Özet:

With the growth of cities, the land coverage and use changes in urban areas are also accelerating. Therefore, as a result of the occupation of the place by humans and activities in urban settlements with a dynamic and complex structure, problems such as excessive consumption of natural resources, environmental problems, unplanned and misuse of the land arise. In this study, the objective of the urbanization on the Mersin, Tarsus and Adana line, one of the united urban areas of Turkey, is to reveal the spatial change that occurs from 1989 to 2019 in the context of land coverage and use, to determine the spread direction of urban growth and to study the spatial dynamics that lead to this change/transition. For this purpose, accuracy analyses have been carried out by classifying 6 different Landsat satellite images provided to cover the last 30 years by a controlled classification method. As a result of the land cover/use maps produced, it has been shown that the cities in the work area often grow from the center to the surroundings and north, and also spread along the line on the Mersin-Adana road. In addition, in the 30-year period between 1989 and 2019, urban areas have doubled their existing area with an increase of 16,782 ha. The development of urban growth often on agricultural areas and semi-natural areas and the knowledge that these areas will be destroyed in the future, with the projects to be carried out forward, is the clearest indicator of spatial consumption.

Özet:

Changes in land covers and land use are increasing along with the growth of cities. Therefore, problems such as overconsumption and exploitation of natural resources, environmental pollution, and unplanned and improper use of the land because of occupation of the space by people and their activities in urban settlements, which have a dynamic and complex structure. This study aims to explore the urbanization line between Mersin, Tarsus, and Adana, which is one of Turkey’s conurbations, to reveal the spatial changes in the context of land cover and use from 1989 to 2019; determine the direction of urban sprawl; and investigate the spatial dynamics causing these changes and conversions. In this study, six different Landsat satellite images from the last 30 years were classified using a supervised classification method, and then accuracy assessments were carried out. The results revealed that urban areas have been growing from their centers to peripheries, mainly northwards and along the linear line on the Mersin-Adana highway. Additionally, the urban areas had doubled their existing area with an increase of 16.782 hectares in the 30-year period between 1989 and 2019. The urban areas have been sprawling on agricultural lands and seminatural areas, and current projects indicate that more such areas will be destroyed in the future. All these are clear indicators of spatial consumption in the study area. Keywords: Spatial change, Urban growth
