The Fourth ACM Symposium on Computing for Development (DEV-4) was held on December 6-7, 2013, at the University of Cape Town in Cape Town, South Africa. DEV-4 was co-located with ICTD, the 6th International Conference on Information and Communication Technologies and Development. In its fourth edition, the DEV conference continued its progress to becoming the premier venue for disseminating novel research at the overlap of technology and global development. In particular, it focused on highlighting research results in emerging region contexts where conventional computing solutions are often inappropriate due to many contextual factors---including, but not limited to cost, language, literacy, and the availability of power and bandwidth. Focusing on innovative technical solutions to these unique application, infrastructure and user challenges, the DEV-4 conference fostered exchange between computer scientists, engineers, and other scholars and practitioners interested in the use of information and communication technologies (ICTs) for development.
