This systematic evolution allows the uncontrolled urbanization to be managed. The continuous development of urban indicators and mapping methods are well used in the analysis of urban expansion ( Schwarz, 2010 Güneralp et al., 2020). In addition, among the most important conditioning factors of urban sprawl is the increase of population density a future increase of population density was expected. The main government objectives are to manage, support, and to regulate different sectors to afford the accessibility to services for residents and promote an adequate environment for private investment ( Shirazi and Falahat, 2012). The acquisition of human well-being and economic development requires urban transformations. Most of the future urban population and urban area expansion are forecast to take place in irrigated croplands, highlighting the potential competition for land between agricultural, coastal, and urban uses ( Catalán et al., 2008). Mediterranean coastal areas are among the most affected by an overall expanse of urban area. For this reason, the implementation of systematic strategies for urban monitoring requires citizen awareness, law enforcement, and scientific supervision to mitigate land consumption, reduce flooding vulnerability, and to control the environmental impacts of urbanization. This significant urban change in extent and structure during a short temporal scale could be considered as a serious issue. FRAGSTAT metrics described the change of landscape structure due to the increase of fragmentation pace, compactness degree, shape complexity, and proximity reduction. Analysis of parameters for urban sprawl quantification evaluated a sharp increase of urbanization rate, intensity, and dynamic degree. The results illustrated a dramatic increase of urban areas at the expense of agricultural land, maritime public domain (MPD) and hydraulic public domain (HPD). Based on Otsu binary maps, urban areas were quantified in two dates. Otsu segmentation showed higher accuracy than Edge segmentation method. We describe the changes in urban structures during the period of 2012–2016 by using Multi dates Pleiades images and using Otsu binary and sample-based Edge segmentation. The aim of this study is to quantify urban growth over lands in Kelibia city, a coastal region in Tunisia that is one of the most threatened Mediterranean regions. This expansion is frequently on most productive croplands and emerges as an important sustainability concern. In southern Mediterranean countries, coastal urbanization often occurs on croplands. 2Centre National de la Cartographie et de la Télédétection (CNCT), Tunis, TunisiaĬoastal cities are desirable places to live and work which results in ongoing and increasing urbanization.1Lr GREEN-TEAM (Lr17AGR01), National Agronomic Institute of Tunisia, Carthage University, Tunis, Tunisia.Zeineb Kassouk 1 * †, Hela Hammami 1 † and Haithem Ismail 2
