According to CSIRO scientist Peter Carberry, these factors, combined with climate change, will challenge our agriculture industry like never before.

"So our second Green Revolution has to be built on increasing our resources' efficiency, getting much greater productivity out of the inputs we use, [while being] conscious of our environment.

"So it is absolutely a challenge as we go into the future, and much more so a challenge than faced in the past."

Mr Carberry says another concern for scientists is the availability of fertilisers going into the future.

"There's that pressure on land as well as issues such as the availability of fertilisers going into the future, such as phosphorus - so we're reaching peak phosphorus [usage] and our access to ready fertilisers is going to decline in the future," he said.
