摘要：Hazardous land is given high profile in the Tanzanian National Land Policy 1995. Subsequent land laws provide for participatory procedures to declare land to be hazardous. Public authorities have over the years been concerned about the continued living on a flood-prone Msimbazi River Valley in the city of Dar es Salaam. Despite adopting carrot policies such as allocating alternative land, and stick policies including forced eviction and demolition, sections of the population have continued to live in the Valley. Research on the ways public authorities have dealt with flood-prone areas, established that legal procedures to declare Msimbazi River Valley to be hazardous or environmentally sensitive have never been taken, and are not well-known among officials. Moreover, focus has been placed on valley dwellers instead of addressing citywide flooding. Paternalism, dealing with market failure and exerting political authority are considered to be the drivers motivating the government to evict valley dwellers. It is concluded that the approach dealing with dwellers of floodprone areas should adhere to legal provisions by, in particular, being participatory; should utilize available technology to identify, declare and demarcate hazardous land, should put this land to the badly needed greening of the city; and should address citywide flooding as a part of managing the city instead of focusing on a few individuals in a particular hazardous area.
