Using participatory methods to uncover interacting urban risks: a case study of three informal settlements in Phnom Penh, Cambodia

The residents of informal settlements face a diverse range of urban risks, from climate and economic shocks to local pollution and the threat of eviction. This article explores these risks by conducting Participatory Hazard Vulnerability and Capacity Assessments (PHVCA) in three informal settlements in the Cambodian capital of Phnom Penh. The assessment uncovers a variety of risks, which interact with each other and local vulnerabilities to produce complex risk profiles for residents. In this way, we highlight the importance of a holistic assessment of urban risk rather than focusing on single risks or specific sectors. The participatory approach also reveals household and community-level processes through which risks are experienced, negotiated and in some cases addressed, providing valuable insights into the ways vulnerable urban populations can be best supported.
