Effects of Climate Change on Agriculture Production Under Rain-Fed Condition

Global warming has made a significant impact on water supplies. As a result of warmer climatic conditions, the acceleration of the hydrological cycle, climate change, an increase in precipitation and evapotranspiration (ET) now occur. In recent years, because of the development in industry, and the increased use of fossil fuels, there has been an increase in CO emissions, and in the temperature of the earth. The most significant changes observed also increase with higher temperatures during the summer months in Turkey. Furthermore, summer temperatures in Turkey’s Mediterranean and Southeast Anatolia regions are increasing. In addition, in the last 50 years the amount of precipitation during the winter season in the west of Turkey has significantly reduced. Climate change and the scarcity of rainfall limit agricultural production. In the southeastern region of Anatolia, in particular, agricultural production has been hampered by the droughts of 2008 and 2010. The average total of 30 years of rainfall was 344.1 mm in this semi-arid region. Between 1982–2011, the lowest rainfall measured 227.3 mm in 2008, while the highest measured 573.1 mm in 1996. In this study, we will focus on the many years of climate data on dry and under rain-fed conditions in the agricultural areas in the Southeast of Turkey.
