Tafilalet is a sustainable city in the desert and an interpretation of traditional and modern know-how. This is a very special human experience, with its social, urbanistic and ecological approaches. With quite noble objectives that translate into the reinterpretation of the urbanistic and architectural principles of the traditional Mozabit houses with the intention of giving true meaning to the notion of dialogue and mutual aid. A rich learning experience, Tafilalet obeys the requirements of sustainable development and is a model of bioclimatic construction, between the traditional and the modern, responding to the conveniences of modern life and is part of a social, economic, ecological and heritage perspective... The experience of Ksar Tafilelt, by its flexibility and its humanistic approach, can be generalized throughout the world, because good will and the spirit of sacrifice and social assistance exist everywhere: it is enough to locate them and to emphasize them.
