The climate is one of the most important factors for continuation of the life in the world and in thedistribution of life forms on earth. It also affects distribution and quality of natural and cultivated plants that'sgrown in the earth. Numerous studies carried out today shows that there is climate change. No doubt, thischange will be effective in many agricultural products as well as in poppy production. Poppy (Papaversomniferum L.), best known in human history, is an important industrial plants used for medicinal and oil. Inthis study, it is intended to determine effects of climate change in future on Turkey's poppy production thatis influential country on poppy production and opium alkaloids trade in the world. To this end, temperatureand precipitation data of climate parameters are used. Possible areas where poppy can begrown are shown depending on temperature, rainfall and topography. Temperature and precipitation aremodeled with topography; regions are selected for the temperature in range of 7-16°C and for precipitationin range of 300-1000 mm. Intersections of two layers, according to the long-term climatological parametersare determined as Poppy's life region. One of climate change models; HadGEM-2ES RCP8.5 scenario wereused to determine changes that may be occurred in the future. Using temperature and precipitationprojections for 2015-2040, 2040-2070 and 2070-2099 periods, possible changes are shown in poppycultivation areas for the future. As a result; it is contemplated that climate change would lead to a decreasein the production of poppy fields in the future and this work will contribute to the determination of thecultivation areas
