Social media use is increasing rapidly across the world. There are currently over 800 million users on Facebook, over 175 million on Twitter, and over 4 million on LinkedIn. Many regions of the developing world have experienced a particularly acute rise in social media use. For example, recent statistics produced by indicate that the number of Facebook users in Somalia has increased by 131% over the past 6 months. This development is changing the dynamic of humanitarian crisis responses. During the 2010 Haiti earthquake, survivors trapped beneath fallen buildings used mobile technology to obtain assistance. The 2011 Arab Spring was fueled by discussions on Facebook and Twitter. And last month, the "Kony 2012" video was seen by millions of people within just 2 days, demonstrating the potential power of social media for humanitarian advocacy. But the humanitarian aid community is still in the early stages of learning about this technology. Meanwhile, social media users in humanitarian crises are engaging in policy discussions that are shaping local perceptions of humanitarian action. And increased engagement with social media by beneficiaries may challenge previously established institutional accountability mechanisms. To address these developments, the Program on Humanitarian Policy and Conflict Research (HPCR) at Harvard University is conducting a baseline survey to gather information about how the humanitarian community uses and perceives social media in its work. The results of this survey will be discussed at HPCR's upcoming live web seminar on May 10 and will inform HPCR's research agenda.
