Application of spatial analysis in post-disaster resettlement
Post-disaster resettlement programmes are being conducted by governments and other relevant organisations to relocate displaced people to provided safe places; considering the original land standards to subsequently improve the standard of living. Although resettlement programmes have been broadly implemented within several communities who were exposed to hazards, it appears that numerous intricate problems were identified throughout their implementation. These results illustrate unsuccessful resettlement programmes which require a more effective solution. According to previous works, vulnerable hazard areas have been rarely studied in terms of displaced persons’ activities correlated between spatial and socio-economic aspects. With respect to the interaction between human and locations, humans perform their activities based upon their locations; likewise, displaced people also perform their activities based on the resettlement areas. \ud Effective applications integrated with the theoretical knowledge-base in Geoinformatics help mitigate the problems associated with the interaction between human and locations. Specifically, the spatial analysis techniques employing several scenes of high-resolution images that are carefully applied in this research in order to present an effective method to minimise the spatial and non-spatial problems in resettlement programme. A case study of Ban Nam Ko sub-district is used to gain knowledge from the resettlement activities associated with displacement locations. The explored results of this research present appropriate functions and specific conditions for displacement locations used in resettlement activities. The explored results propose potential solutions of achieving a successful resettlement programme response to debris-flow disasters. With consideration of physical, socio-economic, and administrative factors of residents and surrounding environment, this study is beneficial to governments and relevant organisations to establish displacement locations associated with activities in each resettlement phase and to setup the spatial and non-spatial database in resettlement plan for other vulnerable debris-flow hazard areas.
