- 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.
