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]
