In Medinet El Faiyum, Egypt, the installation of a noria has been successful in increasing food security despite the lack of rainfall in the region. Farmers are able to harvest three times a year despite the fact that the region receives only three days of rain a year. This is thanks to waterwheels that were introduced several centuries ago by Ptolemic engineers. They are still working today side by side with electric water pumps to grow olives, vegetables, fruits, nuts, sugar cane, rice, and wheat.
