N2 - In recent decade many floods occurred in Laos. In order to reduce the impact and losses from flood events, it is important to understand the magnitude of flood and its future potential impact areas. Land use change and climate change have played a significant role and it is important to understand the impacts of flooding. The land slide is another hazard that can occur after flooding. Therefore, flood hazard mapping serves as an important tool for decision-makers to understand the sensitive areas. We have developed an integrated hazard based on the combining 3 hazard maps which are a flood, land use change and climate change hazard map. Analytical Hierarchy Process (AHP) is the tool for multi criteria decision making. This method used AHP as a tool to integrate the different hazard maps into an integrated hazard map. AHP is used to provide the relative weights of each hazards map. It is necessary to understand the relative importance of each hazard map, by using the pairwise comparison matrix to compare their significance. The value of each row in pairwise comparison was determined based on the judgment of experts. The result shows that around southern and central of Laos have a high hazard. Then we compare our result with historical record to validate our study.
