Overlooking agricultural biodiversity again

I’m afraid I’m going to be a nay-sayer again. Here’s a quote from an otherwise very worthy piece on the Gates Foundation website trying to link what’s happening at the G20 and in the CGIAR reform process and other high-level stuff with the needs of “35 year old Oumou, who lives in Sadore village in Niger, struggling to feed her 5 children due to unpredictable harvests from her husband’s millet farm.” ((Note, by the way, that Sadore is where ICRISAT has its Sahelian Centre, and if anywhere in Niger should be benefiting from agricultural research, it is there.))

…Oumou’s group could plant hardy Apple of the Sahel (10 times the vitamin C of ordinary apples and rich in calcium, iron, and phosphorus) and Moringa trees (whose leaves contain 4 times the vitamin A in carrots, 4 times the calcium and double the protein in milk, and 3 times the potassium in bananas).

I don’t have much of a problem with the use of a vernacular name for Ziziphus in such a piece. You might ask why use Moringa then, but that seems to have become widely accepted as the common name for Moringa oleifera. What I do have a little problem with is comparing its vitamin C content with apples, a crop that is of no relevance to the Sahel. But that’s a rhetorical flourish on the part of the writer, I guess. Apple of the Sahel vs ordinary apple. Geddit? Let’s let that pass.

I personally think “10 times the vitamin C of ordinary apples” is borderline misleading, even if it were a useful comparison, though that is excusable too. Quick googling gave a range of 44-133 mg/100g pulp for a few “ber” varieties and 7-40 mg/100g pulp for a few apple varieties. So the range of ratios is about 1-20, so let’s call it 10 on average. Fine. But who cares about averages? In a piece about how research can help the Sahelian smallholder, why not grasp with both hands the opportunity of at least pointing out that Oumou could be helped to identify the most nutritious varieties? Dropping the agrobiodiversity ball — no, that’s not it: not even recognizing it as a ball — is what I find it hard to forgive.

Money for shiny new rope?

You might think that when Africa’s “most important, but neglected native crops” get $40 million of support we would be all over the story like a rash. So why weren’t we? ((It isn’t just because hard information is surprisingly difficult to find, although UC Davis might want to fix the link on one press release. Likewise, it would be really handy if The Clinton Global Initiative (CGI) actually linked to the “commitments” delivered at it’s jamboree last week. Colouring them blue and underlining them is apparently of no significance. And it isn’t just because, like our friends at Crops for the Future, we can’t figure out what some of these crops actually are.)) Mostly it is because it is really hard to find anything positive to say, and we don’t want to sound like nay-sayers.

The gist of the “commitment” Improving Africa’s Neglected Food Crops, which the Clinton Global Initiative ascribes to NEPAD, the New Partnership for Africa’s Development, ((Find it there if you can.)) is that private companies and public bodies have teamed up to build, among other things, a biotechnology centre in Ghana. According to UC Davis, the centre:

[W]ill sequence the genome — an organism’s entire collection of genes — for each species and make that information freely available to scientists around the world. That information will then be applied, using the most advanced breeding techniques and technologies, to develop new varieties of crops that are more nutritious, produce higher yields and are more tolerant of environmental stresses, such as drought.

The proposed centre may even be the same one referred to in a SciDev.net piece, although that one “will focus research on cassava, cocoyam, sweet potato and yam”.

Either way, I have to ask whether complete genome sequences are what poor African farmers really need right now. I realize that genomes are groovy, and very scientific, and will undoubtedly deliver great improvements in five years. Right now, though, here’s a small idea of what actual smallholder farmers want. Yesterday morning — I promise — Nduse Mailu left this comment to a post from March 2007:

i stumbled on this blog abd it seems quite awesome to a farmer like me.i currently have about 500 trees and i am in the process of increasing to 4000 and i am seeking guidance on whether to continue growing kienyenji style that is planting seeds from my own fruits or profesionaly that is buying guide me please and to Victor how are your trees doing what are ur challenges if any?

As it happens, the announcement of the new project singles out a tree for special mention.

[T]he consortium has already begun to sequence the (sic) Faidherbia albida, a type of acacia tree that can be used for improving soil nitrogen content and preventing erosion. The tree also has edible seeds and, unlike most trees, sheds its leaves during the rainy season so that it can be grown among field crops without shading them.

Right now, then, what do you suppose Mr Mailu needs? The sequence of Faidherbia albida (aka African winterthorn) with a promise of great improvements to come? Or a reliable supply of seedlings of good enough provenance and the knowledge to get the most out of them? ((Here‘s a start.))

I have no desire to stop Ghana and the rest of Africa developing the skills to sequence whatever they want, although I do question the cost effectiveness of doing the sequencing that way. But why is it even possible to talk of raising $40 million for that when farmers like Mr Mailu are posting comments here looking for very simple advice?

Here’s one possible reason.

“In order to really solve problems, and to get people to join, you have to break them down to their most transparent and simple pieces.”

So says Rajiv Shah, “the young gun fixing USAID” in an interview he gave Fortune magazine. And that idea — simplify, simplify, simplify — Shah got from his mentor Bill Gates, who said:

“The barrier to change is not too little caring; it is too much complexity.”

Uh-huh.

Now, you can take two approaches to the kind of complexity that faces Mr Mailu and millions like him. You could say that providing comprehensive extension services to millions of poor farmers is impossibly complex because the farmers all live in different places and have different farming systems and need different advice. How much simpler to sequence orphan crops.

Or you could say that sequencing orphan crops is unutterably complex, because each crop is likely to be different and to require different tweaks to its genome to enhance its performance in different places, and in the end you’re going to need massive investments in extension services to get the improved crops out to the farmers and ensure that they know how to make good use of them. How much simpler to offer farmers good practical advice now.

How complex is that?

Feeding you information about feed

The CGIAR’s Systemwide Livestock Programme ((Wait, there are still CGIAR systemwide programmes?)) has just announced the release of its latest database, this one on the nutritive value of feeds in Sub-Saharan Africa. You put in the name of some sort of feed, typically a plant species, and you get out data on nutritional composition, often from multiple samples, arranged in a couple of different ways, and downloadable. Nice enough, and very useful, I’m sure, for its target audience. However, at the risk of burnishing to a well-nigh mirror-like finish my reputation as a nay-sayer, I’d have to say that I missed a couple of things. One would be the ability to search on particular nutritional values. Then when a species with the appropriate combination of qualities pops up you could work out if you can grow it in your shamba using another nifty ILRI tool. And the other thing would be some kind of link to genebank accessions. Surely some of the samples analyzed were of material that’s conserved in the ILRI forages genebank? Maybe for ver. 2.0.

  • NSF re-invents the genebank wheel. No, that’s unfair, they’ve given much-needed money to evolutionary scientists to go out and collect seeds of 34 species in a really pernickety way.
  • Heirlooms being lost (maybe) and being re-found in the US. Thanks to Eve (on FB) for both.
  • A Cape tomato by any other name…
  • Gates Foundation has a new nutrition strategy. Gotta admire the chutzpah of summarizing the thing in basically half a side of A4. Compare and contrast, both as to content and presentation, with the CGIAR. Unfair again, I know, but that’s the kind of mood I’m in. Jess unavailable for comment.
  • Very complicated, very pretty maps about potatoes and climate change.
  • “I failed to notice substantial contributions to discussions or presentations from breeders or seed organizations, the end users of so much of the research discussed.” Pat Heslop Harrison calls ’em like he seems ’em.
