BIG DATA AND DISASTER MANAGEMENT

Aug. 25, 2019

According to a report by the U.N.’s Asia-Pacific social agency (UNESCAP), use of big data can better predict increasingly complex disasters in the Asia-Pacific region.

Key findings of report:

Since 1970, natural disasters in the Asia-Pacific region have killed two million people — 59% of the global death toll for that period.
Disasters also cause more damage in Asia and the Pacific, measured as a percentage of GDP, than the rest of the world, and this gap has been widening.
However, big data innovations reveal patterns of complex disaster risks which helps to understand and predict the risk of extreme and slow-onset events.
Flood and cyclone forecasting now relies on computer simulations. Sensor webs and the Internet of Things have enabled efficient earthquake early-warning systems. Remote sensing via satellites and drones provide quick assessments of damage and people affected, and help in relief efforts.

Big Data?

Big data refers to the analysis of very large data sets to reveal patterns, trends and associations.
The data can come from a range of sources, including satellite imagery, drone videos, simulations, crowdsourcing, social media and global positioning systems.
