Despite high awareness among professionals, the adoption of permeable pavements as a nature-based solution for urban resilience in South Africa is significantly hindered by underlying causal factors. This sustainability research insight is drawn from a 2025 study published in Urban Science. Using Quantitative research using covariance-based structural equation modelling., researchers explored how this design variable affects real-world outcomes. The key design takeaway: Designers and urban planners should advocate for and implement permeable pavement solutions by actively working to overcome the identified systemic barriers, rather than assuming awareness translates directly to adoption.

Key Findings
- 01Low level of permeable pavement use in South African urban areas.
- 02Encouraging level of awareness regarding permeable pavements among built environment professionals.
- 03Identification of significant causal factors contributing to the poor application of permeable pavements.
Application
Design takeaway
Designers and urban planners should advocate for and implement permeable pavement solutions by actively working to overcome the identified systemic barriers, rather than assuming awareness translates directly to adoption.
How to apply
When proposing sustainable infrastructure, conduct a thorough analysis of local adoption barriers (e.g., cost, policy, technical expertise) and develop strategies to address them.
Project actions
- 01When researching a sustainable design solution, consider not just its technical merits but also the socio-economic and policy factors that influence its adoption.
- 02Use quantitative methods like surveys and statistical modelling to identify and measure the impact of these adoption barriers.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Utilizes advanced statistical modelling (SEM) to identify causal relationships.
- +Addresses a critical gap in literature regarding NbSs in South Africa.
Limitations
The study's reliance on structural equation modelling might oversimplify complex real-world interactions. The specific causal factors identified may be unique to South Africa's context.
Reliability & validity
The use of covariance-based structural equation modelling suggests a rigorous statistical approach, aiming for construct validity and internal consistency. However, external validity might be limited to the specific context studied.
Think critically
To what extent do the identified causal factors for low permeable pavement adoption in South Africa reflect broader challenges in implementing nature-based solutions in other developing urban contexts?
Design Principles
"Effective implementation of sustainable design solutions requires understanding and mitigating systemic adoption barriers, not just raising awareness."
Understanding the barriers to implementing sustainable infrastructure like permeable pavements is crucial for urban planners and designers. Addressing these challenges can lead to more resilient cities, better stormwater management, and improved urban living environments, particularly in regions facing climate change impacts.
What This Means for Your Design
Even though people know about good ideas like permeable pavements for cities, they aren't used much in South Africa because of hidden problems that stop them from being put into practice.
How to use in your project
- 1.This study can inform the context of your design project by highlighting the importance of considering adoption challenges for sustainable solutions.
- 2.You can reference the identified barriers to permeable pavements as a case study for why user or stakeholder engagement and policy analysis are critical in design.

Paragraph starter
This research by Aghimien and Aliu (2025) demonstrates that even with high awareness among professionals, the adoption of sustainable solutions like permeable pavements in urban areas is significantly hindered by underlying causal factors. Their study in South Africa found a low implementation rate despite professional knowledge, underscoring the need to investigate and address systemic barriers beyond mere awareness for successful design project outcomes.
