Impacts of soil sealing on potential agriculture in Egypt using remote sensing and GIS techniques

摘要: This paper highlights the impacts of soil sealing on agricultural soils in Nile Delta using remote sensing and GIS. The current work focuses two aims. first aim is to evaluate productivity lost urban sprawl, which a significant cause Delta. second Land Use Cover Changes (LU LC) from 2001 2013 El-Gharbia governorate as case study. Three temporal data sets images different sensors: Landsat 7 Enhanced Thematic Mapper (ETM+) with 30 m resolution acquired 8 resolution, Egypt sat 2010 7.8 consequently were used. Four supervised classification techniques (Maximum Likelihood (ML), Minimum Distance, Neural Networks (NN); Support Vector Machine (SVM) applied monitor changes LULC investigated area. results showed that area are characterized by high depending its chemical physical properties. During 2010–2013, took place 1397 ha study classes ranging between I II. It expected sprawl will be increased 12.4% 2020 area, means additional 3400 productive agriculture. However, population growth most factor effecting
