Analyzing how big data can help countries swiftly analyze disaster impacts, mobilize resources, and implement recovery strategies, this brief considers governance and security challenges around the technology that can cut the cost of major events.
This paper argues that social media platforms present a significant potential of data sources to operationalize the provisions of the Sendai Framework.
This brief explores how new satellite imagery technology can help predict the impact of tropical cyclones in climate vulnerable countries such as Fiji, analyze their potential compounding effects, and improve disaster risk management.
This report aims to examine data on disaster losses related to infrastructure damage and service disruption in Post Disaster Needs Assessments (PDNAs) submitted by nations between 2010 and 2020, and to identify where gaps still exist in PDNA reporting.
