Widespread cocoa-driven clearance of forests in the Ivory Coast has led to farmers in the country moving across the border into neighbouring Liberia to create new cocoa plantations. Long one of the world's leading cocoa producers, Ivory Coast faces challenges such as ageing tree stocks and climate change that has led to declining production in the country. While farmers are leasing the land for these new plantations from Liberian landowners, the cocoa is being illegally trafficked back into the Ivory Coast and mixed in with Ivorian cocoa. This makes it exceedingly difficult to identify and trace source of cocoa being exported from the Ivory Coast, which could then violate environmental protection laws such as the European Union's regulation on deforestation free products.
