About

In May 2010, Catalytic Communities launched what was originally Rio Olympics Neighborhood Watch (hence RioOnWatch), a program to bring visibility to favela community voices in the lead-up to the 2016 Rio Olympics. This news site, RioOnWatch.org, grew into a much-needed and unique reference featuring favela perspectives on the urban transformation of Rio. With diverse and deeply interlinked articles by a mix of community reporters, resident opinions, solidarity reporters, international observers, and academic researchers, we work to engender a more accurate picture of favelas, their contributions to the city, and the potential of favela-led community development in Rio and around the world.
