Brainfood: The diverse lives and times of crop diversity
- 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.
