I designed two six-minute videos, a public officials video, and a flood victims video. The videos were incorporated into surveys with the target population, which took place from September to November 2021. Both videos contained the same information. The visuals in the videos alternate between the speakers, images, and video recordings that help convey the message. Publicly available images and recordings of local news outlets were used for this purpose. The same visuals were used in both videos. The standard Portuguese versions of the videos were also dubbed in Chuabo, the most common local language, to promote inclusiveness among all ages and education levels. In the public officials video, the information was delivered by local government officials (one man and one woman) responsible for disaster risk management. The flood victims video featured two residents (one man and one woman). These actors drew on their recent flooding experience to deliver the information. Finally, to measure the effectiveness of the interventions, I created a placebo video. This six-minute video contained general information about Quelimane, its history, and its main economic activities. This information was delivered by residents, contained images and video recordings, and was also made available in Chuabo.
I designed a set of six text messages summarizing the key points of the videos. The text messages were sent daily to chiefs and households in selected city blocks from November 19 until November 24, 2021.
