Flood protection won't work in climate-changed environment

A climate change researcher says local and central government must stop allowing houses to be built in at-risk areas and we should no longer rely on flood protection infrastructure such as stopbanks to protect against climate change-induced major weather events.  Last weekend's devastating flooding has rendered 15 percent of Westport homes uninhabitable. Kathryn talks to Judy Lawrence from the Climate Change Research Institute about how we can better protect our infrastructure.
