Caption by Space Station Academy student: Showed in the picture, is a pivot cultivation located in Qassim, Saudi Aarabia. The pivot cultivation, is a method of irrigation (used mostly because it's really cheap), where a motor moves in circles in order to water the crops, that's why it looks like this from above. Though Qassim grows grapes, dates, lemons and others, this particular image shows the cereal crops. Qassim is one of the most important regions in Saudi Arabia, to cultivate and export cereals; is actually so important, that every season, thousands of people of different countries and regions, travel to Qassim to fulfill their markets with grapes, oranges, pomegranates and vegetables. The city of Buraydah, located inside Qassim, is a dates producer worldwide. Something awesome about this dates cultivations, is that they celebrate each September a dates season ceremony, where people from all over the GCC countries, gather together to celebrate and buy their yearly requirement of dates. They also buy camels, in one of the biggest camel markets in the world.
