Investigating changes in land cover in high-density settlement areas by protected scenario

Abstract

Uncontrolled urban growth is one of the most prominent problems in modern urbanism and planning. Rapid urbanization and population growth cause changes in land cover. In addition, determining the effects of these changes is essential in terms of sustainable urban management policies. Urban growth is a complex, dynamic structure that initiates changes in land cover. For this reason, simulation models are used extensively in planning studies. In this study, land cover simulation of the Sancaktepe district in Istanbul was carried out with the SLEUTH model based on cellular automata (CA). The study aims to identify the damage caused by uncontrolled urbanization. In this context, a scenario was created based on the assumption that forests will be protected based on the changes in land cover that occurred between 1961-2014. The data used in the model were generated from cadastral maps on a parcel basis. For this purpose, four-period data sets (1961-1992-2001-2014) were prepared between 1961-2014. According to the simulation results, 82% of agricultural land, 2% of forest land and 84% of open land will probably be converted into residential use. According to the results, it has been determined that almost all of the open and agricultural land in the towns of Pasakoy and Samandira in the district of Sancaktepe have been converted into residential areas. According to the prediction that the changes in current land cover will continue, no change is expected in forests, while it has been determined that the potential to transform agricultural land and open land into settlement areas is quite high.

Spatio-Temporal Evolution and Driving Mechanism of Urbanization in Small Cities: Case Study from Guangxi

“…Canaz Sevgen [100] analyzed the change of land urbanization in Turkey based on random forest and Airborne Lidar Data in an attempt to improve the reliability of spatial classification results of complex urban areas. Yakup [101] simulated the land use and cover changes in Istanbul with the metacellular automata model to analyze the damage caused by urbanization.…”

“…Kaçak ve imara aykırı yapılaşma sonucu oluşan kontrolsüz kentsel büyüme modern şehircilik ve planlamanın en önemli sorunlarından biridir (Yakup & Ayazlı, 2021). Bunun yanında kaçak yapılaşmanın oluşturduğu ortamın doğrudan ve dolaylı olarak meydana getirdiği sorunlar vardır (Ekici & Tuncel, 2015).…”

The plight of urban settlements based on the proliferation of dichotomy in Tanzania

“…Many countries in Sub-Saharan Africa are still undergoing land reforms since independence and they are still experiencing the juxtaposition of informal and formal settlement [15,16]. The informal settlements are prevalent to the extent that about half and three-quarters of all newly constructed houses in African cities have been developed in un-serviced and unplanned lands without having formal land administration and legal compliance, land use planning, construction permits, and transfer of ownership right [17,18,19,59,60]. For example, only 15% of the population in Tanzania is living in a well-serviced and well-planned formal settlement only [20,21].…”

“…Consequently, the flourishing of dichotomy urban settlements in fastgrowing cities which are exorbitant and unmanageable towards efforts of ensuring sustainable urban land development. Analysis of land use and land cover change offers useful results for determining and implementing land management policies [24,25].…”
