アフリカ42カ国・134都市・112研究を対象とした系統的レビュー。都市緑地が証拠の49%を占め最も多機能だが、都市農業は過小評価されている。適応成果は72%、緩和成果は27%の研究で報告され、緑地近傍で最大12.2°Cの気温低減が確認された。長期資金不足と生計・移転への影響が課題として挙げられている。
English
A systematic review of 112 studies across 134 African urban areas in 42 countries. Urban green spaces dominate (49%) and are most multi-functional, while urban agriculture is under-recognised. Adaptation and mitigation outcomes were reported by 72% and 27% of studies respectively, with temperature reductions up to 12.2°C near green-blue spaces. Long-term funding gaps and displacement risks remain key concerns.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本企業にとっては、アフリカ都市での適応型インフラ・自然資本投資の機会と、TNFDや生物多様性クレジットに関連するリスク評価の参考になる。適応策の資金メカニズムやコミュニティ参加の知見は、グローバルなサステナビリティ戦略に示唆を与える。
In the global GX context
This review adds African urban evidence to the global NbS and adaptation literature, complementing TCFD/ISSB-aligned physical risk disclosure and TNFD nature-related reporting. It highlights financing gaps and equity concerns relevant to transition finance and just transition debates, though it does not directly address corporate disclosure frameworks.

📄 Abstract（原文）
Abstract Nature-based solutions (NbS), including ecosystem-based adaptation (EbA), are increasingly proposed for climate action in African cities, but the evidence base is fragmented and lacks systematic synthesis of what is being implemented, where, and how effectively. We analysed 112 studies retained from a systematic review, covering 134 urban areas across 42 countries and including 45 informal settlements. Five NbS typology classes are inductively derived including: Green spaces; Rivers, catchments and drainage systems; Coastal systems; Green buildings; and Urban agriculture and multi-use gardens. Urban green spaces dominate the evidence (49% of studies) and are the most multi-functional class. Urban agriculture and multi-use gardens are under-recognised in headline framings, named as primary in only 5% of studies but appearing in 34% of the wider intervention mix. Evidence is increasing but concentrates geographically on larger cities. Successful climate change adaptation and mitigation outcomes are reported by 72% and 27% of studies, respectively. Heat mitigation is the most frequently quantified adaptation outcome, with temperature reductions up to 12.2°C reported in proximity to urban green and blue spaces across the continent. Qualitative evidence links urban NbS to effective coastal protection, flood risk reduction, and increased water security. Multi-stakeholder governance anchored by local actors, and meaningful community participation are consistent enablers of effective implementation. However, insufficient long-term funding and livelihood disruptions and displacement raise concerns about long-term impacts. Priority research gaps include longitudinal effectiveness monitoring, financing mechanisms for informal contexts, systematic assessment of mechanisms behind inequitable outcomes, and evidence from under-represented regions and smaller cities.
