Mapping potato genetic resources
And speaking of genetic erosion:
Land use tendencies between 1997 and 2005 shows that the total cropping area dedicated to improved cultivars has grown fast while the area reserved for native-floury and native-bitter landrace has remained more or less stable. Reduced fallow periods for existing fields and the gradual incorporating of high-altitude virgin pasture lands sustain areal growth. While areas of improved cultivars are proportionally growing fastest at extremely high altitudes between 3,900 and 4,350 m of altitude, overall cropping intensity or fallowing rates are inversely related to altitude. No evidence of a straightforward replacement of one cultivar category by another was found.
That’s from the winners of the third prize at the SCGIS/ESRI/SCB International Conservation Mapping Contest, Traditional Cartography section: CIP’s Henry Saul Juarez Soto, with Franklin Plasencia and Stef de Haan. Worth reading the whole thing.
Nibbles: European diversity, Cassava bugs, Livestock funding, Malnutrition
- Genetic diversity in European men and one of the organisms they exploit. And another.
- CIAT cassava entomologist rings warning bell.
- ILRI boffins point out why they don’t have enough money. Yeah, but what’s to be done about it?
- Malnutrition in Kenya and Guatemala. Are school gardens an/the answer? FAO thinks so.
A tale of genetic erosion narrowly averted
What causes genetic erosion? People in our business are way too fond of making lists of all the things that can possibly lead to a farmer abandoning a variety. But sometimes it’s just down to an accident. Take my mother-in-law. Please. No, but seriously, this is an interesting example of the law of unintended consequences. Bear with me. The mother-in-law grows some hybrid maize on her spread in the Limuru highlands of Kenya. Here she is with a bag of the stuff, which she likes, despite the recurrent cost, because of the large cobs.
But she also grows a local landrace which she says goes back to before independence. It doesn’t yield as much, but it has thick juicy stems, and she needs that for her cows. So she grows both the hybrid and the landrace, not mixed up in the same field, but often side by side. Would be interesting to look at the geneflow that’s been happening up there over the years, but that’s not the point of this story.
The point of the story is in fact that she almost lost the landrace recently. What happened is that last year she came to visit us in Rome for a few months, and left the farm in the otherwise quite capable hands of her daughter-in-law. Problem is, Violet, unaware of the preciousness of the landrace seed, went and fed most of it to the family. Fortunately, a handful or so survived, and quickly went into the ground for multiplication when grandma returned. You can see it here above. A close-run thing indeed. She says she would have been very upset if she had lost that seed, and asked me whether I could get it into Svalbard. After all, is that not my boss holding some seeds in front of the Vault? Well, yes, but…
