Amazonian agriculture analyzed
I don’t know about you, but in my laziness I sometimes catch myself making the assumption that a centre of crop origin is also one of crop diversity. That is of course sometimes the case, but by no means always, as Vavilov himself recognized. A recent open access paper in Diversity makes the point very clearly. ((Clement, C., de Cristo-Araújo, M., d’Eeckenbrugge, G., Alves Pereira, A., & Picanço-Rodrigues, D. (2010). Origin and Domestication of Native Amazonian Crops. Diversity, 2 (1), 72-106 DOI: 10.3390/d2010072))
The authors, led by Charles R. Clement of the Instituto Nacional de Pesquisas da Amazônia in Manaus, review molecular studies and also bring in archaeological and other evidence in their discussion of the history of Amazonian crops. They come to the conclusion that these crops originated around the periphery of the region: “All but one of the species examined originated in the periphery of Amazonia (Figure 3), rather than along the major white water rivers where pre-conquest population densities were greatest.” Here’s that Fig. 3:
Now, in contrast, here’s where the pre-Columbian hotspots of diversity were to be found: “The major centers and regions of diversity are along the major white water rivers and in northwestern Amazonia, where ethnic diversity is extremely high.”
The explanation, according to the authors, is the length of time involved in the development of agriculture in the region.
Because crop domestication began thousands of years before food production systems became important, it is not at all surprising to see a dramatic contrast such as that in Amazonia.
Why was the Amazonian periphery such a focus of domestication?
It is possible that sufficient natural resources were available [in central Amazonia] so that the home gardens were such a small fraction of subsistence that they are difficult to find in the archaeological record. In contrast, in the headwaters of the same rivers in the periphery, less abundant aquatic resources may have increased the importance of home gardens.
Banana improvement at IITA explained
IITA has uploaded to youtube a longish interview with renowned banana expert Prof. Ivan Buddenhagen of UC Davis. Lots of fascinating insights, both technical and historical. What for me was the money quote comes at the beginning of the second installment (of five). Asked about what direction banana improvement should take at IITA, he says: “The first thing is to get more germplasm.” Thanks to Jacob for the tip.

- Goldman Prizewinner Jesús León Santos: “It is time we recognize that traditional agricultural methods can make strong contributions to biodiversity conservation. We should encourage it and value it as a way to produce healthy foods that conserve and care for the environment.” Time indeed.
- British twofer: The Food Climate Research Network aims “to better understand how the food system contributes to greenhouse gas emissions, and to research and promote ways of reducing them.” Then there’s the Foresight Project on Global Food and Farming Futures. Will they talk to each other, I wonder.
- From Bioversity, “European landraces: on-farm conservation, management and use.” I wonder if the Foresight Project will download a copy.
- The “Seed Warriors” trailer. Oscar buzz, I hear.
- Agricultural biodiversity heritage sites in India. Ethnobotanist brings together information on food plants used during drought. Mashup, anyone?
- A book about beer. My two favourite things. Oooh, here’s another couple! And it’s not over: Spiegel weighs in on the old chestnut about beer being the reason for agriculture. My tankard runneth over.

- “A SAARC Plant Genetic Resource Bank for rice, wheat and maize may be created to facilitate free exchange of germplasm between the member countries. To begin with, the Indian Gene Bank facilities may be utilized, with suitable modalities.” Not so heartwarming.
