Nature-Based Infrastructure for Flood Resilience in Ghana

As flooding intensifies across West African cities, new research from Ghana’s Sekondi-Takoradi offers a compelling solution. A recent economic valuation by the International Institute for Sustainable Development (IISD), in partnership with the Sekondi-Takoradi Metropolitan Assembly (STMA), demonstrates how combining engineered infrastructure with restored wetlands and green spaces can offer high-impact, cost-effective protection for vulnerable communities. The study shows that every dollar invested could yield up to USD 13.53 in returns. Download the full report to explore the findings and what they mean for flood resilience in the region.
