Some 85% of Australians live in urban areas: the Australian National Climate Change Adaptation Research Facility (NCCARF) has released a second Policy Guidance brief, focusing on the urban water supply for southwestern Western Australia, which is experiencing a drying trend that is likely to continue in future. Experts note that this could be a valuable learning opportunity for authorities.
Climate independent water sources will play a key role in the urban water supply strategy – in 2005 to 2006, half the water supply was from surface reservoirs, and half was groundwater. In 2013, nearly 50% is from desalination. There are also efforts to reduce demand, and the guidance brief mentions the need to integrate water planning into land-use planning processes, among other things.
