The proposed research aims to assess the uses and consequences of communication technologies in the recovery and rehabilitation of populations affected by Typhoon Haiyan in the Philippines. Haiyan (known locally as Yolanda), which made landfall in the Philippines on November 8th 2013 was one of the strongest storms ever recorded with over 6000 casualties and more than 12 million people affected. In particular, we propose to investigate the uses of digital technologies and innovations such as mobile phones, SMS, crisis mapping and social media both by directly affected populations and humanitarian organisations. Communications technologies are increasingly recognized as vital in the prevention, mitigation and rehabilitation of disasters. It is even claimed that digital innovations such as social media are transforming humanitarianism by enabling 'people-centred humanitarian action' which empowers disaster-affected communities to coordinate and respond to their own problems. This optimism has given rise to a discourse on 'humanitarian technology' referring to the uses and applications of technology by disaster-prone communities in the response, recovery and rebuilding (World Disasters Report, 2013). Yet, despite the enthusiasm regarding the role of digital technologies as tools for humanitarian relief there is little evidence to assess their impact. What seems to be particularly missing from accounts on 'humanitarian technology' is the perspective of the affected populations themselves. Our ethnographic study aims to weigh the optimism surrounding 'humanitarian technology' against actual benefits to users. Our approach places the voice of affected people at the heart of the analysis. We will specifically examine the impact of communication technologies in the following critical areas: 1) information dissemination; 2) collective problem-solving; 3) redistribution of resources; 4) accountability and transparency of humanitarian efforts and, 5) voice and empowerment of affected populations. This is an 18-month ethnographic study that will take place in two disaster-affected locations (Tacloban, Leyte and Bantayan, Cebu) where we will conduct qualitative interviews, participant observation and online ethnography. We will conduct additional interviews with representatives from humanitarian organisations, government agencies and digital platforms to assess their uses of technological innovation in the disaster recovery efforts. Comparing the perspective of disaster-affected people and humanitarian organizations will allow us to understand both actual and potential uses of technology. The proposed research will be one of the first mixed method studies to combine an in-depth study of affected populations with a study of digital practitioners and humanitarian workers. The project will engage directly with humanitarian organizations, government and civil society agencies as well as the telecommunications and digital technology industry with which we have established partnerships. Our research aims to inform the academic, policy and public debates on the role of communication technologies in a humanitarian context.
