Classification & economic significance of common crops
Narrated lesson · press play
Stand in the Oshakati market on a busy Saturday: sacks of mahangu, heaps of groundnuts, sweet oranges, bottles of cooking oil. Every one came from a crop a farmer chose to grow. But which crops feed a nation, which earn export dollars, and which does dry Namibia have to buy in? In this lesson we sort every common crop into its class and learn why each group matters for food, cash, factories and trade.
