Type of territory

M'Zab valley is a universal heritage, classified by UNESCO (1982), with its ksourien planning (pyramid shape) and its Oasis hardly formed in an arid environment. Since about two decades Algeria has a deep housing crisis across the country, due to population growth. Moreover, the Mzab is a region in southern Algeria which has a Muslim population practicing Ibadi sect in general. One that refers strictly to the holy book, the Qur'an, and the Sunnah, as is also characterized as much by the tolerant appearance dictated by God by solidarity between people. Add to this a number of social practices by Ibadites Mzab and social organization of pyramidal type that fall under all of the precepts of Islam. Thus, a set of families (different surnames) gathers in a large family, "Achira". They find themselves in a "Arch" and within the religious structure, known as "El Halquat Azaba" that guide spiritually, directs and advises socially.
