Crops like cotton and rice could be phased out in Australia as calls get increasingly desperate to save the Murray River.
The river is the life-blood of the nation's food bowl, but it is having the life sucked out of it by farms in four states analyists say.
Wetlands connected to the once-mighty river have dried up and trees are dying.
Murray Darling Basin Commission chief Wendy Craik said farmers may have to reconsider planting water intensive produce.
"I think whether those industries continue or not is going to depend very much so on the market and return on investment to farmers and whether water is avaliable or not," Ms Craik said.
