- The Economist says (we paraphrase) war is good for biodiversity conservation … but where are the wild relatives?
- Right here, in the boreal north, and we need to conserve it, and the knowledge to use it, say Canadian conservationists.
- Rainfall, not temperature, was the trigger for C4 grasses say other American boffins.
- “It’s a sloppy use of language to equate vegetables and food,” says Rachel. We agree.
Tying up some Amman loose ends
You’ve been wondering about those as yet unanswered questions from the Amman conference, haven’t you? Ok, here goes.
Jose Cubero asked why there are no commercial faba bean hybrids. He had no answer. The yield gain is considerable. BTW, did you know that protein content in faba bean is not negatively correlated with yield potential, as is apparently the case in other pulses? And that you can have totally selfing varieties, with closed flowers? I need to learn more about this crop.
Raj Paroda asked if aeration might be the answer to decreasing methane emissions from paddies. Well, it’s possible. Work in Japan is showing that prolonged mid-season aeration can cut methane emissions down to zero. But what will this do to yield? And what will it cost? Of course, “[m]any rice varieties can be grown under much drier conditions than those traditionally employed, with big reductions on methane emission without any loss in yeild. Additionally, there is the great potential for improved varieties of rice, able to produce a much larger crop per area of rice paddy and so allow for a cut in the area of rice paddies, without a cut in rice production.” See? Even when it’s not about germplasm, it’s really about germaplasm.
Theib Oweis wondered whether we shouldn’t measure — and select for in breeding programmes, by implication — productivity on the basis of unit of water consumed rather than of land used. Indeed we should, certainly in the dry areas. Potatoes had the highest yield per cubic meter of water of the crops on his list, and olives the highest economic return per cubic meter of water. You can get 8 t/ha of wheat, but the highest water productivity is actually at 6 t/ha. You need 1000 kg of water to grow 1 kg of wheat. I could go on and on, he had lots of figures like this.
And would you believe it, Ken Street did indeed think of a better way of identifying germplasm for evaluation, and it’s called FIGS.
How many did you get?
Online map of interaction between climate change and population
Population Action has an interactive map which mashes up climate change (including its effect on total national agricultural production) with population dynamics. Here, for example, is the result for Africa. ((Sorry about the quality, I can’t see an easy way of downloading a decent image, but the thing looks well enough on the website itself.))
The source of the agricultural production data is a 2004 crop modeling study by the Godard Institute for Space Studies distributed by CIESIN. ((The BBC’s mashup of climate change, population and industrialization seems to use different data, and goes to sub-country level.)) Worth taking the guided tour to start off.
You can’t imagine how many different versions of this sort of map have been on show here in Amman at the conference on food security in the drylands. Somebody ought to do an inventory…
Mapping European alcoholic diversity
A map over at Strange Maps seems to suggest that the most diverse place in Europe in terms of drinks traditions is the area where Hungary, Romania and Ukraine — and thus the wine, beer and vodka belts — meet. Check it out:
But is it true? Have any of our readers been there? And can they recall anything about the visit?
