The number of natural disasters in Sri Lanka has increased over the last two decades. In particular, the Indian Ocean Tsunami had a disastrous impact on communities in Sri Lanka, with 4,330 deaths and 564 persons reported missing (as of 05 April 2005) in Galle District. In order to raise public awareness of various categories of citizens on disaster reduction, the capacity building project at all community levels starting from the grass-roots level was carried out in Galle District. The initial process started from the process of trainer's training, the so-called District Workshop, and the outcome made the participants trainers in their localities and they repeated the same exercise to educate their communities in Community Workshops. The progress of the project was followed up by Japanese experts. A total of 102 Community Workshops were held in the immediate phase after the District Workshop. The practical session consists of a Community-based Hazard Mapping program of which the results were used to identify disaster vulnerable areas in community neighborhood by the participants.
