Will we become the world's food bowl? We don't just need water; we need the right soil; the right temperatures; the right access to markets; the right solution to dry-land salinity, etc.
The Ord River scheme allegedly created 260 jobs after decades and $2 billion. Agriculture in the area was abandoned for years after the scheme was completed.
Israel showed how deserts can be transformed Kununurra showed how fertile land becomes with water, and if they treated our sewage via composting instead of flushing it out to sea you could only imagine how fertile the interior of Australia would become, we have enough sunlight and I am sure it would attract huge investment for the future
Okay, what are the sums? How much will the pipeline cost? How much water will it deliver? How many square ks of crops, of what type, will it irrigate? How much will those crops be worth? Who will buy those crops at those prices? After all, if you want investment you must be able to show investors how they will profit from it.
Then please tell us exactly how you are going to deal with rising salinity etc. Also, where is this area of fertile soil and how deep is it?
How much will it cost to get sewerage from whatever city or town it will come from, up and into the fields? How many Australian farmers use human sewerage and will they use it? Will Aussies buy produce that uses human sewerage? Maybe they should, but when a Queensland town was asked whether they would use recycled water they turned the idea down.
What happens downstream of the source of all this nutrients? How will those watercourses cope?
Did you spend much of this summer dealing with a red alert due to blue green algae caused by low water levels and high nutrient loading? I did. It wasn't fun.
