摘要

The Old City of Ghadames (OCG), one of Libya's major desert cities and a world heritage site, played an important role as a cultural and trade center between the Mediterranean and Africa for over 1400 years. This role was enforced largely by the city's sustainability that was the product of highly developed desert environment engineering practices. The objective of this paper is to analyze these practices and demonstrate their effectiveness in light of the present challenges to the city's sustainability. The city's urban planning, architecture and adobe construction were perfect adaptations to social needs, religious values, resource limitations, harsh environmental conditions and remote location. Planning was conducted on the levels of the oasis, the city, the neighborhood, the street and finally, the individual house. Each of the city's 7 neighborhoods had its own properly located and sized public places. The 4-storey house design was based on human scale and needs. Buildings were connected "wall-to-wall" for insulation and maximum space utilization making the neighborhood one large building. The streets were covered to provide protection from heat, cold, wind, dust and rain with openings for light and ventilation. Effective protection against the harsh environmental conditions was also achieved through site selection, compactness, use of highly insulating building materials and routine maintenance. Water ― a precious commodity in the desert ― played a major role in the city's sustainability providing building materials and food. This role was effected through well-developed water resources management practices. The OCG was, thus, an outstanding example of sound engineering practices providing comfort, functionality and cost-effectiveness in a uniquely "Ghadamsi" architectural style and traditional construction materials and techniques; hence the well-deserved historic name "Jewel of the Desert". However, environmentally-induced aging and the interruption of routine maintenance have caused serious damages to many of its buildings forming a real threat to its sustainability and spurring efforts to conserve it with tangible results despite the unconventional challenges associated with such operations.
