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?

The Bureau of Meteorology recently released for the first time comprehensive national data on recycling and desalination.
Research and technology can improve the yield and sustainability of crops like wheat.
By embracing science and technology, Australia's agricultural industry could be more efficient, productive and sustainable.
Soil and water are crucial resources that need to be carefully studied and preserved.
There will be increasing demands placed on our soil and water in coming years, so we need greater research into how to preserve and maintain these precious resources.
As control over water returns to the state, the Indonesian government should carefully develop policies to manage and monitor water services.
The de-privatisation of water services in Jakarta creates new challenges for the government to ensure universal access to water.
National priorities can help focus our research efforts.

The nine science and research priorities will help focus and coordinate our efforts, and aid government departments in supporting the future of Australian science.
Once there was water….
Some atomic ratio detective work on our solar system neighbors tells us a lot about their watery pasts. That Venus and Mars are mostly dry now could be a cautionary tale for us on the Blue Planet.
How low can it go? The Hoover Dam in May.
As California enters another hot dry summer, policymakers from water and electric utilities are looking at ways to preserve these interdependent resources.
The ice caps on Mars could have been the source of the water flows.
By comparing satellite images of Mars with mud flows on Earth, we managed to find signs of recent running water on the red planet.
Go with the flow: scarce water has allowed Outback species to persist for millennia, where otherwise they might have died out.
The Outback covers 70% of Australia, and its water is precious and scarce. Yet there is no joined-up plan to monitor and manage Outback water, despite the wealth of species and communities that depend on it.
Southern Africa has rivers, like the Zambezi, that run through a number of countries. How best to manage this is the challenge.
Southern African countries do not face water scarcity and do not need to build joint water projects. But they do need talk to each other to avoid misunderstandings.
What if jet fuel could be grown sustainably?
What if you could grow biofuels on land nobody wants, using just seawater and sunlight, and produce food at the same time?
Where do clean water rules begin and end?
The EPA is seeking to clarify the reach of the landmark Clean Water Act to cover tributaries, yet people in agriculture and homeowners worry it will lead to onerous permitting.
Water makes all the difference for agricultural crops.

The majority of water that people use goes to agriculture. In a drier, hungrier future, we'll need to use what water we have with less waste. Technologies being developed now will help.
Universities on the leading edge.
With emergency water rationing in place, how are universities – and other major water consumers – going to conserve?
The Great Artesian Basin is a source of water in many areas of inland Australia.
Recent water leaks related to coal seam gas development in New South Wales raise more concerns about the industry's impact on groundwater.
More land than water: almond trees account for 10% of the state’s water reserves, according to some estimates.
California is blessed with so much agricultural land that no matter how much the state conserves or produces, there will also be an economic incentive to consume more water.
Texas: leading the ‘Shale Revolution.’
The US Geological Survey recently confirmed what many people have already felt: that the rapid spread of fracking has led to more earthquakes.
Artist’s view of a watery asteroid heading to a white dwarf star.
The discovery of a white dwarf star with hydrogen and oxygen in its atmosphere suggests water could be planted on stars and planets by bodies like asteroids.
The ultimate problem: intensive corn production.

A law signed into effect last week seeks to reduce fertilizer runoff that causes toxic algae blooms. But to really address the problem requires taking a hard look at how America farms.
