As sudden changes in temperatures caused by global climate change in the Black Sea Region have adversely impacted hazelnut yields, climate scientist Professor Dr. Mehmet Levent Kurnaz made some statements on the importance of relocating the hazelnut plantations.
In recent years, hazelnuts have been affected by the presence of dangerous invading insect species. Additionally, global warming has led to frost events contributing to a reduction in hazelnut yields.
According to Kurnaz, the impact of frost on hazelnuts becomes noticeable at elevations below 700 meters, and according to observations, temperature variations are less significant at higher altitudes.
Kurnaz also expressed the possibility that a transition to alternative agricultural products may be necessary, similar to the majority of farmers in the northern provinces of Ordu and Giresun, regions characterized by intensive hazelnut cultivation, since "hazelnut yield is drastically declining."
