Media representations of environmental issues: From scientific to political discourse

IntroductionThe media is considered to be a social agent that intervenes in the elaboration of social representations of environmental issues.ObjectiveThis research analyses media representations of environmental issues and how they have been constructed and transformed from the Rio Summit in 1992 to 2006. The authors adopted a constructionist approach based on the theory of social representations (Moscovici, 1961/1976) to describe the generation of information by the mass media.MethodA sample of 1039 news articles from two Spanish newspapers (La Vanguardia and El País) was analysed. The period of study ranged from the Rio Earth Summit to several years after the Johannesburg Summit (1992–2006), and the study analyses both the content and form of the environmental news.ResultsThis longitudinal study shows not only an increase in environmental news during the period of analysis but also an increased variety of themes addressed and represented. The results evidence significant urban problems in recent years. The environment has shifted from being associated with nature to being predominately associated with the urban environment.ConclusionThe results suggest that there has been a movement from scientific to political discourse and a change towards greater reflection and social recognition of the relevance of environmental issues.
