Congratulations to our friend and colleague David Williams. He was co-author on a paper about ancient squash seeds that made Archaeology’s Top 10 Discoveries of 2007. Sorry we didn’t catch it earlier…
Taro in the Indo-Pacific
The 19th Congress of the Indo-Pacific Prehistory Association is going to take place 29 Nov.-5 Dec. 2009 at the Vietnam Academy of Social Sciences Conference Centre, Hanoi, Vietnam. One of the suggested sessions is on taro:
Wet Cultivation of Colocasia esculenta in the Indo-Pacific: Archaeological, Technological, Social, and Biological Perspectives.
David Addison (American Samoa Community College) and Matthew Spriggs (Australian National University)
add1ison(at)gmail.com; matthew.spriggs(at)anu.edu.auWet cultivation of taro (Colocasia esculenta) is among the most productive traditional agricultural techniques in the world, rivaled only by the homologous systems based on rice (Oryza sativa). Some of the largest stone constructions in the Pacific relate to wet taro cultivation. Research on wet taro in Oceania has focused on: the role of agricultural intensification in development of political and social complexity; aggression and territoriality; risk management; and initial island colonization. This session seeks to bring together researchers from across the Indo-Pacific region to discuss the wet cultivation of Colocasia esculenta from diverse perspectives. Participants will be asked to have papers ready for posting to a website by 1 October 2009. This will give everyone a chance to read each other’s ideas in detail. The IPPA session will then consist of short presentations and ample time for discussion. Selected participants will be asked to revise their papers immediately after the conference for publication in an edited volume scheduled for early 2010.
Thanks to Lois Englberger for the tip.

Domestication trifecta
We’ve blogged a number of times about the paradigm shift that’s occurring among students of plant domestication, driven by increasing interaction and synergy between archaeologists and geneticists. The idea of “rapid, localised” domestication is down if not out: all the talk these days is of domestication as a protracted, multi-locational and biologically complex process.
Well, there’s a very nice review of the history of this shift in Trends in Ecology and Evolution, at least as it concerns the crops domesticated in the Fertile Crescent. It is only very recently that geneticists have looked at their molecular data in the light of archaeological results and realized that there were other ways to interpret them apart from the conventional idea of domestication in one place over the course of a few human generations.
Meanwhile, a paper in Annals of Botany looks at another source of data, i.e. written sources. Chinese investigators have looked at references to eggplants in ancient encyclopedias, concordances and even poetry, and charted changes in size, shape and taste over the past 2000 years. The oldest reference dates back to 59 BC, and since then the Chinese eggplant has gone from round to a variety of shapes, has increased dramatically in size, and has become much sweeter.
Finally, our friend Hannes Dempewolf and co-authors have a paper in GRACE which looks in detail at domestication in the Compositae. Why have only a handful of species in this family been fully domesticated? Secondary defence compounds, inulin as a storage product and wind dispersal, the authors suggest.

- New Gene Conservation is out. Put out more flags.
- Biofuel from coffee grounds? Right. Hope the stuff was shade-grown, anyway.
- Is a lupin or date palm seed the oldest ever found? Let the controversy rage.
- Bees scare caterpillars as well as pollinating plants. Thankfully, Europe is on the job, colony-collapse-wise.
- Trouble for Scottish farmed salmon. And the wild ones may have their problems too. But aquaculture in general is booming, they say.
- Google Earth discovers forest. Not agrobiodiversity, but fun nonetheless.
- “It doesn’t just take in seeds – it sends them out.”
- Maize pest will love climate change. Well, some of them anyway.
- The latest review of earthworms discussed.
- Jellyfish and chips?
- Eating local pretty much unavoidable in Cuba. Yes, everyone wants to be a locavore these days.
- Japanese amateur botanists get into genebanking.
- “108 dishes based on jackfruit and seed varieties that are facing extinction were also exhibited at the festival.” 108?
- Queensland markets its tropical produce via a new website. No reason why others shouldn’t do the same, is there?
- “People shouldn’t underestimate how important a goat can be for a family in Africa.” Having had to assist in slaughtering one over Christmas, I certainly don’t.
- A rapid run-through the history of chocolate.
- Long-fallow agriculture in Mali leads to more, more diverse and taller trees.
- Global accessibility map published. Also one of fires, and intact forests. Let a thousand agrobiodiversity mash-ups bloom. Thanks, Andy.
- Nepal has lots of medicinal plants. Funny they don’t seem to feature in the Western Terai Landscape Complex Project.
