I have blogged here about many dangerous false cognates related to social change, such as municipio and judicialización and proyectos productivos and plataforma (search false cognate in the search bar for many more, I've been at this for a while).
Comunitario is another. In English communitarian, Webster says, means of or relating to social organization in small cooperative partially collectivist communities. Sometimes this might be what comunitario refers to - but at least in Colombia it often seems to just mean community, or community based.
