As cash increasingly becomes an essential part of humanitarian assistance, it is critical that practitioners are aware of, and work to mitigate, exposure to protection risks among the most vulnerable recipients. This article presents findings from qualitative research exploring protection risks and barriers that arise in cash programming for internally displaced persons at high risk of violence and exploitation in Cameroon and Afghanistan. The authors conclude with recommendations for mainstreaming global protection principles into cash programmes, as well as key considerations for designing and implementing cash programmes in ways that minimize existing risks of harm and avoid creating new ones.
