Plants can find it tough to get all the nitrogen they need, especially from Australian soils. But summer storms can provide an added boost.
While making small volumes of pure water in a lab is possible, it’s not practical. The reaction is expensive, releases lots of energy, and can cause really massive explosions.
Faced with a drought, it's tempting for cities to reduce the amount of space that needs water. But this is not a good idea.
Many countries collect and store rainwater for use during drought or dry seasons. But this technique is rarely used in the Caribbean, where hurricanes can leave people without water for months.
The beauty of rainwater harvesting is that anybody can do it.
Water is increasingly becoming scarce as the climate changes. There are four changes that cities can make to adapt to water scarcity.
Australian cities have turned to some very costly solutions when water is scarce. But as the world's second-highest users of water per person, more efficient use and recycling are key.
States, including Colorado, restrict the use of rain barrels. A water law scholar says a better way to conserve is reduce waste from big – and powerful – water users.
Geosciences can be a valuable tool in the fight to provide Sub-Saharan Africa with safe drinking water.
Built-up urban environments transform the resource of rainwater into wasted runoff. Low Impact Development mimics nature to help get stormwater into the natural water system.
