Genebanks and climate change adaptation

Gary Nabhan has had a letter published in the Christmas edition of The Economist.

SIR – Your otherwise excellent leader on adapting to climate change was marred by the assertion that people should abandon their “prejudice” against genetic engineering in order to secure food supplies (“How to live with climate change”, November 27th). Although it is true that drought-resistant seeds will be needed—as will low-chill fruit trees and root crops—they are not likely to come from genetic engineering. This is because it can cost up to $5m and take up to 15 years of R&D for each new patented biotech cultivar. It is unlikely that genetically engineered organisms can be deployed quickly enough to respond to climate change.

It would be far more cost-effective to support local farmers in their breeding and evaluation of selected varieties already in community seed banks. The diversity of heirloom seeds offers rural communities far more pragmatic options than the Gates Foundation and Monsanto can generate with all their wealth.

I won’t comment on the GMO angle, except to say that Gary’s point is debatable. What I wanted to point out is that it’s not just “community seed banks” that house the seeds of adaptation to climate change. 1 National and, in particular, international genebanks will also be important. That’s because the climates experienced by rural communities in the future will increasingly come to resemble those experienced in the past by communities further and further away. Adaptation will lie in other people’s seeds.

Mapping rice agrobiodiversity from around the world

Ooooh, nice article from our friends at IRRI on mapping rice genebank accessions, something close to our hearts here at the Agricultural Biodiversity Weblog, as regular readers will testify.

I guess the main point made by the money map, reproduced below, is that while IRRI may be managing on behalf of us all (under Article 15 of the International Treaty on Plant Genetic Resources for Food and Agriculture, no less) the largest and most diverse collection of rice germplasm in the world, it doesn’t have everything.

Problem is, not all of those other genebanks which nicely complement the IRRI collection make their material quite so obviously, freely and officially available to others. Plus, of course, we need the data from CIAT, EURISCO and all those other national genebanks. Genesys will help with that, hopefully, eventually. In the meantime, for comparison, this is what it now sees 2:

My eye was inevitably drawn to the outliers on that IRRI map. What is that northernmost collection, maybe in Kazakhstan? And alas the southernmost collection seems to have been cut off.

Anyway, now for the gap-filling!
