As a conventional arable farmer with a deep interest in birds, I struggle with the arguments of the organic lobby. Even though I have a brother with organic ground - and I support his activites 100%.
There seem to be serious questions over the environmental credentials of organic farming, and nobody has answers.
1. In Western developed agriculture, where labour is short and machinery use predominates, is there any reduction in fossil fuel use ? Weeding takes so much energy that this appears to be dubious. This is compounded by point 2b.
2. Yields are lower, so
a) much more ground is required. Is environmental damage worse because so much more land is affected ?
b) shouldn't measures be made per tonne of usable product, rather than per hectare ?
3. Does weeding knock hell out of ground nesting birds ?
I think that Organic farming is trying to ride the environmental bandwagon. The objectives of Organic farming are not primarily environmental, but economic. I strongly believe that no system consistently meets objectives unless those are explicitly stated and audited against. In the current set up, I would not expect Organic farming to be particularly environmentally friendly.
As a spin off, I think Organic farming may have benefits. These arise from the fact that Organic "arable" farming forces a more diverse rotation, and can afford to sustain it. Other systems are not excluded from using rotations, so we could find other ways to achieve those benefits, along with many others.
For environmental benefit I think the best way forward would be to gain greater returns for systems which set specific objectives and audit against them. It sounds to me like LEAF might meet some of my criteria.
GMOs ? I have argued about these before. Tom talks about pressure from the US for, pressure from EU consumers against. I don't think that is quite right. I think the pressure for is from big business, which is multi-national, but happens to "own" the US government. Pressure against is from pressure groups, who successfully manage to generate an image of widespread resistance which they may or may not have succeeded in generating. I don't know whether this distinction from Tom's analysis would be important, if I am correct.
As usual in such debates I believe that most of the "evidence" presented by both sides is tosh. How are we supposed to work out the best position when we cannot obtain reliable evidence ?
My take on GMOs is that I believe they offer real benefits, but that the ones I have heard being grown are, perhaps without exception, taking a risk unnecessarily.
What is wrong ? The problem goes back to governments' total abdication of their responsibilities - to serve ordinary people. they have passed those responsibilities on to big business, who (quite rightly) serve their shareholders. GMOs have been developed in that climate. High costs of development mean that only those which have a large potential market are of interest. If they are going to be widely marketed, the pressure on the environment is potentially large, giving a high risk of problems. On the other hand, benefits should ultimately be measured from the ordinary person's perspective. What are they ? Umm, well ...
GMOs should be being used to solve real problems for the common people (minf what I said about setting objectives ?). The problems that remain in the west tend to be the exact opposite of what the current GMOs attack. This is hardly surprising, there is a specific class of problems which give a return on investment. The others will have to wait. Problems which GMOs _should_ be considered for are those which are too small to be economic to attack conventionally. A good example would be beta-interferon for MS. Small market, exorbitabtly expensive drug. The National Institute for Clinical Excellence has tied itself in knots before recommending this treatment because the cost, potentially, could be disastrous for the NHS. I strongly believe the government should fund research into cheaper production methods, I would put GMOs at the top of the list of possibilities. The environmental impact assessment would almost certainly show vanishingly small risk because the active ingredient is specific to a rare human condition, and the quantities required would be small, so GM crops would not be widespread, and length of time grown in any area could be severely restricted.
We need to clear away the emotive invective, think clearly about objectives (allowing for cost and benefit) and processes and funding to get there. Our present management of this country is laughable.
Yes, I am simplifying an incredibly complex situation. But I have said enough :-)
