Abstract:Although many activities relating to community based risk assessment of different hazard types are currently undertaken, only a few of these activities actually focus on debris flow hazards. This study is located in the small town of Villa Restrepo, Colombia .This town is placed on the fan of three river basins (La Sierra, El Salto and Gonzales river basins) and is a hazardous place because along the history several debris flow events have occurred affecting lives, causing economic loss and disruption of activities. Due to scarcity of information on this area, this research attempts to develop a community based methodology for debris flow assessment and management with hazard, vulnerability, risk perception and local adaptation capacity integration. Villa Restrepo people’s experience, knowledge and participation in dealing with the debris flow hazard are key information resources to carry out this research. Furthermore the application of different tools and methodologies in this study were aimed to provide new ideas to solve a problem related to poor environment information. This research attempts to develop a community based methodology for debris flow risk appraisal for local risk management using Villa Restrepo as a case of study. The proposed methodology develops approaches for assessing hazard, vulnerability, risk perception, risk estimation and identifies and evaluates local risk reduction scenarios. The present research is aimed for local municipality activities and planners applications considering mostly activities related to debris flow risk management , mitigation and preparedness and as well as an important support document for studies related with debris flow risk assessment on small scale study area with scarcity of base information.
