The Ahwash ritual of the Berber people of the Maghreb preserves an ancient cultural technique aiming at the reconstitution resp. actualization of the specifically human community with spirit and nature. With its over more than 2500 years continuing tradition It is still vividly practiced in some rather remote areas of the south-eastern Atlas regions. As an integral part of the project „The Atlas-Workshops of Agdz, Morocco“ in the framework of the new DAAD-program „Academic Dialogue with the Islamic World“ it can potentially be an important interface in regard of the implementary resp. participatory processes of the project. Within this wider context the Ahwash ritual could serve as a medium in search of common denotators of ‚sustainable developments’ between the different cultures.
