Improving the building permit administration process in cities in developing countries The Case of Yaounde (Cameroon)

The habitat in the cities of developing countries is facing serious dysfunctions. The lack of respect of the regulation as regards of town planning, often involves the anarchistic occupation of the urban space in particular in the areas of spontaneous habitat. In this article, we propose a decision aid system, which could contribute to the improvement of the process of regularization of the permit building. The main point of our studies is laid on the interactions with the existing tools of storage and treatment. Three types of interactions: 1) the functionalities of the data base management system; 2) the queries from the data base; 3) the presentation of the results of the instruction. In view of the processes and the tools proposed, the town planners and managers could start a reorganisation of the spontaneous habitat while increasing the royalties.
