City-countryside relationships are experiencing a revival in scientific research. Furthermore, the know-how inherent in cultural landscapes linked to water is of growing heritage interest to UNESCO. This global issue of living and intangible heritage arises for many community gardens and cultural landscapes in Algeria (Krystel in Oran, Beni-Snous in Tlemcen, Ain Madhi in Laghouat, etc.); community gardens shaped by hydraulic engineering form a series of landscapes combining nature and culture. Our article proposes to describe the economic, social and heritage vitality of the community gardens of Krystel in the wilaya of Oran, through an analysis of the different modes of water management, irrigation techniques, built cultural landscapes, but also the consequences of the evolution of social uses of space and the logic of appropriation; The notion of sustainability of these landscapes confronted with the logic of planning and development of the territories will be posed assiduously as well as the ultimate question of the valorization and heritage of these historic gardens as an exceptional universal heritage value, in a context of drift climate and energy scarcity.
