YOu do realise, the salt in the Murray and MIA didnt come from the irrigation per se right.

Sprintcyclist wrote on Jan 16^th, 2018 at 1:51pm:




Then dumping a shiteload of water on it, thereby bringing the water table up and the salt was in that water

Wow. That's deep.

So having achieved the dream of irrigating Central Australia, what will you do with it?

It will cost millions. What will you do to recoup the money spent?  Grow blue gums?

Crikey, where do I start?

There are plenty of inland areas that have fantastic soil and plenty of water.

But its not economic at present to grow anything out there.

Even Kununurra with massive water supplies and good soils is struggling to find economic crops.

The shonky Sandalwood Ponzi schemes are one of the main things keeping Kununurra alive.

The Chinese are going to throw some money into the Ord, however it will probably not be viable for decades.

...........The Ord River irrigation scheme has been plagued by delays, cost blowouts and planning problems, an independent report into the West Australian Government's effort to open up additional farmland in the East Kimberley has found.

Auditor-general Colin Murphy's report into the Ord-East Kimberley Development, an expansion of the original 1970s program to open up farmland in the region, described it as a two-year, $415 million project which took seven years and ended up costing the state and federal governments $529 million.

Mr Murphy detailed a $24 million accommodation facility which has sat vacant for three years, a 52 per cent blowout in costs to the state and lower-than-expected economic and social benefits.

The report also criticised planning problems, stating there were no detailed costings to support the state's decision to fund the project, an unrealistic estimate of the work required, and insufficient monitoring of socio-economic outcomes........

If the Chinese fly in their own slave labour, then get access to the Chinese market, they may be marginally viable.

LEave it. Work on increasing the efficiency of our current farming land.

.............Impacts by state[edit]
New South Wales[edit]
Currently 5% of New South Wales is affected by dry land salinity, and around 50% is under threat.[9] 15% of current irrigated land is impacted, and up to 70% is currently under threat.[9] The main regions currently affected, and at high risk, are The Murrumbidgee River catchment near Griffith, and Jemalong River Catchment near Forbes, as well as the Murray River irrigation area near Deniliquin.[9]

Victoria[edit]
The current levels of salinity in Victoria are relatively small, with the main impact expected to occur in high risk areas in the coming years. These high risk areas include the Campaspe, Loddon, Corangamite, Glenelg-Hopkins, Goulburn-Broken catchments, and Wimmera and Mallee regions.[10] The current cost to Victoria is estimated at $50million per year. This is expected to rise significantly with the impacts on agricultural land, wetlands and infrastructure in high risk areas to increase, mainly in part to an anticipated 10 fold increase in salt levels by 2050.[9]

Western Australia[edit]
Western Australia contains the majority of land affected by salinity in Australia, with around 70%. Over 2 million hectares are currently affected, and around 4 million hectares of land are currently listed as high risk, and 50% of divertible water is already considered overly saline.[9] Around 450 plant species are endemic to areas that are at high risk of salinisation[11] 75% of water bird species in decline, a 75% reduction in sealed road life, and $400million in lost profits.[9]

South Australia[edit]
Salinity in South Australia is a problem in all principal agricultural areas, with 370000 hectares of land and wetlands impacted. At current rates, this is expected to increase by 60% by 2050.[12] It is expected to cost the state around $47million per year in lost agricultural profit, and is expected to taint more than 20% of ground water to levels above those safe for human consumption.[9]

Tasmania[edit]
Tasmania is relatively unaffected by salinity, with around 1% of agricultural land, and 8% of farm land adversely affected by salt, resulting in a current cost to the state of around $5million per year, rising to around $13million by 2050. The majority of this salinity is irrigation based.[9]

Queensland[edit]
Queensland is the least affected state of Australia, due to its unique seasonal rainfall. Around 15000 hectares are currently affected, with 3.1million hectares considered highrisk.[9] At current rates however, salinity is predicted to have moderate scale impacts on land and infrastructure by 2050, with 12,000 km of roads, 1500 km of rail lines, and around 2.8million hectares of agricultural land, remnant vegetation, and wetlands and streams negatively affected[13]............

............. The final report for the NAPSWQ states that ‘With few exceptions the massive efforts involved in delivering NAPSWQ and NHT programs have at best halted the degradation of these resources. This has reinforced the view of the State of Environment (SoE) Report that concluded that the condition of these resources continues to decline despite the best efforts of the community and government'.[18].............

So will irrigating Central Australia bring any salt there to the surface?

There are two main ways to  make saline soils.

If there is an underlying saline water table and you raise that water table (most of Australia's problem)

OR

If your irrigation water is ever so saline and you can not flush and drain the soil the salt will build up.

In Carnarvon WA they have to monitor the salt levels in irrigation water very closely and stop using it if the salinity builds up. There is bugger all rain and also poor drainage means you can bugger up the soil with irrigation.

and this thought .........

Aust is benefited by lowering the local water table level and flushing it out with fresh water

A long way for anything

Easy peasy.

Only 1 Party had policies contained in a platform called WATERING AUSTRALIA.
The Greens...  nope
The Libs... Nope
The ALP... nope
The Nationals... nope...

Too far from 'the market and infrastructure' ?

Yes thats part of the problem.

Try getting people to work out there.

Try keeping produce cool

Try getting transport on unsealed roads.

Try controlling some of the pests

Irrigating a machinery planted and harvested crop that does not need cool storage is half a chance.

There is already an irrigation scheme in north western Australia. The Ord River scheme has been running since Lake Argyle was created in 1972 with only limited success.
