- 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?

- What has agrobiodiversity ever done for us? Kent Nnadozie of the Plant Treaty lays it out.
- Michael Frei of the HealthyDiets4Africa project doesn’t need it laid out.
- Neither do the people who awarded a prize to Charlotte Allender of the UK Vegetable Genebank.
- What has the US National Plant Germplasm System ever done for anyone? The Guardian, the NY Times and NPR News lay it out. I guess someone in D.C. needs it laid out, but will it make any difference?
- Everyone: Potatoes in Florida! Breeders: No problem. NPGS: You called?
- Here’s The Guardian again, but this time thinking it is making the case for not putting seeds in the fridge, whereas in fact it’s making the case for the complementarity of ex situ and on-farm conservation.
- Speaking of on-farm conservation, here’s a couple of pieces on community seed banks in Guatemala.
- Speaking of on-farm conservation, here’s the heart-warming story of Welsh organic farmer Gerald Miles.
- Meanwhile, the World Vegetable Centre opens a new genebank.
- And Türkiye hosts an international, no less, olive genebank.
- And genebanks can be so beautiful, like works of art. Former Tate Modern director Vicente Todolí lays out his citrus samples. I wonder what he could do with olives.
- Botanic gardens are beautiful and often act a little bit like crop genebanks. Here’s an example from Portugal I stumbled onto recently, I forget how.
- You know what I’d like to see? An international pepper genebank, that’s what. No, not the kind that might be in those Guatemalan community seedbanks or the WorldVeg genebank. This sort of pepper. Piper pepper.
- I bet the ancient Egyptians had pepper. Egyptian archaeologist Mennat-Allah El Dorry lays out what else they had.
- Maybe you could lay out world history using pepper. You can definitely do so using cacao and chocolate.
- No, not using ancient DNA, but actually…
Third global assessment of PGRFA sees the light of day at last
I spent all last week at the 20th Session of the FAO Commission on Genetic Resources in Rome: “[t]he Commission is the only permanent intergovernmental body that specifically addresses all components of biological diversity for food and agriculture.” As ever, there’s a great summary of the session at Earth Negotiations Bulletin. Maybe the most significant milestone was the launch of the Third Report on the State of the World’s Plant Genetic Resources for Food and Agriculture, 15 years after the second report. FAO has a nice summary of the key findings. You know how we have been saying that there are 1750 genebanks in the world? Well, we can’t say that any more: due to a tighter definition, there are now 867 genebanks.
If you want some more fun numbers, elsewhere I have blogged about how the work of my own organization, the Global Crop Diversity Trust, is featured in the report.

- 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.
Brainfood: QMS, Seed viability, Genotyping, Taxonomy, FAIR data, Evaluation data, Lentil data, Indian cryobank, Home genebank, Dry chain, Botanical gardens, Environmental monitoring, Bending the curve
- Quality management in a genebank environment: Principles and experiences at the Centre for Genetic Resources, The Netherlands (CGN). Do we need a certification system for genebanks? We do have the means to put one together.
- A pragmatic protocol for seed viability monitoring in ex situ plant genebanks. But will genebank certification allow much-needed flexibility?
- Genotyping Genebank Collections: Strategic Approaches and Considerations for Optimal Collection Management. Or will it make everyone genotype everything?
- Assigning Species Names to Ambiguous Populations in the US Potato Genebank. Oh, you want an example of why everyone should genotype everything?
- The FLAIR-GG federated network of FAIR germplasm data resources. For sure it should require data to be FAIR.
- The EURISCO-EVA Information System, an innovative approach to the data management of multi-site crop evaluation data. Even evaluation data, though? That usually comes from genebank partners, not the genebanks themselves. Wouldn’t that be a problem?
- A case study on lentil to demonstrate the value of using historic data stored in genebanks to guide the selection of resources for research and development projects. Oh, you want an example why evaluation data should be included in (or linked to) genebank documentation systems?
- Indian cryogenebank conserving diverse plant genetic resources for the last three decades: Achievements and way forward. Is it certified, though?
- Share a Tiny Space of Your Freezer to Preserve Seed Diversity. Meanwhile, at the other end of the technology continuum…
- Applications of dry chain technology to maintain high seed viability in tropical climates. If your freezer is in the tropics, think about handling your seeds this way. And maybe you’ll get certified :)
- Insights from a century of data reveal global trends in ex situ living plant collections. Maybe botanic gardens should be certified too, presumably. Would it have made a difference? Actually, now I think of it, does this mean the system as a whole needs to be certified? Anyway, good thing the data were FAIRish.
- A framework for long-term environmental monitoring using living plant collections in botanic gardens: A global review and case study from Trinity College Botanic Garden. Another example of the benefits of FAIR evaluation data. And of botanical gardens.
- Sustainable high-yield farming is essential for bending the curve of biodiversity loss. And genebanks (and maybe botanical gardens too, why not?) are essential for sustainable high-yield farming. Certify that.
