Cities relied entirely on conserving and recycling water to get through the last big drought. We now have desalination plants, but getting the most out of our water reserves still makes sense.
Sydney and Melbourne are bringing desalination plants back on stream and Adelaide plans to increase its plant's output. Perth depends on desalination. But is it the best way to achieve water security?
South Africa is a water stressed country but crisis point can be avoided.
Undrinkable drinking water is just one example of how blockades and war have permeated an entire ecosystem.
We think of Canada as a water-rich country, but we are not immune to water shortages or disasters. With some advance planning, Canada can avoid a water catastrophe.
