- Herbaria viva: proto-genebanks of Mendel’s contemporaries in Moravia. The early 19th century living plant collections of Moravia (the world Mendel grew up in) were a kind of proto-genebank, systematically maintaining and circulating crop diversity decades before genetics had a name.
- Saving evolutionary time: Conflicting planetary temporalities in the genetic diversity debate, 1967–1980. Looking back 50 years, and 50 years after the Moravian proto-genebanks, a historian of science traces how Otto Frankel and Erna Bennett, sounding the alarm on genetic erosion in the 1960s-70s, articulated two competing visions of time and responsibility for safeguarding crop diversity, one rooted in development, the other in collective stewardship of evolution itself.
- Utilization and conservation of plant genetic resources for food and agriculture in China: a systematic review of genebanks and farmers’ seed systems. From history to present-day infrastructure. In China, genebanks and farmers’ seed systems have developed together, but gaps between formal and informal conservation remain. Otto and Erna unavailable for comment, alas.
- The effect of crop genetic diversity to food security among smallholder farmers in the global south and the role of community seed banks: a narrative literature review. Here’s the evidence on how community seed banks shape food security for smallholders, but could do more. That’s the informal system at work for you, Erna would say.
- How community seed banks contribute to climate-resilient seed systems: evidence from Ethiopia, Malawi, and Nepal. Speaking of which, a companion study looks at how community seed banks function in practice, finding they do bolster local seed security and climate adaptation, but with real limits: patchy variety availability, uneven quantities, and occasional genetic erosion of their own.
- Varietal development and rice yield growth in India: assessing IRRI’s germplasm contribution. A new assessment of the contribution of IRRI germplasm to Indian rice breeding comes in at around 11% of annual rice yield growth from 1966 to 2021. That’s the formal system at work for you, Otto would say.
- Improving low-pH and high-aluminum field tolerance in alfalfa (Medicago sativa L.). Also on the breeding front, screens of genebank collections and their derivatives for field-level tolerance to difficult soils bear fruit. Or rather, leaves.
- FAIRness at all costs? Practical limitations in applying the FAIR principles to plant genetic resources data. And finally, a reality check for the data side of all this. Applying the FAIR principles to plant genetic resources data isn’t as straightforward as the mandate suggests, with a number of practical friction points standing between the ideal and actual implementation.

Brainfood: Biodiversity works through relationships
- Plant diversity modifies multi-trophic interactions in croplands, grasslands and forests. Increasing plant diversity changes the interactions between plants, herbivores and their natural enemies, but exactly how depends on the ecosystem. Diversification’s pest-suppression magic looks like a farming-specific trick, not a universal law.
- High-resolution carbon and biodiversity mapping shows correlated losses across space and agricultural products. Carbon loss and biodiversity loss from farming turn out to hit the same ground: two-thirds of both concentrated on one-third of agricultural land, with beef and milk alone responsible for 41% of the biodiversity damage. Good news for anyone hoping one policy lever could do double duty.
- Harnessing agri-food system microbiomes for sustainability and human health. Soil to gut, it’s all one network, linking ecosystem function, food production and human health across the entire agri-food system.
- Breeding for beneficial microbial associations. If microbiomes matter that much, why not breed for them? A proposed framework pairs crop traits that recruit good microbes (root exudates, architecture) with soil practices that keep those microbes around, since good genetics on ruined soil gets you nowhere. This means designing crops as participants in ecological networks rather than as isolated organisms.
- Host genetics and social relationships jointly shape fitness-associated microbiome variation in a population of feral horses. Nature’s own microbiome-breeding program: seven years of horse poop from Sable Island shows gut microbes predict winter survival, and related horses share microbes more than chance allows. So the functional unit of adaptation is the animal plus its microbiome.
Biodiversity plans need genebanks
A new FAO policy brief analyses how the 78 revised National Biodiversity Strategies and Action Plans (NBSAPs) submitted to the CBD as of February 2026 treat agrifood systems.
The headline numbers: All 78 NBSAPs that were looked at include agrifood-related targets and actions: 63% of all national targets are implemented through agrifood-related actions, and 36% of all planned actions (4,381 of 12,332) relate to agrifood systems. I think that’s pretty good. Togo tops the list with 80% of its actions being agrifood-related, built around agroecology, sustainable forest management and genetic resource use.
The genetic resources for food and agriculture (GRFA) angle: Of the 55-item typology of agrifood actions tracked, sustainable use of GRFA appears in 74% of NBSAPs and conservation of GRFA in 70%, so both are relatively well covered. But two other pieces of the puzzle lag: inventory and characterization of GRFA sits at only 49%, and access and benefit-sharing of GRFA at 48%. So countries seem to be readier to commit to using and conserving genetic resources than to the maybe less glamorous work of cataloguing what they have or sorting out benefit-sharing arrangements.
The report’s six policy recommendations essentially argue for turning these paper commitments into funded, monitored action, particularly flagging aquaculture, agroecology, rights-based governance, and finance as areas needing a bit of a push.
This is a genuinely thorough policy analysis: 78 NBSAPs coded against a 55-item action typology is real work. But to me it was a little frustrating that twelve pages on agrifood systems never get to grips with the infrastructure that actually keeps agricultural biodiversity — the foundation of healthy agrifood system — alive. Protected areas are mentioned, but there’s nothing specifically on national or international genebanks or on-farm conservation; no Plant Treaty and its access and benefit-sharing system either. I can’t believe none of these were mentioned in the NBSAPs. Conservation and sustainable use of GRFA end up as generic line items in a typology, without much sense of what “conservation” looks like in practice, or who’s actually doing the inventorying that only half of countries have committed to.
It’s solid policy-text analysis, but it stays resolutely, almost defiantly, high-level. It’s a report on commitments on biodiversity in and for agriculture that doesn’t recognize that at least for crop diversity, a global genebank system is being built to help carry them out. Seems a pity.
Nibbles: Amaranth webinar, FARA on fonio, Maslin, Gaza genebank, Nepal seeds, Golden Triangle tea
- New webinar series from the American Society of Plant Biologists will explore how underutilized (or is it opportunity) crops like amaranth can contribute to nutrition, food security and rural livelihoods.
- FARA highlights the tiny West African grain fonio as another crop with potential to improve nutrition, strengthen food systems and create new opportunities for farmers and value chains.
- Taiwanese tea has travelled an unlikely route into northern Thailand. It too was an opportunity crop at one time.
- Ethiopian farmers may have been practising regenerative agriculture for millennia, mixing wheat, barley and other grains in the same field. The Rockefeller Foundation is on it.
- Efforts to restore the Al Qarara Seed Bank in Gaza are offering a small but significant form of agricultural recovery.
- In Nepal, indigenous seeds are losing ground to hybrids, but seed advocates are fighting back.
