This paper examines the design and evolution of a land-sharing process established for the on-site re-housing of an urban poor group in Phnom Penh (Cambodia), in the locality Borei Keila. The study is based on eight months of ethnographical and action research fieldwork. Some regard this land-sharing process as a success, but we find widespread criticism of it for excluding many original residents of the neighbourhood from the land-sharing agreement, leading either to their eviction or to difficult living conditions on site.
