The plateau of Yagour is one of the high places of the cultural and natural heritage of the northern watershed of the Toubkal massif in Morocco. Through his inheritances, he attests to a long adaptation of the Man to his environment. Indeed, since the prehistory, the residents of the Yagour have adopted agro-pastoralism as a way of life. Through their ancestral know-how, they maintain a symbiosis between two productive systems, namely agriculture (vegetable, cereal and fruit), and extensive livestock farming. Common property shared and managed by rights holders from neighboring valleys, the Yagour constitutes a resource of reserve and survival during the dry season. The villagers’ then transhumate in the summer pastures of the Yagour which they have commonly reserved for natural regeneration from the beginning of spring to the beginning of summer. In addition to this management system locally called “Agdal”, the Yagour is full of heritage treasures including rock carvings dating back more than 2000 years before our era for the oldest. These trace the history and evolution of the predecessors of the mountain people around the Yagour. Today, this place of sacredness and ancestral culture undergoes various socio-spatial changes that constrain the perpetuity of its inheritances and landscapes. The development of the accessibility of the Yagour favors the mobility of riparian populations and, of course, tourists. Straddling between the valley of mass tourism of “Ourika” and the valley barely touristic of the “Zat”, the Yagour plateau should in the near future face the challenges of the tourism industry. In the face of such an upheaval and in order to ensure the sustainability and promotion of the various heritage resources, this article will first examine the changes and developments in the different production systems, their trends of convergence or divergence, and the resulting synergies and competitions. In a second phase, we will discuss the potential and the challenges that tourism could bring to this territory, its heritage and the people who live there. Finally, we will examine the role of mediation between actors, in their nested and hierarchical system, in order to face the new stakes of this territory, as well as the role of tourism as a facilitator of this mediation.
