The growing use of social media and other mass collaboration technologies is opening up new opportunities in disaster management efforts, but is also creating new challenges for policymakers looking to incorporate these tools into existing frameworks. The Commons Lab, part of the Science & Technology Innovation Program, hosted a September 2012 workshop bringing together emergency responders, crisis mappers, researchers, and software programmers to discuss issues surrounding the adoption of these new technologies. This report discusses the key findings, policy suggestions, and success stories that emerged during the workshop.
