Despite efforts to include residents in hazard management, their contributions are often undervalued because they are seen as passive recipients of intervention rather than active participants in the production of knowledge, particularly when they lack technical expertise. However, using multiple perspectives and experiences can improve hazard management strategies and create safer communities. This paper examines a Colombian landslide management program to highlight the prospects and limitations of incorporating non-expert knowledge into hazard management. The Guardianas de la Ladera (Guardians of the Slope) in Manizales, Colombia is a program in which female heads of household are hired to maintain landslide-prevention infrastructure and communicate landslide risk to the community. While the highly regarded program is perceived as having reduced the frequency of landslides and associated damages, the hierarchical institutional structure inhibits bottom-up communication, including information that could improve long-term vulnerability reduction. We argue that regardless of the location, scale, or specific hazard being addressed, incorporating non-expert knowledge into hazard management potentially illuminates sources of vulnerability not recognized by technical or development experts.
