New discursive arenas among transnational communities are transforming communication processes both within and beyond national boundaries. Focusing on one of the most diverse and populous Spanish-speaking populations in the United States, we explore five community media publications in Miami-Dade County, Florida, created by and for several distinct Latin American immigrant communities. Through content analysis, we explore articulations of immigration and the environment, issues that are global in nature, but experienced locally. By asking how immigrant media cover environment and immigration, whether or not coverage reflects transnational dimensions, and what this implies for new forms of civic engagement and governance, the results provide insight into the new discursive arenas flowing across borders, critical implications for notions of citizenship, as well as conceptualizations of public opinion legitimacy and efficacy.
