What North African country does not have a strong farming sector?

The answer would be Libya.

Egypt has a large agricultural sector, as the Nile Delta and Valley are highly fertile. Egypt exports significant amounts of cotton.

Morocco provides exports of cereal crops, grapes, olives, and livestock; agriculture employs 40% of the Moroccan workforce. Morocco is also a major supplier of the illicit crops marijuana and hashish.

Tunisia grows citrus, grains, olives, cattle, and almonds.

Algeria grows wheat, barley, and potatoes, contributing 14% of the workforce and 8% of GDP.

Libya lacks a strong agricultural sector, due to poor soil and limited rain. Mining and hydrocarbon extraction make up 95% of Libya's economic output.
