short article on Brazil nuts in Bolivia

You can get an introduction to the harvesting of Brazil nuts in the Pando Department of Bolivia - one of the most important sources of income for the people there, and indeed in other parts of the MAP region - by reading a short article by Jeff Bentley (with whose work I'm not otherwise familiar but who describes himself as an agricultural anthropologist, nicely providing a bridge between the physical and the social sciences as, of course, we ourselves aim to do in this course).
