Assessment of land use changes and its impact on Agricultural soils in North Nile Delta region of Egypt using GIS and remote sensing

Abstract

E GYPT Nile Delta has very limited area of fertile soils which threatening by urban sprawl. Assessment of theurban areastretch effect on agricultural lands of the Egyptian Northern Nile Delta has been detected by using Landsat TM,Landsat ETM + and Landsat OLIsatellite images (1984, 2002, and 2016 respectively).Monitoring of urban sprawl was applied by visual interpretation viasupervised classification, on-screen digitizing and post classification change detection technique.The urban thematic layerand the land capability map using GISmade it possible to highlight the hazards of urban growth on the soils that have high capability. The obtained results showed that theoverallincrease of urban area amounted to 28 Km 2 .(210% of the urban area) during the study from1984 to 2016. The urban areagrowththroughout the 1984-2016 was on the expense of the soils that have good capability with amount of 18 km 2 (4 % of the good capability soil area).While the soils with fair capability lost 9 km 2 had 4 % of the fair capability soil area.The urban area growth over the noncapable soils (barren land) was very large during the 1984 and 2002period, where it has been amounted to 11 km 2 was converted to urban. The urban sprawlpattern has been changed during the period from 2002 to 2016, where very partial area amounted to(1km 2) of the noncapablesoils(barren land) was changed to urbanarea.It could be summarized that the urban sprawl represents one of themainsoil loss and degradation processesin theNile delta.

Classification and Mapping of Land Productivity, Capability and Suitability for Production Crops in West El-Minia Governorate, Egypt

“…Assessment of land evaluation depending on estimation of land performance for the specified purposes (FAO, 1976), and is considered as the basis for sustainable management of land resources to know quality of these resources are improved or degraded (Dumanski et al, 2010 andAbowaly et al, 2018). Utilizing of land evaluation mapping to give the information for the sustainable agricultural production, managing land recourses, land capability and land suitability of various kinds of land for specific land uses (FAO, 2008;Tadesse andNegese, 2020 andDebesa etal., 2020).…”

Land Evaluation and Assessment of Land Cover Change Using Geospatial Techniques: A Case Study in West Samlout Area, Egypt.

“…As a result, due to the vast library of regularly occurring, high-quality images with short intervals, remote sensing is currently a prominent tool for change detection research (Farrag & Mostafa, 2006). It is crucial for improved management to have timely and reliable information on LULC change detection of the earth's surface (Abowaly et al, 2018;Elzahaby et al, 2015). Agriculture constitutes an essential component of the societal structure and economy of Egypt, serving as the foundation for many sustainable development initiatives within the country.…”

Assessment of Land Suitability for Surface and Drip Irrigation Systems in the Northwestern Coast of Egypt.

“…Qualitative models derived from modification of soil landscape models are efficient means of interpolation point data based on conceptual relationship between observation of the soil property or condition being mapped and easily observable landscape features (Peterson et al 1996). Geographic Information System (GIS) used to query, link and retrieveboth of spatial attribute data (Abowaly et al 2018). This is in integration with the physical features can create a new data and predictive models that could be this is important for planners and decision makers (Ahmed et al, 1998).…”
