In flood-prone areas of Viet Nam, most people are at high risk of drowning either because they can’t swim or lack information about how to protect themselves in the event of a flood. Children and women are particularly vulnerable – the latter because many of them commute to work by boat. Oxfam and the governments of Viet Nam and Australia have worked with affected communities to develop and implement a participatory disaster management programme with a systematic gender-aware approach. This paper describes the project.
