It’s an interesting read, and full of hope. There is clearly a demand for breeding to meet the needs of not just organic but other sorts of what might be called “proper” farming. 2 And there are young professionals who want to meet those demands. The tricky part is how to make it pay. From the brief details in the report, it seems that US government funding and private philanthropy are helping to train breeders and support specific breeding programmes, a return to plant breeding as a public good. Will that be enough?
Conservation Magazine points to a nifty idea from Australia: Fluker posts. Citizen science for monitoring landscape change. Can we get some agricultural ones?
Strangely, although the farmers are able to find promise in ancient seeds, the report claims that seeds stored at IRRI in the 1960s are too ancient to be viable. Not sure how that works.
One of the protagonists of the PBS video, Debal Deb, crops up again in another video that came to light on the PAR website. According to PAR: “This film follows the construction of a new seed bank premises in Odisha, a venture that provides a potent symbol of Debal’s values”.
With the zeitgeist firmly embracing the idea of agricultural biodiversity, preferably ancient agricultural biodiversity, as a suitable response to climate change, it is good to be reminded that droughts are diverse too. David Lobell looks at two recent scientific papers on drought tolerance. One shows very little difference between specifically “drought-tolerant” maize varieties and other varieties without the drought-tolerance genes.
To me, there are a couple of possible ways to interpret this. One is that the newer varieties being marketed by companies are not really much better in general. Or these results might indicate that the types of droughts the newer varieties were designed for are somehow different than the type of droughts they were exposed to in this experiment. In particular, as we’ve discussed in prior posts, 2012 was a drought characterized by very high temperatures and vapor pressure deficits, the kind of droughts that one expects more of with climate change.
2012, in other words, was not just a dry drought but a hot drought. The other study David looks at compares the two kinds of drought.
What’s really interesting is how remarkably low the correlation between performance in “drought” and “drought+heat” is (0.08).
While not reading too much into either study, Lobell cautions that very hot droughts may require different kinds of varieties from mere dry droughts.
On the other hand… Half of Japan’s endangered species hotspots are found in satoyama, which are under pressure. Compare and contrast with rice farming in Thailand.
