La médina de Tunis de la vulnérabilité à la résilience

Abstract

The medina as a trace and witnesses of our past, are they able to have a present and a future by adapting? These vulnerable territories need to be resilient in order to overcome the risks to which they are exposed. These ancient fabrics, designed according to ancient logics, must adapt to modern mobility and technologies’ requirements; They must face new social logics and new governance’s ways. Competing with the new centralities, they face their own functional vulnerability. They have to adapt to the climate change’s vagaries and meet sustainability standards. Through empirical work, it studies the stakeholder’s system and the resilience of the medina of Tunis. The approach proposes to assess the resilience of the medina, as an urban fabric, social system, governance system, and architectural design, by studying the hazards the system faces and the forms of vulnerabilities it exhibits. The article demonstrates that the Tunis medina is a fabric that has shown adaptability to the risks and natural and anthropogenic hazards it has encountered - crises and socio-economic changes, heritage degradation, rural exodus, health crises - and especially its bioclimatic design makes it more resilient to new climate challenges. However, the study identified a set of physical, social, systemic, and organizational vulnerabilities that hinder resilience and the protection of human, economic, as well as architectural and urban heritage interests
