- Pretty much the last thing biofortified crops do is empower farmers to be food system change agents. But they’re still a pretty good idea.
- Same for the sweet potato in the Caribbean. On both counts.
- Jeremy’s latest on saving rare livestock breeds. Now, that would change the food system a bit.
- But would those rare breeds work on Zoom?
- Maybe this farmers market in Nairobi could stir things up a bit.
- Learning from Native American farming practices is always a good idea.
- Rethinking the Amazon development model could do with some of that too.
- Grapevine wild relatives are pretty empowering too.
- And, for at least one chef, so is eelgrass.
Brainfood: Livestock edition
- Recent land use and management changes decouple the adaptation of livestock diversity to the environment. The diversity of traditional livestock breeds used to be closely related to climate in Spain, but this is breaking down.
- Rationalizing ex situ collection of reproductive materials for endangered livestock breed conservation. Also in Spain, so I hope these guys are talking to the above.
- Applying the zoo model to conservation of threatened exceptional plant species. Not to mention livestock in Spain? Basically talking about a pedigree-based approach.
- Selection and drift reduce genetic variation for milk yield in Manech Tête Rousse dairy sheep. A bit like this (see above)?
- Influence of land tenure interventions on human well-being and environmental outcomes. Fairly good evidence from meta-review that formal titling has good social and environmental outcomes. But what did it do for traditional breeds, right?
- Lipid residues in pottery from the Indus Civilisation in northwest India. Not as much dairy as thought, and mainly non-ruminant fats. Definitely traditional breeds though.
- Ancient proteins provide evidence of dairy consumption in eastern Africa. Starting when lactase persistence was still rare or absent.
- Genome-scale sequencing and analysis of human, wolf and bison DNA from 25,000 year-old sediment. Sediment? Yep, sediment.
- Effect of dry heat on seed germination of Desmodium and Stylosanthes species. Could be used rather than mechanical scarification, thus saving time and effort. Livestock gotta eat.
Nibbles: Duck breeding, Native American seeds, Climate change & wildlife
- A better Peking duck.
- Cherokee Nation makes heirloom seeds available.
- “Every degree of warming avoided prevents the loss of one in ten species from the world’s tropical and Mediterranean climates.”
Nibbles: GMO, EUGENA, Geography, Ozark food, UK seeds
- There’s more to the whole GMO thing than science.
- The European Genebank Network for Animal Genetic Resources has cool new flyers.
- Geographies of Food: The Book.
- The above applied to the Ozarks and the UK.

- Tropical forage technologies can deliver multiple benefits in Sub-Saharan Africa. A meta-analysis. Including improved germplasm, which had on average 2.6 times higher herbage productivity than local controls.
- Effective population size remains a suitable, pragmatic indicator of genetic diversity for all species, including forest trees. Which is good because you can estimate it fairly easily. Well, kinda. It’s important because it’s one of the Genetic diversity targets and indicators proposed for the CBD post-2020 Global Biodiversity Framework.
- Exploring the genetic variability and diversity of pearl millet core collection germplasm for grain nutritional traits improvement. 15 of 212 accessions are good for multiple nutrients.
- Global Status of Sorghum Genetic Resources Conservation. The two biggest collections are updating their data.
- Genomic basis of geographical adaptation to soil nitrogen in rice. Rice lost high tillering in high N conditions, but can get it back to cope with low N conditions.
- The Economic Impact of Exchanging Breeding Material: Assessing Winter Wheat Production in Germany. It really pays for breeders to exchange material.
- Comparative analysis of the gene pool structure of Triticum aethiopicum wheat accessions conserved ex situ and recollected in fields after 85 years. Vavilov’s collections are more diverse.
- Evidence for Two Main Domestication Trajectories in Saccharomyces cerevisiae Linked to Distinct Bread-Making Processes. Being adapted for industrial and artisanal baking respectively.
- Entrelaçado, a rare maize race conserved in Southwestern Amazonia. Gap-filling pays off. Hope we can re-collect it in 85 years’ time.
- ValSten: a new wild species derived allotetraploid for increasing genetic diversity of the peanut crop (Arachis hypogaea L.). Playing God with peanuts.
- Long-distance dispersal of the beach strawberry, Fragaria chiloensis, from North America to Chile and Hawaii. For the birds.
- Genetic architecture of wild soybean (Glycine soja Sieb. and Zucc.) populations originating from different East Asian regions. At least 3 separate groups, and the collection stored in Korea is pretty representative.
- Supporting habitat conservation with automated change detection in Google Earth Engine. Fancy math can detect land use change quickly and accurately.
- Health Impacts of the Green Revolution: Evidence from 600,000 births across the Developing World. Modern varieties reduced infant mortality by 2.4–5.3 percentage points (from 18%), with stronger effects for male infants and among poor households. Why we do all of the above?
- Articulating the effect of food systems innovation on the Sustainable Development Goals. Yeah, not so fast…
