Time-lapse animations that once took days to create are now easy to build with publicly available satellite images and free online tools.
Redwood forests like this one in California can store large amounts of carbon, but not if they’re being cut down.

Millions of dollars have gone into California’s forest carbon offset program – with little new carbon storage to show for it, a new study suggests.
Satellite imagery monitors environmental changes to inform agricultural decisions. Agricultural patterns are distinctly visible in this near-vertical false colour infrared photography of farmland south of Khartoum, Sudan.

Technologies being developed for growing food in space have contributed to advances in agriculture and crops on Earth.
NASA’s Worldview software gives you a satellite view of Earth right now, and can help track the spread of fires.

China has embraced the concept of Digital Earth – the use of data from satellites to create a visual map of what’s happening at every point on the planet – and is now a key player in making it happen.
The electromagnetic spectrum we can access with current technologies is completely occupied. This means experts have to think of creative ways to meet our rocketing demands for data.

Free space optical communication will allow the same connectivity in space we already have on Earth. And this will provide benefits across a number of sectors.
Monitoring the whereabouts of floodwaters is vital for protecting infrastructure.

The flood zone around Townsville extends for hundreds of kilometres, making monitoring difficult even from the air. But scientists are testing a new satellite method that can peer through the clouds.
Satellite data includes digital imagery of factors that affect farming.

Big data can be used to properly advise smallholder farmers in Africa and help guide pest monitoring efforts.
Where there’s smoke, there will be lava?

How do scientists predict volcanic eruptions? To do so with accuracy, they need to know the individual volcano and its history very well.
Under the proposal, irrigators would have to submit a statement that tallies with aerial images of their water use.

Allegations of water theft have thrown the Murray-Darling Basin Plan into crisis. The solution could involve users declaring their annual water use, subject to random audits - like a tax return.
