Volume 5 Article informations Towards a systemic approach to the development of the Nabeul coastline HAGUI A, Benslimene S. Abstract The purpose of this paper is to question a possible renewal of the temporalities of urban projects in Tunisia following the adoption of principles related to the exploitation of marshy areas. It is about understanding how to transform wetlands in the production and management of urban spaces. The importance of this text can be operated as follows: in the absence of a real will to apprehend the transformations of wet spaces on a rational basis forged by spatial equity, we try to present a new method based on the use of new tools (PLS SEM) in the definition of the organization of territories. Our approach is to use the lessons that have been learned from previous failures in order to format a new model based on a purely systemic approach. Key words: Planning, PLS SEM, coastline, collective intelligence
