Australia is aridifying as its climate changes. Scientists advise this is due to the southward shift of global pressure zones as well as the re-radiation of extra heat from bare areas that create high pressure heat domes that block the inflow of moist low pressure air.

The consequence is lower rainfalls, reinforcing that we have to conserve and more efficiently use every drop. Can we harvest more of the water that flows continually over most landscapes from the 'rivers in the air?'

 

The discussion in the film explores the natural processes and evidence in our landscapes and if we can potentially access these unrecognised sources of water to help rehydrate the land.
