I want to know the answer to the following question:
How many tonnes of Cassave is produced per year?
All the background I'm provided with is that "Food crops are not exported in large quantities, but still constitute the principal cash crops of the country, because Central Africans derive far more income from the periodic sale of surplus food crops than from exported cash crops such as cotton or coffee.[citation needed]". Is that enough to answer the question?
Answer: no
