本論文は、宮脇方式による高密度植林の炭素貯留・隔離効果をインドで評価。50樹種のバイオマスとCO2吸収量を測定し、Albizzia lebbeckなどが高い吸収能を示した。また、植林による微気候調節（気温低下、湿度上昇）や土壌有機炭素の増加を確認し、将来の植林計画への示唆を提供している。
English
This study evaluates the carbon stock and sequestration potential of high-density plantations using the Miyawaki method in Tamil Nadu, India. Among 50 species, Albizzia lebbeck showed the highest CO2 equivalent. The plantation also improved microclimate (cooling and increased humidity) and soil organic carbon. Findings guide species selection for future afforestation in similar climates.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
宮脇方式は日本発祥の植林手法であり、日本国内でも生物多様性保全や防災、CO2削減を目的に採用されている。本論文はインドでの事例だが、日本における都市緑化や企業の森づくり活動への応用可能性を示唆する。
In the global GX context
The Miyawaki method offers a proven reforestation approach for rapid carbon sequestration and ecosystem restoration. This empirical evidence from India is valuable for global afforestation projects, especially in tropical and subtropical regions, supporting climate mitigation and biodiversity goals under frameworks like the UN Decade on Ecosystem Restoration.

📄 Abstract（原文）
Akira Miyawaki developed a unique reforestation method (the Miyawaki method) in Japan during the 1980s, aimed at restoring native ecosystems, conserving natural habitats, improving disaster resilience and reducing CO2 emissions. This study evaluates the growth performance of tree species planted using the Miyawaki technique at New Thermal Power Station II, Neyveli Lignite Corporation India Limited (NLCIL), Neyveli, where afforestation was completed in 2022. Using a high-density planting strategy, 50 tree species were planted, including timber-species, fruit-bearing trees and ornamental species. Biometric parameters such as plant height and basal diameter were recorded, along with biochemical traits including crude protein, crude fiber and crude fat. Carbon biomass was calculated for each tree and CO₂ sequestration by individual trees was measured to assess their carbon capture potential. The tree species Albizzia lebbeck (14.03 kg tree-1), Diospyros ebenum (13.25 kg tree-1), Terminalia arjuna (12.73 kg tree-1) and Pithecellobium dulce (10.97 kg tree-1) exhibited higher CO₂ equivalents than other species. The Miyawaki plantation alter the local microclimate, with a moderate cooling effect observed during winter, reducing air temperatures to 31.25 °C compared to 32.54 °C in the open area. Relative humidity increased to 59.13 % within the plantation compared to 48.79 % in the open area. The plantation also led to marginal increase in soil organic carbon content. Miyawaki plantations demonstrated positive effects on microclimatic regulation and ecosystem functioning. The findings of this study help identify tree species with superior performance under Miyawaki planting conditions, providing useful guidance for future afforestation programs in areas with comparable climatic and ecological settings.
