エチオピアのジンマ市を対象に、都市緑地の炭素貯留能と熱的快適性への貢献を評価。Landsat 8画像と地理空間技術を用いたUGSCI指標を開発し、緑地状態が良好な地域は18%に過ぎず、地上部炭素貯留量は218万トン、平均炭素密度は208.7 Mg C/haと推定。UGSCIと熱的不快感の間に強い負の相関（R²=0.61）を確認し、緑地改善が都市冷却に有効であることを示した。低コストで再現可能な手法は、他の急速に都市化する都市への適用が期待される。
English
This study assesses urban green spaces in Jimma City, Ethiopia, for carbon storage and thermal comfort using a locally calibrated Urban Green Space Condition Index (UGSCI) from Landsat 8 imagery. Only 18% of the area has good green space conditions, with total aboveground carbon stock estimated at 2.18 million Mg C and mean density of 208.7 Mg C/ha. A strong negative relationship between UGSCI and thermal discomfort (R²=0.61) confirms that improving green space enhances urban cooling. The low-cost, replicable methodology supports sustainable urban planning and climate adaptation in the Global South.

📄 Abstract（原文）
Urban green spaces provide critical ecosystem services, including carbon storage and thermal regulation, yet their condition remains poorly quantified in many rapidly urbanizing African cities. This study assessed the potential of urban green spaces as nature-based solutions for carbon sequestration and human thermal comfort in Jimma City, Ethiopia, using a locally calibrated Urban Green Space Condition Index (UGSCI) derived from Landsat 8 imagery and geospatial techniques. Key findings reveal that only 18% of the study area exhibits good green space conditions, with total aboveground carbon stock estimated at 2.18 million Mg C and a mean carbon density of 208.7 Mg C/ha. Dense vegetation stored substantially more carbon per unit area than built-up areas. A strong negative relationship between UGSCI and thermal discomfort (R 2 = 0.61) confirms that improving green space condition significantly enhances urban cooling. The UGSCI framework offers a replicable, low-cost methodology for monitoring urban environmental quality, readily transferable to other rapidly urbanizing cities in the Global South. By establishing a carbon stock baseline for Jimma City and identifying priority areas for green space investment and highlighting environmental justice implications, this study provides evidence-based guidance for sustainable urban planning and climate adaptation, directly supporting progress toward Sustainable Development Goals 11 (Sustainable Cities) and 13 (Climate Action).
