Mike Young, executive director of the Environment Institute at the University of Adelaide, talks to Romesh Vaitilingam about how Australia has responded to the big shock to its water supply – through new regulations, through technological solutions, through public education and through the introduction of market mechanisms. The interview was recorded at the Global Economic Symposium in Schleswig-Holstein in September 2009.
