*3.3.1 Marmara region*

Based on the evaluation results of the 10 provinces within the Marmara region, it is predicted that, in general, the region will be adversely affected by climate changes in the upcoming years, which would decrease average sunflower yields. The increases in the number of days with maximum temperatures >35°C would adversely affect the plant pollination period during the sunflower vegetation period throughout the region, which would have a negative impact on yield.

*Possible Impacts of Climate Change on Sunflower Yield in Turkey*

The evaluation results within the seven provinces of the Central Anatolia region,

it is predicted that the yield in Konya and Aksaray, where there is intensive sunflower cultivation, would decrease; on the other hand, it is predicted there will be

The evaluation results for the five provinces within the Aegean region suggest that the region would be adversely affected by climate changes, which would decrease the average sunflower yields within the region. It is expected that the climate changes during the studied future periods would positively affect sunflower yield in two of the provinces (Aydın and Kütahya) and negatively affect the yield in

The evaluation results of the four provinces within the Black Sea region suggest that the region would be positively affected by climate changes, especially during 2041–2070 and 2071–2099; therefore, there would be an increase in average sunflower yield. During these periods, the expected increase in the average temperature and changes in the average relative humidity are predicted to contribute positively

Because of low number of provinces in the Mediterranean region in which sunflower was cultivated over the 30 years studied, the region could not be fully evaluated. Despite this, it is estimated that there will be increases in both provinces in the 2016–2040 period. In the second and third periods, excessive increases in both average temperatures and the number of days with daily maximum tempera-

ture >35°C are expected to adversely affect the sunflower yield.
