 Too many unknowns for effective Basin Plan 

Too many unknowns for effective Basin Plan

07 Dec, 2011 02:30 AM
Professor of Environmental Science with the Australian Wetlands and Rivers Centre, Richard Kingsford, says that there is still too much we don't know about the Murray-Darling Basin.

Making plans without adequate knowledge is setting us up for future water debates "full of angst and uncertainty", he argues.

Prof. Kingsford says we don't know:

  • the real impacts of water resource development;

  • the effect of restoring water removed from the environment by irrigation;

  • how different ecosystems and organisms respond to different volumes of water;

  • whether trees are a good surrogate for the environmental health of other organisms;

  • what effect climate change will have on water flows. There is no modelling of river health under climate change.

  • the effect of doubling groundwater extractions of river flows, as proposed by the plan. This may nullify the impacts of putting more water into the rivers;

    What we do know is that the fascist greens are using any excuse to bash communities that depend on our rivers for a living

    It is not so much a question of what we don't know. Rather, the issue is what the MDB Mafia and the greenscum don't want to know and refuse to find out.

    Whereare the baseline conditions of the basin before clearing increased catchment flows by 50%, as estimated by Zang et al of the now defunct CRC for Catchment Hydrology?

    Where is the proper mapping of red gum forest that expanded due to this increased yield and other areas that declined from too much saturation? Until we can reconcile those changes with the pros and cons of subsequent farming extractions it is nothing but voodoo.

    It seems that Kingsford had better contact his bosom buddies over at the ‘Wentworth Group of Disturbed Scientists’ for the reason that these highly distressed people know absolutely everything there is to know about the Murray/Darling Basin. They say: “In 2008 the Wentworth Group with other scientists put forward an Interim Basin Plan as a model for excelerating water reform across the Murray-Darling Basin in a senate…”

    However, finding the time to do this will be hard given that being an amateur pre-cautionary expert prosecution witness takes a lot out of the good professor.

    Yes, PAYG, it is now quite clear that no-one associated with the "Witless Group of Corrupt Scientists" is a fit and proper person to have any part in the policy process.

    They failed to recognise the yield and vegetation gains and losses from the original clearing in the Basin and then compounded their negligence by failing to recognise that much of the so-called losses from irrigation extraction merely cancelled the earlier clearing related gains.

    This is damning evidence of a serious lack of core analytical competencies and they have squandered their right to inform policy.

    That's right - too many unknowns. So why does Dr Kingsford-Smith keep insisting that we need 4,000GL plus for the river if he doesn't know what impact it will have? How bout they just see if they can work with the 1400GL plus they already have and see if they can actually achieve anything before destroying regional communities. But they wouldn't do that because that would mean using common-sense instead of their questionable intelligence.

    By 31 December South Australia will have received 14 million megalitres for 2011 which is twice their long term average. And that is why the MDBA is very reluctant to revise their flow data to incorporate non-drought data.

    And what is there to show for this annual 14000GL of flow? Check out the salinity levels in the Coorong, Parnka Pt, EC80019 and Cattle Island, EC 110,761 (more than double the salinity of sea water) http://data.rivermurray.sa.gov.au/Telemetry/Default.aspx?App=RMW

    Even double the claimed fresh water volume won't fix the underlying problem of a closed system.
