This document discusses principles of effective communication for disaster risk reduction. It begins by explaining that communication with communities is important so they understand hazards and risks, and can take protective measures. However, past approaches often failed to understand community perspectives and priorities. Effective communication now involves dialogue with communities to understand their experiences and ensure solutions are appropriate. While expertise from professionals is still valuable, a participatory approach that incorporates community knowledge is most effective. The goal of public education programs should be to create a "culture of safety" where risk reduction is a normal part of life, though achieving this takes a long-term process.
