Sustainable Asset Valuation of Waterway Rehabilitation in Cape Town, South Africa
The Nature-Based Infrastructure Global Resource Centre conducted a cost-benefit analysis of nature-based infrastructure (NBI) for waterway rehabilitation in Cape Town, South Africa, specifically within the Diep/Sand River and Zeekoe catchments. The analysis demonstrates that NBI interventions—such as creating retention ponds, extending wetlands, and removing invasive species—provide significant economic returns, reduce long-term maintenance costs compared to grey infrastructure, and increase urban resilience against climate-driven flooding.
