    Abstract

    The world Deltaic areas are sensitive ecosystem subjected to both natural hazards and human interventions, among which is the Nile Delta. During the last few decades, the northern part of the Nile Delta have been subjected to extensive unplanned development projects affected and accelerated hazardous changes over an important and highly populated area in Egypt. High spatial resolution Landsat and SPOT images representing the coastal desert along the central Nile Delta coast were used to provide information on coastal land uses changes of highly important economic value during the period 1984-2010. These types of land uses include wet lands, coastal sand dunes and coastal plain with the characteristic accreted ridges, in addition to agriculture, urban, reclamation, fish breading farms ( as an anthropogenic inputs). Results of processing the used satellite images demonstrate considerable growth of urban (2.8-19.0km2), fish farms (7.0-53.3km2), and areas of reclamations (17.7-132.2km2) on expense of wetlands (73.8-4.5km2), coastal plain (66.8—37.6km2), and coastal sand dunes (165.4-9.3km2). Agricultural land on the other hand shows considerable expansion from 93.5 to173.5 km2 during 1984 to-1997, then gradual decrease to 164.2, 149.1, and 147.5 km2 in 2003, 2006, and 2010 respectively. Among the anthropogenic hazard that threats the study area is the removal of dunes which represent a natural defence against coastal erosion and the continuous shrinkage and drying of the Burullus lagoon by about 48% of its total surface area. The low lands at the southern coast of the Burullus lagoon are areas vulnerable to sinking in case of sea level rise, and aggravated with the human activities of fish farms and water logging problem.
