7 thoughts on “Clearing “A Million Acres a Year” in SW Western Australia”

  1. Reads like Greenie propaganda aimed at schoolchildren.

    The reality is that Western Australia feeds many times more people than the population of the state. The implication of parts I read is that is a bad thing. Easy to say if you aren’t one of those doing the eating.

    Government policies were misguided, but they frequently are. Contrary to what they claim, salinity was poorly understood. Farmers wouldn’t deliberately ruin their land for agriculture.

    Finally, most of the eastern Wheatbelt was settled for agriculture after WWI. I wasn’t aware that much land was left for settlement after WWII and I couldn’t find any figures. I know farms in the far east of the Wheatbelt up against the vermin fence and in the northeast around Wongan Hills have been there since the 1920s.

    In fact after WWI there was some settlement beyond the vermin fence, but these farms were abandoned in the 1930s during a drought and under government pressure.

  2. As the old saying goes “one swallow doesn’t make a summer”.

    The point is, the estimated crop would be 2.7 million tonnes greater and provide a further $2.0 billion in increased export dollars and an additional $500m pa benefit to the towns and businesses who would supply the seed, fertilizer, tractors etc
    to the towns.

    As greenies are opposed to farming and want the land to its former natural state, what are us mere mortals supposed to eat
    and earn an income?

  3. I used to work as a stock agent in the southwest all through the seventies. Many times I saw the devastation of drought on farmer’s incomes, at times going to clearing sales weekly, farmers forced to leave even the better rainfall districts. Then there were the average years and occasionally, a very good year, like the last few years.
    This global warming is just amazingly good. Despite a much cooler winter and spring this year.
    Temperature has only small impacts, but rainfall has a huge impact.

  4. The National Library has 1940’s aerial photos of many regions over the wide brown land. It would be an interesting research project mapping areas of bush circa 1950 that are cleared today.
    Here are some links for mostly four-mile sheet names. I do not know if the scans in DOLA were photographed circa 2000 or if they are 1940’s images scanned in 2000. It does look as though in the 1940’s RAAF aircraft sure were sent forth with cameras to photograph. Maybe good navigation training too.

    I have been into the National Library to look at NSW frames from the 1940’s – they wheel out bundles of photos in boxes and let you use a laptop & scanner.

  5. ‘Temperature has only small impacts, but rainfall has a huge impact.’

    On salinity as well. Although I can’t recall seeing any reference to it.

    Salinity drawn to the surface is a widespread problem in WA. Even in Perth. I have limestone retaining walls in my yard, and after a week without rain, you can see the salt glistening on the surface.

    In Perth we get enough rain to flush the salt out of the soil surface layer . In the salinity affected areas, there isn’t enough runoff from rain to flush the salt.

  6. This document is complete claptrap, and is part of the salinity scare of the early 2000’s which was the precursor to the climate change scam.

    As opposed to the theory that removing native vegetation allows the water table to rise bringing with it the salt, the reality is that roads and railway lines inhibit surficial flows at shallow soil depths who are returning to the ocean the salt that has been brought onto the land-mass via rain.

    All native vegetation does is hold the salt at the base of their roots until the average 1 in every 40-50 year rainfall event flushes it out. If salt is prevented from returning to the ocean then after a few centuries all land masses would be covered in a few cm of salt, which wouldn’t be that useful.

    In addition all growing big stands of trees does is build up such a big bank of salt that when the big flush comes along it passing to the ocean becomes extremely toxic and is likely to contaminate and damage everything in its path. This theory was developed by public servants and should be viewed with the same amount of skepticism that you would treat someone who is trying to sell you a harbour bridge.
