Abstract
Global warming and climate change processes are expected to raise sea levels.
This paper represents a contribution to the efforts of investigating the impact of
sea level rise (SLR) on the Nile delta coastal zone and identifies anticipatory and
adaptation measures that may be appropriate today in spite of current SLR
uncertainties. SLR was calculated by applying the quadratic equation for 10-year
intervals using 1980 as the base year. Despite large variation between SLR
predictions, the results indicated that SLR is accelerating, with estimated value
for the present (21st) century in the order of 0.6 m, although with a margin of as
much as ±0.4 m. Local land subsidence in the Nile delta would exacerbate the
impacts of rising seas. It was estimated that with a 1.0m SLR, about 4500 square
kilometers representing 19% of the delta area will be submerged and that
6.1 million people will be affected. These potential impacts of SLR would be
serious but manageable if appropriate actions are taken. The following
adaptation measures to the impact of SLR in the Nile delta coastal zone were
identified: maintaining and building coastal protection structures, restoration of
sand dunes along the shore, preserving existing wetlands, setting regulations to
control development in vulnerable areas, change of land use, relocation of
infrastructures in the landward side, and development of comprehensive
monitoring and early warning systems.
Keywords: sea level rise, coastal zone, impact assessment, adaptation, the Nile
delta.
