In this paper, I describe our ongoing international project in engaged educational ethnography and participatory action research with young adults and consider its relevance for a discussion on the community-building role of adult education in a globalized context. I use the example of our case study to suggest that adult educators can generate viable communities by creating learning spaces that nurture critical consciousness, a sense of agency, participation and social solidarity among internationally and culturally diverse young adult learners. Furthermore, I argue that participation in international learning communities formed through this educational process can potentially help young adults become locally and globally engaged citizens. International learning communities for global citizenship thus present a proposition for conceptualizing the vital role of adult community education in supporting democratic global and local citizenship in a world defined in terms of cross-cultural and long distance encounters in the formation of culture.
