Detection and monitoring land use/land cover (LULC) changes using historical multi-temporal remote sensing data is greatly important for providing an effective and robust assessment of the human-induced impacts on the environmental conditions. It is extremely recommended for LULC studies related to evaluating the sustainability of changing areas over time. The agricultural sector in Egypt is one of the crucial pillars of the national economy. The amount of traditional agricultural land (Old Lands) in the Nile Delta had a significant decline over the past few decades due to urban encroachment. Consequently, several land reclamation initiatives and policies have been adopted by the Egyptian government to expand agricultural land in desert areas (New Lands) adjacent to both fringes of the Nile delta. Tiba district is one of those newly reclaimed areas located in the western Nile Delta of Egypt with a total area of 125 km2. The primary objective of this article was to identify, monitor and quantify historical LULC changes in Tiba district using historical multi-temporal Landsat imageries for six different dates acquired from 1988 to 2018. The temporal and historical changes that occurred were identified using supervised maximum likelihood classification (MLC) approach. Three major LULC classes were distinguished and mapped: (1) Agricultural land; (2) barren land; and (3) urban land. In 1988, Tiba district was 100% barren land; however, during the 1990s, the governmental reclamation projects have led to significant changes in LULC. The produced LULC maps from performing the MLC demonstrated that Tiba district had experienced significant agricultural land expansion from 0% in 1988 to occupy 84% in 2018, whilst, barren land area has decreased from 100% in 1988 to occupy only 7% in 2018. This reflects the successful governmental initiatives for agricultural expansion in desert areas located in the western Nile Delta of Egypt. View Full-Text
