The Darling, a major river in New South Wales, Australia (where Sydney, Canberra, and Melbourne are) has all but dried up. It’s not addressed in this article, but I recall that Australia’s political system has managed to anticipate and adapt to climate change reasonably well when it comes to drinking water for its major coastal cities. But one thing this article notes is that the country has gone from a net exporter to a net importer of wheat. It is also indigenous populations in the more rural areas who tend to bear the brunt.
