Agrobiodiversity is crops, livestock, foodways, microbes, pollinators, wild relatives …
The Harlan III symposium, dedicated to the Origins of Agriculture and the Domestication, Evolution, and Utilization of Genetic Resources, and initially planned for 2018, is now scheduled for 3-7 June 2019. The call for abstracts and registration are open. Thanks to Anne-Céline Thuillet, on behalf of the organizing committee, for letting us know.
A paper just out in Quaternary Science Reviews provides an overview of the first 3000 years of the spread of cultivated cereals around Eurasia, based on archaeobotanical evidence. The paper has some nice maps, but the press release has a really cool animated gif, which I had no hesitation in stealing.
Here’s a quick summary:
And where are we now? Well, for that you need another new paper, this one in PLOS ONE: Regional and global shifts in crop diversity through the Anthropocene. As luck would have it, three phases here too, covering the past 50 years:
No gif, alas, but there’s a little video accompanying the press release in which the author summarizes the results.
The title of that press release says it all really: “A small number of crops are dominating globally. And that’s bad news for sustainable agriculture.” Compare and contrast with the findings of Colin Khoury and friends from a couple of years back on the increasing homogeneity of global diets. Basically looking at the same data in a somewhat different way: pretty much the same result.
Before the invention of the camera, people used watercolours to document the world. Over the centuries, painters – both professional and amateur – created hundreds of thousands of images recording life as they witnessed it. Every one of these paintings has a story to tell, but many are hidden away in archives, albums and store rooms, too fragile to display. The Watercolour World exists to bring them back into view.
And pretty fantastic it is too. Search for agriculture and see for yourself.
…this Special Volume of Plant Genetic Resources, Characterization and Evaluation is very timely as CWR science finally moves beyond the theoretical to the increasing applied, to meet breeders and consumers growing demands. It includes prioritized CWR inventories at different geographical levels viz. national (Bissessur et al., 2019; Dickson et al., 2019), regional (Allen et al., 2019; Fitzgerald et al., 2019) levels. Tools to facilitate conservation planning have also been developed (Magos Brehm et al., 2019; Holness et al., 2019), and regional conservation strategies and approaches have been developed (Allen et al., 2019; Kell et al., 2016).
Ok, the whole thing is not open access, but at least the introduction to the Special Issue is. And since I’m on the subject, there’s a nice summary just out of the state of wild Coffea in Madagascar. Coincidentally, one of the paper in the special issue is on the CWR of Mauritius, among which Coffea features very prominently.
The wild coffee species that grow in northern Madagascar are genetically similar to Coffea species found on Grande Comore in the Comoros – a volcanic archipelago off the east coast of Africa, near Mozambique. Other species have spread from Madagascar to Mauritius and Reunion Island.
