South Africa will deal with future water constraints by importing basic foodstuffs from its neighbours.
Urbanisation will require massive amounts of water to sustain the livelihoods of millions expected to move into cities. This may happen at farmers' expense.
In Africa, more than 315,000 children die every year from diarrhoeal diseases caused by unsafe water and poor sanitation.
There have been modest improvements in water and sanitation provision in Africa, but there is still a long way to go. Most citizens rate their governments’ performance in this sphere poorly.
Climate change is forcing some hard decisions when it comes to water use: energy or food production?
The leaders of Ethiopia, Egypt and Sudan signed a Declaration of Principles to move their countries closer to cooperation.
The leaders of Ethiopia, Egypt and Sudan have shown some commitment to sharing the waters of the Nile. But hard negotiations on the Grand Ethiopian Renaissance Dam are only beginning.
Indian children overlook the dry Tawi river, in Jammu, the winter capital of Kashmir, India.
Ambitious plans to divert rivers are all very well, but what is needed is to manage water sources at the local level.
Disruptive innovation is needed if the world is to meet its clean water targets.

Growing population, growing demand for food, climate change: Australia's rural lands are facing a number of pressures. So how can we sustainably use them in the future?
One of Melbourne’s drinking water reservoirs at 30% capacity in 2010. At the time of writing, the dam is 60% full.
Despite its long idle, Melbourne's desalination plant plays a vital role in providing water in a drying climate.

Australians eat a lot of water. Nearly 500 L is required to produce the food each of us eats every day.
So much water has gone into groundwater it has slowed rising seas.

There's enough water under the ground to form a lake 100m deep over the earth.
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.
Australia can balance energy, water and food needs with the environment.

We have all the tools to achieve economic growth and environmental sustainability - we just have to choose to use them.

With El Niño upon us and the prospect of water scarcity ahead, how well positioned are we to make accurate and timely decisions about water resources?
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.
Children from a village in Papua New Guinea’s Western Highlands Province stand in one of countless sweet potato gardens destroyed by frost across the country, August 2015.
Papua New Guinea is now facing a drought and frosts that look set to be worse than 1997, when hundreds of people died. So how can memories of 1997 save lives over the next few months?

Climate change leads to increased likelihood of drought, but strategies for mitigation could make things even worse. How can we resolve the conundrum?

Growth can be predicted and droughts can be planned for. So why did Brazil's largest water utility get caught out?
The Onkaparinga River, part of the catchment that supplies around half of Adelaide’s drinking water.
Imagine a future where the yearly flow into one of the largest water reservoirs of a major Australian city could halve within 70 years. This is a scenario that Adelaide could face if the world continues…
One Nation’s Pauline Hanson says landholders' constitutional water rights have been undermined by government changes – but is that true?

The Australian Constitution says residents have the right to water from the rivers for irrigation and conservation purposes but governments have brought in laws that are restricting this – One Nation’s…
