Utilization of geospatial information for recovery and rehabilitation from the northern Kyushu heavy rainfall disaster in July 2017

Unexpected torrential rains have occurred recently due to global warming. There is “limits of public help” in such a disaster. Therefore, “self-help” and “mutual help” become more important to protect lives. Improving these helps enhances disaster resilience. The purpose of this research is to propose initiatives utilizing geospatial information in recovery and rehabilitation phases and to indicate the effects of using geospatial information in the initiatives. The initiatives have conducted for rehabilitation in Toho village, which was damaged by the Northern Kyushu Heavy Rainfall Disaster in July 2017. One initiative is formulating a rehabilitation plan. Meetings are held to reflect residents’ opinions to the plan; using the map is useful to collect and share the opinions. Residents could discuss concrete future visions by using a map, and the rehabilitation plan reflected the opinions of residents could be published. The other initiative is Risk Communication. Many kinds of geospatial information are collected in it, and the Risk Map is published. The map shows the dangerous places and evacuation sites, and residents could understand their location, then the map enhanced disaster resilience.
