    Two species of macadamia trees produce edible nuts, Macadamia integrifolia and Macadamia tetraphylla. Macadamia nuts are increasingly being recognized for their nutritional value. They also taste good and can be used in many recipes.

    Macadamia trees grow only in tropical climates. They need lots of rain and good soil. The tree is evergreen and bears a crop after 10 years. Macadamia trees will produce nuts for up to 100 years.

    Southern Africa is one of the biggest producers of macadamia nuts in the world. Other key producers include Australia, the USA, Brazil, Guatemala, Costa Rica, Malawi, Zimbabwe and Kenya.

     Farm Radio International has produced many scripts on trees and forestry. You can browse a selection here:

    You may be inspired to produce a program about tree crops.

    -Which tree crops are common in your broadcast area? Are fruit trees favoured? Are coffee, macadamia or cocoa grown?

    -Which crops are sold locally and which are exported? How is this decided? Can farmers easily access the different types of markets?

    -How do farmers feel about investing in tree crops which may not produce for a number of years? How do they deal with this time gap? What advice would tree-crop farmers give to others about planting tree crops?
