The changing landscapes of BenghaziMansour ElbabourApril 18-19/2012

● Since the onset of urban planning projects in Libya in the mid-sixties of the last century, the city of Benghazi and its immediate surroundings have been undergoing phenomenal transformation that resulted in undesirable infringements on the natural environment. ● The site occupied by the modern city of Benghazi has been chosen to highlight urban and environmental peculiarities and transformations of a city deeply rooted in history for over two and a half millennia. ● Focus will be on the specific Karst lakes and Sebkha wetlands, which abound in the area, their environmental attributes, and their ultra-sensitivity.

● Current urban planning practices affecting the landscapes of Benghazi are investigated, and a reevaluation of the potentialities of its unique site calls for different development scenarios for the area that takes into account landscape ecology approaches, and the need to integrate nature into the urban scene of, perhaps, a long environmentally neglected city.

● It is argued that environmentally based planning strategies can preserve the fragile landscapes of Benghazi and, furthermore, ensure a more sustainable form of future urban development.

• A continuous belt of karst lakes and salt marshes defined the northeastern, eastern, southern, and southwestern limits of the old city.

• This elongated stretch of urban wetlands continues beyond the city limits in a north-easterly and southwesterly directions for tens of miles.

• Lakes and marshes are fed by an extensive system of underground channels, i.e., the legendary Lethe River and a group of surface karst lakes (Ain Zayana, Budezira, Maqarin, etc.)

• For most of the city’s long history, these extensive wetlands provided a valuable source of salt which was exported to other places.

• Wetlands served as effective natural defensive barriers for the city until the Italians built a defensive wall shortly after their occupation of the city.

• In addition to their cultural and scenic role, these urban wetlands also provided many valuable ecological and biodiversity services.

• Equally important, they served as natural flood control mechanisms and alleviated flood hazard during rainy seasons.

Wetlands space loss continues in the city of Benghazi!

• Despite their economic and environmental values, wetlands within, and around Benghazi are continuing to be modified and encroached

• Urban development and human activities in the city of Benghazi has resulted in the direct loss and alteration of a significant portion of its lakes and salt marsh wetlands.

• Half a century ago, the extensive central marsh of al-Salmani had disappeared completely.

• Now, a similar fate awaits another no less extensive and perhaps more ecologically sensitive natural habitat, i.e., Juliana Sebkha/Lake.

• The Juliana marsh/lake wetland, is a living example of an environmentally sensitive area currently under serious threat.

• Located in the northwest of Benghazi, it is roughly 4 km2. This makes it the largest remaining wetland located within the city limits of Benghazi and a reminiscent of the long, almost continuous stretch of marshes that once encircled the city since ancient times

• Since there has been little systematic effort to measure, document, and assess the condition of coastal and inland wetlands in Benghazi and its environs, such encroachments on the fragile ecosystems of wetlands will continue.
