Big data and technology in disasters: Better integration needed for effective response

Aug. 23, 2018

In a recent review article published in the journal Disaster Medicine and Public Health Preparedness, a group of Johns Hopkins’ authors evaluated 113 studies using predetermined criteria with the final search taking place on May 1, 2017. Search terms were created in consultation with medical librarians and subject matter experts in Information and Communications Technology (ICT), big data, and disasters. Only articles that implemented ICT and big data tools in real life were considered.

A data extraction tool was developed by subject matter and included the following items; first author and year, data type, disaster type, country.

The literature review identified some important gaps: More information is needed on the use of technologies. Most articles discussed the use of ICT in natural disasters which were mainly hurricanes and earthquakes. What was underreported was data on extreme temperatures and flooding, even though these events account for 27% and 26% of global deaths respectively.

According to first author Dr. Jeffrey Freeman, “Disasters are inherently a Big Data challenge, and with the ubiquitous nature of cell phones, the rapid spread of connectivity, and the rise of technologies like the Internet of Things, the challenge is only going to get bigger. In disasters, the key question we face today is, ‘How do we harness a growingly diverse and often chaotic wave of data and information?’ Simply put, we’ve got to handle more data than we’ve ever had, and do so more quickly and effectively than we’ve ever done before. Big Data and ICT pose a serious challenge in disasters, but they also hold promise for potential solutions. The answer to leveraging the massive amounts of data that ICT is creating is likely to be found within the very same technologies driving the information age. But we have to think creatively about adapting and adopting these technologies in emergency situations. Disasters leave little room for trial and error. The consequences are too great.”
