Local Development II Urban Project: National Conference on the Environment of Lake Manzala -- October 27-29, 1991
The purpose of this report is to record, in an English language account, the proceedings of an important natonal conference (in Arabic) addressing a major ecological problem in Egypt. Lake Manzala, a large, shallow, saline water body adjacent to the 6ty of Port Said, has long been the recipient of vast quantities of untreated municipal sewage and industrial wastes flowing in daily from Cairo and other governorates. Eutrophication is the term commonly used when a water body, as a result ofa heavy input of nutrients (phosphates and nitrates), suffers from decreased dissolved oxygen and a profusion of algae, all of which dep,.Ic the fish population. The quanitities of sewage in Lake Manzala, however , are so large that hundreds of acres of this water body have effectively bete converted into a giant anaerobic lagoon. This, in turn, had an obvious adverse effect on the fishing industry which supports thousands of families living adjacent to the Lake.
