Every member nation of UNESCO has a National Commission -- 192 in all. The NatCom's were conceived at the very creation of UNESCO, sixty years ago, to enable civil society to participate fully in the organization. They provide a means for educators, the scientific community, and cultural leaders to interact with UNESCO. Indeed, NatCom's often sponsor UNESCO activities in their countries, especially in developing nations.
