Protecting South Africa's macadamia nut crop

Macadamia nut farming is increasingly popular across the developing world and especially in Africa. Kenya and Malawi have sizeable plantations of the valuable nut and South Africa was the world's largest producer in 2015.

But the 2016 crop may be much lower because of the drought that continues to grip much of southern Africa.

Some analysts say that demand for the nut from China and the US remains strong, which will means prices will rise. But others say the fall in production threatens jobs.
