    Urban sprawl is threatening the limited highly fertile land in the Nile delta of Egypt. Landsat TM satellite images of 1984, 1992 and ETM+ of 2006 have been used to study the impact of urban sprawl on agricultural land of the Northern Nile delta, Egypt. Visual interpretation using on screen digitizing and change detection techniques were applied for monitoring the urban sprawl. Combining the land capability map and the urban thematic layer using GIS made it possible to point out the risk of urban expansion on the expense of the highly capable soil class.

    Waterlogged and salt-affected soils are serious environmental hazard indicators for wasteland problems in arid and semi-arid regions of the World. Similarly human activities in agricultural and urban sustainable developments have also led to the development of waterlogging and subsequent salinization of soils leading to many geo-environmental problems. Thus, it is important to be able to monitor, assess and map waterlogged and salt-affected areas at an early stage to develop an effective soil reclamation programme that helps to reduce and prevent a future increase in areas of wasteland.
