Olives and olive oil are readily exportable for markets around the world. Jordanian bananas need custom tax protection to be sell-able even in the local market, let alone trying to export them!
Olive farms are all over Jordan supporting many Jordanian families and labor. Banana farms mostly employ underpaid expatriate workers in exploitative situations.
Need we say more? Why can’t we just focus on the agriculture that makes sense in a country struggling to save the little water resources it has?
