The resilience of Australia's major cities to flooding and drought has been advanced through a range of economic and physical interventions. Water-sensitive urban design irrigates vegetation with harvested storm water that improves water security, flood risk, carbon sequestration, biodiversity and air and water quality and delivers cooling that can save human lives in heatwaves . Stormwater harvesting is supported by some councils in New Zealand and can deliver recycled water for households , improving climate resilience and reducing water demand . Addressing infrastructure vulnerability is essential given the long lifetime of assets, criticality of services and high costs of maintenance .
