The causes of forest fires in Turkey can be grouped under four main groups such as arson (intentional), carelessness and negligence, natural and unknown fires. Especially the Mediterranean and Aegean regions are the places most affected by these fires. According to the data obtained from the General Directorate of Forestry (OGM), between 1988 and 2019, 4.91 ha forest area was burned per fire only in Hatay. Especially satellite technologies developed in recent years and Remote Sensing (UA) techniques are widely used in the detection of forest fires. In this study, fire severity maps were produced on the Google Earth Engine Platform (GEE) by using the UA method for the forest fire that broke out in the Belen district of Hatay on 09.10.2020. For this purpose, Sentinel-2A (L2A) satellite images dated 04.07.2020 before the fire and 12.10.2020 after the fire were used. The burning severity was graded using the Normalized Differenced Vegetation Index (NDVI), Normalized Burned Ratio (NBR) and NBR differences, Difference Normalized Burned Ratio (dNBR). In addition, elevation, slope, and aspect maps were produced with Geographical Information Systems (GIS) and forest fire was analysed in terms of topographic factors. High burning severity was observed in 50 ha area where the altitude was between 200 - 300 m, in 36 ha area where the slope is more than 30% and in 35 ha area in the eastward. As a result of the analysis, the area with high burning severity in the study area has been calculated as 90.94 ha in total. [ABSTRACT FROM AUTHOR]

In previous years, as a result of wind erosion in the Manisa-Akselendi plain in Gediz basin, sand dunes have occurred. At the same time, major environmental damage has emerged because of improper agricultural practices on the area. The areas where the wind erodes and accumulates cover a large portion of the plain. The study was carried out in Manisa-Akselendi plain to investigate the temporal changes in vegetation using landsat satellite images of 1985, 2005 and 2017. Normalized Difference Vegetation Index (NDVI) maps of the area were prepared for these years. According to research that the bare rock, sand and non-plant areas of the study area were 44.66% in 1985, this figure halved in 2005, decreased to 0.58% in 2017. Vegetation areas (NDVI values between 0.1 and 0.5) of the research area were 122.47 km² in 1985, then increased to 193.34 km² in 2017. Except for the reforested areas, the expansion of intensive drip irrigation agricultural activities in the sand dunes has also had an important effect on these changes. [ABSTRACT FROM AUTHOR]
