To address the issue, Dr Faith Ka Shun Chan has been committed to the research of Sponge Cities. The concept of “Sponge City” is that a city structured and designed to absorb and capture rainwater and utilise it to reduce floods. It is a form of a sustainable drainage system in urban scale.
Dr Faith Chan’s research explicates the “Sponge City” concept and implications to land-use planning and water management measures. His research has helped identify the best practices to address urban flood issues in Ningbo and other Chinese cities.
