This document summarizes a presentation about harnessing volunteer technology communities to build crisis response capacity. It discusses how CrisisCommons convenes these communities across organizations to address humanitarian needs. It outlines how CrisisCamp events have engaged over 1,500 volunteers in 50 events across 10 countries. It also notes that while these efforts show promise, there remain needs for better coordination, infrastructure, resources and research. The presentation proposes that CrisisCommons could address these needs through initiatives like community projects, an incubator lab, expert council and research fellows program.
