Abstract

Purpose The study aims to examine the potential benefits of integrating nature-based solutions (NbS) in the housing sector. Design/methodology/approach The approach adopted was a systematic literature review aided by the Preferred Reporting Items for Systematic Reviews criteria and the VOSviewer software. Abductive reasoning was used to analyze the collected data, which was then subjected to content analysis through an iterative read-and-review procedure. Findings The study identified green walls, indoor greenery, porous pavement and landscaping, rainwater harvesting and water purification and green roofs as elements of buildings where NbS should be incorporated. Although nature-based research on integrated greenery facades and roof applications was noted, rainwater harvesting and water purification-oriented research remained dominant. These findings demonstrate the advantages of implementing NbS in the housing sector, including energy efficiency, environmental development, flood prevention and sustainable water management. Integrating NbS into housing designs can considerably contribute to the creation of more resilient, eco-friendly and comfortable living environments. However, the adoption of NbS faces hurdles, including a lack of awareness, limited policy support and economic constraints. Practical implications This study recommends that NbS be mainstreamed into housing development and knowledge exchange opportunities between sub-Saharan Africa and Europe, as well as other regions, to promote the adoption of NbS through research and collaborations. Also, it contributes to the discourse of sustainable affordable housing in the Global South while addressing United Nations Sustainable Development Goals 11, 12, 13 and 15. This study offers valuable guidance to stakeholders, thereby fostering the development of more sustainable and resilient housing practices and policies. Originality/value The study used VOSviewer software visualization to identify structural patterns and track prominent research frontiers, allowing for a more thorough yet concise mapping and capture of a scientific knowledge domain.
系统审查基于自然的解决方案(NbS)在非洲住房交付中的作用
目的本研究旨在探讨将基于自然的解决方案(NbS)纳入住房领域的潜在益处。采用的方法是系统性文献综述,以系统性综述首选报告项目标准和 VOSviewer 软件为辅助。研究发现,绿墙、室内绿化、多孔铺装和景观美化、雨水收集和水净化以及绿色屋顶都是应纳入 NbS 的建筑元素。尽管有关综合绿化外墙和屋顶应用的研究以自然为基础,但以雨水收集和水净化为导向的研究仍占主导地位。这些研究结果表明了在住房领域实施氮化建筑系统的优势,包括能源效率、环境发展、防洪和可持续水资源管理。在住房设计中融入氮化态系统可大大有助于创造更具弹性、生态友好和舒适的居住环境。本研究建议将核安全纳入住房开发的主流,并为撒哈拉以南非洲和欧洲以及其他地区提供知识交流的机会,通过研究和合作促进核安全的采用。此外,本研究还有助于在全球南部地区讨论可持续经济适用房问题,同时实现联合国可持续发展目标 11、12、13 和 15。本研究为利益相关者提供了宝贵的指导,从而促进了更具可持续性和复原力的住房实践和政策的发展。原创性/价值本研究使用 VOSviewer 可视化软件来识别结构模式并跟踪突出的研究前沿,从而能够更全面、简洁地绘制和捕捉科学知识领域。
