Imminent extinction of bananas … again
Science Friday, a series on the US National Public Radio, last week interviewed Dan Koeppel, author of Banana: The Fate of the Fruit That Changed the World. Koeppel recently fanned the embers of bananas-are-going-extinct back into a roaring blaze. That particular take on the new races of diseases that threaten the world’s favourite fruit started in a January 2003 article in New Scientist magazine (helpfully summarized by The Guardian) and of course one should always take the sub-editor’s art with a pinch of salt. FAO, not one to miss an opportunity, jumped on the extinction story too, which New Scientist duly covered.
So, extinct, probably not. But if it gets you to care about agricultural biodiversity, I’m all in favour of it.
You can listen to the story from NPR’s site (and read a transcript for good measure). I liked the interview, not because bananas in general are or are not going extinct, but because Koeppel explained so clearly the super-efficient business model that puts bananas on the supermarket shelves at scarily low prices. It is a business model that none of the incumbents is willing to abandon until absolutely necessary, and that makes the cost of entry for a new player, or a new variety, impossibly high.
I also liked Koeppel’s confidence in fingering just one variety — ibota ibota — as his absolute favourite. A quick search session revealed that ibota ibota is quite probably a synonym of Yangambi km5, a banana variety whose name is whispered reverently wherever banana enthusiasts gather. Or maybe it is more complicated than that. Banana stories usually are.

- Contribution of pollinator-mediated crops to nutrients in the human food supply. 90% of Vitamin C for a start.
- Foraging behavior of Alberes cattle in a Mediterranean forest ecosystem. It’s a semi-feral breed in NE Spain and its foraging behaviour may well decrease the risk of fires.
- Assessing the impact of the SASA/CASREN technology interventions in the sweet potato-pig production systems in Zitong County (Sichuan, China). All well and good but in this day and age one would expect some exploration of the sustainability of the interventions.
- Proposal for a Kava Quality Standardization Code. Very much needed because poor quality was probably responsible for examples of liver toxicity in the past. This is how to avoid that in the future.
- Clipping stimulates productivity but not diversity in improved and semi-natural pastures in temperate Japan. Semi-natural pastures are more diverse than improved pastures, and can be reasonably productive. So there.
- Pollen flows within and between rice and millet fields in relation to farmer variety development in The Gambia. Depends on breeding system. Likely higher within fields than between. Still no cure for cancer.
- Land, landlords and sustainable livelihoods: The impact of agrarian reform on a coconut hacienda in the Philippines. It seems to be mainly in the mind.
- Genetic divergence is not the same as phenotypic divergence. It isn’t? I’ll alert the media.
- Scope economies and technical efficiency of cocoa agroforesty systems in Ghana. Multi-crop cocoa farms are better, in multiple ways.
- Gene flow increases fitness at the warm edge of a species’ range. Outcrossing between edge populations better for living on the edge than outcrossing within edge populations, outcrossing with a center population or selfing. For a Californian annual anyway. Interesting consequences for in situ CWR conservation, in particular in context of re-introductions. Do we worry too much about “genetic pollution”?
