Abstract |
: |
In the nearshore environment, near the places of human inhabitation there is a great chance of changes in the ecological factors due to the interference of man in the natural processes and changing the normal hydrographic conditions and disturbing the natural ecosystem by drastic effect on the benthic marine fauna both in the frequency distribution and species abundance.
Recently, Sharm Abhur becomes sector with potentially high impact for tourism. Large recreational centers, holiday villages and recreation facilities have been developed along the Sharm beaches without any adequate evaluation of potential environmental impacts. The construction of these large projects has required significant dredging and filling operations which adversely impact the coastal environment. In addition to the direct destruction of marine life and key habitats by dredging and filling, and other coastal construction and modification operations, the suspended fine materials resulting from these activities can result in widespread damage to marine life. Sedimentation from these operations results in the suffocation of the benthic communities and has an adverse effect on the surrounding
ecosystems (sea grass beds and coral reef). Furthermore, the seabed sediments form a sink for a number of pollutants; heavy metals and organic wastes due to input sewage and solid-waste disposal. Though, tourism could threaten the coral reef communities and other coastal habitats. . Excess effluent is dumped into the sea water causing eutrophication. Coral reefs are sensitive biological systems that are threatened by human activities and are therefore more threatened by high population density in coastal areas Coral reefs can also be damaged by development activities such as dredge and fill operation for port development and construction and operation of tourist resorts.
These impacts are causing extensive degradation to the coastal and marine habitats especially to coral reefs and benthic organisms.
Shortly, Sharm Abhur is considered as densely populated urban area due to the man made features, therefore troubling signs have come close to the point at which productivity falls and ecological functions collapse. Deterioration would cause significant losses of marine biodiversity and weaken the potential for long-term sustainable development. Information regarding effect of pollutants on benthic environment in Sharm Abhur has been interested. Environmental assessment can be one of the most important planning tools for meeting this goal. |
