本研究は、ナイジェリアの都市部における住宅不足と建設由来の温室効果ガス排出増加に対し、循環型建設資材の有効性を系統的レビューとメタ統合により評価した。45件の研究を分析した結果、土系材料やリサイクル骨材、低炭素セメント代替品などにより、構造性能を維持しつつ30～70%の内包炭素削減が可能であることが示された。ただし、技術的・規制的・文化的な制約が普及の障壁となっている。
English
This systematic review and meta-synthesis examines circular construction materials for low-carbon housing in Nigeria. Analyzing 45 peer-reviewed studies, it finds that earth-based materials, recycled aggregates, and low-carbon cement alternatives can reduce embodied carbon by 30–70% while maintaining performance. Successful mainstreaming requires policy support, capacity building, and market system strengthening.

日本のGX文脈において
本論文はナイジェリアを対象としており、日本のGX文脈への直接的な示唆は限定的。ただし、アフリカの都市化と建設需要の高まりを踏まえた低炭素住宅政策の参考として、日本の国際協力や技術輸出の観点で関心を持たれる可能性がある。
In the global GX context
This paper provides a comprehensive evidence base on low-carbon housing strategies for developing countries. Its findings on material substitution and life-cycle integration are relevant to global discussions on embodied carbon reduction in construction, though the Nigeria-specific context limits direct transferability to high-income countries.
👥 読者別の含意
🔬研究者:Methodologically, the systematic review framework and comparative synthesis offer a replicable approach for evaluating circular material strategies in other developing regions.
🏢実務担当者:The identified effective strategies (e.g., earth-based materials, recycled aggregates) and barriers (regulatory gaps, supply chains) can inform pilot projects and material sourcing decisions in Nigeria.
🏛政策担当者:The study underscores the need for coordinated policies—building codes, incentives, and capacity building—to mainstream circular materials, relevant for Nigerian housing policymakers.
📄 Abstract（原文）
Nigeria’s urban housing deficit is increasing alongside rising construction-related greenhouse gas emissions driven by carbon-intensive materials and linear supply chains. This study adopts a systematic review and meta-synthesis approach to examine circular construction materials as pathways for low-carbon housing in Nigeria’s urban communities. A total of 45 peer-reviewed studies published between 2015 and 2025 were identified, screened, and analysed using descriptive statistics, thematic analysis, and comparative synthesis, grounded in circular-economy and life-cycle frameworks. The results indicate that circular material strategies, including earth-based materials, recycled aggregates, industrial byproducts, timber systems, and low-carbon cement alternatives, can achieve embodied carbon reductions of approximately 30–70% while maintaining structural and functional performance. Material substitution, reuse, and local sourcing emerged as the most effective strategies, particularly when integrated across the building life cycle. However, adoption remains constrained by technical capacity gaps, weak regulatory frameworks, fragmented supply chains, limited life-cycle data, and socio-cultural perceptions of alternative materials. The study concludes that circular construction materials provide a practical, scalable, and cost-effective pathway for low-carbon housing in Nigeria. However, their successful mainstreaming requires coordinated policy support, professional capacity development, and strengthened market systems.
