"This study forms part of the Humanitarian Policy Group (HPG)’s wider research on humanitarian ‘digital divides’. Drawing on existing literature, interviews with humanitarian practitioners and research with people affected by crisis in Venezuela and Uganda, it explores how the presence of social media in humanitarian crises intersects with efforts to make humanitarian aid more inclusive. It finds that, despite almost a decade of bold claims regarding the potential for social media to support humanitarian action, practical engagements among humanitarian actors are, for the most part, still on the starting block. Yet, given the steady expansion of internet access and smartphone use worldwide, social media is likely to play an increasingly prominent role for affected people in current and future crises. Consequently, it is not a phenomenon humanitarian actors can continue to side-step. Given the tendency of social media platforms to mirror and amplify existing dynamics of marginalisation, a specific focus on promoting inclusion will need to be at the heart of efforts to engage more deeply as part of fundamental humanitarian commitments to impartiality and to ‘do no harm’."
