I attended the World Social Forum (WSF) in Belém, Brazil, from January 27 - Feb 1, 2009 with the Network Institute for Global Democratization. Writings from previous forums are available on my Trip Reports page.
"Snubbing Davos: The Presidents at the World Social Forum," NACLA Report on the Americas 42, no. 3 (May/June 2009): 4-5.
The World Social Forum Returns to Brazil, Upside Down World (February 5, 2009)
I've also assembled a page on Indigenous peoples at the forum.
For a good introduction to the Forum, see Mario Osava, "World Social Forum: Crisis as Opportunity for 'Another World'" (Interpress Service, January 21, 2009)
