Attaining urban water sustainability in Hong Kong: Three suggestions.

Over several decades, Hong Kong has implemented a number of technological innovations for securing its water supply. But as population growth and the effects of climate change put pressure on existing water sources, new innovations combined with social adaptations will be required. This commentary offers three suggestions for moving toward urban water sustainability in Hong Kong. The suggestions are: diversify sources of water while minimising dependence on desalination, foster public engagement with water and implement water‐sensitive urban design. These suggestions are not intended to be a panacea but to augment existing measures that when combined can move toward the attainment of urban water sustainability. [ABSTRACT FROM AUTHOR]
