Arid regions worldwide grapple with critical water scarcity challenges. Traditional water management systems, such as joussours, offer sustainable solutions rooted in local knowledge and ingenuity. This research delves into the potential of revitalizing joussours in the Toujen region of Tunisia, integrating them into contemporary landscape design. By analyzing the historical and ecological context of Toujen, we investigate the feasibility and benefits of restoring and enhancing joussour systems. The study focuses on the potential of joussours to improve water security, enhance biodiversity, and contribute to cultural heritage preservation. Through a combination of field research, design research, and community engagement, we aim to develop a holistic approach to joussour regeneration, combining traditional knowledge with contemporary landscape design principles. Key research activities include comprehensive site assessments, community engagement, innovative design development, technical feasibility analysis, digital solutions integration, and socio-economic impact assessment. The research findings will provide valuable insights into the sustainable development of arid regions and contribute to the global discourse on water conservation and cultural heritage preservation. By revitalizing joussours, we can create resilient and sustainable landscapes that address the challenges of water scarcity and climate change.
