Analyzing Urban Intensification and Disaster Risk Reduction using the Optimal Land-Use Model

This study developed an optimal land-use model composed of multicriteria: tsunami risk, infrastructure maintenance cost, traffic time with controlling population, land use, and commuting trips. The model was applied to a coastal area in Japan. The results, with various combinations of the control variables, showed that the larger the number of variables, the more concentrated residential areas became with fewer costs. The findings urge consensus around trade-offs between urban intensification and disaster risk reduction.
