Birds not so smart after all?

Hold the phone! A press release informs us that over two winters, using two different varieties of wheat, garden birds and lab canaries preferred conventional over organic grain. And the reason seems to be that the conventional grain contained 10% more protein. Very smart! But before word goes out to the birds of the world, consider what else the press release says:

This study is only looking at one aspect of the organic food debate – it does not take into account the long-term health implications of using chemical fertilizers and pesticides, or the often negative environmental impact of conventional farming; for example, other work has shown that pesticides can strongly reduce availability of seeds for birds. But it does raise questions about the nutritional benefits of organic food and what consumers are being led to believe.

Because consumers in the UK are choosing organic for its higher protein levels? Because they’re short of protein? More to the point, has anyone asked the birds to consider the long-term consequences of their choices, like the reduced availability of seeds, or nesting spots, or insects for their insectivorous feathered friends?

And, let’s not forget, increased levels of carbon dioxide are reducing protein levels in wheat. Another good reason to grow conventionally, whatever that means.

International Day for Biodiversity in Nairobi

If you’re in Nairobi, Kenya, next Saturday 22 May and you feel like celebrating the UN’s International Day for Biodiversity in this, the UN’s International Year for Biodiversity, you could do worse than pop along to the National Museum of Kenya’s Louis Leakey Auditorium for the first Nairobi Agrobiodiversity Debate. Kick off is at 11.30 a.m., and this is what you can expect, according to the organizer’s website:

Hans R Herren, an internationally recognized scientist and current president of the Millennium Institute (Washington, D.C., USA), will be the key note speaker. Hans’s fellow panelists will include Professor Steven Gichuki, Dean, School of Environmental Studies Kenyatta University and Patrick Maundu, an Ethnobotanist with National Museums of Kenya and Honorary Research Fellow with Bioversity International (Kenya and Dr Balakhrishna Pisupati from UNEP along with a few more special guests. The Nairobi Agrobiodiversity Debates will be moderated by our very own Dr Toby Hodgkin, Coordinator of the Platform for Agrobiodiversity Research and Principal Scientist with Bioversity International (Italy).

We’ll gratefully accept any first-hand reports.

Diversity and adversity in Yunnan, China

It can be a bit frustrating banging on about the importance of agricultural biodiversity when almost everybody else seems to be focused on simplistic solutions to complex problems. Frustrating, and tiring. So I’ll just point you to two items you can read for yourself and decide whether we are truly nuts. First, Nature’s report from Yunnan in China about the drought there. Secondly, a paper by Professor Yy Zhu and his colleagues, Crop Diversity for Yield Increase. Anyone should be able to join the dots.

GM research: is there no alternative?

Some strange juxtapositions lately. On the one hand, we have Bruce Stutz writing in the Yale Environment 360 that private companies working on GM crops remain reluctant to allow independent research on their products. On the other we have Pamela Ronald and a colleague opposite the editorial page of the New York Times, saying that we need lots more GM, preferably in the public domain.

I don’t know enough about the intrigues around independent research to say more than that it seems pretty rum that scientists can’t get their hands on the stuff they need to assess GM crops for themselves, as opposed to for the manufacturers. Pamela Ronald’s arguments are, however, a lot more filling. And a lot less convincing. For example, she talks about engineering sorghum resistant to drought and to the parasitic weed Striga. Before we worry too much about drought-resistant sorghum, though, might it not be a good idea to just help farmers move from their very thirsty maize crops to the altogether more frugal sorghum? And is there really a need to engineer Striga resistance when a locally proven simpler technology already works perfectly well and tackles more than one pest, in more than one crop? It isn’t glamorous. But it works. Now. Not at some unspecified time in the future. Golden rice puts in an obligatory appearance, and there are cameo walk-ons for high-protein potatoes and high zinc sorghum. In other words, the usual suspects.

What is novel is that Ronald, who engineered flood resistance into rice, and her co-author James E. McWilliams, devote most of their space to the papaya engineered to resist ringspot virus, which saved the papaya industry on Hawaii. They say that:

The real significance of the papaya recovery is not that genetic engineering was the most appropriate technology delivered at the right time, but rather that the resistant papaya was introduced before the backlash against engineered crops intensified.

I don’t think that is its real significance at all. I think its real significance is that it shows what a dedicated individual researcher — Dennis Gonsalves — can do when not working for The Man. I know this not from Gonsalves himself, but from a blogger’s write up of a talk Gonsalves gave, which we nibbled here a couple of weeks back. There are some interesting insights there into the differences between public and private research, which is why I found this paragraph from Ronald and McWilliams so interesting:

As it now stands, opposition to genetic engineering has driven the technology further into the hands of a few seed companies that can afford it, further encouraging their monopolistic tendencies while leaving it out of reach for those that want to use it for crops with low (or no) profit margins.

That really is one of those nice counterfactual propositions. Why is it out of reach? Because of the cost of regulation? In which case, could it be that the cry of the private companies against the time and cost of regulation is really crocodile tears? Maybe it really suits them, because only they have sufficiently deep pockets. I wonder whether public opinion would be more favourably disposed to genetically engineered crops if they were produced as public goods, to be distributed at cost to the deserving poor? Is it just profit that makes GM crops unacceptable, no matter what people might say about health or the environment?

Papaya ringspot resistance might be OK, because there is no alternative. But for “problems” where we already have perfectly good solutions, I don’t believe it matters whether that research is in private or public hands. The pure financial cost is too high, especially when we haven’t invested enough in the alternatives.

A market in agrobiodiversity conservation credits?

So apparently Caroline Spelman, the new UK Secretary of State for environment, food and rural affairs, will be considering “a new system of conservation credits to protect habitats,” in line with a manifesto promise.

Under the scheme proposed in the manifesto, any property development that results in biodiversity loss must compensate for that loss by an equal investment in biodiversity and habitat conservation or restoration elsewhere.

Or so says a generally favourable commentary in The Guardian by Ben Caldecott, head of UK & EU climate change and energy policy at Climate Change Capital (CCC), who actually thinks the whole thing should go global. Worth a try, why not? But will the scheme include agrobiodiversity? If the said property development, or whatever, resulted in loss of genetic diversity in crop landraces or local livestock breeds, would it likewise be brought to book? It would be nice, though perhaps naive, to think that it would.
