- Climate change threatens crop diversity at low latitudes. At low latitudes maybe about a third of the production of 30 major crops shifts outside their climatic niche under 2-3°C global warming, and potential food crop diversity declines on half of global cropland, but potential diversity increases elsewhere. So that’s all good then?
- Dietary species richness provides a comparable marker for better nutrition and health across contexts. Dietary species richness (DSR) can be used as a marker for the nutrition and health. If DSR is related to production diversity, I guess that could mean trouble at lower latitudes?
- Socio-economic factors constrain climate change adaptation in a tropical export crop. Actually the reduction in suitable area is 60% for banana. And there’s a decline in yield too. Unclear what that will do to DSR.
- Plant evolutionary history is largely underrepresented in European seed banks. Would be interesting to apply this specifically to crops. Or even just crop wild relatives.
- The Idiot’s Guide to Effective Population Size. Can this be usefully applied to crops? I’d like to see how banana comes out.
- Digital Revolution in Farmer Fields: VarScout Unveils Kenya’s Varietal Landscape – The Case of Potato. I’d like to see how banana comes out.
- Genetic Diversity and Distinctiveness of Common Beans (Phaseolus vulgaris L.) Between Landraces and Formal Cultivars Supporting Ex Situ Conservation Policy: The Borlotti Case Study in Northern Italy. It’s difficult, but not impossible, to distinguish — and maintain — landraces of Borlotti beans apart from obsolete and modern cultivars. I wonder if VarScout would help.
- Oaxacan Green Dent maize is not from Oaxaca. Watch out for landrace names.
- Mucilage produced by aerial roots hosts diazotrophs that provide nitrogen in Sorghum bicolor. Not just maize. And another aspect of diversity to have to worry about.
- Cryptic diversity of cellulose-degrading gut bacteria in industrialized humans. And another… What’s the interaction with DSR though?
Brainfood: Andean chefs, Tricot, Enset ploidy, Minor livestock, NUS meals, Cocoyam breeding, Millets in India, Brazilian fruits, Indian fruits
- Grains of Wisdom: Insights into the Minds of Top Chefs—A Synthesis of Expert Interviews and Literature. A good chef can make even quinoa palatable.
- Citizen science informs demand-driven breeding of opportunity crops. I wonder if tricot can make quinoa palatable. Never mind, it’s good for a lot of other things.
- Recurrent evolution of cryptic triploids in cultivated enset increases yield. Unclear if triploid enset is any more palatable than the diploid. Interesting that traditional knowledge picks up ploidy.
- Is there unrecognized potential in neglected livestock species in Sub-Saharan Africa? A systematic review of four selected species. The benefits include sustainability, nutrition and income, but not higher palatability apparently.
- Enhancing Nutrition and Cost Efficiency in Kenyan School Meals Using Neglected and Underutilized Species and Linear Programming: A Case Study from an Informal Settlement. Better palatability was not included in the linear programming, alongside such staples (geddit?) as cost and nutritional value. But it could be, right?
- Cocoyam (Xanthosoma sagittifolium (L.) Schott) genetic resources and breeding: a review of 50 years of research efforts. Unclear if enhanced palatability is a breeding aim. But it should be.
- Strengthening the millet economy: lessons from a South Indian case study. Palatability is not an issue. Drudgery is.
- The traditional knowledge about the biodiversity of edible Brazilian fruits and their pollinators: an integrative review. Presumably includes data on palatability? And ploidy :)
- Wild edible fruit utilization patterns in Garhwal himalaya (Uttarakhand, India): a multi-decadal perspective. Reasons for decline in consumption include limited traditional knowledge transfer, time constraints, migration, generation gap, and hygiene concerns. But not, apparently, palatability.
Brainfood: Ancient maize trifecta, Chinese Neolithic, Ancient silk, Sheep domestication, Ancient focaccia, Indus diversity
- The genomic origin of early maize in eastern North America. There were at least 2 eastern dispersals of ancient maize from the US Southwest.
- Archaeological findings show the extent of primitive characteristics of maize in South America. At about the same time, semi-domesticated maize also reached deep into South America.
- Maize monoculture supported pre-Columbian urbanism in southwestern Amazonia. Including the Llanos de Moxos in Bolivia, where it supported cities.
- Millets, dogs, pigs and permanent settlement: productivity transitions in Neolithic northern China. In China, it was millet that supported cities. Well, and pigs.
- Species identification of silks by protein mass spectrometry reveals evidence of wild silk use in antiquity. People in those cities had to wear fancy silken clothes, right?
- Ancient genomics and the origin, dispersal, and development of domestic sheep. Sheep domestication started in Anatolia, but that wasn’t the end of it, because there was an influx of diversity from the steppes in the Bronze Age. Nice parallel with human diversity. Different to the Chinese millet-pig story though.
- Unveiling the culinary tradition of ‘focaccia’ in Late Neolithic Mesopotamia by way of the integration of use-wear, phytolith & organic-residue analyses. You can trace focaccia way back. Goes quite nicely with roast sheep, I suspect.
- Different strategies in Indus agriculture: the goals and outcomes of farming choices. Even ancient cultures sometimes felt the need to diversify.
Brainfood: Ag and CC, Improved varieties, Yield growth, Food system transformation, CGIAR maize, Genetic erosion, NBSAPs, Technology & conservation, Cattle breeding
- Conventional agriculture increases global warming while decreasing system sustainability. The global warming potential of conventional grain agriculture has increased x8 from 1961-2020, whereas sustainability index has decreased x3. Whatever are we to do?
- Adoption of improved crop varieties limited biodiversity losses, terrestrial carbon emissions, and cropland expansion in the tropics. Crop improvements from 1961–2015 resulted in less cropland expansion, lower greenhouse gas emissions and fewer extinctions. Right, so what we need is more of the same?
- Yield growth patterns of food commodities: Insights and challenges. “The same” has meant that yield growth for dozens of crops is not slowing down. At least in the global aggregate. At least for now. At least for calories. So no resting on laurels out there!
- Governance and resilience as entry points for transforming food systems in the countdown to 2030. Especially as regards governance and resilience.
- Poverty and yield effects of CGIAR maize varieties in smallholder farming systems of Zambia. CGIAR breeders are definitely not resting on their laurels, but it looks like that won’t be enough.
- Global meta-analysis shows action is needed to halt genetic diversity loss. CGIAR and other breeders are going to need that genetic diversity that is being lost. Whatever are we to do?
- How can biodiversity strategy and action plans incorporate genetic diversity and align with global commitments? We could make better, more inclusive biodiversity conservation plans, for one thing. Which include agricultural biodiversity.
- Exploring the role of technology in the trade-off between biodiversity and poverty alleviation across countries. It would be good if those better plans included technology adoption.
- Liberalization of animal genetic resources trade and local animal productivity outcomes: A natural experiment. And yes, genetic diversity is a technology. Sort of.
