Hong Kong cannot afford the false luxury of wasting water
Su Liu calls for holistic management of Hong Kong's water resources, which means officials must do more to capture and recycle wastage
In his policy address last week, Chief Executive Leung Chun-ying made it clear that "Hong Kong needs sustained economic growth to address issues such as poverty, housing, an ageing society, environmental protection and the upward mobility of our young people". Sound familiar? Yes, it is an elaboration of Deng Xiaoping's famous saying, "Development is an absolute principle".
Did Leung mean that "sustained economic growth" is the magic pill to solve Hong Kong's problems? Or was he trying to say that we should seek economic development in a sustainable manner?
Sustained economic growth means achieving growth at any cost; while sustainable development means that at times there may appear to be no growth, but in the long term, growth is sustainable.
Even if economic growth were the sole objective, the policy address missed some fundamental factors enabling such growth. Water is one of them. By nature, Hong Kong's water is in short supply. So what did Leung say about a sustainable water policy for sustained economic growth? Almost nothing.
The "total water management" strategy launched in 2008 governs Hong Kong's water resources management. Ideally, such a strategy would ensure Hong Kong can manage its water in a closed loop.
