitigation, yet the implications of their methodological choices for the Global South remain insufficiently examined. This qualitative literature review critically compares the Global Trade Analysis Project (GTAP) family, especially GTAP-BIO, with the Global Biosphere Management Model (GLOBIOM). Drawing on peer-reviewed research published from 2020 to 2026, the analysis integrates economic-model architecture, indirect land-use change, ecological accounting, uncertainty, reproducibility and environmental justice. Seven thematic findings emerge: structural non-equivalence; sensitivity of land-use and carbon estimates to assumptions; incompleteness of carbon-centric environmental indicators; spatial and social asymmetries in policy impacts; uneven representation of smallholders and Indigenous peoples; insufficiently standardised transparency; and opportunities for complementary rather than competitive model use. Evidence from Indonesia, Brazil and Africa suggests that model-based trade and climate rules can interact with pre-existing inequalities, although such effects are contingent rather than inherent to either model. The paper proposes a Transparent and Just Environmental Modelling Framework requiring scenario harmonisation, ecological triangulation, uncertainty disclosure, participatory appraisal, distributive safeguards and independent review. It concludes that modelling legitimacy depends on fitness for purpose, traceable evidence and accountable policy interpretation, not solely on numerical precision or model complexity.
