The World Urban Forum is taking place down in my home town this week. That I suppose was what provided at least part of the impetus for the United Nations Standing Committee on Nutrition (UNSCN) to issue a statement on the Nutrition Security of Urban Populations. Not to be outdone, FAO has a publication out too, Growing Greener Cities in Africa, touted as the “first status report on urban and peri-urban horticulture in Africa.” A cursory glance doesn’t reveal much on diversity in these documents, but this is an issue that’s always intrigued me. Could cities act as magnets for crop inter- and intraspecific diversity? After all, they have lots of micro-niches, and have been attracting people from all over for decades, who could have come with their seeds. Is it possible that varieties could still be grown in cities after they’ve disappeared in their native areas? Or at any rate that crop diversity in a city is higher than in the surrounding countryside? Sometime ago we did a small survey of sweet potato diversity in Nairobi roadside verges that seemed to suggest that the menu of varieties was at least somewhat different from what was available in nearby rural areas. Should write that up one day. Anybody know of similar studies?
What I read on my summer holidays
Yeah, summer is over and I’m back at work. Maybe you noticed I haven’t contributed much here in the past month or so. Or maybe you didn’t. Jeremy kept up a steady stream of agrobiodiversity nuggets pretty much all through August. But my lack of activity on the blog doesn’t mean I haven’t tried to keep up, as you would know if you followed us on Facebook, Twitter or Scoop.it. Anyway, for those that don’t, and would like to catch up on my summer reading, here is, in nibble form, what caught my eye during the past month or so:
- “The potato is a religious commodity in America.” Explaining the governance crisis in the US using the humble spud.
- Wait a minute though: “The sizzle seems to be gone from America’s long-term relationship with the potato.” Which apparently means it needs an extreme makeover, colour-wise. For which you’ll need a genebank.
- A tree’s leaves can be genetically different from its roots. Does that mean we have to re-think all molecular phylogenies?
- And speaking of a tree’s leaves, these ones are a thousand years old and give you a buzz.
- A toff with a passion for pigs. P.G. Wodehouse had something to say about this, didn’t he?
- Turns out WFP has a podcast. And ICIMOD has an RSS feed.
- A mathematician factchecks Michael Pollan.
- Pear with me please, while I tell you about another USDA fruit collection.
- 15 Africa-changing innovations include orange-fleshed sweet potatoes. As if they weren’t there before. Anyway, they were THE story for a couple of weeks in August.
- 12 food security innovations include increasing crop diversity. With orange-fleshed sweet potatoes?
- How to put that banana genome to some use.
- Getting the most out of your enumerators.
- IUCN’s Conservation Campus. Any ag? And on a similar topic, training materials in anthropology.
- Automating conservation assessment of plants. You’ll need provenance data from herbaria such as this one at CIP, of course. Oh, and speaking of CIP, they need a phylogeneticist.
- A market opportunity for the mother-in-law?
- Measuring the health of the oceans. Hey, but it’s not all bad for fish.
- Ten species which rely on ex situ conservation. And why that number will go up. How to pay for it all, though?
- Book on the recent history of agricultural research reviewed. I wonder if they looked at the private sector. Because it seems there may be a case to answer.
- Another big grant for taxonomic databases. Ah but this is all going to be community-driven.
- Looks like this Australian genebank could have done with a decent database, community-driven or not.
Brainfood: Lathyrus sativus, Leafy green porridge, iDArTs, Pungency, Earth ovens, Domestication, Recovery, Maize genomics
- Exploring the genetic diversity of Ethiopian grass pea (Lathyrus sativus L.) using EST-SSR markers. They’re variable, especially in Gonder, and future collecting missions need to give “due attention to underrepresented regions”.
- Green leafy porridges: how good are they in controlling glycaemic response?. Pretty good, but the leafy greens may not be what you’re expecting.
- iDArTs: increasing the value of genomic resources at no cost. No cost for genotyping, that is; the analysis probably does cost.
- A versatile PCR marker for pungency in Capsicum spp. Beats having to taste each progeny plant, I suppose.
- Earth Ovens (Píib) in the Maya Lowlands: Ethnobotanical Data Supporting Early Use. The food preparation method is as old as the food itself; 3400-3000 bce.
- Patterns and processes in crop domestication: an historical review and quantitative analysis of 203 global food crops. Terrific, broad survey, worth more of a write-up.
- Changes in Avian and Plant Communities of Aspen Woodlands over 12 Years after Livestock Removal in the Northwestern Great Basin. Removing livestock leads to “recovery of biological integrity”. Because livestock are not integral to anything.
- Historical genomics of North American maize. Fascinating analysis indicates selection based on a limited set of ancestor lines, and “decreased diversity in the ancestry of individual lines”.
Mexican maize biodiversity documented
Via El Cuexcomate, news that CONABIO now has information on the maize races of Mexico on its website, including photos and distribution maps. It’s all part of a huge project to document native maize diversity (including the wild relatives) which was stimulated by fears ((So whether justified or not, at least it cannot be denied that these fears had one positive outcome.)) about the influx of GM maize. And since we’re on the subject of maize, today also saw an informative post on pellagra, complete with very dramatic illustrations.
Sudanese sorghum by the numbers
The Plant Genetic Resources Unit of the Agricultural Research Corporation (ARC) of Sudan has just published a catalog of its sorghum collection. It mainly contains reams of characterization data, which of course will be easier to explore in their digital form, but it’s always good to have illustrations to go with the numbers. Would be great to see the data eventually make their way to Genesys.
