Nearly 97% of the world’s water is in the oceans, but desalination is no magic bullet for water-stressed coastal cities.

Drinkable water resources are becoming increasingly scarce. Are technologies such as desalination capable of averting such a crisis?
New regulations for protecting water resources during oil exploration are inadequate and should be reviewed.
Researchers have long argued that greywater could bolster South Africa’s food security if it’s used to water domestic food gardens.
We need a radical rethink of water resource planning. Strategies should include reusing water and moving water physically to water-scarce areas.
If the world overshoots its climate targets, drought could cause dryland areas to expand by a quarter and encompass half the Earth’s land area, threatening lives and livelihoods.

Academic research can have a direct impact on people's lives. It's crucial to come together to deal with problems like climate change. If we don't, the poor and vulnerable will suffer the most.
A new study maps vegetation’s fire risk across the West and shows where population in the highest-risk areas from California to Texas is booming.
Long before climate change was evident, California began planning a system of canals and reservoirs to carry water from the mountains to drier farms and cities. It’s no longer enough.
As surface water diminishes in the Western US, people are drilling deeper wells – and tapping into older groundwater that can take thousands of years to replenish naturally.
Cities and farmers in the Southwest are resorting to unsustainable strategies to pull in more water. Iran has tried many of these strategies and shows how they can go wrong.
Desalination can help meet growing water needs globally. But toxic wastewater and inefficiency hamper current techniques. A new approach uses custom membranes to clean water more easily.
Pipelines, dams, gadgets: does water management really need to be all about control and power? Adopting less masculine ideas and working with nature may be more prudent.
The US has one of the highest groundwater use rates in the world. When wells run dry, households may opt to conserve water, find new sources or sell and move.
The world’s first futures market for water launched in California in December. Two commodities experts explain how it works, what the potential problems are and why there’s no reason to freak out.
This is not an imaginary future dystopia. It’s a scientific projection of Australia under 3°C of global warming – a future we must both strenuously try to avoid, but also prepare for.
It’s possible to feed the world’s 7.8 billion people with more environmentally friendly farming practices. Here’s how.
From capturing fog to towing icebergs, these technologies could help reduce water shortages.
The projected loss of water storage on land as global temperatures rise is especially alarming in the Southern Hemisphere – and in parts of the US.
To continue to sustain or grow populations — and economies — more is going to have to be done with the same amount of water, or even less.
