In the land of serendip

Luigi briefly drew attention to the latest offering from our friends at Climate Change, Agriculture and Food Security: the Adaptation and Mitigation Knowledge Network. And that — along with all the other maps that seem to have been springing up whenever one’s back is turned — reminded me of a map passage from a little-known Lewis Carroll book, Sylvie and Bruno. ((Well, little known compared to Alice, say.)) Looking for the exact quote, I discovered that it had appeared yesterday in the daily blog of the august Paris Review. ((The internets are a wonderful place, except when they aren’t. And the whole post is worth reading.))

Toward the end of Lewis Carroll’s endlessly unfurling saga Sylvie & Bruno, we find the duo sitting at the feet of Mein Herr, an impish fellow endowed with a giant cranium. The quirky little man regales the children with stories about life on his mysterious home planet.

“And then came the grandest idea of all! We actually made a map of the country, on the scale of a mile to the mile!”
“Have you used it much?” I enquired.
“It has never been spread out, yet,” said Mein Herr. “The farmers objected: they said it would cover the whole country, and shut out the sunlight! So we now use the country itself, as its own map, and I assure you it does nearly as well.”

Revisiting the passage in question, I discovered that it involves farmers, which entirely justifies me using it here. My real purpose, though, was to disagree gently with Luigi’s complaint that “You can’t really share the AMKN maps” Why would you want to? The map, after all, is little more than an index, like at the back of a book, that adds geography to content to help you find something you’re looking for.

If I wanted to draw your attention to a bit of a book, I wouldn’t point you to “line 36 on page 304” when that’s the entry in the index. I’d point you directly to page 211, where the bit in question resides. Same with the map. Why embed a bit of the map, when all it really does is point you to content elsewhere?

I had hoped there’d be something in the map around Baku, which I would then have taken a screenshot of ((As suggested by the mapmaker himself.)) to illustrate my point and pique Luigi further. But apparently there is no knowledge of climate change adaptation and mitigation happening anywhere CCAFS doesn’t work, which I’m sure is just a coincidence.

Sorghum and ethnicity in Africa

Ever since I contributed to A methodological model for ecogeographic surveys of crops, and suggested that collectors should do this, I’ve been waiting for the time when it would be easy — or even possible — to map the distribution of conserved germplasm on top of cultural, ethnic or language boundaries. The problem has been that maps of such boundaries, ((And yes, I’m aware that there are problems with mapping languages et al., but for the purposes of this, let’s just say I don’t care.)) though available in various printed formats, have not been much digitized. Or at least I hadn’t come across them. Until I happened on a blog post about the Center for Geographic Analysis’ (Harvard University) WorldMap, an open source web mapping system. The layers provided include one called Ethnicity Felix 2001, which “consist of polygons and labels depicting ethnicity information based on the ‘People’s Atlas of Africa’ by Marc Felix and Charles Meur, Copyright 2001.” Perfect, I thought.

Sorghum accessions (Genesys) and ethnic groups in Uganda.
Well, not so fast. It was not altogether easy to download a shapefile of conserved African sorghum landraces from Genesys that would upload into WorldMap, plonk it on top of Ethnicity Felix 2001 and produce a shareable map. Not easy, but possible. It took some time and some divine intervention from Robert, but I do now have a map of African ethnic groups and sorghum collections that other people can have a look at. At left you have a snippet showing Uganda to whet your appetite. So now, in addition to things like ecogeographic gaps in collections, made possible by global climate surfaces, we can also begin to investigate cultural gaps.

Nibbles: Collecting, US heirlooms, Sequencing NUS, Nutrition strategies, Potatoes and climate change, Italian genetics

  • 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.
