| Abstract | The purpose of this study is to analyze the degree of risk and vulnerability involved in landslide and flash flood community prone area in Thepparat sub-district, Sichon district, Nakhon Si Thammarat province, Thailand. The focus of this study is to analyze and understand the socio-economic of community in household level, assess risk and vulnerability of community by doing risk assessment and examine the community risk perception. All of the tasks were performed to make a measure for community based disaster risk reduction activities. In order to archive the main objectives of this research study, the research has been separated into two chapters ground on the objectives. First objective is to analyze the degree of risk and vulnerability in landslide and flash flood prone area in Thepparat community. The risk assessment has been selected to assess the risk based on the information from field survey, questionnaire survey and key informant interview. The risk analysis has been conducted by risk assessment matrix combined with Geographic Information System (GIS) to analyze the spatial data and produced landslide and flash flood risk maps. The landslide factors have been identified from the Landslide Susceptibility Index (LSI) which produce from Thai Department of Mineral Resource. Moreover, the community which prone to flash flood has been generated the buffer zone to explain the vulnerability and exposure of residents. In additional, the community risk has been displayed in clustered village zones which categories into three zones as high, moderate and low risk zones. Second objective is to examine the community risk perception involves in landslide and flash flood prone areas. The data has been collected from questionnaire survey and key informant interview in order to analyze the risk perception indicators (age, education level, monthly income, risk awareness, emergency response and controllability). Pearson correlation matrix has been performed to test the relationship between indicators. Finally, the study has been recommended the risk reduction measures which based on the result from risk analysis and the relationship from risk perception of community. The recommendations are focused on the improvements of existing programs such as early warning system, volunteer and training. There are some more things on non-structural measures to suggest such as community based disaster risk management, disaster management course in school teaching and disaster awareness. Most of the program on disaster risk reduction can be reflected to the community in order to reduce the risk and enhance the disaster preparedness and hence resilient community. |
