- Saving the scrub lupine. Well, it’s a crop wild relative of sorts.
- Dietary approaches to reduction of belching. No, not less beer and peanuts in front of the TV.
- “Governments and institutions should strongly promote new agricultural technologies suitable for smallholders through increased investment in crop breeding and livestock research.” That would be IFPRI on the actions needed to prevent recurring food crises. Hope that includes supporting the genebanks.
- “Can’t nutritionists make up their minds? They keep changing things!” Nuff said.
- Carrots are exotic? In Canada? Yes indeedy.
- Rachel dissects the cost of proper poi in Hawaii.
- Behold Barhal, relative of breadfruit.
- High yielding mung-bean repatriated to Somalia. Genebanks protect and serve?
- Do your bit for conservation, eat an invasive. Or, perhaps, a bison?
- Bad news for Indian mangoes. What I want to know is whether there are any varieties that are doing really well.
- Mediterranean forests going up in smoke. Bad for the crop wild relatives in them too, no doubt
Mapping drought risk
Just a quick follow-up to the rhyming couplet on water-related stresses in the just-published Brainfood. The Center for Hazards and Risks Research (CHRR) at Columbia University, which we have mentioned here before in connection with tsunami risk, also has data on Global Drought Hazard Distribution.
With a little R-related effort by Robert 1 you can get a Google Earth file, which looks like this for Asia. 2 I’ve also added MODIS fire hotspots for the past 24 hours, merely because I can. That would be the little fire icons.
And that means you can mash up drought risk with germplasm origin (from Genesys, say), in this case from Chad as an example.
Which is a great thing to be able to do because as we have just had reconfirmed by our friend Dag Endresen, the origin of germplasm allows you to make some predictions about its performance.
Brainfood: Chia, Lentils, Bambara groundnut, Cacao, Amaranths, Rwanda, Cherimoya, Conservation, Drought, Plasticity, Phenology
- Extending the range of an ancient crop, Salvia hispanica L.—a new ω3 source. So we can grow it in the US, natch.
- Characterization of the lentil landrace Santo Stefano di Sessanio from Abruzzo, Italy. In the market, some are not what they claim to be; I’m shocked.
- Genetic diversity in Bambara groundnut (Vigna subterranea (L.) Verdc.) as revealed by phenotypic descriptors and DArT marker analysis. They’re pretty diverse, especially in Cameroon/Nigeria, which may be where they were domesticated.
- Genetic diversity and spatial structure in a new distinct Theobroma cacao L. population in Bolivia. They’re different from other cacao populations, and probably indigenous to Bolivia.
- Systematics and taxonomic delimitation of vegetable, grain and weed amaranths: a morphological and biochemical approach. Relationships? It’s complex.
- First and second millennium a.d. agriculture in Rwanda: archaeobotanical finds and radiocarbon dates from seven sites. Earliest pearl millet (Pennisetum glaucum), finger millet (Eleusine coracana) and sorghum (Sorghum bicolor) in the region, but do they really mean AD?
- The use of consecutive micrografting improves micropropagation of cherimoya (Annona cherimola Mill.) cultivars. It does, what more can I tell you?
- Social and ecological synergy: Local rulemaking, forest livelihoods, and biodiversity conservation. Big meta-analysis reveals complexity and the importance of participation by “local forest users.”
And here are a trio of rhyming couplets, if you see what I mean:
- The relative importance of drought and other water-related constraints for major food crops in South Asian farming systems. Drought and water constraints are widespread in South Asia. Though they contribute no more than 20-30% of current yield gaps, investment in genetic solutions needs to continue. Alas, there are significant Challenges in breeding for yield increase for drought. Nothing that can’t be overcome, though.
- Rethinking species’ ability to cope with rapid climate change. It’s the plasticity, stupid.
- Meta-analyses suggest strong selection on flowering phenology both in plants in general and in chickpea in particular.
The climate–demography vulnerability index of my mother-in-law
Another dispatch from the outer reaches of GISland. Yesterday’s post on the likely consequences of climate change around my mother-in-law’s farm in Kenya got me thinking that it would be nice to see where that locality fits in the global vulnerability scene. One can actually do that thanks to a recent paper in Global Ecology and Biogeography. 3
The authors start by calculating something they call Global Climate Vulnerability Index (CVI)
…by combining climate change forecasts with current relationships between human density and climate. We further refined the CVI by contrasting predicted vulnerabilities with demographic growth rates to create a climate–demography vulnerability index (CDVI) reflecting the spatial disparities between demographic trends and climate-consistent population growth.
The global map of CDVI is Fig. 5 in the paper. But how to get that into Google Earth? Thanks to the raw GIS files from one of the authors, and some R magic from friend and occasional contributor Robert, I now have a kmz file of CDVI, on top of which I can easily plot the location of the mother-in-law’s spread at Gataka near Limuru. In the map below, dark blue is bad, light blue less so.
Gataka turns out to have a slightly positive CDVI.
Highly negative values [of CDVI] … represent low-vulnerability situations where current demographic growth is much lower than climate-consistent population growth, while highly positive values … represent high-vulnerability situations where current demographic growth vastly exceeds climate-consistent population growth.
So, bad news for the mother-in-law, but not actually as bad as I feared. I wonder if I can persuade her to diversify. Perhaps into indigenous leafy greens. And sorghum, as maize seems to be heading for trouble. SPAM says sorghum should be the main crop here anyway. It may yet turn out to be right.
