本論文は、エチオピアにおける気候変動による土壌侵食と水文変動に対する自然を活用したソリューション（NBS）の有効性をレビューしている。再植林、アグロフォレストリー、保全農業などの介入により、土壌損失が40～70%削減され、ピーク流出低減や乾季の水利用可能性向上が確認された。ただし、スケーラビリティは土地所有権の不安定性や制度的制約に阻まれている。
English
This review assesses the efficacy of Nature-Based Solutions (NBS) in mitigating climate-driven soil erosion and hydrological change in Ethiopia. Interventions such as reforestation, agroforestry, and conservation agriculture reduce soil loss by 40-70%, lower peak runoff, and improve dry-season water availability. Scalability is constrained by land tenure insecurity and limited institutional capacity.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本でも気候変動に伴う豪雨災害や土壌侵食が課題となる中、NBSの体系的な効果検証は参考になる。ただし、本レビューはエチオピアに特化しており、日本のGX文脈（SSBJや開示制度）との直接的な関連は薄い。
In the global GX context
This paper provides a systematic synthesis of NBS effectiveness in a climate-vulnerable context, relevant to global adaptation frameworks such as the IPCC and the UNFCCC. It underscores the need for integrated, landscape-scale approaches, which aligns with the growing emphasis on nature-based solutions in climate policy worldwide.

📄 Abstract（原文）
Abstract Ethiopia faces severe climate-driven hydrological variability and accelerated soil erosion. While Nature-Based Solutions (NBS) are increasingly promoted to mitigate these interconnected threats, empirical evidence regarding their context-specific efficacy remains fragmented. This critical knowledge gap currently hinders scalable climate adaptation and effective watershed investment. To address this gap, this review synthesizes empirical and model-based studies to assess NBS efficacy in mitigating soil erosion and hydrological change across Ethiopia. The review examines key interventions, including reforestation, wetland conservation, agroforestry, conservation agriculture, and physical soil and water conservation measures. Results indicate that well-designed NBS can reduce soil loss by 40–70%. Furthermore, they successfully lower peak runoff, enhance infiltration, and improve dry-season water availability. These benefits are maximized when physical measures are combined with vegetation-based interventions. Intervention effectiveness relies heavily on agro-ecological conditions, watershed position, proper maintenance, and community participation. Integrated, landscape-scale approaches consistently outperform isolated, single-measure interventions. They deliver synergistic benefits for erosion control, water regulation, and rural livelihoods. Despite these successes, scalability is constrained by land tenure insecurity, limited institutional capacity, and lack of long-term monitoring. Future research must prioritize spatial targeting, performance under compound climate extremes, and water-yield trade-offs. Overall, contextually tailored and socially inclusive NBS represent a robust pathway for climate-resilient land and water management in Ethiopia.
