Abstract

The international disasters database (United Nations Office for Disaster Risk Reduction "UNISDR"/the Emergency Events Database "EM-DAT") estimated the number of people affected by natural disasters in 2018 to be 61,772,617. According to (1), approximately 15% of the global population comprises people with disabilities. Despite being the most vulnerable group during emergencies and disasters, people with disabilities tend to be ignored in risk mitigation efforts, making it vital that solutions be developed for them within the framework of international conventions. Efforts to identify the area and population affected during a disaster are important aspects of disaster management. Prior identification of danger zones and segments of society who would be at the greatest risk in the event of a disaster could be considered as the first step in damage mitigation and disaster impact reduction. This study investigated the issue of accessibility among individuals with special needs during a disaster using a geographic information system (GIS)-based approach. In this study, addresses of individuals with disabilities in Eskişehir were collected along with their geographic location coordinates (latitude and longitude), and the data were compiled into a database along with other attributes. GIS analysis techniques were used to store, query, and analyze the data. Using GIS and network analysis methods, the fastest routes to emergency assembly points were identified for individuals with intellectual, physical, hearing, or visual disabilities. The service area network analysis method was used to establish accessible routes on the road network that would allow the focus population group to reach disaster assembly points in the shortest time. The number of individuals with disabilities in these areas and their locations were identified to aid the analysis. Digital maps were created to interpret the results.

Early intervention to risk groups with the QR code system in disasters

“…To give an example, after the Great East Japan earthquake of 2011, it has been proven because of the research that the disaster-related death rate of disabled people is 4 times higher when compared to other members of the society. After the tsunami that occurred due to the 2004 Indian Ocean earthquake, it was determined that 700 people with physical disabilities lost their lives in the Andomon Islands because they could not evacuate to high and safe areas (Tün et al, 2019). In a study conducted by Buluş Kırıkkaya and Gerdan (2018), the problems faced by the disabled people were examined, and while the participants of 30 people stated that they were prepared for disaster and had an idea under normal conditions, they showed that they did not have a clear idea when they were disabled or have a disabled relative.…”

Using of GIS on field geology studies; An application on central-southern of Eskişehir

“…Kumsar et al (2011) contributed to the control of urban development developing a geological and geotechnical urban information system in the GIS environment for Denizli province center. Tün et al (2015) developed disaster management practices by interpreting earthquake data obtained from seismic networks in GIS environment. In this study, it is aimed to present new findings to the stratigraphy and neotectonic evolution of Eskişehir region by using GIS and field geology studies in an integrated manner.…”
