- The Chinese Academy of Agricultural Sciences genebank fills some gaps.
- I wonder if any of those new accessions are “opportunity crops.”
- Because they are sorely needed, for example in Africa.
- Which is not to say working on staples like maize isn’t cool. Just ask Jeffrey Ross-Ibarra.
- Working on sweet potato can also be, well, sweet. Case in point: gorgeous book on the varieties of the Canaries.
- There’s an opportunity to help the Land Institute with its research on perennial crops.
- And yes, seeds are indeed alive. Just ask CAAS.
Diversifying rotations for climate change adaptation and mitigation
Jeremy’s latest newsletter summarizes a summary of a roundup of rotation research from northern China. Bottom line: more crops better.
Anthropocene Magazine has a handy summary of recent research into crop diversity on the North China Plain. Bottom line: adding more crops to the current dominant rotation of wheat and maize increases yields and profits, sequesters more carbon in the soil and reduces overall greenhouse gas emissions.
The researchers added sweet potato and a legume, like soybeans or peanuts, to the rotation and at the same time reduced the amount of synthetic fertilisers applied to the field. Sweet potato is a cash crop that increased farmers incomes by about 60%. Soybeans and peanuts have a lower impact on incomes (13–22% increase) but more than compensated for lower fertiliser inputs. Not surprisingly, lower nitrogen fertiliser results in lower emissions of nitrous oxide, a greenhouse gas. What was a surprise was an increase in carbon in the soil, perhaps because diverse crops result in more diverse microbial populations which in turn trap atmospheric methane and carbon dioxide.
[D]eveloping and adopting diversified cropping systems should be a key consideration in agricultural policy setting and a top priority for on-farm decision-making.
Projecting the experimental results to the whole of the North China Plain could, the researchers say, increase cereal production by 32% and reduce the need for fertilisers by 3.6 million tonnes. That alone, they say, would reduce China’s greenhouse gas emissions by 6%. And annual farm incomes would increase by 20%.
Nibbles: Genebanks double, Rice landraces, Millet demo, Taro system, EU Seed Law, Food crisis
- Why seedbanks matter.
- But are they hyperlocal?
- Why local rice varieties matter in Bangladesh.
- Why millet matters for climate resilience.
- Why taro matters in Hawaii.
- Why EU seed laws matter.
- Why diversification of food systems matters. Among other things.
Nibbles: Public breeding, Millet Man, Strampelli museum, Ghana community seedbanks, genebank trifecta, CWR, Illegal Canadian potatoes, Açaí GI, Mayocoba bean, Spartan Actinidia, Bitters
- Public sector plant breeders are disappearing.
- The Millet Man of India is still there though. And why he’s important.
- A museum to public sector breeder Nazareno Strampelli appears in Italy.
- Another couple of community genebanks appear in Ghana.
- We can never have too many discussions on the importance of genebanks, so here’s another one. Not much on the community sort, though. Here’s another example: Ireland. Even the Arab States of Asia want one!
- And a deep dive on crop wild relatives in genebanks to round things off.
- A community saves illegal potatoes in Canada. Yeah, I know, there’s a lot to unpack there.
- Maybe that humble illegal potato needs a geographic indication, like that superfood, açaí.
- The Mayocoba bean as a superfood is a bit of a stretch, but there’s plenty of other pulses out there making waves.
- The Michigan State kiwi could probably do with a geographic indication too, come to think of it. Cold-hardy and smooth-skinned? Super!
- Ok, this is probably the last Nibbles before Christmas, so let’s celebrate with a drink: with bitters of course.
