Turkey provides 70 percent of the world’s hazelnuts, most of which are purchased by large manufacturers like Nestle and Nutella. Hazelnut harvesting is difficult and dangerous work, involving long hours on steep slopes in the sun. The work is undertaken by the poorest and most vulnerable populations, including migrants, women, and children, and many are refugees from Syria. Since 2017, WLP Turkey/KEDV has been working with seasonal agricultural workers in the hazelnut harvest to inform them about environmental threats to their employment security and safety, and to improve their working conditions through women’s collective leadership. One ongoing challenge has been to eliminate child labor. Another has been to address the warming waters of the Black Sea, which have triggered extreme weather events that have destroyed roads and bridges, and caused landslides that washed away thousands of tons of hazel harvests. Moreover, the higher ambient temperatures have disrupted the trees’ pollination cycles, reducing their yield. Also impacting the yield is the deterioration of the soil quality, hastened by the now more frequent droughts and erosion, which have also led to pest outbreaks.
