- A toolkit to help indigenous communities do conservation. Should they need one.
- On the other hand… Half of Japan’s endangered species hotspots are found in satoyama, which are under pressure. Compare and contrast with rice farming in Thailand.
- Learn all about some medicinal plants of the Amazon, minus their scientific names. Not including runa tea. Lots of other opportunities out there, though.
- Maybe even including oysters.
- Jeremy no doubt to feast on the mollusc after spilling the beans on the EU seed regulations at the Seed Savers jamboree.
- Wonder what Calestous Juma thinks of those regulations.
- But I bet he (and his father, who introduced the crop to his region of Kenya) would like this cassava website to rule them all.
- The Volcani Institute‘s gifts to the world…
- …probably include new strawberries, but not this one.
- Scientists straining, failing to find plant to meaningfully compare to the giant panda.
- Bioversity does up its iButtons.
- And gets a namecheck in a paean to the FAO Commission on GRFA on its 30th birthday. All this FAO stuff is because its Conference is on this week. I don’t suppose any of it will be more important than Amartya Sen’s speech.
Nibbles: Tree domestication, Sacred groves, Solomons aquaculture, Bees and diversity
- Cultivate medicinal trees to save them. Oh, and provide medicines.
- Or you could harvest them sustainably from sacred forests?
- Reef fished out? Aquaculture to the rescue. Sounds a bit like the aquatic equivalent of the above, no? But do they have sea cucumbers and their poop in those inland ponds?
- Growing diverse crops good for bees, good for crops. Buckwheat diverse enough for ya?
Nibbles: Bamboo shoots, Cassava bread, Tomato reefer, Visionary scientists, Price volatility, Potato nutrition, Climate change & biodiversity
- After artichokes and asparagus, bamboo, obviously.
- And after bamboo? Cassava, by any of its many names.
- Botanical confusion: “Good tomatoes are a lot harder to get than good pot.” Not where I come from.
- The Union of Concerned Scientists is concerned about US agriculture.
- Per Pinstrup-Andersen is concerned about food price volatility, not high food prices.
- And Jeremy is concerned that he may not be eating enough potatoes.
- Luigi, for his part, is concerned about the two thirds of common plants that CIAT et al. say could lose 50% of their range by 2080.
Conserving Prunus africana?
I’ve been sitting on it for a while, but a paper which AoB Blog discussed back in January led me to uncover a whole load of stuff on Prunus africana. The African Cherry Tree does not rate a leaflet in the African Food Tree Species series, perhaps because it’s not a, well, food tree, but that doesn’t mean it’s not important.
Chemicals extracted from the tree’s bark are used in a range of pharmaceutical products to treat enlarged prostate (benign prostatic hyperplasia), an extremely common condition that affects up to half of men aged over 50.
Hence various efforts to develop sustainable harvesting methods. And also an interesting series of diversity and demographic studies:
- Phylogeography of the Afromontane Prunus africana reveals a former migration corridor between East and West African highlands: “The high genetic similarity found between western Uganda and west African populations indicates that a former Afromontane migration corridor may have existed through Equatorial Africa.”
- Structural diversity and regeneration of the endangered Prunus africana (Rosaceae) in Zimbabwe: “…poor regeneration, fewer P. africana trees in small and large size classes, dominance of positive height and diameter differentiation and high mingling.”
- Divergent pattern of nuclear genetic diversity across the range of the Afromontane Prunus africana mirrors variable climate of African highlands: “The observed patterns indicate divergent population history across the continent most likely associated to Pleistocene changes in climatic conditions. The high genetic similarity between populations of West Africa with population of East Africa west of the Eastern Rift Valley … provides further evidence for a historical migration route. Contrasting estimates of recent and historical gene flow indicate a shift of the main barrier to gene flow from the Lake Victoria basin to the Eastern Rift Valley…”
- Modelling the potential distribution of endangered Prunus africana (Hook.f.) Kalkm. in East Africa: “Prunus africana distribution is thus highly vulnerable to a warming climate and highlights the fact that both in-situ and ex-situ conservation will be a solution to global warming.”
Maybe we could do with some more seed behaviour data. But it would seem there is now plenty of diversity, demographic and sustainable harvesting information on which to base a comprehensive conservation strategy. Is someone coming up with one?
Nibbles: GMO promises promises, African livestock outside & in, Vegetables galore, Farmer videos from US & Sri Lanka, Fermentation beery & otherwise, Yam people & traits, Botanic garden diversity, ECPGR, CWR in US & Benin, Herbarium data, Baobab info, Olean info, Pix, Indian cooking
- Nature “celebrates” 30 years of GMOs.
- African pastoralists know how not to destroy their livelihoods shock.
- African urban dwellers keep livestock shock.
- Vegetables can be perennial too. Oh yes indeedy. Not bitter gourd though, alas. Nor cucumber. And in other news, there’s a Bitter Melon Council. And also a campaign to promote zucchini in Iowa.
- Climate change reaches farmers in the Pacific NW. Can their Sri Lankan colleagues be far behind?
- Always good to have a beer story. Well, maybe not.
- Speaking of fermentation, this WSJ piece looks interesting, from the two sentences of it I can read. No, wait. Oh crap, try this.
- A hummus dip goes really nicely with beer. Is this the quinoa story again?
- A yam conference for the ages. Will they discuss the new trait ontology?
- Botanic gardens reach out. Genebanks next? Maybe not.
- You mean like the European ones, perhaps?
- That US CWR paper from the horse’s mouth. And a similar thing from Benin. But where does all that data come from?
- Baobab notes to go with all those factsheets.
- The Saharan olive needs a factsheet too. IRD obliges.
- Cool set of agriculture photos.
- A couple of different views of Indian food. Thanks to Cara de Silva and Diana Buja.
