[email protected] Abstract The Dakar Metropolitan Area has urban problems caused by rapidly increasing population, illegal housing, traffic problem, flooding etc. Individual effort by responsible organizations has not yielded desired results bacause data preparation effort is duplicated among different organizations, their data collection by them are often mutually incompatible. It was desired to establish an information management system in the provision of social infrastructure utilizing GIS in order to support the development of urban facilities and services in the Dakar Metropolitan Area. JICA implemented the technical cooperation programs to establish a working system actually utilized by related organizations in Senegal through technology transfer. 1. Background evaluation and analysis of phenomenon in urban planning and The rate of population increase in the Dakar Metropolitan Area consider the potentiality of GIS application as a solution of urban (its population projection of 1999 was 1,900,000) is 4 percents issues. As a result of consideration, at first, it was designed both per year. The population density in the city is too high and the of a database and system, which structured information capacity for accommodating its population is too small to catch management system associated with infrastructure, and then up to develop infrastructure and maintain environment. As a established the system and a constitution of its management and consequence, random urban sprawl and deterioration of maintenance.
