Rio+20 is quickly approaching. Who will be going will be important. The NGO community will probably show up with sizable numbers. International organizations will be there from every possible niche of international law. And representatives of states too.
The numbers in the chart are the total number of organizations represented. Although these conference are getting larger and larger all around, NGOs have gone from less than 75 of total groups represented in 1972 to over 90% of all actors involved in 2002.
The question remains about the impact of this distribution. And if this continues, what will that mean for the Rio+20 Conference?
