Unlocking a presentation on unlocking agriculture’s past

The talk that Jacob is planning to give later today at the National Geographic store in Madrid (and you can follow online) is now available on Slideshare.

Unlocking Agriculture's Past

LATER: I forgot to use a hashtag, but you can see my live-tweeting of Jacob’s talk by searching for his name. Maybe Jacob can tell us if the video will be available in due course. And no, he didn’t answer my online question about the difference between oca and potato. Wimp.

Nibbles: Food Deserts, Garlics, Communication, Bee breeding, Millets, Sweet potatoes, Visualizing herbaria, Medieval beer

The Economist discovers food deserts. Money quote: “some Americans simply do not care to eat a balanced diet, while others, increasingly, cannot afford to”.
William Woys Weaver on garlics, and America, and garlic in America.
Agricultural Communication for Development conference. Sure. But 12 days long?
Breeding a better bee. And why not?
Kenya Agricultural research Institute to release three new high-yielding finger millets.
Too many sweet potato seedlings. What’s a poor breeder to do?
A visual history of California botanizing.
Ah, to have lived at a time when a man got most of his calories from beer! No, wait…

Brainfood: Tomato erosion, Cassava starch, Landscape diversity, American chestnut, Niche models, Dormancy genes, Herbarium collections, Indian livestock breeding, Banana breeding, Pollinators, Shattering gene, Participatory research

The risks of success in quality vegetable markets: Possible genetic erosion in Marmande tomatoes (Solanum lycopersicum L.) and consumer dissatisfaction. Market takes the fun out of landraces.
Genetic variability of root peel thickness and its influence in extractable starch from cassava (Manihot esculenta Crantz) roots. Starch content depends on dry matter content and peel thickness. About 1500 accessions from CIAT evaluated for the latter, so lots to play around with.
A meta-analysis of crop pest and natural enemy response to landscape complexity. More landscape complexity means more natural enemies. Still no cure for cancer.
American Chestnut past and future: Implications of restoration for resource pulses and consumer populations of eastern U.S. forests. Reintroduction of blight-resistant chestnut may have some weird effects on other species.
Keep collecting: accurate species distribution modelling requires more collections than previously thought. Oh damn.
Variation in seed dormancy quantitative trait loci in Arabidopsis thaliana originating from one site. Is due to two QTLs. Also flowering time. But no, I don’t understand that “In contrast…” at the end of the abstract either.
Tracking origins of invasive herbivores through herbaria and archival DNA: the case of the horse-chestnut leaf miner. Another use for old herbarium specimens: finding evidence of pests.
Animal breeding in India – a time for reflection, and action. The reflection is that genetic improvement has stagnated, so the action needed includes better phenotypic record keeping, more attention to local diversity and community-breeding programmes.
Performance of micropropagation-induced off-type of East African highland banana (Musa AAA – East Africa). A promising avenue for improvement, the off-types yield more better bananas, a month later.
Pollination services in the UK: How important are honeybees? Not as important as you might think!
The same regulatory point mutation changed seed-dispersal structures in evolution and domestication. Cabbage-family fruit development and rice shattering share the same single point mutation.
Participatory research and on-farm management of agricultural biodiversity in Europe. By Michel “Pimpert”. That should be Pimbert. Old news, but worth mentioning.

Nibbles: FAO, Spirituality, ASARECA, Land use, Conservation agriculture, REDD, Colombian beans, Immigrant cooking, Exploding watermelons, AnGR

Calestous Juma gives new FAO head some advice: find a role, build on what farmers do and know, engage civil society, help governments prioritize, and slash bureaucracy.
Religion and conservation: friends of enemies?
Eastern Africa Agricultural Productivity Project seems to be mainly about setting up regional centres of excellence in dairy, cassava, rice and wheat. Maybe ASARECA should ask for some advice from Prof. Juma?
Land use map of the UK. Let the mash-upping begin.
Training in sustainable conservation agriculture in India and Mexico. But how really sustainable is the whole thing if based on modern varieties? Oh, and Brazil too.
Saving the Amazon for $33 a month.Or maybe just a buck?
Local cooking a long way from home, Part I; from Colombia to Washington DC.
Local cooking a long way from home, Part II; from everywhere to New York’s Lower East Side.
Don’t worry, exploding watermelons are perfectly safe, and legal.
FAO updates its webpage on “Implementing the Global Plan of Action for Animal Genetic Resources” and documents the fact by providing a time stamp. Jeremy chuffed.

Nibbles: Beautiful models, Beautiful bank, Organic FAO, Eskimo diet, Indian medicinals, Maya nut studentship, Fishy infographics

Official confirmation of the need for better crop growth models.
More on CIP’s high-tech spud bank. In other news, CIP also has banks of other Andean roots/tubers, but don’t get me started on that one.
“FAO has relegated organic agriculture to a footnote in the discussion of food security in the long run.” Fighting talk. Wonder if that will change with the new DG.
Cook like an Inuit.
Cultivating medicinal plants in India. Let’s see how that goes.
Wanna study the Maya nut?
More great Guardian infographics, aquatic edition.
“This one tastes like cotton candy.” Breeding strawberries the hard way.
