Apart from minerals and other natural resources, each inhabited territory on our ethnically varied earth boasts of a “rich” culture and history that can be used for sustainable development. In our modern world, particularly in the Western part of it this heritage or patrimony has come to play a crucial role in the development of spaces, most notably the rural ones by stimulating economic activity. However, so far patrimony in both its cultural and material aspects in Algeria has been the object of interest mostly from scholars interested in its preservation. The approach to cultural heritage is thus mostly anthropological and folkloric, and the final purpose of the so-called specialists in the field is to preserve for posterity a patrimony that they consider as being doomed to extinction by the modern way of life. Curators are assigned to keep watch over it in conservation spaces like museums and strangely enough whole geographical areas like the Berber zones on the fringes of urban areas. So to date little attention has been really paid to the crucial role that cultural heritage in all its aspects can play in developing the territorial attractiveness of rural or semi-rural areas by refining their cultural heritage instead of conserving it in the name of an immutable tradition or for official folkloric festivals. Taking our bearing from the socio-economic theory of sustainable development and a bottom-up approach to territorial development, and relying on interviews with female dressmakers, dress designers, associations working for the promotion of female economic activities, this research seeks to analyze and illustrate how a traditional dress festival of the Kabyle or Berber village community of Bouzegune in Tizi-Ouzou, central Algeria has boosted the economy of the region and tightened the sociological bonds. This case study analysis is centered primarily on the economic and social impact that the promotion of the Berber dress into a resource within the framework of sustainable development can have on the local population of Bouzguene in general and the female section of the Berber population in particular.
