“…Remote sensing (RS) and geographic information systems (GIS) have long been used effectively for the determination of changes in LULC [31,38,39] with a combination of the required survey data and land information. Studies using satellite images to monitor LULC changes are varied in their aims and scopes like forested areas [40], water supply [41] and plant cover [42]. Different types of approaches are used to determine the changes in LULC and to identify the spatial differences in LULC patterns considering both temporal socio-economic and surface characteristics data [17,30,43].…”

Tourism contributes to national and local economies especially in the Mediterranean and Aegean coasts of Turkey including the study area, Fethiye-Göcek, Muğla in southwest Turkey. The study evaluates land use/land cover (LULC) changes driven by tourism development as a case considering the past (1995–2020) and future environmental impacts on the area. High-resolution remote sensing and some socio-economic data were employed to monitor the situation and causes of LULC changes using Normalised Difference Vegetation Index (NDVI) and Land Surface Temperature (LST). The results show a decrease in the size of water surface, forest and maquis lands due to tourism development together with an increase in urban fabrics and bare lands due to urbanisation and forest fires. A significant positive correlation was detected between the urbanisation rate, population size and built-up area as well as air temperature and LST. Rapid and unplanned tourism development boosted investments for infrastructure and facilities and thus increased the demands for lands. Such lands were mostly gained by filling the sea or transforming agricultural and greenhouse areas, forest and maquis-covered lands. The unplanned development of tourism and urban areas caused serious hazards to the natural and cultural areas which threaten the sustainability of tourism. Planning suggestions are proposed to decision makers like coordination works for sustainable and responsible tourism development.

“…There are many studies that determine LULC with opensource Landsat images effect on forest cover (Yavaşlı, Masek, & Franks, 2013), water resources (Cüceloğlu, Şeker, & Tanık, 2021), vegetation (İkiel & Koç, 2015), geomorphology (Ölgen, 2004) and soil salinity (Aksoy, Yıldırım, & Gorji, 2022). In recent years, there are a lot of studies in which Object-based classification is used in determining the LULC (Sertel & Akay, 2015;Alganci, Sertel, & Kaya 2018;Esetlili, Bektas Balcik, & Balik Sanli, 2018;Karabulut, Ceylan, & Bahar, 2021).…”

Bodrum Peninsula is one of the most important tourism centers of Turkey with its geographical location, coastal and marine tourism, natural and cultural features. It has been determined that the winter population has also increased in Bodrum in recent years, and it is thought that this may cause an increasing permanent resident population and urbanization. The objective of this study is to determine the changes in land cover due to the rapid increase in urbanization in Bodrum Peninsula. For this purpose, object-based classification analysis was applied to Landsat 4-5 TM 1990, 2000, 2010 and Landsat 8 OLI 2021 multispectral satellite images. Within the scope of the analysis, the objects were created by applying the segmentation process to satellite images. Secondly, land cover classes were determined according to the Corine land cover classification with levels 1-2-3. Thirdly, the classification process based on a decision tree was carried out with the classes defined using the threshold values determined for spectral and texture properties of the objects using multiresolution segmentation. In the last stage, accuracy assessment analysis was applied to the classification results. According to the results, it is obtained that while Urban Fabric and Burnt Areas are increased in 32 years, Forest and semi-natural areas are decreased. As a result of population pressure due to tourism, Urban Fabric areas have moved closer to Forests and Semi-Natural Areas. Wildfires with the effect of heatwaves were increased, biodiversity has been endangered in the study area located in the Mediterranean basin, where human-related climate change is most clearly detected. Significantly, there has been a wildfire in Bodrum in August 2021, which lasted for days and caused severe degradation on the land cover. For this, sustainable land cover management is recommended to protect the natural ecosystem by minimizing the risks that cause land degradation in the Bodrum peninsula.

Changes in the coastline of the mouth area of the Sakarya River (one of the large Turkey Rivers, flowing into the Black Sea) due to the relative imbalance of the processes of water and sediment flow of the river, on the one hand, and processes of coastal erosion by sea currents and waves, on the other, that is especially characteristic for the south and east the Black Sea coast. are revealed. For this, Landsat 4, 5 and 8 satellite images for the period 1985-2018 were used, as well as Google Earth cartographic service. Within the study area about 40 hectares of coastal land were destroyed for this time. And in the mouth area itself, the area of wetlands decreased by 100 hectares due to a decrease in the inflow of river water, as well as intensive economic and recreational activity. Due to the peculiarities of the water masses circulation in the sea, the western part of the coast at the mouth of the Sakarya river more eroded. And the eastern part in recent decades has been actively protected from erosion by special structures, infrastructure and port facilities. To analyze satellite images, we used the ERDAS imagine program, the isodata algorithm.
