本研究はニジェールの4都市における公共緑地の木本植物多様性と炭素貯蔵・隔離能を評価した。合計15,719個体（47種）を記録し、総炭素ストックは747.81 tC/ha、CO₂換算で2,744.46 tCO₂/haと推定された。都市緑地が気候変動緩和に果たす役割を定量的に示している。
English
This study assessed woody plant diversity and carbon storage in public green spaces across four cities in Niger. It inventoried 15,719 individuals (47 species) and estimated total carbon stock at 747.81 tC/ha, equivalent to 2,744.46 tCO₂/ha sequestered. The findings highlight the climate mitigation potential of urban green spaces in arid regions.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本の都市緑化政策やカーボン・オフセット制度にとって、乾燥地における緑地の炭素貯蔵能を示す本知見は参考となる。ただし、SSBJやTCFDとの直接的な関連は薄い。
In the global GX context
This paper provides empirical evidence on nature-based carbon sequestration from a data-scarce region, supporting urban climate planning and IPCC greenhouse gas inventory guidelines. It strengthens the case for integrating urban green spaces into global carbon accounting frameworks.
👥 読者別の含意
🔬研究者:Provides baseline data on urban tree carbon storage in West Africa, useful for comparative studies and meta-analyses.
🏢実務担当者:Urban planners and local governments can adopt the field methods to assess carbon benefits of their own green spaces.
🏛政策担当者:Supports inclusion of urban green spaces in national climate mitigation strategies and NDCs, especially for dryland regions.
📄 Abstract（原文）
Urban green spaces contribute to biodiversity conservation and climate regulation, but their woody plant composition and carbon sequestration potential remain insufficiently documented in the Republic of Niger. This study assessed woody plant diversity, biomass, carbon storage and carbon dioxide sequestration within public green spaces in Niamey, Maradi, Tahoua and Zinder cities. Woody plants with a diameter at breast height of at least 3 cm were inventoried using a stratified random sampling approach across selected categories of public green space. Measurements included species identity, total height, diameter at breast height and green space area. In total, 15,719 woody individuals were recorded, representing 47 species, 41 genera and 24 botanical families. Fabaceae was the most represented family, accounting for 23.40% of recorded species. The flora was dominated by dicotyledons, which accounted for 93.62% of the floristic assemblage. Azadirachta indica was the most abundant species, representing 81.86% of all inventoried woody individuals. Total biomass varied across green space types, ranging from 3.83 t/ha in parks to 299.55 t/ha in memorial green spaces. Overall carbon stock was estimated at 747.81 tC/ha, corresponding to 2,744.46 tCO₂/ha of sequestered carbon dioxide. The findings show that public green spaces in Nigerien cities support woody plant diversity and provide measurable carbon storage benefits, highlighting their relevance to urban climate mitigation and sustainable planning.
