Johannes Baensch, Nestle's Head of Research and Development, and Ivory Coast's Prime Minister Daniel Kablan Duncan attend the inauguration of the Zambakro Nestle Experimental Station at a ceremony in Yamoussoukro, central Ivory Coast, December 11, 2013. Ivory Coast achieved record cocoa output in 2011, topping 1.5 million tonnes of beans, but many industry experts predict a gradual drop in production across West Africa as trees age and yields fall. Nestle, the world's biggest food group, said it will also grow 27 million coffee plants to help to revive the West African nation's coffee sector, which suffered falling output during a decade-long political crisis.
