“…As shown in Figure 8, the temporal and spatial variation in land cover is not homogeneous, with the density of buildings differing from one place to another. This is due to natural limitations such as water bodies (e.g., Lake Burullus) in the north of the study area, and consistent with observations in other parts of the North Nile Delta [18]. This observation should be taken into account by the relevant authorities in order to take the necessary measures to reduce the expansion of the urbanization of fertile land that is being driven by the increasing population in the region.…”

Soil sealing is currently one of the most critical barriers to sustainable development, particularly in developing countries such as Egypt. Agriculture is a major component of the Egyptian economy and the country’s main source of food security. Urbanization is devouring vast areas of agricultural land, and therefore, in the present study, urbanization was used to determine the degree of soil sealing in a region of Kafr El Sheikh Governorate, Egypt. In this work, remote sensing data were used to monitor changes in land use and land cover (LULC) between 1984 and 2016. A field survey and population data were also used in the analysis. Support vector machine (SVM) classification was used to produce LULC maps of the study area. An accuracy assessment was performed by calculating overall accuracy and individual kappa coefficients. Additionally, soil sealing was assessed using data from 1984 to 2016, and the potential expansion of soil sealing until 2048 was simulated using the cellular automata (CA)–Markov model. Our analysis showed that in the study area (i) about 90% of the soils had soil capability degrees between class II and class III; (ii) soil sealing was not uniformly distributed in the study area; (iii) between 1984 and 2016, the area of soil sealing in fertile soils due to urbanization increased by 19,500 hectares; and (iv) between 1984 and 2000, the urban area increased by around 29%, whereas between 2000 and 2010 it increased by around 43.6%. The results suggest that the magnitude of soil sealing is a good indicator of the soil loss rate and the potential for agricultural development in the Nile Delta. The model predicted that by 2048 an area of 32,290 hectares of agricultural soil will be lost to urbanization. This study indicates that the change of LULC has a negative impact on soil sealing. Between 2000 and 2010, the area of agricultural land decreased by 4%, despite an increase in land reclamation in the north of the study area. The amount of soil sealing was found to increase towards the southeast and northeast of the study area, except for the northern parts, where the amount of soil sealing increased towards the east. Our analyses and forecasts are useful for decision-makers responsible for soil-sealing mitigation strategies and soil-sealing protection plans in the Kafr El Sheikh Governorate, Egypt.

“…Therefore, by 2020 is expected about 20 percent will be consuming more than it has in Egypt. Water scarcity in Egypt could endanger the country and create instability [1][2][3] Estimating the volume of runoff in the northern regions of Egypt is considered one of the important things to explain how to take advantage of the lost water that causes many environmental hazards such as soil degradation, desertification and many environmental hazards [4][5][6][7][8][9].Surrounding factors such as terrain and climate are influence the rate of soil erosion, as the precipitation rate is the main factor determining the volume of runoff and the excess water moves from the surface towards the natural slope. Moreover, the runoff flow rate depends on several factors such as rainfall intensity, soil texture, infiltration rate, organic matter contents, vegetation cover, slope and aspect [10][11][12].…”

The sustainable agricultural development in the northwest coast of Egypt suffers constantly from the effects of surface runoff. Moreover, there is an urgent need by decision makers to know the effects of runoff. So the aim of this work is to integrate remote sensing and field data and the natural resource conservation service curve number model (NRCS-CN).using geographic information systems (GIS) for spatial evaluation of surface runoff .CN approach to assessment the effect of patio-temporal variations of different soil types as well as potential climate change impact on surface runoff. DEM was used to describe the effects of slope variables on water retention and surface runoff volumes. In addition the results reflects that the magnitude of surface runoff is associated with CN values using NRCS-CN model . The average of water retention ranging between 2.5 to 3.9m the results illustrated that the highest value of runoff is distinguished around the urban area and its surrounding where it ranged between 138 - 199 mm. The results show an increase in the amount of surface runoff to 199 mm when rainfall increases 200 mm / year. The north of the area may be exposed to erosion hazards more than the south and a change in the soil quality may occur in addition to the environmental imbalance in the region.

“…Agricultural sustainability aims also to enhance the agricultural means which control the input and output and reduce the pollution of food (El-Ramady et al, 2013). Sustainable agricultural differs from a region to another, as it is affected by the local environmental conditions of each country; sustainable agricultural in Egypt is effected by population intensity and urban encroachment as well as socio-economic conditions (Mohamed et al, 2018).There are several parameters used to evaluate sustainable agricultural such as soil productivity , socioand economic conditions beside soil sensitivity to erosion hazards by both water and wide (Dumanski, 1997). Moreover, the sustainable development is not easy to be evaluated where it is linked with numerous factors and needs an integration of socio-economic conditions with surrounding environment factors.…”

“…GOUDA (El-Nahry, 2001). Biophysics components such as soil productivity, soil erosion, socio-economic conditions and security are integrated together by GIS to evaluate sustainable agricultural in some areas in Egypt (Nawar, 2009 andMohamed et al, 2018). The same authors have identified the main obstacles to agricultural development in Egypt, like salinity and soil alkalinity, beside economic and social factors.…”

“…The expansion of agricultural development system is illustrated by Sharmaa et al (2006) and Matthews et al, 2008), who illustrated potential sustainable agricultural development in British Columbia. Recently remote sensing and GIS modeling have been used to clarify the probability of sustainable development where, the main aim of these models is the emulation of potential use of land in different screenplay beside the evaluation of environmental effects and soci-economic conditions (Mohamed et al, 2018).…”

S USTAINABLE agriculture aims at improving the production besides the conservation of natural resources. Egypt has a lot of sustainability obstacles facing agricultural development; some of them belong to soil characteristics such as soil salinity, soil type and others belong to environmental hazards and socio economic factors. The present study focuses on assessing sustainable agricultural status in west of the Nile delta by integration of physical, social and economic factors using GIS. The present study focused on five pillars for evaluating sustainability levels for agricultural development under Egyptian conditions; soil productivity, security, protection, social acceptability and economic feasibility in the different mapping units. The results showed that, the study area is classified into three classes: II, III, and IV which occupy an area of about 11.22, 64.92, and 12.08 % respectively. The results illustrate the current state of agricultural sustainability where, the values of sustainability varying between 0.1 and 0.36. About 48 % of the total study area is characterized by a very low degree of sustainability < 0.1 as it is classified as IV. This study proposed some recommendations to improve the current status of sustainable development such as increasing the number of markets, schools and health care, loan facilitation, and educating farmers modern methods of good management. The proposed recommendations will improve the sustainability degree by 10% of the study area.
