State of the art of greenway concept application in Tunisian green policy. A case study of an urban landscape in Sousse city

This paper is about the concept of the greenways in Tunisia, defined as a structure allowing to connect the green spaces between them. Two steps have been applied to assess the use of greenway concept in Tunisia and especially in Sousse city. The first one shows Tunisian administrative documents recount and the second one explains the spatial distribution of Sousse city greenways using GIS software. The examination of the planning of the green spaces in Tunisia, either through the documents of town planning or through the specific programs, allowed us to reveal the place of this notion in the Tunisian political speech and to conclude that the notion of greenways and its foundations, is missing in the documents of town planning, in the Tunisian environmental policy (Green Plan of Grand Sousse) even if the use of the term "greenways" is not really explicit. Then, it is our belief that there is a great potential in Tunisia for the adoption of greenways as a planning alternative, and tools such as the GIS environment can contribute significantly to this effort
