Answer
Mesopotamia
Explanation
Mesopotamia is a region between the two rivers Tigris and Euphrates in western Asia. They depended on annual flooding to produce a constant surplus of food because the floods brought silt which was very fertile to the lands and it contained the minerals required by the soil and the nutrients which helps the plants to be more productive.
Also in Egypt floods along the river Nile helped farmers in good production of plants because it carried black soil to their farms which was very fertile.
The tribune Gaius Gracchus proposed that the government supply wheat to Rome "as free rations within the city, so that the urban poor in Rome could be fed <span>below market prices," since this was seen as being helpful to the overall economy of Rome. </span>
