Research about religion in latinamerica

I'm about to start a research in my university about the impacts of the theology of liberation/teología de la liberacíon/ teologia da libertação in the city through the action os eclesial communities and pastoral land comissions. While I was reading about it it became impressive how it seemed to connect the churches from all around latin america so I would like to know, someone had contact with this theology in their countries and cities, it still has impact around there?
