- Food systems: seven priorities to end hunger and protect the planet. Oh good, includes “Biodiversity and genetic bases need to be protected. Seed varieties must be preserved, and their phenotypes and genotypes explored in the contexts of climate change and nutrition. Traditional food and forest systems, including those of Indigenous peoples, need to be better understood and supported in national agricultural research systems.” Phew.
- Future Changes in Wet and Dry Season Characteristics in CMIP5 and CMIP6 Simulations. The above is just as well because longer hotter and drier spells are coming to the tropics, and crops will suffer.
- Global assessment of the impacts of COVID-19 on food security. Plus there’s this too. Resilience has a cost.
- The future of farming: Who will produce our food? Smallholders…
- When agriculture drives development: Lessons from the Green Revolution. …and that may be bad.
- Ok, the above two entries need unpacking. The second paper shows that the “agricultural engine of growth” was totally a thing during the Green Revolution, but the first that it now appears to be broken.
- Extinction risk of Mesoamerican crop wild relatives. Oh no, on top of everything else, we might lose avocados and vanilla.
- Determinants of Smallholder Maintenance of Crop Diversity in Morocco’s High Atlas Mountains. Markets, land and water. So what would any new Green Revolution do to diversity? Have we learned anything?
- Landscape complexity and US crop production. …are positively correlated. For Morocco too, I wonder?
- Utilize existing genetic diversity before genetic modification in indigenous crops. At least in Ethiopia.
- Compulsion and reactance: Why do some green consumers fail to follow through with planned environmental behaviors? Because some believe in technology, and other is abstinence. Which means they need different messages to encourage them to put their money where their mouths are. Would it work in Ethiopia?
Featured: Breeding with wild peanuts
David Bertioli points out, in a comment to a blog post about a recent paper of his, that there’s more than one way to use peanut wild relatives in breeding:
Your previous blog detailed the impact of Charles Simpson’s crosses in Texas, which used the “tetraploid route” of introgression which donated a chromosome segment from A09 which confers root knot nematode resistance. The PNAS paper focuses mostly on progeny from the North Carolina “hexaploid route”, which ended up traveling most around the world. These introgressions, from A02 and A03, confer resistance to Late Leaf Spot, Rust, and to a lesser extent Web Blotch.
Would be interesting to compare the impacts of the two “routes.”
Feeling even better about crop wild relatives
The publication of “Legacy genetics of Arachis cardenasii in the peanut crop shows the profound benefits of international seed exchange” in PNAS rang a faint bell:
Here, we uncover the contribution of one wild species accession, Arachis cardenasii GKP 10017, to the peanut crop (Arachis hypogaea) that was initiated by complex hybridizations in the 1960s and propagated by international seed exchange.
And yes, it turns out we had blogged about this wild peanut species more than a decade ago, in Another feel-good crop wild relative story.
Some things have changed since 2008, I’m happy to say. I seem to have had some difficulty pulling together data ((And the links are now dead.)) at the time, whereas Genesys had no trouble at all showing me 45 accessions. And GKP 10017 even has a DOI now.
Brainfood: Mapping double, Niche modelling, CGIAR impacts, Pathogen genebank, Data stewardship, Breeding tradeoffs, Organic vs conventional, Agronomic trials, Teff evaluation, Eggplant genetic resources, Quinoa phenotyping
- Conservation needs to break free from global priority mapping. Couldn’t agree more. And less.
- National climate and biodiversity strategies are hamstrung by a lack of maps. Wait, what?
- The evolutionary genomics of species’ responses to climate change. You need to combine niche modelling with genetic adaptation to get the best maps.
- Payoffs to a half century of CGIAR research. A benefit-to-cost ratio (BCR) of 10:1. Not counting the genebanks. And all the maps.
- A case for conserving plant pathogens. But will it be worth it?
- Poor data stewardship will hinder global genetic diversity surveillance. What’s the BCR for decent metadata?
- Mitigating tradeoffs in plant breeding. Cutting out the cross-talk changes tradeoff to payoff.
- Comparing Productivity of Organic and Conventional Farming Systems: A Quantitative Review. Conventional is more productive. But should yield be the only criterion?
- Priority micronutrient density in foods. Right. Micronutrients are also important.
- Reconciling yield gains in agronomic trials with returns under African smallholder conditions. And how was yield measured anyway?
- Data-driven, participatory characterization of traditional farmer varieties discloses teff (Eragrostis tef) adaptive and breeding potential under current and future climates. This might well be an example of applying the lessons of the above.
- Genetic Diversity and Utilization of Cultivated Eggplant Germplasm in Varietal Improvement. The wild relatives will save us.
- Quinoa Phenotyping Methodologies: An International Consensus. But will it work for the wild relatives? Just kidding, this is an important development for another crop (with the above) which doesn’t have something like the CGIAR and its 10:1 BCR behind it…
Nibbles: Luxury brands, Food companies, TV and diets, Saving seeds, IUCN Green Status, 0 Hunger Pledge, Zizania
- Luxury brands discover biodiversity: “There is no champagne without grapes, no ready-to-wear without silk and cotton, no perfume without flowers…”
- What about global food and agriculture companies though? Let’s find out, shall we?
- TV can help where companies won’t.
- Of course, you can set up your own company, as these Tunisian women did.
- Imagine a company helping to move a species to “green status.” Imagine.
- They could sign the Zero Hunger Pledge for the Private Sector while they’re at it.
- But meanwhile, on Ojibwe land…
