Because the reason why the Arabian Peninsula didn't have a big farm is because they had a good amount of food and Although its not surplus food they had to pay taxes and so forth and they couldn't even afford the money to the build a bigger farm plus the Arabian have to travel too far places just to trade
The Arabian Peninsula has small amounts of farming due to its desert climate, limited water resources, and poor soil quality. Additionally, the focus on oil production and economic factors further limit agricultural activities in the region. These combined challenges make it difficult for farming to thrive in this environment.
