- Small farms contribute a third of the food consumed in high-income nations. And those small farms are disproportionately diverse…
- The Global Spatial Co-Variation Between Crop Diversity and Landscape Heterogeneity. …and crop diversity on farms goes with landscape diversity.
- Beyond Crop Hotspots: Why Overlooked Marginal Agricultural Lands Deserve Urgent Attention. I’m willing to bet landscape diversity is often associated with marginality, but that’s not the end of the world.
- Food Biodiversity and its Association with Diet Quality and Health Outcomes-A Scoping Review. Why should we care about diverse farms? Because diversity in your food is associated with nutritional adequacy, a reduced risk of mortality, or a reduced risk of gastrointestinal cancers. Ok, I know, I missed a step there. There was nothing in the past few weeks in the literature specifically linking farm diversity and food diversity, but you know the link is there. At least sometimes.
- Long-term agricultural diversification increases financial profitability, biodiversity, and ecosystem services: a second-order meta-analysis. Diversity on farms is not just good for (ok, maybe) diets.
- Global evidence that plant diversity suppresses pests and promotes plant performance and crop production. Another way farm diversity is useful is via pest control. Well, actually, this could count as an ecosystem service, and so an example of the above.
- Ecological drivers of intercropping performance for enhanced global crop production. Ah, that explains how those farm ecosystem services actually works.
- Crop rotations synergize yield, nutrition, and revenue: a meta-analysis. Rotations are diversification too, and good for you too.
- Revitalizing orphan crops to combat food insecurity. But of course the diversification strategy de jour is opportunity crops.
- Value chain research and development: The quest for impact. And for that revolution to happen, we’ll need a better grip on value chains.
- Cultural innovation can increase and maintain biodiversity: A case study from medieval Europe. Yes, agricultural revolution can lead to increased biodiversity.
- Household vegetable agro-biodiversity in northern Vietnam requires diversity in seed sources. Any revolution is going to need good sources of good seeds though.

Pecan inside
A peek inside Jeremy’s latest newsletter is always worthwhile…
An extract from a book usually needs a bit of context if it is to make much sense. Alas, How an Enslaved Gardener Transformed the Pecan Into a Cash Crop lacks a bit of context. It explains how “Antoine’s successful inosculation … ultimately supported the production of up to ten million pounds of pecans annually by the early 1920s, resulting in a multimillion dollar pecan industry,” and that’s good. But the extract alone tells us nothing about the enslaved man Antoine or his enslaver Roman. Still, it isn’t hard to find out more without having to read Beronda L. Montgomery’s book in its entirety, if you wish.
This also gives me an opportunity to remind you about an episode from way back in the mists of time: Pecans and history, in which I spoke to Professor James McWilliams about his book The Pecan: A History of America’s Native Nut. Chapter four is all about Antoine’s graft, though I failed to ask about that.
…see what I did there?
Genebank data at a crossroads
Is genebank data having a moment? Well, it’s a pretty big thing that the botanic gardens community have basically said that they need a Genesys too, and in a hugely co-authored “Perspective” article in Nature Plants to boot. 1
Here we have focused on the living collections data ecosystem, because many aspects to managing these collections are unique within the broader collections sector. But we can look to the more advanced and better-networked accession-level data systems of ex situ agricultural gene banks (for example Genesys), not only for inspiration but with a view to lessons learned, and ultimately as future partners in building an even broader integrated global system for ex situ conservation resources.
Hey, we’re just sitting here waiting for you to decide to join us.
And there’s other stuff going on too. The Australian Virtual Seed Bank Portal has had an update and looks just great, for example. And the Old Vine Registry‘s database has passed 4000 entries. Ok, that covers old vineyards rather than genebank collections, but same difference, don’t @ me. Anyway, would love to see it mashed up with the European Vitis Database one day.
But back to genebanks. People are even building interfaces to their data, to get cool visualizations. And they’re analyzing the data to get a handle on the composition of collections 2, to develop monitoring and evaluation frameworks 3, and to identify gaps and challenges 4. And yes, that includes challenges in data management itself.
Documentation and data management systems required more attention in all genebanks in the study, with no genebank having full passport and inventory data in a searchable data management system, although minimum passport data on 82% of accessions was publicly available in searchable databases, including WIEWS and Genesys. Good quality, well-managed and searchable data on genebank operations are important for accurate and timely decision-making. A common issue was a backlog of data entry, with eight of the genebanks in the study relying to some extent on data retained in paper copy, field books and data sheets. Searching for accession-level data is time-consuming, and paper data sheets may be lost or damaged. Data were also stored in Excel files, making it difficult to query, or genebanks had their own customized data management system that required external support to resolve problems or make improvements. Engels and Ebert (2024) recognized the weak information management systems and online accessibility of accession-level data in national genebanks as a challenge to rationalization, as well as to cost-efficient and effective conservation and use. Despite the increasing use of digital object identifiers for accessions to link accession-level data, the Third Report on the State of the World’s Plant Genetic Resources concluded that progress in the area of documentation has been limited, and training is needed for data managers and genebank managers to adopt available improved data management systems (FAO 2025c).
So, we still have work to do. But imagine what we could achieve if we teamed up with the botanic gardens. And herbaria for that matter.
