[...] Radio stations and newspaper advertisements were mentioned by both victims of trafficking and migrant workers (either in the Plurinational State of Bolivia,2 or in Argentina on the local radio stations of the Bolivian diaspora) and may provide very useful access points for these populations for future interventions. [...] Both groups of interviewees noted the negative impact of the harsh environmental conditions, including the extreme cold and heat and the presence of dust.
