Enfidha region is located in the center of Tunisia, marked by its landscape diversity, is subject to land use changes. Based on an interpretation of the 2007 and 2017 Landsat images, the dynamic of land use has been highlighted through a cartographic approach. The results show a significant decline in areas occupied by olive fields and cultivated land, a growth in built-up areas associated with an increase in grassland. However, land use mapping has also enabled us to highlight six types of landscapes, which indicate the diversity of the environments that occupy this area. As a result of demographic pressure and climate change, these landscape presents significant risks of degradation. This method could be useful for decision-makers in order to limit urban sprawl to the benefit of forests and olive groves and to implement a strategy for the protection of the Mediterranean coastline and wetlands.

Abstract
Enfidha region is located in the center of Tunisia, marked by its landscape diversity, is subject to land use changes. Based on an interpretation of the 2007 and 2017 Landsat images, the dynamic of land use has been highlighted through a cartographic approach. The results show a significant decline in areas occupied by olive fields and cultivated land, a growth in built-up areas associated with an increase in grassland. However, land use mapping has also enabled us to highlight six types of landscapes, which indicate the diversity of the environments that occupy this area. As a result of demographic pressure and climate change, these landscape presents significant risks of degradation. This method could be useful for decision-makers in order to limit urban sprawl to the benefit of forests and olive groves and to implement a strategy for the protection of the Mediterranean coastline and wetlands.

Abstract: (french)
La région de Enfidha au centre de la Tunisie marquée par sa diversité paysagère est sujette aux facteurs de changements d’états des milieux. A partir d'une interprétation des images Landsat de 2007 et 2017, la dynamique de l'occupation du sol a été mise en évidence à travers l'approche cartographique. Les résultats montrent une importante régression des surfaces occupées par les champs d’olivier et les terres cultivées, une croissance des zones bâtis associée à un progrès des surfaces de parcours. Toutefois, la cartographie d’occupation du sol nous a aussi permis de mettre en évidence six types de paysages ce qui montre la diversité des milieux qui occupent cette zone, qui suite à la pression démographique et aux changements climatiques elle présente d’importants risques de dégradation. Cette méthode pourra être utile pour les décideurs afin de limiter l’étalement urbain au profit des forêts et des oliveraies et de mettre une stratégie pour la protection du littoral et des zones humides méditerranéennes.
