Abstract

In Egypt, urban sprawl accelerated rapidly in recent years, this phenomenon has various effects on economic and societal structures. Monitoring of urban sprawl faces many challenges, due to its random growing pattern. GIS is found to be a satisfactory method for monitoring and analyzing urban sprawl reasons. GIS facilitates prediction of future sprawl. This study aims to monitor urban sprawl against agriculture areas of Sharkia Governorate, Eastern Nile Delta, Egypt, and their effects, using multi-temporal Landsat images between years 2010 and 2013. Sharkia Governorate territory covers about 4911 km² with a population more than five million inhabitants. The Governorate cities expanded in all directions resulting in large-scale urban sprawl and changes in urban land use. Urbanization has many reasons; increasing population, absence of urban planning and weak establishment of new cities in desert regions. Cities having desert fringes extensions, are characterized by lowest urban sprawl hazard. The growth of urbanization often linked with existence of roads and canals which are generally provided with services of electricity, water and roads facilities. Continuing urban sprawl, at current rates may lead to disappearance of the cultivated at Sharkia Governorate within hundred years.
