In the latest GROW webinar, Prof. Stef de Haan, of the International Potato Centre and more recently Wageningen University and Research explains how genebanks alone won’t preserve crop diversity adequately unless linked with farmer custodians, local seed systems, and policy spaces. Sounds like he also falls squarely in the centre in the old Erna vs Otto bunfight.
To save you googling, the Rikuy Agrobio website he mentions, with the community-level tools for monitoring crop diversity, is here. And you can explore potato diversity in on-farm hotspots on wikiPapa here. Both only in Spanish so far, but well worth looking into. Fascinating stuff, and obviously valuable, but I do wonder how to scale up this sort of thing to all crops, everywhere.
