The UK is no stranger to drought – especially southern England.
Accra has become susceptible to floods due to encroachment on wetlands.
We need a radical rethink of water resource planning. Strategies should include reusing water and moving water physically to water-scarce areas.
Millets have been around for thousands of years – and are back in fashion.
When groundwater comes to the surface, sunlight and air convert organic molecules to greenhouse gases. That’s going to be a problem as we will need this water more as the world warms.
Our planet’s invaluable natural store of freshwater is woefully neglected.
Groundwater has the potential to support broad economic, humanitarian and social development in sub-Saharan Africa, as it has in other regions globally.
Water is central to adapting to climate change, but very few of the strategies put in place to respond to water hazards or ensure its availability have been evaluated.
Groundwater is the second-largest store of water on Earth. Governments and industry use groundwater reservoirs to store waste, but it may also have environmental functions that haven’t been revealed.
It’s about developing a community of practice: people who can work alongside scientists, taking science out of the laboratory and into the field.
More than 40 per cent of natural wetlands in the Canadian Prairies have been lost due to drainage, and the impacts associated with this are largely unmitigated.
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.
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.
Some flood dangers can be hard to spot initially – to planners, developers and home-buyers. Sometimes, the danger comes from underground.
Large areas targeted for forest restoration in Africa are covered by savanna and grassland, which provide important ecosystem services that would be lost should they be converted to forests.
Within the growing mountains of electronic waste, precious metals lie waiting to be recovered.
A long-awaited NZ$700 million package to clean up New Zealand’s rivers and lakes has disappointed some of the government’s expert advisers – especially a delay on setting clear pollution limits.
The water that replenishes groundwater, rivers and lakes is under threat from climate change, pollution and aging infrastructure.
Drought-driven humanitarian emergencies can be prevented if groundwater is reliably made available at strategic locations.
