On a cocoa farm in Ghana, two chief executives sit on a log talking about their respective business goals. One is the CEO of Cadbury, Todd Stitzer; the other is the UK Director of the Fairtrade Foundation, Harriet Lamb. They are reflecting on the stories of farmers like Benjamin Atiemo in Adjeikrom village, whose children have left the village to seek work in the capital, Accra. Mr Atiemo's children, like those of many other farmers, are turning their back on cocoa farming. Apart from being hot and tiring work, yields from ageing cocoa trees are declining and, although international trade prices have surged recently, prices to farmers have scarcely kept pace with rocketing local food and fuel prices.
