Adaptation of land use and houses in the upper Mekong Delta's deep flooding area

Abstract

The aim of this research is to study the current adaptation of land use and houses in the upper Mekong Delta?s deep flooding area in the present and future context. The current adaptation strategies of houses are examined in terms of location and settlement patterns, elevation of houses, durability and construction materials, flexibility, and landscape. Examining these current adaptation strategies against the projected future context, this study reveals the limitations of the status quo and challenges to the built environment resulting from changes in hydrology and the livelihoods of people. This thesis suggests that land use planning in the upper Mekong Delta?s deep flooding area should be examined in relation to hydrological phenomena and their impact on livelihoods. The study attempts a land use approach which considers flood risk, green and blue network and farmland, and the current fabric of the area. At the scale of the dwelling, it suggests the issues need to be considered, including elevation, durability, the water harvest and storage systems, and the domestic drainage and sewage systems in response to the future threats. For the community, it is necessary to create an awareness of the challenges ahead. Community-based adaptation is also a potential approach in the studied area to foster resilience of the community in dealing with change.
