Any policies and interventions around water management can only really be successful if women are included.
Decision making on water infrastructure in peri-urban areas is challenging. But lessons have been learnt from a water project in Mozambique.
Cape Town's draft strategy on water supply is out for comment, but important elements are missing from it.
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?
Neither of the two federal investigations into fish deaths in the Darling River include any Indigenous representation.
While making small volumes of pure water in a lab is possible, it’s not practical. The reaction is expensive, releases lots of energy, and can cause really massive explosions.
Outdated water permit systems are threatening food security on the continent. Here's what can be done.
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.
