イランのハメダン都市域を対象に、都市農業（農地）の炭素貯留・隔離ポテンシャルを実測した研究。土壌・草被・リターの平均炭素隔離量はそれぞれ104.88、4.96、0.27 t/haで、作物別ではジャガイモが最も高くトウモロコシが最も低かった。都市農業を自然基盤ソリューション（NBS）として位置づけ、炭素隔離の生態系サービスを定量化した点に意義がある。
English
This study measured carbon storage and sequestration by urban agriculture (croplands) in Hamedan, Iran, using stratified random soil, grass, and litter sampling. Mean sequestration was 104.88 t/ha (soil), 4.96 t/ha (grass), and 0.27 t/ha (litter), with potato highest and corn lowest among crops. It supports framing urban agriculture as a nature-based solution delivering carbon sequestration ecosystem services.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では都市緑地・農地の炭素貯留はカーボンクレジットや自治体の脱炭素計画と接続しうるが、本論文はイラン事例の実測研究であり、日本のSSBJ開示や政策への直接的示唆は限定的。都市型NBSの定量手法として参考になる。
In the global GX context
Adds empirical evidence on urban nature-based solutions as a carbon sequestration lever, relevant to voluntary carbon markets and city-level climate action, though it sits outside the TCFD/ISSB/CSRD disclosure core.
👥 読者別の含意
🔬研究者:都市農業の炭素隔離を実測した手法と作物別データの参照例として有用。
🏢実務担当者:都市緑地・農地を炭素貯留源として評価する際の定量アプローチの参考になる。
🏛政策担当者:都市計画における農地保全をNBSとして位置づける根拠の一つになりうる。
📄 Abstract（原文）
Abstract Nature-based solutions (NBSs), by maintaining and creating urban green infrastructures (UGIs), can be used to prevent the worst impacts of climate change. Urban agriculture, as an UGI, is widely accepted as an NBS by providing a wide range of ecosystem services (ESs), including food production, wildlife habitat, a sense of place, educational opportunities, nitrogen fixation, flood reduction, improving water quality, local climate regulation, and carbon storage and sequestration. This study aimed to investigate the potential of carbon storage and sequestration ES by urban agriculture (croplands) in the Hamedan urban area. First, a UGI map was prepared, and agricultural lands were extracted. Then, a stratified random sampling was used (120 sampling points). Soil sampling (plot 1 × 1 m), at a depth of 0–30 cm, was conducted, dried (at 105°C/48 h), and analyzed for total carbon content by the dry combustion method (550°C/2 h). Grass and litter samples were harvested (plot 1 × 1 m), oven-dried (at 65°C/48 h), and heated (at 115°C/24 h). The results showed that the average carbon sequestration potential by soil, grass cover, and litter was 104.88, 4.96, and 0.27 t/ha, respectively. Potato (181 t/ha) and corn (58.8 t/ha) cultivation had the highest and lowest soil carbon sequestration values, respectively. Also, flax grass cover had the highest carbon sequestration potential (14.33 t/ha), and tomato plants as a grass cover had the lowest potential (0.3 t/ha). The highest potential of carbon sequestration from the point of view of total soil and grass cover was for potato, flax, garlic, vegetables, abandoned land, peas, fallow land, wheat, tomato, cucumber, rapeseed, and corn. Finally, it can be concluded that urban agriculture can be an NBS for providing carbon sequestration ES.
