EarthAction’s goal is to mobilize growing numbers of people around the world to press their governments (or sometimes corporations) for stronger action to solve global problems. EarthAction’s Network includes more than 1900 citizens groups in 161 countries, and its strategy is to create a global action alert network — a kind of Amnesty International for the planet — made up of individuals, groups and legislators who are prepared to act together on global problems. We devote particular attention to the challenge of building a more democratic and effective UN system to help solve those problems. The Joan B. Kroc Institute for International Peace Studies is a university-based research and teaching organization training young people to engage in work to build peace around the world. Our faculty and students engage in research on the causes of war and on the strategies for building a more peaceful world. Jackie Smith, associate Professor of sociology and peace studies, is working to help students and citizens learn about the World Social Forum while helping bring lessons from research in the study of social movements into practice. The Peace Caucus initiative grows from her work with groups participating in the World Social Forum and from her collaboration with the EarthAction Network, Sociologists Without Borders, and other groups. The Caucus seeks to initiate discussions between groups working on diverse issues in order to strengthen citizens' work for peace and social justice.
