Abstract
Risk-Sensitive Land Use Planning (RSLUP) is the process of mainstreaming disaster risk management parameters in land use planning. To ensure the effectiveness and sustainability of RSLUP, it is necessary to identify and understand the existing risk sensitivity of the land use plan. This research aims to develop a GIS-based multi-criteria zoning approach for mapping earthquake risk sensitivity of the land use plan of a local level area. For this purpose, Uttara Residential Model Town (URMT) (third phase), Dhaka, Bangladesh has been selected as the study area considering its earthquake risk for exposure to a potential earthquake. The methodology applied in this research is comprised of two steps. Firstly, assessment of the spatial earthquake risk sensitivity of the proposed land use plan of the study area based on the risk themes and corresponding risk attributes including both natural characteristics as well as built environment factors. They are macro-form risks (seismic hazard assessment), risks in urban texture (proximity from primary roads), special risk areas (geomorphic suitability and proximity from waterbody), open space scarcity risk, and risks in critical facilities (potential temporary disaster shelter and health facilities). Secondly, preparation of earthquake risk sensitivity zoning map by overlaying the spatial risk attribute maps based on weights determined through Analytical Hierarchical Process (AHP). This research brings out the importance and a methodology to assess risk sensitivity of the land use of an area at the local level, which can further foster sustainable RSLUP reflecting the risk sensitivity accordingly and effectively.
