Cape Town has started down the road of desalination.
Global examples show South Africa that desalination could increase water output.

The experiences of other countries can provide valuable lessons for Cape Town on how to better cope with its water crisis.
Some homes in Cape Town are now harvesting rainwater from their roofs.
Water is increasingly becoming scarce as the climate changes. There are four changes that cities can make to adapt to water scarcity.
The Thomson Dam, Melbourne’s largest water storage, dropped to only 16% of capacity in the last big drought.
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.
Cape Verde’s renewable energy resources account for about 25% of total energy production.
With cutting-edge technologies and innovative business practices, Cape Verde can achieve its goal in a way that is cost-effective and equitable

At present, the Middle East and North African region contains 7% of the world's population but only has access to 1.5% of its renewable freshwater supply through rainfall.

Desalination has been proposed as one of many strategies to deal with the water shortages. But the process is known to be expensive and harmful to the environment.

Scientists have found a way to pull water from the air using only energy from the sun.

Despite its long idle, Melbourne's desalination plant plays a vital role in providing water in a drying climate.

California's drought is dragging on into its fifth year. What can the state learn from Australia's 15-year millennium drought?
Chemistry is all around us.
Our civilisation is built on chemistry, and the science has a bright future, with the launch of a new Decadal Plan that will steer the science into the future.
Despite a decade of drought and declining rainfall in parts of Australia, there’s still plenty of water to go around.

The Millennium Drought ended more than five years ago, but several years of below-average rainfall and El Niño have brought drought back to many parts of Australia. Our latest report on water in Australia shows rainfall is continuing to decline in eastern Australia and increase in the north.
New surveys show Australians don’t mind if the water coming from their tap is recycled.

Would you drink recycled water? New surveys suggest Australians concerned about water shortages are ready for alternative sources.
Water, water everywhere, nor any drop to drink. But not for long.

A desalination breakthrough means industry could provide its own sustainable water supply.
Desalination plants have been controversial, mostly because of their high energy demand and the waste water they produce. But a new desalination technology uses almost no electricity and has the potential…
Drought is a key feature of Australian life.
Much to the chagrin of Australian governments, water managers and farmers, the continent’s signature climate variability and unpredictability has meant that water is generally at the wrong place at the…
