Climate, desertification and sustainability in the Sahara desert
Mohammed Sherzad
Ajman University, UAE
The transport and deposition of sand by wind are important factors which contribute to desertification process in the
Sahara desert. These regions contain more than 350 cities (Razavi, 1989). Sand encroachment and deposition in built
environments cause a number of problems such as erosion of building materials, and substantial coverage and often complete
burial of urban features such as buildings, transport facilities and roads, which then need continuous clearance and incur
continuing costs. In addition, the coverage of vegetation and agricultural lands has led residents in some areas to abandon their
houses or even entire settlements. This presents a complex problem to the architects as it demands attention not only to certain
aspects of building design but also planning the settlement as a whole. However, there is evidence that specific layouts and
building forms of some vernacular settlements in areas of active sand dunes, such as the region of Souf in the Algerian Sahara,
have survived and mitigated the impact of sand encroachment and deposition. The destructive effects of sand deposition are
more pronounced around contemporarily designed housing projects, which led many of them to be abandoned. The aims
of this research were to investigate the relationship between dwelling forms and the sand depositional geometrical patterns
formed around them, in particular around those located in areas of active sand dunes in hot arid lands, and to propose some
possible design indicators for building forms which may mitigate the undesirable features of sand deposition around them.
