Landslides occur frequently in Sri Lanka, where there has been a marked increase in torrential rainfall with the onset of climate change. To predict a day in advance the occurrence and range of rain-induced rapid and long-traveling landslides (RRLLs), which are particularly severe, SATREPS Project RRLL has started since 2020. The project develops a system for early transmission of information predicting torrential rains and landslides and for supporting risk assessment, incorporating cutting-edge technology that predicts accumulated rainfall within a 500-m grid. As the project enters its final fiscal year in 2024, it has reached the stage at which community engagement will be promoted. The system developed in the project is subject to Internet connectivity. Therefore, mobile phones are often the only means of communication to the last mile, where Internet connection is unavailable in torrential rain in the mountains. To fully utilize the information on the predicted rains and RRLL occurrences under these circumstances, it is imperative for residents and the relevant officers who have jurisdiction over the area to know the environment in which they live. This last piece of the project’s Jigsaw puzzle is the village-watching activities involving local people and relevant officers in the project’s target study sites. This article reports the project’s outcomes focusing on the village-watching activities.
