The Queensland floods have caused tragic loss of life, vast damage to infrastructure and will cost several billions of dollars. They are among the worst floods in Australia’s twentieth century history. Similar devastation occured in 1918, 1954 and 1974. I know a couple of farmers ‘up north’ and one tells me that after a bad drought comes a bad flood. He adds that this is followed by a couple of good years with ‘bumper crops’. He might be right – I don’t know. At least he is offering a testable hypothesis.
What I do know, though, is that the floods will generate a much-needed public discusion, and hopefully a debate, about the role of dams in flood mitigation. No new dams of significant size have been built in Australia for about three decades. During the recent long drought, the ’dam’ question arose again but the response from experts and governments was along the lines of ’Why build a dam if the climate has permanently changed in a way that means there will be less rain in future?’.
Opposition to dams has been a key success in the development of the Green movement and its party since the early 1980s. But to use the term “opposition” understates the situation: it is really ‘demonization’ of dams. In the Green quasi-religion, dams are evil, akin to a Satanic force. Thus, there must NEVER be any new major dams built. Not ever. The Green policy is expressed at their website as a principle: “There should be no new large-scale dams on Australian rivers”. http://greens.org.au/policies/environment/water-inland-aquatic-environments
Had the Greens been as influential in the second half of the 1970s as they have been since the mid 1980s, it is unlikely that the Wivenhoe Dam, on the Brisbane River, 80 kms from Brisbane, would have been constructed (after years of planning and building, it was opened in 1984). The Wivenhoe was designed, following massive floods in 1974 (on current indications, worse than the present Brisbane flooding), with a flood mitigation function alongside the usual water supply role. Like all dams, it is an example of human beings changing the natural world, by unnatural means, into something very useful and necessary to us in terms of our needs, standard of living and future progress.
During the terrible Australian drought, the Queensland Government moved to build a new dam on the Mary River, the Traveston Crossing Dam. It was seen as necessary to providing reliable water supply to Brisbane. Opposition to it, spear-headed by green activists, was successful and the Traveston dam was never built. Given that the drought had been so severe and gone on for so long, back then the argument that there might not be enough rainfall to justify such a large dam carried some weight to many people. But there were also those who argued convincingly for it and it was only halted because of a decision by the Federal Minister for the Environment in 2009 who was worried about the loss of endangered species (a lungfish, a local turtle and a local cod). In the recent floods, the Mary River peaked (at the town of Gympie) at over 19 meteres. What would have been the flood mitigation impact had the Traveston Corssing Dam been in place?
To the Green mentality and ethos, changing Nature is destroying Nature, dams are an assault on the ‘delicate balance’ in Nature, an example of human arrogance going ‘too far’. In this regard, the Green mentality and ethos are quasi-religious. The late Michael Crichton put it neatly in a speech to the Commonwealth Club in San Francisco in 2003 when he talked of the ”remapping of traditional Judeo-Christian beliefs and myths’. He said:
There’s an initial Eden, a paradise, a state of grace and unity with nature, there’s a fall from grace into a state of pollution as a result of eating from the tree of knowledge, and as a result of our actions there is a judgment day coming for us all. We are all energy sinners, doomed to die, unless we seek salvation, which is now called sustainability. Sustainability is salvation in the church of the environment. Just as organic food is its communion, that pesticide-free wafer that the right people with the right beliefs, imbibe. Eden, the fall of man, the loss of grace, the coming doomsday—these are deeply held mythic structures. They are profoundly conservative beliefs.

It’s good that he identified them as ‘profoundly conservative beliefs’. They are very reactionary beliefs.
As has been pointed out many times at this site, it is indicative of our strange times that opposition to dams, as a matter of principle, can be seen as left-wing. What is the traditional practice of left-wing parties in power on this question? What is the left-wing theoretical foundation for a policy on dams?
In practice, revolutionary left-wing parties in power – such as the communists in Russia/Soviet Union in the 1920s and 1930s and China in the 1950s and 1960s - were gung-ho in the building of dams. They did so because making a revolution is about changing things for the better, raising the standards of living and opportunities for liberation from wage slavery. To borrow from Karl Marx, it’s about ‘unleashing the productive forces’ – not forcing them into a sustainable relationship with Nature. It’s about an attitude based on “You ain’t seen nothin’ yet!” - not ‘tread gently – Nature’s resources are finite’. But this is ‘red’ politics, not green. The Chinese revolutionary Mao Zedong was so into dams that in 1956 he wrote a poem about his dream for the Yangtze:
“Great plans are afoot:
A bridge will fly to span the north and south,
Turning a deep chasm into a thoroughfare,
Walls of stone will stand upstream to the west
To hold back Wushan’s clouds and rain
Till a smooth lake rises in the narrow gorges
The mountain goddess if she is still there
Will marvel at a world so changed”.
In chapter 1 of The Communist Manifesto, Karl Marx expressed his enthusiasm for the revolutionary consequences of the rise of the new bourgeoisie in transforming Nature and extending human horizons. He said:
It has been the first to show what man’s activity can bring about. It has accomplished wonders far surpassing Egyptian pyramids, Roman aqueducts, and Gothic cathedrals; it has conducted expeditions that put in the shade all former Exoduses of nations and crusades.
It is unlikely that he would not have been as awe-inspired by the wonders of large-scale dam construction and the range of benefits on such a vast scale arising from dams: the capture and storage of safe and reliable water supply, generation of hydro-electricity, irrigation, flood mitigation and recreational uses (all on a scale unimaginable in Marx’s time).
The Wivenhoe Dam on the Brisbane River worked effectively in mitigating bad floods around Brisbane in 1999 but, alas, despite its 1.4 million megalitre flood mitigation capacity (on top of its water supply capacity of 1.1 million megalitres) it could not stop the extensive damage that occured during the current floods. And to return to the opening point of this article, there needs to be debate about all this. To what extent did the Wivenhoe mitigate the flooding of Brisbane? How much worse would it have been without that mitigation capacity?
There is good stuff on this at Catallaxy http://catallaxyfiles.com/2011/01/11/would-dams-reduce-flooding/
I know that it will be argued that dams are ‘so 1950s’ but that is not an effective argument unless the proponent can offer something new and better. And, no, the state imposing compulsory water storage tanks in homes is not something better. I live in a trendy inner city suburb and a few of my neighbours have multiple storage tanks in their gardens, a reflection of their susceptibility to climate change alarmism. (They no longer have that glow of self-righteousness about them but will no doubt keep the tanks in place).
An area that interests me greatly is geoengineering and its possible roles in controlling rainfall. I have no expertise in it or in hydrology. But I do know about politics and the politics that declares, as a matter of principle, that there must be no new large dams is a dogmatic, conservative and reactionary politics. It is highly unlikely that adherents of such green politics would support greater funding for research into geoengineering solutions - indeed, geoengineering is abhorrent to them – let alone new dams with enhanced flood mitigation capacities, as appropriate in flood prone regions.
It always strikes me, when these issues arise, how backward the social system of capitalism really is. Human lives and billions of dollars are lost yet only a pittance is invested into research and development into geoengineering, let alone dams, and even that is contested by the reactionaries.
