2007〜2025年のバイオ炭×エネルギー作物研究409件を文献計量と批判的レビューで分析。研究はバイオ炭の製造・物性評価から圃場スケールの農学的性能、熱分解炭素の残留性、LCA、GHG削減、機能性バイオ炭へと移行。土壌炭素蓄積と永続的隔離の可能性を示す一方、熱帯条件での長期検証不足や指標の非標準化を課題として指摘する。
English
A bibliometric and critical review of 409 records (2007–2025) on biochar in energy-crop systems. Research has shifted from production and physicochemical characterization toward field-scale agronomic performance, pyrogenic carbon persistence, LCA, GHG mitigation, and engineered biochars. Evidence supports biochar as a soil-carbon and carbon-management strategy, but long-term tropical validation and standardized indicators remain gaps.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では農林業由来バイオマスの炭化による炭素隔離がJ-クレジットやGX推進の炭素除去源として注目される。本レビューは圃場検証や指標標準化の必要性を示し、国内の炭素貯留クレジット設計や農業系脱炭素の議論に示唆を与える。
In the global GX context
Biochar soil carbon sequestration is increasingly relevant to voluntary carbon markets and durable carbon removal accounting under emerging frameworks. The review's call for harmonized indicators linking productivity, soil carbon, GHG, and permanence speaks directly to MRV and carbon-credit integrity debates in global disclosure.

📄 Abstract（原文）
Abstract This bibliometric and critical review examines the evolution of scientific research on biochar application in energy-crop systems, emphasizing biomass productivity, soil quality, and soil carbon sequestration from 2007 to 2025. The bibliometric assessment comprised 409 records retrieved from the Web of Science Core Collection and integrated publication trends, thematic evolution, scientific collaboration networks, and agronomic and environmental evidence. Scientific production increased markedly during the period, despite interannual variability, accompanied by a shift from biochar production and physicochemical characterization toward field-scale agronomic performance, soil–biochar interactions, pyrogenic carbon persistence, life-cycle assessment, greenhouse gas mitigation, and engineered biochars. Physicochemical characterization nevertheless remained essential for interpreting biochar functionality. Field evidence indicates that crop responses depend on feedstock origin, pyrolysis conditions, biochar properties, application rate, soil characteristics, crop species, and experimental duration. Long-term studies and assessments of pyrogenic carbon stability support the potential of biochar to increase soil carbon stocks and contribute to durable carbon sequestration, although the magnitude and permanence of these effects vary across pedoclimatic conditions and management systems. Major research gaps include limited standardization of biochar characterization, insufficient long-term field validation under tropical conditions, incomplete evaluation of the environmental safety of modified biochars, and the absence of harmonized indicators integrating biomass productivity, soil carbon dynamics, greenhouse gas emissions, and carbon permanence. Overall, current evidence supports biochar as a soil amendment and carbon-management strategy for low-carbon bioenergy systems when material properties and application practices are aligned with site-specific agronomic constraints and validated under representative field conditions.
