- Bending the curve of terrestrial biodiversity needs an integrated strategy. Meaning: (i) sustainable agricultural intensification, (ii) trade, (iii) less food waste, (iv) more plant-based human diets, and (v) more and better protected areas.
- The carbon opportunity cost of animal-sourced food production on land. See (iv) above.
- Just ten percent of the global terrestrial protected area network is structurally connected via intact land. See (v) above.
- Cropland expansion in the United States produces marginal yields at high costs to wildlife. See (i) above.
- A cultivated planet in 2010 – Part 1: The global synergy cropland map. Gotta know where the cropland is before you can do (i) above.
- Advances in plant phenomics: From data and algorithms to biological insights. Fancy maths can really help with (i) above.
- Retrospective Quantitative Genetic Analysis and Genomic Prediction of Global Wheat Yields. Different fancy maths shows that CIMMYT’s Obregon wheat testing site can really help with (i) above.
- Diversity analysis of 80,000 wheat accessions reveals consequences and opportunities of selection footprints. Here’s some stuff that wheat breeders can use to develop new materials to test at Obregon using phenomics, genomics and fancy maths.
- First report on cryopreservation of mature shoot tips of two avocado (Persea americana Mill.) rootstocks. This should help with (iv) above. Eventually, work with me here.
- Bread and porridge at Early Neolithic Göbekli Tepe: A new method to recognize products of cereal processing using quantitative functional analyses on grinding stones. Ahem. Well… No, sorry, I got nothing.

Brainfood: Special citizen science edition
Something for the weekend. I hope you enjoy this special edition of Brainfood focusing on citizen science, Indigenous knowledge and participatory research. Do you like themed Brainfood editions like this? There will be another one on Monday, as it happens. They’re more tricky to produce, but if there’s significant interest I may make the extra effort. Let me know, and suggest topics.
- The value of climate-resilient seeds for smallholder adaptation in sub-Saharan Africa. Up to USD 2 billion in Malawi and Tanzania over the next 30 years.
- Agricultural productivity and deforestation: Evidence from input subsidies and ethnic favoritism in Malawi. Cheaper fertilizers increased yields and decreased deforestation. Better seeds would help too, no doubt (see above).
- Channels used to deliver agricultural information and knowledge to smallholder farmers. Farmer groups and demonstration plots work well to spread the news about fertilizers and seeds.
- Integrating Conventional and Participatory Crop Improvement for Smallholder Agriculture Using the Seeds for Needs Approach: A Review. Combine high-tech centralized and participatory decentralized germplasm evaluation and breeding approaches to get those better seeds to farmer groups and their demonstration plots.
- Citizen science breathes new life into participatory agricultural research. A review. Why do the participatory, decentralized bit? Here’s why. Fortunately, there’s an app for it…
- A global resource for exploring and exploiting genetic variation in sorghum crop wild relatives. If those seeds include sorghum, you could start with this lot.
- Gendered differences in crop diversity choices: A case study from Papua New Guinea. And don’t forget gender as you do all this participatory, decentralized stuff. For example, in PNG, the women are into marketing, the men into tradition.
- Crowd breeding of Danish apple cultivars. No word on gender differences, alas.
- Modelling illustrates that genomic selection provides new opportunities for intercrop breeding. Here’s the high-tech, centralized bit, or at least a model of it, ripe for mashing up with citizen science.
- Dissection of the domestication‐shaped genetic architecture of lettuce primary metabolism. More high-tech, centralized stuff, the real thing this time. Which can now be used to breed a better lettuce, hopefully by lots of citizens growing the stuff in their gardens and providing salad tasting results through a nifty app.
- Indigenous and Local Knowledge Practices and Innovations for Enhancing Food Security Under Climate Change: Examples from Mijikenda Communities in Coastal Kenya. Maybe farmers should run participatory programmes, with scientists as the citizens.
- Micronutrient composition and microbial community analysis across diverse landraces of the Ethiopian orphan crop enset. Don’t know how you’d do citizen science on this, but I bet somebody does.
- Discovering the indigenous microbial communities associated with the natural fermentation of sap from the cider gum Eucalyptus gunnii. Someone mention traditional fermentation practices?
- The Milpa Game: a Field Experiment Investigating the Social and Ecological Dynamics of Q’eqchi’ Maya Swidden Agriculture. Citizen science is not a game. No, wait…
- The Ancient Tree Inventory: a summary of the results of a 15 year citizen science project recording ancient, veteran and notable trees across the UK. Not a game indeed: very serious, but fun, definitely fun.
Nibbles: Vavilov podcast, Pomological book, Wine press, Banana data
- Audio drama on Vavilov. You heard me.
- Proceedings from the First Annual Wild & Seedling Pomological Exhibition. First of many, I hope.
- A really old Phoenician wine press.
- Update on banana genebank data.
Lay up your dates on earth
I see Jeremy had some fun in his latest newsletter. Want more of the same, every week: subscribe.
Previously, in the Methuselah date story: around 50 years ago archaeologists excavating Masada in Israel dug up a small pile of date seeds. In 2008, to most people’s surprise, one of those seeds — roughly 2000 years old — germinated and was named the Methuselah date. Like its namesake, it proved to be male. Date male and female flowers grow on separate plants, so wails and lamentations accompanied far-fetched plans to tinker with Methuselah.
And it came to pass that in recent years another 32 well-preserved date seeds were set to germinate. And lo, six of them did germinate, and their names were given as Boaz, Eve, Jeremiah, Jonah, Judah and Uriel, and they too were of ancient lineage. And when they came of maturity and revealed unto others their gender, Eve became Adam, and Jeremiah became Hannah and Judah in her turn became Judith.
And Hannah brought forth flowers in their beauty, and the researchers carried the male seed from Methuselah unto Hannah’s flowers and the flowers swelled and were ripened. Then the researchers plucked of the fruits and tasted, and said: “The honey-blonde, semi-dry flesh had a fibrous, chewy texture and a subtle sweetness.”
The New York Times has the story, and there is a bunch of really interesting science behind some of the conjectures.
