Swiss chocolate giant Barry Callebaut has broken ground at its first Center of Cocoa Excellence in west Africa.

The CHF1m (US$1.3bn) training and research centre, which will be operational from October, will be used to test “state-of-the-art intercropping approaches” and promote advanced agricultural techniques in Côte d’Ivoire, the world’s largest cocoa producing country.

The centre will include training facilities for farmers and a 30-hectare “showcase farm” that will test different approaches for growing cocoa with other crops.
