Purpose of the study was to define periodic cultivated and grassland areal changes between 1973 and 2015 with about 14-15 years periods. Three different socio-economic terms (1973-1987, 1987-2002, 2002-2015) were assessed in the study. In first term, rural population and urban population were in a balance in the region. In second term, immigration started from rural areas to urban areas because of security problems and industrial development and in third period, security problems decreased and people was adapted to the urban life in the region.  Landsat earth observation satellite dataset was used to be base material and end of July or August images were obtained for each research years. Object based classification technique was applied to extract cultivated lands and grasslands. According to the results, cultivated lands were increased around 130%, and grasslands were decreased around 8% in 43 years. Grasslands were only increase in first period about 18% due to animal husbandry was priority income in the region. However, rural areas were abandoned because of security problems and industrial development in western cities. So that animal husbandry was lost the importance in the region. People was started to do field agriculture instead of animal husbandry in second and third periods. Cultivated areas were increased around 38%, 37% and 22% in first, second and third periods respectively.
