In 1980, Lesotho produced 80% of the cereals it consumed. Now it imports 70%. The only real cash crop is marijuana, grown between rows of maize and smuggled to South Africa on donkeys. Drug cultivation is such a lifeline that the children clothed and fed with its proceeds have a name: bana bamatekoane (children of marijuana).Bana is children, and the ba being a possessive preposition, of in this case.
Bana ba Lesotho, The Children of Lesotho
Bana ba ka, My Children
