Abstract
: A series of heavy
rainfall, typhoon and earthquake disasters caused a proportionately large
number of deaths among the elderly in the year 2004 in Japan. In response to these tragedies, the national
government set up a series of committees to reduce damages and losses among the
disaster vulnerable population. The
discussions in the committee led to a new conceptualization that disaster
vulnerability was created due to lack of interaction between a person’s special
needs and the environment’s capacity/responsiveness in times of disaster. This paper demonstrated Kobe city’s Hyogo
ward project which involved a questionnaire survey and GIS mapping of people
with special needs (PSN) over various hazard layers. This helped identifying the highest risk
residents (approximately 155 individuals or 3.5% of the total populations of
4,400 PSNs in Hyogo ward) in terms of self-evacuation ability, social
isolation, building weakness and hazard exposures. GIS mapping of PSNs also helped practitioners
and community members to become aware of which areas have more concentration of
PSNs and thus more need for manpower mobilization in times of disaster. The paper concluded that community-based
multi-stakeholder collaborations along side with the “person-in-environment” model GIS
mapping were the key to reduce hazard vulnerabilities
among PSNs.
