Colombo Wetlands Strategy: Cultural Heritage as a Conservation Tool 📈

The International Water Management Institute (IWMI) has launched a new two-year initiative, "Rewriting Colombo’s Wetlands," to safeguard the city’s environmental assets through storytelling and cultural identity. • Overall Impact & Risk: Colombo’s wetlands have seen a 40% reduction in water storage capacity since 2001 due to urban development. Although they cover only 15% of the city, they retain 39% of floodwater during storms, protecting 2.3 million residents. • Project Scope: The project (2026–2028) is funded by the British Academy and partners IWMI with the University of Hull (UK) and the University of Kelaniya. It transitions from traditional science-based conservation to a humanities-led approach. • Strategic Focus: • Community Stewardship: Engaging multi-faith and multi-ethnic communities as active custodians through oral histories, art, and heritage mapping. • Urban Resilience: Leveraging wetlands as vital "green infrastructure" that is more cost-effective than artificial flood-control systems. • Knowledge Integration: Collaborating with the Postgraduate Institute of Archaeology (PGIAR) to incorporate ancient knowledge systems into modern wetland management. • Key Objective: To shift public perception from viewing wetlands as "wastelands" to essential urban assets, creating a transferable model for sustainable development across South Asian "wetland cities."
