- Livestock grazing boosts plant diversity in the Greater Serengeti–Mara Ecosystem. Livestock can be good for biodiversity conservation. But can its diversity be conserved too? Let’s see.
- Conservation and Management of Animal Genetic Resources in the Context of African Livestock Production Systems: The Case for In Situ and Ex Situ Conservation. “The multi-stakeholder breeders-researchers-decision-makers approach remains the most robust solution for sound management and preservation of biological units.” What, no farmers and local communities? No, that’s unfair: community-based conservation is discussed. But it doesn’t feel as central to the whole thing as it should be, somehow.
- Genetic Diversity, Adaptation, Wild Introgression, and Coat Color Mutation of Golden Yak. After all, local communities have maintained the golden yak reasonably well.
- Caprine dairy exploitation on the Iranian Plateau from the seventh millennium BC. Not to mention goats in Iran, and for thousands of years…
- Old goats: 3,000 years of genetic connectivity of the domestic goat in Ireland. …and in Ireland, though for not quite as long, admittedly.
- Dogs were widely distributed across western Eurasia during the Palaeolithic. And local communities have been managing dog populations since way before farming even.
- The dispersal of domestic cats from North Africa to Europe around 2000 years ago. Also, local communities managed early cats separately in the Levant and Egypt. Much later than dogs, but that’s cats for you.
- A microbiome catalog of Chinese traditional artisanal cheeses provides insights into functional and microbial diversity. And don’t forget to conserve the associated microbiome too. I wonder what golden yak cheese is like.
We need diverse farms, and genebanks can help
A LinkedIn post by CGIAR stalwart Dr Carlo Fadda convinced me I should give a bit more exposure to a recent paper than the brief Brainfood entry I wrote about it a few weeks ago. The paper is Long-term agricultural diversification increases financial profitability, biodiversity, and ecosystem services: a second-order meta-analysis. Its authors are Estelle Raveloaritiana and Thomas Cherico Wanger, and it was published in Nature Communications this past January.
In that Brainfood, I tried to bring together in a logical thread various studies on different aspects of farm diversity and its benefits. In particular, its effects on diet diversity, and hence health outcomes.
But better diets and human health are not the only pluses of diverse farms, and the paper in question in fact suggests that intercropping, organic farming, and other diversification strategies also increase incomes, biodiversity, pollination, soil quality, and carbon sequestration significantly over 20 years. With, importantly, no downward hit on crop yields. So going diverse — organic, if you will — has many advantages that are not overall associated with a yield tradeoff. And that’s from a meta-analysis of 184 meta-analyses and 120 years of data, so it’s a pretty robust result.
As Dr Fadda points out in his excellent summary of the paper, good evidence that diverse — including agrobiodiverse — farms are good for farmers, consumers and the planet is clearly there. The challenge is to find the institutional will to act on it.
I’d like to add that genebanks around the world are ready, willing and able to do just that. It’s literally their job, or at least a big part of it. I hope they are given the chance — and the resources — to do it.
Yes, win-win-win diets are possible
Happy to second the sentiment expressed in this snippet from Jeremy’s latest newsletter. And there are so very many more equally interesting snippets to be found across the previous 299 issues, going back almost exactly 11 years. Congrats, Jeremy!
I heartily applaud scientists who take the trouble to create a more accessible version of their research results, and not only because it saves me the effort. I’m very happy, then, to refer you to two versions from two of the authors of Strategies for achieving healthy, sustainable, and equitable dietary transitions, recently published in Science.
The paper “connects the behaviors of consumers, producers, and the midstream actors who influence both supply and demand. It then proposes solutions based on syntheses of evidence across major intervention domains”.
Jess Fanzo and Marc Bellemare — both no stranger to the podcast — have made it easier for the rest of us to understand the complexities and difficulties involved.

- Global impacts of increased undervalued crop production on environmental, economic, and nutrient outcomes. It’s even good for emissions. No regrets indeed. But who’s going to do drive all this diversification?
- Impact of a homegardening intervention on crop diversity: results from a cluster-randomized trial in Bangladesh. Homegardeners maybe?
- National genebanks as agents of change for supporting farmers’ crop diversification. Oh, I know who else can help.

JSTOR in a pickle with Jeremy
From Jeremy’s latest newsletter. To which of course you should subscribe. You’ll see he mentions Charles Darwin right up front, which allows me to link to a new course based on teaching materials created by Darwin’s Cambridge menor, Prof. John Stevens Henslow.
Plant of the Month from JSTOR is the cucumber. As usual for this series, there’s a ton of fascinating information and links, from the compilation of cats confronted by cucumbers to their inspiration of one of Charles Darwin’s lesser-known books.
Why, though, cool as a cucumber? In some sense it seems obvious that the cucumber is simply well-flavoured wateriness most available during summer’s heat. Could it, really, have prevented sweating? And while people swear by the beneficial effects of a good, thick slice on the eyes as a rejuvenator, reducer of puffiness, etc., etc., there doesn’t seem to be any good evidence that a cucumber is better than, say, a used tea bag or wet cotton wool. JSTOR doesn’t even mention the practice.
Allow me, please, a quibble. JSTOR’s caption for its first image … is “Two dill cucumbers. Watercolour painting by a Chinese artist”. Fair enough, that is how it is labelled at its source. But surely a cucumber on the vine cannot be a dill cucumber until it has been brined and fermented, with dill.
And if that’s not confusing enough, try a deep dive into cucurbit names, an episode from 2016.
