Aquifers are highly prevalent across Africa – but they’re not always going to be usable.
A saltier Red Sea could threaten its marine life.
Jordan is planning a major desalination plant on the Gulf of Aqaba – but will it damage nearby marine ecosystems?

Fifty years ago, the Salton Sea was a draw for boaters and fishermen; today it’s an ecological time bomb. Two water experts who served on a state review panel describe its proposed rescue plan.
The Carlsbad Desalination Plant in Southern California is the largest such plant in the Western Hemisphere, providing 50 million gallons of desalinated seawater per day.

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

Coastal erosion in West Africa is a cause for global concern. The global community must rally to address climate change which is causing the retreat.
The water cycle is intensifying as the world warms, bringing heavier downpours and longer droughts.
Soil underpins Australia’s economy – yet since Europeans arrived, the natural asset has steadily been degraded. A new national plan aims to change that.

As sea levels rise along the Atlantic coast, saltwater is intruding inland, killing trees and turning coastal forests into marshes. Should scientists try to slow the process, or work with it?

Bangladesh is on the front lines of climate change, but factors including money, gender and religion make some Bangladeshis much more vulnerable than others. Can it find inclusive ways to cope?
The salt in the sea has built up over billions of years – but it wouldn’t have got there without freshwater rivers and streams.
Your salt intake from water can vary depending on where you live.
Of Australia’s capital cities, Perth has the saltiest tap water, while Melbourne, Hobart, Darwin and Canberra have the least salty. And while all are within guidelines, the variation is striking.

Rising seas and groundwater depletion, both driven by climate change, are making soils saltier in many parts of the world. Farmers will need help adapting, especially in developing countries.

As the health of the Murray Darling Basin is in decline, fish ear bones recovered from ancient Aboriginal camp sites can provide vital data about river health in the past.

To address environmental degradation, including climate change, it is essential to take into account human rights and migration. Hybrid international law and regional thinking are both essential.

South west Australia is home to an astonishing number of plants and some of the country’s weirdest wildlife. Now we need to protect it.
Water in a 35 million year old impact crater off the Atlantic coast of North America has been found to be twice as salty…
What does it matter how much rain falls on the ocean? For understanding climate, it matters quite a lot.
Surprising evidence from the oceans suggests they are responding to warming at a faster rate than we previously thought. These changes are expressed by patterns of freshening and enhanced salinity in the…
Scientists say the supply of freshwater in Australia could eventually be at risk.
The cycle of evaporation and rainfall over the past 50 years has intensified at twice the rate predicted by climate change models, according to a report by US and Australian scientists of ocean salt levels…
Our thinly spread efforts to prop up the environment are failing and it is time for tough decisions about what we can realistically preserve.
Australian farmers take pride in their efficient and productive farming systems, competing in the global economy and without many of the large subsidies given to their counterparts in Europe and North…
