On today’s Global Activism segment, photojournalist Paola Gianturco discusses the new, international activist grandmother movement she documents in her photographic book, Grandmother Power: A Global Phenomenon. The book reveals the lives of 120 activist grandmothers in 15 countries on five continents who effectively fight against poverty, disease, illiteracy, environmental degradation and human rights abuse.

Gianturco is a grandmother herself and was inspired to document what others are doing. She says from India to Camobodia to Argentina, grandmas are fighting for political, economic and social change. Among the numerous venues and organizations that have exhibited her work are the United Nations, UNESCO, the U.S. Senate, the Field Museum and the Smithsonian Folklife Festival.
