This case study explores perceptions of corruption amongst beneficiary populations, with the aim of informing strategies that seek to reduce corruption in humanitarian assistance. The study is divided into two main sections. The first gives a brief account of the context in which humanitarian assistance is delivered, outlining some of the corruption risks. It focuses on the response to renewed fighting and displacement in the north and east of the country since 2005 and the tsunami in late 2004. The second section explores perceptions of corruption voiced by beneficiaries during the research mission. These include irregularities in the registration process and in the distribution of relief, particularly of ‘bigticket’ items such as housing and boats, but also in politically sensitive processes such as the return of internally displaced persons.
