Our purpose is clear: to empower the humanitarian community to improve humanitarian response. We make this happen by supporting and championing the outcomes of robust research and proven innovations.

Mobile surveys have the potential to enhance food security information systems that have struggled to provide effective decision support. The mobile Vulnerability Analysis and Mapping (mVAM) project at the World Food Programme uses mobile technologies to collect food security information remotely. This paper documents use cases for mVAM (in camps, conflict, and vulnerable geographies) and assesses the tool’s contribution to decision-making. Managers have used mVAM to support advocacy and prioritise resources, but important obstacles remain before mobile surveys can transform information systems. mVAM and related initiatives should continue to build a rigorous evidence base and embrace open models of innovation.
