South Africa is a water stressed country but crisis point can be avoided.
Water and energy use are becoming more efficient, which is good news for both the economy and the environment. But Australia has yet to realise the value of national environmental accounting.
Small solutions done properly can play a huge role in dealing with water scarcity.
Residents of a small Victorian town realised that delicious water can be a curse as well as a blessing, when they lost a legal battle to stop a local farmer shipping groundwater to a nearby bottling plant.
World Water Day shines a light on the importance of safe, clean drinking water, but a new report finds Canada's freshwater systems are under stress.
Perth is looking at recycling all its sewage in the city's future water supply. But many Australians' drinking water already contains indirectly recycled treated sewage.
Nature based approaches to solving water problems originated in Europe and don't take into account Africa's huge infrastructure deficit.
There are measures in place to manage Day Zero and beyond. Models show that these will not work.
The situation in Perth in particular has some parallels to that of Cape Town, but Australian cities responded to the last big drought by investing in much bigger water supply and storage capacity.
Developing a map of African countries' water poverty levels offers a transparent analysis for policymakers, governments and organisations that deal with water issues.
Australian cities have turned to some very costly solutions when water is scarce. But as the world's second-highest users of water per person, more efficient use and recycling are key.
Allegations of water theft have thrown the Murray-Darling Basin Plan into crisis. The solution could involve users declaring their annual water use, subject to random audits - like a tax return.
