UK’s leading Permaculture author Patrick Whitefield posted an interesting tweet the other day:
If people suggest we need GM to counter potato blight, let them read this. http://t.co/kD3IwIoScv

to which I replied:
@Skepteco My point was we don't /need/ gm blight-res potatoes. We could have both but it's not a need. It would be a choice.

It seems a strange argument- how does one define “need” in this case? A new technology that can save large losses from disease seems something certainly desirable- and ultimately we may well need it to make farming more efficient. Even if we do not currently “need” GE spuds, the technology has many other applications and developing countries where food security is not so, well, secure, really do need such improvements for their farmers.
One specific but quite different application of the technology is of course Vitamin-A enhanced Golden Rice. With hundreds of thousands of vitamin-A deficient children becoming blind each year, and half of them dying within a year, this rice would indisputably be meeting a very urgent need which other methods are clearly not meeting. To claim otherwise is “just noise.”
Genetic engineering does have significant advantages over traditional breeding methods- new blight resistant varieties can be turned around in just one growing season as opposed to 10-15 years, keeping ahead of the blight’s own evolution. Either way, we are on a tread-mill, always striving to keep at least one step ahead of Nature who would starve us as soon as look at us. Moreover, a wider choice of tools surely leads to more resilience- just as the permaculture principle of “multiple sources” would advise.
You may as well say we don’t “need” computers since the postal service does an admiral job, or we don’t need buses and trains since the humble horse can carry us to Tipperary just as well. On the face of it is just seems like an excuse to undermine a technology which is somewhat arbitrarily the subject of a vitriolic environmentalist campaign. The clue comes in the last paragraph of the linked article:
Ultimately, the array of techniques currently in practice among commercial growers to prevent potato blight makes the need for a GM solution appear redundant and potentially reckless, especially when considering the broader implications of resistance, pesticide-use, and corporate ownership of our food systems.
Ah yes, playing the “corporate ownership of the food system” card- which rather conveniently serves to cover up the absence of any actual argument against GMOs in the article, even if some growers do find Sarpos preferable.
I challenged Patrick that his opposition was ideological, and he didn’t really have any argument. He disputed this- “For me this is not a matter of ideology but of practicality, of weighing pros and cons.”- and went on to make a point:
@PatrickWhitefi but Bt is used as spray in Org farming, also leads to resistance; ALL weed/pest controls >selection pressure and resistance

Again, this seems an odd argument- as if a solution cannot be used if it works really well, because if it works too well it won’t work very well. If you get my drift… In my view, this is just a concealed concession to fears of Pandora’s Box: we should not trust technology. We are too clever for our own good. No good in fact will come of this, since we just shouldn’t be meddlin’ in what we don’t really understand. That is what I mean by ideology- the misanthropy that underpins much environmentalism, including permaculture, that basically would shake its head in dismay at the Knowing Ape and say: People just ain’t no good.
In the real world there are actual farmers who know about these things, and have well known techniques to help slow the evolution of pest resistance, for example by planting corn refuges. As with so many issues raised in objection to GMOs, this is a farm management issue, not a plant breeding issue.
In fact, although resistance is an inevitable result of any kind of pest control method- that ol’ treadmill again- the reality is far more interesting. It turns out that the unintended consequences of for example of Bt corn in the US are of the beneficial kind- is so successful that it can actually provide a refuge for non-transgenic varieties. The halo effect is best known in the Rainbow Papaya in Hawaii, credited with saving the Organic Papaya industry which was being devastated by ringspot virus- again, traditional methods had proved unable to solve the problem, so there an indisputable (but not undisputed) need:
In the case of the Hawaiian papaya, scientists planted an “island” of nontransgenic variety in an “ocean” of transgenic papaya as a means of securing the nontransgenic variety. The specially modified traits of GM crops helped to kill off pests, control water intake and provide a sort of refuge for non-modified crops in nearby acres.

Open-mindedness is a very welcome quality in this highly politicized and ideological issue. For Patrick Whitefield to even claim this is big bananas in permaculture world, since he is one of the top writers for the UK Permaculture Magazine, which has taken an overtly activist position against GMOs, and regularly fetes Indian ideologue Vandana Shiva .
(For an must-read in-depth look at what Vandana Shiva really stands for see this article by Marco Rosaire Conrad-Rossi.)
Most bizarrly though, Patrick ended the exchange by saying that it was me who is closed-minded!
@Skepteco You've researched this more than I have, so if you see our exchange as a contest you win. But its sad your mind's so closed on gm.
— Patrick Whitefield (@PatrickWhitefi) April 11, 2014
I suggested to Patrick that he write an article on GMOs for the magazine, arguing for an open-minded approach. This I think would be rather a stretch- but one can live in hope.
