Thou shalt not build dams - ever!

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. 

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.
