The Voice of America (VOA) is planning two sets of 5 features on the Lost Crops of Africa. The first, created by VOA correspondent Cole Mallard is scheduled to air in about 4 weeks, according to information from Bill Eagle, another VOA correspondent who is working on the second set of features.
The first set includes: an overview; one feature each on fruits, vegetables and grains; and consideration of the future of Lost Crops.
I hope to post additional information closer to the actual broadcasts.
In 2006, VOA special English had a feature on Lost Crops.
