Detoxifying cassava prompts Ford to ask interesting questions:

I knew about the value of cyanide to deter theft and pests and have also read that it’s a useful pool of nitrogen for the root, but reducing “the social obligation to share” is interesting. As I recall, “Famine in Peasant Societies” puts part of the blame for famines on the expectation that anyone who gets a little ahead will share with relatives, rather than investing in irrigation equipment or whatever. Bank accounts, even if they don’t pay interest, offer a way to hide resources from relatives so, the book claims, famines became less likely. Still, do the risks of sharing outweigh the benefits? Or is there some optimum level of sharing?

One for the game theorists?

Multimedia cacao

A couple of days ago we Nibbled a set of cacao photos from Sustainable Harvest International. I thought at the time it probably deserved better exposure, and I’m happy to be given the excuse to provide it by the appearance on YouTube of a sweet little cartoon on the cacao tree, courtesy of Kew. And by the start of a series of posts on how chocolate is made, by Rachel Laudan.

And speaking of cacao, this just in: A London hedge fund last week took delivery of contracts for about 7% of the world’s cacao producction, according to a report in The Guardian. (h/t The Tracing Paper). Coincidentally, or not, the price of cacao has increased 150% over the past 18 months.
