El cambio de paradigma en la cobertura informativa de la gestión de riesgo de desastres Marta Milena BARRIOS Jesús ARROYAVE CABRERA Lina VEGA-ESTARITA Comunicación amenaza desarrollo medioambiente América Latina periodismo de prevención Este artículo analizó la cobertura de la gestión de riesgo de desastres en tres regiones de América Latina para conocer si el cambio de paradigma, de pensar el riesgo como una construcción social en lugar de enfocarse en el desastre, se veía reflejado en las narrativas periodísticas. Mediante un análisis de contenido de 130 noticias se demostró que la redacción presenta vicios como privilegiar fuentes oficiales y comunicados de prensa o contar los hechos sin análisis ni contexto. Se evidenció que el énfasis permanece en el desastre, lo que representa una oportunidad de ejercer un periodismo de prevención, que presente la GRD como un tema transversal en la agenda mediática, alineada con temas del desarrollo como pobreza, corrupción o salud. 2017 artículo científico 1390-1079 https://www.redalyc.org/articulo.oa?id=16057380009 https://www.redalyc.org/journal/160/16057380009/ https://www.redalyc.org/journal/160/16057380009/html/ https://www.redalyc.org/journal/160/16057380009/16057380009.epub https://www.redalyc.org/journal/160/16057380009/movil https://doi.org/10.16921/chasqui.v0i136.3318 es http://www.redalyc.org/revista.oa?id=160 Chasqui.
