Billionth seed banked

The Guardian reports that the Millennium Seed Bank at the Royal Botanic Gardens, Kew, recently deposited the billionth seed in its genebank. Note, that’s not a billion species, or even a million, but the billionth seed ((Which is to say, an entirely manufactured reason, which worked, for getting a bit of press coverage.)). Normally such blatant manipulation would be beneath our exalted notice, but Kew wisely chose a useful plant on which to bestow this singular honour.

  • In parts of Tanzania women depend on this species for local beer production as a major source of income.
  • It is used to make various types of local baskets for transporting produce, such as tomatoes in Iringa.
  • It is in high demand as a building material. It is used for scaffolding, furniture, general house construction, and fencing. Fences are susceptible to damage by termites and borers. The small stems are used for pipes and arrow shafts

All from FAO, which does not seem to think it is all that endangered. Still, Kew thinks it is worth banking, and that’s good enough for us.

Perk up people, it’s about your survival

Someone called Bradford Plumer, whom I had not previously come across, has a longish post asking why people don’t seem to care about the ongoing mass extinction and wishing that more writers on the subject “would really hammer home why humans should care about the loss of biodiversity”. Funnily enough, he couches his entire argument in terms of natural processes and ecosystems and what their collapse might mean. And he quotes agriculture, and especially monoculture, exclusively as problem, not solution. But the only example he gives of the sort of example that might might “get people to perk up” is the possibly looming pollination crisis caused by a shortage of bees.

Until there is a wider understanding that agriculture is part of nature, and not separate from it, and that we humans are far more dependent on the food providing services of agriculture than on any other ecological service, I doubt that there’s going to be much perking up anywhere.

There’s not a lot of understanding of that in Brad’s posts or the comments on it, but I live in hope.

Science weighs in on biofuels

Donald Kennedy, Editor-in-Chief of Science magazine, thinks there is a “biofuels conundrum”. He agrees that growing corn for ethanol results in huge distortions and problems elsewhere. Ethanol from sugar cane is better, but blocked by corn-state Senators in the US. Palm oil, as biodiesel, is better yet, but still carries considerable downsides. So, Kennedy says, we need more investment on research into biofuels derived from cellulose. Fair enough. But not a single mention of actually reducing consumption of liquid fuels. Not one word. I guess Kennedy, like so may others, isn’t quite ready to sign the bio-temperance pledge.

Investigating the bee shortage

The New York Times has a fascinating article about the shortage of bees caused by colony collapse disorder. Bees Vanish, and Scientists Race for Reasons is that rare thing in science writing, a story about process rather than results. So there’s not a lot actually to say, other than noting that around 60 experts gathered for a two-day meeting to assess the possibilities and plan their investigations. The most likely suspects — according to these mainstream scientists — are “a virus, a fungus or a pesticide”. Not cell phones. We shall see.

Are Kenyans ignoring diversity of diet?

A long press release from Tufts University in Boston, USA, tells us how faculty members have assisted Kenyan policy-makers in a series of workshops

“to build strategies for implementing Kenya’s National Food and Nutrition Policy. … The scope of the plan ranges from agricultural production, strategic grain reserves, and post-harvest protection, to nutritional interventions for high-risk groups, and the interrelationship of nutrition and diseases such as malaria, tuberculosis and HIV/AIDS.”

But I see no mention whatsoever of either dietary diversity or the value of local species as a contribution to nutrition. I’m hoping this is just an oversight by whoever wrote the release, but I fear it may not be. Using local food diversity to boost dietary diversity has so many benefits, I can’t imagine how the team overlooked it.
