- There’s a celebration of the thinking of Robert Chambers over at IDS Bulletin. He’s been advocating for participation in development and the importance of Indigenous knowledge, among other things, for 50 years.
- The Center on Global Food and Agriculture has a report out called “Defining the Path to Zero Hunger in an Equitable World” which basically tries to add humanitarian assistance to the old food-climate-biodiversity nexus. Crop diversity is nowhere to be found among the “catalyzing ideas,” but one of those is investing in “force multipliers,” and that includes agricultural research and development. Participatory agricultural research and development, presumably?
- Meanwhile, China has collected 124,000 crop diversity samples.
- And a Spanish microbiologist has collected 3,600 bacteria.
- The PNAS Special feature: Harnessing crop diversity, organized by Susan McCouch, Loren Rieseberg and Pamela Ronald, got a nice write-up in the latest Plant Science Research Weekly. But what would Robert Chambers say? Anyway, should I do a special Brainfood on it? Let me know in the comments, as the cool kids say.
Nibbles: Wild tomatoes, Ghana genebank, India livestock census, USDA coffee breeding, Native Americans & their horses
- It’s pretty rare to have a mainstream media piece on the use of crop wild relatives for climate change adaptation but here we have an example with tomato, so make the most of it. There’s an interesting wrinkle though, so more to come, time permitting.
- It’s even rarer to see a mainstream media piece on genebank staff getting trained. What’s going on out there?
- Not exactly mainstream media, but how many times have you seen an official government press release on its livestock censuses? Anyway, India’s last one was carried out in 2019 and covered 184 breeds of 16 species. Wonder where the data is.
- Speaking of government press releases, here’s one from USDA announcing that it has joined a coffee breeding network. Well, I for one think it’s important.
- And staying in the USA, you know how you read in mainstream textbooks that Native Americans got horses from retreating Spanish colonists after the Pueblo Revolt? And you know how Native Americans have been saying that’s not what they think happened? How rare is it that a scientific paper involving Indigenous authors overturns a mainstream historical narrative and is splashed all over the mainstream media? Very rare, that’s how rare.
Nibbles: Food tree, Wild chocolate, Cacao, Cassava in Africa, Indigenous ABS, Abbasid food, Valuing trees
- Gastropod episode on The Fruit that Could Save the World. Any guesses what that might be?
- Atlas Obscura podcast on an apparently now famous wild-harvested chocolate from Bolivia. But how wild is it really?
- BBC podcast on cacao for balance.
- Forbes touts an African cassava revolution. What, no podcast?
- Very interesting piece from the ever reliable Modern Farmer on how a small seed company called Fedco Seeds designated a bunch of maize landraces as “indigenously stewarded,” and are paying 10% of what they make from the sale of their seeds to a pooled Indigenous fund which goes to support a local, multi-tribal project called Nibezun. A sort of mini-MLS? Definitely worth a podcast. Any takers?
- A long but rewarding article in New Lines Magazine describes medieval cookbooks from the Abbasid caliphate. The recipes make up for the somewhat stilted podcast.
- BGCI publication on how the Morton Arboretum works out whether it should be growing a particular population or species of tree. The trick is to quantify 5 types of “value”: environmental, evolutionary, genetic diversity, horticultural, conservation. Though one could also consider hostorical/cultural, educational and economic value as well. I suspect in the end it comes down to whether it looks nice in an available gap. If I were to do a podcast on this, I’d test it out with the tree in the first of these Nibbles.
What will AI ever do for us?
Ever since ChatGPT hit the internet a few weeks ago AI has been all over what we are now obliged to call the discourse, so I figured I’d wade in. Jumping in right at the deep end, I asked it the following: Which barley genebank accessions are the most drought tolerant? Here’s what I got.
Determining the most drought-tolerant barley genebank accessions would require a comprehensive analysis of multiple factors, such as yield performance, physiological traits, genetic diversity, and environmental adaptation. However, there are some barley genebank accessions that have been reported to exhibit high levels of drought tolerance based on various studies and evaluations. Here are a few examples:
- CI 9835: This barley accession from Ethiopia has shown high levels of drought tolerance in several studies. It has been found to maintain high yields and exhibit drought avoidance traits such as early maturity and reduced plant height.
- Himalaya 10: This Indian barley accession has demonstrated good drought tolerance and yield stability in multiple environments. It has also been found to possess traits such as deep rooting, reduced stomatal conductance, and high water use efficiency.
- Hordeum vulgare L. subsp. spontaneum: This wild barley subspecies from Israel has been found to possess high levels of genetic diversity and adaptability to harsh environments, including drought-prone areas. It has also been shown to possess traits such as deep roots, reduced leaf area, and efficient water uptake.
These are just a few examples, and there are likely many other barley genebank accessions that exhibit high levels of drought tolerance. The specific characteristics that contribute to drought tolerance can vary depending on the accession and the environment, so it is important to evaluate multiple traits and consider multiple environments when assessing drought tolerance in barley genebank accessions.
I mean, that’s not too bad I guess, as far as it goes. CI 9835 is a bona fide genebank accession, and it is from Ethiopia. But I can’t locate a study which highlighted it as being particularly drought tolerant. Himalaya 10 is an elite hulless barley, not a genebank accessions, and from Tibet rather than India, but it does seem to be drought tolerant. As for wild barley, some accessions do have potential.
I then tried Consensus, which is a sort of AI-driven Google Scholar type thing. Like Scholar, it returned a bunch of papers evaluating different barleys for drought tolerance, which one could obviously scour for specific accessions. But, intriguingly, it also provides a sort of summary of what it found:
These studies suggest that STI, GMP, MP indices, two wild Iranian genotypes, and early seedling stage accessions are the most drought-tolerant barley genebank accessions.
Which unfortunately is not much use, let’s be honest. For now. It’s in beta, so it will no doubt get better.
So someone tackling the problem from scratch has a place to start, but clearly what we need next is a way to apply AI directly to genebank databases. Or even for AI to understand a bit better what a genebank accessions is.
Going with the genebank workflows
I suspect everyone working in genebanks and other sorts of biorepositories will welcome the new book “Biodiversity Biobanking – a Handbook on Protocols and Practices” by Carolina Corrales and Jonas Astrin.
We compiled extensive information on … workflows from throughout most of the biodiversity and environmental biobanking communities. Publications, grey literature, and Internet sources were reviewed, and proven experts consulted. By linking to protocols and practices from many different types of biobanks we hope to inspire interdisciplinary approaches and interconnect biobankers, and to serve as an aggregated resource for incipient and thematically expanding biobanks. Maybe the compilation of practices can also contribute to processes of method validation and standardisation.
Here’s hoping…
