“…This area supported the settlement, the prosperity and the expansion of one of the oldest and greatest civilizations in world history [2,34]. The Nile Delta is located in the north of Egypt and stretches from Alexandria governorate in the west to Port Said governorate in the east [35]. The study area ( Figure 1) consists of 12 administrative divisions (governorates).…”

Dramatic Loss of Agricultural Land Due to Urban Expansion Threatens Food Security in the Nile Delta, Egypt

Egypt has one of the largest and fastest growing populations in the world. However, nearly 96% of the total land area is uninhabited desert and 96% of the population is concentrated around the River Nile valley and the Delta. This unbalanced distribution and dramatically rising population have caused severe socio-economic problems. In this research, 24 land use/land cover (LULC) maps from 1992 to 2015 were used to monitor LULC changes in the Nile Delta and quantify the rates and types of LULC transitions. The results show that 74,600 hectares of fertile agricultural land in the Nile Delta (Old Lands) was lost to urban expansion over the 24 year period at an average rate of 3,108 ha year-1, whilst 206,100 hectares of bare land was converted to agricultural land (New Lands) at an average rate of 8,588 ha year-1. A Cellular Automata-Markov (CA-Markov) integrated model was used to simulate future alternative LULC change scenarios. Under a Business as Usual scenario, 87,000 hectares of land transitioned from agricultural land to urban areas by 2030, posing a threat to the agricultural sector sustainability and food security in Egypt. Three alternative future scenarios were developed to promote urban development elsewhere, hence, with potential to preserve the fertile soils of the Nile Delta. A scenario which permitted urban expansion into the desert only preserved the largest amount of agricultural land in the Nile Delta. However, a scenario that encouraged urban expansion into the desert and adjacent to areas of existing high population density resulted in almost the same area of agricultural land being preserved. The alternative future scenarios are valuable for supporting policy development and planning decisions in Egypt and demonstrating that continued urban development is possible while minimising the threats to environmental sustainability and national food security.

“…Coupled with unplanned developmental activities, this has resulted in the growth of many new urban areas that lack adequate infrastructure facilities [9]. Determining the trend and the rate of urbanization is vital to the establishment of rational land use policies [10].…”

Abstract-Urban growth is very dynamic and complex processes, It has many factors affects on the directions and value of urban extensions, the factors that drive urban development must be identified and analyzed, The study of relative research shows that the driving forces which lead and redirect the urban sprawl, and try to classified these driving forces based on the value of its effectives on urban growth, Achieving the classification of driving forces needs using statistical method, our study used the logistic regressions to analysis and classes the driving forces for urban sprawl, Identifying the driving forces is the most important step to prediction the urban growth in future by using the cellular automata models so that the research try to prepare this step to complete the procedure to expect the urban extensions, This study takes Aswan area as a case study in period from 2001 to 2013 by analysis the official detailed plan and google earth historical imagery, Almost data prepared to logistic regressions analysis using ArcGIS software and IDRISI®Selva. We studied historical imagery of the area using Google Earth to examine changes in urban growth in 2001 and 2013, over a span of 12 years. The results showed urbanization in risk areas to be 59.79 % in 2001, then rising to 65.45 % in 2013, by the end of this paper it can be classified the effect of the driving forces in study area.

“…According to Shalaby and Moghanm (2015), with the exception of western and eastern desert fringes and areas along the coast, soils within the Nile Delta can be classified as Entisols (Vertic Torrifluvents). As determined by combining images from four satellites (Fujihira 2014), the area containing the same soil type corresponds to the distribution of croplands within the Nile Delta.…”

Eddy correlation measurements within the Nile Delta allowed the determination of evapotranspiration (E) for seven crops (rice, maize, cotton, sugar beets, berseem, wheat, and faba beans) using basin irrigation (BI), furrow irrigation (FI), BI with increased intervals (BIi), FI with increased intervals (FIi), strip irrigation (SI), and drip irrigation (DI). Total E values over the cropping season for rice (BI, BIi) were the highest (>600 mm) while those for sugar beets (DI), maize (SI and DI), and berseem (BIi) were the lowest (<250 mm). Differences were due to a combination of atmospheric demand, soil moisture, the presence of surface standing water, root depth, and the length and timing of the cropping season. The DI and SI methods had an advantage for water saving, while the FIi and BIi methods were effective for crops with shallow root lengths. Estimated annual E was 566-828 mm/year (water-saving irrigation) and 875-1225 mm/year (conventional irrigation).
