Somehow in the process of answering the question in the comment to  this blog, I managed to delete the entire Sept 9 entry. So here I am reconstructing it from memory (unfortunately I also deleted the comments):

I`ve probably talked before about participatory methods. Pictured below is an exercised called a  wealth ranking (aka poverty ranking). The idea is that community members with the help of a facilitator identify the different economic classes  in their own community  and the associated characteristics that distinguish each class.  For example one of the criteria  this group  used was number of animals owned,  with the `rich`class being seen as owning 15-20 animals,  the `middle`class 2-4 animals, and the `poor` class 0-2 animals.  A number  of other criteria are identified and outlined by the group until they are satisfied with their definitions, and then  a ranking takes place. Each group member is given seeds as counters--in this case 10 seeds per person-- and the everyone  places the sees in  the three classes according to how they think those three groups are distributed in  the community. In  the end you  get a pretty revealing picture  of the economic structure of the community.
