CNA938 Rewind - Extreme rain and flooding: How climate change Is testing cities

Poh Kok Ing and Hairianto Diman speak to Ang Geck Geck, Singaporean in Bangkok, and Tim Fletcher, Professor of Urban Ecohydrology, University of Melbourne, to examine why cities are vulnerable to intense downpours and how better drainage, green infrastructure and urban planning can reduce flood risk.
