Explanation:

As you may already know, the criada were military expeditions organized by the Catholic Church, with the objective of creating battles in the sacred places for Christianity and expelling the Muslim population, or of other religions. These sacred places were the Holy Sepulcher and Jerusalem in Palestine.

During the invasion of these ligars, the Catholic army looted and took many things from the Arab people to Europe. Among these things can be mentioned rice, apricots and melons. This depleted the Arabs' food reserves and caused them to increase their demand for food in order to meet the needs of the people.
