Outline of Final Research Achievements

This study simulates and verifies the possibility of housing development alternatives in the areas attacked by a landslide disaster in Izu Oshima and Hiroshima. As a result, it was quantitatively confirmed that it is possible to select a suitable residential area outside the landslide disasters site by using three planning methodology: 1.Landscape planning methodology which is based on land use continuity, 2.Ecological planning, 3. Swarm planning.　The damaged area was reduced from 50% to 20%. And social cost of damage to houses and the number of dead people could have been reduced by as much as 95% in Hiroshima, and by 60% in Izu Oshima. In addition, in Fukushima Prefecture, after 2011 Japan Earthquake and Tsunami disaster, the author contributed to the actual house relocation development in order to increase the value of reconstructed housing, avoiding the future disasters' risk through this Ecological planning simulations.
