- A third take on dog origins. Lock them all up in a small room and don’t let them out until they figure out a way to solve this. And more.
- Great new maps of deforestation. Same as the old maps? I’m confused.
- Ah, to be able to mash them up with crop wild relatives gap-maps! Or others, for that matter…
- Clear, balanced take on how to fix the food system. (And a great potted summary of why it is necessary to do so by the sainted Lawrence Haddad. The interviewer is not bad either.) Except maybe for the bit which sort of implies that the only way to improve crops is via GM. And for the other side…
- Bioversity comes up with a strategy for community seed banks in Limpopo and other areas of South Africa. Coincidentally, another CGIAR report on the same region, looking at wider food security issues. I wonder if the two could/should be mashed up? But really my main reason for linking to the second thing is to see how many people read the title as a plea for a return to old-fashioned cartography, as I did.
- Dual-purpose maize, shmaize. I just love that building.
- Latin American consortium looking for potatoes and wheat varieties adapted to new climatic conditions. Amazing that it is news, in a way.
- Global Tree Campaign launches new website. Sill no RSS feed though, that I can see. LATER: Here’s the feed, sorry to the GTC!
- Speaking of trees… Will agricultural intensification save tropical forests? Well, maybe. Demand elasticity comes into it, apparently. Dismal science indeed. I suppose those maps above come in useful for this kind of thing?

- That “tearless onion” is good for the heart story? The article is behind a paywall, so I don’t know how the boffins suppressed lachrymatory factor synthase. And frankly, I don’t really care.

- French seed company Vilmorin buys 25% of Zimbabwe’s Seed Co. Ltd. What could possibly go wrong?
- “Katy Perry’s latest album, Prism, is Number One in Australia, but that hasn’t stopped the country from declaring it a potential biohazard.” Can anyone explain the significance of this story? Or who Katy Perry is?
- On the whole, I’d rather be at the frites museum in Bruges.

Luigi went on a three-week trip, and all he came back with was this:
- A new soil testing kit? Really?
- Ok, how about a SciDev Spotlight featurette on sustainable farming? No? Well, can I tempt you with the British Ecological Society on agroecology then?
- Oh, I bet this thing on coffee and climate change will hit home.
- I’m pretty sure news of yet another Chinese genebank (of sorts) won’t.
- Pssst. Got room for a new bamboo genebank too?
- They’ll need a genebank management system, won’t they? GRIN and bear it.
- News too of hunger and malnutrition in India, by Indians, for … er …
- Phenotyping conference, anyone? Anyone at all? Some EU breeders will no doubt be there. And some of them at least will find a new map of water risk useful in their work.
- And to end with, Al Jazeera on the CIP potato genebank. You heard me.
- As you were, there’s the CGIAR Knowledge Day too, all about delivery and impact. I wonder if the genebanks will feature…
- Not so fast, there’s also a live webcast of the conference Feeding the World without Consuming the Planet that awaits you.

Stop vitamin A supplements
The editorial by Thorne-Lyman and Fawzi in 2011, (1) referring to the meta-analysis of the impact of vitamin A supplements by Mayo-Wilson, Imdad and others, (2,3) has now become more important than ever. The DEVTA results, only informally available in 2011, have now been published, (4) with extensive implications; indeed, as the editorial (1) says: ‘… the null findings have left lingering questions. Is vitamin A supplementation effective?’. These results have been the subject of conflicting comments recently in the Lancet, e.g. (5,6). But a number of inferences that should be drawn from the compilation and analysis of the evidence from trials prior to DEVTA (2,3) help answer this lingering question, and have not received adequate attention. There are three key related points, which now point to the need to seriously consider concrete steps to move beyond 6-monthly vitamin A supplementation at unphysiological levels.
OK, there’s a lot in that introduction to a recent paper in the British Medical Journal to digest, but it is worth it. I know I bang on about the colossal boondoggle that is high-dose vitamin A supplementation, but there’s a reason. It seems to be a complete waste of money based on a very limited reading of the evidence. In 2011 the BMJ published an editorial on Improving child survival through vitamin A supplementation (which is behind a paywall) that referenced a meta-analysis of supplementation. The new paper — Is vitamin A supplementation effective? — brings things up to date with a more detailed analysis of some of the research only hinted at in the original articles. Bottom line: there is no evidence for large-scale effectiveness of vitamin A supplements on child mortality.
As the authors of the rebuttal ask, why are resources still going into supplementation campaigns of the old sort? And they conclude:
Improved diets, fortified foods, and multiple micronutrient provision would surely bring broader improvements in nutrition to more people, including reproductive aged women who are now largely excluded.
