日本語
本レビューは、バイオ炭による劣化土地（鉱山跡地、泥炭地、塩類土壌、乾燥地、侵食農地）の修復メカニズムと応用を整理した。バイオ炭は土壌団粒形成、保水・保肥性、陽イオン交換容量、pH、微生物機能を改善し、毒性物質の生物利用能を低減する。農業・森林残渣を原料とすることで土壌炭素貯留、GHG削減、水質改善、循環型バイオエコノミーに寄与するが、原料・熱分解条件・経済性・品質標準化・政策支援が課題として残る。
English
This review synthesizes biochar's role in rehabilitating degraded lands—mine sites, peatlands, saline/sodic soils, drylands, and eroded farmland. Biochar improves soil aggregation, water/nutrient retention, CEC, pH, and microbial function while reducing toxic bioavailability. Using agricultural and forest residues supports soil carbon storage, GHG reduction, water quality, and circular bioeconomy, though feedstock, pyrolysis conditions, economics, standardization, and policy support remain constraints.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では農地保全・地方創生・J-クレジット（バイオ炭施用）と接点があるが、本論文はインドネシア等の劣化地が中心で、日本のSSBJ開示や有報対応への直接示唆は限定的。炭素貯留クレジットの科学的根拠として参考価値はある。
In the global GX context
Biochar as a nature-based carbon removal pathway connects to voluntary carbon markets and soil-carbon methodologies under emerging MRV frameworks, though it sits outside core TCFD/ISSB disclosure infrastructure. It adds evidence for land-based removals relevant to net-zero transition planning and CSRD-linked biodiversity/land-use reporting.

🏢実務担当者:バイオ炭施用や残渣活用を炭素貯留・循環調達の選択肢として検討する際の根拠になり得る。
🏛政策担当者:バイオ炭の品質標準化と普及支援策、土壌炭素クレジット設計の論点整理に資する。
📄 Abstract（原文）
Land degradation poses a growing global environmental concern that threatens soil productivity, ecosystem services, biodiversity, and climate resilience. Biochar is generated by thermochemically processing biomass in an oxygen-restricted environment and is a viable nature-based solution for soil degradation and sustainable land management. This review synthesizes recent knowledge on the qualities of biomass-derived biochar, mechanisms for improving soil properties, and its application in different degraded lands, including mine-degraded lands, peatlands, saline and sodic soils, drylands, and eroded agricultural lands. Biochar enhances soil quality and contributes to restoring ecosystems through improved soil aggregation, water and nutrient storage, enhanced cation exchange capacity, soil pH and microbial functioning, and by reducing soil acidity and bioavailability of toxic substances. Furthermore, the use of agricultural and forest residues as feedstock for biochar production helps maintain carbon in the soil over extended periods, reduces greenhouse gases, improves water quality, and supports a circular bioeconomy. However, biochar performance is influenced by several factors, including feedstock characteristics and pyrolysis conditions, soil properties, and environmental considerations. Economic feasibility, quality standardization, and governmental support remain major concerns. The review emphasizes the various functions of biochar in the reclamation of degraded lands and indicates the future research needs to foster sustainable land management and climate change mitigation.
