This post is well overdue but please let me introduce you to the ANU Peacebuilding Compared project and its work on reconciliation in Bougainville.
Those of you who have worked in Bougainville will be familiar with their customary approaches to conflict resolution, which were ultimately fundamental to creating peace after years of war. This story has now been captured in a thorough paper on Bougainville's peacebuilding efforts: http://www.peacebuilding.anu.edu.au/
I came across this paper following a chat with John Braithwaite, one of the architects of the project and an academic with a long history in Bougainville. John gave me some very good career advice at the time and I've long since intended to draft a post about the paper. I strongly encourage you to take a look at the website and get yourself a copy.
