Temporal monitoring of land use/land cover change in Kahramanmaraş city

Abstract

Irregular urbanization causes problems such as decrease in fertile agricultural areas, irregular industrialization and urbanization. To provide a healthier life opportunity for future generations without disturbing nature, it is essential to determine the temporal changes in land use and to make land management plans accordingly. In this study, land use/land cover (LULC) change occurred in Kahramanmaras province within 30 years was investigated by remote sensing and integration of Geographic Information Systems. Landsat satellite images of 1988-1998-2008-2018 were obtained for the production of LULC maps. Each image was classified according to supervised classification approach using the support vector machines (SVMs) algorithms. The confusion matrix was created for each year to examine the accuracy of the LULC maps. The overall accuracy of the thematic maps was obtained as 91.76%, 93.56%, 86.89% and 88.29%, respectively. Also, Kappa values of thematic maps for each year were obtained as 0.88, 0.91, 0.81 and 0.84, respectively. When the results were examined, the development of industry in the city area and the construction of the airport contributed to the development of the social and economic structure of the city. The increase in the number of housing in the related regions has led to an increase in the amount of urban areas and a decrease in agricultural areas.

Comparative analysis of near-surface and surface urban heat islands in the Yangtze River Delta region

“…Climate change has led to an imbalanced distribution of water and heat, leading to a surge in extreme high-temperature occurrences in certain regions. Concurrently, as urbanization rapidly advances, urban spaces and their populations expand exponentially, accompanied by profound shifts in land-use patterns (Aliyazıcıoğlu et al, 2021;Topaloglu, 2022;Morsy and Hadi, 2022). These changes, by manipulating surface albedo and water evaporation, disrupt the equilibrium of surface heat budgets, encompassing both the sensible and latent heat exchanges between land and atmosphere, as well as vertical water vapor transport.…”
